[guide] Blu Vivo XL4 | | Vivo Xi || Vivo Xi+ - Android General

The BLU VIVO XL4 has arived.
Sorry this guide is not for very new users, it relies on certain amount of prior knowledge.
**NOTE**
Unlocking Bootloader WILL set warranty flag to "NO"
Make the read-back backup, BEFORE unlocking, so there is a possibility to restore warranty to "yes"
Getting SPFlash Tool to work on BLU VIVO XL4
I used sp flash tool version 5.18.28
Needs custom DA file and Auth file. Both have been found from a near clone device.
Open flash tool select the DA file and Auth file from the link below.
add the scatter file from archive. There is a preloader file in the archive also. This is needed for spflash tool to open the Auth file.
Stock Rom and Auth file
Then follow the guide found on youtube.
Not planning to go into too much detail about the actual pulling of the firmware, as there is already
a fantastic guide with step-by-step photos and also a video.
Just the basics
Pull stock rom with spflash tool once just from the "boot region" to get the preloader file.
Process that file with the Wwr_MTK tool to get partition table information.
And one more time pull as one large binary file from the "user region" then split it into
individual images using the tool called "Wwr_MTK" it can be found on other site(Hovatek). I cannot put a
link as it is against forum rules (no advertising other forums)
But there is a youtube video that describes the process. And gives link for download of the tool.
**NOTE-1**
The Wwr_MTK tool did not have the correct chip (mt6762 In fact the "family class" for the chip is mt6765) as an option. Because of this you will need to add it to the tool before using it. Open the downloaded zip.( I used "WwR_MTK_2.40_Eng" ). Open "Template.ini" with text editing software, in the section labeled "CPU" add "MT6765 2" , keep same format as the rest of the file. Save the changes and close Template.ini.
Now when you run the tool, you will be able to create the scatter file as you split the rom into files.
**NOTE-2**
The tool connects to internet and downloads fresh the files and scripts when you start it. There is a 30 second ad screen displayed. If you block internet to the tool, then the add screen turns into 2 minute wait screen. I am not suggesting that you hack the tool to by-pass it, just letting you know what to expect.
IT IS HIGHLY RECOMMENDED TO MAKE YOUR OWN FULL BACKUP BEFORE PERFORMING THESE STEPS
AFTER YOU HAVE MADE FULL BACKUPS
Now to start modifying
DOWNLOAD
UNLOCK BOOTLOADER
unlocking bootloader is no more complicated then then enabling OEM unlock toggle in dev options menu.
Then performing Command in terminal. Just like so many android devices.
Unlock Bootloader
1. Enable Developer options on phone:
open settings--> "about device"--> click build number 5-7 times--> go back one screen in settings
-->select more "more settings" --> scroll to bottom "Develpoer options" --> enable "usb debugging"
2. Open cmd or power shell terminal
3. reboot phone to bootloader with the following commands
Code:
adb reboot bootloader
4.Once the phone has finished loading into fastboot mode type this command
Code:
fastboot oem unlock
I also did --MIGHT be an optional step
Code:
fastboot flashing unlock
Do not think both were needed.
After each command when phone was rebooted,
it took extra time to open. But did not show the normal recovery screen while
it did the factory reset. But a reset did happen both times,
as I had the setup wizard each time.
Even after unlocking bootloader, doing a "fastboot boot *xyz.img" (boot or recovery test images)
Phone would only cycle to off then do a full reboot. Doing "fastboot flash boot boot.img" does flash the boot.
And "fastboot flash recovery recovery.img" does flash the recovery.
TWRP
1. Download TWRP From Link above
2. Enable Developer options on phone:
open settings--> "about device"--> click build number 5-7 times--> go back one screen in settings
-->select "more settings" --> scroll to bottom "Develpoer options" --> enable "usb debugging"
3. Open cmd or power shell terminal
4. reboot phone to bootloader with the following commands
Code:
adb reboot bootloader
5. Now give the command to flash twrp, assuming you downloaded the file to default download folder
Code:
fastboot flash recovery %userprofile%\downloads\TWRP-3_2_3-1020-OMFG-mod_b6-device-name-vivo-wipe-misc.img
5. Reboot to twrp. Needed to boot directly to twrp, or stock recovery will be re-flashed by phone.
Code:
fastboot oem reboot-recovery
Once inside twrp It is asking for password to unlock (decrypt)***automatic decrypt not work on this device as of YET***
this is supposed to be same password used to unlock phone.
Because this twrp does not work with encryption, every time you reboot you will have to select language, if changed from default.
To get recovery to be functional, you need to make phone patched for both "DM-Verity" and "Force-encryption"
I do this with
"Universal Disabler"
https://forum.xda-developers.com/android/software/universal-dm-verity-forceencrypt-t3817389
There is similar utiliy built into this Recovery image.
to use the built in option , Select ADVANCED, Then RM Forceencrypt
This will flash the lazypatcher with options set to remove encryption both in boot.img and /vender/*fstab : remove dm-verity.
--OR-- manually do the following steps
Steps
1. Download Zip from Link above.
2. Open TWRP
3. Open Wipe menu
4. Select format /data
5. Key in "YES" and swipe
6. Return to Home Page of TWRP
7. Choose reboot menu then recovery
8. Recovery should now have access to Internal memory (temp for now)
9. Use abd push to put the zip file downloaded above to internal memory
Code:
adb push %userprofile%\downloads\Disable_Dm-Verity_ForceEncrypt_12.16.2018.zip /sdcard/
10. Select install menu , and install the Disable_Dm-Verity_ForceEncrypt_12.16.2018.zip
Do not rename the file. It installs and makes the patch base on the file name.
If you want to have root also, then flash Magisk at this point.
Now the dm-verity and force encryption are off. You can flash gsi custom rom, if you desire. At the moment, I have only been able to boot the phone with working cell data and calls on the PHH-Phusion --vanilla builds. Do not know why the gapps versions do not allow rill to function.
As of the writing of this I have put up V4 of the TWRP port. This version uses the correct mount points for this phone, not the ones from the source of the port. Also corrected the device name in default.prop, to match device name. Build fingerprint has been left as is. Fixed the micro sdcard name and OTG names. Added mipe to the "misc" /"para" partition to escape a factory reset recovery loop that [uu]could[/u] happen under certain situations.
And my prefered ported recovery from LRTeam TWRP-3_2_3-1020-OMFG-mod_b6-device-name-vivo-wipe-misc.img.

Kernel sources have been published 12-12-2018, by BLU
I have them synced to GitHub while I make test builds.
https://github.com/mrmazakblu/BLU-VIVO-XL4-kernel
Default defconfig should be arch/arm64/config/k62mv1_64_bsp_defconfig. Based off of build description in "getprop"
Built kernel has not been able to be booted yet.
TWRP is first ported and provided thanks to @Voinea12
.

placeholder not really welcomed here on XDA
just pm a moderator or report this thread when you`re ready to upload something, until then, thread closed

After seeing that the Blu vivo xl4 requires an "auth file" in order to flash with spflash tool, I asked BLU to supply the file.
They responded with a big fat NO.
.......
.......
THE NEXT DAY THE FILE WAS POSTED ON A DIFFERENT THREAD.
SO THERE HELP WAS NO LONGER NEEDED.

Just made successfull readback on preloader. and currently reading full rom.
will post link when done.
here is auth file and DA file I used.
pulled firmware is here.
there are more images in complete firmware, but the ones included should be enough , as long as you NEVER do format all from spflash tool.
STOCK ROM

So far all attempts to load twrp have failed.
Also just tried to flash boot.img with the built kernel. When rebooted, phone just stayed on black screen. No back-light , nothing.
Just a repeating connect disconnect sound from pc. Long pressing power and trying to get into the bootloader menu failed.
Was able to Que up sp flash tool and keep holding the volume down button , on the next time it cycled on off preloader was caught and i was able to flash back the correct boot.img.
Working version is available now

Thread was opened.

My streak with SP Flash is still a losing one, the auth file works for my phone as well (Blu Vivo XI+), I just used the preloader.img that was in the update.zip and ran it through the WwR MTK Tool and got the preloader.bin to go with the auth file as you indicated you had done, that was one hurdle that your post helped me solve, but for some reason when I start reading the full rom I get about 6-10 MB into it and then it disconnects from my phone and stops. Not sure if its driver related or what, which drivers did you use for the readback?

To be honest I have not installed driver specific for this. I have vcomm drivers installed, same from couple years ago.
Is the readback stopping because you set wrong hex address length in the readback tab?

No, I got the readback of the EMMC_USER just fine and ran it through the WwR MTK tool and it gave me the hex address to use for the full rom readback, t then told me
Code:
The file size is smaller than the start position of the LK (uboot). To determine the type of processor and memory, it is necessary to read the full firmware in the SP Flash Tool, specify the parameters for reading: Start address: 0x0, Lenght: 0x1D1EC00000.
So I entered those two addresses as EMMC_USER readback. If my phone is off and I just connect it to the usb without holding any keys it gives me another error.....and I'm an idiot. just figured it out as I was looking at logs, apparently I must have changed the usb speed in sp flash which changes it's pid causing it to try and read from another port. It's downloading now

Thanks to @hanuma there is now a material themed twrp port.
The V2 version loads. But has no adb or mtp access

******EDIT*****
Most of the following problems did not repeat in same way when I tried to repeat the install process.
Main issue was with simcard. But exact process to get installed and working is still not known.
-- install after already having rooted, encryption removed stock, seems to work.
-- fresh full stock rom, full encryption, then gsi seems to not work sim card.
PHH-treble gsi images do boot this device. I do not have a bug list as yet.
working:WITH encryption removed:
1. wifi
2. camera
3. fingerprint- unlock
4. music
5. video
NOT working :WITH encyyption removed:
1. cell signal
2. cell data
3. phone
4. sms
---------------------------------------------------------------------------------------------------
---------------------------------------------------------------------------------------------------
working:WITH encryption enabled
1. phone
2. sms
NOT working:WITH encryption enabled
1.. everything else
EDIT
Much of the force closing problems were from a corrupted external sdcard. When I removed the card , the force close messages did not come.
Getting 4G data connection was not stable. after a full reset and rom re-install I was not able to get data connection, and only able to have connection to make calls when set to 3G connection only.
some bugs in vendor I assume will need some help solving this.
EDIT 2
Finally got around to trying again. his time I started with vanilla version of phh-treble gsi.
4G data and sms, calls in out all work. Camera , video both work.
WiFi tethering did not work.
Setup that worked :
force encryption removed with universal dm-verity patcher, ( bothboot.img and vendor partitions both edited).
magisk patched boot

Would this work on Blu Vivo XI since same chipset?

It should. I have been working with few users with Xi+ it works for them. And another user of Xi provided a twrp port, but no details on if this read-back worked. It must have, I suppose it must have.
Please do try to do the readback for your self, and share the files. will help with twrp if I can

Guide has been revised.
The original guide suggests to format /data and patch device to remove force encryption. This works fine for stock rom, and modifying stock rom. But I have found that removing encryption will not allow the phone to work as a phone when flashed with GSI. The down side is, at the moment, there is no twrp that is working to read the encrypted /data.

No, you need fastboot(PC preogram) to unlock bootloader and either sp flash tool or fastboot to flash recovery.

I just did this, and it worked the first time. I got into the phone and set it up. But it was super laggy after a while. So I decided to reset the phone like how you would normally do to fix a problem, and now... it’s making me boot into the recovery each and every time I try and boot into the system... i installed the gsi rom "PixelExperience for AOnly" at max lees site

dont panic. this is minor bug. Easiest way to solve is to flash stock recovery. and do factory reset from there.
You can install image from twrp or fastboot, even spflashtool.
It is from the flag that is set into para(misc) partition.
You can clear it manually with terminal also, or even use one of the othe rtwrp images I shared. One with "misc" in the file name.
If you use one of those recoveries and do reset will also clear that reboot condition

STEP BY STEP GUIDE FOR LG V20 H918 UNLOCKING BOOTLOADER, DOWNGRADING, ROOTING AND INSTALLING CUSTOM ROMS (NOOB FRIENDLY)
DISCLAIMER: I'M NOT THE DEVELOPER OF ANY OF THE BELOW SOFTWARE'S AND YOU PROCEED WITH YOUR OWN RISK AS THIS INVOLVES BRICKING OR DAMAGING YOUR MOBILE IF THE PROCEDURE IS NOT FOLLOWED CORRECTLY. I'M JUST SHARING THE WHOLE PROCESS WHICH I HAVE FOLLOWED TO ROOT AND INSTALL TWRP IN MY LGV20 H918 UNLOCKED T MOBILE.
AND I HAVE TESTED THIS IN MY OWN DEVICE AND WAS ABLE TO ROOT AND ACHIEVE TWRP.
THIS IS ONLY FOR LGV20 H918 VERSION
ENSURE INTERNET IS UP AND RUNNING IN YOUR PC
EDIT: THE WHOLE PROCESS HAS NOW BEEN AUTOMATED IN TWO SIMPLE STEPS TO PREVENT ANY POTENTIAL DAMAGE TO YOUR DEVICE. THANKS TO THE LAFSPLOIT CREATOR BRIAN @runningnak3d.
JUST FOLLOW THE PROCEDURE BELOW AND YOU SHOULD HAVE YOUR DEVICE ROOTED IN NO TIME
1. BACKUP ALL YOUR IMPORTANT DATA BEFORE PROCEEDING.
2.MAKE SURE YOU HAVE CHARGED YOUR PHONE TO AT LEAST 90 PERCENT
CHECK YOUR PHONE SOFTWARE VERSION IN SETTINGS---ABOUT PHONE----SOFTWARE INFO
IF IT IS ANYTHING BETWEEN H91810P TO H91810U MEANS IT IS ARB1 (ANTI ROLL BACK 1) AND YOU NEED TO USE LAFSPLOIT METHOD TO ROOT AND INSTALL TWRP,
IF YOUR VERSION IS H91810O OR BELOW (ARB0), YOU CAN EITHER USE DIRTYCOW OR LAFSPLOIT METHOD FOR THE SAME.
IF YOU ARE ON ARB1, PLEASE FOLLOW THE METHOD BELOW,
PART 1: DOWNGRADING
IF YOUR VERSION IS H91810 (Q, R, S, T, U) YOU NEED TO DOWNGRADE TO A LOWER VERSION ( H91810P) TO EXECUTE LAFSPLOIT.
IF YOU ARE ALREADY ON H91810P, YOU STILL NEED TO RE FLASH THE H91810P KDZ AGAIN FOR THE LAFSPLOIT SCRIPT TO WORK CORRECTLY.
DOWNLOAD H91810P KDZ FILE FROM BELOW
https://androidfilehost.com/?w=files&flid=282709
DOWNLOAD AND INSTALL ALL THE FILES BELOW IN YOUR PC
UPPERCUT AND LGUP----
http://downloads.codefi.re/autoprime/LG/Flash_Tools/LGUP/
LG DRIVERS---
http://tool.cdn.gdms.lge.com/dn/downloader.dev?fileKey=UW00120120425
CONNECT YOUR MOBILE TO YOUR PC IN DOWNLOAD MODE (SWITCH OFF YOUR MOBILE AND CONNECT THE USB FROM PC WHILE HOLDING THE VOLUME UP BUTTON SIMULTANEOUSLY)
RUN UPPERCUT.EXE WHICH WOULD OPEN LG'S UPDATER TOOL AUTOMATICALLY.
INSIDE THE LG UPDATER TOOL, CLICK ON BIN AND SELECT THE H91810P KDZ FILE DOWNLOADED EARLIER.
NOW SELECT UPGRADE AND FLASH
ENSURE THE USB CABLE IS CONNECTED THROUGH THE FLASHING PROCESS AND WAIT FOR YOUR PHONE TO REBOOT AND THEN REMOVE THE USB CABLE.
CHECK THE SOFTWARE VERSION AND ENSURE IT IS H91810P
PART 2: UNLOCKING BOOTLOADER
HEAD TO SETTINGS---ABOUT PHONE----SOFTWARE INFO (ENSURE IT IS H91810P)
ENABLE DEVELOPER OPTION IN YOUR PHONE BY CLICKING ON THE BUILD NUMBER MULTIPLE TIMES
NOW HEAD TO SETTINGS---DEVELOPER OPTIONS
TURN ON OEM UNLOCKING, ENABLE USB DEBUGGING AND DISABLE 'VERIFY APPS OVER USB'
NOW CONNECT YOUR PHONE TO PC AND OPEN ADB COMMAND CENTER PROMPT IN YOUR PC
adb devices---->CHECK IF YOUR MOBILE IS CORRECTLY RECOGNIZED IN ADB
adb reboot bootloader--->THIS REBOOTS YOUR DEVICE IN FASTBOOT MODE
fastboot devices---->CHECK IF YOUR MOBILE IS CORRECTLY RECOGNIZED IN FASTBOOT
fastboot oem unlock---->THIS COMMAND WOULD UNLOCK YOUR BOOTLOADER AND RESET's YOUR DEVICE.
fastboot oem device-info OR fastboot getvar unlocked ----->THIS WOULD CONFIRM IF YOUR BOOTLOADER HAS BEEN UNLOCKED OR NOT.
fastboot reboot-----> THIS WOULD REBOOT YOUR DEVICE
IF THE BOOTLOADER HAS BEEN SUCCESSFULLY UNLOCKED, THE DEVICE WILL SHOW AN UNLOCKED BOOTLOADER WARNING MESSAGE WHILE BOOTING (THIS CAN BE IGNORED OF COURSE)
PART 3: CREATING A BOOTABLE LINUX USB USING FWUL
DOWNLOAD FWUL_v2.7_x86_64_15GB.zip FROM THE LINK BELOW AND EXTRACT THE IMAGE FILE SOMEWHERE IN YOUR PC.
https://androidfilehost.com/?w=files&flid=214529
DOWNLOAD RUFUS FROM BELOW AND INSTALL
https://rufus.akeo.ie/
INSERT A PEN DRIVE IN YOUR PC AND RUN RUFUS.
INSIDE RUFUS SELECT THE IMAGE FILE AND SELECT START (AFTER SELECTING START SELECT DD MODE IN THE DIALOGUE BOX) TO CREATE A BOOTABLE PEN DRIVE (WARNING: THIS WOULD FORMAT YOUR PEN DRIVE)
NOW YOU SHOULD BOOT YOUR PC FROM THE BOOTABLE USB STICK WHICH YOU HAVE JUST CREATED
THIS WOULD MAKE YOUR PC RUN LINUX OS
TYPE PASSWORD AS linux AND ENTER
PART 4: INSTALLING TWRP AND ROOTING USING LAFSPLOIT
BEFORE PROCEEDING ENSURE YOU BOOT YOUR PHONE AND DONE ALL THE BASIC SETTINGS
NOW HEAD TO THE DEVELOPER OPTIONS IN YOUR DEVICE AND ENSURE OEM UNLOCKING AND USB DEBUGGING ARE SWITCHED ON.
NOW CONNECT YOUR DEVICE TO THE PC (RUNNING LINUX OS FROM PENDRIVE) IN DOWNLOAD MODE (SWITCH OFF YOUR MOBILE AND CONNECT THE USB FROM PC WHILE HOLDING THE VOLUME UP BUTTON SIMULTANEOUSLY)
DOUBLE CLICK ON THE LG FOLDER INSIDE FWUL DESKTOP
INSIDE THAT, DOUBLE CLICK ON LGLAF(RUNNINGNAK3D) ICON WHICH WILL OPEN A TERMINAL
ENTER THE BELOW COMMANDS
git pull
git checkout h918-miscwrte
./step1.sh
THE ABOVE COMMAND FLASHES TWRP RECOVERY ONTO YOUR DEVICE.
WAIT AND PULL OUT YOUR DEVICE WHEN IT ASKS TO.
RECOMMENDED: NOW THAT TWRP HAS SUCCESSFULLY INSTALLED, YOU CAN MANUALLY FORMAT,FLASH LATEST TWRP RECOVERY AND USE ANY METHOD LIKE MAGISK OR SU FOR ROOTING.
INSIDE TWRP RECOVERY. FIRST FORMAT USING WIPE--ADVANCED FORMAT--TYPE yes AND FULL DO A FULL FORMAT, THEN FLASH MAGISK AND THE LATEST TWRP RECOVERY BELOW.
MAGISK ZIP DOWNLOAD:
https://github.com/topjohnwu/Magisk/releases/download/v16.0/Magisk-v16.0.zip
LATEST TWRP BY PHOENIX(H918):
https://forum.xda-developers.com/v20/development/recovery-twrp-3-2-1-0-t3720239
OR
IF YOU ARE UNSURE ABOUT FORMATTING AND FLASHING, JUST USE THE BELOW COMMAND TO DO ALL THE WORK AUTOMATICALLY
CONNECT YOUR DEVICE AGAIN IN DOWNLOAD MODE AND ENTER THE FOLLOWING COMMAND
./step2.sh
THE ABOVE COMMAND FORMATS YOUR DEVICE AND FLASHES MAGISK TO ACQUIRE ROOT.
TIP : IF YOU FACE ANY ENCRYPTION ERROR AFTER USING STEP2. SH, DO A ADVANCED FORMAT WITHIN TWRP AND FLASH MAGISK AND LATEST TWRP BY PHOENIX MANUALLY.
YOU ARE NOW ROOTED WITH TWRP RECOVERY INSTALLED.
REMEMBER TO BACK UP THE CURRENT ROM BEFORE FLASHING ANYTHING..... DO CHECK POST #2 FOR OTHER TWEAKS
IF YOU WISH TO UPDATE TO LATEST STOCK (10U) AND KEEP ROOT AND TWRP, JUST FOLLOW THIS LINK AND DO REMEMBER TO ROOT USING MAGISK AFTER FLASHING THE ROM BEFORE YOU BOOT.
https://forum.xda-developers.com/v20/development/rom-h91810q-stock-rom-twrp-flashable-zip-t3681312
I WOULD LIKE TO THANK ALL THE DEVOLEPERS WHO HAVE CREATED THE ABOVE SOFTWARES WITHOUT WHICH THIS ISNT POSSIBLE.
CREDITS:
@autoprime FOR HIS UPPERCUT TOOL
@steadfasterX FOR HIS FWUL TOOL
@Phoenix591 FOR HIS WORKS ON TWRP RECOVERY
AND FINALLY, @runningnak3d FOR HIS EXCELLENT WORK IN ROOTING OUR DEVICE :good:

WHAT NEXT?
NOW THAT YOU HAVE ROOTED YOUR MOBILE, I WOULD RECOMMEND DOING THE BELOW TWEAKS FOR FURTHER ENHANCED EXPERIENCE....
1.THERMAL THROTTLING
IF YOUR ARE STILL ON A STOCK BASED ROM , I WOULD STRONGLY RECOMMEND TO RECONFIGURE YOUR THERMAL FILE TO PREVENT ANY POSSIBLE LAG WHEN USING EXTENSIVELY...
FIRST DOWNLOAD THE FILE BELOW:
https://drive.google.com/file/d/0B0W3xXHgfOxvLUpKNWhrWDE0TDg/view
USE A ROOT EXPLORER (PREFERABLY ES EXPLORER) AND GO TO ROOT/SYSTEM/ETC.
YOU SHOULD HAVE A FILE NAMED thermal-engine-8996.conf
RENAME IT TO thermal-engine-8996.conf.bak (JUST FOR A BACKUP IF ANYTHING GOES WRONG)
ENSURE THE ABOVE DOWNLOADED FILE IS IN .conf FORMAT
IF IT ISN'T , RENAME TO thermal-engine-8996.conf
NOW SAVE THE FILE TO THE SAME DIRECTORY VIZ ROOT/SYSTEM/ETC
GIVE PERMISSION TO THIS FILE TO rw-r--r-- USING THE ROOT EXPLORER ( SELECT FILE--->PERMISSION--->READ WRITE, READ, READ)
FINALLY SAVE AND REBOOT.
THIS WOULD OVERWRITE THE THERMAL LINKED PERFORMANCE OF THE CPU TO AVOID ANY LAG WHEN USING EXTENSIVELY.
2. RCTD REMOVER
ALSO I WOULD STRONGLY RECOMMEND TO REMOVE THE LG'S RCTD CCMD AND TRITON MONITORS AS THESE WOULD RUN CONTINUOUSLY IN A ROOTED LG PHONE AND CONSUME LOT OF RESOURCES...
JUST INSTALL THE RCTD REMOVER APP FROM BELOW LINK:
https://labs.xda-developers.com/store/app/com.zacharee1.rctdremoverforlg
GRANT SU PERMISSION AND CHECK THE DESIRED FILES (I CHOSE ALL THREE FILES) AND CLICK ON PATCH, FLASH IMAGE AND REBOOT (THIS WOULD PATCH THE BOOT FILE, SO AGAIN IT IS ADVISABLE TO CREATE A BACKUP OF THE CURRENT BOOT IMAGE USING TWRP OR WITHIN THIS APP ITSELF)
3. SCREEN CALIBRATION:
https://play.google.com/store/apps/details?id=com.grarak.kerneladiutor
INSTALL KERNAL AUDITOR APP FROM PLAY STORE AND GRANT SU ACCESS
CHANGE THE BELOW VALUES WITHIN THIS APP (SCREEN SETTINGS)
Minimum RGB value = 35
Saturation Intensity = 27
Screen Hue = 1520
Screen Value = 112
Screen Contrast = 132
THIS WOULD SOMEWHAT REDUCE THE BLUE TINGE AND GHOST APPEARANCES OF THE SCREEN

I was just about to create a post asking for a step by step for dummies so thank you very much for this! Going to do this sometime tomorrow or Tuesday and will update if I succeed or not. :good:
Got a question. Does this method stop the second screen from working?

this would end up with a stock rooted phone with twrp recovery if all the methods are correctly followed..
......final result would be.... you would end up with a rooted stock rom with a twrp recovery....
your second screen will work perfectly.....
please let me know if you need a different thread for installing custom rom, and to reduce the lag., install sound mod to get maximum sound output and customize second screen... i will create a noob friendly thread for these as well......

Thank you, I've been reading up on the main lafsploit thread for awhile but I was still not sure about the whole flashing KDZ file and stuff so when you posted this thread it was a motivator to try it out. Got a day off from work tomorrow so gonna try it then so I don't got to worry about the time.
I'm interested in the max sound output and second screen customization if you got the time and its not to much to ask. If you want to wait till either someone else comes along thats interested or till I root just so you don't waste your time I shall update hopefully sometime tomorrow. Thanks again.

Excellent. Just a friendly suggestion, however. I would change the instruction above to use the word EXACT instead of SIMILAR, otherwise people may continue erroneously. The hash numbers must be exact.

so i just wanted to say thank for for the very noobie step by step guide. im soooo use to odion and adb flash commands.
just 1 thing i had trouble with was trying to push magisk and twrp over. I rooted by pushing magisk over with otg but no twrp on recovery. then i saw it said it was on download mode. from dl mode i just flashed twrp to recovery.

Abr1 yes I am rooted with twrp.
As I said, the commands to push magisk and twrp to sd did not work. I used usb otg in twrp to push magisk, but forgot to put twrp to flash as well.
I forgot that twrp had replaced download mode, so I was going a bit nuts trying to figure out how to get twrp to recovery. Lolol
Now I'm on latest update with rtcd removed thanks to the op who hosted it on xda as a flashable zip.

Hi guys, sadly I'm at the last step and got stuck.
I did everything, and managed to get to the part where you WIPE de data using TWRP, Mount, but when I go and type
adb push Magisk...
adb push h18...
I get an error saying that Cannot stat : No such file or directory
I'm unable to figure out what I'm doing wrong
Any idea?

While you are in the last step, in mount, select otg USB. You can push it to SD card and manual flash.
If you booted to system without magisk and flashing twrp, power off the phone, hold volume up, put in the USB, connect to PC. This will put you in twrp since download mode is replaced by twrp.
Now you can flash both files.

Below you will find a download for my modification of a ported Team Hovatek TWRP file as their TWRP did not support OTG. Thanks to Team Hovatek for making a nice porting tool. Unfortunately it took some days and late nights of work to get the ported TWRP to actually be useful as this phone needs OTG support to use TWRP.
When I recently got the Unihertz Atom I didn't realize that it had no micro SD card slot for an external SD card like the Unihertz Jelly Pro had. However it does have OTG support unlike the Jelly Pro but I could not find any TWRP versions for the Atom. So I found a TWRP porting tool from Hovatek and I was able to create a TWRP version but USELESS unfortunately as that version of TWRP did not have OTG support for the Atom.
To make matters worse that TWRP can't deal with the encrypted internal storage of the Atom so there was no way to do a backup of your system. It was possible to format data in TWRP and do a backup to it but upon reboot all that data was gone and reset by the Atom as an essentially new phone being setup for the first time.
I needed a way to modify the ported TWRP so it would recognize an OTG flash drive or USB flash with an OTG cable. I used Image Kitchen to disassemble the original Atom Recovery image and also the modded TWRP recovery image so I could find what was missing from TWRP that was there in the original setup. After a whole lot of reassembling and reflashing various attempts to fix the OTG problem I finally got it. Had to add different lines of code to 3 different files within the unpacked TWRP recovery for it to finally recognize an OTG attached flash drive.
A couple notes on using your external flash drive with TWRP. First you want to insert the flash drive with an appropriate USB type C OTG adapter or cable. Or I see Sandisk (and possibly other brands) are now making a flash drive with USB and Type C dual setup for OTG use.
Bootup your regular phones Android system and look in the pull down notifications - it will ask if you want to use the flash drive as storage. Answer yes and it will then Format it to FAT32 0x0C type which is different than what it was fresh out of the package as most will be FAT32 0x0B type. Once formatted the way the Atom wants it you can use it. However if you put the drive back in your Windows computer it may not see the drive at all. The solution is to open Windows Disk Management and Assign it a drive letter. Once that is done you can read and write to it from both Android and Windows or Linux.
Once that is done you can turn off your phone (IMPORTANT). Do not use any apps that reboot into recovery after installing this TWRP or you will likely just get a black screen and it won't boot up until you reflash the preloader, boot and recovery.
To get into recovery hold down the Volume UP button and the Power button at the same time until you see Unihertz then release both. This is of course after you have flashed TWRP. More on that below. Once your are in TWRP you may have to remove your Flash drive if you had it plugged in during recovery boot up - then reinsert it for TWRP to see it. You can then see it when you mount storage or select storage and it should show the size of your flash drive.
You can then backup your Boot, Recovery, EMMC, System and cache. However the data on the Atom seems to be encrypted in a way that this TWRP does not see it so it will be best to use something like Titanium backup for your Apps and their data. The TWRP though will ensure a complete backup of your system and it's settings as well as the other items mentioned above. I am still looking into why it can't see the encrypted data part of the phone but for now it's nice to have an image of all the rest of the phone. If anyone can help with that I would appreciate it. So far I've tried several 'no encrypt scripts' and ones to turn off DM verity I found on XDA but none of them worked on this phone.
Here is the download of my modded TWRP and also a link for the SHA-256 of it:

Notes on Installing this TWRP on your Atom
There are two ways I have used to install this TWRP onto the Atom. One way (and the best way IMO) is to use the SP Flash tool version 5.1828. The other is to use Fastboot. I believe for both methods you need to enable developer options on your phone and turn on OEM unlocking. But if you use Fastboot you also have run the line: "fastboot oem unlock" to install TWRP and that will wipe your phone to a new reset condition plus you will see the 5 second "Orange State" pause screen every time you turn on the phone. To eliminate the "Orange State you can run : "fastboot oem lock" but that will once again totally reset your phone wiping everything including apps and settings. So I prefer using SP Flash tool to avoid all that.
When installing with SP Flash tool I always flash the preloader, boot and recovery (the TWRP modded one) and of course the scatter file. It seems if you don't flash all of those it sometimes doesn't want to boot up.
Also this mod is for the official Unihertz 11-30-2018 ROM version which is the latest update I've seen as of a week ago. I don't know if it will work for other versions. You will want to download that ROM to get the scatter file that is needed by SP Flash tool and it's always good to have an original ROM just in case. Link for the new 11-30-2018 Atom ROM here: 11-30-2018 Atom ROM If you are not on that version you could backup your apps and data with Titanium backup and then install the new ROM while flashing my modded TWRP all at the same time. Just make sure the TWRP you download is named "recovery-verified.img" when you replace the stock one in the SP Flash tool list on the Download page. Also make sure on the tools 'Connections' setting that you check 'Battery installed'.
IMPORTANT!!! - Every version of SP Flash tool I've used shows up as having a virus or trojan and although it may probably be a False positive to be safe I always run Shadow Defender before starting the SP Flash tool. There may be other similar programs but I found this to be one of the best as it totally freezes your computer and hard drive(s) so nothing can be changed or written permanently to them while in Shadow mode. Once you reboot everything is back to a normal state and any changes that may have been made are gone. SP Flash tool available here: SP Flash tool v5.1828 I strongly suggest you use this latest version as previous ones had some issues in completing this project.
A couple quick notes on using the SP Flash tool: It is best to start the tool, have all your items in the check boxes loaded (select scatter file location first) check and locate preloader, boot and recovery - the preloader and boot are from the original ROM you downloaded from the above link. Unzip it and you'll see the needed files inside along with the scatter file.
Once that is ready turn OFF your phone and hook it up with the original USB-C cable to your computer. Wait for it to show the battery charging screen and wait till all that disappears and you have nothing but the black screen. (Or per user SepticFuddy you can hold the Volume Up key while inserting the USB cable and it will connect quickly - I have not tested it this way). Then click on the Flash tool download button. After that you need to push the Atom Power button once briefly - not long enough to turn it on - just a brief click. After that you should see the Flash process going on - it only takes a few seconds to load the preloader, boot and recovery and then you will see a "done" with a big check mark. Remove your phone then and boot into your regular Android OS or use Volume Up and the Power key to boot into your TWRP. :highfive:

Why TWRP doesn't work with Encryption - from TeamWin
I guess this may explain why it is unlikely to get TWRP to work with the encrypted data partition - straight from Teamwin's TWRP website:
"Why doesn't TWRP support encryption on my device?
TWRP encryption is supported in 2 phases. The first item is keeping up with the newest support from AOSP, which can require lot of changes and integration with the new AOSP release. This can take time especially if we have to wait for reference devices to test with. The second item is custom blob support and integration with device OEM firmware.
Even if your device supports AOSP encryption and decryption, it usually requires custom blob support. The process of figuring this out may take time and may never be done. Some vendors such as Samsung use their own encryption techniques. Without heavy deconstruction/decompiling of custom library blobs, and successful ports by an active maintainer, this may never be done. Encryption support is a nice thing to have in TWRP, and not a must have support option. We feel that the ability to backup system and install custom firmware can outweigh having no TWRP support at all."
From: TWRP Website FAQ on Encryption

How I fixed TWRP
For anyone who wants to try the mods their self if you don't trust using the recovery I uploaded I believe these are the changes I made to the ported TWRP. You need of course the porting tool from Hovatek and after you have ported your original recovery you will want to use Image Kitchen to make these mods to the ported image:
Use Image Kitchen to unpack the ported TWRP recovery. In the Ramdisk folder this line "ro.agui.otg_usbdisk=yes" orginally found in the prop.default of the original recovery needs to be put into the file "default.prop" which is a different file name than the original but I am sure is the same purpose and was referenced in the original by a small file with that name.
Then this line "/dev/mt_otg_test(/.*)? ubject_r:mt_otg_test_device0" from the original recovery image in the file "nonplat_file_contexts" I believe I copied into the file "file_contexts" in the TWRP image in the Ramdisk folder.
Note - the above code line that has a smiley in it is because there is the letter "o" followed by a colon. Replace the smiley with "o" and : no spaces between it and the letter 'u' before it or between 'o' and :
I think the third file I modified was found in the unpacked folder /ramdisk/etc in the file 'recovery.fstab' and I took this line "/devices/platform/mt_usb* auto vfat defaults voldmanaged=usbotg:auto " from it to add to the same file in the ported TWRP. Then just repack everything in Image Kitchen and you should have a TWRP recovery that works with OTG.
If you aren't familiar with how to use Image Kitchen it would be best to google how to use it. I have left out some of the basics such as needing to Copy the “recovery.img-kernel” and “recovery.img-kernel_offset” from the unpacked stock recovery and overwrite those two files in ported TWRP folder. Best to look for an instruction article on techora.net about porting TWRP on mediatek devices.

Thank you, it's awesome! But how did you manage to flash Magisk? I can't flash it as /data and /storage can't be mounted.

You should be able to flash it with Fastboot by using command:
fastboot flash boot /path/to/patched_boot.img OR simply put it in the fastboot folder and type:
fastboot flash boot boot.img (the patched boot image)
You may want to review info on the Magisk thread here:
https://forum.xda-developers.com/apps/magisk/official-magisk-v7-universal-systemless-t3473445
This method of course is done with you computer and USB cable attached to the Atom. Make sure you have correct drivers for it to fully recognize your phone.
A bit more info from topjohnwu's Magisk thread mentioned above:
Via Magisk Manager:
This method does not need root, and also does not require a custom recovery.
However, you MUST have a stock boot image dump beforehand, and you also have to be able to flash the patched boot image, either through fastboot/download mode or ODIN
Install the latest Magisk Manager
If you're planning to flash the patched boot image through ODIN, go to Settings > Update Settings > Patched Boot Output Format, and select .img.tar. For normal users leave it as the default .img
Press Install > Install > Patch Boot Image File, and select your stock boot image file
Magisk Manager will now patch your boot image, and store it in [Internal Storage]/Download/patched_boot.img[.tar]
Copy the patched boot image to your PC. If you can't find it via MTP, you can pull the file with ADB:
adb pull /sdcard/Download/patched_boot.img[.tar]
Flash the patched boot image to your device and reboot. Here is the command if using fastboot:
fastboot flash boot /path/to/patched_boot.img

If the above method fails for some reason you should also be able to flash to patched boot image with SP flash tools as long as you have the scatter file for the ROM you have installed on your phone. As I mentioned if you flash the patched boot image that way I found it best to also flash the preloader and recovery at the same time.

Cannot mount /data
What you did here was remarkable. I love the Atom so I never tried to tinker with recovery since I might end up with a bootloop. I hope we find a solution soon on how to mount /data.

post-root network failure
First off thank you for doing the research and posting in the thread to help us root this awesome little device.
I followed your steps to the "T" and I was able to successfully patch magisk and re-download it back onto my atom and it was rooted BUT, there seems to be some sort of network issue that I'm stuck on, I'm unable to turn on the wi-fi and bluetooth and every few seconds I keep getting an error message that says "bluetooth keeps stopping" consistently whenever I have the phone on.
I was wondering If you had any idea on what might be causing this, or if you had this problem.
thank you, and I look forward to hearing back from you

droidzer1, Finally got to post now and wanted to thank you for your work on the Atom. I got it rooted and got TWRP working too with only some frustrations because I got in a hurry and missed a detail the first try. I haven't found any problems and have had it running about 2 weeks now with root and TWRP. Nice to have root and of course great to be able to do a whole system backup now!

Were you able to get this fixed? Doesn't look like droizer1 has been on here recently. Mine didn't have either of those issues. Have you tried doing a factory reset and doing the whole process over? I think sometimes just a computer PC might glitch something on your phone so doing it over might skip the hiccup.
---------- Post added at 03:48 AM ---------- Previous post was at 03:08 AM ----------
Since droidzer1 first posted this in early January you might try using the version of Magisk that was available at that time as I think by later March when you posted there was a newer version out and I've found some versions of Magisk to not work a hundred percent and had to use an older version on some phones.

The latest Magisk (19100) + Xposed (v90 beta 3) work fine for me using the TWRP posted above, in case people were wondering about it.

Lost in reboot ...
Hi
I urgently need some help. I seem to be lost...
I have successfully installed TWRP on my Unihertz atom. And I can manage to go into either TWRP mode or into fastboot mode.
I can also successfully unlock the Unihertz atom with:
fastboot oem unlock-go
But what is next?
If I reboot, my phone constantly reboots. It cycles into reboot without Android coming up.
(perhaps I made something wrong).
What I actually want is: The phone should boot including Magisk.
Can anyone please help me what commands I have to issue (with the phone connected to my linux computer via USB) in order
to recover to a normal reboot? Which image-file should I use (please provide URL)?
Can anyone please help me what commands I have to issue to flash Magisk?
Which image-files I should use (please provide URL)?
If somebody has a custom rom or lineageOS rom I would be even happier ...
Thanks a lot.

Thank you

Confirmed working with the Android 9 Pie 2019082617 ROM, latest Magisk 19.3 (19300), latest Riru core v19.5, latest Riru- EdXposed v0.4.5.1b (4463) (SandHook). EdXposed seems hit or miss after a reboot though, getting it to stick may take a few installations.
To get SP Flashtool to work, I had to hold the Volume Up key while inserting the USB cable and it would instantly connect, rather than following the OP's instructions of just inserting the cable and waiting for a black screen.
I'd love to see a custom ROM like LineageOS or something, but this is will have to do for now.

Me too!! LineageOS for the Unihertz Atom would be great!
The hadrware of the Uniherz Atom is just great, is is small and it is dual-sim. This is unique in the market.
I would be even willing to contribute with 100,- EUR if somebody delivers a working LineageOS ROM.
Any body interested? :highfive:

The main problem is that unihertz never released their source code (despite being obliged to do so according to the android licensing contract).
There are some bits in the official mediatek kernel source tree (https://android.googlesource.com/kernel/mediatek/) but I doubt that this would be enough to build something stable out of it.

@droidzer1 Hey there, what is the difference between your modded TWRP and this test release by the TWRP Builder Project asside from the TWRP version?

I'm not sure what the difference is except I came out with mine in January and theirs came out in March. Theirs is about 4 Megabytes bigger - maybe a newer version (mine is 3.2.1-0). I contacted 'bigbiff' at TWRP about mine when I had it working but they were not interested unless I had a device tree which I didn't so they didn't want to post it on their site.

Great, thanks for your reply. I am satisfied with you version, so I will just keep using it.

Disclaimer: This guide and the tools included are provided as-is. Testing has been limited and nothing is guaranteed to work. I take no responsibility for lost data, bricked devices, etc. Continue at your own risk, and please read carefully. THIS GUIDE WAS WRITTEN FOR PHONES ON ANDROID 8.1 - MAY NOT WORK ON DEVICES WITH THE PIE UPDATE.
Note that Magisk and TWRP can interfere with downloading and installing OTA updates. At this time the only updates are security patches, so it would be best to make sure all OTAs are installed before starting.
Mounting and decrypting the data partition is still hit-or-miss. If you haven't set up a passcode or password, TWRP should be able to mount it, and you still might be able to even if you have. Magisk will corrupt encrypted partitions and force a factory reset, and TWRP will not be able to help you back things up if Magisk has been installed before disabling encryption. You've been warned.
Guide: Installing TWRP and Magisk on the Visible R2
Tools:
prog_emmc_firehose_8917.mbn - firehose for flashing system partitions
Latest available TWRP zip - contains TWRP recovery image and the necessary files for flashing
fstab.qcom - for removing forced encryption
Patched boot image - for installing versions of Magisk newer than v16.7
Stock firmware - optional, but handy to have in case something goes wrong.
Windows users: QPST/QFIL and the QDLoad drivers (possibly the first set of ZTE drivers as well, but likely not necessary). Installing drivers in compatibility mode for XP or Windows 7 might help resolve issues.
Install adb if you don't already have it set up.
Linux users: qdl source code; the guide will cover compiling and installing it. You'll also want to install adb from your distro's repositories. There is a snap package for qdl, but it doesn't work for the purposes of this guide, so please don't use it.
Part 1: Installing TWRP
TWRP is an easy-to-use, touch-based custom recovery for Android devices, designed to make backups and installs simple and painless. Unfortunately, the installation of TWRP on the R2 is going to be a little less simple and painless; the device's bootloader isn't locked down, but it doesn't support fastboot commands, meaning we'll need to get our hands dirty to flash partitions.
Before starting, it's also worth noting that the current TWRP build cannot always decrypt encrypted data partitions, and the device is encrypted by default. This means that TWRP may not be able to mount or back up your data partition unless it's formatted and forced encryption is removed (see part 2).
To flash TWRP, we need to put the device into EDL mode and forcibly overwrite the existing partitions using an EDL tool and the firehose linked above, which unfortunately requires a PC of some sort. Enable USB debugging on your phone, then follow the steps for your operating system below.
For Windows:
1. Install the Qualcomm driver package. Before continuing, you will need to make sure Driver Signature Enforcement is disabled on your PC; QFIL may have issues communicating with the device if Windows blocks the driver.
2. Install the QPST package, then open QFIL from the Start menu.
3. Select 'Flat Build' under Select Build Type.
4. Extract the TWRP zip to an accessible directory (something like C:\TWRP works fine). Place the firehose.mbn in the same directory.
5. Press 'Browse' under Select Programmer, then navigate to the TWRP directory and select the firehose file.
6. Press 'Load XML'. Select rawprogram_recovery.xml, then patch0.xml
7. Connect the phone to your PC and make sure USB debugging is enabled. Make sure your PC is trusted by the phone for ADB commands, then send 'adb reboot edl'.
8. If everything went well, the phone should have rebooted with a blank screen, and QFIL should be asking you to select a port. Press Select Port, and then choose (hopefully) the only item available).
9. The 'Select a port' message should now read something like Qualcomm HS-USB QDLoader 9008 (COM#). IF it does, simply press download.
10. There should be some output in the status window, ending a few seconds later with a blue Download Succeeded message. If so, you're done, and can restart your phone. If there's a red error message, or the status window seems to be stuck on sending, double-check that your device is registered properly in Device Manager.
11. Once you're done flashing, you can reboot into TWRP by holding down the Vol Up button as the phone reboots.
For Linux:
1. Unzip the qdl zip into its own directory, then enter the directory.
2. Compiling qdl requires libraries that may not be installed. For Ubuntu users, you simply need to run ' sudo apt install libudev-dev libxml2-dev' to install them; people with other distros should know how to use their package manager and may have to find the packages under a similar name. If any other packages are required (errors compiling, etc.), let me know so I can update this.
3. Actually compiling should be as simple as opening a terminal in the working directory and running 'make && sudo make install'. If you get no errors, qdl should be installed and able to run from any location, and the compile process shouldn't take much time at all.
4. Before running qdl, ModemManager needs to be disabled, as it can interfere with accessing the phone in EDL mode. In Ubuntu (and most systemd-based distros) you can ensure that it's stopped by running ' sudo systemctl stop ModemMangager'. If you need the ModemManager service, make sure to restart it when you're done.
5. Extract the TWRP zip to an easily-accessed folder, like ~/twrp, and place the firehose mbn in the same folder.
6. Navigate to the TWRP folder and open a terminal there. Now would be a good time to plug in your phone and enter EDL with 'adb reboot edl'.
6a. If your phone was already connected in EDL mode before stopping ModemManager, you might need to reboot it and enter EDL again.
7. If you're in the same directory as the TWRP files, you should be able to start flashing by running 'sudo qdl prog_emmc_firehose_8917.mbn rawprogram_recovery.xml patch0.xml'.
8. If everything's good, you should see some output on your screen, and the phone should reboot momentarily. If the command finishes without output, ModemManager or something similar may have interfered. Make sure ModemManager is stopped, reboot your phone into EDL mode again, and try again. If it hangs at Waiting for EDL device, you're not running the program with admin privileges or your phone isn't in EDL mode.
9. Once the process has finished and your phone has rebooted, you should have TWRP installed. Boot into it by holding Vol Up while rebooting.
That's it! Verify that TWRP is working as expected by doing some test backups and restores, etc. Note that TWRP builds for this device are still sort of experimental; decrypting the data partition may not work for some users, and keeping data encrypted while trying to flash Magisk will not work - you will need to wipe and decrypt the device. If you're satisfied just with TWRP, there's not much else you need to do. If you want to run Magisk or decrypt your device for other reasons, keep reading.
Part 2: Removing Forced Encryption
By default, the device encrypts the data partition without input from the user. This is not ideal, and even if TWRP can decrypt and mount your data partition, from my experience Magisk's init process apparently gets things wrong and tries to write to data before its decrypted - whether that's actually the case or not, the fact of the matter is that Magisk has corrupted my data partition every time I've tried to install it while data was encrypted.
DO NOT flash any zip that removes dm-verity and force encryption - these modify the boot and recovery partitions, and the stock kernel doesn't like the way they do it. If you've flashed the patched boot.img first then you'll at least be able to boot to your system partition afterwards, but it'll still nuke recovery even with a custom kernel installed on it. If you're still using the stock boot.img, you'll get boot loops and won't be able to access recovery; your only choice is to enter diagnostic mode, and reflashing anything from that point is a gigantic pain in the ass, so please, just don't. If you feel the need to do it regardless, please please please reflash your boot and recovery images before rebooting.
Counter-intuitively, the quickest and most painless way to stop the device from force-encrypting itself is to modify the fstab on the vendor partition - the boot partition has no fstab files, and the ones in the TWRP recovery image are already set to make encryption optional. Place the fstab.qcom on the phone's microSD card (internal storage will work if you don't have one, as long as TWRP can access your internal storage; if not, use adb push/pull rather than the below commands), boot into TWRP, and adb shell into your device by USB; if done while in TWRP, you should have root permissions. If your PC doesn't see your phone as an ADB-ready device, go to Mount settings in TWRP and tap on the option to disable MTP; after confirming that ADB works, feel free to re-enable MTP. Once ADB is working, run the following commands:
Code:
mount /vendor
cp /vendor/etc/fstab.qcom /external_sd/fstab.qcom.bak
cp /external_sd/fstab.qcom /vendor/etc/fstab.qcom
chmod 644 /vendor/etc/fstab.qcom
umount vendor
.
That's the simple part - you've replaced the fstab on the vendor partition with one that tells the device that encryption is optional, and backed up the original to your microSD as fstab.qcom.bak, just in case. Now you need to actually remove the existing encryption, which will wipe all the user data from the device. If that hasn't scared you out of continuing, read on.
While we're still in TWRP, we need to go to the Wipe menu. From there, we need to Format Data. It'll give you warnings in a scarier color than I did, but you'll have to type yes and continue regardless. Once that's done, hit the back button a couple times before rebooting. Do a standard factory reset, then reboot.
From there, it may take a couple tries for the device to boot normally as it reformats and repopulates the data partition. If you find yourself stuck on a black screen, reboot again, and if it keeps happening, boot into TWRP and then reboot to System from the reboot menu. Eventually, you should be able to get back to the device setup screen, and depending on your security settings beforehand, you may be prompted to enter your PIN, password, or Google account information.
From here, you should be able to mount, backup, and restore your data partition in TWRP without any issues. If you want to go further and root your device, keep reading for the Magisk guide.
Part 3: Any Magisk You'd Like
Note: Magisk and encrypted data partitions do not play nicely together. Follow through Part 2 first, or you'll have headaches.
ZTE's kernel has a custom SELinux plugin called policyproc, which in short doesn't play nice with a lot of things that modify what happens during the kernel's startup sequence. Unfortunately, modifying the startup sequence is what Magisk does best, and versions of Magisk past v16.7 don't play well with the stock kernel.
If you're fine with v16.7, you can download the zip from its Github release page and flash it through TWRP. However, it doesn't support current versions of Magisk Manager or the uninstaller zip, and naturally it doesn't have all the features of newer versions.
This is where the patched boot image comes in. Basically, it's the stock kernel, rebuilt with policyproc disabled, stuffed into the stock boot.img and replacing the original kernel. It's not entirely perfect as ZTE deliberately left out bits of the source, but even working around that, the kernel seems to run fine after nearly a week of testing on my own device. Still, if you run into any issues that don't show up with the stock kernel, please let me know.
So. you can take that patched boot image and install newer versions of Magisk whichever way you'd like. The default method would be to use TWRP to flash the patched boot image, then flash the latest Magisk zip (v20.1 at the time of writing). Alternatively, you could put the patched boot.img on your microSD or internal storage, install the Magisk Manager app, use it to patch Magisk into the patched boot image, then use TWRP to flash the patched-patched-image to the boot partition. Either way should work fine, and honestly I'm hoping if you've made it this far you don't need further instruction on how to get Magisk installed.
Note that on the first reboot after installing Magisk, the phone may reboot again before loading the system normally. I assume this is standard practice for initializing Magisk, but honestly I have no idea.
With that, you've done just about everything you came here to do. If you still feel like tweaking and possibly bricking your phone, however, scroll on down to Part 4.
Part 3.5: Updating Your Magisk Install
When a Magisk update is available, the Magisk Manager app will generally push a notification to you. Letting the manager handle the upgrade is a good way to get bootloops, unfortunately; upgrading requires re-patching and re-flashing the boot image, and most apps running in system mode seem to handle the task poorly on the R2. If you want to update to a newer version of Magisk, it'd be best to reboot into TWRP, flash the 'clean' Magisk-ready boot image, then install the zip for the version of Magisk you want to update to. You don't need to uninstall previous versions of Magisk to do this, and it should be doable even if a previous Magisk upgrade left you stuck in a boot loop. Note that if you previously told the Manager to 'hide' itself, you may end up with two Manager apps after the update; it should be safe to remove either of them, although the one with the Magisk Manager name will need to be re-hidden if you choose to keep it.
Part 4: Going Even Further Beyond - Project Treble and You
Google requires that all Android phones releasing with Android Oreo or newer must support the Treble framework: generally speaking, anything that's 'stock' Android lives on the system partition, and anything manufacturer or carrier specific exists on the vendor partition. This has allowed for developers to create generic system images, or GSI, consisting of particular Android system partitions that should run on a variety of Treble-enabled devices. And wouldn't you know it, the R2 launched with Oreo, and you've got a couple handy methods of writing system images to your device, through TWRP and EDL flashers.
So, does that mean the R2 supports these GSIs? Not really! Honestly, it's more that it's up to curious people to find out. I've been able to get phhussons's Oreo image working, but that's a bit boring on a device that supports Oreo out of the box. A couple more highly modified Pie builds failed to boot properly, either hanging on their splash screen or crashing the display manager before getting through setup.
There's also the fact that they're generally only distributed as sparse system.img files, something I had trouble flashing with QFIL, and up until about 18 hours before this guide went live, the only TWRP build I had for the R2 could only write images to the boot and recovery partitions, not system, so writing them meant I had to decompress them to a standard EXT4 image and then flash them with QFIL, which wasn't a lot of fun to mess with. In short, testing's been pretty limited, but this build of TWRP should make it much easier for anyone to flash whatever image they'd like. If you feel like being a guinea pig, we'd all love to hear the results! If you want to test, you should look for A-only, ARM64 images.
Questions and Issues
My phone is bootlooping after leaving recovery!
If you haven't messed with system partitions in a way that might cause a bootloop, reboot to recovery and try to boot to system from there. If it continues, reflash your boot image (and Magisk afterwards, if necessary, removing the extra Manager app that might pop up in your app tray if you've got Manager disguised in its settings).
I can't access ADB or MTP from recovery.
It happens sometimes, especially in Windows; just toggle MTP on/off from inside TWRP, or unplug and replug your USB cable.
My phone says I need a factory reset, but TWRP just reboots.
This generally happens if something messed with the encrypted data partition. Do not tap the factory reset button on your phone; instead, power off entirely and manually reboot into TWRP by hilding Vol Up while booting. Perform a factory reset (and format data if necessary) from there, then reboot.

Attempted to flash the new twrp via zip....acted like it worked but when I when to install section only boot and recovery were options....so I installed the twrp image itself to recovery....rebooted back into recovery and got a black screen. Additional attempts to go into recovery did same thing. I'll attempt to use the flashify app under factory rom to restore previous copy of twrp. It should work as I had magisk going...I think.

That is... not really reassuring. I've suspected the zip flash might not actually work, but I double-checked that TWRP build on my device first.
What's weird is that that's also the only TWRP image I've gotten to boot without dragging it through an AVB signing process. Let me sign that image and reupload it, see if it works any better.

Always possible I hosed something....I grabbed the img of the previously good twrp and flashed it via flashify app...said it worked but when booted to recovery got same black screen. I'm about to experiment with the usb drivers you mentioned vs the ZTE USB ones in the op...they conflict with each other so uninstalling old ones.

If the ZTE and QDLoad drivers conflict, I'd probably say keep the QDLoad. I honestly don't remember if I ever installed any ZTE drivers other than the ones that can be served from the phone by USB.
Pretty sure flashify is just broken; I tried it the other day with the same results after flashing a test build that didn't work at all.
I just redownloaded the TWRP from the original link and it worked fine, and there shouldn't be any files or signature tied to my own device, so I don't really know why it wouldn't work on other phones. I've got another one coming in the mail for actual use on Visible, but it won't be here to test on until tomorrow.
In the meantime, try this TWRP. No different other than letting AIK give it an AVB signature, but some of my test images wouldn't boot otherwise. If it works I'll update the zip in the first post.

If I su from adb and do a dd if=twrp-signed.img of=xxxxxxxxxxx can I overwrite it manually from shell and if so do you know the path I should use to get it to our recovery?
If flashify is broken, twrp is broken and I'm unable to use qdl nor qfil I'm kinda screwed (for the moment). The qdload drivers did not show the device on a com port when in edl mode...the zte ones do but then again I can't write anything. Any ideas what the heck is up with the linux qdl? Even with --debug it says nothing.

I tried dd if=twrp-3.3.1-1-z5151v.img of=/dev/block/bootdevice/by-name/recovery and did same with new signed one. I still get black screen when recovery "loads". At this point I'm going to have to get something figured out with qdl or qfil.

Yeah, I wasn't sure if dd was going to work or not.
Try the QDLoad drivers again in Windows, make sure that the device is using them. If it's not showing up as a COM port in device manager, force it to use the proper Qualcomm driver, which on my system installed to C:\Windows\system32\qcusbcer.sys - I don't know if that installed with the QDLoad drivers or with QPST/QFIL itself.
As for qdl, I don't know; it's been hassle-free for me, for the most part. If you're sure you're in EDL mode and not diagnostics or something, an output from lsusb might help diagnose the issue. If the debug flag isn't providing useful info, might as well try it without. I don't know if there's services other than modemmanager that might interfere with qdl, it could depend on distro.
EDIT: I'll also preemptively warn against trying the TWRP app to flash; it'll do about as much good as flashify.

Will tackle it "later" in the morning. Thanks for the quick followup. I might see more clearly in morning when not so frustrated with it. I swear I haven't had this many issues with getting twrp installed in a long time.
*update* Ok so I lied....I completely recompiled qdl from https://github.com/andersson/qdl and it's working as expected..I used it to flash the original twrp. I then used that twrp to flash the twrp-signed.img and rebooted back into it with no issues.
I also flashed your patched boot and it got as far as the blue visible screen after the zte one then hung. I reverted to my nandroid copy of boot.

The Treble pie loaded ok...I did do a factory reset so data would not conflict..it did do one reboot before loading normally. See screenshots.
The First 4 are from when it was initially installed. The later photo's I had added gapps, a few apps, snapped a picture to use as wallpaper and various other minor things. I found it to be faster under treble pie than it was with factory oreo. I haven't found anything that didn't work yet on it.

Did you still have Magisk installed at the time? I'd have recommended uninstalling Magisk using the uninstaller zip from the 16.7 release before replacing the boot image; if there's still Magisk data in /data then booting with a non-Magisk boot image is probably going to cause issues.
In the meantime, I guess I'll update the TWRP zip with the signed recovery image, just in case.

I also installed open gapps pico pie amd64 version on top of the pie rom without issue. I have magisk 16.7 working with treble without issue so maybe it was just the newer versions that had issues?

My 2nd R2 (You are a bad influence) arrived today. Anything you need tested on a stock model? Here's hoping qdl/qfil cooperates 1 last time.
When you were patching the kernel did you see anything that was keeping the phone in LTE only mode for calls? When I get a minute I'm going to put my t-mobile sim into the R2 and see what it will do under the pie rom but since it's still using same kernel I wondered if that would be an issue. We know on the stock rom all calls have to use VOLTE.

I haven't figured that much out yet, unfortunately. I don't know if it's due to the way the kernel is built, or custom libraries distributed on the vendor partition, or what. From what I can tell, the bands are properly unlocked in the NVRAM, and I don't really know enough about modem firmware to make heads or tails of those files.
I will note that for people using the phone on Visible, using a non-stock ROM works for getting around the one-connected-device-per-hotspot limit.

Had a couple of thoughts...a quick and dirty method to provide "flash and go" rom's might be to do a nandroid of just system or maybe system and boot for whatever rom and make that available for download. I also know there are methods to convert a nandroid into a flashable zip although I haven't done it before. This was more a thought for folks wanting to go to b12 that already had twrp...simple enough for an existing b12 user to back up system. I have verified swapping between nandroid pie vs stock oreo works ok (assuming you are restoring the right data for each). Also the fingerprint "images" continued to work fine after a restore.....on a previous device when we did a nandroid restore we would have to delete the file storing pin/fingerprints as they wouldn't let you into the phone until re-recorded. It also worked if you remember to turn those OFF before doing the backup....wasn't an issue with the R2. The phone is noticeably more responsive on pie than it was with stock oreo. I'm curious whether you found that to be the case with treble oreo?
Oh minor annoyance....I changed the device id to z5151 which is what it showed under stock but when doing an adb shell the command line is "phhgsi_arm64_a:/" Do you know how to change that? This will change it temporarily till next login: https://stackoverflow.com/questions/33069161/how-to-change-adb-shell-prompt-name-before-the-mark

You could try using setprop as root to set ro.build.product or ro.product.device back to Z5151, or manually edit the build.prop; beyond that, I don't know of a simpler way.

Welcome to this little thread in which I'll provide every useful information about this device based on my and other users's experiences. If you know something, that I didn't mention, please reply to this thread in order to help out each other even more effectively. Thanks and pleasant reading!​
The Lenovo S5 Pro is a very decent mid-ranger with good specs and even better pricing. We all know, that chinese manufacturers tend to install bloatware on their products time to time. In our case, Lenovo didn't release a single update since 2018 Novemer to this device. It means, that it came out with Android 8.1 Oreo (2018 November Security Patch) and left untouched. This is even worse, than Meizu which is famous for it's neglecting policy of software updates for global users. Now, that we know all this, it's not a surprise, that we are here on our favourite developer forum.
*** General information | Links | Downloads | Credits ***​
The official global firmware is now saved and available (thanks to our forum member nikosddesign) here: download & link to the post
Everything you will possibly need (PC software, drivers, stock camera app, VoLTE modem etc...) is available in this Yandex Disk, you just have to navigate to each one. (Most of the content is in russian, since Yandex is the russian Google, but it's not hard to find the files you'll need).
The previous links and the following tutorials are only available, because suninterbru (from 4pda forums) and radiationofthenation provided these informations and the tutorials, also so much thanks to everybody on the 4pda forums, who provided useful information and files, большое спасибо!
Even though the bootloader unlock, TWRP install and rooting should not cause data loss, be careful and create a backup. You can back up only your files and data or your whole ROM, it's up to you.
Please note, that after you've unlocked your bootloader, everytime your reboot or turn on your phone a warning will pop up during the boot process for about 1 second. On Android 9.0 Pie vendor the message pops up for about 5 seconds. The warning is about the side effects of modifying the system software and it also says, that it is not recommended to store any personal data on your device anymore. Please ignore this message, since it's only popping up, because manufacturers usually don't like, if you modify your device.
Pro tip: If you keep pressing your power button for a little longer you can skip the alert and boot faster.
*** Bootloader unlock ***
Please note, that your warranty will become invalid/void after you unlock your bootloader or root your device.​
0. In your device's developer settings enable bootloader/OEM unlock and USB debugging.
1. Visit the official ZUI bootloader unlock website.
2. Enter your IMEI1 number in the first field. (You can find your IMEI numbers in Settings\About or in the dialer enter: *#06#).
3. Enter your serial number in the second field. (You can find your serial number in the fastboot menu). The one in the settings is not good in this case! (To access the fastboot menu, turn off your phone, then press the power button and after you see your screen light up, immediately press the volume down (-) button or while it's turned on and USB Debugging is enabled, simply type in the terminal/cmd ,,adb reboot bootloader").
4. In the next field enter your email adress. (Please note, that Tutanota won't work, Gmail is recommended or other not secure email providers).
5. Enter the verification numbers in the last field.
6. Tick the checkbox.
8. Click on the blue button.
7. Now check your inbox and/or spam folder, because Lenovo just sent you your custom sn.img, only for your phone.
8. Save the sn.img to your PC and install ADB drivers system-wide. (Thank you Snoop05 for your work)!
9. Open a terminal/cmd on Windows. You should be in the same directory, where your sn.img file is, with the terminal. To change directories type ,,cd your directory goes here" and hit ENTER.
10. Run the following commands:
- adb reboot bootloader
- fastboot flash unlock sn.img
- fastboot oem unlock-go
11. Congratulations! Your bootloader is now unlocked!
*** TWRP Recovery ***​1. Download the .img file from here.
2. The steps are similar to the bootloader unlocking:
- adb reboot bootloader
- fastboot flash ,,downloaded" .img
- After the flashing is done DON'T reboot to the system, instead navigate to the ,,Reboot Recovery or Recovery Reboot" option and select it. (Volume keys and power key - you know the drill) This will ensure, that the TWRP Recovery doesn't get ereased on reboot(s)!
3. After you've successfully rebooted into TWRP, you should root your device with Magisk, to prevent the recovery erasure!
*** ROOT ***​1. The good old SuperSU is no longer in the picture, but don't worry a new player is in the game. Download Magisk from here. (Thank your for your work topjohnwu)!
2. After you've downloaded the flashable .zip copy it to the main directory/root of your device.
3. Reboot to TWRP.
4. Click install, select the flashable .zip file.
5. The installation process should start.
6. Reboot, after finished.
7. Check if Magisk Manager is installed or not, if yes tap and update it.
8. If you did not succeed, please check the Magisk topic for solutions or reply to this thread.
*** Factory reset | Stock ROM | Unbrick | LOST IMEI/PERSIST/EFS | QCN BACKUP/RESTORE ***
!!! NEVER EVER TICK ,,ERASE ALL BEFORE DOWNLOAD" IN QFIL, OTHERWISE YOU WILL LOSE YOUR IMEI AND THE ABILITY TO CONNECT TO MOBILE NETWORKS !!!​
If you accidentally clicked on that option you will have to restore someone elses QCN backup. (It will not work, if you backup your own QCN and rewrite your IMEI and restore it, so do not waste your time with that)! Luckily, a member of the 4PDA forums published their qcn backup. (большое спасибо geepnozeex)! QCN backup for Lenovo S5 Pro. (I modified the link, because the original one is no longer valid)
1. Download the linked QCN file.
2. Make sure, that you are on one of the Stock ROMs, however the recommended ROM is this one.
3. You will have to be rooted to put your device in diagnostics mode. To do that, follow this tutorial.
4. You will have to edit the QCN file with HxD, in order to write your own IMEI into.
5. Open the file with HxD and search for 08 8A 76 06 06 14 57 95 32. This is the IMEI 2. You will have to insert your IMEI 2 from the box here, but first you will have to convert it into Hexadecimal numbers.
6. Convert your IMEIs into Hexadecimal numbers here.
7. You will have to rewrite and insert your values insted of the previous one.
8. Search for 08 8A 76 06 06 04 67 98 72. This is IMEI 1. Convert your IMEI 1 into Hexadecimal numbers, too and replace.
9. Save the file (Ctrl + s)
10. Open QFIL and click on Tools, then QCN Backup/Restore.
11. Choose the QCN file, you wrote your IMEI into.
12. Click on Restore QCN.
13. There is a chance, that the process/progress bar won't finish till the end. No problem, just reboot to EDL mode through TWRP/Advanced and restore the recommended stock ROM.
14. You should have everything working fine, now.
To factory reset or unbrick your device, follow this tutorial on 4PDA. [Don't panic you don't have to know russian, just follow the instructions on the pictures! To see the pictures, click on the bold text.] ,,(спойлер (+) (Инструкция по прошивке)" ~ or ~ Download any of the previously linked STOCK ROMs to your device's main folder and flash them through TWRP. Most of them are in flashable .zip formats and should work well. A simple factory reset in TWRP is recommended before installing any of the ROMs, be careful this action will erease your data from your phone!
(Please note, that most of the time you'll have to use the QPST/QFIL method, because the flashable .zip files always expect a specific vendor version, usually a lower one, so you can upgrade with flashable .zips, but possibly can't downgrade, so you have to use QFIL)!
*** GSI custom ROMs ***
Our device is arm64-aonly, so please only use according GSIs. Note, that I will link only those GSIs, which are booted successfully on my device!​
~ phhusson's official GSI list: here
~ phhusson's AOSP GSI (Android Open Source Project): here
~ developerluke's ExpressLuke GSIs: here
~ eremitein's CAOS GSI Project: here
~ eremiten's LOSQ GSI Project: here
~ igors1974's Amber GSIs: here
~ tunasahinn's and yek4perf's Tunahan's GSI builds: here
~ mrsshunt3r's albus-gsi: here
Note, that you should keep up with the developments and update your system, if needed! These are just a few GSIs, that I've tested personally on my phone, but you can always keep up with the latest news and try new GSIs out, thanks to phhusson's official GSI list!
*** How to flash an Android 10 GSI ***​
1. Download the latest custom phh-magisk from here. (Thank you developerluke and phhusson)!
2. Download the latest Disable_Dm-Verity_ForceEncrypt from here. (Thank you Zackptg5 and others)!
3. Download your desired GSI.
4. You can flash from an USB-OTG flash drive or from the storage of your phone. (I personally have a dedicated USB for this purpose).
4.1 If you are coming from stock ROM you will most likely need to Format Data in this step, because the Disabler won't be able to decrypt the data and, that will cause a stuck at the boot logo!
4.2 Reboot Recovery
5. In TWRP perform a normal factory reset
6. Flash Disable_Dm-Verity_ForceEncrypt. (Cache wipe is optional).
7. Flash your GSI image.
8. Format Data (Skip this step if you already did this in 4.1)!
9. Reboot Recovery (Skip this step, too if you already did this in 4.2)!
10. Flash Magisk-phh
(11. Wipe cache/dalvik).
12. Reboot System
13. Enjoy!
*** Possible GSI bugs ***
Please note, that bugs can differ/vary on different GSIs, the numbers are not fully accurate!
​
1. The default camera app will work, however it doesn't support HDR, panorama or portrait modes. It also can't record in 4K resolution. Freezing is also possible. ~ 50%
2. First time, when you open the camera it'll stuck on loading, but after you go back and open it again it will work flawlessly. ~ 50%
3. No audio/microphone during phone calls. ~ 15%
*** Guaranteed GSI bugs*** ​1. The infrared face unlocking will not work, only fingerprint authentication is working. ~ 100%
2. You won't be able to charge your device while it's turned off, after you plug it in, it will automatically boot up. ~ 100%
3. Auto brightness. ~ 100% (There is a fix for auto brightness below)!
*** Camera fix (GSI) ***
(If you get ,,serious camera error" or your camera freezes on HDR)​
1. Download a custom camera app, where you can manually adjust the ISO level.
2. With OpenCamera, for example you have to adjust ISO to 800 and never above, because your camera will freeze!
3. So, always keep ISO 800 or under. With these settings even HDR shots are working!
*** Auto brightness (GSI) ***​1. Download framework-res__auto_generated_rro.apk from this thread.
2. Follow the instructions, which are described in this post. (You will need to have root to use ,,su" commands).
3. Thank you MishaalRahman and kAs1m for the apk and the instructions!

Twrp disappears when restarting
Help, twrp disappears when restarting. After installing it by: "fastboot flash recovery trwp.img". right there I start it with the "Vol + Power" keys and it starts correctly but when you turn it off and back in, "stock recovery" appears again. I also installed it again using the same twrp, but it disappears again.

You should not have flash the recovery image to the boot partition. These partitions are not the same, be careful! Now you can save your data from TWRP via MTP connection to your computer. After that restore your phone with QPST to the latest pie ROM or to the oreo ROM from yandex. The oreo ROM is flashable from recovery, it is easier.

Is it possible to just flash the boot partition (boot) again, if I get the boot.img from another rom?
I don't want to lose the stock rom:crying:

Maybe you can try to download a ROM file, extract it and flash the boot image, but I'm not sure if it is going to work.

on this page there are android 9, will it be true?
"https: // mirrors.lolinet.com/ firmware / lenovo /l58041/"
but first I will do it with the "O" stock, which you mention here.
I hope it will work again.

You should do the oreo version, if your were on the global oreo ROM. After that you can try the pie version, if nothing works don't worry you can do a backup of your data from twrp to your computer and flash a custom ROM or the chinese Pie version, which is recommended. With root access you can easily debloat the chinese ROM and with AdAway you can disable all communications pointing to chinese servers or websites. I also found these. Maybe you can give them a try.

After a few hours I was finally able to install the "Chinese stock rom", although I struggled, since the files of the "rom" of the l58041 do not quite coincide with the "stupdroid" tutorial and some files have two different versions, something like that:
here I chose the "ddr" .
prog_emmc_firehose_xxxx_ddr.mbn (.elf). prog_emmc_firehose_xxxx.lite.mbn (.elf).
here I chose the "retain_userdata".
rawprogram0.xml. rawprogram0_retain_userdata.xml.
and in qfil "Flat Build", however I don't know if it was the right thing because at the beginning I was asked for a password ("but that's another topic").
To add a language (without root), use local more apk.

I'm glad it is working for you now. Yes, you are right the tutorials flap at some points, but there are other tutorials which you can follow and make it work. For the first time I was struggling with the restoration, too. You will see, that the chinese ROM is quite good, you just have to uninstall the bloatware and disable spying DNS requests.

Ohh, explain more about spying. And also if you know something about the message that Android told me when I start. I remember that I flashed twrp.img using "fastboot", and when I asked for a password to decrypt, it only allowed me to clear cache and dalvit cache (I did wipe), and when I started again I showed a message saying that I was encrypting and a percentage, just here, I interrupted the process by turning off the cell phone, and flashed again with qfil (download). So when I start I just remember that I said something about the cell phone being restored and then I could restore the copy with my Google account. So what I think is that when the message of "TO START ANDROID ENTER YOUR PASSWORD" is displayed, it may work to interrupt or perhaps to put the incorrect password many times to automatically reset or also choose "rawprogram0.xml" in qfil (but I did not dare because it deletes it the information related to the imeil and the signal or at least that says some comments ). Now there is only one who can interpret what happened and to have clearer the restoration process, the rom seems to me very much the problem of the language is solved with "more local", I am from Mexico (At & t).

Hello
it's about 4gigabyte have to be patient.
i have very bad internet connection...

Hi everyone,
I have rooted my last few smartphones and was always happy with it. Now I got new Blackview BV9800 PRO and I want to root it with Magisk. but as the phone is new, there is lack of information on the internet, Anyway, I have found some information, but it is not complete and I believe You, smart guys, can help me to root my smartphone
This is the information I got:
How to root it with Magisk :
Download your rom from : viewtopic.php?f=285&t=532354 (you can alternatively extract it with SP Flash Tool and WWR)
Download and install Magisk Manager on your phone : https://github.com/topjohnwu/Magisk/rel ... v7.5.0.apk
Patch the boot image with Magisk Manager
Unlock the bootloader. (Wipe the phone! )
Flash the patched boot image with SP Flash Tool or Fastboot. (ONLY the boot image)
Reinstall Magisk Manager
This is what I did and what happened:
I installed latest Magisk apk from official sources. I opened the app, clicked on "Install Magisk", then via this app I downloaded the zip file, then tried to installed it via Magisk but got an error "Unsupported/Unknown image format".
Any ideas what have I done wrong? Did I have to flash boot image from the ROM, and not the one Magisk downloaded? P.S., the smartphone is new, nothing more then I written above is done to it (no oem unlocking, no usb debugging, etc).

RESERVED

I let Magisk manager patch the original boot.img. After flashing it with fastboot or SP Flash the phone stuck with message that verified boot didn't accept the signature.

Hm... Is there anyone who rooted BV9800 Pro successfuly and could guide us? ?

update fail.
I greet you, I accidentally deleted it when I updated, Nvram. on my phone. BV9800pro. It is possible to provide me with firmware recovered from a similar phone. I also posted on the forum at Blackview but without answer

Isn't there a full firmware download on Blackview website available? I thought I've seen it there

update fail

Hello
Yesterday during an update, by accident, my equipment, BV9800pro, performed a complete formatting, "Full Format + Dowload", it seems that Nvram has also been rewritten. it is possible to provide us with a solution or file with this data, specific to our equipment. i need a original nvram.bin, and nvram.data, in firmware from Blackview site this its not exist..
if someone wants to help me, I send them a private message with their email address

My phone is not rooted unfortunatelly, if I can help in anyway (if there is a way) I would pull out the files for You.
Do You know how to guaranteed root BV9800 Pro without running into problems?

rooting worked for me with that solution given to the PM. I wanted to install AOSP, but I found that the thermal image did not work anymore, there were some problems when previewing the video files from Facebook, and I gave up. from the mistake as I mentioned I format + dowload and delete all important partitions. nvram .bin si nvdata. Nothing works properly, TEE and Google Key are inactive, the thermal image fails, some applications are closed immediately. This is the experience with rooting and installing AOSP on the BV9800Pro

Oh man... Sounds bad... have You emailed blackview after sale support (via email, not forum)? No response from them?
And let's say I only root my BV9800Pro, will I be able to send You the files You need?

As I mention there's no TWRP available for this phone yet.

I just rooted BV9800 pro yesterday.
You don't need to SP flash tool or others, just need adb and fastboot.
Quick steps:
1. set OEM unlock to allow
2. connect phone to windows
3. use adb to check if connecting. command: adb devices
4. using adb to reboot to bootloader, command: adb reboot bootloader
5. And then the phone will enter fastboot mode ( you could see small string at left bottom corner)
6. use fastboot command to unlock bootloader. command: fastboot flashing unlock
7. If fastboot program is waiting, please check windows device manager, there should be an unknown device, let windows search driver automatically. it needs android interface driver.
8.Using volume up or down to agree unlock.
9. If agree, all data will be disappeared.
10. Install Magisk manger
11. Download stock ROM from blackview forum. it is zip file. Unzip it and copy boot-verified.img to phone.
12. patch boot.img by Magisk manger.
13. Copy patch image file to windows
14. use adb to reboot phone to fastboot mode
15. reflash boot image file. command: fastboot flash boot patched file name (normally, I would put patch image file in the same folder of fastboot)
16. reboot (fastboot reboot) and reinstall Magisk manager
There are many Magisk root steps instruction in internet. You could refer to other steps, they should be clear than mine. I prepared lots of drivers and application. Finally, I only used adb and fastboot to root this phone.

I rooted it exactly like You and it worked perfectly! Thanks for auch detailed rooting guide!
By the way guys, I think we Should open the request for TWRP for BV9800Pro. How do You think?

After you unlocked bootloader, it changed to orange state, and it always shows "Your device has been unlocked and can't be trusted..Your device will boot in 5 seconds", it could be resolved by modified LK image.
Refer to
1. https://forum.hovatek.com/thread-31664.html
2. http://bbs.blackview.hk/viewtopic.php?f=286&t=532899 -- included modified LK image
Of course, you could reflash by fastboot, no need to use SP flash tool.

hi if u have back up on your phone could u provide for me link. I had some problems with my loudspeaker and i thought its from the root, or software and i did full format and download. and now it show some watermark and probably is because i l deleted NVRAM.
i download already official version but didn't help ... thank u upfront.

Hi, I'm not rooted (yet) and my BV9800 PRO is having some issues with the loudspeaker, any media like YouTube or Spotify, play audio for a second or two and then just go mute, volume can be high but no audio at all, phone calls last longer but also go mute and have to go back to regular "ear-speaker" to keep listen to the other side. Are this the same problems you refer to? I can't remember if this happened after the OTA update tho. Thank you.
