Hello All.
I have TWRP installed on my Nexus 5 D820 device.
But averytime I try to boot into the recovery mode, I am getting the stock android recovery instead.
My device is rooted of course, my android version is 6.0.1.
How can I go to the TWRP screen?
Thank you!
Did you enable the System read only option?
System read only option: Devices that ship with 5.0 and higher as their initial OS are using block level OTA updates. With this style of OTA update, the update script checks to see if the system partition has ever been mounted read/write. Further, the script also usually runs an SHA sum of the entire system partition to detect if any changes have been made. If any changes have been made, the OTA update will refuse to install. Since not all OEMs and devices have factory images available, we have created a new feature in TWRP that detects if the system partition has ever been mounted read/write. If not, you will be prompted asking if you want TWRP to mount system as read/write. If you choose not to allow TWRP to mount as read/write, TWRP won’t prompt to install SuperSU and TWRP won’t try to patch the stock ROM to prevent TWRP from being replaced by stock recovery. The goal of this option is to hopefully allow the user to make a raw system image backup that they can use to get back to a state where they can take OTA updates again.

Thank you Primokorn.
No, I didn't enable this setting. I rooted my phone using NRT toolkit, which performed the root quite automatically.
Can I do it now somehow?
Remove .twrps (hidden) file into /sdcard/TWRP then install TWRP again (using fastboot would be better)
You should see this warning message at first boot. Swipe to allow modifications.

Well, I have managed to enter the TWRP screen using the fabulous Nexus Toolkit application.
It is a workaround - but at least it worked. I really asked me if to enable read only mode.
Welcome to this guide, where I will guide you through rooting, flashing custom roms, and more, on our little Umidigi One Max !
WARNING : I am not responsible for your phone breaking or exploding during the night under your pillow. Please advice. If you cannot boot anymore, keep reading, your phone is NOT dead.
OFFICIAL ROM (Android 8.1)
The Umidigi One Max comes with Android 8.1 Out of the Box. Manufacturer has no plan on having 9.0 on the phone. That's why we root then ! Let's get into it.
Rooting the phone without unlocking it, or installing TWRP
Everything you'll do on this phone will NOT require a bootloader unlock. Note that this method is only in case you don't want to have your data wiped, or don't have access to an SD card (thus you cannot flash .zip in TWRP, except for ADB Sideloads)
What you'll need
Download the latest ROM from Umidigi's website : https://community.umidigi.com/forum.php?mod=forumdisplay&fid=211
Choose the ".rar" file
"E" ROMs are for European versions. It doesn't really matter what you choose.
Download SP Flash Tool on the same thread you opened for the ROM. It's "SPFT" for short
Unzip both
Install Magisk Manager on your phone : https://github.com/topjohnwu/Magisk/releases/
Steps
IMAGE COURTESY OF bencebacsi @ Umidigi forums
In the unzipped ROM folder, find boot.img
Copy it to your phone storage using an USB cable or any other method
Open Magisk Manager, press install
Choose "patch boot image file"
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
Let magisk do it's job
Find the boot.img file you just copied
Copy the patched_boot.img back to your computer
Open SP Flash Tool
Open the "Download" tab
In "Scatter-loading file", press the folder icon and browse to the downloaded ROM folder. Choose the only file that shows up
Untick every box except for boot. There is a column called "Location" with a path, click on it to change to file.
Choose patched_boot.img
MAKE SURE YOU UNTICKED EVERYTHING EXCEPT BOOT
Click the "Download" button
Turn off your phone (not reboot) and connect is via USB
wait for the flash to succeed. Once done, unplug, boot, voila ! You got magisk !
Credits to topjohnwu for Magisk, what a great piece of work
Installing TWRP
Note that if you want to access the /data partition (internal storage), you'll have to wipe it ! If you do not need it, keep going, it won't wipe unless you want to.
What you'll need
Official TWRP recovery.img by chankruze : https://twrp.me/umidigi/onemax.html
Magisk.zip installer (NOT the manager) : https://github.com/topjohnwu/Magisk/releases/
SP Flash Tool : http://www.mediafire.com/file/wxlld9dfywk67jl/SP_Flash_Tool_v5.1916.rar/file
This method is shorter and requires less downloaded files.
Steps
Turn off your phone
Run SP Flash Tool
Load the scatter file (see pictures above) you downloaded from the latest ROM (see above as well)
Untick everything except recovery
Change path to recovery.img to be the TWRP image
Click "Download" and plug your phone
After it's done, unplug, and press Power + Vol Up
You'll see three options appearing. That's how you'll get to the recovery. Use Vol Up to scroll, and Vol Down to select. Choose Recovery Mode !
TWRP should boot by now
EXTRA STEP : Make /data readable. You will need to format data (YOU'LL LOSE ALL YOUR DATA) (Wipe > Format Data > Type "yes") and after that, flash this zip : https://androidfilehost.com/?fid=1322778262904004415
You can now proceed to flash zips, including Magisk.zip. If you made /data readable, you can send it to your internal storage. If not, use an SD CARD or ADB PUSH / SIDELOAD.
Returning to stock to fix issues / brick
Use SP Flash tool but instead of unticking everything, tick everything. Note that USERDATA, if ticked, will clear your data.
Ticking only certain partitions may work if you got issues with magisk or system mods and are still on Official ROM. Flashing boot and system will remove Magisk. If you are on custom ROM, you can flash their system again to fix issues as well. Make sure to choose the right system.img in SPFT !
OTHER ROMS
Installing GSI (Generic System Image) to get Android Pie 9.0
GSI takes advantage of Project Treble to create one system image that will work on most devices without issues due to a separate "vendor" partition. The One Max is Treble-compatible, but only up to 9.0 (No 10 Q for now)
This will allow you to get an AOSP experience, with it comes easy modding and theming, and less bugs, less chinese-spying (that's a thing apparently, but who cares really ? Not me to say the least)
GSI List
You can find a GSI List including bugs and download links in my other thread here : https://forum.xda-developers.com/android/development/gsi-gsi-experiments-t3941194
WARNING : DOWNLOAD GSIs WHICH ARE ARM64-AONLY AND NOT AB !
Installing a GSI
You will need TWRP Installed. Check above if it's not done yet. You'll also need the Magisk.zip, and I highly recommend you getting the disable-force-encryption zip
Start up by wiping /data in twrp (Wipe > Swipe the bar). It will not wipe the files in your internal storage (Music, Download, etc...). If you want to get access to /data in TWRP (which I highly recommend), you'll need to do a full format (Wipe > Format data > type yes).
Download a GSI (.img) and send it to your phone (Either using an SD Card, or adb push [file on computer] [destination folder]). Send Magisk and the disable-force-encryption zip at the same time.
Flash that system image using Install > Install Image > Browse to the .img file
Flash disable-force-encryption if you formatted /data (don't flash it if you didn't do that !)
Flash Magisk.zip
Reboot and profit !
Note that there might be some issues with the GSI you choose. Most GSI suffers issues regarding Wifi Tethering/Hotspot. Other than that, check for my thread for issues regarding GSIs.
Some GSI require installation of GAPPS (Google Apps). Download a GAPPS zip and flash it at : https://opengapps.org/ (Choose ARM64 and 9.0)
If Installation fails, saying that system size is too small, go to (Wipe > Advanced Format > Tick "System" > Repair or change file system > Resize File System) and try flashing again.
INTERESTING MODS FOR ALL ROMS
Magisk FDE.AI
A great system manager. Saves a ton of battery without a performance hit. You need magisk installed. XDA Thread : https://forum.xda-developers.com/apps/magisk/beta-feradroid-engine-v0-19-ultimate-t3284421
Fix SafetyNet not passing on custom ROMs/GSIs
SafetyNet will not pass by default on custom ROMs / GSIs.
Use Magisk Hide Prop Config : https://forum.xda-developers.com/apps/magisk/module-magiskhide-props-config-t3789228
Run 'su' then 'props' in a terminal emulator. Edit Device fingerprint, choose Pick a certified fingerprint. I recommend using Xiaomi Redmi Note 7, as it changes the status-bar to be notch sized.
Note that you may need to do this next fix to make 'su' work :
Root request not working with Magisk
On some GSIs, root requests will not show up. You need to move some vendor files over to system.
Use TWRP's File Manager (Advanced > File Manager) or Adb shell to copy theses files :
Code:
/vendor/lib/libdirect-coredump.so
COPIED TO
Code:
/system/lib/libdirect-coredump.so
Code:
/vendor/lib64/libdirect-coredump.so
COPIED TO
Code:
/system/lib64/libdirect-coredump.so
This will fix this issue until GSI / ROM creator fixes it in their ROM;
Enjoy your new phone ! Don't forget to say thanks to all the developers behind every project (not me ! I didn't do anything )
If you have any issues, feel free to ask questions !
See you on the other side
Downloaded phhusson's AOSP ROM
Extracted compressed image. Then...
Wiped Phone from TWRP w/ all three options Swipe, Formatted (Type "Yes"), and advanced wipe.
From TWRP went to:
Install > Install Image > Selected system-arm64-ab-gapp-su.img > Select Partition to flash image
From this screen it lists these partitions for selection:
-recovery
-nvram
-uboot
-boot
-logo
-tee
-System Image
I select System image. It starts flashing. After it has finished, I go to reboot, and that is when TWRP states "No OS installed".
Am I downloading the wrong image file?
*********************EDIT****************************
Nevermind. I downloaded system-arm64-aonly-gapps-su.img.xz and it boots fine with gapps included
Exactly, you downloaded A/B image, not A-only.
Using phhusson's AOSP ROM. I got the root requests show up. However the superuser app is blank. Nothing shows in the list.
Request for a video to install GSI
Hello
I'm using Umidigi One Max Android 8.1 and want to upgrade to 9.0 . Can you please make a YouTube video showing how to install the GSI version I'd gladly appreciate it.
Over the last month or so, I've tried multiple GSI ROMs, and stock. I've rooted stock, and everything runs nicely, I just can't stand the lack of features. Even rooted on stock, Google Pay still works. If I install a GSI ROM like Havok, root it, gpay will not work. Not sure why it works on stock rooted with magisk, but not with other ROMs.
I'm looking for a hacked stock rom for the one max that:
A.) Can be rooted.
B.) Can still run gpay.
C.) Has a advanced restart option to boot directly into recovery.
D.) Displays the battery in the status bar as a percentage rather a symbol, and a clock with seconds option.
If I had those options, I would stick with stock. I can accomplish all those options with Havoc GSI ROM, I just can't get NFC/gpay to work.

how did you repair su binsaries after flasing (in twrp the vendor folder is empty)
everything else works
@ _cab13_
thanks for tutorial
some comments/questions
Image shows MT6739 in phone image and scatter file of mt6739
My phone is MT6363 and appears to agree with online specs site such as
https://www.gsmarena.com/_umidigi_one_max-9525.php
Am I looking at the wrong tutorial or umm have you grabbed images from another phone and forgot to say so?

You have to mount the folder system and vendor for reading and writing and you can copy it, this is in recovery mount
Very helpfull, thanks)
Has anyone tried dual SIM and SD hack on this phone? I cant get my to work. When I do the hack, phone does not see any sim cards nor SD card.
However if I put only two sims, or sim and SD everything works well.
It is almost like issue w Samsung but no warning message
can i use this process on umidigi one as well
q1. Can i use this process on umidigi one as well?
When i visit "Official TWRP recovery.img by chankruze : https://twrp.me/umidigi/onemax.html" and search on devices they don't have umidigi one or one pro only the one max option. Other than screen size all three are pretty much spec'd the same. The umidigi one just doesn't have wireless charging or nfc that one pro and one max have and one max has 6.3 waterdrop vs one/one pro 5.9 notch display but all 720x1520 9:19 aspect ratio configurations. I found a umidigi one and one pro twrp recovery image here _https://unofficialtwrp.com/umidigi-one-umidigi-one-pro-root-twrp-recovery/ so if i have that are all the other downloads for doing non-rooted device upgrade to 9 pie non-device specific downloads?
q2. Nice to see this process covers a way to get form 8.1 to 9 w/o rooting device. Having never done so i'm curious why other search hits cover steps that require rooting device if the upgrade can be achieved without doing that, any insights?
q3. Would you say the likelyhood of bricking my device, if trying to follow these instructions using umidigi one vs one max, very low? Trying to determine if i should first line up and have on hand backup phone to use if the chance of that happening is high.
does magisk install allow me to upgrade to android 9 pie?
does magisk install allow me to upgrade to android 9 pie from the default android 8.1 oreo on my umidigi one or do i have to use the twrp recovery setup option to enable installing gsi arrowos or pixel experience android 9 pie update?

Yes, with the single installation of magisk you could upgrade to Android 9, but you would have many more functions through TWRP. how to remove encryption, backup, etc.

Thanks for reply. I was trying to see android 9 pie in magisk modules listings reviewed elsewhere and wasn't seeing what looked like a full android 9 install but rather options that themed and existing android 8.1 like android 9.
q1. If i complete the spft application of magisk_patched.img version of boot.img and try the android 9 module update option that's a one way street correct?
q2. Can one disable magish_patched.img version of boot.img by using spft to put the oem boot.img back in place?
q3. Sounds like twrp is the best way to put the official pixel experience android 9 [ or 10 ] custom rom on my umidigi one device. Your article shows how to get twrp enabled without bootloader unlocking the device. Any insights as to why there are so many articles suggesting that you have to bootloader unlock device to get twrp custom recovery image installed?

Magisik, is used so that android 9 can boot, (now 10), in the system update to android 9, you only update the System partition, everything else remains as the manufacturer installed it, when you install twrp, you only change the partition recovery, and when you install magisk you change the boot partition, all this can be reversed, if you install the original versions.

just to clarify, with the magisik patched boot.img i'm then able to apply a module that enables access to android 9 [ or 10 ] in the system update UI at which point i will carry out a standard issue android 8.1 to 9 [ or 10 ] upgrade process vs twrp where it appears you directly apply a gis custom rom like the mainstream pixel experience or arrowos options?

No, there is no custom rom, which can be installed from the system update, all are images of the system partition, which are called GSI, which are installed by means of fastboot, or by twrp, all of them can be found here: https://github.com/phhusson/treble_experimentations/wiki/Generic-System-Image-(GSI)-list

interested in what makes a gsi [ generic system image ] custom rom an official vs an unofficial image given the pixel experience is listed as unofficial and aosp, arrowos and resurrectionremix offerings i've seen referenced in many places are listed as official.
i'd like to try the only official android 10 q aosp listing on my umidigi one to get off the dated android 8.1 experience and onto the more current one. This article suggests i can get twrp onto my device without bootloader unlocking it and with ability to revert back to the factory oem image setup currently running on it, if that update causes me to loose functionality or stability, using twrp recovery.
Is that a correct interpretation of the instructions in this article, and your clarifications in our exchange? I'm interested in experimenting but would like to not loose ability to go back to non-bootloader unlocked factory oem image in the event i need to exercise device hardware warranty or sell it. Thanks for your clarifications and additional insights.

You can return, to the Originate flashing state, this image, https://community.umidigi.com/forum.php?mod=viewthread&tid=18692&extra=page=1 , can experiment with any image and return it to the original state, the pixel experience does not work with this phone, in Android Q the NFC does not work, and the videos in whastapp, do not work. Android 10 image comes without gapps, you have to flash them. If the twrp you can flash it through fastboot
