I'm going to try and encapsulate everything that's going on into this initial thread but I'm sure I'll miss something.
Basically, I undertook to root my phone last night. I followed all the steps in the root thread, and I thought it worked, but then when I went to the root checker to see if I was successful. The test couldn't get a result the first time, and then failed the second time. I've known my phone to be a little temperamental when it comes to stuff like that, so I shrugged it off. Then, everything started running with so much lag that my only option was a reboot. It came back up just fine, but then, apps wouldn't open anymore. Since a reboot fixes everything, I rebooted AGAIN... except no I didn't, because I couldn't move past the white splash screen.
After some time hacking around with TWRP, system restoring my phone and the like, I finally managed to actually load the OS again. I think the phone was rooted at that time, but I don't know for sure, because this was the drawback: I couldn't install ANYTHING. My idea is that the system was rebooted into read-only mode. I tried everything I could think of to revert the system to rewriteable again, but nothing ever panned out. There was just one thing that stood out to me: "Your phone worked properly when it wasn't rooted." So, I got the brilliant idea to use SuperSU to unroot my phone. Stupid, stupid move, because now my phone can't boot past the white splash screen again. As a last ditch effort, I decided that it was time to flash the stock system to the phone. Except I probably did it wrong.
Code:
fastboot flash recovery recovery.img
Code:
fastboot flash recovery system.img
Code:
fastboot flash recovery boot.img
And where I stand now is that my phone will not boot past the white splash screen, and I can no longer access either TWRP or Fastboot.
Is my phone fooked, or can anyone save this?
#1 You can't flash system image via fastboot - it's semi-locked.
#2 You can't use 'flash recovery' command for boot and system images.
#3 For restoring your phone use SP Flash Tool - there's a thread in the General section called 'How to unbrick'.
Try it and let us know.
Cheers
Yeah, I realized afterward that if I were trying to flash the image of the system, I should not have used the "flash recovery" command because I disabled access to the other recoveries, lol. I have tried to use the SP Flash Tool in the past few days, but I could never get any download progress. I think my computer isn't making the VCOM drivers accessible to be able to flash those things to my phone. Do you have any advice on that end? Because I have seen that thread and tried those steps but I'm just not successful.
You should also read all replies to this thread - there are people who solved their problems with SPFT in their own way, that's how I've revived my phone from hardbrick.
Make sure you're phone is disconnected when you start the flash. AFTER you hit the download button in SPFT... then connect your phone...
Fantastic advice from both of you. I'm ready to revive my phone!
Okay, I think I'm making good progress on recovering my phone. I have managed to get back the stock recovery onto my phone, which I then used to install TWRP. But I'm not out of the woods yet. I used fastboot to flash the boot image onto my phone also, but when it came to the system image, I'm having a lot of trouble. The only ROM I can find for the Blu Pure XL is a 7z file. Now, I know how those work, I have 7zip and I extracted it for the system image. When fastboot was available to me, I couldn't push the system image to the phone. Now that I have TWRP and I have no more access to fastboot, I've tried to load the system file onto my phone through my SD card in four different ways:
As a .img file
As a .7z file
As a .zip file that I created by zipping up the image file
As a .zip file that was .7z, but I changed the extension
None of those methods worked. The Blu development thread doesn't point me to a zipped ROM file. One person there said that they had a backup of their files and provided a link, but those images seem to have been removed.
I'm so close, I can see this phone working again in the near future, I just need your help to get me there. Please! :'(
Edit: Also, keep in mind, I'm dumb. I don't think I really did anything super wrong, but I may be missing something ultra obvious. So if you could just keep your answers dumb for me, it would help even more.
I would stop trying to use all of the methods you are using I believe you are slightly confused by them at this time..
At this point what you have done with the random image flashing is get damaged partitions..
Get SPFT. Turn off you phone completely.
Download the full Scatter file for you phone. (put it aside).
Download a file called ALL MTK driver install. ( or something to that effect). Search for it on Google. You will find it. Run it and then reboot your PC completely.. (if you have windows 8 or higher look online on how to install unsigned drivers) --THIS IS THR BIGGEST PROBLEM PEOPLE HAVE--
Extract your full downloaded scatter image to a directory.. (you can download the Gionee E8 image if you want) it is what I am running on my Blu..
Run SPFD read the thread that they pointed out to you. Find the scatter and point SPFD.. Once it is loaded on the program UNCHECK the PRELOADER check box.. (if not you can cause problems) ..
click download and after 10 seconds or so plug in (you completely powered off) phone into the computer..
.Then wait..... and wait... It will tell you it's progress..
Keep trying it, it WILL work.. and ALWAYS unchecked preloaded when flashing with spdf...
I did follow all the steps in the original guide, and I followed the steps that you gave me too, down to using the advanced device manager to remove any MediaTek drivers from the computer and restarting the computer with disabling the driver signature verification, but when I click download, wait, and plug my phone into the computer, just nothing happens. The computer says it's an unrecognized device, and the download never progresses.
I see also that you said keep trying, but every time I try the SPFT, it never sends anything to my phone. And I don't even know how to tell if I'm missing some important step.
OK this happens sometimes. plug the phone in with device manager open.. plug the phone in when it is off..
When it says unrecognized device double click on it really fast( it will disappear fast, try it a couple of times if you don't get it the first time) then hit update driver.. point it to the MTK drivers folder (unzip the MTK drivers folder). It will pick the proper driver. on some computers it loads up so fast it has no time to recognize the driver..
After you load the drivers power off your phone again and follow the instruction I gave.. After you do this once it will load the drivers right after this..
When I double click on the unrecognized device button, it just brings up a notification that my device wasn't recognized because it malfunctioned. I don't have an option to install any drivers.
My problem is finally solved. After starting up SPFT and clicking download, I held Vol - and Power and then connected it, and that pushed the download forward. I got to the Blu animation screen, and it stayed up FOREVER, but then the next time I looked over, it was on the initial setup screen. Good as new.
Thank you guys for all your help. This forum really is an amazing place.
Disclamer: Okay. This is my first XDA post so, it might be a bit shabby.
I am writing this post because it caused me a day of my life in reviving my dead Lenovo A369i. I broke my galaxy S5 so had to use this old buddy. Well, it got jacked while flashing it through the SF Tool as it accidentally (or as my hand was paining and i shook the USB cable to place in on the table - accidentally though) disconnected the phone while it was in the middle of an ongoing flash.
So, there it went, whole day of blood boil and headache.
Anyway, cutting to the point, if you have the following issues:
Bricked your phone while flashing via the SF Tool or bricked it doing something else.
Lost your IMEI [INVALID IMEI] after flashing or lost it anyway.
Your phone is showing no signs of life, even when connecting to the charger.
SF Tool gives Error 4032. Failed to read DRAM.
[/LIST
...then this is the solution you can try. At least one solution, the one that worked with me.
THIS SECTION IS FOR UNBRICK-ING YOUR PHONE IN CASE ITS DEAD. TO SOLVE IMEI, SCROLL BELOW
Things you should have before proceeding:
A Lenovo a369i phone (or any MTK devices that has the described issue).
Compatible MTK drivers.
Charged phone. Charge it for at least an hour. Your don't want to mess this up. I kinda did. It isn't mandatory but why the extra risk?
The stock ROM. Now, this is the most crucial requirement. With me, i had to download a bunch of ROMs before i got the one that matched my phone. There are two variants of A369i: The 'lite' and the non-lite (i don't know how else to put it). I had the lite variant and i didn't knew that. It took me 6 hours to understand the difference. Anyway, you should check yours and proceed. This is the lite 4.2.2 stock ROM.
Once you have all the things ready, follow ahead:
Extract the ROM somewhere. Navigate to the 'flash_tool.exe'. Run it.
Select the 'Scatter-loading' option, go to target_bin folder or wherever you have extracted the firmware and select the 'MTXXXX_Android_scatter.txt'. This will load all the files for flashing.
Now, here is where it gets a li'l tricky. I prefer to format clean the phone before flashing the rom. This helps avoid any interruptions. But it also wipes the user data. This is not mandatory but you should do it in this way.
Click the 'Format' button. Turn your phone off if it isn't. Squeeze the volume UP and Volume Down keys together and connect the USB to your computer. Your phone will get detected and your will see the bar at the bottom of the flash tool turning red and then green notifying that the format is complete. If you have any issue like the phone isn't detected, then you need to reinstall the drivers. This step is mandatory. If your drivers aren't installing properly, turn off the DIGITAL SIGNATURE ENFORCEMENT (you can search google how to) and install the drivers.
Once the format is done, remove the battery. Wait for a few sec. Fidget with the power button if you like, because i do. Then put the battery right back in and repeat the same steps as before but click the 'Download' button instead.
Then squeeze volume up and down >> Connect the USB to the phone. And wait till the tool completes flashing. And do take care you don't disconnect it. If you do, you might have to come back here again. LOL
Once its complete, you will be notified by a green notification. You can go ahead, disconnect your phone, remove the battery, fidget again, put it back up and boot your phone. Luckily, it might start.
IMEI INVALID SOLUTION
If you are as lucky as me, you might get this issue. Well, do not worry. You are not alone. And this might be just the solution for you.
You need to download a bunch of files and do a few steps. Here's what you need:
You need to root your phone. Framaroot worked for me.
If this doesn't work, you can try KingRoot app for rooting.
MTK DROID Tools for replacing your IMEI back to what is was. androidmtk.com/download-mtk-droid-tool"
The steps:
BEFORE YOU START, REMOVE YOUR BATTERY AND COPY BOTH YOUR IMEI SOMEWHERE. YOU WILL NEED THEM.
Root your phone. Open Framaroot and select any from the two options. You should get a success message if rooted. If not, install KingRoot application. You will need internet connection to root with KingRoot.
Once rooted, you need to open the MTK DROID Tool. Before connecting your phone to your computer, you need to enable 'USB Debugging' from the developers option. To do that go to Settings>>About>>Status>>Click Build Number for a few time>>go back>>Developers Option>>Enable it>>USB Debugging. Now connect your phone.
At the bottom right corner, you will find a ROOT option. Click it. It allows the tool to gain root access to your phone. It will pop up to install some app like supersu, mobileuncle tools and root explorer. You should install them. Also, you can backup your phone (This is optional).
Now click the IMEI/NVRAM type both your IMEI and click 'Replace IMEI.' Restart your phone. And that's it.
You have successfully revived your dead phone/Replaced your original IMEIs/Conquered the WORLD (well, for the moment ).
Cheers. :good:
done.
hi,
this is a guide for real helpless people, that got a V20 H918 T-Mobile out of the box and have no idea
what to do, to get TWRP and root. and since on this phone its a REAL hard odyssee if youre not a pro,
and you dont want to spend days and weeks to pick up countless small puzzlepieces to finally get all together up and running, i decided to write this guide. im no pro myself, but with countless hours of reading and try and error, misery, headaches and brainpain, i managed to get this thing running all right with working downloadmode,
newest TWRP-version and 20H oreo 8.0
so far, everything seems working good. ill play around with this version and if i encounter some crap, i will edit this guide later. sadly most "newbie-guides" here, are from pros for advanced users with decent knowledge. so when u start from zero, you dont understand half of what is written. thats why i will keep this guide as simple as possible, with some side explanations. its a lot to read and a lot to do, but this way works!
what we have before starting:
a V20 H918 t-mobile 20H oreo 8.0 with bootloader locked. simply a crippled standard phone.
what we will have after this guide:
a V20 H918 t-mobile 20H oreo 8.0 rooted, with unlocked bootloader, working downloadmode,
and newest TWRP-version.
with twrp u can backup your whole system "as it is", means u fukk up your phone, simply go to twrp-recovery, restore your backup and you have your phone up and running 100% as before all went down the drain. simply and easy. just like a new installation of win10, but in 5 minutes. u can flash custom roms, kernels etc., install all kind of stuff, no need to pay for apps anymore, get rid of obnoxious bloatware, just 100% freedom and the full potential with the V20 (which is the last phone of its kind with exchangable battery, which is why i got myself 3pcs of it )
sidenote: get yourself some extra protection foils so u can change from time to time.
also get yourself 1 or 2 10000mah powerbatterys from aliexpress (perfine) with protective rubbercase, of course, they dont have the printed-on mah, but at least a considerable amount, so that your phone will last at least 3-6 days. my V10 lastet 11 days normal usage with zerolemon powerbattery. unfortunately, these retards refuse to send to europe, and as far as i know, theyre not producing for LG phones anymore, so aliexpress/perfine is whats left.
the rubbercase gives the phone a superior protection, adds a serious amount of weight and will stick in your hand like glue. it is by far less likely to drop out of your hand like these glass-phones for imbeciles. and if it drops, the rubbercase grants excellent protection. my V10 dropped countless times, still working perfect.
but lets get to the guide now.
at first, we will unlock the bootloader. without it, you wont be able to do anything.
unfortunately, LG produces great phones (with great audio!) but terrorizes the users with their strict anti-root attitude. it seems it gets harder everytime to root and unlock the bootloader. i remember back in the days old samsung devices, had been rooted in no time. this one here cost me about 2 weeks.
on this phone, u simply cant hook it up to the pc, and unlock the bootloader with adb. it will be recognized by the pc, but as soon as u enter fastboot, nothing will happen, no command works.
the solution is a FWUL (forget windows use linux) usb-bootstick, with that u boot your
pc into a custom linux (i think) only here u have full access to your phone via fastboot and can unlock the bootloader in no time. it will not work on win10 !
- first, get rufus, a win10 tool, with that u can create boot-usb-sticks.
https://rufus.akeo.ie/
- then get the linux FWUL image (only 15GB version is still up)
https://androidfilehost.com/?w=files&flid=214529
- unzip the linux image to your c drive or your desktop.
- start rufus and select your usb-stick (it should be 30gb+ in size)
be carefull not to chose any other drive or stick (it will get erased completely), better double check.
- select the image you just unziped. (i use 7zip for unzipping)
- leave all other options as they are, press start. when dialog-box pops up, chose DD-mode !
- now waste some time, as it takes a long time to create the bootstick (in my case about 30min)
- when the stick is ready, in my case it couldnt be recognized anymore in win10, its just a raw-drive, that cant be
opened. thats allright. dont worry
- now close down all applications running and insert the created bootstick. (at this time u might consider using a
separate laptop, so you can follow this guide here at pc and use the laptop with linux running, thats what i did)
restart your pc, hit F2 or F8 oder DEL or whatever to enter bios.
select the created stick as bootpriority nr1. so that the system will use this stick as
the first bootmedium to boot from.
- u get to a screen with 9 bootoptions to chose from. chose the first one. it should now boot into linux.
when password request pops up, enter: linux
- u reach the "desktop"
connect your LG V20 H918 20H via usb-c to the pc, which has linux running, make sure that
developer options are unlocked, OEM-unlock and USB-debugging is enabled and u chose picture transfer protocol
(PTP) as transfer-protocol (also in developer options). if PTP doesnt work, try media transfer protocol.
watch your V20, at some point it will ask for confirmation of connection , click OK.
in linux, click on the up-arrow in the most downleft corner and chose "terminal emulator", which is
a pendant to windows shell/command-line.
- here you can execute the adb commands.
first, check if your V20 has been recognized by your pc with linux running.
type: adb devices
it should appear a message like:
* daemon started successfully *
LGH9182bfblablabla device
that means, that your V20 has been recognized correctly. now you can reboot it in fastboot mode.
type: adb reboot bootloader
your V20 screen goes black and seconds after, it restarts in bootloader mode ready for unlocking.
you might get a red warning that your warranty is void if bootloader is unlocked. cool.
type: fastboot oem unlock
wait for response, your bootloader is now unlocked.
u can check by typing: fastboot getvar unlocked
it should say: yes.
the bootloader is now unlocked.
now we will replace the standard recovery with twrp on the phone.
this step will be a little confusing and complicate, just follow the steps, and it will work.
since we cant flash twrp with adb, we have to use the linux bootstick again.
but before, we have to downgrade the 20H version to 10P, bcuz the next stepp will not work with 20H !
so you get the following:
DOWNLOAD H91810P KDZ FILE
https://androidfilehost.com/?w=files&flid=282709
after that, download LGUP (the LG tool for downgrading from 20H to 10P)
and uppercut (dont know what uppercut is for, i just used it instead of running LGUP directly and it worked. its supposed to recognize the phone/driver automatically)
http://downloads.codefi.re/autoprime...sh_Tools/LGUP/
and download the recent LG-usb drivers.
http://tool.cdn.gdms.lge.com/dn/down...=UW00120120425
install LGUP, uppercut and usb-drivers.
connect ur phone to pc in download mode.
turn of phone, press and hold vol.UP button and connect usb cable, small message appears, phone is now in download-mode and waiting.
now run uppercut and hope, that ur phone will be recognized. if not, think about, what kind of restrictions u did to ur system, like OnO-shutup or xpantispy (both great programs to keep win10 from calling home to scum gates) or whatever. in my case, it ONLY worked, after i reset the OnOshutup settings to recommended. so the phone get recognized correctly in LGUP (if not, try laptop or different pc), select upgrade and select the downloaded 10p KDZ file. press start or go, and wait until the procedure is finished.
now your phone is downgraded to 10p.
now we go back to linux, we connect the phone in downloadmode with the pc/laptop where linux is running,
(turn phone off, hold volUP, connect usb-c-cable with linux-pc/laptop, phone will start in download-mode.)
make sure, your laptop/pc has internetaccess.
on the linux-desktop, click on the LG folder, inside, click on LGLAF runningnaked.
a terminal-window opens.
type: git pull
type: git checkout h918-miscwrte
type: ./step1.sh
now we have flashed twrp onto downloadmode. why? i dont know, thats the way it worked for me.
we dont want twrp onto downloadmode, since twrp is a recovery. so the next step is, to flash the newest twrp version for H918 to recovery. at first, we will gather all neccessary downloads, after that, we will flash them one by one. that way, you dont have to get your micro-sd card out of your phone again and again. we put all together on the card, put the card in your phone and we are almost done. for now, have your micro-sdcard connected
with your pc and download the following:
twrp-3.4.0-1-h918.img
from
https://dl.twrp.me/h918/twrp-3.4.0-1-h918.img.html
and put this .img file on micro-sd card.
then download (and put on sd-card):
MAGISK ZIP DOWNLOAD (for root)
https://github.com/topjohnwu/Magisk/...gisk-v16.0.zip
then download original 20H firmware(and put on sd-card)
H918 20H
https://androidfilehost.com/?fid=11410963190603864639
you remember, we have now twrp on downloadmode
for restoring download-mode, download (keep on desktop or c):
H91820h_00_1115.kdz
https://lg-firmwares.com/downloads-file/17076/H91820h_00_1115
then download the firmware extractor:
https://forum.xda-developers.com/attachment.php?attachmentid=3975633&d=1482337024
ok, lets see what we have now:
we have the phone bootloader unlocked and twrp on downloadmode. we can access twrp when we start the phone in downloadmode (hold volUP, and connect usbcable, phone will start now in twrp.)
we dont want twrp on downloadmode, we want twrp as recovery. and we want to restore the original downloadmode. for that we do the following:
unfortunately, the neccessary file for flashing orignal downloadmode is not online anymore, so we have to extract it from the 20H firmware with the firmware extractor (thanks to logical gamer for his guide)
https://forum.xda-developers.com/v20/how-to/guide-h918-restore-laf-partition-t3804728
Extract WindowsLGFirmwareExtract vx.x.x.x. to your desktop, and open it up (preferably in it's own folder).
u might have to install framework 3.5 for it to run.
Select Open across from KDZ/TOT file, and browse to your KDZ (H91820h_00_1115.kdz)
you download previously and double click.
After it loads the kdz check H91820h00.dz, and click Extract KDZ.
Close and re open the program this time Click open across from DZ File in the folder where you placed WindowsLGFirmwareExtract you should see a file called H91820h00.dz Double click to open it.
Check laf_6.bin then click Extract DZ.
put this laf_6.bin on your micro-sdcard. thats your original downloadmode we will flash now.
ok, now we have our micro-sdcard with twrp, magisk, laf_6.bin and H91820h.zip.
put this mirco-sdcard in your phone. start the phone in downloadmode.
it will start in an older twrp-version. in twrp, go to install and select install img
select the twrp 3.4.0.1. img and on the following screen select "recovery"
swipe
this will flash the 3.4.0.1 version of twrp onto recovery.
then go to reboot into recovery. it will now boot into the newly flashed recovery.
then go to wipe, advanced, and select everything EXCEPT micro-sdcard!
this will totally wipe your phone (except twrp), so u can flash the 20H firmware onto a clean phone.
then, go to install, select H91820h.zip. this will flash your original oreo 8.0 firmware.
after that, go to reboot into recovery.
go to install, select magisk. install.
this will root your phone.
after that, reboot into recovery, go to install, select install img, select the laf_6.bin, and select "download"
now the original downloadmode has been restored.
now you can reboot into system, your phone will start as on day1, with new twrp on recovery and root.
i did a complete backup in twrp, so i can get back to a day0 clean install whenever needed. i will do a second backup with twrp with all the stuff installed and working ok and place this on my sd-card. so when things go bad, i always can go back to this state in no time.
congrats, your done. and me too . gonna get a cold one now.
hope this guide will help someone. in case, just drop a like/thanks/or just a short note.
its a long guide, and im no pro, if i made some mistake pls. tell here and i will correct.
thx to all the pro-guys for helping the helpless.
Hi
Im on v20 H918 firmware 10p with bootloader unlocked.
I tried with dirty cow but not works with lafsploit i have a Problem with rufus for create a bootable Linux.
Pendrive is 32 GB i followed your setting but my PC boot only in windows 7.
I succesfully unlocked a h990ds with dirty santa but for this model is not supported.
Can you help me
hi
i tried with dirtycow also, didnt work.
thats why i eventually came to the method i described.
teling by your short description, your next step would be to create a bootable linux-usb-stick, and to find a pc where it will boot correctly. the stick didnt boot on my main pc ( i dont know why, it just canceled with an error),
thats why i had to use the laptop where it worked.
Thanks for the guide man! Very funny and fun to read. I can't wait to turn mine into a 4-day brick like yours. #lastphonewithbatteryrevolution
Sadly I got the dreaded encrypted error at the end though when booting. Everything else worked fine.
After the encrypted error though I formatted and flashed LineageOS 17.1 and then magisk and still keep getting error 1. Even tried Lineage recovery and still same. I think maybe a problem with Magisk 16 itself.
Anyway it works fine just no root.
Edit: Had to flash Magisk 21 and it worked
Thanks for this tutorial. I was able to get my V20 rooted with minimal trouble. The only major trouble was finding a computer that will fully boot into Linux and the only minor issue was locating the UPPERCUT but I was able to find it. Link below.
It's probably worth mentioning that I had to rename laf_6.bin to laf_6.img in order to flash it in TWRP. Also, at the time of writing, the latest version of Magisk is 22.0 but I used Magisk v21.4 instead because it had a zip file (Magisk-v21.4.zip) available for download so that I can flash it via TWRP. Link below.

cool, glad this guide helped at least a little bit. my v20 still works great, no issues so far. as a side phone for unwanted persons, i still use my v10 with powerakku and rubbercase "brickstyle" every time i hold a regular phone from other people, it feels weird since these phones weigh like nothing, and i have to focus not to slip it out of my hand. i love my bricks
and by now, about 4 month later, reading this whole guide, to me its still strange and hard to follow. there is no way to get through this without reading everything possible about it and become familiar with all the technical terms.
I have a h918 with an unlocked bootloader and it's downgraded to 10p. The shell script fails everytime to a hash check. I've run it 4 separate times with the hashes being the same every time. So it looks like the file has been updated but the hash hasn't.
I'm coming late to the game and it seems most of the guides are out of date. I'd appreciate any help I can get.
Update: It works fine. This is by far the easiest guide to follow that I've found. Many thanks! I did have to follow xstahsie's tip.

I followed the guide after I rooted and installed Lineage OS 18.1. I had to remove LineageOS because it was bad with response, couldn't see hidden wifi, and just ran hot. So I followed your guide and I am in a logo bootloop and get the reminder to lock the bootloader everytime it starts. Any suggestions for getting past the bootloop?
I fixed problem by installing LAF you referenced and then LGUP to 10p kdz. However I noticed two things.
1) Whenever I boot up I have the nag message to my bootloader. Any way to address this?
2) If I try to follow steps above to install 20h, I get a decrypt message in TWRP after I flash 20h and before Magisk. Anyone see this? I didn't encrypt my storage before hand.

You're stuck with it, it's just the way it will be from now on.

I don't remember seeing that. I probably didn't care if it did show up since it was a new install from scratch anyway.
Does encrypting the phone work after following this guide?
hey there, cant help u with the encryption thing cuz thats far beyond my knowledge. some weeks ago my phone dropped, and a tiny crack on the edge appeared. what i didnt know was that this crack is the beginning of the end of the V20. heres the story short: small crack over time leads to a bigger crack, bigger crack multiplies and u have some more cracks covering the whole screen. also the screen can pop off and hanging loose a little. in my case 4-6 weeks and i have to get out phone 2/3 which i am setting up using this guide now. fortunately i left myself a huge pyle of information on how to do this when starting at 0. over time u forget EVERYTHING u have done, so having these infos is hammering.
lucky me did i save my internal memory of phone 1/3 bcuz 30min later the screen was totally fuqqed up, no access no chance of backupping internal memory.
so heres my recommendation:
DONT drop your phone. even in my case with rubber battery case from aliexpress
(perfine "10000"mah) a 50cm drop cracked the edge of the screen. if that happens, backup your internal memory !!! (just do this on a regular base)
when ur screen gets damaged and u cant enter information or cant see anything anymore on the screen ur internal data is lost. so always have ur internal memory backuped!
and great job LG for producing such a huge pyle of ****. one small drop, screen cracked, bravo, last time i ever bought anything from lg. my V10 dropped like a 1000times, nothing, still up and running. v20, drop, 6weeks later, dead. thanks LG the customers all over the world couldnt wait to use these bull**** crackable glass-screens. great job, -1 customer.
I've tried this on two different computers with two different cables in every USB port on the machines but can't get by the Windows portion. I am using UPPERCUT as the windows box/LGUP reports no device found without it...
Of course UPPERCUT drives windows security mad as it's reported as doing bad things but as I'm using an extra win laptop that will be wiped I disable all of that....
I have three different sourced KDZ files as the one linked wasn't initially reporting any mirrors. Eventually a mirror did pop up for it but by then I had downloaded two others -- all were the same size and one of the three reported from LGUP was bad. Every attempt with the other two failed. Invalid Command response came up a few times... sometimes it just failed at around 80+ percent from the PC side which was 99% on the phone's downloader mode progress bar.
It's very frustrating.... I would like to blame windows but there seem to me plenty here with success... any other ideas?
Also... since it got so far, rebooting at this point just goes to the download mode so I might be hosed... I can force it to the fastboot mode and it is still unlocked so I've been trying to install TWRP onto recovery using the linux/android machine but when I type
fastboot flash recovery twrp.img from the directory where twrp was downloaded I get this:
sending recovery --- okay
writing recovery --- failed remote: unknown command
So... any thoughts?
aloha, at which step are u stuck exactly? did u make your phone being recognized by the win10 pc?
one thing to regard is, that a usb-CHARGING cable possibly wont work, u need a designated media/data-cable.
i had this situation before, where using many different usb cables drove me insane bcuz i simply couldnt establish a proper data connection with phone/pc, it just didnt work. it took me many hours until i realized, that all of the cables i tried were charging cables!
for me the most difficult step was having the phone being recognized by the win-pc, the rest went relatively easy.

The phone is recognized by the PC, no problem. I do have to use UPPERCUT to get LGUP to recognize it though. The step I'm stuck at is applying the downgrade. It gets to various percentages of done-ness and fails. It got far enough that now my only options on the phone are Download mode or fastboot mode. Problem is, I can't seem to get anything to push to recovery so I assume that it's still not properly downgraded.
I've tried a few different cables and keep in mind the cable I used in the linux adb bootloader step worked fine. I don't entirely know what difference there is between a charging and data cable but I do know the main differences in the steps are a> Windows and b> size of transfer.
weird. since im no pro myself, my ideas are limited on this one. there might be some kind of loose contact at the charging port,
that when the phone is moved just a little it looses connection for a second and reconnects again, had that in the past, so try not to touch the phone at all. did u use the 10p kdz file mentioned before? did u make sure it has been downloaded correctly?
if an error occured and there are some % missing... its like faulty ram, hard to detect.
assuming, u did or did not downgrade to 10p, did u try to continue with the linux-step? ---->
---------------------------
on the linux-desktop, click on the LG folder, inside, click on LGLAF runningnaked.
a terminal-window opens.
type: git pull
type: git checkout h918-miscwrte
type: ./step1.sh
now we have flashed twrp onto downloadmode
-----------------------------
maybe uppercut/lgup displayed an error message for no reason, and the downgrade itself went through without a problem in the background.
pcs sometimes do weird things.
if nothing works, try setting up win10 and try on a virgin system. in my case, OnOshutup prevented win10 from recognizing the phone,
or try using a 3rd pc from a friend.
i was able to setup my phone 2/3 using this guide in 30min, no problems at all. (i hope i wrote down, how i solved that simlock issue.....)
no matter what causes the problemin ur case , id be interested to hear what it was.
Thanks! Rooted and Unlocked thanks to this guide!
I tried following other guides using UPPERCUT and it fails to downgrade due to Anti Roll Back. How does this relate to this guide since the last thing I want is for (by design) for it to brick the phone. I have yet to find anything specific saying an unlocked bootloader will bypass the anti rollback check.
Hi As a noob does this keep VoLTE? I have followed this guide and backgrade to 10p was perfect! VoLTE working on a phone that was "new" from china. VoLTE did not work on the 20p rom it had. Also does anyone prefer Phoenix591's h918-20g-prerooted rom to the stock one? I have read a lot but am somewhat confused by varying instruction threads. I want to use this as a daily driver. Thanks
Anyone have this problem and solved it? I have an ASUS Zenfone Max Plus M1 (ZB570TL ) - (X018D) and i have tried every Rom you can think of from WW to CTC to CN, also tried dump firmware but nothing will stick and let this device actually fully boot up after flashing it, it just goes to the POWERED BY ANDROID screen and after 30 secs it will reboot itself back to the POWERED BY ANDROID screen and then reboot again and so on..
HOLDING VOL+ and POWER buttons in gets me to the:
- RECOVERY MODE - Just reboots back to Powered by Android screen and back to bootloop, no android guy recovery...
- FASTBOOT - Lets me have Fastboot but i cant flash anything or unlock bootloader as it errors and shows its Locked...
- NORMAL BOOT - Just reboots back to the Powered by Android and then reboots after 30 secs right back there....
There is no RECOVERY MODE that i can Factory Reset, Update.zip, clear cache...
I Flashed with SP Flashtool over 20 Firmwares and all finish with the popup Finished and green checkmark and i watch the flash process all the way without error, unplug the device and turn it on and back to Powered by Android screen and reboots itself after 30 secs... THIS IS CRAZY its like its a GAG Phone or something just messing with me like ( Jokes on you big guy ) ive never seen anything like it, its like the locked bootloader is telling the device not to allow any Firmware to install by tricking the SP Flashtool that yes it did install but didnt allow it to write to the actual system or let you get into recovery mode to factory reset the device or update from sdcard... im just wondering if its a waste of time to bother finding a UFI Box flasher that doesnt need the dongle so i could try flashing the EMMC files if that would help or not... its not a hardware problem or it wouldnt accept flashing or let it power on and enter fastboot mode....
Is this a GAG Device or has anyone actually had this exact problem and has solved it? If i could just get it to boot up into the system i could use Magisk and make a patched-boot.img thats unlocked bootloader and root but theres no ZenUI or anything but the Powered by Android screen....
Any Help would be awesome as i just put new screen, battery, back cover and buttons on this device thinking it would be a good little phone for my daughter... i cant even get any info on the device as theres no box or sticker with IMEI or Serial Number or info on the last working Firmware its all a shot in the dark... Anyways if anyone has the way to get this device working or has backup rom or links to an actual way thats not ASUS as they are just waste of time for 30 mins then you need to take it in to our service center and pay more money and im done putting money in this and could have bought her a new phone for what ive got into this Gag Phone....
Thankz...... Kixx
Judging from the whole situation, you screwed up several things honestly.
The fact it goes stuck on the splash screen and refuses to neither boot on recovery nor the system itself seems to tell 2 things:
the boot.img and recovery.img got screwed up way too much- or literally got flashed for the wrong device, hence the whole rejection to boot;
i assume SP Flashtool, even if got tricked, got a bit of a mess on the internal partitions to be flashed thru. Sounds like a big red flag because ADB can be highly of help (i don't own an X01BD but an X00HD- still an asus device- but i used simple ADB instead of things like QFIL or SP Flashtool to get things going);
On second point, if you wanna try to unlock the bootloader (since fastboot is the only one to be alive and usable- this means your device will be salvageable...atleast by a significant chunk):
you can give it an attempt by checking over my own collection post.
There you will find at the bottom some tiny guide on how to unlock the bootloader-
if you don't have a secondary rooted device, you can always rely using a laptop or pc.
What really matters is that you'll have ADB downloaded on your machine, because it could be of help to progress thru with the stuff.
After unlocked the bootloader, you can slowly approach to flash TWRP for your own device- even tho, it seems nobody so far has done anything for this specific model...
Atleast, on the bright side, unlocking the bootloader will give you the chance to flash manually the partitions via ADB, and maybe the official zendesk site for it can help if unpacking one of the update zips and see the contents inside- or generally pushing the following .zip update file via ADB and wait for the magic to happen.
I'm not sure on how to help with the region tho.
I guess, if you have the box of the device, it could give you a clue if it is a WW (WorldWide), CN (China), JP (Japan), etc. model- afterall, these letters do not lay around without a reason.
Of course, if you flash the wrong region to the wrong regional model:
then the recovery and system partitions get to screw up big time, just like the scenario you're having right now.
As a last thing, the patched boot.img file only gets to work after you got android to work-
otherwise, patching the pre-rooted boot.img file will be of no use since a functioning ROM isn't there at all.
Sadly, i don't own the device nor never had such screw-ups of this kind, but i hope it will help you up.
Ya i can flash the firmware correctly in SP Flashtool it comes back with green checkmark, all the firmware is for the correct device, its just when i had it given to me it had broken screen and bad battery, so i buy new screen, battery, backcover for it and when i booted it up it just sticks on the first screen shown ( Powered by Android ) then after like 30 secs it reboots back to that screen.. I can hold the vol + and power and get the menu to pick RECOVERY or FASTBOOT or REBOOT, recovery just reboots to powered by android screen then reboots after 30 secs, fastboot lets me use adb and fastboot but cant flash it says failed locked, and fastboot oen unlock or any of the commands to do with unlocking or flashing just gets me failed locked, but fastboot does work. Only way to root or unlock bootloader the device needs full boot into system so i can enable adb debugging or usb debug in developer settings so the computer will let the device get past the failed error locked part....
Do you know how to get the usb debugging turned on so the computer can grant full access to the device then il be able to actually crack into it and flash through fastboot..
Or where the usb debugging file is in the system.img if i extract it, use text editor and give the bool a yes that its been accepted then repack the system,img and flash it usinh sp flashtools, then i might ge able yo get it up and running....
After flashing all kinds of firmware for this device they all pass the flashing except for a few of them, ones that dont work wont even let the device boot to show system thing, then flashing correct firmware it allows the first screen again and the menu to pick fastboot but wont fully boot up..
Im thinking there must be somekind of lock the device put on from letting you oem unlock bootloader or booting into recovery mode because the firmware is working or it wouldnt take it using SP Flash Tools or even let it boot up as it would either reboot instantly or not even turn on, if the boot partition or recovery partition was courupt or broken or damaged it wouldnt take it during the flashing process it would fail....
If you know how i can activate the usb in developer settings from a file in system.img file after ectracting it then thats prob my BEST OPTION OR BUY A USED MOTHERBOATD OFF EBAY...
Lol

Well, as far as i can tell and did unlock 2 asus devices of the same model (still, X00HD):
i didn't needed to go thru android, since Asus never had an "OEM Unlock" thing to enable once unlocked dev settings-
yet, i'm speaking about the X00HD since, again, i never owned an X01BD, but i am trying to apply the same reasoning even if it is an entire different model but still same brand.
Dunno, in my case i was able to get the bootloader unlocked by going getvar all and got the secret key to unlock it just as easily by experimenting and finding cmds to use over this device's forum in here while being in Fastboot mode.
Before stepping my feet to Fastboot, tho, i even tried to get my hands at an OEM Unlocker apk made by Asus:
but to no avail it only worked on devices with really old firmware and since my device was updated to the latest Oreo FW, it was impossible to perform since things got patched overtime.
Sadly, i really don't know how to modify values over system.img files myself and tick up variables by inspecting over hex editors and such.
Least i know is getting the Brotli binaries and some other specific tool on GitHub to extract stuff from Android .img files, but that's all my skills really get limited to since i'm no dev myself nor either someone who can reverse engineer things just as well.
I think you could be out of luck on that regard.
Only thing that remains is going to a particular mode where it is required putting the phone apart and touch 2 specific pins on the board to enter it.
I currently forgot the name of this mode, but i do know by fact it's a common thing between Huawei devices.
If even this thingie won't help, then i really dunno myself.
Maybe someone else could be of help instead of me lol.
Ya ill try touching the two pins but what two oins and touch them with whst? Give me a roll out on what to do, i just dont understand why it accepts firmware but wont let me boot up into it or recovery mode or flash anything because at first it flashes then when it completes it fails and says remote unknown locked
Also im going to try find a way to format or partition the main system partitions maybe the system.img is landing on a different section of the harddrive... just need tge partitions for thus device

Aight, to start with: i'll share out a couple of links.
First, here's a picture on where the testpoints of the device are.
As of second, you need some tweezers or something that is able to touch such testpoints inside the board (unrelated, but the GH page to PotatoNV has a guide what to do with the testpoints- even tho, the page redirects you to a tool that only works with Huawei devices. Don't test it on that asus device.).
Not sure about the flashing tool, honestly, but i do know for a fact i couldn't share software in here due to rules of this forum.
Since this is, i suppose, a device with a Qualcomm SoC:
maybe you could use stuff like QFIL Flash Tool for the job (dunno about partitions, for that you should get some linux knowledge- since android uses the linux kernel to communicate with everything inside the device).
Also, i've got something intriguing right now:
apparently the forum for the X01BD effectively exists over XDA lol (turns out the X01BD is a Zenfone Max Plus M2 and not an M1).
Maybe you can check out here for further custom ROMs and recoveries, plus more proper help on the matter- as of firmware dumps, you could try hopping over Android FileHost, firmware.mobi, or steep your feet into some unknown forum that has the firmware dumps of this specific device and restore it logically (or simply doing a google search by doing [insert model number here] firmware dump - if google only gets you to shady sites, stick to the XDA forum on the device).
