Why can't we just unlock the bootloader and root with magisk? Patch boot image

I am fixing a phone where he did the abl file switch and it was stuck in a bootloop. So I went ahead and unlocked the bootloader. How do I flash firmware? Lgup is not allowing me to do so.

Do you guys think it would be possible to root a demo unit lg g8x thinq?

Thinking of getting a spare one for cheap and don't need celluar. I just want root and get rid of demo unit apps.

Would be bonus if it's possible to get imei working and/or custom rom onto it.
[LG G8 Guides, News, & Discussion] arbiter99:
dont need cellular but want imei working? does not compute. and demo units sometimes don't even have the cellular guts these days.
[LG G8 Guides, News, & Discussion] ENbuscaDEAprender:
I do NOT think it is possible on a lg G8s thinq demo retail, as it is not on android 9 and cannot be upgraded. I just want the storage and wifi, if possible the fingerprint sensor. Can't do anything with just the 4gb that is free.

If some genius would be encouraged to try them, they would earn the sky.

Damn, you're right about the demo units being on 9. I guess this isn't going to work.

Hello all :)

I followed all instructions and everything seemed perfect I'm unlocked with magisk root, then I tried to get into fastboot and now I get a error saying "no recovery partition". No matter what I do I can't get into the bootloader, from ADB, Magisk, plugged the phone in with the Vol- pressed. I tried searching around and can't find anything on it.

Also I get a screen about not being able to verify when I turn the phone on, I dont know if that has to do with DM verity.

Does anyone know what I might of did wrong and how to fix? thanks in advance! Sorry if I sound dumb.

Thanks for the detailed instructions on #3! I just had the same issue with my wife's G8 after she enabled secure startup, and I wasn't sure how to fix it. This helped a lot.

Cheers!
[LG G8 Guides, News, & Discussion] way2aware:
Yes. I did. I would suggest making sure that you've backed up your abl_a and abl_b files first, and that one of those files is only 1 mb in size (instaed of 32 mb). If so, then you're good. If not, you're still good, but your phone will list as a LG G8, and you'll have difficulty getting it to list as a LG V50thinQ again. If your software version is the '20d' Android 10, then I have the necessary abl_a and abl_b to get you back to the correct phone model, let me know.

Is anyone still replying to this thread?

I just bought the VZW LG G8 and followed this guide meticulously-- in using QFIL and loading the abl_a engineer file, after reboot it gets stuck on Verizon splash screen. I went back and loaded the abl_a and abl_b backup files, and after the 3rd try going back and forth trying other downloads I found of the 'abl_a engineer file', QFIL now gives me the error "Data Overflow, would you like to continue" If I hit yes it writes a abl_a file thats only 1,024 kb, maybe thats the engineer file that wasnt successfully restored with my backup.? It says it writes successfully. But the original abl_a back up was 32,768 kb. I tried erasing the data block first and it still gave Data Overflow error. My phone is basically bricked, but it will respond in QFIL as a Qualcomm QDLoader device.

Also this version of LG G8 Verizon doesnt let me boot to fastboot! They really locked this version down. I cant get it to recognize as a adb device either, but I did have success with QFIL!

When I bought it on ebay it was listed as VZW Unlocked, I was really hoping I could root it but its not looking good. If anyone has advice on how I could at least get it to turn on again I'd so appreciate it!! IT just buzzes every 10 seconds wth a black screen but it will connect it to QFIL.

If anyone can help me save this phone I just paid $150 for Id so appreciate it!!!!
[LG G8 Guides, News, & Discussion] durrant111:

It will go into fastboot mode if you install the engineering abl through EDL
[LG G8 Guides, News, & Discussion] armodons:
Successfully unlocked and rooted a LMG820QM!

Some issues that others may encounter:

1) Had trouble getting back into fastboot to flash the original abl_a and abl_b files; used QFIL to flash the files instead.

2) Had trouble with fastboot drivers on Windows 10. Had to update driver with the exclamation mark and manually choose LGE ADB Driver from the list.

3) QFIL worked initially, then when exiting Partition Manager would reset device back into EDL mode. Launching Partition Manager again would lead to Sahara error. Using the button combos to restart the device back into EDL mode would allow getting back into the partitions to read/load.

Also, for magisk root, since boot_a and boot_b are identical, I just flashed the magisk patched boot file to both slots.
[LG G8 Guides, News, & Discussion] rpbica:
Hi guys

Went to the part

"Do the same with abl_b, boot_a, and boot_b.

Boot_a and Boot_b is for Magisk Root"

After that, although it booted to EDL I was allways getting the message:

Download Fail:Sahara Fail:QSaharaServer Fail:Process fail

when I tried the next step, the load of the abl engineering file.

I have V500N20z.

Any help, please?

Thanks
[LG G8 Guides, News, & Discussion] armodons:
Try restarting the phone with buttons and get back into EDL.
[LG G8 Guides, News, & Discussion] rpbica:
It was in EDL because I could see the Qualcomm indicator in the Device Manager on Windows.

I'm afraid I'll brick my phone...
[LG G8 Guides, News, & Discussion] armodons:
You should always be able to use power button + volume down to restart. Repeat until you get back into EDL. From my experience with a LG G8, QFIL doesn't seem to like Firehose loaded twice and needs a restart of the device in between.

If you have LGUP setup you should always be able to get into download mode for a full flash into stock to try again from the beginning (assuming you don't start erasing things in QFIL).

It all went well until i had to boot into fastboot, then i had issues cos i cant find a method to get into the fastboot of

LG V50s (LMV510N) SKT version/region

i tried using vol- and pwr, and all the button combos that i found on google and no luck.

i tried using adb reboot fastboot, adb reboot bootloader, but those commands simply rebooted the device normally,

Does anyone know how to boot into fastboot on LG V510N(LMV510N) SKT version/region?

Am i missing something or is the SKT version of this phone completely locked in terms of fastboot?
[LG G8 Guides, News, & Discussion] armodons:
The abl file is what should enable fastboot mode. If after you have flashed it you're still not getting fastboot then it really might be your variant...

Hey everybody, I have an LG G8X (LMG850UM) from Sprint that had the G850UM20f software on it and I was able to unlock the bootloader (currently is unlocked) and install magisk and TWRP-3-1-1-0, but at some point something got cross configured. I think it was the DM verify part of TWPR because now my G8x is bricked. When I installed TWRP I had the encryption message and did a factory reset and wiped cache, but it would never load past the LG boot logo. I have a backup of my two original boot_a and boot_b images and as well as the magisk flashed ones and I have a kdz file of the 20f software.

Here is the tricky part. I was able to get past the frozen LG logo screen by using QFIL to load back the original boot_a and boot_b images. I can load the phone but my firmware is now running G820U21f on Sprint and it gets stuck with an android setup error saying the app crashed and it keeps crashing. I am able to mess with the settings and look around on the menu with an occasional android setup crash notification and am unable to click the build number to unlock developers mode. My next plan is to find a way to load into fastboot and try to flash the kdz this way. I tried LGUP and UPPERCUT but UPPERCUT crashes after establishing a connection to my phone and LGUP says it cant load the model .../model/common/LGUP_commo , and the pop up gets cut off.

I could use some help flashing this kdz to my phone and starting over but I'm scratching my head some finding out a way without LGUP tool or UPPERCUT.

Any help is appreciated!

I get to this part ...

Extract the ADB.zip

open a Command Prompt and change the directory to the adb folder you just extracted

cd C:\adb

run fastboot devices in that command prompt. it should show "LMG850UM fastboot"

Move the backed up abl_a.bin and abl_b.bin to the adb folder, also frp_verizon.img if you have the verizon LG G8.

...and I cannot get the frp_verizon.img to flash over. It says that there is not a file with that name.

Do I need to downgrade first?

Okay I got it this morning. Reread it still didn't understand but had some hunches so check around the net about LG dual sim unlocking and then it clicked. It was meant to say load the engineering file provided into both abl_a and abl_b

Hey after failed attempt to get Magisk working with lockscreen I tried the method of installing twrp. I managed to install the twrp, but touchscreen wouldnt work with twrp unless I hard reset the device. But even after hard reset, rebooting back to twrp will cause touchscreen not working again. Also I got a decryption issue with the twrp and 'solving' it causes me to bootloop. Btw I managed to fix both bootloops by recovering my boot_b in QFIL in case anybody had the same problem.

I had similar experience, it's just a lil tricky. I found it was easiest to boot phone completely, plug into computer, you hear the pc chime when phone is recognized, at that point hold the vol - and power until the pc chimes the disconnect, then immediately release the power button and tap the vol + repeatedly (usually 1-3 times) until the PC chimes connected, this all while still holding vol -. Practice how to hold the phone, release power and tap a few time and then it was easy.

Did you not format Data and then flash DM Verity in TWRP? Without DM Verity you would get an encryption error but you should still be able to use hardware buttons to get back into TWRP.

I have a G8 (not G8X) and Uppercut never worked for me. Your best bet is probably going to be try different versions or configs of LGUP to find one that works.

If you want to flash a KDZ but not use LGUP, I think that leaves only QFIL. So you would have to extract all the partitions from your KDZ and flash them one by one. But extracting a KDZ isn't that easy as none of the tools have been updated in a while...
[LG G8 Guides, News, & Discussion] spatial25:
Thanks for the reply!

I extracted the KDZ and got a DLL and dz and when extracting the dz I got various images that couldn't be downloaded because the kdz extraction tools DLL wasn't compatible with the g8x.

Anyways, I got LGUP to almost work and now I am getting a kdz error when trying to load the G850UM because the phone reads as G820UM. So I somehow have G8 firmware instead of G850UM. I read that there is potential to bypass LGUP locks but haven't found any. Do you know if its possible to load the G850UM back onto the phone?

I'm downloading the G820UM firmware and going to try to flash them when they're done downloading but I have slow internet.

Anyone have tips or suggestions?

Thanks!
[LG G8 Guides, News, & Discussion] armodons:
Sorry...I don't know enough about LGUP to know how it determines what the device model is. Did you flash something from G820UM at some point? Hopefully someone more knowledgeable can chime in...
[LG G8 Guides, News, & Discussion] spatial25:
No worries. I got LGUP to work but I can't seem to find a sprint US kdz for the g8x. The ones I could find are USC or something else. So I'm on the look out for a g850um or g820um sprint kdz now. I'm hoping someone sees this and links me to one.

I'm unlocked and rooted, but can't seem to get into fastboot. Has anyone successfully installed TWRP?

I was able to by downloading the TWRP 3-3-1 zip: https://xdaforums.com/t/unofficial-twrp-recovery-twrp-3-3-1-0.4201783/ and installing it with the magisk app: https://magiskmanager.com

Follow the unofficial twrp guide and be sure to disable DM-verify by installing it through twrp. I think I read that the magisk app has a disable verify in its advanced options that may work better than installing the zip though.

If you show on the adb devices and have developers options with USB debugging enabled then you can probably do adb reboot bootloader to get to fastboot.
[LG G8 Guides, News, & Discussion] Kievanightwing:
Hi! I'm currently attempting to unlock the bootloader and root my LM-G850UM.

I'm currently in fastboot at the step:

Extract the ADB.zip

open a Command Prompt and change the directory to the adb folder you just extracted

cd C:\adb

run fastboot devices in that command prompt. it should show "LMG850UM fastboot"

When I run fastboot devices, no devices are shown. I've installed all the drivers OP linked yet device manager at this time says there's no driver loaded for my phone.

I've attached a screenshot of my phone in what I believe to be fastboot mode as it looks just like the screenshot in the OP. I've also attached a screenshot of the device properties window of device manager showing the no driver loaded error. I'm afraid to reboot or do anything not mentioned in the guide as I do not want to brick it.

I'm just thankful QFIL worked just fine so if I need to I can load my backed up abl_a and abl_b files back on the device.

Any help would be greatly appreciated.

EDIT: I have solved my problem! Had to go in via devicemanager, tell it to update the driver, then select browse from files on my pc, then select pick from list, then from there I picked one of the Android device options and saw a driver for Android ADB. With that installed everything else worked properly.

Here is the TWRP: https://www.mediafire.com/folder/3kzmsjkz60gdb/TWRPG8

The folder has a magisk I would avoid installing because I think it has incompatability issues that bricked my phone. This TRWP had foreign characters but had english with them. There will be an encryption lock that the disable DM verify should get you past like in the TWRP forum: https://xdaforums.com/t/unofficial-twrp-recovery-twrp-3-3-1-0.4201783/

Remember to check the Magisk 23.0 app for the function that disables DM verify that could work better than installing the disable DM zip. Good luck!

I'm still looking for a Sprint US LG G8 .kdz, if anyone has one or has seen one, please link!
