*update in cause someone is wondering you can keep the v50 eng boot abl_a/abl_b but touch screen wont work, so flashing stock backup of your abl_a abl_b is a must.

do we have to flash back the stock abl A/B or can we just keep the custom abl A/B?

[LG G8 Guides, News, & Discussion] adtamez:
Hello, I need help. I have an LG G9 Tmobile and was able to unlock bootloader and rooted with qfil. But then I went to install twpr through magisk and once I restarted I couldn't get to bootloader or fastboot or edl only to TWRP. So I went and did a hard reset but now I am stuck on a TWRP bootloop. I cannot enter edl nor boot loader no system. TWRP states there is no OS!

Please help. What can I do?
[LG G8 Guides, News, & Discussion] blaze2051:
might have to look into getting LGUP 1.14 and looking up your stock rom .kdz format and flash your phone again

try this website https://lg-firmwares.com/lg-lmg820tm-firmwares/ get it and boot into download mode flash, you need to get lg drivers too
[LG G8 Guides, News, & Discussion] adtamez:
Thank you so much! that's what i dis. I actually needed LGUP 1.16 with a different LGcommon.dll that I found for LGUP v1.17 in order to LGUP stop crashing and proceedfalshing.

So now I can use my phone, however I still don't have a bootloader, it just boots directly to system. Any advice on how to get the bootloader or fastboot working again? I have already flashed the phone several times and I changed slot from b to a. Before all this I try restoring boot_b.bin but didn't work.

Any advice?
[LG G8 Guides, News, & Discussion] adtamez:
Do you think I can root the phone again? What risk do I have of getting an update and messing my phone again?
[LG G8 Guides, News, & Discussion] xurena:
Hello.

I have LG G8X Sprint LG850UM running firmware 20i. I just unlocked bootloader and root it via magisk. Successfully done. And the phone can boot and run normal. But the phone now no sound at all, and if i try to boot it to "download mode", the screen only stay for 1 second and then it loads "fastboot" page. I cannot make it stay in download mode.

Look back, I think i messed up when making backup of abl_a abl_b boot_a boot_b modemst1 modemst2 using QFIL, It turned out that QFIL fails to read data when I made those backup, so the backup file is half baked.

Anyone know how to fix no sound problem after this unlock and root on G8X sprint?
[LG G8 Guides, News, & Discussion] xurena:
fixed : by my friend's g8x backup partition and flashed 20e OPEN CA. Phone now got sound. Only problem now IMEI and S/N is 0. But it ok, at least the phone isn't a brick / paper weight.

hello.

i did the first steps and now my v50s (korean) shows LM-G850N on about phone screen.

i have to unlock the bootloader now, but when i type "fastboot devices" at CMD my device doens't appear. i am using windows 11 and the version that shows on about phone is "G850N40f".

any help?
[LG G8 Guides, News, & Discussion] RenardHCRc:
before everything. Now activate USB debugging, check that you are not using PowerShell, the other may be that you are not starting EDL mode correctly, the other may be the Qualcomm drivers, try to reinstall Fastboot Recovery and as another option you can try to try another cable ( some usually do not work for that type of connection).
[LG G8 Guides, News, & Discussion] xpedro:
thanks for the help. tested all this but still nothing works. i think it must be the driver, but i've tried all the ones i could find, and it still doesn't appear when i run fastboot devices.
[LG G8 Guides, News, & Discussion] RenardHCRc:
What if you try typing "adb fastboot devices"?
[LG G8 Guides, News, & Discussion] RenardHCRc:
Just a question when starting Edl mode ends up with a black screen or with text on the screen?
[LG G8 Guides, News, & Discussion] xpedro:
black screen. i managed to use fastboot, and unlocked the bootloader. i was missing a driver that i found on xda. now i have to pass the patched magisk boot img, but qfil stopped working. i think i'll have to revert the drivers now lol.
[LG G8 Guides, News, & Discussion] RenardHCRc:
good. little by little. I struggled a little with my Velvet but in the end it's possible 👍🏻
[LG G8 Guides, News, & Discussion] xpedro:
this is so annoying. i managed to unlock the bootloader of my v50s (korean), but now i can't get into fastboot mode to verify which partition i am using, and besides that i can't make qfil work again (sahara error). is there a different method to enter fastboot mode after unlocking the bootloader?
[LG G8 Guides, News, & Discussion] RenardHCRc:
When it was my turn on the LG Velvet (845) I couldn't get back into fastboot mode. I did it by reaping. As for the partitions, I did it on both now, as for modifying the boot.ing file with magisk, only do it on one in my case on "A" because if you do it on both, the OS tends to crash (closing applications , and a lot of lags).

There is also a command by "CMD" that allows you to see the status of the bootloader, and in the system "activate OEM unlock" appears disabled (it does not allow modification). Try to back up all the files you modify. and the error that appears "Sahara" in my case I had to reinstall drivers and restart the PC. Also the phone restarts and I try until the PC recognizes it as 9008.
[LG G8 Guides, News, & Discussion] xpedro:
now i am rooted, but still can't figure out how to get into fastboot mode to flash lineageos. did you manage to get into fastboot after unlocking bootloader and rooting?
[LG G8 Guides, News, & Discussion] RenardHCRc:
If you can't with the key combination, try from "CMD" with the command "Fastboot boot recovery ×××.img" You have to do this when the screen is black 9008. You can also try with "Fastboot Flash recovery ×× ×.img" but that replaces the original recovery so I recommend making a backup. On LG it is sometimes difficult to enter the custom recovery so concmd is the fastest method. This is what I do with my: Mi mix 2s, Mi 11 and previously the LG V50.

On the V50 there was a key combination to start the custom recovery. . . . I'm going to investigate again to see if I can find it since I had it years ago.

Write the engineering abl_a and abl_b back to the device in Qfil and reboot!That will give you access to fastboot mode.
[LG G8 Guides, News, & Discussion] xpedro:
won't this make me lose root access? lineageos instructions says the device needs to be rooted in order to install the rom.
[LG G8 Guides, News, & Discussion] xpedro:
when i try the commands above in the black 9008 mode it says

"waiting for any device" and nothing happens
[LG G8 Guides, News, & Discussion] Surgemanxx:
Good possibility!The procedure is write engineering abl_a and abl_b first.Unlock the bootloader via fast boot.Then do the root procedure as normal with the boot_a and boot_ b file writes.Reboot the device.You should still have fastboot and root in place.It's the same as the LG V60 procedure since the file system is practically the same.
[LG G8 Guides, News, & Discussion] xpedro:
the problem is that after i unlocked the bootloader i was not able to access fastboot anymore, so i can't flash lineageos. is there any way to make fastboot work again?
[LG G8 Guides, News, & Discussion] Surgemanxx:
Yes,flash the engineering abl file to abl_a and abl_b.That will restore fastboot!
[LG G8 Guides, News, & Discussion] xpedro:
hey, man. i finally managed to flash lineageos and it seems to work pretty well. thank you very much for your help.

is your device v50s 5g too? i was wondering if it would be possible to unlock the other 5g bands, as it seems to work only on the band used in korea.

[LG G8 Guides, News, & Discussion] Blade2005:
So i screwed up. the instructions say to load abl engineering file and do it for both abl_a and_b.bin, so I assumed this meant the ones that I had just created, not the one abl_a file I had oringinally downloaded because that didn't have an abl_b variant. Why it didn't just say to use the original abl_a you downloaded is beyond me, at no point had it called that file the engineering file in any context. Anyways, now I'm stuck on the LGV50 menu with no way to load into the OS and I can only get into recovery mode. I tried a factory reset/wipe but that came with a permission denied message. Did i brick my phone completely or is there still a way to salvage this and try again now that I know to use the originally DLed file and not the created ones. I can still get into recovery mode and when trying EDL mode, it takes me to a firmware updater download mode. Any help would be greatly appreciated.

hello, this is the first time I've heard of a telecom operator blocking the bootloader. As far as I know, the lg company must send you a code to unlock the bootloader; this code can be sent to you by e-mail mil... on WhatsApp if you have it or on your phone number you can install another SIM card and try for a new one, ask for a code from lg on the Internet, there are many ways to unlock the bootloader, read carefully

View attachment 6112336

Still I have one doubt do I need to change the modified abl.bin file with the backed up on. Will there be an issue if I'm using the modified one in future updates?
[LG G8 Guides, News, & Discussion] Незнакомец 777:
good day Samir_008 if the firmware is compatible with your version of android then you can install this firmware it is not advisable to install android 12 on version android 13 or 14 you need to install on 10 or 11 androids to avoid problems if the firmware is compatible with your device then flash it but do not forget to make a backup copy your firmware just in case and the bootloader must be unlocked!
[LG G8 Guides, News, & Discussion] Незнакомец 777:
if you have a modification on abl.bin when you update your phone, the modification of this file disappears and becomes like a normal file, even in the mod application the update is disabled if you do not reset the modifications in the application and your file will be normal if you want to leave the modification on your phone then you You should not update your device without modification in the future

you have to install LG drivers or if needed install Android usb drivers
[LG G8 Guides, News, & Discussion] WAleedAHmaD:
if you want to root you devices.you have to use qfil.

1. Make a backup of "boot A" and "boot B" file then store them to a safe place.

2. then copy them into your phone's storage and patch them using magisk.

3. then flash patched boot a file into boot a

and boot b file in boot b using qfil.

4. congratulations your phone is rooted.
