oh well it would have saved some time to know your model number earlier!!

You have the same as me, the sprint files should work just fine then.

Here is the 7.5GB download it's all I can say to do,

g820um20d.zip

drive.google.com

This has all the Sprint Image files for android 9. If you want to start over from android 10 just let your phone update over the air

(but I doubt your going to get an android 10 root that works as well as the android 9 one does)

otherwise just do what I did from android 9:

Open phone in EDL mode in QFIL,

Go to the partition manager.

Start from the top and flash anything that matches from the g820um20d folder to the phone.

So if it says abl_a flash abl_a from the folder and so on. This will take awhile for the bigger files there's about 4 huge ones, the rest of the files will be pretty quick. You will not use all the files in the folder, there are many the phone will not have the names of, so just skip them.

If it goes to a password screen just boot into recovery and factory reset it, after that it boots.

When you are done, boot phone, and continue to magisk install and use the boot_b file from g820um20d folder which is what you have just flashed. I followed the instruct also to do this without a microsd card in the phone, move the file to the internal storage.

Once you run magisk on your phone and patch the boot_b image,

reboot again into EDL and flash the patched image from QFIL, I was able to do this from QFIL and it worked it did not require fastboot.

The phone will now be rooted with magisk.

It is possible to get into EDL mode in a bootloop. It is just VERY annoying. Sometimes I had to reboot like 3 times, basically sometimes it maybe rebooting and still showing the pause boot warning screen, so it takes 8 seconds for the phone to reboot press vol down and power and count to 8, hopefully it won't be on the warning bootloader unlocked screen, it maybe rebooting and still showing that is my guess. But immediately at the moment the screen goes black start pressing the vol up key while still holding vol - and power.

It helps to have QFIL open as it will show up when it connects.

I bootlooped my phone two times before deciding to just go ahead and flash everything in this download since I really really wanted my phone rooted.

It may also help to unplug the usb - from both ends - and then plug it back in to ensure a fresh connection.

It eventually will go into EDL mode if you try but each time the phone boots you MUST release all keys, go ahead and let it reboot itself once so you get a fresh new try and then press vol down and power again, you may also want to try at different times as it may reboot before the full 8 seconds so wait let it reboot and immediately press the two keys so it will be under your command not in the bootloop.

What is 20I ? If you flashed that image to the system you should be on android 9.

software version says G820U10I <- is that what your talking about?

When you reboot your phone do not connect to Wifi or any network, your phone will update it's software online if you do. You have to set your phone up not to do any updates before setting anything up or you get an OTA update.

Did you connect to any network?

Once android 9 boots your ready to patch the boot_b with magisk and root your phone from the second part of the guide same as from the very beginning. I start by unlocking developer options and unchecking the update on reboot, and enable usb debugging,

On android 9 --->1 settings 2 general 3 about phone 4 software info 5 click build number

then go to

-> Settings

->Update LG Software

-> click on three dots on right and goto settings and uncheck both check for updates and auto updates.

At that point you can go online and the phone will not update itself.

Once the phone is rooted you can go on to install shortcut master lite and add your APN, I use H20 Wireless on my Sprint G8 :D

After I flashed it my phone went back to blinking. So I put it into download mode and tried the LG mobile support app and it said my phone was up to date with g820um20i which was what I was already on. I don't understand its like my phone is blocking everything I try on it.

Ahh, I see. That is unusual. Well can you please then put the engineering Abl_a onto slots abl_a and Abl_b then boot the phone into fastboot to confirm you are on slot B

MAYBE I forgot I did this,

But it could make a difference, in fastboot once you have confirmed fastboot devices,

The command should be

fastboot flashing unlock <- this is the basic flash unlock command but not for all partitions

---

Edit I just ran fastboot - help -- To help me remember!! -- and there it is You Might need to remove the underscores I am not sure because fastboot -help does show them...

fastboot flashing unlock_critical <- this should allow flashing Everything!

And this command I did not know .. until just now but you can also

flashing get_unlock_ability <- This line should return the status of flashing lock

and ensure you're on slot b

fastboot --set-active=b

This may be neccessary to tell your device to allow flashing to the partition tables according to some, although lgup maybe telling you that because it switched to slot a.

if it does not boot after restoring abl_a and abl_b you will probably have to flash again since no flashing occured but should be unlocked now, otherwise it only switched to slot A.

When you are successful it should bring you to a password screen, that's when you'll reboot into recovery and factory reset.

NOTE: Engineering abl_a must be flashed to get to fastboot but will not boot phone.

Abl_ & B must be restored to boot normally but NO Fastboot.

I'm going to go watch John Wick now... :D

Use the kdz file from here https://lg-firmwares.com/downloads-file/24295/G820UM20i_00_VZW_US_OP_1124 and use the one - click kdz extractor to extract the files.

Hi to all, I need help with my Thinq G8x G85ßEMW with 10 V20d-eea-xx.

I unlocked bootloader, installed magisk via boot_a and boot_b and all was fine for 3 weeks.

Now I made a reboot and i am stuck at the LG logo, which is spinning.

I can press "power" + "volDwn" and it restarts but always stuck at LG logo.

I also can enter EDL mode sucessfully and start the partition manager.

I reflashed abl_a and abl_b and also BootA and BootB, but I still have a spinning LG " Life´s Good".

What can I do ?

Maybe it did an ota update without my knowledge? I was on 10d when I did all the unlocking.

UPdate1:

When flashing the original boot_a and boot_b phone boots again.

I then patched via magisk (20005) the both img files and reflashed them via QFIL but then I have again the boot stuck in LG Logo.

So it seems as soon as I use the magisk boot files I can not boot anymore.

Maybe a bug with magisk 20005?

Update2:

Also with the initial 22.0 apk Magisk and Patching I can not get it to boot past the LG Logo again.

I do have to patch boot_a and boot_b, right ?

I also just patched boot_b and flashed with qfil but still no joy.

Any ideas to use magisk again?

Hi, my phone is Lg V50 Sprint, I rooted it and used for about 3 weeks, yesterday I did a reboot and got bootloop.

But since reflash abl_a abl_b boot_a boot_b won't work, I don't know what to do next. (in the 3 weeks rooted using, I was remove some bloatware using luckypatcher, maybe that cause my problem.)

reflash abl engineering file and check your active slot. In my case, It went from slot a to slot b. Repatch your active slot boot file by magisk manager (boot_b.bin in my case).
[LG G8 Guides, News, & Discussion] AlmanGP:
I did it but I was unsuccessful

I put the abl_a file back on abl_a and abl_b

then i looked and i was in fastboot "Active A/B Slot - _b"

then reboot the system open Magisk hit "Install" then "Select and Patch a File" and select the boot_b.bin

I Reboot to EDL

Open QFIL

on boot_b flash magisk_patched.img

reboot and only enter on fastboot

I put the original boot_b and reboot normal

I also tried putting the original abl_a and abl_b first and it remains rebooting in loop

Does anyone know of a root explorer that works with LG phones, allows read/write not just read
[LG G8 Guides, News, & Discussion] luffyacekun:
the screen that you can see active slot is engineering abl file. after flash it using qfil there are two options:

1. hold volume - and power (it will take time, your phone will reboot from 9008 mode) when device manager on windows show that your phone is disconnected, release power button, still keep holding volume down, you can get into fastboot.

2. if the first method doen't work, try to power off then plug usb cable while holding volume down button. (this one always works for me)

[LG G8 Guides, News, & Discussion] mangojain:
Thanks, i tried this procedure earlier and failed and i had given up, but on reading your post i gave it another shot yesterday on my 820TM and everything worked at the end.

The main points i want to list, for the benefit of others -

1. Fastboot works only once, after you flash the engg abl. After unlocking the bootloader, when you flash back abl_a and abl_b, fastboot mode will stop working again

2. When trying to go into TWRP through the key combination, your phone may go only into the stock recovery. Don't worry, choose the option to erase all and continue, it will take finally take you into TWRP after a couple of iterations

3. To get VoLTE working on your 820TM on non T-Mobile networks, you essentially need to modify the cust.prop, apns.xml and vo_config.xml files.

It feels great to finally crack the VoLTE issue and get it working on the 820TM in India.

Unfortunately, i have not been able to replicate the procedure on my 820QM7 (unlocked version). For some reason, TWRP fails to decrypt the internal storage. I have tried everything that i could find on the Net, but nothing has worked. It seems that there is nothing to do but wait for a working TWRP3.5 for the Pie branch to come along. If anyone has any advice on the topic, it is welcome. I have kept the QM7 with Magisk installed, looking at the files mentioned above (cust.prop, apns.xml and vo_config.xml) which just need a slight modification, but can't edit the files :-(
