instructions:
boot to EDL
use the prog_ufs_firehose_sm8150_lge.elf for programmer file
select tools > partition manager
flash the magisk patched to both boot_a and boot_b

this is my first time using QFIL to unlock bootloader and root, if you have any problems, please reply back

I highly suggest people to make their own Magisk boot file using the Magisk app, as the last couple of times I used someone else's Magisk file, the Camera app broke, audio wasn't working at all, and I think my Phone froze a couple of times.

It's been a while since rooting with 20j, Android 10.
Phone has been sitting in a box, now I wish to use it for my car as a media/ navigation device. The g7 I use now is worn 😂

I was wondering if the Android 11 releases, 40a would be rootable in the same way.

Here's the firmware list, click to sort by date.

    looks like your device is not a 20e firmware (audio not work,cant make a call ,ui crash) i will help you to root just share the boot_a img (stock)

    Hello,

    I have the exact same issues. Didn't notice the Indian variant on Magisk in the Root guide, and ended up with an unusable phone.

    You say boot_a image stock, do you mean from before the whole process? I unfortunately didn't back up this particular partition..

    Boot.zip contains the boot.img file pulled from the kdz of the US G850 20b.I don't know if this is useful, but I got it...

    ReadData_.ufs_Lun4_...... is the boot_a file pulled from my phone after I turned it into a buggy mess 😅 I also don't know if this helps, but I do need help getting my phone working again if you'd be so kind. This is NOT the boot_b flashed as boot_a like mentioned in the video.

    The one you provided was not help ,Give me the stock boot_a img (download the whole kdz and extract the boot_a.img)

    use this
    Thank you, here is the boot_a.img


    EDIT: I have potentially good news! I was completely stuck in a boot loop, but using the files from the KDZ (modem_a, modem_b, boot_a,boot_b, abl_a, and abl_b) and pushed them each with fastboot. The device restarted (with sound!) and it is resetting to stock now. We'll see what happens!
