[G Pad 8.3 General] larroy:
Hi

I was finally able to root my device, install TWRP on it and install lineageOS.

The methods that I found before don't fully work due to the latest firmware versions, but I found a way around it. You can find the necessary files in a zip file. Unfortunately I have few posts so I can't post links... is there a way to post a link to the zip file?

The file is in dropbox with path:

dropbox.com/s/s1vcd8z3c2chf4o/v500.zip?dl=0

unzip and follow the commands described in root.sh they are a bit succint but it worked for me.

Afterwards, just use TWRP to flash the lineageos image + gapps

The commands that I executed are:

adb reboot recovery

# Sideload kk_root.zip

adb push twrp-3.1.1-0-v500.img /sdcard/

adb push ./aboot.img /sdcard/flash_tmp/aboot.img

adb push ./recovery.lok /sdcard/flash_tmp/recovery.lok

dd if=/sdcard/flash_tmp/aboot.img of=/dev/block/platform/msm_sdcc.1/by-name/aboot

dd if=/sdcard/flash_tmp/recovery.lok of=/dev/block/platform/msm_sdcc.1/by-name/recovery
