I had CWM Recovery and an older cyanogenmod rom installed on my LG G Pag 8.3 (V500) and I wanted to upgrade to 7.1.2 from here: https://forum.xda-developers.com/lg-...8-r16-t3476750

I copied the ROM to internal memory, rebooted into recovery, selected the rom file to install. It showed some messages about patching, then in a couple of minuted erred with smth like "Erro loki-ifying because of incompatible aboot image".

I then rebooted and now it boots and shows "ANDROID" and is stuck on it - looks like it partially updated the ROM and failed somewhere.

I am not sure what to do now - I tried to boot into recovery (Power off -> Hold Power + Vol down till menu shows) but it doesnt work - it keeps booting onto this stuck boot.

Is there a way to fix it or have I just finally bricked it?

Solved it by downloading LG Mobile Support Tool, switching the tableto into download mode (Power Off, then press both Up and Down vlume until it shows download mode), then connecting the USB and after the LG Mobile Support tool recognizes the tablet, go to Options -> Upgrade Recovery. The tool will download and flash the latest stock image. After that I got stuck on boot loop and performed factory reset:

  • Press and hold Power Button + Volume Down
  • When the LG logo shows up, release the power button only
  • Now press and hold the Power and Volume Up button while keeping your hold on the Volume Down button
  • When the factory reset screen appears, release your hold on all buttons
  • Follow On Screen Indications

Now I get a fully stock tablet that I can root, install custom recovery etc

  • As side note, I was never able to successfully flash the "pure" ROM from that xda-developer page I posted in the question. I ended up flashing the latest LineageOS and the tablet works perfectly now – Andrey Aug 13 '17 at 9:27

The answer you posted only got your tablet to working state, but LOS still isn't installed.

To actually install LOS, first make sure your stock OS is at least Android 4.4, then install TWRP recovery (since CWM is long dead) according to the instruction on the page (fastboot installation is heavily recommended), and finally flash LOS itself.

  • @iBug You used this to auto-insert the "site rules" comments I saw you posted? Nice touch. – Andy Yan Aug 5 '17 at 15:44
  • Yes. Exactly! (I will delete these OT comments tomorrow). – iBug Aug 5 '17 at 15:45
  • Indeed, this was recommended to me by people on MSE. A few 10kers and mods are using it. – iBug Aug 5 '17 at 15:46
