Failed Android 7.1.2 install on LG V500 - stuck on boot screen

Question

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?

Answer

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
