What works
Downstream kernel compile, Telnet iniramfs works to fix a partition issue (pmboostrap install selects wrong partition UUID), then process freeze later.
What does not work
How to enter flash mode
Factory reset/enter recovery
LG default recovery can be entered thanks to `adb reboot recovery`. Those step can be used to go into a custom recovery like TWRP !
 |
WARNING: Please make sure you have a custom recovery like TWRP, otherwise it will format all the data |
- Push and maintain `power` and `volume down` buttons
- When LG bootscreen appears release the buttons
- Push `power`, `volume up` and `volume down` buttons
- The screen should display "Factory hard reset", release the buttons
- There are two confirmation, press power twice to confirm
- Custom recovery will launch
Download mode
This mode can be used with "LG mobile support tool" in order to restore factory software. It seems to be proprietary protocol
- Shut down the tablet, disconnect USB cable
- Push and maintain `volume up` button
- Connect to the computer
- Release the volume button
- The screen should display "Download mode" in a white square, the blacklight seems to be at minimum so it might be difficult to read in bright light
boot.img signature
While boot.img are not really signed, a magic word needs to be appended to it for the device to boot without complaining about "Secure booting error".
Someone kindly created a tool called Open Bump to easily add this magic word the bootloader is looking for. An updated Python 3 version is available from here, then it is as easy as:
- Executing `./open_bump.py boot.img`
- Flashing the resulting `boot_bumped.img` to the phone thanks to `dd` or TWRP install image feature.
