Yocto recovery image

First recovery image

This is a recovery kernel+filesystem for the Quectel EG25G Modem used in various Pine64 products

This release only brings a minimal filesystem accessible via serial (/dev/ttyS2) and ADB, based on a clean Yocto 3.1 distribution.

Flashing

This bundle should be flashed via fastboot, and needs my custom bootloader implementation. Make sure you install first the bootloader and then the recovery image.

• Find the latest bootloader from here: https://github.com/Biktorgj/quectel_lk/releases
• Flash the bootloader via 'fastboot flash aboot appsboot.mbn'
• After that, run 'fastboot reboot-bootloader' and flash:
  • fastboot flash recovery recovery.img
  • fastboot flash recoveryfs recoveryfs.ubi

Once you flashed everything, you can run 'fastboot oem reboot-recovery' from fastboot to boot it

NOTE

If something goes wrong, you might end up with a soft bricked modem. Make sure you get a copy of the Recovery repo (https://github.com/Biktorgj/quectel_eg25_recovery) and you read the instructions before using this.
