Installation guides for system.img

  • Use the following command to back up your system partition to internal storage, then copy it via USB to your computer:
dd if=/dev/block/mmcblk0 bs=8192 skip=65536 count=548352 of=/data/media/0/system.img

Command to flash rooted system image:

dd if=/data/media/0/rootedsystem.img bs=8192 seek=65536 count=548352 of=/dev/block/mmcblk0
  • Put your device in download mode and connect it to your PC.
  • Open port.bat and make sure to write down the number after com. There maybe different com numbers but choose the one that has DIAG1 on the same line as it. Note it down this is important.
  • Hold shift and right click in any empty space in the extracted folder. Choose open command windows here.
  • In that copy and paste this
  • Send_Command.exe \\.\COM[*insert your number here]
  • Now you’re in send command mode. Nothing looks different on your phone but it’s find. It should just remain in download mode.

Do not forget to factory reset your G4, or you may be getting application crashes.

After the N update (H81210n), baseband version is at: MPSS.BO.2.5.c3-00070-M899FAAAANAZM-1 , Android v5.1 – still..

After installation of H812 version N, highly recommending to back up your phone completely with Flashfire, it restarts android in minimalist fashion, and creates an in-memory equivalent of recovery, that allows you to backup / restore (haven’t tried) all of the system partitions.
