Additional Info

Clock Work Mod

CWM for the device can be found on Shanduur's Google Drive To install it, firstly get Android Terminal Emulator (you will probably have to install it with adb install) or perform this action directly from adb shell. Those devices are rooted by default. In the terminal, copy the files from SD-Card (/mnt/extsd) to internal storage (/mnt/sdcard). Then run following:

$ su
# cd /mnt/sdcard
# sh install-recovery.sh
# sh reboot-recovery.sh

  • [2021.02.07] Initial configuration for the device based on the Sunxi Linux 5.9 kernel, including DTS mailpatch. Does not boot.
