I have a Chinese phone which I've been unable to install ClockworkMod on. I decided to try booting into recovery mode to manually backup/restore the system partition.
However, if I plug my phone into my PC while it's in recovery mode and issue the command
exec '/system/bin/sh' failed: No such file or directory (2)
I can only do very limited tasks, like
adb ls / to see the filesystem, but nothing else.
How can I get adb shell working in recovery mode?
