Does anyone know if there's a way to get an Android phone to reboot into recovery mode, from the Android command line?


I do NOT have adb access.

I do NOT know the magic power-on sequence to do it from the boot loader. I've tried the common things and nothing works.

I DO have root. (And can enter commands directly on the device using a terminal emulator.)

I know it's possible, somehow, because applications like ROM Manager do it. But how?

Generally, reboot binary provides a recovery switch. After switching to root, execute this command:

/system/bin/reboot recovery

This may not work if your manufacturer doesn't support it. ROM Manager type apps uses API of Android which you can't access via Terminal Emulator directly.

You shouldn't need the full path for reboot, but this is exactly right. –  Matthew Read Mar 26 '12 at 17:30
Thanks --- worked beautifully. –  David Given Mar 26 '12 at 17:32
@MatthewRead Yup, full path is really not needed. :) But, I didn't want to leave a chance in case someone messed up with PATH variable. –  S S Mar 26 '12 at 17:46

@Otech1408 You have to have a rooted device to do this. –  onik Jun 3 '14 at 12:33
