I have secondhand Vodafone Smart Tab 4G. It seems to me that previous owner messed something up.

The device boots normally but I cannot enter either bootloader, fastboot, or recovery. I have tried HW combinations, RebootManager software, and ADB commands. I would like to restore the device to factory defaults, but I have no idea how to do that.

I can connect by ADB:

~ $ adb devices
List of devices attached 
1b54ef6a    device

But if I try either adb reboot bootloader, or adb reboot recovery, the device hangs on "Powered by Android" logo. If I try adb reboot fastboot it just normally reboots.

Trying to restore factory defaults from settings or running system update, the device reboots and hangs on "Powered by Android" logo.

Also the device is rooted.

  • I've faced a same kind of situation on a MTK device try just to re-flash the recovery.img and boot.img file and follow the Instructions to flash recovery without fastboot from the link below <android.stackexchange.com/questions/36265/…> this will surely fix your problem and you can access your recovery after this Jan 1, 2016 at 18:03

    @Asu unfortunately no and I no longer own the device.
