Or, 'My tablet's hardware "Volume Up" button is broken, now what?'
I'm trying to root an Asus TF300TG Transformer tablet (a 2012 model, unlocked) following this guide on XDA Forum:
- I have installed the USB drivers on my computer
- Rebooted tablet to fastboot
- Flashed the TWRP recovery without problems
- (Rebooted normally, verified that tablet still works as usual)
- Rebooted to fastboot again
- Got to the point where I should boot to the new recovery
That step requires me to press the Volume Up button to select the recovery option on this screen:
In my tablet, however, the button is broken (and has been for some years now). Is there a way to get into recovery without actually pushing it?
What I've tried:
- Pushing harder
- Pushing the other two HW buttons: Volume Down moves the selection, Power does nothing
- Connecting the keyboard dock: there is a Volume Up button, but it doesn't do anything in fastboot mode; none of the dock buttons do anything
- Connecting a USB keyboard via the dock: no keypresses seem to do anything in fastboot
- Rebooting to recovery using
fastboot reboot recovery: invalid command
- Booting an image using
fastboot boot twrp.blob(and various other recovery images from my computer): loaded to tablet, then failed (note the empty error message)
downloading 'boot.img'... OKAY [ 0.398s] booting... FAILED (remote: )
Is there a different way to get to recovery?
