I have a device, problem is that touch is NOT working and when I reboot it to recovery, I am unable to navigate because volume keys are not working with that.
I found that I can use
/sbin/recovery to do the same tasks, but another problem came in. The zip I have is NOT signed, whenever I try
/sbin/recovery --update_package=/sdcard/update.zip it says Signature Verification failed.
What should I do now? Can I disable signature verification with
