as you can see It's a problem for signing!
Not sure why I'm getting this error,
It worked perfectly when I first installed 64 bit 12.04 version of Ubuntu without any restarts!
and I already have a fullota package!!
but after a full updates and restarting I'm encounter above error!
I did re install my ubuntu but still I get the same error,
Did I accidentally delete something? Please tell me!
Do I have to do something before making fullota again? I insist please tell me
And For information purpose only I have a metadata folder in nypone (my device name folder) and I have already build an apkcert.txt file with certificates!
thnx in advance for your replay and time
