Software update failure - signature verification failed ?
I have been trying to update my S3 for a number of weeks now. It currently is running v4.0.4 kernel version 3.0.15-928452-user
I get the S/W Update notice or it comes up if I go into About device | Software Update.
I do the 284MG download and then do install, it restarts and then the CWM Recovery (5.5.0.4) gives an error for invalid command parameter, failed to verify whole file signature.
I have to restart. Does anyone know how I can get around this failure and do a successful install?
Thanks, Tom.Last edited by boardtc; 11-08-2012 at 07:45 PM.
