Ok, I have read posts for about 3 hours and still can't get the manual update to ICS to work. Error message is E:failed to verify whole-file signature and E:signature verification failed.
I downloaded the zip file, tried renaming it update and leaving it as is. Unblocked the file in windows after downloading as well. Even completely wiped and reset phone to factory settings. Followed instructions again and still getting same error. I reformatted the SD card and redownloaded the file 10 times. I have done everything that everyone has suggested and still no luck. Any more suggestions? I am about to slam this thing to the ground. The phone is not rooted, is stock.
