I need your help about a 7942 phone. My phone can't update the firmware on my system. So after some tests i make a factory reset on it but now my phone is block. I see a screen with Cisco and nothing else. I see quickly a screen to make an upload but nothing more.
I have try to use Phone doctor application to know what append and i see this :
ERR 16:31:08.366700 IMG_AUTH: verifySignedFile(): file hash doesn't match hash in sig
ERR 16:31:08.367524 IMG_AUTH: verify: *** verify with current RELEASE 7942 (built-in) key failed ***
