Our service provider cricket has now released the 4.1 JB update. My friend and I have the same phone, and got the message to update at the same time. His went thru no issue – but mine downloads, starts installing, and then my poor little Droid falls over with an "E sig Verification fail" – and stops the install.

I've downloaded the zip and tried to do from the recovery, and same thing. Is there a way to bypass/shut off this evil thing?

and im running everything stock!!!! NO ROOTS OR FANCY SMANCHY ROMS OR RECOVERYS

Doing some searches to try and help some losts souls with this little phone, there is a download available on several other forums that will update this phone via Odin tar files to a 'stock' 4.1.2 firmware, it's a tool release directly from Samsung and it's available on their website.
