Error code 21 when updating from jailbreak 5.0.1
I havent found how to fix this so Im gonna leave it to the experts here
So I have an iPhone 4S and Ive had it jailbroken on 5.0.1 for a while now, recently I started experimenting few errors on my phone, like random lock ups and then my phone goes crazy and says I have no service "Searching..." and a few other annoyances so I decided to update to 5.1.1. Problem is, I cant.
I backed up all my settings/apps/info, including cydia, and when I click "RESTORE" it gives me this error,
"'verifying the install with apple' with an error code saying 'the iPhone could not be restored. An unknown error occurred (21)"
It then puts the iPhone into recovery and i have to use Tinyumbrella to exit recovery mode.
I have also tried DFU mode and gives me "error occurred (1600)"
Can anyone help me with this?
Many thanks in advance
