I used Absinthe to jailbreak my 5.01 iPhone 4S last week. The jailbreak is causing some major issues with my phone so I want to restore it and try again... the only problem is I can't!
When I try and restore, I either get error 1600 or error 21 and then the iPhone goes into a recover loop with the USB cable on the screen. I've done a little bit of research and read about TinyUmbrella in order to kick it out of recovery mode, however whenever I try and restore it again, the loop restarts.
I don't know anything about TinyUmbrella having never used it before, however I read a post about unchecking "Request SHSH from Cydia" and "Set Hosts to Cydia on Exit". I've unchecked these but this hasn't changed anything - maybe I'm missing something out? I've never saved any SHSH files or anything before - as said, I've only just installed TinyUmbrella for the first time in order to kick it out of the recovery loop.
The errors occur in DFU mode too.
I hope you can help!

From TU, Unchecked set hosts file to cydia and close it.
Put iPhone into recovery mode and restore to 5.0.1 again.
If you get error, try restoring again.
