Hi everyone,
I'm really frustrated. By a dumb mistake, I today destroyed my jailbroken 5.1.1 installation and thought I could still restore to 5.1.1. Sadly, i discovered that Apple won't sign any longer. I did save my 5.1.1 blobs locally as well as on Cydia before so i thought it's still possible to restore somehow. (I'm on iP4 GSM)
First tried to restore to 5.1.1 via TinyUmbrella but soon found out it doesn't work for 5.x firmwares (I'm not too familiar with that
). So I tried restoring with redsn0w - "Restore" only for A5 devices. Then found out that i have to create a custom IPSW of my original 5.1.1 (that leaves out baseband stuff i suppose), then "stitch" the custom one to my saved 5.1.1 blobs. So i did that.
Then put my iPhone into PWN DFU mode and opened iTunes. ALT + Restore, chose the edited IPSW and waited. It said "preparing for restore" several times with fast filling loading bars. The iPhones screen turned on again, Apple logo showed up. It still said "preparing..." for some more seconds, then kicked me out with a "21" error. I'm completely desperate and confused. Tried everything several times, as described above. I don't know what to do any more.
Can anyone help me? Is it true that if i get the 21 error that i have a faulty device? Please someone enlighten me, i appreciate any help. I can't live with iOS 6 with all its design faults, sluggish performance, jb bugs and the buggy maps i rely on pretty often.
/e: tried restoring with and without the TSS server running, same error however. So it can't be a "hosts"-conflict here.
