Hello and thank u for visiting,
I have a jailbroken iPad 2 GSM 64G and today i tried to upgrade its firmware from 4.2.2 to 5.1.1 with the help of tinyUnbrella and itunes, but i forgot to take a shsh before the actual update. my device crashed and restarted meanwhile update was running, but after that my device start up perfectly. I tried to save its shsh but the version that my shsh had was 5.1.1 although it was still running 4.2.2, after that i tried to restart the device from its own menu, but it went to 10xx loop. and now when i turn my device to dfu and back it shows apple logo and after that a bar appears and starts to fill but it crashes and over again, i guess its 10xx loop right? but i couldn't fix it with TU's fox recovery mode. and when i try to restore my device using itunes it gave me 1600 error and some other ones, using redsnow couldn't solve it, i read somewhere that if i remove tcpwindowsize it can help. after that itunes gives an error about the sever cannot being contacted. anyhow i want to know if i can somehow manually flash my device and change its firmware?
please help i need my device soon, i work with it like everyday, and i live in a place that no expert is nearby so i can trust him with my iPad.
