I need help with my ipad 2 from an expert plz

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.

Help, Help, Help

 

You can't upgrade to anything but IOS 6.0 at the moment. Apple is only signing that version for the iPad 2.

 

how? can u give a like to a guide?

 

To restore to iOS 6, just put your iPad into DFU mode, untick "Set Host to Cydia", shift+click Restore on iTunes and select the iOS 6 IPSW for the iPad 2(downloadable from iPadForums or other sites) and it'll restore.

 

If you get stuck like i did- heeres a mega tip
