urgent help needed. cannot restore/update ipad
so here's the situation:
i need to factory reset my jailbroken ipad and i'm getting stuck at the screen with spinning circle. when i try to use itunes to upgrade to 5.1 it fails and gives me various error codes, update via wifi also fails with error.
so i figured if i'd remove cydia app with cydelete that may solve the problem (stupid me) now, at this point i cannot: recover cydia icon, i cannot update to 5.1 and i cannot do a factory reset. I tried using tinyumbrella but as i understand with 5.1 out tinyumbrella is not able to proxy SHSH requests. So i'm pretty much stuck with the device which i can't update can't reset and can't get the cydia icon back. is there any windows program other than itunes that can help me to perform either the update or get the cydia back. i came across various forums with the same issue (deleted cydia) but they recommend to have either iFile (i don't have one) or open SSH/ WinSCP i already downloaded the cydia .deb file but have no idea how to remote to ipad with WinSCP and transfer cydia .deb file. I spent nearly 5 hours reading various forums and trying all these things but no avail. there's gotta be a way to at least update the damn thing. (i'm OK with losing jailbreak too.) any help would be greatly appreciated thank you!
strangely enough i can do the icloud backup when i choose to reset all settings. (not erase all content and settings, it still gives me the spinning circle for hours) but i still cannot update nor recover cydia icon after that either.
