I have iPhone 4S 5.0.1 but I messed up and did something on root and stash file while installing on previously jailbroken device (cydia was missing). Now I cannot properly boot my phone, read alot of threads on how to SSH in DFU mode but no luck. So kinda got stuck. So my question is should I update it to 5.1 and wait for the new jailbreak? I didn't save any SHSH Blobs since redsn0w won't let me (device unsupported), tinyumbrella won't work during in DFU mode. Do I have to have the SHSH Blobs saved in order to get 5.1 jailbroken? So any suggestion is welcome.
