Hi guys! I was trying to upgrade my iphone 4s 5.0.1 to 5.1.1 with Redsn0w 0.9.15b3, using the "restore" option and selecting local blobs for 5.1.1 (had all the SHSH saved at Cydia & local storage with TinyUmbrella). The first time i tried to upgrade got some error...i don't remember wich one...maybe because Tinyumbrella had the "Request SHSH from Cydia". After that, the phone was in DFU Mode with black screen..but i keep trying! Next step was try to upgrade via iTunes selecting 5.1.1 ipsw and with TSS server up, and after a lot of tries the process ends with a validation error (looks like). The TSS log at TinyUmbrella seems all was Ok, received a Blob request for a 5.1.1 SHSH that i have stored, and then wrote the response....and finally..iTunes ends the process with an unknow error 1600 or 1602.. (later i learned it doesn't matter, 4s doesn't recognize TSS or Cydia SHSH's) Yesterday i tried to use the recovery fix in Redsn0w but seems doesn't work with 4s (in Mac the option is disabled, in Win, the app shows the alert "...the mode ..is not compatible with 4s..." I think i'm stucked in recovery/DFU mode, and don't know what to do (of course, i don't wish to upgrade to ios6 Any idea? Thanks in advance!
