Hi all, Sorry if this is already posted somewhere - I couldn't find it. I have a 4S running iOS5.1 which I jailbroke using greenpoison and cydia. I saved blobs using tinyumbrella a while ago. I wanted to do a reset but it was greyed out in itunes so after googling, I used tinyumbrella to enter recovery mode. Since then, I cannot get out of the loop! My phone does not turn off, just goes to sleep (black screen). When I try to go into DFU mode it goes from the apple logo to the itunes screen but my mac does not recognize it. Since my computer won't recognize it, I can't use tinyumbrella to kick out of recovery or fix recovery. I also tried re-installing itunes to no avail. What do you think? Should I just take it to my carrier and cry a litte? Thanks for your help!
