Okay people I'm trying to downgrade my iPhone 4 on a Mac from 4.3.4 to 4.3.3 (got blobs) I went the usual Shift-Restore way on iTunes and I get error 1013 (as usual) and went into Recovery Mode when I opened Tiny Umbrella there was no Exit Recovery option so I clicked Fix Recovery, left it running for like 10 minutes to no avail. Attempted RecBoot which did nothing. Then I restored to 4.3.3 again, when it hit Recovery Mode I put it on DFU and ran Redsnow, pointed it to the 4.3.3 .ipsw and Jailbroke, that actually booted my phone but then I had no Carrier or signal. A friend suggested another fresh Restore and Redsnow and point it to the 4.3.2 .ipsw, when the phone booted I had one Signal Bar but still no Carrier. I read somewhere to install Ultrasnow and that would fix it, it didn't work. Since I need my phone I updated to 4.3.4 again but I would love to downgrade. Any ideas or solutions that don't involve Pwnage Tool before I try again? I read that I needed to uncheck all boxes in the Advanced section of Tiny Umbrella and I've also read of a TU Recovery Loop fix but don't know how to execute it. Any help would be appreciated.
