I have a iPhone 3GS that I unlocked and had jailbroken at the beginning of this year. It took me forever to figure out but I had to end up using the iPad baseband when I finally did get it unlocked and jailbroken. It worked perfectly! and just the other day i downloaded an app through Cydia, which i rarely do, and it froze so i decided to just restart my phone...It was stuck on the apple logo for the longest. So i plugged it into the computer thinking I'd be able to do a restore which is when the phone went into the itunes/usb plug on the screen and has been stuck since... I tried doing a restore with custom firmware but the "This iPhone is not eligible for the requested build" keeps coming up. So i figured I would try creating a custom firmware in redsn0w and I downloaded custom firmware and the official apple firmware and when I click the official firmware in redsn0w it keeps says "Unable to recognize specified IPSW" and the IPSW was downloaded properly and not showing up as a .ZIP or anything like that.. I've googled for the past day and cant seem to find any solutions...and i do not have the shsh saved...I dont know what that is lol but i know i dont have it... I just dont really know where to start to try and fix this problem...so ANY help at all would be MUCH appreciated! Thank you!
