Cant Restore my iPhone to 4.1. now stuck in recovery mode
I have an iPhone 3GS with firmware 3.1.2 and 05.11.07-6.4_M3S2 baseband. My cydia button disappeared so i decided to run blackrain to get it back. This just put my phone into the recovery mode and I cant kick it out. I tried tinyumbrella but it doesnt work.
So i decided to upgrade my phone to 3.1.3 or 4.1. and both result in the error 1600, 1604, and 21. I tried the DFU and recovery mode. Neither of them work. I dont know what to do now. I would like to install OS 4.1 and jailbreak it. Is there anyway to restore it officially and then jailbreak it?
Thanks for your help!
