need your expert advice guys. i have placed my iphone into DFU mode. i had an error 1600 when i tried restoring the first time, but i fixed that with iReb. now, i have successfully restored from itunes my iphone 3gs 4.0.2 to 4.3.3 using Shift + restore and selecting the 4.3.3 FW. so i go on with redsnow_win_0.9.6rc16 and install cydia and the ipad baseband. redsnow says done, and i see the phone in verbose, then the pineapple logo and the horizontal bar slowly filling up. and then, phone won't come on - still in DFU mode (black screen). it won't turn on no matter what i do. it won't get out of DFU mode.
