please help me.... I just upgraded my 3GS iphone to new firmware 4.3.3, and suddenly the phone went died, and could not come up again.
following is the detail story:
1st, I upgraded my iphone with redsn0w to 4.3.3, and upgraded the ipad baseband.
after upgrade I had problem with "no signal" and than I installed ultrasn0w, but got error, the installation was not success. I realized after I read some article in forum that 3gs could be fix with ultrasn0w.
Suddenly after sometime the iphone went off, I could not tether with any software. I tried redsnow 0.0.6.rc.16, but stuck in the waiting for update process, and seems that redsn0w could not communicate with my iphone. previously was worked as I used redsn0w for tethered.

above is redsn0w stuck in the middle of process:
I already uses IREB, redsn0w and any other software but It does not help.
I can put my iphone to DFU mode, and Itune can detect my iphone in the restore mode. but I could not do anything.
I could not restore to normal IOS due to my baseband is already changed.
Could anyone help, and give me the solution? I just want my iphone alive and could boot again.
thanks, appreciate your comments
