Hi there, I am trying to recover a bricked 3GS (iBoot-359.x) for a friend. It was JB+unlocked before but I do not know which tool or method was used. I successfully used pwnage tool on my old 1st gen phone and never encountered any problems. So, I created a custom FW (unfortunately I clicked "pls activate") and uploaded ios4. Upgrade was without any problems but then I had no signal. So I read up on this and realised I should not have enabled the "pls activate" function as it was already activated and unlocked. Created a new custom FW using ios4 and tried to upload but I am getting the above errors (1600 in DFU and 1604 in rec mode) before any upgrading starts and the phone will always stay in recovery mode. Now the only way to get out of there was to restore using original apple ios4 FW, which does work fine but then the phone is not activated and I assume simlocked. Everytime I try to get a custom FW on the phone I get the above errors and I need to restore with original ios4. I also tried to restore with an older FW 3.1.2 and 3.0, to check if a custom FW of this verions would work but trying to restore with the original apple FW 3.x does not work. Itunes says that this fw is not applicable to the device. On the bottom line I have an unactivated locked (probably now un-JBed) 3GS with ios4. Anyone here could help me to get this phone activated and unlocked? (dont mind if its on ios4 or fw 3.x). ps I used the newest release of pnwage tools 4.01 for the above steps. any advice is greatly appreciated.
