Recent State: Stuck and Loop in Recovery Mode! -> Restoring only with 3.1.3 possible! Solution IDEA for the new iphone 3GS for Unlocking Would it be possible to prevent the baseband update with a hardware lock? Perhaphs with a simple short to ground of two Pins of the PMB8878-Chip (or the flash-chip, dont know exact hardware)? If yes would the restoring process abort or continue ignoring the basband update error? What do you think?

Whan i start blackra1n the second time it says waiting ... . after about one minute the iphone restarts and there is the recovery mode again and then again the pic of blackra1n, then again about one minute and the iphone restarts and is again in recovery mode, that could be continued in an infitiv loop, nothing changes.

(only difference, my reboot was caused because of resetting network settings). I tried the same methods as you, without succes. The first informations of my iphone in irecovery is as folowing: [FTL:MSG] Apple NAND Driver (AND) RO [NAND] Found Chip ID 0x ... 4 lines ... [FTL:MSG] FIL_Init [OK] [FTL:MSG] BUF_Init [OK] [FTL:MSG] FPart Init [OK] read new style signature 0x43313133 (line:375) [FTL:MSG] VSVFL Register [OK] [FTL:MSG] VFL Init [OK] [FTL:MSG] VFL_Open [OK] [FTL:MSG] YAFTL Register [OK] yaFTL::YAFTL_Open(l:2630): CXT is not valid . Performing full NAND R/O restore . .. [FTL:MSG] FTL_Open [OK] Boot Failure Count: 15 Panic Fail Cont: 0 Delaying boot for 0 seconds. Hit enter to break into the command prompt... HFSInitPartition: 0x4fc2ed00 Kernelcache image not valid Entering recovery mode, starting command prompt With redsn0w, i can Install CYDIA without problems (i can see installing logos etc on screen). But after finishing i am again in recovery mode. Then i have folowing result in irecovery: [FTL:MSG] Apple NAND Driver (AND) RO [NAND] Found Chip ID 0x... 4 lines ... [FTL:MSG] FIL_Init [OK] [FTL:MSG] BUF_Init [OK] [FTL:MSG] FPart Init [OK] read new style signature 0x43313133 (line:375) [FTL:MSG] VSVFL Register [OK] [FTL:MSG] VFL Init [OK] [FTL:MSG] VFL_Open [OK] [FTL:MSG] YAFTL Register [OK] [FTL:MSG] FTL_Open [OK] Boot Failure Count: 15 Panic Fail Count: 0 Delaying boot for 0 seconds. Hit enter to break into the command prompt... HSInitPartition: 0x4ff932c0 Kernelcache image not valid Entering recovery mode, starting command prompt The message is "yaFTL::YAFTL_Open(l:2630):" is gone, but if i do blackra1n after that, i have the same result as the first. Other tries in irecovery: (Recovery) iPhone$ bootx Attempting to validate kernelcache @ 0x41000000 (Recovery) iPhone$ go Kernelcache image not valid error loading kernelcache (Recovery) iPhone$ tsys Memory image not valid Perhaps we or someone can found something, if you also write your informations by irecovery. In my case there seems a problem with the kernelcache image, perhaps there is a way to restore it without restoring the complete firmware?
