I have tried it for hours without success... I am mentally tired and cannot find what's wrong. I am trying to upgrade from 12611 to 13604. I have a Jasper 16mb and I dumped the nand exactly like told with the tool NandFlasher from a USB drive. All worked fine till then. I did not use an original nand dump that I had before moving to 12611.
I got blocked at the cmd under MSDOS. when i input the command "fbbuild.exe -c jasper -f 13604 -d mydata updflash.bin" I obtain the following error:
"an unhandled exception 0xC0000005 has occured, exiting..."
I tried on 2 computers (windows 7 and vista), same result.
I have tried to add the KV, smconfig and SMC BIN files in the mydata folder, still same result.
I followed step by step, triple checked I input the right keys but nothing helped. Any advice would be greatly appreciated. Thanks guys
Yeah! I'am at 13604 now! Thank You InsaneNutter!

However, after this little operation, the console doesn't boot at all. black screen... even the controllers are not recognized. I wonder if I should have not left it to 12611, I fear I have lost the functionality of my JTAG... the worst that could happen.
you need to solder a USB nand flasher to the consolee though so you can flash the nand over USB.
Can you help me with my problem? I did everything according to the instructions and don't understand what could go wrong ..
I've updated my freeboot from 13599 to 13604, then I tried to install "Xbox 360 Dashboard Update 2.0.13604.0 Download with Avatars", but x360 showed an error with code: 3524 - 0000 - 3000 - 0904 - 8007 - 0570. What should I do?
I'm honestly not sure what that error even means, when you install the update when does that error appear right away or does it get so far then fail?
Also how are you installing the update, by DVD or By USB?
I presume the update unzipped ok and was not corrupted?
it does not extract the nanddump.bin how can i do thos?If you place a dump of your current nand called "nanddump.bin" in the mydata folder Fbbuild will extract all the relevant files for you now. It should also copy any block remappings over to your new nand.
PS After deleting DashLaunch 2.22 update installed normally
it does not extract the nanddump.bin how can i do thos?
