Did you write the Orig. nand back and then unhook the cool runner. Or did you just switch the coolrunner to PRG to attempt the stock boot?

 

[x23are]

i switched to prog and just desoldered Vcc & cpu_PLL_BYpass from CR.

I don't know if this has any bearing on it, but my command for flashing the original nand back didn't have the "0 50" at the end.

It was simply:

c:\nandpro3\nandpro usb: -w16 nanddump.bin

I'm, in no way, an expert. Just trying to share my experience that worked in the event that it may help you.



Good Luck!!

I left my coolrunner connected/running and it boots my original Nand dump fine.

I wrote my original Dump back with

nandpro usb: -w16 nanddump.bin

Not just the first 50 blocks

Also check your solder points for for shorts. I was getting RROD on my original Nand when the STBY_CLK had come loose on the Motherboard.

i tried retail image and my orig dumped nand but without result. i removed CR and all wires but 0022 still appear.

dont have any idea everyone?

same problem here with 2 jasper consoles, fix would be very welcome.

try reading back your nand and comparing it with your original dump, they should match.

 

[x23are]

I dumped my nand 10 times before write ecc image.
check all dumped nand whit nand compare 1.4 - nand checker 1.1 - fc commond and nand dump tools 360.all is good.

And you do have a 16mb Jasper?

And you did try this first -w16 nanddump.bin 0 50 before erasing nand and reflashed original nand?
