Hey Guys!
First time doing a JTAG, However. Now reading thru again. I think my dump has errors. And if flashing back the original dump back does not work. What can i do to save my X360?

It's a Jasper 16mb with an Exploitable Dash.

Anyone's NAND i could use. I managed to have 3-4 dumps, but not sure if they are good enough.

Also, is 2ft long for the JTAG cable too long? :S

2 ft long is too long, you can not borrow someone else nand dump because your cpu key is hashed which means no other nand dump will work with your console.

compare your dumps with hex workshop, original will not boot with jtag wires in place. You might have a dead xbox on your hands.

I used about 10 inches for my lpt cable. Maybe try nand compare tool.

@ Looouky I restored my original nand dump and my xenon booted fine with jtag wires still in place (using 3 diodes) also could he not edit his consoles info on to a donor jasper 16mb nand dump if all else fails ?

It may have an exploitable dash but if it is manufactured after June 18th it will have an unexploitable CB.

Also use nand compare to compare both your nand dumps too see if there are any differences.

how many dumps did u make?

Did you check ur CB build to make sure it's exploitable?

Checked and confirmed that the CB is exploitable. I didn't get the Flash Config, but the Flash Tool could read the file. and Degraded opened the file as well, and had very little bad blocks. Any chance of recovery?

All you need for recovery is your CPU key and a donor NAND dump. Use BinCrypt2 to extract and encrypt the KV from the donor NAND. Flash XBR to your 360 and inject the donor KV. However, you haven't told us what you've done so far and what the exact problem is. You need to give more info like if you've managed to get Xell running (boot using the eject button), what happens when you try to boot XBR, what happens when your original NAND dump is flashed back, error messages, ROL errors etc.

Hey Sabbath,

This is what happened. I did 3 Dumps of the systems original Flash.

I extracted the KV and the RawConfig file from the Original Dump and injected it into the XBR Jasper 16a Flash.

I then flashed the 360. And there was nothing on screen. No error messages only 3 Lights on the red ring.

Please kindly help. Anyone knows where i can find a Donor Jasper Flash?

I had the same exact problem the way I solved it is by first erasing the nand completely and then flash it with xbr.bin


use this command to erase

have you tried flashing back your original NAND image, if it boot your JTAG wiring is not working. This happen to me. If you get a blank screen again you know its the NAND image thats not right

I got the RROD like you did and I found stray solder on my mobo. After cleaning it everything worked. I'm not exactly certain it was the solder causing the problem but I'd take a good look at your mobo before continuing.
