Hi everyone, first time poster to xboxhacker
I have a wee problem which I hope someone can help me with...I hope I've posted it in the correct place.
My problem is this:
I have a brand new jasper 512mb xbox which I purchased so that i could JTAG it using the NAND X USB method. I used the QSB to attach it to the mobo. Using nandpro, I read my NAND 3 times and I got these errors:

I spoke to a friend regarding these errors and he said that as long as all three dumps were the same and they matched using a compare tool I'd be fine (I think this was bad advice....)
I carried on to the next step which was connecting the jtag wires, I had issues with the DB1f1 connections I think (although using a multitester tool i had a connection) as I could not get xell to load on to the nand, so I tried the alt jtag wire solution and connected the wire to the dvd cable AUD_CLAMP and the FT2R2. I managed to get xell to work and using this method I obtained my cpu key and I thought I was on the home stretch as 360 flash tool sowed me my dvd key, cpu key and the correct xbox serial etc....Alas I was then faced with problems getting freeboot to work, I just could not get the jasper_hack_bigblock_xellous xbr to work ( i tried two or three other xellous files also) I used jtag tools also using the alt wiring option, but still no joy. At this point I had spent 2 full days, dumping my original nand back on and trying the whole process again and again and was still unable to get it working.
Finally I gave up and thought that I'd put the original nand back on (which up to this point worked and would boot up to the dashboard) and send it to my friend (who told me to ignore the errors) and let him do it, but try as I might the original nand would not work. Everytime I powered up the xbox it would have the green light in the center for 5 secs then the fan tone changed and I got 3 red lights (top left, bottom left and bottom right). I removed the jtag wires and tried flashing again but still the same outcome.
I checked my nand using nandhealer and it told me that I had EEC error blocks 0x1d0 and 0x1d1 I tried fixing it (below)

Step 1 of 2: Reading nand1_0E80.bin.............Read error(1), retrying....
Step 2 of 2: Reading nand1_0E88.bin.............Read error(1), retrying....
Can any of you guys help me or should I go shopping for a new xbox?
JANVKEM and CORY1492 seem to know their stuff, any suggestions??
Thanks for your time guys...
