Having some issues jtagging one of these consoles I got in a whole sale lot. It was previously attempted to be jtagged and it booted fine to orig dash, only issue was rf board did not work.
So, dumped nand x3 with nand x. Got 2 bad blocks. Noticed they were 250 so would not have any issues flashing xell.
Flashed xell, now console does not boot, does not read/write to nand. Any help anybody? Stumped on this one. Any help would be appreciated.

Bad flash to the nand so now the nand is dead and needs to be shorted out so you can erase it and write back, easier said then done though can be tricky shorting it out had it before on one don't know what caused it but it went dead the same way.

The error is not the sane as normal. If it was a bad flash you'd be getting error detecting a flash controller. You're not. Check the psu etc and make sure the board is getting power.

nandx tested on other board read/write fine, psu tested on other board working. Also it is the correct wattage ;)

So without the board connected to the NAND x are you getting could not detect a flash controller ?

No, I think you misunderstood me. I said that nand x tested on other board, so drivers/nandx has no issues. Nand x is connected to falcon board giving can not detect flash controller.

Not from your screenshot it wasn't :)

If you're not getting that as an error message it might indicate a problem elsewhere. I had a box which would only read/write when I earthed the board properly.

in earthed, I am assuming you mean grounded. How would I go about in finding that out, never had this situation before.
I got can not detect flash controller in jtag tool.

I didn't either until the other day :)

My soldering iron is earthed so I plugged it into the wall and leaving it turned off, placed it firmly onto a ground point on the board - any one of them should do.

I'm not saying this will fix it, but it's worth a shot.
