Jtag 0022 probs

[sknobs]

Have a 256 Jasper that has old wire jtag installed. Out of the blue it went 0022. Here is what I have done so far.....

1. Try to reflash to latest dash using orig nand dump with jtag tool. No luck.

2. Remove jtag wiring and flash back to orig nand dump.
Now, no power. Wont start.

3. Use nand flasher260 to erase MU and lower 64 nand. Nand should be blank. Then I write the original nanddump back and it completes but fails verification @ 0x0.

Any body have a tip on what to do next?

Throw it in the gutter and go buy another! Sorry man no idea about jtags.

generally not a good error,remove all JTAG wiring flash nand back to stock (hope you still have your original nand dump that has been compared to 2 other good dumps),if it still throws error have it professionally reflowed,and hope for the best,strange though that you get this error on a Jasper console.

Seeing as how it went to 0022 out of the blue it may need a reball
