Hi guise.

Ive got a Jasper 256mb here that wont boot into Xellous from start.

This is exactley what Ive done line for line after connecting USB SPI reader:

1) Nandpro usb: -r256 orig.bin
2) Nandpro usb: -r256 kv.bin 1 1
3) Nandpro usb: -r256 kv2.bin 1 1
4) Fc kv.bin kv2.bin /b => gave no differencies
5) Nandpro JasperXell.bin: -w16 kv.bin 1 1 (Xellous SMC with Aud Clamp for JasperBB)

DC power cable, and let it sit for 10sec, then reconnect and power it up.

I get black screen for 20-30 seconds, then rrod with 0022 secondary code.

During readout of original nand I got read-error at 4A, what does 4A contain? Anyone know?

I've tried to remap following 2 differeng guides, basically saying the same thing, step by step, but still, it wont boot into Xellous.

I dont think Ive ever gotten the CPU key out of this box, seems like its just been stuck at 4A badblock.

My questions are these:

A) How do I remap badblock 4A to make this work? 04A=>3FF correct? If so, when?

B) Im using Aud_Clamp for this, could this be somehow the result of the 0022? Is it better to use normal jtag wiring when Xellous has badblocks?

Appreciate any feedback. Can supply the original dump of the nand.
