I have a Xenon console that has me slightly stumped (maybe prison is affecting me)

It started off as a TAGGED console that had been reported to have had an incorrect matching image flashed resulting in no power going to the console when you try to boot it up. However when i tested it it didn't power on (as expected) BUT i was still able to read and write to the nand. So i just wrote the original nand back to it as this had been supplied on a disc. And it booted up to its original 7371 dashboard.

So obviously from here on in it's easy sailing.... Wrong! I can get XeLLous on there no prob, got the CPU key. But everytime i try to flash either XBR or freeBOOT i just get a black screen. Bad blocks i hear you say? Each time i erase the nand and start from scratch by re-writing the original nand back i dump the nand after and there are no bad blocks....

So i can get XeLLous working, have the CPU key, NO bad blocks and i get black screen after writing XBR from CMD, or freeBOOT directly from JTAG Tool.

When i dumped the nand after flashing the original back, the dumps i took don't match with the original which i had supplied on disc, but they match with each other. I have also tried flashing 1 of these nand dumps and i get black screen again. The original nand when flashed works!

I have even tried flashing a clean nand with all the info plucked from the original nand and i still get black screen. Now maybe all this time in prison is affecting my thinking but i am stuck!
