Job done - Xenon, Falcon and Jasper512MB all just done using this. No problems at all.
Except on my Jasper, I had a profile on the MMU which became erased when writtng back. Doh!
What I did was:
1) Used 'Flash360' on Xbox to obtain a backup image from my Freeboot (9199 Dash) Jtag xbox.
2) Used 'Freeboot Toolbox' and added my CPU key.
3) Created 'Freeboot.bin' after selecting my backup image from step 1 and appropriate Xbox Type (untick the auto detection)
4) Renamed the 'Freeboot.bin' file to 'updflash.bin' (Could have created it as that name in step 3)
5) Used 'Flash360' on Xbox to Write updateflash.bin to NAND
6) After successful flash, powerdown and unplug for 30secs.
7) Power up and job done!
I also downloaded the latest 'SystemUpdate12611' from Microsoft to update with Avatars.
As the MMU became erased, I had to go back through the system memory settings and reformat.
My Xenon does have bad blocks, but 'Flash360' takes care of all that.
