Hello!
Ok lets start. I have a jasper console w CB6750 and 512MB, dumped nand with no bad sectors flashed ecc file, installed a 360 glitch, but xell boots 1 time from 30. In xell flashed freeboot image, but console doesnt boot it. Xell boots but dashboard doesnt/

I tried a 680nf capacitor on PLL pin to GND, and 0,47mf in reset, but nothing helped.
What can you advice?

Have you tried a 32cm long wire on CPU_RST?

And look at this picture, before try passing wires in the red area and if the console doesn't glitch try how is write in the picture.

cap needs to be 680pf, not nf. long wire trick is for slims. also, did u avoid the devils rectangle?

Cap is 680pf, what does it mean "devils rectangle"? :-))

It's like the bermuda triangle of the rgh wiring. No one knows what happens there but it causes problems for some

some call it the box of death (bod). its the solder joints for the anus shaped coils on the top of the mobo.

try using 360 multi builder to make the inmages.. you can still load them how ever you want but 360 multi builder will automatically get a donor nand..
