Hi

my xbox wont boot anymore.the light is green.I tried XeLL but no result(black screen).
coolrunner is installed(there isnt any green light on coolrunner).

today I found that j2b1.7 and j2b1.8 are short. is there any way to fix them ? where are they come from ? sb maybe?
thanks

ur console is jtag?
post img of install.
thanks for reply
its rgh2.my problem solved after changing glitch chip.

now my new issue is: when loading dump in jrunnner it say wrong header.
when I insert cpu key it doesnt say anything(bad cpu key or good one)
the console boot correctly and I have XeLL.

so I guess my nand-x connection is bad. take another dump via simple nand reader app, still wrong header.
how can I fix it ?

if its just an img with xell injected thats totally expected,as it uses a trinity bootloader for xell,just build a new img with cpu key and flash it.

may it be a fake nand ? I mean they have to rgh cause bad/miss nand or somthing.
I will flash retail to see it boot or not.
