well, heres a strange one.
i had xbreboot_8955_1 on both xenons before i updated. then flashed version 3 and now, i have 2 dead xenons (not powering on, at all).
tried erasing flash and reinstalling version1, still dead.
tried flashing original dumps (one was 6XXX kernel, one was 5XXX), still nothing.
tried xell, nada.
i've also tried the bad flash recovery here: http://team-xecuter.com/forums/showthread.php?t=52213
and still it doesnt want to work. however, when i load nandpro, it detects the flash config fine (01198010) and im able to flash, however i also sometimes get various write errors (208, 210, 250, 280) with nandpro. (these never used to be here)
the powerbrick is fine, and so is the soldering (checked the brick on my online xbox, and i have flashed before with the current setup, however to eliminate the possibility of a loose wire, i redid all the soldering and checked with a multimeter to make sure)
anyone care to shed some light on the situation?
EDIT: FIXED, It was pins 41-44 that needed shorting.
