well i J-Tagged a Zephyr for a customer and when i J-Tagged it there were no bad blocks and it was booting to E-79 3 out of 5 boots......i Flashed XBR
System Never Had RROD i cracked the Warrenty sticker my self
so i handed it over to him and all was good for 3 months until it started to power on and off rapidly....
anyways i brought it home and it works for a few mins then starts powering on and rapidly i tryed diodes risistors and the NAND-X Quick soulder kit and all have the same effect.. not working
now a few days later i tryed the 360 again and it worked for 2 Days and was not even booting E-79 anymore.. I restarted the system50 + times in the 2 days and it never showed one Error at all.
so now i dont know WTF is going on here......
i have J-Tagged 50 + Consoles in my area so i am not new to this..............
if u have any input on the matter please reply..
