my xbox with x3 mod was working fine till today, its been about a year now and it worked great

today i was playing some media file on xbmc and after watching them i turned xbox off and then came back to turn it back on again and it stopped working

when i start my xbox it start x3 chip is blue 1 sec and turns off and then x3 chip is blue 1 sec turns off and then x3 chip is blue and power light is flashing red and green

i tired to use the back up bios but it does the same thing x3 is blue and red 1 sec turns off and same thing again and again


could someone know what the problem is

Sounds exactly the same to what mine did when i first modded my xbox, seeming though youve had it modded for a while its probably been knocked about abit and things could have came loose. Yeh back to what i was saying, when my xbox did this my problem was the D zero wire wasnt on properly, just check around all your points to see if they have become loose.

Check the dO wire and the pin header (if you did the pin header install).

i checked all the points and wires and i took the pin header apart and resoildered everything again changed the bank to load bios but still no sign of luck
