non of the suggestion wored for me
I bought 2 x 360 core with rrod off ebay - open to find one of the worst clamp removal fixes - they had used paper as spacers and about 10g of paste lol and they had used the bolt to board method 16 m scews rammed through the gpu heatsink why ?i have alos found the non drilling method fails within a few weeks when it works
take note of what i have done i have managed to fix this issue on one of my machines
As with other 360 I have had success with i used rjb tech v 3 drill out the 8 holes etc 4 nylons below 2 above mobo etc
one machine booted but was artifacting very badly
found heating the memory chips resolved that one - 30 secons low heat 3-4 inches off board in circular motiuon
high for 1 min 10 to 14 inch from board ( make sure you use tin foil over any plastic bits caps etc )
however on the second machine ( secondary error WAS 0102 )
I got the machine to boot to the purple screen rambling on about update failed insert hard drive did as asked but kept going back to the purple screen but still getting artifacts
I then decided to ( not sure why ) corss between the bolt to board ( cpu ) and bolt through case
it booted to the purple screen with 3 reds -
i thought lets try the update file on a usb stick ( placed in the rear usb slot and stick halo 3 in the DVD drive for good mesure)
no hard drive in the machine btw
re booted but still going to the purple screen me bing me decided to push down on the cpu heatsink - the screen went green - hmm - so i pushed on the heatsink whilst re booting the xbox - the light on the pen drive flashed and next thing i know im in the dash - however still artifacting on screen
halo 3 also boots
rebooted no more purple screen - update issue - maybe this is somthing to do with the connection tracks between the GPU AND THE CPU - well under the overheated GPU
next step remove all the screws and put back togethor with rjb rev 3 -
still artifacting and oddly I can see the dash - I have 3 red lights on the front and the secondary error has changed to 0101 -




hope this goes some way in others endevours to fix the purple screen of death
time for the heat gun on this one
spent 3 days fiddling to get this far -
