I have a 360 with 0021.This happened in Jungle Flasher when I went to go in vendor mode. It tells you to turn off power for 1 second, so I unplugged the power from dvd rom and plugged it back in real fast. Well when I plugged it in I got instant 3 red lights 0021 error. I might have hit the wrong pin pluggin it back in .Some 1 who knows how to xclamp ,did the xclamp for me and still 0021.
The drive is flashed correct. Something shorted,or something like that.
Il ship anywhere in the us. and pay 50 bucks for it fixed. Or if anyone interested. 100 bucks to buy, comes with intercooler ,new laser, hard drive not sure how big..,ect.. pm me .
I also have a brand new,not even arrived in the mail,ms28 drive..brand new not a refurb,payed 55 bucks for it. il do 130 with new and old drive, but no hard drive. Il also throw in a usb flash drive .2g.with iprep 8.8 ,ixtreme 1.51 ,and orig dvd key
Before this I never had any problem. Never played to much and always kept in a cool area. never over heated. The xclamp fix was done (in hopes to fix 0021) with hot gun,I really dout there were any loose connections on gpu or cpu to begin with.So if anything thats good and always was good.
Id rather have some one fix it tho..
Please if ur gonna offer to fix have very good understanding of electronics. To test some parts they have to be disconected from the motherboard,such as a cap.
p.m me with offers
