I don't know what to say, but I am getting f**** crazy! Most of the time I have had success to replace D2-3 boards with earliers revisions. But with some units it seems to work a while and it doesn't seem to help if I switch to another drive board. The disc starts to spin and is about to initialize the disc and suddenly it stops and repeat this again and again! I am so pissed over this. Name of the chip is Wiikey2 with latest firmware 1.3 Is the laser dead or can't the Wii supply correct voltage or signals? The funny thing is that the modded drive could work properly with another and older Wii unit. Please help me out before I blow up!
