I have a liteon DG-16D2S 74850C. I am trying to read the keys off it before I flash it. I have a Ck3 with a probe. Its hooked up through my VT6421 Raid controller which i use to flash my other xboxes. I havent done a liteon for some time now. last time i did one you had to touch the R707 with the probe. however the xbox I have is a phat from 2007 never been opened. I follow the instruction in JF to a tee but it keeps saying Phatkey failed and my probe will not light green when i touch the MPX01. Do i need to scrape on that point?
