I did some tests because of my disc read errors:
I installed 4 XGD3 games. Two of them failed. The second time I installed them it went fine. All discs were burnt by Imgburn (lates version) on an iHAS624 with LT Max on brand new Verbatims at 4x with OPC. The discs verified perfectly in Imgburn and later again in ABGX.
So it is more or less luck if I can install a game at the first try. But with a few tries I can install all games. What could be the Problem?
I use a original Xecuter PCB replacement (Liteon 401 rebuild). I strictly followed the Jungleflasher guide to flash the drive. The drive is correctly locked and I did the drive outro 3 times. I didn't get the key verified message, though.
Since I could install all 4 games in the end, I don't think that messed up connecting the cables inside of the drive.
All help is greatly appreciated!
