I recently flashed my Samsung ms28 drive with iXtreme 1.61, but my 360 will only play retail 360 disks. All of the backup’s I’ve burned do not fully spin up and just return the “open” message after about 1 minute of quick small spin up attempts.
I have flashed my DVD twice actually, first using iPrep 11.6 per the video tutorial created by Cofree, and then again using Jungleflasher 1.73 using another video tutorial I found here. Jungleflasher shows me that iXtreme 1.61 is flashed to my DVD drive and reports the proper drive key, so I'm 100% confident that my drive is flashed properly.
I’m using a TSSTcorp CD/DVDW SH-S182M drive to burn the backups -- it has the latest firmware installed. This drive seems incapable of burning DL disks slower than 4x, so even when I tell ImgBurn 2.5.1.0 to write at 2.4x, I get a speed mismatch and the disk is written at 4x.
The very first backup disk I burned after flashing my drive was made using a Sony DL disk. ImgBurn reports this disk as “MBIPG101-R10-65”. This disk booted on my 360 without a problem the very first time. I didn’t play the game, but just left it running the intro for about 10 minutes. The reason I didn’t play the game was because I wanted to make sure everything was OK before closing my 360 backup. So I then powered my 360 down and put everything back together. Since then, my 360 will only play retail disks. It won't even boot that one disk that originally worked.
Since That Sony DL disk was my last, I bought some Memorex disks that ImgBurn reports as “RITEK-S04-66”. I read somewhere that people have great success with these disks. I’ve burned 4 of these disks so far, none of them boot. I have verified all of the disks using abgx 1.0.2, and some report video partition errors, however I’m not sure if that’s just because it’s not finding the abgx wave 3-6 update I installed. I have one backup disk that clears abgx perfectly, but that doesn’t work on my 360 either; Its a wave 3 disk.
So do I need a new DVD burner, new disks, both or am I doing something wrong? I’m a bit frustrated because of all the work I’ve put into hacking my 360 and now it’s just not working.

Any help or advice would be greatly appreciated.
Thanks,
