I just flashed my 47DJ with 2.3(first) then 2.1, neither will let me play backups. I know the backup is good, it plays perfect on my brothers 47DJ flashed with 1.3. It plays retail games just fine. I get "unreadable disc" every time with backups. Please help if you can. Appreciate it.
Probably a laser issue.
0. Try better media and burn at slow speed (Verbatim is what I suggest (if you're already using that, never mind, go to step 1
1. Try cleaning it first (best is to open the drive and use some cleaning alcohol).. if that doesn't help.. go to step 2.
2. Try pottweaking, giving the laser more power. If that doesn't help.. go to step 3.
3. Replace the laser althogether. New ones can be bought for about 25 euros online.
