Okay guys maybe you can help. I have a 74850C drive I am trying to flash for a friend here's a catch although I am not sure significant this one is A0A2 and not A0A1. I read from various outlets it doesn't matter. Anyways, I have the original dummy bin file before his drive died and now on this new drive it reads dvds and really old original 360 games but it goes back to dash when ran with a (ihasB) burnt and verified games. Although the newer original games it goes and sits a white Xbox logo screen. I never encountered these problems before after all these years of flashing and yes the ribbons were not attached when flashed and reattached properly when tested. I used the newest jungle-flasher and the iprep dos method as well, but to no avail. It has been updated to the newest dash and here is the following data to be used for your evaluations:

I tried flashing a few times and same result...the newer originals just run out of dash and goes to a white screen with green xbox label in the middle but does not run the game....I am stumped here!!! Like I said dvd movies play fine and most real old games do as well so thats why I am confused here.

You mean it plays the game like its some movie with that xbox logo ?? Last time I fixed that for someone was just a bad flash and bad laser and it fixed the problem

no pot tweak haven't tried that (risk reward ratio? worth trying) I just got this drive and I don't think I should need a new laser...this has been a disaster trying to figure this out.

I dont think its the laser only cuz the drive isnt that old july 2010!

The age of the console is irrelevant!

I have had liteon 1175 drives come to for a laser replacements,several at that.

I would rebuild your OFW,by loading your OFW In source then load the stock liteon bin as target then tick spoof.

Save to file the new Re make OFW.Then close JFK and re open it.

Now load your new re-make OFW as source,then auto load LT+ 3.0.

Flash as normal.

I have had to do lately to several OFW,especially the ones that have been saved on my USB stick for some time.I do not know the cause,but I had similar problems as you have described and that's how I fixed it.

If that does not Suffice,then I would then take the attention to a pot tweak/laser replacement.
