After flashing my samsung ms25 to stock fw, I now have open tray issues on discs. I reflashed back to LT+, same results, and then back to stock, same.

After doing some reading, someone said before flash to disconnect the cable ribbon ribbons going to the drive bacause it could fry the laser when powering the drive on. I’m not sure if it’s all 3 cables, or just the white one going to laser? I’m using the usbpro and ck3i to flash.

So is this true? I just flashed my benq last week to 2.0 without any issue. The samsung drive is old, Feb 2006, and a modder last year mentioned the drive was going out. So looks like I’ll be buying a drive and swapping the pcb over now.

JF tutorial never meantions having to disconnect drive ribbons. I’m certain my flashes are good, they verified write ok and followed the guide. Currently it shows stock ms25 with the key from when it was modded as a ms28

by the way the laser does come on for only about 2 seconds when the tray is opened and closed. I noticed this when I ejected tray to see if any power was going to the laser. Whether or not the laser is active when reading a disc I’m not sure. I had same open tray problems with my hitachi few months ago, and just swapped the drive and pcb to fix it.

I’ve never heard of disconnecting them while flashing. I will say though on my very first liteon I had a similar issue. Turns out one of the wires on the board came out out the wiring harness. I would suggest checking all connections and see if something came loose.

i remember reading about disconnecting the laser a while ago, however i stopped doing that, and haven’t had any problems with any of the 10-20 drives i have flashed. lasers do go bad, and you can buy just a laser online for pretty cheap, instead of getting a whole drive and swapping boards. also try calibrating the laser before replacing. http://www.se7ensins.com/forums/topic/93454-how-to-pot-tweak-xbox-360-dvd-drives/
