92w ago - Following up on their previous 3.55 release, today the anonymous PlayStation 3 developers have shared details on remarrying PS3 Blu-ray drives on Firmware 3.15 and 3.50 without the need for downgrading the consoles.
4. Put the service mode JIG/dongle/PSGrade into port 0 (closest to the reader) and get into factory service mode.
5. Put the created USB Mass Storage device from step 3 into port 0 (closest to the reader) and run.
Drive Init Executing means it is starting the remarry process
Drive Init Failed with big pink letters 'NG' (No Good!) means the process failed. Most likely solved by fixing the communication issue with the drive.
6. After you run the initial remarry process, do not take it out of factory service mode.
7. Put a BD movie disc in and run it on the PS3. (This restores your DRL files!)
8. Then you can take it out of factory service mode.
9. Launch as normal.

If anyone is having problems with the remarry process as I did this is how I was able to remarry 2 different machines with completely new drives and boards. One is a CECHA01 and the other is a CECHL01. One on 3.50 and one on 3.55
Followed this guide which is a very good guide. Although I kept getting NG and starting over trying to find out what bad hardware I had.
Finally I figured I'd just finish the process regardless of drive-init fail.
1- I put units in FSM with my e3 card reader (started with main power switch off)
2- Built USB thumb drive as per the instructions
3- Drive Init reports NG (here I stuffed the disk in the drive and did not remove it for the rest of the process)
4- Powered off the unit (using on off button)
5- Powered on the unit (using on off button)
6- Let Blu-Ray play for a couple minutes (never saw a picture)
7- Powered off the unit (using on off button)
8- Took the unit out of FSM
9- Power on the unit (using on off button)
10- Grin ear to ear while watching Dark Of The Night.
As I read the guide NG means that the process failed. I don't understand why but I was able to marry 2 units nor do I care they work and I am very happy.
At last got my blu ray drive to play movies As i was on kmeaw 3.55 cfw i put it to factory service mode and tried every blu ray movie i had which is a lot lol till i found 1 that played after that every movie played that i had don't if this will work for you but worth a try.
Also updated to REBUG 4.21.1 REX EDITION through xmb system update and blu ray movies still play.
As far as the NG goes I've been getting it on 2 units with replaced BD boards. I finally just inserted the newest Blu-ray disk I own while disk init was still on the screen then powered off the PS3 with the power button to get out of disk init then powered back up with the disk still in the drive and the Blu-ray showed up in XMB then started to play.
It worked fine. I've spent all day trying to figure out why I was getting NG but it worked anyway.
Finally! Thanks to Glevand! I guessed all these games with remarrying BD drive are not relative to movie playback ability.
I've tried all ways of restoring DRL files, remarrying - all was in vain. The problem is that i completely don't know from which BD DRL1/2 was used before corruption. I even installed linux and started to experiment with HRL in hope it will help.
So, now i know these hashes of DRL/CRL is a key of problem. It even doesn't depend on BD drive. You can get another BD drive, remarry - it won't resolve BD movie playback unless you'll find exactly the same DRL1/2 files as they were before deletion. So, it's simply hash inside system of files from dev_flash3.
So, you can take ANY VALID DRL file (it can be any version - lower, higher - doesn't matter), calculate SHA1 checksum and write it to VTRM FLASH using Glevand guide. That's all you need!
My mess with linux on PS3 wasn't useless and i could follow the guide quickly
