Sorry for the trouble, hoping you can help please.
I've been using this Slim Portable Blu-ra / DVD Writer BP50NB40 SVC Code NB40 for a few years on Blu-Rays and a few DVDs. Have a ~2009 Marley & Me Blu-Ray that had too many hash check errors. Read some posts, I think the disk is clean and in good shape, also realized I was on firmware 1.00 so I thought I'd upgrade the firmware. Read the old posts and the new SDFtool, and several posts about people being told to "follow the directions" and do both the write and the recover. Felt confused but tried anyway - big mistake.
Successfully wrote bp50nb40-nb50 1.03 (slim external drives) and that shows up. Now in MakeMKV the LibreDrive Information shows Firmware Type Patched (microcode access re-enabled), version 1.03. The Drive Information also says revision 1.03.
When I try to Recover to BU40N 1.03 MK, the first weird thing that happens is I click on the bin, click open, and the SDF FLasher (v1.3.5) still shows "please select a firmware to write". So I do it again and this time it appears in the menu. When I click start, it appears to work and is done in less than 5 seconds (much shorter than the write took the first time).
But now the drive doesn't really work and still shows the 1.03 information above, both in makemkv and in the flasher tool. The front button or "eject" does make the green light flash, but results in "disc is being loaded" animation and nothing happening. I've even tried manually opening and closing with a paper clip, it doesn't change the issue. Tried unplugging / replugging, tried restarting the computer.
Also tried Recover using BP60NB10 1.00 MK and had the same issues, both the the menu selection and the "done successfully" in a few seconds but no change from the first write.
So then I tried Recover to the bp50nb40 nb40 1.00 clean bin, like this post (
viewtopic.php?p=129930#p129930), but it has the same issue of not loading the bin the first time I select it, "done successfully" in about 3 seconds, and having the same 1.03 info / label. So, sadly, it did not work for me.
Then tried Write using the nb40 1.00 clean as well, no effect.
What did I do wrong the first time trying to update the firmware? And what am I doing wrong on the Recover side? Thank you so much for any help you can advise, sorry for yet another newb apparently not following directions, and Merry Christmas (also, Festive Festivus)!
