Desperate help with a BTC drive

[Inv8r_ZIM]

I recently purchased a Digital Research Technology 16X dual-layer made by BTC. I flashed it to A190, and it burned SL media fine (in fact, better than an older Sony I have). My first attempt to burn DL was with a Fujifilm 2.4X RW disc. NTI DVD burner reported a successful burn, and while layer 1 seems to play fine, neither my standalone player, nor the BTC itself can properly play layer two. Either it locks up the software player on my computer, DVDshrink reports an I/O error, locks explorer up when you try to explore the Video_TS folder, or the settop player skips and jumps through layer two.
To try and resolve the problem, I had the dive's Liveupdate flash to the recommended A091 (which it claimed was more recent....?). Now, the drive is no longer visible on the system, and I can't seem to flash the thing back to A190.
Sooooooo...what I'm asking is if anyone knows how to A) Recover the drive and flash it back to the older, but actually functional firmware and B)Does anyone have any hints for this drive and DL burning. IS there anything like Qsuite for this dive?

Did you reboot after the flash? If you did, then try removing the drive and device manager and rebooting. After your OS can see the drive again, you can just download the latest(other) firmware and flash the drive again.

As to the burning issue, it could be a software or media issue. I've never used NTI, but I know other software (such as Nero) has issues with DL media. I would try different media and/or burning software.

Yeah, rebooted, and that's where I'm at now. The tray won't even open anymore. Found the device hidden in Win2Ks hardware manager, and have uninstalled it. Gonna try and reboot without and the with the drive attached, and see how it goes.

As far as burning software, any suggestions? I understand some people choose to use a different package for burning SL and DL media.

LATER--Okay, have now rebooted once without the drive physically attatched, and once with. Windows still doesn't see the thing, and the tray still won't open. Tried to flash it nonetheless, with MTKFLASH, and that's going nowhere. Anyone have an idea of where to go next?

Sorry - I don't know anything about BTC drives. You might check here for help:

Go to cdfreaks.
There are ways to fix a failed flash, with manual methods, involving tools like MTKFLASH.

Geez - didn't get much help at CDFreaks I see. The BTC forum over there doesn't appear to be very active - sorry - I did not realize that until now. Let me say that I know nothing about BTC's but I believe I would start here:

DOS level flashing is NORMALLY better in a drive recovery situation. Your stats show that A089 was the original FW. You might start back there with that firmware. If successful - then try A190. The A091 is up to you. Something obviously went wrong in that A190-to-A091 flash. No telling - maybe just a bad download file. I would re-download those firmwares by the way from the links provided above. And yes - the BTC numbering schemes for firmware is extremely weird and confusing. Good luck.
