Re: NEW OPTION: 'UHD Friendly' Firmware Downgrade / Cross-Flash Using Official (Modified) ASUS Flasher for ASUS & LG Dri

Thank you SamuriHL for the quick reply,I am pretty much a rookie on this stuff,I know I need to read my bin file before I do anything,that being said,I think I will sit tight.I cant seem to get Dos flash to work,I even went as far as to install Windows x86 on an old PC,thinking my problem was running the 64 bit system on my main computer? On the 32 bit system I get an error stating I can't run a 16 bit application on a 32 bit system or something to that effect.I'll just keep reading and plugging along till I can get Dos flash working.I just wish there was a way I could read and save my bin file using the H&L program or some other windows based program.Oh well!
Thanks again for the assistance.

If you're trying to screw around with dosflash then you didn't read what I posted carefully enough. Take your time and make sure you fully read and understand cause dosflash is *NOT* needed and is NOT used. However, the very important thing I said was to ensure that your drive has the NS50 SVC code on the label. This requires taking the drive out and looking at it. If you fail to do this and flash it anyway, you very well may brick the drive. *IF* it has SVC code of NS50, then it's safe to flash it with either of the 2 Windows flasher programs and a DE firmware. But please...PLEASE do not flash your drive with ANYTHING until you VERIFY that it's NS50. I don't want you to end up in a situation where your drive can't read anything and then have to try to use dosflash to recover it.

WHAT A LEGEND

Just got a BW-16D1HT delivered that arrived from Amazon with 3.03 firmware, and woudln't open a 4k disc, assumed I'd have to return it. This downgraded my drive 3.02. Thank you so much!

Hello again SamuriHL,
First off,thanks for your reply and concern for me screwing it up!My WH16NS40 does have theNS50 SVC code.I have done a ton of reading and am trying to be cautious.I guess I may be overthinking it,from a lot of the posts I read it seemed imperative to read and save the flash bin and save it in a few places,just in case you had any problems flashing you could revert back to your "factory"bin.After a little more reading,it seems that the DE firmware only changes 2 data bytes which converts it to the friendly firmware.So please correct me if I am wrong-flashed with the new DE.102 bin,I can freely flash other bins and not have to worry about being unable to reflash unless I flashed locked firmware.Is this Correct?
Once again thanks for your time and effort

Ok, first things first, NS50 is exactly what you want. So that's good. The DE firmware is patched so that with the patched Windows flasher (Either the LG one or Marty's ASUS one) will allow the firmware to flash to the drive. With your 1.03 firmware on there now, if you tried to downgrade to a UHD friendly 1.02, as an example, it will fail because a stock unpatched 1.02 firmware is not downgrade enabled. So hopefully that clears up that part.

Now, as for flashing, you can flash the patched 1.02 firmware for your drive or the MK version that Mike created that restores LibreDrive functionality to the 1.03 firmware. Either option can be flashed with the windows flashers. The windows flashers use the safe method for updating a drive so there's no need to read the firmware that's on the drive first. You can just flash it and be good to go.

If you have any further questions please don't hesitate to ask. Once you settle on the firmware you want to use, flashing the drive should take only a couple of minutes and you'll be done. After you have it working with LibreDrive, I'd leave it alone and never flash it again. Once a drive is LibreDrive enabled, there's zero benefit to touching it again.
