LG BU40N SDFtool Flasher v1.3.6. "Command produced error code 0xff056103"

Post by dialogueravenous »

I'm trying to flash an LG BU40N using SDFtool Flasher v1.3.6 on Windows 10 using firmware file HL-DT-ST-BD-RE_BU40N-1.03-NM00000-211810241934.bin but when I click "start" I get the error "Command produced error code 0xff056103"
Is there something I'm doing wrong here? I have makemkv latest version installed on windows 10.

Take the disc out of the drive.

I also recommend flashing directly to DE_LG_BU40N_1.00 for your drive as your firmware is not encrypted.
Cheers :D

Oh $h!t, thank you! I flashed it to HL-DT-ST-BD-RE_BU40N-1.03-NM00000-211810241934.bin, if I want to flash to DE_LG_BU40N_1.00 can I do that without going back to the original firmware? DE_LG_BU40N_1.00 wasn't in "The all you need firmware pack". Do you know where I get that from a reputable source?

It is in my all you need firmware pack in the same location/post that you downloaded SDFtool flasher from.

Ah, I see, I was using the all you need firmware pack BillyCar11 posted in this guide which seems to be a different pack: viewtopic.php?f=16&t=19634

I haven't looked but would be suprised if his firmware pack doesn't include it.
