Ultimate UHD Drives Flashing Guide Updated 2025

[krs24]

Hello! I'm trying to flash my LG Slim BP50NB40 NB50 but I've ran into a problem while following the guide on the "SDFTool Flasher" forum. Here are the steps I've taken so far:

1. Installed SDFTool Flasher v1.3.5
2. I wrote the firmware by the name of "HL-DT-ST-BD-RE_BP50NB40-NB50-1.03-NM00800-212005070917.bin" onto the BP50NB40. I got this file from the "The all you need firmware pack" under the "LG slim BP50NB40-NB50" folder
3. I clicked RECOVER, selected the .bin that I just wrote onto the drive, and used the firmware "DE_LG_BP60NB10_1.00_MK_HBD.bin" to recover
4. I get an error window saying "Command produced error code 0x82052603"

Any help would be appreciated. I have no experience with any of this.

Don't use that old HBD firmware I made. There's no need for it. It sounds like you are doing it right, just use the BU40N 1.00 or BP60NB10 1.00-MK firmware.

This is an extremely helpful guide. Thanks Billy. I’m new to this hobby, so to clarify and make sure im understanding correctly—it seems possible to flash an LG Drive on MacOS, but that requires terminal commands, while on the other hand, doing so on Windows is a bit more straightforward, using the SDF Flasher program? I ask only because i have both a PC and a Mac, and I am deciding which is best to flash with. Also, if i flash the LG Drive on my PC, will i still be able to use the drive with makeMKV on my Mac? Thanks again for your time and help

Yes, terminal commands on Mac but you can use the SDFtool GUI on Windows. Once the drive is flashed, it'll work on Mac or Windows.
