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.
