Flashing BD-RE BU40N Firmware 1.05

Post by tobyreid00 »

Hello all & thank you in advance for the help. I have a Product: BD-RE BU40N Revision: 1.05 which came in a Verbatim 43888. I have read through all of the documentation (2026 UHD thread & SDFlasher thread) AI assisted searching also. According to my AI assisted searches, it will work to flash this drive, but I have not found a post from a person who actually flashed the BU40N 1.03MK firmware to this drive w/this 1.05 firmware... I found 1.04 firmware examples, but not 1.05. If anyone has, please let me know. Or, if you know this won't work, please let me know that too.

Here is the full drive info from makemkv:

Yes, no different. I've flashed over a thousand of these Verbatim's with the BU40N v1.05.
Cheers :D
