Is there a way to downgrade the firmware on a Buffalo BRUHD-PU3 from BU11 to BU10?

[planet1]

Hello,

just wanted to report back that my Buffalo BRXL-PT6U2VB is a UHD-friendly device now:

1. Crossflashing worked like a charm with this MK firmware

Just in case you might be still interested in Buffalo firmwares, they released a new FW update tool [brdrive_fwupdater_200.exe], featuring:

a. Buffalo_BU40N_FW_Updater_2.01.exe
b. Buffalo_BH16NS58_FW_Updater_2.01.exe

Can anyone confirm if this works on a device that shows up as a BU11 rather than a BN11 in the modified ASUS flasher?

the drive can not be downgraded by the lg flasher in the case only the asus one works for that

I was thinking of getting one and they said it has BF11 on it.

i would think you are able to flash it if not mike could probably make up an MK for it

My friend with bu11 can successfully downgraded to bu11 with the "DE_flash_HL-DT-ST_BD-RE_BU40N_BU10.bin" firmware. Thanks a lot!

Hi,

I found there is a new firmware at here. I extracted the latest BU12 for my BRUHD-PU3. How can I make it as MK firmware?

Hi,

Here is the BU12 for BRUHD-PU3 extracted from buffalo.jp. According to the site, it fixed Sony BD-QL media and DVD-RW write protect. How can I make it as MK firmware? Thanks.

Interesting. I've never ever seen BFxx (or a single reference to it).

Yeah, it was an Amazon.com listing. One of the answers to a question was that it has firmware BF11. Don't know if that was actually correct or a typo? Anyway, I decided not to buy it.

congrats on the upgraded drive, one question though - what updater did you use to get to bn11, I'm seeing only the 2.00 updater from Buffalo which you linked earlier, not sure if this contains what I need?
Do I even need to update or do I just cross-flash to 1.03 from Mike?

Thanks for all the info!
