Subject: DriveBrowser - Pioneer BD Drive Firmware Database + Community Project.


Hi everyone,

Fellow BD-ROM nerd here. I've been doing deep research on Pioneer BD drives and want to share something with the community — and more importantly, invite you to help build something together!

The idea:
A ...

Not sure we will be able to fix it
I would think it would but not 100% sure

I completely understand! Actually i did flash my ad07 with firmware from the updater.exe - worked just fine

You can not flash official fw from dumped/extracted fw of pioneer updaters
In bdr flash


well, that explains it! :) But you are familiar with these cut off drives, it does at least flash when i send the firmware, but can it be flashed to the same firmware as it had? i mean, XD08 is 1.04, and i ...

Well, that was... difficult.

1.03 firmware for BDR-AD07BK, BDR-AD07R, BDR-AD07W, in official flasher form : https://mega.nz/file/quYWiSAZ#Slau74DJQ ... mrMVxa_vSs

Thank you

I have the one for the BDR-XD08 1.01 in official flasher form, is that enough, or are you interested only in the firmware ?

If the flasher is enough, you can download it here ("BDR-XD08B_S_G_TB_TS_TG_FW101EU") : https://mega.nz/file/mu5ykTiY#LA59dkv4IlyZ2r6EgSH_XiSAesNb7sDeVmhpgmVAGDg


Thanks ...

I tried using BDRFlash to flash the two firmware files S9330000.104 and S9330001.104 - it reports the firmware has a bad checksum, but from what i can see they seem fine, is there an alternative site to downloading firmware files?

If you put the drives in kernel mode you can flash the lastest fw over them

But i have Not seen that on any of my pioneers

Did you do anything that would trigger this?


Yes, once tried to update the firmware on this XD08 drive, and used the officall firmware updater, i used https://pioneer.jp ...

There might have been a mishappen on the flashing front, even though i don't have any clue how it could've happen, but right now my XD08 only reads DVDs, not BluRay (and of course not uhd) with last firmware 1.04. This also happens to my XD05 (curently not connected and dont remeber the firmware ...

Does anyone have these offical firmwares? I can't seem to find any old firmware for pioneer drives these days.

BDR-XD08 1.01 — checksum 93E02B4C
BDR-AD07 1.03 — checksum FFA23F11

I'm a little bit socked that some people find this offensive, disassembly of a program in assembly should be legit enough, and also using all the tools i've been using to figure it all out should be OK! :) As long as wireshark and the official updaters are used to document the process it should be ...

seems to be armv6 thumb 2


No, it is not any variant of ARM.

I am not speaking from assumptions based on which disassembler looks somewhat reasonable for a given binary. I have written a decent amount of code for the R8J32740 and I've spent a bit of time reverse engineering both firmware and ...

Pioneer BD drives use the Renesas R8J32740 optical drive
controller (confirmed via BDR-XD08 teardown). Firmware
decompilation confirmed ARM Thumb-2 (ARMv6) instruction
set compiled with GNU C++.


Your project sounds interesting babayaga but I'm not sure about this reference to ARMv6.

As I ...

I hope that this wouldn't sound offensive but I can't help but want to ask: in terms of like "layman interest" (i.e. getting a Pioneer drive crossflashed), is there currently any advantage of using this over BDRFlash? Or, does it aim at gaining one/some (e.g. "breakthrough" regarding post Dec 2022 ...

Makes sense to me. Like I said, it's working just fine on Blu-rays, and it's never a bad thing to take some load off my UHD drives.

I read that article about old firmware, but as the drive itself was reporting "possible, not yet enabled" for LibreDrive, I thought perhaps I had missed something ...
