SBW-06D5H-U (A102, MT1959) - need downgrade-enabled (DE) firmware to flash BU40N 1.00 OmniDrive

[sfchun]

Hello everyone

I recently bought an ASUS SBW-06D5H-U optical drive.
I tried to make it LibreDrive/OmniDrive friendly, and I'm stuck on the firmware rollback lock.
Tried: Flash HL-DT-ST_BD-RE_BU40N_1.00_OmniDrive.bin and SDFtool Flasher 1.3.5 rejected it with error 0x82052603 ("Write DRAM NG 05/26/03")

I understand (from the OmniDrive Wiki) the fix is to flash a downgrade-enabled (DE) firmware matching my A-series SBW-06D5H-U first (in encrypted rawflash enc mode), which lifts the lock, then flash the BU40N 1.00 OmniDrive image.

Hoping someone can point me to (or PM me) the downgrade-enabled firmware for this drive.

The drive info:

- Model: ASUS SBW-06D5H-U
- Current firmware: A102 (A-series, encrypted)
- Platform: MT1959 (HLDS / BU40N-based variant — NOT the Pioneer E-series variant)

Could someone share / PM me the correct DE firmware for the A-series SBW-06D5H-U?
I want to use the right one and not a BW-16D1HT (desktop) or Pioneer (E-series) image to avoid bricking it.

I have a complete user dump (.tar) ready to send by PM if you need it to confirm the drive.

See guide below you must follow the flow flash chart then go to your desired fw

Or email me or Marty for an automated flasher that puts you down to 1.00

Just flash it to BU40N 1.03-MK first.
