Thanks for your response!

Here is the current drive information from MakeMKV:

Drive Information:
OS device name: E:
Manufacturer: ASUS
Product: BW-16D1HT
Revision: 3.10
Serial number: KL8K9OG0037
Firmware date: 2019-01-04 10:14
Bus encryption flags: 1F

LibreDrive Information:
Status: Possible (with patched firmware)
Drive platform: MT1959
Hardware support: Yes
Firmware support: No
Firmware type: Original (patched version available)
Firmware version: 3.10
DVD all regions: Possible (with patched firmware)
BD raw data read: Possible (with patched firmware)
BD raw metadata read: Possible (with patched firmware)
Unrestricted read speed: Possible (with patched firmware)

No disc inserted.

I accidentally flashed the 3.10 firmware and would like to downgrade to 3.02 (or LibreDrive-compatible version) via UART. I have a DSD TECH SH-U09C adapter and I'm ready to follow the correct flashing steps.

Thanks again for your help!

No need your overthinking it.
Just follow the guide right here or email me or Marty for a automated downgrade flasher

Hello,

but I need a UART flasher for that, right?

Also, I might have missed it – could you please point me to the exact guide? The forum is quite large and a bit confusing.
