Grabbed a Verbatim 43890 at scored a Pioneer BDR-UD03 within.

I'd really like to get this cross flashed in order to rip 4k UHD. Any help would be greatly appreciated.

Thanks!

Hello,

I have a Verbatim with this BDR-UD03 drive in it but can't make it read 4K discs: it starts spinning but makes bipping sounds and eventually stops and says : "No disc inserted".

From what I read, I understand that it would be possible to crossflash it to make it read 4k discs ? (or maybe not depending on firmware version ?)

Any help/information would be greatly welcomed.

Thanks,

Vaydrek
