I managed to purchase this oddity of a disc drive with option to add a SATA hard drive from a whole sale store.. its sold as a 4 in 1 external bluray on amazon... upon bringing it home it looks like works great with regular blurays... but when i placed UHD it just spins.. im new to this process and use Windows. I understand the sdtool flasher app but all i see are firmware for lg/asus... yet not sure where the actual firmware can be found for pioneer specific drives? Will this work with uhd? and how does one get pioneer specific firmware to work with sdftool flasher? thanks!
