Just successfully crossflashed my "rev. 1" BDR-S08XLT to BDR-211UBK and ripping a UHD BD for the first time. Thank you jadburner for your generous help! Also shout out to blackened2687 (and all the people who helped) for the great work.
I actually did it through a Windows KVM on Linux by the means of "SCSI passthrough" (virtio-scsi + scsi-generic), so although
your mileage could vary (as it involves quite a few "components" that
might occasionally break in one sense or another, such as the respective drivers in the Linux kernel, qemu and the virtio-scsi Windows driver), at the very least it
could work. (Now I'm wondering if it would even work through wine...given that it apparently works well for ImgBurn I suppose there's at least some support for SPTI...?)
Btw because my S08 is already a half-dead drive (red laser down; tray is hard to eject), I'm thinking of sourcing another Pioneer drive from the local second-hand market, but I'm having the following doubt:
- Does the current BDRFlash support crossflashing a drive that has been updated to an "unsafe" version (i.e. from Dec 2022 or later) of firmware? (I'm presuming that Dec 2022 was when the "downgrade lock" was introduced.) As the drive I just flashed presumably had a "safe" one. (I resisted the lure to update it when I saw the post-Dec 2022 1.51 updater.)
- Should I avoid crossflashing a drive with an "unsafe" firmware for any reason(s)? (For example, only the 1.04 and 1.05 updaters for the "12th gen" models come with a kernel. If I got a 12th gen that isn't already "UHD-ready" (but "capable"), should I procure a suitable 1.02 kernel+firmware from someone? As the BDR-211UBK 1.53 firmware I got from jadburner is a "safe" one as per my knowledge.)
