Recently I updated the firmware of my Pioneer BDR-211M from 1.52 to 1.54 version and in process lost some functionality though drive still works. Was told on other forum that its not possible to roll back and was wondering if its true. Make matters worse I don’t have a back up of that 1.52 firmware and would have to search internet to find it.
@chinobino Just had an idea that may work as far as going back to previous version. Perhaps it may be possible to alter the installation app of a previous version to look like newer version. This would require altering an old rom and have no idea if it would work considering whatever checksums or security there might be in place. Other idea is to wait for a newer version installer to come out and replace its rom file binary with the older version binary code. This is all hypothetical and probably would not work anyhow. Thanks
