[QUOTE=Phylos;2629102]This can be overcome using a hardware mod.[/QUOTE]
A hardware mod is NOT required, although people who sell them want you to think differently. But this is only relevant to flashing previous FW revisions, and does not address the issue of the encrypted digital signature required to flash any FW. A modified FW file will not pass the digital signature test.
If all one wants is to play ISO files, a $200 media box will fill the bill, and at considerably less cost than a bricked $1000 Oppo 95.
