I have the Tevion blu ray player, and it was working great with the multi-region codes for both DVDs and blu rays. However I recently installed the firmware update from the Curtis International website as I had the blu ray of American Werewolf in London that wouldn't play. Following the update it still didn't work, and I then discovered that the region code hack no longer works. They've killed it with the update. I've spoken to their customer service about whether it's possible to go back to a previous version of the software but they're no help. They did however send me a replacement blu ray player, which was unexpected, Unfortunately it's a Philips 2000 Series, which is impossible to hack for blu rays (the DVD multi-region codes works however). So my question to you all is, can you go back to a previous version of software once you have done a firmware update? Or is it even possible to physically hack the machine with some sort of mod? Thanks.
