I removed the BS posts... the DGF.rar link is in the first post, that is the first one that was leaked and is the correct one all sites and cloners use. There is no reason to post any others, people doing so will get -Rep'd and then banned.
well, i've copied whole folders dev_flash, dev_flash2, dev_flash3 to PC from downgraded PS3 with broken BD playback (FW 3.41) and another my PS3 which never been downgraded (FW 3.41). Compared both sets of all files using CRC (examdiff Pro). There are differences only in 3 files: xRegistry.sys, DRL1, DRL2. I've replaced these files on downgraded PS3 with files from other PS3 and it didn't help.
I'm sure there is something has been written to BD firmware while update and thus messing with PS3 flash files is just useless.
BD firmware is overwritten while update according to log file and there is some region code writting is present in logs on those PS3 with broken BD playback after downgrade.
Unless somebody will dig into BD firmware to patch it (and would be good to make it region-free) we won't fix BD playback!
This needs to be seen and added to the first post...
still no news on anyone downgrading with ps3break v1.2 ? I've posted in help and support about it, I've tried with 2 different dongles with no luck, desperate to know if someone has had success with it, seems funny how ps3break team released hex for v1.0, with delays for v1.1 and V1.2 obviously there's some issues with it.
