GaryOpa, admin of PSX-Scene, has discovered a somewhat major issue, regarding PS3 downgrading. He is reporting, that the ability to play blu-ray movies was lost, after downgrading his console. However, he was able to restore the feature, by replacing his entire dev_flash2 and dev_flash3, with files he had saved previously, while on 3.41 firmware. However, this does not help people already on 3.50 firmware, hoping to downgrade, or people who have already downgraded. Stay tuned, as we can only hope a fix will be found for the masses soon. In the meantime, do not downgrade if you wish to retain blu-ray movie playback.

I was able to restore one machine I had, by copying over all the files I had in the /dev_flash2 and /dev_flash3 back to the HDD, that I had saved before when it was on v3.41

But that does not help those that were on v3.50 factory fresh or with no previous full /dev_flash2 & 3 backup.

I not sure what file was that fixed the problem.

We need more machines, more tests.


I have previously tried everything, upgrading, downgrading, using normal pup files, modded pup files, older ones, new ones, but NOPE, the only way I was able to start watching movies again was overwriting those files from my very lucky backup I had of my previous Jailbroken v3.41 /dev_flash2 and /dev_flash3 file contents.

Here's what Math said about the modified 3.41

"On Wednesday 8th December 2010, @Mathieulh said:

The people having bluray movies playback issues after downgrading, this happens because you updated to a modified PUP (psjb one) which has its /dev_flash3/ tarball swapped (probably to a debug one, debug consoles do not sport bd movies playback) with other CRL/DRL revocation files."

It doesn't happen to everyone. Everyone uses the same modified 3.41 pup file to downgrade. Some say it could be how the hex file is compiled that give some people an issue with blu-ray movie playback. If you have that issue follow the instructions I posted on the first page, it will fix it.

bump small price to pay, but you should know possible problems

a way you can bypass this issue is by downgrading to 3.41 then downgrading again to any lower firmware but use a retail pup file for any lower firmware and after downgrading that just update with the 3.41 pup file on a usb using the xmb option of updating via usb and itl install all the normal contents 3.41 had because its not a modded 3.41 your installing

mine works fine. You just have to unplug the jailbreak device and turn off the ps3. restart it like normal and it will read the disc.

I found this:

That's exactly what I already said on the first page /facepalm
