[App] H offline decrypting of recordings

[TheGopher]

Yes, PVRDecoder works also for me. However, online decryption takes a long time. A higher buffer will speed up that progress, but freeze the TV or abort the decryption. For me just a work around. At the moment i work on a solution for offline decryption.

I've just started today with rooting the TV and I've sucessfully rooted my UE48HU7500. This is a Samsung UHD TV with a T-NT14 firmware.

I've installed the latest SamyGoso, and installed the libPVRMakeFixedKey.so in the correct directory and after that i've ran the command as instructed

Code: Select all

This all seems successfully. After that I'm making a new recording and copy the recordings from /dtv/usb/sdb1/CONTENTS to my local pc for a offline decrypting. Since the H series isn't possible to create a keyfile in the contents folder on USB, I manually copy one of the key files to the directory and rename it to recordings name.

Problem is which ever key i'm using, even though PVRDecoder says it it sucessfully decoded i'm not able to render the file (so I assume it didn't decrypt successfully).

Now i'm in doubt where the problem is. Is my TV not using the static keyfile, or am I just decrypting it wrong?

**EDIT**
I think I found the issue why it's not working.
I checked the libPVRMakeFixedKey.log and it contained:

Code: Select all

lib_init
Error dlsym('_ZN9PVRSystem14PVRTZInterface13MakeRandomKeyEjPh') [/mtd_exe/exeTV: undefined symbol: _ZN9PVRSystem14PVRTZInterface13MakeRandomKeyEjPh]
init done...

Downgrade

[UE32FooBar]

Downgrade

I got the same undefined symbol in the log. What part should be downgraded?

I already downgraded samyGOso from 1.2.5 to 1.2.4. That did not work. Where can I find an earlier version of libPVRMakeFixedKey.zip.

I think what sectroyer is talking about is your TV firmware. Not your SamyGOso installation.

Yes

Downgrade to which Version? Mine was on 1030

Compare with other versions for you TV. I think you should stick away from more recent firmwares. Ask others (for whom it works) which version they use etc.

[JeppeTh]

I guess this only works if there exists a key named as your firmware?
I have a bluray and it's called B-FB4HRDEUC, which I guess means that this won't work for me? Or which key-file should I use?

I Downgrade firmware in 2880.2 to 2130.0 (T-MST14DEUC)

What can i do to get the .key to decrypting of recordings
