Actual FW is T-MST10PDEUC-1036.0,BT-G

If I change the DNS to the Number from the start-post there is no internet anymore. (may normal)
If I try UPDATE anyway -> "800 Recource - ERROR"

I tried 8.8.8.8 just to check if other dns is working. Then of course your FW is not available, but the connection works normal.

So there is no FW for my device or another problem?

regards

PS: I just look out for a way to view recorded TV on PC later ... DeSTROi doesn't work with E-series as I read here ... If there is a way without modified FW please tell me.

Sorry. Samsung changed the game when they introduced the E-series (which means this is true for the F-series too) ..

Before the E-series the Destroi tool was able to extract keys from the .mdb file that was created by the TV for each recording.
Beginning with the E-series the key is no longer present in the .mdb file, and thus Destroi fails to get a valid key.
The Destroi keygrabber-module is also obsoleted by the new algorithm used by Samsung.

The key is now contained inside the .ss (Secure Storage) that was created by the TV for each recording.
This "secure storage" is strongly encrypted by secure hardware inside TV, and there is simply no way to
retrieve this "master key" used to create the .ss files containing the keys we need to decrypt recordings.

So, the "Destroi approach" is no longer possible. So sorry.

Brilliant minds in the SamyGO community have come up with an elegant solution.

Hooking into a number of functions inside the TV, it is possible to trick TV into thinking that
some recording is about to be played, and the secure crypto-engine inside the TV calculate the needed
key for playback, and return it to the playback-engine of the TV .. At THAT point the key gets copied to a .key file for
later use (by us), and TV is tricked into thinking playback was done successfully .. Net result .. you now have the bloody key :-)

OK, count the number of times I said "inside TV", or similar words in the above .. :-)

Yes, root is mandatory for E and F-series .. No off-line attack is currently possible.
The secure storage technology used is a "hard" problem to circumvent.

You may see/use an example of the rooted solution here: viewtopic.php?f=63&t=6511

Best of luck with your TV :lol:
