need help extracting keys from Paramount+ live stream

[aletaladro]

Hi everyone,

I'm trying to get keys from a live stream on Paramount+. I've managed to capture the license request, extract the PSSH, content ID, and JWT authorization token. I also wrote a script that generates a license challenge using a local CDM, sends it to the license server, and parses the response.

The problem:

With an L3 CDM I get error "platform status restricted", so the live stream requires L1.

With public L1 dumps I get "device revoked permanently". I tried several, all dead.

I also tried extracting my own L1 from a rooted Samsung A31, but the private key isn't exposed in the file system and l1-dumper couldn't retrieve it.

I'm not asking for keys or protected content, just technical advice: is there a reliable method to obtain a working L1 CDM (maybe from another device) or an alternative approach for Paramount+ live streams?

Live from Paramount+ is L3, your configuration probably is wrong.

I tried, but I wasn't successful.
