Help extract L1 from Realme 5

[axnspain]

Hello
I have a Realme 5 Pro phone that claims to have Widevine L1 capability

The fact is that I have looked in its internal files and folders to extract said L1 but I have not found anything.

Could someone tell me here or privately how to extract that from the L1 from the mobile to transfer it to a computer and download it in high quality.

Thank you

1- CDM extraction method that we know, requires root.

2- Once you root your phone, your L1 CDM will be downgraded to L3.

3- Special L1 extraction tools are not available to public.

That's all I know and I suggest not to be so interested in this subject.

Basically (and I'm keeping it simple here as it is more complicated) .... Device has 2 storage locations. 1 is the software user/general that you have read/write access too. The other is the hardware secure storage that the device uses for any kind of function that requires enhanced security,

L3 is stored in the less secure location and so it pretty simple to extract using the dumper script

L1 is in the hardware secured location. To extract from here you need to find a working exploit for your specific hardware that give you read/write access to something you should not really be able to. Then you need a script that uses the exploit to read and dump exactly what you require.

There are plently of exploits out in the public.. knowledge of how to use them is limited to a few who understand them. The scripts to use them for your need is even more limited.

If you are really up for the challenge then this is the starting point... Learn about the secure environments and how they work

Can L1 be extracted from the TEE using software or are hardware modifications required too? (I haven't read your link yet)

In some cases its all software (I can't speak for every device though)... Its all a case of finding the correct exploit for your device and then getting (writing) a script to use the exploit to basically dump the required data to somewhere that it can be read

Well, what an annoyance. I just want the L1 to download some little thing from time to time, it's not to give it whiplash or anything.

I thought it was a file inside the mobile that could be extracted more easily. I don't understand why until recently a sad chrome extension could do everything without distinction and problems and now everything is so complicated.

Does anyone know of an L1 for from time to time? I do not ask for more.

Even the chrome extension could not do everything that an L1 can ... maybe a long long time ago it could, but for the time I knew it actve it was still limited on some services

The fact that the chrome extension leaked out into public use is the reason things got more complicated... Services saw what was happening and tightened up security.... Then the method to dump L3 and the various scripts leaked and again the services saw it and tightened up even more (moving more content to L1 only).

L1 protected content is monitored by services more and so L1's are quicky revoked/blacklisted once they leak out publically which is why its very unwise for someone in posession of a working L1 to share it. In fact some of the ones shared publically before were ones being used by scene members that have somehow gotten into the hands of someone they don't want to have them... and so they leak publically purely to purposly get it revoked/blacklisted.
