Dumping Your own L3 CDM with Android Studio

[ghostexaid_1516]

This is the result of my attempt, the video cannot be played. I have tried Android 9.0，Android 10.0, Android 11 and 12, but they are still useless.
In addition, I have also tried setting the DNS of the router and my computer to 8.8.8.8, but it still hasn't worked. Please help me, thanks a lot!

Make sure you are not using a vpn or the video will not play, I just tested it again and it works fine but would not work if I had a vpn turned on.

Hi everyone, I'm having trouble getting the keys to dump. I'm using frida-server-16.1.4--android-x86_64 and running it on an emulated Pixel 3a with the Android API 34 x86_64. I can go to the bitmovin DRM demo page and play the video successfully with widevine DRM but I can't get dump_keys.py to detect and grab the keys, it just stays on "Hooks completed". Does this method not work with some of the newer APIs? I've read through the replies on this thread and a couple others and I can't seem to find any obvious reason why this wouldn't work.

Edit: maybe an important thing to note, no popup appeared saying that my device's ID needed to be verified. However the video still played. Does this mean anything?

Hi everyone, I'm having trouble getting the keys to dump.

The function names that Frida tries to hook are different if using Android 10 and above. Cedric uses Android 9 (pie) You need to give Frida some help and find the function names yourself. if you use anything different

See https://forum.videohelp.com/threads/407196-Dumping-L3-from-Android-10-11-and-12.

Hello,

I followed the description step by step.
Then the dumper makes this problem:


C:\dumper-main>Python dump_keys.py
Traceback (most recent call last):
File "C:\dumper-main\dump_keys.py", line 6, in <module>

_message.Message._CheckCalledFromGeneratedFile()
TypeError: Descriptors cannot not be created directly.
If this call came from a _pb2.py file, your generated code is out of date and must be regenerated with protoc >= 3.19.0.
If you cannot immediately regenerate your protos, some other possible workarounds are:
1. Downgrade the protobuf package to 3.20.x or lower.
2. Set PROTOCOL_BUFFERS_PYTHON_IMPLEMENTATION=python (but this will use pure-Python parsing and will be much slower).

Could you help?

I'll give you a hint:

[A_n_g_e_l_a]

Here's a thing. If every you need to downgrade a python module, from, say, a series 4 version to a series 3 version, and you are unsure which is the latest module available in series three, Just try

pip install  protobuf==3.x.x

The command will fail but will list all the versions available. which in this example is protobuf==3.20.3

What version Android are you using?
What version frida is installed in python? It should be the same (or close to the) version of the one you are pushing to the emulator.

Same as in the guide. Android 9.0 x86. The frida version I pushed to the emulator is 16.1.4. and the one in python is the same.

Edit: Fixed it. Thank you cedric8528 for the amazing guide!

Try with Android 9, like in the guide. If that works, you can try a different version. I haven't had any luck with A13 so far (haven't tried very much though) but 9-10-11 work flawlessly.

I think its because my virtual device doesn't boot up, I have changed it from auto to hardware and software for the graphics but it just times out and never starts.

I am running android studio on win11 virtual machine. Might have to try directly on my laptop.

Yeah I don't know how well it will work, running a VM (cause the AVD is essentially a VM) inside another VM. I've had problems with running it inside a VM on one host, but it was fine on another host, so ymmv.

You could try running it bare metal indeed. You could also just check my signature and use one of those.

Hi, i am stuck at this step

[Attachment 74281 - Click to enlarge]

everything else has worked until now, I get error "python was not found"

[Attachment 74282 - Click to enlarge]

I have python 3.12 and I have updated environment variables
EDIT: after restarting PC, "python dump_keys.py" seems to execute now. But with the following error

[Attachment 74283 - Click to enlarge]

EDIT#3: Reading through previous posts, multiple users had the protobuf error and just need to uninstall current version and install 3.20.1
Following post#249 on page 9.

I faced the same problem here is the solution -
To downgrade the protobuf package in your Python environment, you can use pip, the package manager for Python. Follow these steps:
Write in cmd window -
pip show protobuf
pip uninstall protobuf
pip install protobuf==3.20.1
Python dump_keys.py
All thanks to ChatGPT.

Hi Chaps...
I'm Starting right from the beginning...
Win 10... 64bit
Installed android-studio-2022.2.1.20-windows.exe I am then offered the option to download extra components, such as (Packages to install: - Google APIs Intel x86 Atom System Image (system-images;android-28;google_apis;x86) I'm sure this was so that i could emulate 9.0 pie. but on the same page it states that HAXM is not installed, do i wish to install it.
Is this normal, as it is not explained in the first part of Page 1 by cedric.


[Attachment 74307 - Click to enlarge]

I'm sure once the basics are setup the rest should be quite easy to follow.

I decided to install HAXM, oddly it states that it is not installed, so i installed it again, it stated that it was re-installed successfully.... maybe time for a reboot.

my option now..

[Attachment 74308 - Click to enlarge]

The first item seemed to be pre-installed,.. the second I attempted to create. neither has been run yet, as, typical, i am on my second windows update for today.

Should have put this as the first image,.... sorry chaps...


[Attachment 74309 - Click to enlarge]

Should I be selecting SDK Manager or Virtual Device Manager,..... trying my best to follow cedrics images.

[LastResort]

Ridiculous as this may seem, but I am almost there,.... but after reading many people having the same problem, I too have the same error.

I saw jawz22 pip list and there was a file called crypto in there,.... Angela mentioned in another page to probably try pip install crypto... yep it worked. the emulator was unbelievably slow,... said that i could wait for something to run or cancel (sorry i can't remember what it was) but deffo due to the speed of my old machine. but i managed to scroll down to bitmovin's player and clicked play,... nothing really moved, but it seemed to be enough to create my first 2 keys.... wow.... thanks cedric for the guide, and Angela and the others that contributed.

I have one question,... in order to create a new set of keys do i delete my created phone and recreate a new one????

I saw jawz22 pip list and there was a file called crypto in there,.... Angela mentioned in another page to probably try pip install crypto... yep it worked. the emulator was unbelievably slow,... said that i could wait for something to run or cancel (sorry i can't remember what it was) but deffo due to the speed of my old machine. but i managed to scroll down to bitmovin's player and clicked play,... nothing really moved, but it seemed to be enough to create my first 2 keys.... wow.... thanks cedric for the guide, and Angela and the others that contributed.

I have one question,... in order to create a new set of keys do i delete my created phone and recreate a new one????

yes, create a new AVD and dump the keys in the same way

Thanks for all the support in the thread.
I was able able to get the files.

Difficulties encountered are:

No knowing that downgrading protobuf package as explained in page 9 is required:

To downgrade the protobuf package in your Python environment, you can use pip, the package manager for Python. Follow these steps:
Write in cmd window -
pip show protobuf
pip uninstall protobuf
pip install protobuf==3.20.3
Python dump_keys.py

Also injecting proper frida server x86 or x86_64 depending on the phone selected in the Android studio in my case.

Making sure frida server in running before running dumper main in a SEPARATE terminal.

Thanks everyone.

Hi Everyone

Everything works fine, but the result is a bit different.

Can you give more information?
Android version, frida version, which dumper script, ...

[GabrielPL]

Once I have obtained the two files, how do I obtain the KEY?
