Dumper is a Frida script to dump L3 CDMs from any Android device.

|
|

## Dependencies
|
## ** IMPORTANT **
|
||||||
|
You MUST update `DYNAMIC_FUNCTION_NAME` and `CDM_VERSION` in `script.js` to the relevant values for your device.
|
||||||
|
|
||||||
|
* `CDM_VERSION` can be retrieved using a DRM Info app.
|
||||||
|
* `DYNAMIC_FUNCTION_NAME` value is unique to your device and can be found in the file `libwvhidl.so` on your device.
|
||||||
|
|
||||||
|
If you've managed to get as far as updating `DYNAMIC_FUNCTION_NAME` but can't find your function name, create an issue and provide me with your `libwvhidl.so` file and I will give you the function name you need.
|
||||||

||||||

## Temporary disabling L1 to use L3 instead

A few phone brands let us use the L1 keybox even after unlocking the bootloader (like Xiaomi). In this case, installation of a Magisk module called [liboemcrypto-disabler](https://github.com/umylive/liboemcrypto-disabler) is necessary.

||||||
|
|
||||||
## Known issues
|
|
||||||
It seems like Google made some changes in their OEMCrypto library and it broke the script. Further investigation is needed to make it work on Android 11+, feel free to open PRs.
