Google Widevine DRM on Android

In SDK I change device/rockchip/rksdk/BoardConfig.mk BUILD_WITH_DRMSERVICE :=true

Then build new firmware.


Then it says edit out/target/product/rk30sdk/system/build.prop  ro.product.manufacturer & ro.product.model but not sure what to change it to.

Then you have to build update.img with kernel inside boot.


Then I use Rockchip Secure Boot Tool to generate private & public key and check 'Sign check key'

Then I click 'sign firmware' and it generates a new update.img

I then flash the new update.img.

Then I use 'UpgradeDllTool_Release_v1.3' to lock device with setting at the bottom. But don't think it locked correctly.

But I still can't play Google Widevine DRM streams.

Any help would be appreciated.

Did you rebuild uboot to enable SecureBootEn and SecureBootLock

In Serial Console:

U-Boot 2014.10-RK3288-02 (Jan 21 2015 - 17:07:53)
...
SecureBootEn = 0, SecureBootLock = 0

They should both be set to 1
