Unlock the Bootloader is a fantasy for developers and geeks who love modifying firmware on android devices, like in the OnePlus 7 Pro, the new objective of these.
In a recent development, OnePlus 7 Pro got root access with unofficial TWRP recovery, something that has fascinated many users. However, most are unaware of the Widevine L1 certification unavailability that is obtained once the unlocking is performed in the terminal.
Widevine is a digital rights management component used by Android MediaDRM and Chrome Web Browser to ensure the security of video content. He is responsible for the quality of streaming on various platforms such as NetFlix, Amazon Prime, and other networks.
The device running the Widevine L1 certification is open for the best video streaming quality available. However, the Widevine L3 is limited to 480p or the lowest video quality. Both certificates improve content protection, video playback, standardized format, legacy system, and ensure device security.
As with the OnePlus 6 and 6T, the Chinese smartphone maker's latest flagship also gets Widevine L3 certification once its bootloader is unlocked. However, in a recent thread on the forums XDA-Developers, users report the inability to watch high-quality video content from premium streaming services like Netflix, Amazon Prime, and others, so the loss of Widevine L1 certification was evidenced.
It is not clear whether re-locking the bootloader fixes the problem on OnePlus 7 Pro or not. However, it worked on the OnePlus 6 and 6T devices.
The OnePlus devices along with the Poco F1 are the most affected by the same situation. This could be solved in the near future, but it is something that will continue to affect them every time the bootloader is unlocked.
