I recently noticed while using Netflix that HD playback on my device is unsupported, but available when using Chromecast.
Using the "Example Short" video, I confirmed a max bitrate on my device of 1750kbps: http://www.netflix.com/WiMovie/Example_Short_23.976/70136810
I was under the impression that the Nexus 6 has Widevine Security level 1 implemented... a quick google search revealed the following site, along with 'DRM Info', an app which provides information of the DRM implementation on your device.

Particularly, here is a screenshot demonstrating Nexus 6 level 1 support:

See attached file for support indicated on my device:
I performed a factory reset but this failed to have an effect. I subsequently unlocked BL, flashed a factory image of 6.0.1 and relocked the BL, with no success in restoring L1 support.
If anyone has feedback, I'd appreciate it.
I have the same problem on Nexus 7 (2013) LTE. HAve you found solution for that?

Has anybody relocked the bootloader on an HTC One, or locked the Developer Edition bootloader? Does doing so restore the DRM keys?
HTC posts a big warning on the bootloader unlock page and in the product description for the HTC One Developer Edition, saying that, "With an unlocked bootloader, some content on your device may also be invalidated and cannot be accessed anymore because of invalid DRM security keys. This includes content that you may have purchased through a 3rd party vendor and through HTC."
I have found that Netflix and Hulu Plus work fine on the Developer Edition, but Google Play Movies does not. I can begin playing a purchased movie, but if I pause the movie and try to resume playback later, I get, "There was a problem while playing [31] / Touch to retry."
In researching the problem I came across Google documentation for the Widevine DRM plugin, which Google Play Movies uses. XDA won't let me post an URL, but it can be found at source.google.com/devices/drm.html. It describes three levels of security that device manufacturers can choose to implement for Widevine, two of which require that the Widevine "keybox" be made inaccessible if the device's bootloader is unlocked. The keybox is presumably where keys used to decrypt protected content are kept, which would explain the problem with Google Play Movies.
So, wondering if anyone has tried Google Play Movies after re-locking to determine if the keybox becomes accessible again. The Widevine implementation guidelines would certainly allow it to be restored, but it's not clear what HTC actually does here (and they won't tell me -- I asked).
The fact that I haven't seen a lot of posts about how to preserve the HTC DRM keys makes me think they're probably not permanently deleted when the bootloader is unlocked. There are lots of posts documenting that the Sony Xperia DRM keys are permanently deleted by unlocking, and describing how to back them up and restore them to avoid DRM problems, but there are no similar posts for HTC devices. So I'm optimistic. But it would be great if someone could confirm that DRM is restored if an unlocked bootloader is relocked.
Thanks!
So google silently pushed out a update without putting it in their blog first (strange), but I thought id make a thread for people to post noticeable changes and such. So far from my searching, ive found:
Better TV output detection (probably to fix the black screen bug people have reported)
Updated netflix & eureka_shell binary
Still does not fully use V2 API, so V1 apps still work
I am guessing this was just a patch fix build. Let me know what you guys notice.
doesn't matter as device still refuses to join network.
edit: odd. ran CCast app on pc. booted up straight away. what ever works i guess.
It now supports audio when casting entire screen. Not very high quality.
I find full screen casting better than tab casting. Text are sharper and focused compared to tab casting. Watched a 720p movie on full screen... No sync issues. Casting full screen notification hides behind video player, when player uses full screen mode.

I got this update like a week before.
Sent from my SGP321 using XDA Premium HD app
Hello guys, I would like to have information about this device if it has the Google L1 Widevine certificate in the Netflix app, which allows HD playback, if it is possible for someone to provide me with screenshots about it, thank you who can tell me this information.
Hi,
I recently flashed the mi.eu rom 12.5.10 from their site and Amazon Prime Video does not play content in HD anymore.
I cannot find the widevine cerrtificate under fingerprint payment option (only FIDO and IFAA),
However, the DRM app and netflix both register L1.
Is there any solution for this?

Did this problem happen after an update?
On which rom before?
I was on stock 12.5.2 stable from xiaomi, had everything working. Hated the google dialer.
Switched to the .eu 12.5.10 rom after bootloader unlock etc. and L1 widevine is certified on any DRM check app on Play store and even netflix. Only Prime Video has this issue for some reason that I cannot understand. Assumed that if I check for cert, it will work. That is when I saw that it does not show up under the fingerprint payment part where it usually is.

I also use a Xiaomi eu rom (weekly) and the L1 appears.
If the test indicates L1, it is probably a problem with Amazon.
Wait, I'm testing with Prime.
In the app settings I set optimal, but how do I know if in HD?
The quality looks good despite the lack of brightness
I found a series in ultra HD and it's good

Hey Shash,
I too faced issues with my redmi k20 pro with widevine certificate. It got disappeared once I open any app such as prime or Netflix. But after a reboot I can able to see widevine L1 in drm app and also in setting-lockscreen-fingerprint-finger print payment- widevine option.
Fix: Seems like issue is with video tool box.
I disabled it in setting- special features - video tool box
Rebooted the phone and verified with drm app
Cleared the data for prime and netflix
Voila!
you can also try dirty flashing the latest rom.zip file via twrp recovery and follow above steps
As Many of us facing HD streaming issue,
Amazon Prime HD streaming issue on multiple Xiaomi devices even with Widevine L1 enabled is a known bug, fix expected in future.
Solution: Just Go to the Google Play Store and search for the Prime Video app, below there is an option to JOIN BETA.
Just Join the BETA and Update the App.
You will see the Problem is solved.
Enjoy !

I suggest the following to be done if you can't get L1 status which directly links to you not able to watch Full HD videos
Go to Settings-> Password and Security -> Fingerprint -> Widevine L1 -> Click on Get Certificate
You will get your HDR thing (Widevine L1) back and you will be able to watch Full HD videos from there on.

Yeah, That's a Wonderful solution but Actually, Some Users still facing using the method you suggested. So I suggested the Join Beta Tester Method.
