========================================
Hi,

Since updating to the most recent firmware I can no longer stream videos on Netflix in HD quality. I know for sure when I was on firmware version 58 it was working fine at widevine L1. Would it be possible to revert back to 58 firmware? I do not mind having to factory reset my phone to do so.

Thanks for acknowledging my issue!

@reuben4k We've tested several international devices and they all work fine (Widevine L1, HDR support). Your issue might be caused by the fact that you have Tencent-branded device flashed with worldwide firmware, meaning it has been rooted by your reseller sometime in the past. Troubleshooting issues with this configuration is a mess, which is why we strongly recommend users to steer clear from it.
I'll check around some more and get back to you if a solution is found though.

The issue was not present when I was on. . 58 firmware, it only presented after updating the firmware to 78

@reuben4k It might still be caused by your configuration, even if the issue manifested itself following the latest firmware update.

For now is it possible to revert back to 58 firmware? If so how do I go about doing it? At least with .58 firmware I had no issues apart from black crush.
