bubbleman06 , via OnePlus 7T , Feb 23, 2021 : [widevine L3 to L1] Are there any fix for broken persist partition (persist.img)? Apparently, my local official oneplus distributor here in the Philippines does not cover software related concerns. What happened is suddenly I discovered that my Widevine suddenly went to L3 as Oneplus 7t should have Widevine L1. Searched other forums and what they think the culprit is a broken persist partition as the persist.img contains all the sensor firmware files, fingerprint firmware, as well as the DRM keys for widevine drm restrictions. Need help as I need widevine L1 to watch my favorite shows in HD/HDR.
