    [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.

    My guess would be to visit an official service center if you're able to, or contact support if can't reach a service center. I know they fixed it via remote control for a lot of 8 series users

    Service centre people are not doing anything they are just saying that the patch that is supposed to fix this issue isn't arrived yet

    Was this at an official OnePlus center or the place where you bought the phone?

    I saw many threads regarding this issue where people go to official service centre and they are giving lame excuses like the fixing patch hasn't arrived,etc

    Yeah, this is a common issue on pretty much all their series. I'm in the beta program and mine is still L1. But i did read a lot of post from people saying they got it fixed by either visiting a service center or via remote control. So that fact they say they can't do anything about it is indeed an easy and lame excuse.

    Yes. Unfortunately, the said "official" distributor here in my country for oneplus does not include software concerns. In verbatim they said "The limited warranty only covers product defects caused by workmanship or build materials"
    Such a shame that when this happens no one is going to fix or assist you from this. No one wants to have widevine L3 when you paid for L1 so someone must hold responsibility when this happens.

    We are all only fellow users like yourself in this community, including the admins, no one from OnePlus. Like i said in a previous post, other users got is fixed by contacting support, via mail, call or the live chat, and they got it fixed with remote control. so that will be your best option here i think. I have read of users who got it fixed by factory reset or simply changing the screen calibration and rebooting, but that seems random and a long shot at best.

    No, from OnePlus themselves. Via there official website. A guy who posted the same problem in the beta thread used the live chat, and i don't know the specifics of it but he did got it fixed in the end.

    have you unlocked your bootloader? or are you on open beta 2 if you unkocked your bootloader it is normal that you will be upgraded from l1 to l3. if you are on a11 open beta 2 there is a bug that can be fixed by restarting the mobile phone (after a restart l1 should be back.

    Update: I just assisted by a Oneplus Representative and Remote access to reflash the device. They just did MSMtool with their own zip and still Widevine is at L3. Losing hope with this one.

    While for a different model, the fix this guy managed to get applies to your OnePlus model too. Check out the link below, it seems to be the only way to fix it.

    Yes, and I mentioned that, but the only way to fix it is to bring it to a OnePlus Approved Service centre for them to fix it. Seems it requires an install of some sort. Be that 7 series or 8 Series, nothing to do with hardware, it's a software fix.
