I don't know why you speak about the Persist partition, it's something you should NEVER tamper.Yes, after searching a bit, I figured it out. Sorry, about that. Still, there are some unanswered questions. For example does this update need the restoration of the Persist partition from the official rom to remain certified (keep L1 as well)?
Install ROM as it's an update, that's all.
About SafetyNet certification, it may not be certified (because based on a "Stable Beta" ROM by Xiaomi) but there is no feedbacks yet...
I don't have your device so I don't know if you can download the Widevine certificate via "Fingerprint payment" menu, in phone's settings and if this ROM version support Widevine L1 or not.
