So i haven't been around here for a while, after looking at the recent posts many seem to be confused, blaming and do not understand on migrating to OSS builds. In the final MIUI vendor builds the OTA functionality was blocked in order to prevent users from directly updating to OSS builds as it will be needing a MIUI 11 firmware followed by a clean flash. The same has been notified in our device changelogs. Every step and preventive measures have been taken, there's only much i can do from my side in clearing things up. We have this forum and community in place to help each other out, so lets not be pointing fingers here!
Here again i would like to make it clear with a simple guide on how to migrate onto OSS build!
Note: This update will require a CLEAN FLASH (format data), so please backup everything beforehand.
Flash the latest available MIUI 11 firmware. (Region doesn't matter!!)
Now flash Arrow Vanilla/Gapps build.
FORMAT DATA. (You'll loose all your data!)
Beware that the current available recoveries haven't been updated yet to support decryption for OSS builds at this point.
To everyone, please STOP this misconception about having the need to flash magisk in order to pass safety net. Do read the OP I've clearly mentioned there's no need of a magisk or modules for safety net. Device is certified and passes safety net out of the box without need of any modifications.
By improper usage of magisk and mods you're further complicating and breaking things when they're completely unnecessary which end up causing unrelated issues which you end up calling them rom source bugs ¯\(◉‿◉)/¯
P.S : I'm not against magisk, but when you do prefer using modifications do ask yourself on your needs and if you're able to rectify the issues it might generate. Isolate yourself from magisk or any form of modifications to recheck and confirm the issue before making a bug report.
