Anurag_Shrivastav, Sep 26, 2018 : Updated on 12/6/2019 I have seen multiple post about people loosing root access after the OTA.. I have jotted down the below the instructions on how to retain root access after OTA updates. Follow this steps... 1.Magisk Manager → Uninstall → Restore Images). Do not reboot or you will have Magisk uninstalled. 2. Now Update the system and let it install completely. Do not press the reboot button. 3. Now install TWRP A/B Retention Script from Magisk Manger. This module is available on Magisk (if you have twrp as custom recovery) Skip this if you do not have TWRP installed 4. Go to (Magisk Manager → Install → Install to Inactive Slot) and install Magisk. 5.Once Magisk installation is done, press the reboot button in Magisk Manager. Your phone may get into bootloop once, if that happens just restart the phone again. Voila now you have your OnePlus updated and You also have Magisk installed with root access
Anurag_Shrivastav, Sep 26, 2018 : Buddy once you have lost the root access you would need flash twrp again and then install magisk.
Mr. Vandelay, Sep 26, 2018 : huh, nope you don't have to flash twrp again. Download the full update to the internal storage >> Reboot to Twrp >> install the rom and right away install magisk >> wipe cache and reboot. That's it. If you don't install magisk right after installing the update then you will loose twrp.

L1531558684761, Apr 25, 2019 : After this "tutorial" my phone did get bootloop. Restarted to stock recovery and now whenever I boot up I get instantly message: "shutting down" and get back to stock recovery again please advice
G_Joe_Sauce_xJvo, Apr 26, 2019 : Ok, so we install the OTA update, and if necessary reinstall magisk with twrp (and possibly twrp again)..my main concern is in regards to unlocking the bootloader...if I've already done the unlock through Motorola on my Moto x4 and ADB will an OTA update change the bootloader status? And if so, will the same key work again?
Kytharsis, Apr 26, 2019 : Wait, you're asking about a Motorola phone on the OP forum or are you using this as an example?

J1560613467987, Jun 15, 2019 : you can install magisk it is very useful when you are compared to the SuperSU, you can stay rooted and you can get your OTA updated this www.magiskinstaller.com website will guide you through how to root your oneplus device
Z1560786532969, Jun 17, 2019 : Greetings. I got an op5t and thought I could follow those steps. Unfortunatly the system updater asks me to reboot BEFORE the OTA update. But with that i'm afraid to loose root. I'd really like to keep root. Also is it better to hide system updater from root via magisk or doesnt IT Matter? Thanks in advance
RonanDjinnTetsu, Jun 25, 2019 at 8:21 PM : Believe it or not twrp is an obsolete project, which 8s why you want to avoid it. Unfortunately devices without a/b partitions are left out in the dark with twrp less root. Twrp has caused so much petty issues, and is only a requisite to obsolete custom rom community.
