Get March OTA without having to re-install Magisk/TWRP

I read some stuff about doing an OTA update with Magisk (v18) on my Pixel 3 (Feb 2019), but I still have a few questions about doing it. I'd rather avoid re-installing TWRP and Magisk from recovery again, and I'd like to be able to do this all without my computer if possible (see planned process below).
1. From what I've read, I should be able to restore a stock boot image to the inactive boot partition (from within Magisk Manager) , then install the Update (both steps 1 and 2), then reinstall Magisk Manager to the inactive boot partition.. And then reboot, and I should have the update, and keep TWRP and Magisk, right? (just looking for confirmation of the process)
2. I never provided a stock image to Magisk when I installed it originally, and I don't have one right now. How do I extract the boot image from the stock image on the Android website?
3. And do I need to indicate to Magisk that I have a boot image, or will it ask me when I go in to restore non-root?
4. Are OTA updates cumulative, or do I need to update the stock boot image each update?
Thanks!

Although what you described works for some devices it won't on the pixel. To update and have twrp and root you'll need a pc. If the ota would flash when you have twrp and root, it won't, it would overwrite twrp and the patched boot image. So you're back to needing a pc to get twrp and install magisk.
For your other questions, if you extract the factory image you'll find another zip file in there. That's were the image files are and you need to extract that zip. And, ota's are cumulative so you don't need install previous ones. But specifically to the boot image, a previous months boot image may or may not be the same as the current one, etc.

I'm confused then. Isn't the method I described specifically for a phone with two boot partitions?
The instructions I am trying to reference:
Devices with A/B Partitions
Due to the fact that these devices have two separate partitions, it is possible to have the OTA installed to the inactive slot and have Magisk Manager to install Magisk onto the updated partition. The out-of-the-box OTA installation works seamlessly and Magisk can be preserved after the installation.
After restoring stock boot image, apply OTAs as you normally would (Settings → System → System Update).
Wait for the installation to be fully done (both step 1 and step 2 of the OTA), do not press the restart button!! Instead, go to (Magisk Manager → Install → Install to Inactive Slot) and install Magisk to the slot that the OTA engine just updated.
After installation is done, press the reboot button in Magisk Manager. Under-the-hood Magisk Manager forces your device to switch to the updated slot, bypassing any possible post-OTA verifications.
After the reboot, your device should be fully updated, and most importantly, Magisk is still installed to the updated system!

It is, but it doesn't work on the pixel. Google's security, probably the M chip, but I may be wrong, prevents it from working. In theory, magisk should be able to patch a boot image on your device and you shouldn't need the magisk zip but that doesn't work either. You can certainly try what you're describing but backup at least your data partition with twrp and have it off your device before you try. Get the contents of your internal sdcard to if you have stuff there you don't want to lose.
Most likely restoring the stock boot image and trying to install the ota will just not work, but you never know.

Thanks, I'll back up my files and try that.

Well, as far as I know twrp backups only work for data (with verity and all that). Always bootloop on a vendor or system restore. Back up your data a million times and go for it. Worse thing that happens is back to zero. Wait, you said no computer? Well, put it on a free cloud saving service, have your data backed up out there. Not advertizing for any service in particular, but backing up data is something everyone should be thinking about.
I am about to go for broke on this device for the 4th time. Non boot several times, flashing, flashing, building, flashing. I have the added benefit of figuring out if cell service works as the vendor.img always breaks it. Good times mate.

I might be missing something here, so please clarify if there is a way to "Get March OTA without having to re-install Magisk/TWRP", and how. Wondering about exactly that. Thank you.

What you have quoted works fine for me. I did both February and March update with this method on my P3 and no problems.
The only thing i noticed is that it takes more than 20 minutes to do step 2 of the instalation (optimizing apps)
But to be on the safe side, please backup.
Another thing: i don't have TWRP recovery, just Magisk root

There is no way to do so. Either side loading the OTA, or fastbooting the factory image, will still require you to install root and twrp. Which, really isn't a big deal at all :good:

He doesn't have twrp and if you do have twrp the ota won't work for sure. So you're welcome to try if you're only rooted, no twrp. But patching the boot image and installing it from magisk hasn't worked, but maybe it does now. Let us know.

@dracushor87, can you confirm that the process described by @madhattr999 worked correctly? I have a Pixel 3, rooted with Magisk, without TWRP. I would like to apply the monthly updates as easily as possible: without wiping data, uninstall/reinstall Magisk, etc.

I looked through Magisk Manager, and don't see a way to "restore a stock boot image to the inactive boot partition".
In the installed state, I don't see any functions for patching or installing boot images within Magisk Manager.

Yes, i confirm. Before you start, please check if there is an update available. If there is, restore image, update, reinstall magisk and then reboot. If you reboot without reinstalling magisk, you will lose root. To install on the inactive slot, just click install in magisk manager and then you will be asked what method to use. If what i said is unclear, just requote me

Used this method after the May update finally arrived for me yesterday. Backed up everything just in case, but it worked flawlessly.

Updates with root?

Hi! I've rooted a few devices in the past, but those devices were long past their software support period. The OP6 should be still supported for at least one more year so I'm not sure if rooting is worth it if it means I lose software updates. Am I going to receive updates if I root and install magisk?

Yes.. You'll receive updates. You'll have to use full rom zip to update and you'll also lose twrp and root.
Download full update zip (1gb+)
Boot to twrp
Flash rom.zip
Flash twrp
Reboot to twrp
Flash magisk
And also: please use search, this has been answered before a few times.

After ota downloads and installs, do not reboot, back out and go to magisk. There is a module called twrp a/b retention. You run it, don't reboot yet. Open magisk up again, hit install magisk, you will get an option to install to inactive slot after an ota. Do so and then you can reboot and profit. I've been doing this since way back. It's like forgotten knowledge I guess. I just did it with ob16.

Well duh..
So, with your install type you still download full rom over OTA (yes... It does that).
Twrp retention is needed because ROM install sets stock boot/recovery. Same answer to root. (p.s I have flashed this way aswell, lots of times, the other way is more idiot proof since people seems to want to click reboot now anyhow).
Also, the way I wrote isn't an old way really, it's A way rather

Monthly updates on rooted Pixel 3

Hey guys, i used to have a Pixel 2 XL and Deuces always worked for me to install monthly updates, but this time i tried the same method and ended up with a corrupted Pixel 3, had to flash stock images to fix it.
What is the best method to install monthly updates on a rooted Pixel 3? Just edit the flass-all to remove the -w? Or is there an easier way such as uninstalling Magisk or something?
Cheers

Either flash-all minus the -w or sideload the OTA with stuck recovery. No other methods to keep data. If you are installing TWRP (and not just using the fastboot boot instance leaving stock recovery), then using the flash-all (minus -w) saves you from having to flash boot.img first to get stock recovery back. Either method will require you to re-root and reinstall TWRP.

Thanks, so there is currently no way to just click "Uninstall" from within Magisk Manager and let the OTA install automatically, right? I read a comment in another thread in which the OP was trying to do that

Could it be done? Maybe, but it would take just as much work. You would have to uninstall Magisk, TWRP, a kernel and possibly other things to get the OTA to auto-run and install properly. Then, you would have to deal with timing of the OTA showing up once you have "unmodified" the phone. OTA showing up is hit and miss. I have been doing it on both a Pixel and Pixel XL (and now P3/P3XL) since the OG was released 3 years ago. I have used OTA sideloads a couple of times when I want to force a slot change. The flash-all (without -w) is the fastest, most reliable method and requires no prework except for the -w text deletion. All of the work is on the backside. Fastboot flash TWRP, install TWRP, install kernel, root. PLus, all of your magisk hide settings are retained. You are just flashing Magisk package to bring back root. You have to do all of that with a true OTA or sideload OTA as well.

Without TWRP it is possible, I have seen people do it but I have not.
Open Magisk and uninstall root, do not reboot.
Take the OTA, do not reboot.
Open Magisk and install but install to the inactive slot since that is what you will boot to after reboot.
Reboot and cross your fingers. Don't try this unless you are near a computer and ready to flash all minus the -w.
I still prefer the flash all method. Clean, easy, fast and never fails.

Have to re-root using the Magisk method. Put stock boot on phone, patch boot with Magisk, put modded boot back on computer, and flash in fastboot. AFAIK, there is no way to retain root. Every time you flash the latest monthly patch, it flashes a new stock boot. Therefore, no root.

There's a way with taking the ota through settings I found out how from a user on here which is:
Once received the ota , go to magisk first uninstall/restore images then download/install ota then DONT REBOOT, go back to magisk install magisk to inactive slot from the app then reboot and all should work with new ota update and have root still.

What is this update 4.3mb

Once again, my phone got bricked. I wanted to sideload, so I tried to get it into recovery, it wouldn't, so I tried a few times, and decided screw it. Now my phone bootloops. So, download the image and try flashing, it won't go into fastboot and fails. No matter what I do, I can't seem to save it. Can anyone help me with this? I'm trying a different computer in a sec, but, not sure if that will work either.
Edit: The different computer doesn't see it... FML

You missed the part where I did try flashing the image. I've done this a hundred times, so, I did it right.
Anyway, I got it. I didn't realize my work computer had a USB-C port, so, I grabbed one and tried flashing the image with that. Worked! Thank God... I guess sdk tools doesn't like a USB 1 to C cable, and my phone doesn't like going into recovery...

If you are rooted flash the boot.img of the factory image you are currently on to both slots:
Code:
fastboot flash boot --slot all boot.img
Then Do #4 'keep Data'

I am starting to feel more and more like a lot of the bootloop issues are being caused by OTAs swapping slots on install. Besides the --slot all patched boot, it might help to run the OTA twice to get it to install to both slots completely. Preferably though, quit using OTAs and work with -w removed flash-all installer (and even then possibly installing to both slots with an active slot swap in between and before rooting). The double install is common when installing custom ROMs, and the process for OTA sideloads is pretty similar.

Performance improvement, feels smooth and responsive. Glad i dont need to root this phone, ppl are having so many problems.

Worked exactly the same as the 10 and .C3 builds for me. Flash-all (minus -w) and patched boot in Magisk. No issues. It was not just security this month. See the functional patches in the bulletin.

[Guide] Update and Retain Root

*Note* Some people have had success with this, while some others have not. You do this at your own risk.
Prerequisites:
Magisk Manager might need to be unhidden based on reports from some users.
Magisk needs to have a backup of stock boot.img.
Preserve AVB 2.0/dm-verity must be enabled. (Have gotten mixed reports on this it might or might not be needed)
Check the following post if you don't meet the prerequisites
https://forum.xda-developers.com/showpost.php?p=81186247&postcount=73
Update Process
When phone detects update
1. Disable any desired Magisk modules, ex. Edxposed (I usually disable all modules just to be safe)
2. Reboot
3. In Magisk, select Uninstall, press Restore Images
4. Do NOT Reboot
5. Install OTA Update via Settings -> System -> System Updates
6. When prompted to reboot, Do NOT Reboot
7. In Magisk Manager press Install
8. Select Install to Inactive Slot
9. Reboot
10. Enable the Magisk modules one by one
In case of bootloop after enabling a module there are 2 ways that I know of on how to retain root and fix bootloop.
One requires ADB
While phone is stuck in bootloop, connect phone to PC and run this commands via ADB.
adb wait-for-device shell magisk --remove-modules
adb reboot
This will remove all modules and you should be able to boot.
The second way is via fastboot. More information in this thread.
https://forum.xda-developers.com/pixel-4-xl/themes/magisk-modules-disabler-booting-magisk-t3990557
Some information that might help some people.

I know some users flash patched boot.img that someone else patched, thus bypassing the creation of a backup. I think choosing or not choosing to preserve avb 2.0/dm-verity also affects if phone will take OTA. I always preserve mine and always patch my own boot.img so I haven't ran into any issues. I'll just have to wait and see what happens on my end once I get the update. This reminds me of some issues some people where getting early on when rooting. Some people had to flash the patched boot.img to both a/b slots and some people didn't. Having both slots with a patched boot will also break the restoring of stock boot.img as Magisk only restores the active slot.

If you do it this way you'll be using the patched boot image from the previous update and not the current one.

No it doesn't. When you select install to inactive slot it patches the newly installed boot.img that has been installed to the inactive slot. Only reason phone promts you to reboot after an update is to switch slots.

For whatever reason, whenever I would try to do Uninstall - Restore images (in step 3 of the OP), I would get a toast error saying "Stock backup does not exist"
I'm not sure why the expected backup files hadn't been created. I suspect it has to do with the process of manually patching the boot image whilst initially rooting, as suggested in this Git issue.
Anyway, I was ultimately able to work around this, and was eventually able to get Uninstall - Restore images to work.
I wrote about my workaround method here.

Yeah, there needs to be a backed up stock boot img for this to work. Being able to restore images the way stated in the issue would solve this as you could just restore a stock boot.img then continue doing the steps.

So does this work for every update? Just do the steps and it works? Im a complete noob when it comes to this stuff i just follow the write ups and pray!

Yes, it has worked for me all the time. These are the exact steps recommended by topjohnwu, I just made them more readibly available to users. Here is a link to his tutorial.

Why would you need to since your not rooted with a locked bootloader? Just take the OTA.

Nope. Unless you got lucky and they sold you a google version by mistake.

There is a write up for that.

Does anybody know if this also work with a custom kernel? I thought removing root and let magisk install old (boot) image should reinstall stock boot.img (if magisk first was installed through fastboot with stock kernel). Then i can take ota, patch inactive slot with magisk and then reboot. After reboot i can install custom kernel again througj ex kernel manager app. Does anybody know if this works?

Yes this method works with custom kernel. Magisk removed custom kernel when it restores stock boot.img

When does the dec patch come out, on the 5th?
I just started the process then realized it wasn't out yet so I haven't rebooted. When I go to the step of installing to the inactive slot I get a warning that you should only do this after the ota update - does anyone know if I'll be OK to go ahead with it even though I haven't done the ota yet?

I wouldn't do it until the Dec ota comes out and that may be later today or sometime this week. Which is weird since all the other Pixels got it but hey it's Google

Since it's not out yet, just do a direct install in Magisk to re-install it

Thanks for this guide !
Does anyone know how to update and maintain root for manually updating using OTA files ? Usually the update takes a long time to reach my phone, so I update using OTA files.

The other way I update is using full factory images. Once you download the zip, extract it and find and open (via Notepad++ or similar advanced text editor) the flash-all.bat or flash-all.sh (depends on your system), find this line
fastboot -w update
replace with
fastboot update
Basically remove the -w, this will prevent a factory reset (wipe) on your device. Once it is done you will need to patch new boot.img via magisk and flash the newly patched boot.img via fastboot.
Hope this helps!
ps. I recommend to always disable Magisk Modules before updating as they could cause FC
