* * * [Pixel 2 XL] - UPDATE Monthly Factory Image / UPGRADE To New OS * * *

WHO IS THIS GUIDE FOR:
Anyone updating factory images within the same OS version (10 to 10)
Anyone upgrading from one OS to another (9x to Android 10)
Below is a QUICK REFERENCE guide for those who have done this before, and a DETAILED STEP BY STEP guide for the first or second timer who needs each and every step outlined. Links to all required files are also provided (make sure you are selecting the latest version)
UPDATE TO THE LATEST FACTORY IMAGE . . . UPGRADE TO THE NEXT OS. . .
PREP WORK:
* Unlocked bootloader. (*performing critical_unlock only required with bootloader versions PRIOR to TMZ20a) read it here.
* Latest SDK Platform Tools found here.
* USB 2.0 & 3.0 cables available (trust me)
* Remove screen lock security before starting
* Remove all substratum overlays
*Download and extract the latest Taimen factory image (place the second extracted folder in Platform Tools folder)
CLEAN FLASH (wipe everything) or DIRTY FLASH (keep data)
Decide now whether you want a fresh OS that will restore your device to factory setup OR if you want to flash the latest factory image but keep your data.
For a clean flash: leave the FLASH-ALL file intact, change nothing.
To retain your data: EDIT the FLASH-ALL file and REMOVE the -w near the end of the script. Save the file and reopen it to ensure the -w has been removed,
When UPGRADING from one OS to another I reco a CLEAN FLASH (leave the -w intact)
Place these files on your sdcard (either before dirty flash or from PC after clean install):
* Latest TWRP.ZIP
* Your preferred customer kernel zip, I use ElementalX kernel
* Magisk uninstall instructions In the event you need to manually uninstall and reinstall MM
* Latest Magisk.zip
* Latest Magisk Manager APK
NOTE: On Android 10, when flashing TWRP Installer, kernels, magisk , etc. in TWRP, ignore the warning "FAILED TO MOUNT '/system' (invalid argument) this is a known issue with TWRP + 10 but affects nothing :good:
QUICK REFERENCE GUIDE for updating/upgrading Pixel 2 XL:
Once you verify 'fastboot devices' on command prompt
Type flash-all to install factory image (allow it to install, and boot into system)
Hold vol down and power button to boot into bootloader
Fastboot into twrp 3.3.0-0.IMG
Flash the twrp installer 3.3.0-0.ZIP,
Flash custom kernel, I use flar2's ElementalX Kernel. SELECT THE CORRECT 9X OR ANDROID 10 KERNEL
Let the system boot up to verify.
Reboot back into twrp and flash latest magisk
Reboot to system
Profit
DETAILED STEP BY STEP GUIDE for updating monthly factory images, or upgrading to the next OS (ie: 9x to 10x)

If you get stuck at the G screen, or bootloop into TWRP, try these steps:
-Perform a hard reboot (long press the power button) or
-Get back to TWRP (whether by booting into it from fastboot, or rebooting into bootloader -long press power & vol down- then boot into recovery) and reinstall the Magisk Uninstaller in TWRP a few times.
- If you are bootlooping into TWRP with Magisk installed, READ THIS!

Make sure you have all the correct and/or latest versions of SDK Tools, factory image, TWRP.img and TWRP.zip, and Magisk
Note: as a matter of superstition, I reboot back into recovery each time after installing TWRP, cust kernel, and magisk, prior to booting into system. It is NOT required, but it works
Again, HUGE thanks to @Badger50 for his invaluable input

Sometimes it takes 5 minutes or so on first boot. If it doesn't work, do a hard restart a few times. If that doesn't work, flash magisk again in twrp.

So your bootloader _critical partition isn't unlocked?? Which can't be right either since you've been able to boot fastboot the update to P. Guess I just don't know what your trying to say.

If you flashed the factory image with no issues, then you must have completed critical_unlock as well, otherwise the new bootloader shouldn't have taken (as far as I understand).
I'd start from scratch again, and make sure you follow the process exactly. Many users have used this with no issue, so maybe you missed something? The first time I flashed the factory image to my 6P (my backup) I totally skipped flashing the boot.img, and wondered why it wouldn't boot

Kudos, just what I needed to update!

Something just seems fishy to me. I've never heard of anyone not unlocking _critical, and being able to fastboot the factory image. However, it seems that you have somehow. All I can suggest is to fastboot the 9.0 again to both slots, and let it boot up each time.
Then fastboot into twrp, flash the installer zip, and let it boot up. Then go back to twrp, flash magisk uninstaller zip, then flash custom kernel, and let it boot up. Then go back to twrp, and flash magisk 1674 again.
If none of that works, I'd unlock _critical, which will wipe your phone, and then start over.

Not mandatory, but it keeps TWRP touch screen working among other things...

Just wanted to say thanks for this!
I didn't have time to update from DP5 yesterday, but I guess that was a good thing because now there's this guide, and it worked perfectly. Upgraded from DP5/flash 2.44 and who knows what Magisk version to all the latest and greatest in no time at all.
Thanks!

Sadly goes into a bootloop for me - no idea why though

This worked for me. I had magisk installed and took the pie update. No more root. D/l the factory image and extracted the boot image to the files folder...pissmeoff they changed the name of the icon... and magisk patched the image and saved it in its folder. Found the file, moved it to the laptop then flashed it.

I think you made a mistake.

I always did that method pre Pie and it always worked but now I end up in a bootloop and I did everything according to guide

I think you use my file(boot.img) for patch_boot.img from magisk manager.
I think you must check your build number devices.
You must use file boot.img from your factory image for root.
9.0.0 (PPR1.180610.009, Aug 2018) >This is version for my devices
9.0.0 (PPR1.180610.011, Aug 2018, Telstra) >?

hey mate thanks for the input, I got a normal non testra (whatever that is) taimen - tried your boot.img and before that I tried the one from the factory image, both result in a boot loop.
I went through all stages of the Android p beta and in the end, to try solve this, I also non wipe flashed the factory image all to get the same result
could you sent me a drive Link to the patched version of yours or something?

You use adb last version for flash patch_boot.img ?
I think you should flash factory image new again and factory reset your devices.
You are use stock kernel or other kernel on your devices.

I downloaded all the latest adb and fastboot. Never touched kernel or did custom recovery, always used the magisk method since i am on a pixel device. i also got the issue that my pc doesnt recognize my pixel from time to time, you think i should do a complete wipe?

I don't sure.
You are use platfrom-tool from sdk lastversion?(for flash via fastboot mode)

If you have some problems with backup, like 255 error or something similar please check this guide: https://forum.xda-developers.com/oneplus-6/how-to/255-error-twrp-backup-restore-999-t3801632
For the Bacups use always "system_image" and "vendor_image" instead of "system" and "vendor".

Recovery partition doesn't exist, so you can't flash it. The installation guide is explained in the first post

Install method explained
Hello!
Since the install steps provided on OP maybe confusing I thought on sharing here the steps I've made in order to get TWRP working....let's call it a "noob friendly guide", ok?
Here he we go:
0 - Your bootloader must be unlocked. If it's not, then follow step 1 of the instructions provided HERE.
1 - Download both twrp-3.3.1-15-laurel_sprout-mauronofrio.img and twrp-3.3.1-15-laurel_sprout-mauronofrio-installer.zip files present on OP
2 - Download latest Magisk Installer, Magisk Uninstaller and Magisk Manager from HERE.
3 - Copy all of the above to your phone internal memory (since current TWRP doesn't allow sdcard nor USB OTG yet...)
4 - Connect the phone to your PC
5 - Reboot to bootloader
Code:
adb reboot bootloader
6 - Check your current active slot
Code:
fastboot getvar current-slot
7 - Flash TWRP image into the current inactive slot (we do this just to leave the current active slot with no changes...at least for now)
If your current active is slot b, then run:
Code:
fastboot --set-active=a
Or, if your current active is slot a, then run:
Code:
fastboot --set-active=b
And afterwards, run:
Code:
fastboot flash boot twrp-3.3.1-15-laurel_sprout-mauronofrio.img
(of course that img file must be on the same path where you have adb and fastboot...)​8 - Reboot to TWRP:
Code:
fastboot reboot
NOTE: Long press Vol+ button before hitting "ENTER" and leave it pressed until you see the Android One logo (just to force boot into recovery)​
Just a heads up:
Now we are on TWRP booted on the "previously inactive slot". The "previously active slot" continues unchanged. Nothing "bad" really happened until what we decide to do next. If we want, we can just make a TWRP backup of the current slot and nothing else. Afterwards, we could always reboot to bootloader, change to the "previously active slot" again and boot system. If we do this, we continue without TWRP and root but we would now have a TWRP backup of the system present on the "inactive slot". Anyway let's presume you really want to permanently install TWRP and ROOT your device....so let's continue.
9 - While on TWRP, install twrp-3.3.1-15-laurel_sprout-mauronofrio-installer.zip
Note that, by doing this, TWRP will be permanently installed into both slots. This means that, if someday, you want to revert to stock, you'll need to reflash stock boot.img on, at least, one of your slots.​10 - After installing TWRP zip, go to reboot menu, change to the active slot (the one you had on the beginning of these steps) and reboot to TWRP
11 - After TWRP reboots, install Magisk installer zip
12 - Finally, reboot to system
13 - Enjoy
Thank you @mauronofrio and Jyotiraditya Panda for your work on bringing TWRP to Mi A3 (laurel_sprout).
I just hope you're able to fix USB OTG and SDCard bugs and, of course, make this TWRP official.
Cheers!

Uninstall method explained (aka revert to stock)
Get boot.img, system.img and vendor.img from your stock ROM build type (EU or Global) and store them on the same folder you have adb and fastboot
Uninstall all Magisk Modules you have installed (do the same for Substratum themes, if any)
Reboot to TWRP
While on TWRP, Flash Magisk Uninstaller Zip
Reboot to bootloader
Code:
fastboot getvar current-slot
(just to make sure which slot is currently active)
Code:
fastboot flash boot boot.img
(from your stock ROM build type)
Code:
fastboot set_active [B]b[/B]
(or a, if you were on slot b)
Code:
fastboot erase boot
Code:
fastboot erase system
Code:
fastboot erase vendor
Code:
fastboot flash vendor vendor.img
(from your stock ROM build type)
Code:
fastboot flash system system.img
(from your stock ROM build type)
Code:
fastboot flash boot boot.img
(from your stock ROM build type)
Code:
fastboot reboot
By doing this your phone will now boot to the previously inactive slot, where an older system build is installed, with all your userdata preserved.
Now you just have to wait for the OTA to arrive and install it in order to have the latest stock Rom build installed without TWRP and Magisk.
NOTE:
This procedure is also intended for everyone that want to install latest stock OTA without losing userdata. The Magisk OTA Installation Tutorial could fail if you tampered with system or vendor partitions, that's why I've decided to share this procedure

There's a way to relock the bootloader???

Disabling Stock Recovery flash on MIUI

Hello This a thread to show you how to prevent the stock rom from flashing the stock recovery every time you boot up. There is a script likely located in the boot.img file of the stock rom that flashes the stock recovery every time you boot up. what you have to do is overwrite that boot.img which would disable that script from running. one easy way to do this is to flash twrp and flash magisk.zip, this will overwrite the boot.img

Google really is a friend. All I had to do was install Magisk before booting to System.
Below are my exact steps, if that helps someone.
Preliminary:
Download Magisk 17.1 zip, place it on a USB flashdrive.
Install latest magiskmanager apk from Play store (or sideload it if not on the store)
1- In Fastboot:
fastboot flash recovery twrp.img
fastboot boot twrp.img (If all goes well, this boots to TWRP; if prompted for a code, hit cancel)
2- Disconnect the cable.
Reboot to recovery once more (just to make sure, this is probably redundant; hit cancel if prompted for a code)
3- Mount USB-OTG, connect your flashdrive.
Install Magisk.
During the installation, you'll see some red fail lines, but Magisk seems to work around the encryption, just be patient.
4-Reboot System. You're done! Launch MagiskManager. Device is rooted in the process, too. (Verify with a root checker app).
Power Off. Hit Power + volume Up - You should boot to TWRP.
