Here's how I update monthly. This worked today with the latest October update. No need to disable/enable anything before/after the update. Magisk canary


download factory image
extract to platform-tools
remove -w from flash-all.bat

copy boot.img file from factory image to phone
patch boot.img file in magisk
rename patched file to boot.img
move patched boot.img from phone download folder into image zip file in platform-tools

adb reboot bootloader
flash-all.bat

download kirisakura
flash with exkm

Thanks for this. Just got my P6P last week. Haven't had a rooted device since my Nexus 6p and man have things changed. Been doing a lot of reading lately trying to catch up on everything. I'm kinda lost without Twrp and I'm starting to mess around with Pixel Flasher. I'm already unlocked and rooted, next step is to update to the October release so your post will come in handy . I'm gonna try that kernel you listed also once I'm comfortable with everything else.

Has anyone used this method to update to the March release yet? Can't see why it wouldn't work, since it's worked for all previous versions, but I thought I'd check before pushing the button. 😊

Based on what I'm reading, I'm sticking with PT 33.0.3. I guess there are still issues with 34.0.1 bricking phones.

Any know if it's still safe to use platform tools 33.0.3 with the April update? Hopefully it still works. 🤞

    Caution: I originally wrote this guide when it was necessary to disable verity and verification before flashing patched boot.img. Now Magisk has overcome this requirement and some users have reportedly flashed updates without disabling verification and verity and did not have to wipe their phones, but request everyone, who have verification and verity disabled and using this guide, make sure you backup all the data and post your results here (I suggest backing up data anyway for everyone).

    Following is a guide to update Pixel 6 Pro (perhaps all Pixel devices) every month, without wiping and retaining root. I tested it on my Pixel 6 Pro from 12.0.0 (SD1A.210817.015.A4, Oct 2021) to 12.0.0 (SD1A.210817.036, Nov 2021). There is no reason that it should not work on subsequent monthly patches, but just take the backups to be sure.

    1) Download the latest factory image for your device and platform-tools from the official Google site and extract them in one folder.

    2) Extract the boot.img from image-raven-xxxxxxx.zip which was extracted from the image in the above step and patch it in Magisk Manager (latest canary build from https://github.com/topjohnwu/Magisk) on your phone and copy it back to the folder where you extracted the factory image and platform-tools. Rename the copied file to magisk_patched.img

    3) Open flash-all.bat in notepad, add --skip-reboot and remove -w from the fastboot update line. Also add the following lines after the fastboot update line to flash the Magisk patched boot.img automatically:

    fastboot reboot-bootloader
    ping -n 5 127.0.0.1 >nul
    fastboot flash boot magisk_patched.img
    fastboot reboot

    After editing, the edited part of your flash-all.bat should look something like this:

    Code: 
    fastboot --skip-reboot update [****image_name****]
fastboot reboot-bootloader
ping -n 5 127.0.0.1 >nul
fastboot flash boot magisk_patched.img
fastboot reboot

echo Press any key to exit...

    Note: [****image_name****] is just a placeholder and needs to be the name of zip file which was originally there in flash-all.bat, do not change that. Be careful to rename the Magisk patched boot.img to magisk_patched.img or in the alternative make appropriate modifications in the flash-all.bat

    4) Open command prompt and go the folder where you extracted factory image and platform-tools. Type the following commands:

    adb reboot bootloader
    flash-all.bat

    Your device should be upgraded to the latest factory image, while retaining root, without wiping data.

    Update 1: I updated from 12.0.0 (SD1A.210817.036, Nov 2021) to 12.0.0 (SD1A.210817.037, Nov 2021) successfully using my method, without loosing data and root.

    Update 2: I updated from 12.0.0 (SD1A.210817.037, Nov 2021) to 12.0.0 (SQ1D.211205.016.A1, Dec 2021) successfully using my method, without loosing data and root.

    Update 3: I updated from 12.0.0 (SQ1D.211205.016.A1, Dec 2021) to 12.0.0 (SQ1D.220105.007, Jan 2022) successfully using my method, without loosing data and root.

    Update 4: I updated from 12.0.0 (SQ1D.220105.007, Jan 2022) to 12.0.0 (SQ1D.220205.003, Feb 2022) successfully using my method, without loosing data and root.

    Update 5: I updated from 12.0.0 (SQ1D.220205.003, Feb 2022) to Android 12L DP 3 successfully using my method, without loosing data and root.

    Update 6: I updated from Android 12L DP 3 to Android 13 DP successfully using my method, without loosing data and root.

    I don't know why folks continue to have issues updating when a new Android update is released. Despite Magisk having the option to install to an inactive slot for easy OTA updating, I simply avoid it and go the old-school route of updating via sideload to prevent any issues.

    In hopes of putting to rest issues some of you face, here is what I do:

    • Make a backup of all my important files in case something goes wrong
    • Disable any Magisk modules if it makes you feel any safer
    • Download the OTA image online and NOT from the system update!
    • Reboot to recovery and sideload the OTA by using:
    Code: 
    adb reboot sideload
    • Then, in recovery I load up the file by using:
    Code: 
    adb sideload "insert OTA file name here.zip"
    • Once it finishes, you will be in recovery mode. Select "Reboot to system now".
    • Once the system reboots, I unlock the device and let it finish completing the update before anything else.
    I then proceed to root the device as I normally would, by:
    • Getting the NEW boot.img file from the full factory image
    • Copy it to my mobile device
    • Open up Magisk and patch the boot.img file
    • Copy the patched file to my PC
    • Reboot into bootloader using:
    Code: 
    adb reboot bootloader

    Then, patch the new boot.img using:

    Code: 
    fastboot flash boot "patched_boot.img"

    Reboot / Done.

    I have not had it fail once using this process on stable Magisk and NO "disable" tags. The only reason I can see for anyone to use Canary versions of Magisk or "disable" tags, is if its absolutely required for some modules, ROMs, or kernels you are using. If it's not needed, just leave it alone.

    You could technically just dirty flash the entire full factory image using the Android Flash Tool or flash-all.bat script on your PC, but the script file is where I find most folks mess up because they copy and pasted instructions improperly, or there's a line of code they forgot to add or remove without proofreading before running the script. I'd rather take matters into my own hands, even if it means completing more steps to make sure things go smoothly.

    Anyway, I hope this helps someone!

    So I notice there are some people, like me, that are a bit confused on how to exactly do this process. I like to be nice every once in a while, so this is my time. I will try to do a step by step process with exactly how I did after reading, and re-reading all the comments on how to do it (with pictures cuz I need pictures to learn haha).

    These are the exact steps I took when I updated from .36 to .37

    I downloaded the .37 zip, the one for your phone, mine is an unlocked version.
    LaL2hSk_0qyLp5oaPEuURPDf5vItZ4YnlNFR2UPtQMRGIvceVoBc8nGvxpmu90RonBslivQblX8-YrygqYIrtbz1B7AvAPk8lKQ4z5jctSVh97hWwkzuO2kK2Os7doqxiUK-HJrx


    Slapped the .37 zip file into a folder by itself so I can extract it inside that same folder. It should look like this once its extracted inside the same folder.

    1637794601085.png


    Then I opened another folder/window with the Platform-tools so I can easily navigate between the 2 folders.

    Then I opened the flash-all.bat from the zipped folder, to see what it contains, noticed that it flashes 3 files/images.
    “bootloader-raven-slider”
    “radio-raven”
    “Image-raven-sd1a”
    b-Lrwcu7O5sU1Yges_LPc33ynTBNbVMki5KPtndnhgTLKp05njPQO_uoik6Tw11_tDyM7jCAlm0SjBbzK6b7MOkoKSOku9uhclnTclBZPDDfHumwjqLNrtHKRJ2yUoRf1B_y8EPW

    Then close the file as we dont need it right now.

    So with this I know that I will need to add those 3 files to the platform-tools folder when I go to actually run the command.

    I actually took the .37 boot.img and copied it into my pixel with version .36 still running.
    The boot.img is inside the zipped folder and when you extracted it, it will now be viewable along with other files and the zipped folder still there.
    1637794847696.png


    copy this boot into the main folder of the pixel
    1637795054884.png


    On your Pixel, open Magisk and click install then select patch file, navigate to the boot.img file in your internal storage.
    Patch it with Magisk and then take the patched boot.img (which that file will actually be in your downloads folder in your Pixel) and copied it back to my computer.

    So as of now, it seems we are able to patch boot.img with current build without having to update then patch then flash. We can just patch on the current build then copy the patch to the computer and run the rest of the steps.

    Now that I have the patched boot.img on my computer, I will take all the highlighted files in the picture, plus the patched boot.img over to the Platforms-tools folder and just copy them in that folder.
    Here, I’m not sure how everyone else has their folder since I rarely use those tools, so I just add the files and then delete them after I’m done flashing. See picture of all copied in files. (dont forget your patched boot.img)

    -Q2fqEHQmA5DPStoBV4ht9FVinUy7MD2GF4bi38EhGlItokhERTlrJAknwjGtSGXeMTVPnQn-6FZwXFqLJljCjYmrh3rYl4XPrDdLoyBO4QSOaaact8E2FvXwxjCZRfudWUgt_3m


    Now I will open the flash-all.bat that's inside the Platform-tools using Notepad ++ (personal preference).
    Edit this file exactly like in the picture. Add the lines exactly how it shows in the picture.
    **NOTE** that you need to type the exact patched boot file in there. So, like in this picture, but with YOUR patched "magisk_patched" file as this will have your own ID after 23014.
    1637734768289.png

    once you made the edits on this file, dont forget to save it before you run the commands!

    Now plug in your phone to the computer.
    Make sure you have USB debugging turned on.
    Press shift and right click inside the Platform-tools folder and open Command Prompt.
    run these 2 commands:
    adb reboot bootloader
    flash-all.bat

    When it's all done, your phone will boot up and you will be on the new .37
    Nothing else to add here as it will literally run through everything for you and boot up and you're done.

    Hope this helps someone, as I am a visual learner myself.

    couldnt we just add step 5 into the flash-all file? for example:
    fastboot reboot-bootloader
    fastboot flash boot magisk_patched-xxxxx.img
    fastboot reboot

    like in the picture? or would it not actually run that way?

    holy poop that worked!! i was scared to try it myself but since i have a backup phone with all my data on it, it wouldnt be so bad to wipe the pixel if i messed it up doing it this way! But hey, it actually worked!!
    here is the modified flash-all and yes you will need the "ping" line after the update line.
    1637619349812.png


    so with this, no need to type extra stuff, just add it all in the flash-all file and run the first 2 commands:
    adb reboot bootloader
    flash-all.bat

    and thats it, the only time consuming part is patching the boot, putting it in the folder with the platform-tools.
