How To Guide September 12, 2022 Verizon factory image (TP1A.220905.004.A1) - PSA about Android 13 in OP - Unlocking the Pixel 6 Pro bootloader & central repository

Search This thread
Yes. However I wasn't able to update via automatic OTA on my Pixel 5.
Yeah I updated to the last 12 build and then tried seeing if it would OTA to 13 but wouldn't so I just re-rooted. I already pulled the 13 zips but wanted a definitive answer before I tried that. Will likely do it sometime tomorrow.

You are correct.

I did:

Code:
adb reboot bootloader
fastboot flash bootloader bootloader-raven-slider-1.2-8739948.img
fastboot reboot

And I'm booted into Android 12 still just fine. Below is the command prompt output:


Note to anyone, if after upgrading to 13 you want to downgrade to 12 using a full factory image's flash-all.bat, you'll at minimum have to either remove Android 12's bootloader flash line from the file, or replace it with fastboot flash bootloader bootloader-raven-slider-1.2-8739948.img (and have the right bootloader file in the same folder). Either should work fine.
Let's just hope that ARB is only tied to downgrading to the A12 bootloader and not other parts of the OS as well.

Google's statement wasn't exactly clearcut in my mind. I think a bad result could potentially lead to a more than undesirable outcome, if you know what I mean. Of course, I could just be overly paranoid 🙃

So when factory installing through flash-all, the default installation of A13 is to one slot and not both?

Haven't seen anyone get V4A working on A13 on the Pixel 6 series. JamesDSP, however, does work.
Quick question, do you know if JamesDSP automatically switches audio profiles when you connect to different audio devices like V4a does? Currently using V4A and contemplating trying out JamesDSP just so I can update to Android 13 lol

So what is the correct way to install it to BOTH slots, before booting into the system?
After flashing to your active slot, just change slots and flash again.

Unrelated device, but with A/B slots:
fastboot --set-active=a
If you're on slot b
fastboot --set-active=b
If you're on slot a

You can see which slot you were already active on after adb reboot bootloader (on the Fastboot screen) three items from the very bottom it will say:
or

The change slot command reflects immediately on that screen.

I just did all this.

This is correct. I actually did this when updating to A13 stable so I would have A13 on both slots in case things got funky. Confirmed 👍

I'm sorry. I don't want to screw it up.
Do I use the official android flash tool? Is there an option there to reboot into inactive slot or do I need to use fastboot/adb to update to A13.
I only used adb to update monthly. Thanks.

I actually can't say for sure since I really don't use any profiles, but I think it does.

I use the full Pixel 6 Pro Factory Image to update each month. Use the same official latest ADB/Fastboot (SDK Platform Tools) you normally use. Edit the flash-all.bat (if on Windows - if on something else, edit the appropriate flash-all script file) and remove the "-w" and re-save it. If you want to keep the flash-all.bat from rebooting automatically after the update so that you can change slots and flash again, add fastboot --skip-reboot in the flash-all.bat after the fastboot update image-raven-xyNz.YYMMDD.BBB.zip line. Thanks, @Homeboy76 and @Lughnasadh!

Re-open the script file and confirm that you saved it with the "-w" removed, so it doesn't wipe your device.

From running Android:
Code:
adb reboot bootloader
(Let it reboot into Fastboot mode.  Make note of which active slot is listed on the Fastboot screen, third item from the bottom.)

flash-all.bat
(WITH "-w" removed.  Let it flash everything, will take several minutes.)

Let it boot up (and check the notifications for the update process to finish while Android is running)

adb reboot bootloader

On the Fastboot screen, change to the opposite slot with either:

fastboot --set-active=a
(If you're on slot b)

OR

fastboot --set-active=b
(If you're on slot a)

OR

[QUOTE="Homeboy76, post: 87298957, member: 4810220"]
I think you may want to use
[ICODE] fastboot --set-active=other[/ICODE]
it lowers the mistake threshold.
[/QUOTE]

flash-all.bat
(again)

I used the flash-all method. I was on slot b so I flashed A13 on it and let it boot up (I removed the -w from the flash-all.bat script beforehand to preserve data) Then went into fastboot and switched slots and flashed the factory image again and booted. Now booted on slot a with both slots having A13 on them. That's it.

Oh okay, thanks. I assumed you went straight from flashing the one slot to flashing the other slot. :)

    This thread confuses me. Can one root a device that is currently sim locked?
    SIM locking, which locks your SIM card to your device, i.e. can't move that same SIM card with another device, is not the same as being Carrier locked. The ability to lock your SIM card to your device is controlled by you only - by default, SIM cards are not locked to the device. You can use the search field in the device Settings to find "SIM card lock", which is in the "More security settings" submenu.

    As the others have said, Carrier unlocking and having the ability to bootloader unlock are two separate things, but typically if a device is not carrier unlocked, then you are also not able to unlock the bootloader. Being carrier unlocked does not necessarily mean you can unlock the bootloader. Example 1: Verizon. Example 2: All Samsung devices bought in the United States that can have mobile data connections. Samsung WI-Fi-only tablets can be bootloader unlocked (at the cost of tripping KNOX permanently), but obviously, in that case, there's no carrier involved.

    Looks like they finally updated the "Updating Pixel 6, Pixel 6 Pro, and Pixel 6a devices to Android 13 for the first time" section on the download page to include the correct command for Option 2 (adb reboot bootloader rather than adb reboot fastboot).

    @roirraW "edor" ehT Thank you, I was just curious in case a situation appeared again where I needed to have both slots the same (I like to ask before I get stuck up a creek w/o a paddle).
    You're welcome. Understood.

    Just at minimum do (and you should do first thing):
    Code:
    fastboot flash bootloader --slot all bootloader.img
    And that'll prevent you from getting stuck. Not doing that, you could wind up being bricked to a point where only Google could repair the phone.

    Regarding Developer Support Android 12 images, see @Lughnasadh's post here.

    I am not linking directly to the Developer Support Android 12 images because I don't want them to be confused with Stable Android 12, and since the Developer Support images won't receive any OTAs...ever. They likely also will never be manually updated on the Developer Support images site, so they will forever be stuck with the security patch level they're currently on, which will become further out of date every month. You can Google search Developer Support Android images if you want to find them.

    Platform Tools has been updated slightly to v33.0.3:

    Windows: https://dl.google.com/android/repository/platform-tools-latest-windows.zip

    Mac: https://dl.google.com/android/repository/platform-tools-latest-darwin.zip

    Linux: https://dl.google.com/android/repository/platform-tools-latest-linux.zip

    Release Notes https://developer.android.com/studio/releases/platform-tools:

    33.0.3 (Aug 2022)​

    • adb
      • Don't retry adb root if first attempt failed.
      • Fix track-devices duplicate entry.
      • Add receive windowing (increase throughput on high-latency connections).
      • More specific error messages in the "more than one device" failure cases.
      • Reject unexpected reverse forward requests.
      • Fix install-multi-package on Windows.
    • fastboot
      • Remove e2fsdroid as part of SDK platform-tools.
      • Print OemCmdHandler return message on success.

    TL;DR regarding the PSA. If you update one slot to Android 13, you can fastboot reboot bootloader after and then fastboot --set-active=other to change slots in order to flash Android 13 to the new slot, but IF you have Android 13 on one slot and still have Android 12 (including Android 12 bootloader) on the other slot and you try to fully boot into Android 12, you will be permanently bricked and have to seek repair from Google. No one has yet found a way to repair this on our own. I will update if there is any progress. At least a small handful, and probably more, people have done this already.

    At a minimum, do this first: fastboot flash bootloader --slot all bootloader-devicename-slider-1.2-3456789.img (change the name of the bootloader file to the one for your device), then you *should* be much safer than without doing that first. Also note that the bootloader is NOT the same as boot.img (kernel). The bootloader image file has "bootloader" in the filename.

    IF you have already bricked your phone and the screen is blank - there is likely nothing we can do to help. You should seek to get a repair from Google, possibly under warranty.


    You CANNOT go back to Android 12 Stable. It *seems* as if you can, but Android 12 will not work 100% correctly after updating to the Android 13 bootloader.

    My tiny, early, very mini-review of Android 13 is here.

    Note that this is mainly for the officially listed "Unlocked" Pixel 6 Pro, available directly from the Google Store. All of this will also apply to any other (carrier-specific) variant of the Pixel 6 Pro which you can achieve an unlocked bootloader on. This includes T-Mobile and AT&T variants. It's likely Verizon variants will never be able to unlock their bootloader, or if so it will require paying the right person to do so.

    Feel free to ask about general questions, but for anything that's specific to your variant, you should use one of the other already existing threads. You'll find Verizon, AT&T, and T-Mobile-related threads in those respective search results.

    Here there be dragons. 🐉 I am not responsible for anything at all. 😹

    Unlocking or locking the bootloader will wipe the device every single time, so be sure to have your data backed up before doing so, or better yet, just unlock it as soon as you get the device.


    Keep in mind that unlocking the bootloader or rooting might affect your phone's capability to use banking apps such as Google Pay, your local bank's app, or even the ability to install some apps like NetFlix. See @Pekempy's thread Working SafetyNet with Pixel 6 Pro Android 12

    If you're going to re-lock the bootloader, make sure the ROM you have on your phone is completely stock (by flashing the latest official firmware) BEFORE re-locking it.

    There are no negative consequences if you unlock or re-lock the bootloader other than it will wipe your phone, and while unlocked you get a brief screen when you boot the phone telling you (and anyone who sees your phone at the time) that the bootloader is unlocked. You will also continue to receive updates (if you've merely unlocked the bootloader, you can take updates as normal) unlike Samsung, Sony, et cetera, which have permanent major consequences with reduced functionality even if you un-root and re-lock your bootloader. If you're actually rooted (not just bootloader unlocked), you'll have to perform extra steps to manually update each month, and to keep root/re-root.


    All posts about Google Pay or banking will be reported to be deleted. Please keep this thread on-topic. There are at least one or two other How To Guide threads in this section in which folks discuss how to get around banking app restrictions when you're rooted or just have an unlocked bootloader. See @Pekempy's thread Working SafetyNet with Pixel 6 Pro Android 12
    If users persist in discussing banking apps in this thread, I will have this thread locked and only update this first post when there is new and updated information regarding the subjects of the title of the thread: Unlocking the Pixel 6 Pro bootloader, rooting, and TWRP. See @Pekempy's thread Working SafetyNet with Pixel 6 Pro Android 12

    Honorable mention to @Jawomo's aodNotify - Notification Light / LED for Pixel 6 Pro! (XDA link) / Notification light / LED for Pixel - aodNotify (Play Store link), which in my opinion restores useful functionality missing in most phones these days. It also solves some subjective issues some folks have with AOD (Always On Display), and/or solves/works around the problem where AOD is required for the optical fingerprint reader to work without the screen being on.​


    Check warranty status - *may* reveal if a phone is refurbished, only if the phone was refurbished through Google - thanks to @Alekos for making me aware of the site.
    Official Google Pixel Update and Software Repair (reported as of January 23, 2022 to still not be updated for the Pixel 6/Pro yet)

    Google's Help Page for Find problem apps by rebooting to safe mode - this can be a lifesaver and keep you from having to do a restore to 100% complete stock or even from having to do a factory reset. This will deactivate all Magisk modules, and they'll remain deactivated even after you boot normally after briefly booting to safe mode. You can reenable the Magisk modules as you wish to try to narrow down the problem if it was caused by a Magisk module. This can even get things working again after a Magisk Module wasn't finished installing and potentially causing a bootloop.

    Official Google Pixel Install fingerprint calibration software (also available at the bottom of the Update and Software Repair page above) - I believe this is only helpful if you've replaced the screen
    Official Google Android Flash Tool (OEM Unlocking needs to be toggled on - you may not have to manually unlock the bootloader - the "site" will do that on its own)
    OEM unlocking in developer options needs to be toggled on. I don't "believe" you have to actually do the "fastboot flashing unlock" command.

    ADB/Fastboot, Windows Drivers, and unlocking the bootloader (thanks @sidhaarthm for confirming unlocking the bootloader works as intended, be sure to thank him in his post)
    • You'll need this if you're going to unlock the bootloader on your Pixel 6 Pro: SDK Platform Tools (download links for Windows, Mac, and Linux). Note that you can find links to download the tools elsewhere, but I wouldn't trust them - you never know if they've been modified. Even if the person providing the link didn't do anything intentionally, the tools could be modified without them being aware. Why take a chance of putting your phone security further at risk?
    • For Windows, get Google's drivers here Get the Google USB Driver (ADB will likely work while the phone is fully booted, but if you're like me, you'll need these drivers for after you "adb reboot-bootloader", to be able to use ADB and Fastboot.
    • Thanks to @96carboard for posting the details of unlocking the bootloader, be sure to thank him in his post. Unlocking or locking the bootloader will wipe the device every single time, so be sure to have your data backed up before doing so, or better yet, just unlock it as soon as you get the device. Keep in mind that unlocking the bootloader or rooting might affect your phone's capability to use banking apps such as Google Pay, or your local bank's app. If you're going to re-lock the bootloader, make sure the ROM you have on your phone is completely stock (by flashing the latest official firmware) BEFORE re-locking it. My experience on my Pixel 1 was that there were no negative consequences if you unlock or re-lock the bootloader other than it will wipe your phone, and while unlocked you get a brief screen when you boot the phone telling you (and anyone who sees your phone at the time) that the bootloader is unlocked. All of this should still be the case. You will also continue to receive updates. Unlike Samsung, Sony, et cetera, which have major consequences with reduced functionality even if you un-root and re-lock your bootloader. If you're actually rooted (not just bootloader unlocked), you'll have to perform extra steps to keep root/re-root.:


      The unlock process works like this:

      1) Take brand new fresh phone out of box. Do NOT put sim card in it, just power it on (you can put a SIM card if you want, you just don't have to).
      2) When it starts harassing you to join Google, hit "skip" and "remind me tomorrow" as applicable until you reach home screen. YOU DO NOT need to plug in a google account.
      3) Settings --> About --> Build number. Repeatedly tap it until it says you're a developer.
      4) Back --> Network --> WiFi and connect it.
      5) Back --> System --> Developer --> OEM unlocking (check), USB debugging (check), plug in USB, authorize on the phone when requested.

      Using the Platform Tools previously mentioned in command line/terminal:
      6) #
      Code:
      adb reboot-bootloader
      7) #
      Code:
      fastboot flashing unlock

      Now that you've unlocked it, it has been wiped, so repeat 1-4, then disable all the google spyware, and go ahead and start using it while waiting for aosp and root.

      Official Instructions for Locking/Unlocking the Bootloader
    Personally, I would always use the official drivers Google provides unless they just don't work for whatever reason: Get the Google USB Driver (this is for Windows). They work for me. They are rarely updated, but they are every once in a great while, sometimes years in-between.
    I agree with this. be careful using drivers or adb/fastboot tools. Some are fine, but there's no need for it really anymore. Google has made it very easy to install drivers and Platform-Tools (adb/fastboot tool).

    Google provides the Fastboot/ADB tool (Platform-Tools) and Google USB Drivers (adb/fastboot interface). This will allow any Pixel to interface with Windows using the fastboot/adb protocol. Official Google USB Driver includes support for both the Fastboot and ADB driver interface. There are 3 main drivers (Fastboot, ADB and MTP/Portable File Transfer). The MTP/Portable File Transfer driver is built-in to Windows 7-11.

    Fastboot/ADB Driver Interface - Official Download Link:
    When flashing a full image or unlocking your bootloader, the fastboot interface is being used.

    First Download official Google USB Drivers (it's a zip file). Extract the zip (important!). Right-click on the android_winusb.inf file and hit install. You can then restart your phone to the Bootloader Screen (hold vol-down while it restarts or turns on). When you plug in your phone, Windows Device Manager will show a new device at the top: Android Device: Android Bootloader Interface.

    Using the ADB interface: It's the same driver. Enable USB Debugging on your phone, then plug it in to your computer. A prompt will appear on your phone (to allow USB Debugging). The driver in Device Manager will appear as Android Device: Android Composite ADB interface.

    Now you can download and use Platform-Tools to flash an Android Image, OTA or run adb/fastboot commands.
    Official Download Page
    "Android SDK Platform-Tools is a component for the Android SDK. It includes tools that interface with the Android platform, such as adb, fastboot, and systrace"

    It's best to make Platform-Tools available system-wide. Download Platform-Tools from the above link and extract it to your C:\ drive - that way you will have a folder to add to the PATH Environment under Window System Properties Menu, Advanced, Environment Variables, System Variables, PATH (google how to do this, very easy). What this does is allow adb/fastboot commands to be run from anywhere in the system, so you don't have to be in the platform-tools folder to run adb/fastboot commands and flash an Android Image (Official or Android Fork such as ProtonAOSP).

    Rooting-related


    No longer applies - Things that make rooting more complicated on Android 12
    @V0latyle posted a new thread with some very important and fascinating information about the increased difficulty to root Android 12: Read this before rooting. Be sure to thank him there.

    A list of the other important guides - be sure to thank the respective OPs
    For all relevant guide threads just click the yellow "How To Guide" quick filter above the list of threads in the Pixel 6 Pro section.


    TWRP (not made for the Pixel 6 Pro yet - will update when it has)
    I would guess that this should be the appropriate URL for official TWRP custom recovery for the Pixel 6 Pro, but who knows when/if that will actually be made available, and it may become available unofficially in these forum sections before being made official. I'll adjust this URL as needed. https://twrp.me/google/googlepixel6pro.html.

    Custom kernels for stock ROM(s)

    Factory Images (requires an unlocked bootloader)
    It's also handy to have to the full official firmware available, whether it's to recovery from accidents or for actual development. Note the official link to the general Factory Images for Nexus and Pixel Devices page. The following link goes directly to the Pixel 6 Pro (Raven) section: Pixel 6 Pro Factory Images. I prefer to actually bookmark a link to the device listed immediately below the device I want the firmware for, because Google dumbly (in my opinion) puts the latest firmware at the bottom of the list for each particular device, and that ends up making you scroll a lot after a year or two of monthly updates.

    Note: You can still get the December 2021 Factory Images and OTA from this thread, if you need them for any reason: Alternate links to December - all full factory images and OTAs available

    Full OTA Images (doesn't require an unlocked bootloader)

    The usefulness of having Verity and Verification enabled (now that it's not needed for root) - post #2 below.

    Regarding P6P 5G model numbers and capabilities - post #3 below.

    List of all Pixel monthly security bulletins and Play System Updates - post #4 below.

    How I root and update (which is identical whether rooting the first time or updating):
    • Use the latest Magisk Stable (in my case, I keep the app "hidden" / renamed)
    • Used the full firmware zip, extracted to the same folder as the latest Platform Tools (S:\platform-tools)
    • Extracted the new boot.img
    • Copied new boot.img to the phone
    • Patched the new boot.img with Magisk Stable
    • Renamed Magisk'd boot.img so I know what version of firmware it's for
    • Copied the Magisk'd boot.img back to the computer
    • Disabled all my Magisk Modules
    • Removed the "-w " from the flash-all.bat
    • Re-edited the flash-all.bat to verify I saved it with the "-w " taken out
    • Open a Command Prompt, navigated to S:\platform-tools
    • adb reboot bootloader
    • flash-all.bat
    • Let phone boot, unlock it, check that it's working, allow the update process to finish (gave it five minutes or so)
    • adb reboot bootloader
    • fastboot flash boot kernel.img (renamed Magisk'd boot.img)
    • fastboot reboot
    • Unlock, check everything's working
    • Re-enabled the most basic Magisk Modules which I was sure wouldn't cause a critical issue
    • Reboot, unlock, made sure everything's working
    Back to modding!

    I may append these first four posts with further useful information or links as needed.

    Just to let everyone know, updating to .037 and re-rooting (without wiping anything) worked with no problems. My method is to just replace -w with --disable-verity --disable-verification in the flash-all.bat file and run the flash-all command. I then let it reboot, patch the boot image, return to bootloader and flash the patched boot image.

    Canary 23014

    EDIT: Thank you @ipdev for confirming my inquiry that this method would work back on Nov. 4 👍
