I have a weird issue where whenever I try to install twrp, it causes my phone to always reboot into recovery even when I choose system and I have to reflash the stock boot image and redo kernel and magisk. Seems twrp is screwing up the boot image. It's not a huge deal since I can just fastboot into twrp if I need to flash anything else... Just seems odd.

Thanks for the guide it worked great for me. The only issue I have is I want to flash some roms but I need to be on twrp 3.2.0 what is the easiest or best way to downgrade from 3.2.1 can I just fastboot the img. Then flash the installer or do I need to flash the factory image I am already on the latest version Feb update of Android if that means anything. I asked in the twrp thread but nobody answered me yet. Thanks in advance

i can't tell you why, but that happened to me a few updates ago. i flashed the full factory image but still had the notification that an update was available. i continued to use my phone as normal and the notification went away after a few days. hopefully it goes away for you after a few days.

Yes.

1. Go to this thread: [Guide] Pixel XL Android 8.1. 0 (OREO)...by Homeboy76
2. 8.1.0 Guide
a. Do #4 - Install Factory Image and keep or wipe data (Wipe data)
b. Tap #11 read notes a, b, and c.
c. Tap #11 read A and B, Choose the Custom ROM you want to install.
d. Tap #11, tap the link read the, entire, OP to learn the features, files you need to install it and how to install it. It is also a good idea to read the first five pages after the most recent update post. Why? If there are problems installing the latest update, they usually will be posted on these pages.

Good luck.

cannot access the "Developer Option" (to get to USB Debugging)

I cannot access the "Developer Option" (to get to USB Debugging) using this PixelDust Rom, no build number to tap on in System > About > .... Has this feature been moved under a different setting in the rom?

    [Guide] Pixel XL Android 8.0.0 (OREO) Unlock/Lock Bootloader + Install Stock Images/Custom kernels/TWRP Recovery/Systemless ROOT + November Security Patch
    Other Pixel XL Guides:
    Android 9.0.0 (Pie), Android 8.1.0 (Oreo), Android 7.1.2 (Nougat)    ​

    Intro
    This thread is for Pixel XL owners that want to Root their phone, and enjoy the benefits of rooting it without installing a Custom ROM. However, for those that just can't live without a Custom ROM, take a look at 'Custom ROMs for Pixel/Pixel XL'.

    This Guide also works for the Pixel: If, you download the correct files for the Pixel.

    Disclaimer
    I assume no responsibility for the malfunctioning/bricking of your phone.

    Prerequisites
    Need help installing Android SDK or using SDK Platform tools:

        • Note: If your computer only has 'open powershell here' in the context menu and you do not want to change it or add open 'command prompt here' use option 2.
      2. Boot Bootloader:
        • Power off phone, press and hold the power and volume down buttons until you see Start.
      3. Boot Recovery
        • Power off phone, press and hold the power and volume down buttons until you see Start. Use volume up/down button until you see Recovery mode. Press power button.

    I can confirm Homeboy's section "Root with SuperSU - Pass Safetynet" with the updated TWRP's and suhides fully works with October 2017 Patch. Latest update, Check. On device TWRP zip working in Android 8.0, Check. Root, Check. Hide root so you can use Android Pay and hide root from specific apps, Check. Best phone experience ever, and I'm happy to say Oreo battery life is great.

    Kind of....there are two ways to install Magisk.

    1. Use TWRP (either installed or booted into)
    2. No TWRP at all. Use the Magisk manager to modify boot.img and then fastboot flash the modified img.

    In either case installing TWRP, custom kernel and busy box would be optional.

    OTA function wouldn't work with custom kernel or recovery.

    That's my understanding!

    Actually

    3. Some are gaining root via #2 and then flashing magisk.zip via flash fire....for updates.

    Sent from my marlin using XDA Labs

    Click to collapse

    I forgot the Flashfire option (Damn, Damn, Damn :)) , thanks for the reminder.:good:

    I'll try all three so I have the facts straight before updating the OP. :):):)

    Edit: Testing complete, sticking with this method of installing Magisk 14.3:
    Install TWRP, Custom Kernel, Magisk, and Busybox


    Individuals wanting the OTA or Flashfire option can refer to Post 1 - #10 Root with Magisk, remain Stock, Pass SafetyNet and, Receive OTA Updates Thanks, LeMoise or Tips and Tricks - OTA Installation Tips

    im sorry to ask a stupid question like this. but im coming from the POS nexus 6P to the pixel XL. I've attempted to follow multiple websites for flashing twrp to the device, it seems theres a few variations around. is there not a twrp.zip available for the pixel xl? because the RC2 i tried from TWRP site does not work at all. either it just doesnt stick and i get the "no command" dead android screen, or it freezes at the main TWRP screen and never goes into the actual button choices.Did google essentially put a lock on the pixel devices so that we can't install a recovery zip on the phone like we could on all other google devices?. What if you're not near a computer and you have to do an emergency flash, backup, recovery or something else?
    also what is the deal with the slot A and slot B??

    thanks

    First, your questions are not stupid. Google, changed the game with the Pixel/Pixel XL. Fortunately, there are several XDA developer's that are working furiously to provide the tools needed to tame the Pixel/Pixel XL. They have built or modified Kernel's, SuperSU, Magisk and twrp to work with the Pixel/Pixel XL. Then Google changed the game again by upgrading the os from Nougat 7.1.2 to Oreo.

    The bright side is we have custom Kernel's and modded twrp and Magisk that work. The modded twrp has to be fastbooted every time you want to use it.

    Some have reported the installation of a Kernel and SuperSU via Flashfire (see #6).

    There are lots of article's that you can 'google' for a more in-depth answer to your questions.
