Pixel 2 Led Doesnt Continually Flash
- #1
Hello everyone, this is a guide to assist you with customizing your Pixel 2! I will be going over installing fastboot and adb, unlocking your bootloader, how to flash the factory images for clean flashes and upgrades, and how to root. Please feel free to ask any questions if you need clarification. Enjoy!
This information has been distilled from Google's official factory image site and the Magisk thread.
Installing fastboot and adb
Thankfully, Google has provided just adb, fastboot, and systrace as a simple zip file, making this process super easy. You MUST be on at LEAST 26.0.2 for the commands in this guide to work. When in doubt, grab the latest copy and install them using the following instructions.
- SDK Platform-Tools for Windows
- SDK Platform-Tools for Mac
- SDK Platform-Tools for Linux
Windows:
Mac/Linux:
Unlocking the bootloader
WARNING: This WILL wipe your entire phone. Please make copies or backups of any important data. This can also go wrong rendering your device inoperable. Proceed with caution.
- On your phone, open Settings, navigate to "System" then "About phone", and tap on the build number 7 times.
- Go one menu up, click on "Developer options", and turn on USB debugging and OEM unlocking.
- In your terminal, type the following command:
- Run the following command:
- Follow the prompts on your device then reboot!
Flashing factory images
NOTE #1: You CANNOT downgrade factory images. Google has prevented users from doing so to keep them safe from vulernabilities that were patched. You should only upgrade or reinstall the current image.
NOTE #2: If you have mounted /system as rw at any point (like in TWRP), you must upgrade using the factory image method. OTAs will fail because they cannot verify the integrity of the disk since its verity data has been changed.
NOTE #3: Flashing the factory images requires an unlocked bootloader. Flashing the OTA zips does not (but if anything goes wrong, you may not be able to recover without an RMA).
Updating to a new release (factory image):
Updating to a new release (OTA zip):Clean flashing a factory image (wipe everything):
Rooting with Magisk
NOTE #4: This section assumes you are not going to install TWRP. If you are, skip to the next section and just flash the latest Magisk zip after installing TWRP.
- Download the Magisk zip from the official thread and install the manager from the zip.
- Grab a boot image to patch (either the one from the latest factory image or a custom kernel one) and push it to your device:
adb push <path_to_file> /sdcard/Download - Open Magisk Manager and click the Install button.
- Click "Install" at the first prompt then choose "Patch Boot Image File". A file manager will pop up.
- Select the boot image you want to patch and let Magisk Manager patch it.
- Pull it off your device:
adb pull /sdcard/MagiskManager/patched_boot.img - Reboot into the bootloader:
- Flash the boot image and reboot.
fastboot flash boot patched_boot.img fastboot reboot - Open Magisk Manager and you should be rooted!
Installing TWRP
NOTE #5: If you just want to temporarily boot TWRP to flash Magisk and your custom kernel, you can just skip flashing the installer zip in this process.
NOTE #6: TWRP can be unstable at times given the way that security has been set up on this device (lack of decryption, failing to boot, etc).
- Download both the TWRP image and zip installer from the official site.
- Temporarily boot the TWRP image.
fastboot boot <path_to_twrp_image> - Flash the TWRP installer zip.
- Reinstall Magisk and your custom kernel if you had them.
- Reboot and profit!
Common issues
- Outdated fastboot/adb: This device requires the latest fastboot and adb binaries to work properly. A lot of common quick adb/fastboot installation guides link to installers that are old. Please manually install the latest using the information at the beginning of the thread!
- Using a USB-3.0 or USB-C port: Some newer USB ports do not work with fastboot. Issues manifest as weird errors during a flash. Use a different USB cable/port.
Closing statements
If there are any procedures you would like to see added (like flashing a custom kernel or booting TWRP), I am happy to add them if requested. Also, when requesting help, please be as specific as possible where you get confused. I want this guide to be clear as possible.

Run the flash all script! Open a command prompt, navigate to the folder with the script, and run one of the following commands:
How do I navigate in command prompt? When I typed flash-all, it said it is not a internal command etc. When I dragged and dropped flash-all into the command prompt, it said C:\Users\W Balls\Downloads\SAMPWND_SYSTEMROOT_ADB_FILES>"C:\Users\****** Jim\Downloads\walleye-opd1.170816.025-factory-4752baae\walleye-opd1.170816.025\flash-all.bat"

First, thanks for putting this together. I've rooted using your method.
Regarding OTA updates: I've read that if we've rooted, we will need to un-root before we can receive an OTA update. Is this always true, or only if we've installed a custom recovery like TWRP? It would be really handy to have a guide on how to un-root, update, then re-root.
Related - let's say that for whatever reason, we have to flash an OTA update manually, rather than actually getting it OTA. Do we lose root by doing so?
Thanks!

Magisk's OTA section should clear up some of your doubts: https://github.com/topjohnwu/Magisk/blob/master/docs/tips.md#ota-installation-tips

Looks really straightforward, thank you! Might be cool to point to it in the OP. I bet I'm not the only one who was only vaguely aware of the impact that rooting has on how we get OTAs. Then again, maybe everyone else wants to run custom ROMs.

Good point, I'll add it here in a bit

Howdy,
really appreciate @nathanchance for putting this together. Would you mind adding a few lines about the differences between OTA and factory images. As a layman i haven't got the foggiest idea which route to go and would appreciate some wisdom. Thanks!

The primary difference is that the OTA can be flashed on an unlocked bootloader and is designed not to wipe your phone.
Thank you so much for this guide but can anybody please explain how you can tell which image to patch ?

Are you supplying the boot image to Magisk? Show me a screenshot of what Magisk says when it tries to patch.

All I ended up doing is taking the OTA from Google to the .025. Then followed the Magisk rooting instructions to get root. I had Unlocked it the first day I turned the phone on, I haven't put my SIM in yet, but will play around with it a little more, and finish setting it up,
Again, thanks for the GUIDE to this Pixel 2 phone.

That is what i get. I have even flashed the whole factory image to the phone and still get this

1. Download and extract factory image. Mine was taimen-opd1.170816.010-factory-c796ddb4.zip ---------- Post added at 08:36 AM ---------- Previous post was at 08:27 AM ----------
***2. Once extracted go into the folder and extract image-taimen-opd1.170816.010.zip.
There you will find the boot.img.

@nathanchance, one more suggestion for the OP: at one point I was looking at using the stock boot img and couldn't figure out how to get it. Later, I found the below post, where the first two steps are essentially "open the zip inside the zip for the boot.img" to extract the stock boot image. Maybe it's really obvious, but I didn't get it.

this is where i was going wrong i was using a file that had bootloader in the name rather than going into the second zip and finding boot@nathanchance, one more suggestion for the OP: at one point I was looking at using the stock boot img and couldn't figure out how to get it.
