How to Flash DivestOS on Pixel Devices and Relock Bootloader

The below process will wipe off all the data from your device, so please take a complete device backup beforehand. Droidwin and its members wouldn’t be held responsible in case of a thermonuclear war, your alarm doesn’t wake you up, or if anything happens to your device and data by performing the below steps.

NOTE: Relocking the bootloader is a highly risky approach and could result in a bootloop or even a bricked device. So if you don’t wish to take any risk, then it’s better to leave the bootloader unlocked. On the other hand, if you wish to relock the bootloader, then make sure to keep the OEM Unlock toggle enabled at all times. This is because if something goes wrong, then you can boot your device to Fastboot Mode, unlock the bootloader, and flash the firmware to unbrick it.

1. First off, download DivestOS for your Pixel device from below: DOWNLOAD LINK
2. Download and extract Android SDK Platform Tools on your PC.
3. Now enable USB Debugging and OEM Unlocking on your device.
4. After that, unlock the bootloader via the below command: fastboot flashing unlock
5. After that, open Command Prompt inside the platform-tools folder.
6. Now type the below command to boot your device to Fastboot mode. adb reboot bootloader
7. Then verify that you are getting a serial ID via the below command: fastboot devices
8. If you aren’t getting any ID, then install Fastboot Drivers on your PC.
9. Now do a format data via the below command: fastboot -w
10. Then download the AVB key for your device [avb_pkmd.bin] from below DOWNLOAD LINK
11. Now use the below command to erase the existing AVB key: fastboot erase avb_custom_key
12. Then type in the below command to flash the new custom AVB key : fastboot flash avb_custom_key avb_pkmd-device.bin
13. Now reboot to bootloader via the below command fastboot reboot bootloader
14. Rename the ROM to rom.zip and transfer it to the platform tools.
15. Now flash the DivestOS ROM on your Pixel via the below command [make sure to flash the Fastboot Version]: fastboot update rom.zip
16. NOTE: If you receive a board mismatch but are sure you have the right file, then try the below fixes: FIX 1: fastboot update –force […].zip FIX 2: edit the android-info.txt file in the .zip file to match your board
17. Once the flashing is done, your device will boot to the OS. Make sure to re-enable USB Debugging.
18. NOTE: The below steps 19 to 23 are only required for devices that have a custom recovery. Since Pixel devices don’t have one, therefore, we have chalked those steps below. You should start off with STEP 24.
19. Once the flashing is complete, reboot to recovery via the below command fastboot reboot recovery
20. Then select “Apply update” > “Apply from ADB”.
21. Now type in the below command in the CMD window to sideload the ROM [make sure to sideload the Recovery version] adb sideload rom.zip
22. Once the flashing is done, do a Factory Reset from the recovery.
23. After that, select Reboot System Now to boot your device to the newly flashed OS.
24. We will now start with relocking the bootloader. Proceed with caution!
25. First off, enable USB Debugging and then type in the below command to boot your device to Fastboot Mode: adb reboot bootloader
26. Next up, verify the relocking eligibility: fastboot flashing get_unlock_ability
