OTA updates: The builds are in OTA format so they dont include bootloader and radio images so make sure you have flashed latest bootloader and radio image from google stock images bootloader-raven-slider<version>.img radio-raven<version>.img First time install: Bear with me that I simply dont care about Windooze users here just google for any specific instructions there. Also I will skip anything regarding bootloader unlock here and assume you did this before. Extract file payload.bin from <ota-file>.zip Use payload dumper to extract boot.img and vendor_boot.img from that payload.bin file There are different impls of payload dumper eg https://pypi.org/project/payload-dumper/ https://github.com/ssut/payload-dumper-go Make sure you use the latest version of Android SDK platform tools https://developer.android.com/studio/releases/platform-tools Make sure you are familiar with basic usage of fastboot and adb commands If you care about anything on the device - NOW its the time to create a backup somewhere save Test adb working: > adb devices List of devices attached <serialnumber> device Reboot into bootloader: > adb reboot bootloader Check fastboot showing device in fastboot mode: > fastboot devices <serialnumber> fastboot Flash minimal recovery: > fastboot flash boot boot.img > fastboot flash vendor_boot vendor_boot.img Start recovery: > fastboot reboot recovery Wait until you see Android mascot on his back with the words 'No command' underneath. Press and hold the Power key and then press the Volume up key once while still holding down the Power key.
