Rooted and TWRP Recovery, how do I update OTA? Please help! Google Pixel XL

[DrixlRey]

I've searched the forums but nobody has answered the questions yet, I'm not familiar with entering the commands, please tell me what I'm suppose to do step by step. I know ADB but when people say flash the firmware, I'm not quite sure what I type or mean.

I was able to sideload the OTA with TWRP RC1. My understanding is this doesn't work on the alpha versions.

1. go here and download the OTA (the file ending in 26O is the Verizon version)
2. Boot into TWRP
3. Select "Advanced" then "ADB Sideload"
4. Run the command adb sideload <file you downloaded>
5. If you have a custom kernel, you will need to re-flash it
6 Reboot your device(first boot will take a while)
7. ???????
8. PROFIT

when i click advanced and adbsideload it gives me two options one is to wipe dalvik the other is to wipe cache then at the bottom it says swipe to start sideload ( i havent selected any files or ran a command for it to sideload anything)

those steps are optional, just swipe to start then you can run the adb side load command.

an important thing I forgot to add is that in addition to having to re-flash a custom kernel is you'll also need to re-flash TWRP and likely re-root (I am not rooted so I can't be sure). I'd recommend waiting until after the first boot to do that just to make sure everything comes up OK.

Not sure this saves as much time as it could. I had not updated from the x build yet, so after installing RC1 and SU 2.79 I figured why not try the TWRP sideload. It worked (though I originally tried the Q build which showed a file validation failure I used O), but sideload changes your slot. In my case, it cleared the slot of the recovery and got rid of root access. I had to temp fastboot the TWRP .img and then install the TWRP zip. I then reinstalled SuperSU as well. All's back to normal now.
