Boot-To-Root Boot-Loop

[diablopants]

My setup
Pixel XL from Verizon
Bootloader unlocked
Bootloader Version 8996-0121001-1611091517
Baseband 8996-012511-1611190200
Android 7.1.1 NOF26V
Kernal 3.18.31-g367e645 Dec 7, 23, 2016
Twrp Version 3.0.2.0 RC1

I have tried following this guide to get root access https://www.xda-developers.com/root-is-now-available-for-the-google-pixel-and-pixel-xl/


My steps are
1. boot phone into fastboot
2. from pc run fastboot boot boot-to-root.img
3. the phone reboots
4. Phone is stuck with the 4 colored dots jumping over each other
5. i've given this screen up to 30 minutes with no results.
6. Forcing a reboot causes the same issue
7. Flash stock android via the official google factory image method

I have attempted this other method as well http://www.theandroidsoul.com/root-pixel-xl-magisk/
But after TWRP says it's successful, i boot into my OS and there is no supersu and if i manually install supersu, it says no root access.

You are doing it the old way that was for 7.1.

You want SU 2.79 SR3

And you want TWRP RC1.

I would not install TWRP at this point. So copy SU to your phone. Then boot to TWRP.

Fastboot BOOT twrp.img

With twrp.img being the correct name of the file. Then in TWRP install the SU you copied.

The old way... Sheesh, there's only so much space up here. But thank you. You've saved be a big headache when my XL finally arrives.

Edit: you boot TWRP, not flash through fastboot?

You boot it, always.

If you want to install it you copy the twrp ZIP to the phone. Boot it with the TWRP image file then install the twrp zip from within twrp.

Gotta be done that way. Partition layout has changes, they are a bit intertwined now.

I dont install TWRP anymore.

That was half the fun not needing a PC to flash a ROM.
I see I'll be reading. A LOT before it gets here.

That might be doable, I am not a ROM guy. Root and kernel only....and I always got a PC.

so I would just want to pull down the twrp RC1 image file, boot from fastboot without flashing it, and use it to flash the SU SR3? All i want is root access at the moment on the pixel XL.

if i understand this right, this will just give me SU with root, and not install any form of TWRP.

Exactly.

You don't need a PC if you just install TWRP.

Exactly.

will i need anything more than ADB? I used depixle8 via ADB to unlock my bootloader.. i assume its just the same to push the files through or am i missing something?

What files are you pushing that you cannot just load directly with the device powered up?

You will need fastboot, so you can fastboot boot twrp. I don't push the SU zip with adb, I just copy/download it to the phone before I reboot into Fastboot. Make sure you get Fastboot from Google, not the Minimal one.
