TLDR: It's finally here in alpha form, may eat your data, and you will lose SuperSU root if currently installed. READ the install instructions carefully!

Pixel XL

Pixel

DO NOT RESTORE DATA FROM alpha builds of TWRP using RC1. You will probably lose all data including internal storage. If you need to restore a data backup from an alpha build, reinstall the alpha and restore using the alpha and make a new backup using RC1.

Note: Do not use if you have multiple users (including a guest user)

File Based Encryption (FBE) can be a bit tricky. If a restore doesn't work correctly, it can trigger an automatic wipe of your data. I've tested it a little on my Pixel XL, but I haven't had time to test it extensively. Sometimes TWRP will fail to prompt you to enter your password or otherwise fail to set up decrypt properly. If this happens, reboot TWRP. It seems to be some kind of timing issue and I haven't had time to track it down yet.

Pixel devices have 2 "slots" for ROMs / firmware. TWRP will detect whichever slot is currently active and use that slot for backup AND restore. There are buttons on the reboot page and under backup -> options to change slots. Changing the active slot will cause TWRP to switch which slot that TWRP is backing up or restoring. You can make a backup of slot A, switch to B, then restore the backup which will restore the backup of A to slot B. Changing the slot in TWRP also tells the bootloader to boot that slot.

The zip install method installs TWRP to both slots.

Installation:
If you already have TWRP installed: Download the latest zip and install the zip using TWRP.

If you do not already have TWRP installed: Download both the img and the zip. Copy the zip to your device. You will need to have fastboot binaries and the correct drivers installed. Power off your device completely. Hold volume down and turn on the device. Your device should now be in the bootloader. Connect the device to your PC. Open a command window and run the following command from the proper location:

fastboot boot path/to/twrp.img

This will temporarily boot TWRP on your device. If you are using a lockscreen pin/pattern/password and do not get prompted to enter your passord, reboot to the bootloader and try again. Go to install and browse to the zip and install the zip. If you are currently rooted with SuperSU, you will need to reflash the stock boot image before installing TWRP. After installing the stock boot image, follow the instructions for installing TWRP. Once TWRP is installed, grab the very latest SuperSU released on 2015-11-15 or later and install SuperSU.

If you accidently flash TWRP to your device using fastboot instead of temporarily booting the image, you will need to download the latest factory image for your device and reflash the boot image.

alpha2 should hopefully improve decrypt reliability.

RC1 supports true backup and restore of ext4 crypto policies on folders along with support for the newer style AB OTA update zips.

Why does installation of this remove SuperSU?
Aren't they supposed to be used side-by-side?
And it also warns not to install if expecting important calls.
Does it prevent the phone apps from operating or what?
I understand everything else.
