Yes you can do it that way.Going to dust off my Pixel 2 XL and play with this. It's currently running an ABC rom (Pie). Can I use flash.android.com to go to DP2? I don't care about clean vs dirty flash since this is not my daily driver any more.
1. NoIf I install using android flash tool :
Will the bootloader be locked after install
Will I get public beta update as OTA
1. YesCouple questions
1. Will you loose twrp if I install?
2. Is there any root for Android 11?
You can't.How do I install it without having the bootloader unlocked?
Don't use flash tools.i cant install this on my phone for the life of me. I finally got my phone back on and set up, tried a fresh download and install still isnt booting. Stays on the black google screen. Also i notice that when i first flash it on the first reboot after the script is finished, i get the red device is corrupt screen.

Yep i did all of that. Sideload isnt working, says it cant read the zip and im on an unlocked bootloader. Only used flashtools after everything else wasnt working and a google search said that using flashtools could maybe get the sideload to work.Don't use flash tools.
Download the image.
Enter recovery mode (go to bootloader screen (hold power and volume down or use ADB to reboot to bootloader),choose recovery and when it says "no command" hold power and press volume up key briefly, sound say something about sideload at the bottom, sideload the image from your computer with ADB by using the command
"ADB sideload 'filename'.zip".
I renamed the DP image 'OTA'.zip to make it easier.
Keep in mind with locked bootloader there is no known way to downgrade at the moment.. Only up. I tried to downgrade every way I know so far and no dice.
