Pixel 6 Pro [Raven] QPR Betas
QPR stands for "Quarterly Platform Release". Android 13 QPR3 went final in June 2023. See main thread here for final/non-beta releases.
From my Pixel 7 QPR Beta thread (and adjusting the OP with the same information):
I don't know for sure, but I suspect that no one can opt into the QPR3 Beta program any longer.
Even Google's QPR3 Beta release page:
and leads to:
the Enroll in Android 13 Beta for Pixel button there still leads to:Get an Android 13 on your eligible device.developer.android.com
which only mentions Android 14 Beta.Android Beta Program allows you to enroll your Android device for beta releases.www.google.com
So I think your only choice if you want to try QPR3 Beta is to have an unlocked bootloader and flash the factory image, or I think it's possible to sideload the OTA without unlocking the bootloader - but it's highly discouraged to try a Beta with a locked bootloader, as you'll be locked into the Beta program (via manual OTA sideloads) until it goes final, and you'll have no choice but to deal with the issues.
I don't plan on testing Betas of any sort, but feel free to use this thread for everything about the QPR Betas or major Android version betas for the Pixel 6 Pro. I'll update the information in the OP when necessary. See Post #1 in my main thread for general information (Unlocking Bootloader / Rooting / Updating | SafetyNet working again | ADB/Fastboot & Windows USB Drivers) but ask questions or make observations about all betas in this thread, please.
Once a QPR or major Android version goes final, I'll take those discussions to my main thread.
