Pixel 3a XL downgrade drom Q to Pie - Google Pixel 3a XL Questions & Answers

I want to downgrade from Q Beta to Pie.
But it states "fastboot to old".
Didn't find any help in the google universe.

Its obvious. Use a newer fastboot. Use the latest one there is that's offered by Google (prebuilt)

Yes, already have latest.

If that doesn't work you could always try just removing the fastboot version check from the script.

Deleting the check in the script has done the trick.

Flashfire doesn't fully support Oreo yet so that's a no go, same with TWRP. ADB sideload might work.
I just flashed it this morning and had no problems.
I flashed a couple of hours ago official OTA package via ADB. No problems till now.
I took the plunge and flashed the 8.0 stock factory image the done a factory reset after to make sure and it been great ever since turned off animation and it's nippy just wish battery was about better but I'll give it a few days see if that goes

Did you use Flashfire?
Does anyone know why the battery drains so fast on Oreo even after fresh clean install
Yes, Pro v0.60. I also maintained root and twrp. I had supersu 2.82-sr3 installed at the time so make sure you have that.

Well then, I guess it's just when coming from the beta that it doesn't work. Thanks for the heads up.

It is true that the OTA is out there. I confirm it because I signed-up to beta program to get the update and two days later I opted out to see if this is the latest official OTA ROM and I didn't get the update. So if you don't want to wait you can do the same it's safe. You can check the latest OTA here: https://developers.google.com/android/ota
The version is the same I have. 8.0.0 OPR6.170623.013.
I can confirm that jd1639's method works for people rooted with TWRP.
- download OTA (https://developers.google.com/android/ota)
- run Flashfire 60.0 (free version is OK)
- when asked "A system update has been detected", cancel
- Flash ZIP or OTA
- uncheck "restore boot and recovery images"
- press "EverRoot" and select "Inject SuperSU" and "Preserve recovery"
- Flash
- wait patiently
I tried flashing the modem FW using "Flash firmware package" on the OTA zip file. It rebooted and the screen went black for many minutes. I had to hard reset.
Can anyone confirm the 8.0 baseband? I have M8994F-2.6.39.3.03. I know that's the baseband for the 8.0 developer preview, but I wanted to make sure it was the final.

Probably a stupid question, but this OTA file- since it's ~1gb-, does it wipe the device like the full image?

No. There is no such problem.You can do it with any of the two ways if you didnt get the OTA until now. 1) Sign-up for the beta program install the update and then opt-out of it. 2) Flash the OTA files from Google to your phone. Or 3) But these are rumors and I can't be sure: An update will come at 11 of September with new Version of Oreo 8.0.1 with better support for Carriers (it is 8.0.0).

Cannot flash official 8.1 OTA over 8.1 DP2

I am on 8.1 DP2 which is OPP6.171019.012, tried to install the official 8.1 OTA which is OPM1.171019.011 : obviously the latter is older that DP2, so now I am still on DP2.
Maybe I need to wait for the OTA for those that are on beta program?
Yes, you'll either have to wait for the official OTA for beta users or use the factory images to my knowledge. You can use the factory images and just remove the wipe command ( -w ) from the flashall.bat file to keep your data

I can confirm this, I have updated this way.
anyone has the OTA for those on DP2?
Curiosity, how can the final version be older than a beta? I've seen this posted a few times now, how can/does this happen?
But after flashing the final, we're still enrolled to the beta. How to cancel the enroll without erase data ?

It isn't, but they probably put an unreasonable date stamp in on purpose to avoid any potential issues in the flashing process.

So those on DP2 with unlocked bootloader when/how will be able to update to official/final 8.1?
Usually an OTA is made to go from one specific build to another. Which would make sense on why you can't do it that way. If you have the unlocked bootloader flashing the factory image for 8.1 can be done.

If you have an unlocked bootloader, you can update now with the factory image. Otherwise wait until the OTA rolls or for beta users.

I just got the small ota to bump me from DP2 to final. So it's in the wild now. You can probably force the update at this point.
Like he said, I just got the official OTA bump yesterday to final. If you can't force it, it should come soon regardless.. This shows the December 5th patch.

Pixel 2 XL Verizon anyway to sideload Andoid P

is there anyway to Sideload Android P Preview on a lock Verizon Pixel 2 Xl ? I can get it to work getting errors like E:footer is wrong e:error 21 E:signatire verification failed
Thanks
https://developer.android.com/preview/download.html
Go to your recovery and flash it through adb sideload
I tried to flash it the ADB Sideload update.zip and it get to 0% and fails
You may have to enroll in Beta first in order for P to work.
There is no Beta Yet For Android P

After doing some research, you have to be bootloader unlocked to flash the Android P firmware.
This is a developer preview. Next version will be Beta and then there will be an ota method.
update your adb and fastboot.
and get the OTA from here: https://developer.android.com/preview/download-ota.html
Remember if you go P on Verizon you can't go back because of the locked bootloader.
Is this still accurate? To sideload the OTA preview , any downside other than the locked bootloader?

You can flash the factory images through adb to go back to 8.1. I was on P and went back

Yep, P is technically older than what you have so it won't OTA. A new P is due any day now.

Android 10 root/twrp

Hey guys. I accidentally (don't ask) installed the update for Android 10 from 9 stock and lost my twrp and root. Is there any way to at least get root back without having to reinstall everything?
More details will be needed to help. Bootloader unlocked? Guessing yes since you say you had twrp. Check the guide section for root instructions.
Yes I have it unlocked. I looked at the guide and it looks like I will have to reflash the stock rom which I'd like to avoid.

Since, twrp is not available yet for Android 10 (Q), I suggest one of the three following options:
1. If you have to re-flash the Pixel 3 XL Android 10 (Q) Factory image, do #4 'keep data' in this Guide.
2. If your Pixel 3XL has the latest Android 10 (Q) Factory image installed, just do #9 A. in this Guide to root.
3. If you are on a Custom ROM follow the OP Instructions in the Custom ROM thread to root.
Apparently I have the Sept update (QP1A.19711.020.C3) but I currently have no available updates. Am I good to just use your step 2?

Yes!
Why not do #1 update your Pixel 3 XL to the February Factory image (QQ1A.200205.002). You will not lose your data (need to reinstall anything). Then do #2 to root.
I guess I can do it that way. Thanks.
Edit: Do I need to use a custom kernel? I don't really require one. Also in magisk manager, theres no way to select the canary channel. All I see is stable, beta and custom.

Some people are reporting that issue. You can set the custom channel to canary/canary debug manually. Check the magisk thread.

Hey so I patched the image and flashed the file, I'm stuck on the screen with the google logo and progress bar. Also, does it matter that I used adb reboot fastboot to get to the fastboot menu? I noticed it said fastbootd which ive never seen before. It seemed easier to do it that way.
Edit: Ive decided to try flashing another rom.

For flashing boot.img you should reboot bootloader. Fastboot is a separate thing now for system files to be flashed. Boot, bootloader, and radio are flashed in bootloader, others in fastbootd.

It unrooted, and I used the .5 magisk patched.img above without any problems, but will use .6 when available.

Theres a thread about this, there isn't a currently known fix either.

Now you can upgrade back to 5.10 and reinstall magisk before booting up the update. Works real easy.

Don't make things complicated, update to 10.5.10, boot twrp, install magisk from the zip
^ Pardon my noobness, but does the Magisk version have to match the OxygenOS version, or can I simply use the latest Magisk version? Lots of chatter about getting the Magisk that matches.
