I am currently on Android O D P3, unlocked bootloader, and rooted. Could I unroot and lock the bootloader and stay on Android O or do I need to flash the latest factory image and then upgrade to Android O through the beta program?
Thanks

If you want to get any OTA updates for new versions of Android O you'll need to be in the Beta Program. If you manually flashed the image for DP3 then you won't get DP4. Now, when the OTA update for public Release of 8.0 comes out I don't know if you'll get that or not.
If I were you I'd join the Beta Program without locking the bootloader so you can get the DP 4 and final Release. Leaving the bootloader unlocked just in case something goes wrong and you have to flash an image. Then, once the public release of Android 8 gets installed leave the beta program. That will keep you on the public releases without needing to do a factory reset.

What are your overall intentions? You can factory reset, which will unroot the device and then lock the bootloader if you wish. Leave the OEM switch enabled in case. There might be an OTA which will make it release version but we don't know that yet. Once again, what are you trying to accomplish?
Wait for official system image of DP4 and flash manually system&vendor images in fastboot

I was running cm12 on my nexus 5 and I had unlocked the boot loader and was asking xposed framework aplha version .
But then I decided to go back to stock android and I flashed the flashed the factory image of android 5.1 build number lmy47I . I wiped the data and even relocked the boot loader and now my phone is running smoothly and is on stock android.
But is there a way by which I can check if I flashed it correctly or not?
I mean nothing is broken but I heard android 5.1.1 update is around the corner so I was worried will I be able to apply the ota
Huh what? If it booted and is running smoothly its fine. If you didnt mod anything you'll get the ota

If you've flashed the factory image and everything is stock you should be fine for the OTA!
Thanks for the help
Lol....
You didn't need to relock the bootloader though. I tend to not ever want to relock it after unlocking it since that's about he only way you could potentially brick the device I think (Like if you relocked the bootloader and then for some reason the phone would not boot or something I am not sure how you'd unlock the bootloader again but whatever)

So I have a few questions about the android P beta program. I was wondering if anyone could answer before I opt into it
1) if I opt into I get ota updates which won't be Verizon variants so would I be able to jump back to Oreo?
2)would this allow me to unlock my bootloader possibly?
1) You should be able to go back to oreo by opting out of the beta and taking the subsequent ota from Google. Or you can manually flash a newer ota you downloaded from your computer. Must be a newer build than the the one you are on.
2) Almost certainly not. Unless there is some error, your bootloader will not be unlockable. You are not currently receiving "Verizon" builds. No such thing. Your device info is on a server side whitelist / blacklist. It has nothing to do with the build you have installed. That is my understanding.

Im not sure i understood this properly, I've already unlocked the bootloader of my Verizon pixel 2 on 8.1, if I update to P, will the bootloader be locked back? Or I can update and still enjoy the unlocked bootloader?
Thanks!

If you unlocked the bootloader already, it will stay unlocked until you lock it via fastboot from your computer. Flashing firmware will not relock it. Don't worry, updating to Android p won't mess with that.
I'm really enjoying this beta so far. The new navigation gestures are cool. Nothing so far that makes me want to go back to 8.1.

What version of magisk are you flashing? You should be using the beta magisk. Looks like people are having some success rooting with version 16.4.

That's correct. Just checking. You need to boot to twrp to flash magisk. There isn't another way that I know of. Maybe download twrp img again? I doubt its a corrupt download since you get the twrp splash screen, but its worth a try.

should i try to flash again the factory image?
or maybe opt out from androind p beta, install back oreo, root and flash android p without deleting my data?

You can boot into the OS right? Are you're platform tools the latest version?
Reverting back to oreo, rooting, and updating to p beta will either fail or wipe out root. You won't end up with p beta and root. Don't do that.

How to rollback from official 9.0 to 8.1 please help me
Yeah not digging 9.0
http://oxygenos.oneplus.net.s3.amazonaws.com/OnePlus6Oxygen_22_OTA_007_all_1805131952_O_MR1.zip
See if you can flash this from settings. It used to allow you to downgrade from Pie Beta. I'm not sure if it will work for Pie Official. You will most likely lose your data if you successfully flash this. So backup your stuff even before attempting this.
Or you can use the unbrick method to completely reflash your phone to 5.1.5 using MsmDownload Tool.

Download the 5.1.11 fastboot rom. Extract it. Open the folder you extracted and run flash-all-partitions-fastboot.bat
You see some things that look like errors but they aren't!! You have to have patients and just wait!!! When it completed it will say press any key. Then unplug phone and boot. You'll be on latest 8.1
Here's the link.

Hello
I also want to go back to android 8.1
In the phone settings in the local upgrade section, the old version is still available but the message "to avoid the failure of the start-up phase, no downgrading is allowed", is there a solution for to work around this problem?
Thank you all

If you're unlocked, flash it trough TWRP and format your storage.
If you're not, on a Sticky thread somewhere on this forum, you can get a rollback build (it's an Oreo build, the latest if i remember correctly, it's clearly called "rollback")
Edit : it's on this page : https://forum.xda-developers.com/oneplus-6/how-to/oneplus-6-mirrors-official-oxygen-os-t3792244
What issues are you all having with 9? I was on the BETA build when I first got the phone and had several issues.. but after downgrading to the recent stable build.. I haven't really had any issues..
Hi,
My Pixel 3a as an unlocked bootloader and is rooted.
Usually, when I update my system every month, I get the OTA update zip on google website to do the update and only patches the boot.img from the factory image with magisk to keep the root.
But this month, we get Android 12 and I saw on this thread : https://www.xda-developers.com/how-to-install-android-12/ that it was recommended not to use the OTA update for updating to Android 12 on unlocked bootloader.
As I don't know why, can you explain me if it is or not dangerous or impossible, and eventually why I have to use the factory image to install this new system ?
I know that every time i made a wipe data (even if i know there's a way to delete the -w in the bat file but it's not recommended) it made me a day to restore all my apps and configurations... So if i can avoid this, I'd prefer.
Thanks in advance

I don't see this warning on that page?
The point of the full OTA sideload is that works with both locked and unlocked bootloaders.
The factory image only works with unlocked bootloaders.
I have a 4a with unlocked bootloader and just upgraded using the OTA and it was fine. I normally use the factory image (removing the -w arg) but found warnings on the internet that this would break when upgrading to Android 12 so I did the OTA instead.
I was even able to re-root with Magisk 23 as normal, which is apparently not possible for newer devices (eg. Pixel 5 guide: https://forum.xda-developers.com/t/guide-update-to-and-re-root-android-12.4345627/).

About this question, it's written for OTA Updates :
"To install the stable build, you need to sideload the appropriate OTA package for your device from Recovery through ADB. This method will also work for Google Pixel devices with a locked bootloader"(but as I re-read it, I see that it's written that it "also work" with locked bootloader"). For the full update, it's written "If you have an unlocked bootloader on a Google Pixel device, you need to flash the full factory image of the Android 12 via Fastboot"...so I thought it was the only option.
But you're right, it's not exactly what's written.
Hello.
I have a bootloader locked Pixel 7 Pro with the April 2023 stock build.
I would like to downgrade to the October or November 2022 build.
Is there any way I can accomplish this?.
Thank you.
EDIT: Got an OTA build, but recovery is saying downgrades are not allowed.
Any other way?
Unless you unlock the bootloader, you cannot downgrade using an OTA. How you tried to flash the full firmware? Why are you trying to downgrade to a firmware that far behind anyways?

Reason, because on Pixel 7 and 7 Pro, firmwares from October and November, deleting an app, you can carrier unlock them, so I am trying to do that. I did it already with a 7 Pro which had the October firmware, obviously, if there is a reset on the phone, it gets locked again, but at least it's something.
I tried using the flashme.bat script, PixelFlasher, used OTA and Full firmwares, Fastboot and Recovery, nothing.
You cannot downgrade to a lower security patch without wiping data. Unlocked bootloader has the same behaviour.
