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.

I've a device that is S-ON , TWRP 3.0.2-0 recovery installed , unlocked USA. Was running CM13 and later a lineage build...i just wiped/ reflashed the stock boot and system image so i've got things more or less back to original. All's good. However my bootloader remains unlocked. Do i need to relock it to get Android Pay working again? I was able to add a card, but have not tested it in the real world yet. My understanding is locking the bootloader will erase my data. Given I'd like to try that Nougat flavor and I don't think that will come OTA with an unlocked bootloader, maybe now's the time sense I think i'll have to flash that manually
Sorry, still new to joy of working with these devices. Fun tho

No, if Android pay has a problem, it will reject you DURING the process of adding a card, if you add a card sucussfully, your good to go.
If you want to try nougat, please note that that change is irreversible. The firmware is non-downgradeable. I don't think locking the bootloader will erase data, but if it does it PROBABLY will warn you.

Thanks for all that...just to be clear, the only way to get Nougat is to flash it ? or is it also OTA?

It is an OTA, you can have s-on, but you can't have an unlocked bootloader, root, or system modifications if any kind.

Sorry I have a question, I have an A9 (European model) S-ON with CM 14.1 and I would like to get S-OFF in order to back to stock. The problem is that I have read that Sunshine only works with stock ROM and, out of the box, my phone came with vodafone uk ROM and I can't find, on the internet, the exact same ROM as mine ( I have found an older version but because I have S-ON I can't downgrade ). There is another way to make Sunshine works? Thanks in advance

Good, I think you can download the ota and sideload it, should be in one of the general threads. Think it's called any news on 7.0
So, after all this, i had Android Pay (AP) working great w/ 1.57.617.60 flashed back to my phone. I never re-locked my bootloader. This a.m. i flashed nougat, both boot and system (RUU_HIA_AERO_UL_N70_SENSE80GP_ATT_MR_NA_Gen_Unlock_2.18.617.1) - All's great. However while shopping i was rejected by AP with the message in the attached screen shot. Is this because i never re-locked the bootloader? What are the consequences by doing so? Can I eventually re-unlock for future flashing?
NOTE - my device is not rooted, despite the accusations from the modal!

In nougat, it checks for unlocked bootloaders sadly you can't relock bootloader in nougat.

My goal was keep su and also get nougat. A9 has the bug about OEM unlocking just like all other 7.0 devices. It will most likely get fixed at 7.1.1, the nexuses and all other devices running 7.0 seem to have this "bug"

ahh, so that means, as i understand it, if all goes to plan, we should one day expect a 7.1.1 update that will allow me to finally get back to AP?

As long as you don't care about root. You can always downgrade to mm, lock, and OTA back to nougat

No, you can only UNLOCK in nougat. If you want to relock the bootloader, you will have to downgrade to marshmallow and loose your root, or wait for Android 7.1.1
downgrade means i have to wipe data, right? The upgrade that was not the case. I am only assuming
I've looked all through the forums and haven't found a clear tutorial on how to do this, if it can even be done.
I have a Verizon bought, bootloader unlocked, Magisk rooted Pixel 2 with TWRP and a custom kernel (Flash 2.06) installed running 8.1.0 with the December security patch.
How would I go about updating to future monthly patches (e.g. January's)?
I'd prefer to not lose all data (i.e. OTA-like), but am willing to start clean. Definitely do not want to risk losing the unlocked bootloader.
Is it possible? Willing to try if there is a semi-reasonable assurance of success.
Thanks.
If you're familiar with fastboot you can pull out the image.zip from the factory image and fastboot it with the command
Code:
fastboot update whateverthelongassimagename.zip
Leaving out the -w in that command won't wipe anything. If not, you'll have to get the stock boot image and take the OTA. Either way you'll have to temp flash TWRP again, installer to keep it there and your kernel and Magisk.
When we get an update that requires a new bootloader, that will have to be via OTA or adb sideload. VZW seems to have blocked us from fastbooting that.

I'm guessing on Verizon you wouldn't want to update the bootloader anyways since that would likely fix the current method of unlocking those phones.

They most likely will patch the unlock yes, but they're not going to send an update that will relock the bootloaders that have been unlocked. So I wouldn't see an issue with updating it. Unless for some reason you need to lock it back. The bootloader in this months security update is still the same as last months. Version number is the same.
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.

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.

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.
So I first bought my Samsung a11 as an android 10 model,
I then flashed it after I bought it with an open-line android 11 version and got twrp and root. This was a year ago I think.
Now they released the final update for this Samsung phone model, and I want to at least get the latest and last version of my phone.
But I kinda forgot how to do the procedures again.
So my question is does flashing the new android version firmware using odin remove TWRP installed on my device?
my phone model is: A115FXXU2BUJ2 (android 11)
the firmware I want to install: A115FXXU3CV13 (android 12)
if so what do I need to do in order to successfully have both the new firmware I want to install and twrp installed on my device? (i kinda know how to root using twrp and magisk so no problems here)
Any help would be much appreciated!

Yes, flashing the update via Odin will remove TWRP and root, it will also, more than likely, lock your bootloader, then you won't be able to reinstall TWRP or root the device unless you unlock the bootloader, if it can be unlocked.

If the bootloader in the update is a securely locked bootloader, it will probably have locked bootloader after flashing and might not be able to be unlocked. That was the whole point of me warning you in my last post. Now I've had to post again just to say the same thing that I already said. I guess I was talking to the wind.
There is no way to know what the results will be after updating unless you find someone that has already updated the exact same model number of A11 or bite the bullet and update yours then see what you get.

I see, looks like i need to find someone who have done it and see if it works. I didnt get what you mean about after flashing, it might have a chance to lock the bootloader depends on the update. I think ill just try and see what happens. Thank you.
I dont know guys with that phone but there should be a tool that bypass auth and unlock the bootloader in any case. I ONLY knows MTK devices, not sure about that samsung i use a .Bat file.

No, I said that after the update, it could cause the bootloader to be locked and then may not be unlockable from that point on. It depends on the bootloader in the update. If this happens, you will be unable to install TWRP or root via Magisk. That is why you need to confirm whether or not flashing the update will relock the bootloader during the flashing process and, if it does, whether or not it can be unlocked again after the update.
In other words, look at exactly what you are about to jump into before you make the jump because you might land in the one place that you absolutely do not want to land.
