i think its possible if you can find Android 11 rom in anotjer websites or you can try to find a device that is not upgraded and then took rom backup from that and then use it in your device but i think you need to unlock bootloader in all cases
[Moto G40 / G60] arsradu:
The ROM is not a problem. I already have a backup from before the update. Also, there are third party mirror sites for that. So that's not a problem. :)

The only thing I was curious about is whether or not it would be (theoretically) possible to downgrade an Android version (in this case, let's say it's 12 down to 11) without unlocking the bootloader.

I guess the answer is no then...

If I had another Moto G60, I'd try this myself. But I only have one... So I can't really test.

I was hoping someone already tried before. Or at least knows the theory around it.

Thank you very much for your reply! :)
[Moto G40 / G60] arsradu:
Yeah... Thing is, you can unlock and relock the bootloader. Also, is it the same phone (same IMEI) with the one you sent for repair? Cause they sometimes just replace the phone entirely.

If they really downgraded your OS, it would be interesting to know how they did it. Simple reflash of the OS? Or unlocked bootloader, flashed and then relocked? Cause that will work for sure. :))

Now, there's also another thing. That was a Realme, this is a Motorola. Different manufacturers might have different ways/tools to achieve the same thing.

But the idea remains, of course. It should be possible to downgrade the OS, if you bring your phone to a repair center. However, what I'm trying to understand here is if you can do it yourself, at home, with a simple data cable and the OS itself, ooor...if you need special tools for that.

Also the question is hypothetical. I don't plan on actually bringing the phone to a repair service for downgrade. I just wanna know if it's possible, so I can eventually do it myself at home. :D Sending the phone for repair to a repair center usually takes time. So...if it's not a hardware issue, I'm trying to fix it at home. :)
[Moto G40 / G60] ankurpandeyvns:
Dude, I relocked my bootloader and guess what, now I cannot do anything.

Booting into the OS is not working as it says no OS found

Flashing images does not work since the bootloader is locked.
[Moto G40 / G60] arsradu:
Do you also happen to have an answer to the question in this topic?
[Moto G40 / G60] KayaNN:
SAME issue with mine - we have all talked about this in the other posts. Unlocking bootloader on Moto phones seem to be risky. ONCE UNLOCKED, I SUGGEST PEOPLE DO NOT RE-LOCK THE BOOTLOADER AGAIN ON ANY ANDROID PHONE FOR THAT MATTER !!
[Moto G40 / G60] KayaNN:
I have searched everywhere on the net and there's no solution to rollback an android 12 to 11 (i.e. without unlocking OEM)

Just curious - my G60 is on android 11 right now and I'm really hesitating in updating it to 12.

Why are you and other people talking about a rollback? Is the performance/bugs on 12 that bad?!! o_O
[Moto G40 / G60] arsradu:
No it's not. But Android 12 comes with a few design choices not many people would like. So...I would suggest searching online for a review of the Android 12 update (there are plenty of them on YouTube for example) and see you're ok with those changes.
[Moto G40 / G60] KayaNN:
I did check them out and the negative reviews were aplenty. I wanted a few reviews from the XDA community on Motog60 having Android12.

Which design choice did you find cumbersome/unwieldy?
[Moto G40 / G60] arsradu:
For example the quicksettings toggles. They are bigger in Android 12, they take more space, and in terms of connectivity toggle, Google combined Mobile Data and WiFi, which...I personally would have preferred them to be separated (like in Android 11 and previous ones), but...it is what it is. It's not that bad.

Also, something else you might like or dislike, is the new Material You design. Which takes colors from your wallpaper. In my opinion, it doesn't work very well. I mean, it tends to give you very little contrast between the icons and backgrounds. It's not that bad, you can customise it...to a certain extent, but...it's a design choice I wish Google would have thought more about. It looks like something that still needed more time to mature. It looks a bit rushed and unpolished. But you can get it to look decent.

And one more thing, and I have no idea why they did that, they removed the ability to customise fonts and icon shapes.

Motorola still kept them in their version of Android 12, but it's been removed by Google from AOSP.

If you watched those reviews and you're ok with those changes, just go for it.
[Moto G40 / G60] KayaNN:
Thanks for elaborating dude (y) It makes sense now - I thought those very same customizable features were a bomb. Now after understanding your point to view, I'd rather stay in 11 😄

Cheers!

And also, good luck in rolling back to 11 without unlocking the bootloader. Keep us updated when you do find a way to do so!
[Moto G40 / G60] zankdroid:
Hi,

I have a Moto One action XT2013-2 RETIN running on Android 11 July 2022 security update. I want to downgrade it to Android 10. After 11, the HDR function of the camera and NFC stopped working. Can I safely downgrade it to Android 10 without unlocking the bootloader ?.

Do you still have the One Action with you? If so, I kindly request you to confirm whether it is safe to do so with One Action.

Also one more question, can i fix the NFC and camera HDR issue without downgrading to Android 10 ?. I had a look into the dtbo file, opened in Notepad and found out some chip level instructions and found something regarding camera HDR and NFC. Is there a safe way to modify the file to get back HDR and NFC

working?
[Moto G40 / G60] arsradu:
No, I don't think you can downgrade to Android 10 without unlocking the bootloader. I'm trying to confirm that myself. But so far, no, I don't recommend it. You can try if you want, but most likely, it's not gonna work.

I don't know what the issue with NFC and HDR is, but I would recommend trying to figure that out instead of thinking about downgrading. I don't think the issue is the update to Android 11. I think the issue is somewhere else (possible hardware).
[Moto G40 / G60] zankdroid:
I have seen another guy on Lenovo forums with the same issue. His phone was a RETGB version. He says the Android 11 September 2021 patch caused the HDR issue. The problem is same as mine.

If I try to downgrade to 10 , will it result in a hard brick which even the Rescue software wouldn't be able to save ? like a permanent brick?

I have gone through the dtbo file and searched for NFC and HDR. Found some differences here

Android 9

sec-nfc, ldo_en exynos,block-type exynos

Android 11

sec-nfc,ldo_en sec-nfc,pmic-ldo exynos

I have found some lines in the dtbo file like

HDR Max Luma, Average Luma and Min luma etc which represents the three exposure images that the camera captures to produce an HDR image

Android 10 dtbo also has some differences compared to 11

Is there any way to port the old camera software to Android 11 and also to fix the NFC issue?

Can I replace the Android 11 dtbo file with Android 10 dtbo and then reflash Android 11?
[Moto G40 / G60] arsradu:
"If I try to downgrade to 10 , will it result in a hard brick which even the Rescue software wouldn't be able to save ? like a permanent brick?"

Never tried, so I don't know. If you do it with an UNLOCKED bootloader, it should be fine. I don't know about locking the bootloader after that.

But what I would recommend, if you want to attempt this, is boot into Android 10 (after flashing), BEFORE locking the bootloader, and make sure the OEM Unlocking option is still ON (meaning bootloader is still unlockable)! Yes, even if the bootloader is currently unlocked. That option is very important.

If it's still ON, THEORETICALLY you should be able to lock the bootloader back. And, even if there would be issues, since the bootloader is still unlockABLE, you should be able to fix them by unlocking the bootloader and flashing whatever it needs to be flashed to fix this. I repet, this is only a THEORY. Attempt this on your own risk!

My Moto Action is on July security patch right now (RETEU). So...I can't confirm anything regarding September security patch.

"Android 10 dtbo also has some differences compared to 11

Is there any way to port the old camera software to Android 11 and also to fix the NFC issue?"

Never tried it. It should be possible. But also, I have a feeling the camera software is actually the same. So, if it's a bug with the camera, it should be present in both. But I don't think the camera is the problem here. I think the actual OS is the problem.

Are you using the correct build for your region? Have you ever flashed something else? This is weird, for a stock ROM.

"Can I replace the Android 11 dtbo file with Android 10 dtbo and then reflash Android 11?"

You can try... I never tried it, so I don't know if it works or not.

HOWEVER, all these things seem like a very complicated way to fix these issues, in my opinion.

IF the problem is hardware (NFC for example, which I still don't know what's wrong with it), you need to fix it on a hardware level. If it's software, you need to submit a bug report to Motorola, so they can fix it in an update.

If the HDR thing is a software issue, and it's been intriduced by an update, you need to let Motorola know about it, submit a bug report (with logs) so they can fix it with a future update!

What I'm trying to say is that downgrading is NOT the way to go!

It's not easy. It will break your warranty (if you have any), because you will likely need to unlock the bootloader, in order to downgrade, and if it's a hardware issue, it will not fix it.
[Moto G40 / G60] zankdroid:
Is your

I am from India . When I bought the phone and booted it for the first time, the default language was English United States. NFC and HDR were working fine, Auto HDR very well responded to changing light conditions and produced well optimized HDR images.

Got Android 10 after a few months and even after that everything was fine.

Following one Android 10 security update (can't remember which update), the file manager started crashing.

Then for the first time I tried a Rescue using the official Lenovo rescue Software for a clean software installation. The software detected my phone and downloaded the correct firmware and installed it.

After rescue when the phone booted up to the setup screen, the default language was English India.

The File manager crashing issue was fixed. NFC and HDR continued to work fine. Everything was perfect until I received Android 11. After that NFC stopped working.

Auto HDR is now not detecting ambient light conditions very well and with HDR ON mode it is not optimizing the bright and dark areas of the image.

As I have told earlier, In Lenovo forums I found another guy who is having RETGB version of One Action with the same HDR issue. He didn't mention anything about NFC. I have also contacted Lenovo regarding the issue but of no use.

Is NFC and Camera HDR working well in your phone with RETEU firmware?.

If it's working can I install RETEU firmware in my phone?. I don't know about the carrier frequencies in Europe and India.

I am currently on July 2022 RETIN

RSBS31.Q1-48-36-26 version and I believe July security patch is the last update for the phone.
[Moto G40 / G60] Marko Indaco:
The problem is the firmware. You must check for the right firmware version for that Android release.

Let's say for example: I flash a custom rom A10 based and I take a nandroid backup with TWRP. Then some time later I flash the upgrade for this custom rom to A11 (flashing the correct firmware for this release) and I take a nandroid backup also for this rom upgrade. Now I have 2 nandroid backup, one is old A10 and other is for the new A11. Well, if I try to RESTORE the old A10 based rom, it don't works, because I previously flash the firmware to flash A11 rom.
[Moto G40 / G60] arsradu:
Exactly. But does it have anything to do with the security patch level, or is it just in my mind?

Meaning, should it be possible to downgrade, as long as both Android 10 and 11 in your example, have the same security patch?

Cause I've noticed something. Every time Motorola releases a new Android update, they stop any security patch for a couple of months. Then they release the new Android version, which has the same security patch as the old version you had.

Is it just me, or is this done on purpose, so you can easily downgrade, in case you want to go back? Cause if they would offer you security patches, you wouldn't be able to install the new Android version, cause you would have an older security patch level. So it would be like upgrading the Android version, but downgrading the security patch level. And I don't think you can do that. At least not without unlocking the bootloader. But if you do unlock your bootloader, you can go back to whatever security patch you want. It wouldn't matter anymore.

Has anyone tried to confirm this theory?
[Moto G40 / G60] arsradu:
Well, once again, I'm not sure what your issue with NFC is. But...yeah, my NFC is working fine. Same for HDR.

Have you considered factory resetting the phone and not restoring the backup (clean installation)?

My build number is RSBS31.Q1-48-36-23-2. If both are at July security patch, technically, you could just flash the RETEU one.... Technically. I just want to say I've never done that. So, IF you really want to try this...proceed with caution.

Also, yeah, most likely you won't have services like VoLTE/VoWIFI for IN carriers, cause...well, it's not for India. Also, the signal level might be a bit worse. That's usually the case with ROMs made for other regions.

However, in my opinion, you should check to see if your problem is not hardware, by any chance. Cause if it is, any software you would install, won't make a difference.

If you say the HDR function needs the light sensor to work, then try to test that. Same for NFC.

What I'm trying to say is just test your hardware first.

You can use an app like this, for example.

Only after that, you can think about changing ROMs, flashing ROMs from other region, downgrading and so on so forth.

I have a feeling this is probably not a software issue. So, even if you did downgrade or change ROMs and so on so forth, it wouldn't make a difference, because the issue is not software, it's hardware.

Anyway, that would be my suggestion.
[Moto G40 / G60] Marko Indaco:
For what I know no but, could also be that for stock roms, maybe, there's a way. I never used stock roms since I use Android phones. I usually unlock bootloader+flash some custom rom the same day (or few days later) I buy a new phone.

Let's see if any have a more comprehensive answer 👓
[Moto G40 / G60] zankdroid:
Can a firmware update or security patch damage a hardware?. I have heard incidents of Xiaomi Poco X3 Pro dead camera and mainboard failures following updates.

As my problem occured after Android 11 update, I suspect so. Also about that guy I mentioned in the Lenovo forum with RETGB firmware also had the same issue. The device received Android 11 on August 2022. That guy says the pictures taken after September 2021 update showed HDR issues. He didn't mention anything about NFC.

I have tried the app you suggested. In that app I tried NFC check, bought an NFC debit card behind the phone and nothing happened. I used to transfer files using NFC with this phone successfully with other phones previously and used to make a notification sound while tapping debit cards. Now it's like dead. I can turn on NFC in the settings and the icon appears. But that's it.

Is there any way to know the NFC chip type?. I have tried some apps but none of them had options to show NFC hardware.
[Moto G40 / G60] arsradu:
Software can damage hardware, indeed. But I've never heard of a software update (especially an official one), and even less so a security patch, to do that.

However, what I noticed is that the app I mentioned above doesn't seem to work for NFC. Can you please, try the NFC Tools app instead?

Also, if you can, test with a known good tag. Either a known good card, or another phone. I tried both, and it works. But...only with the NFC Tools app. With the other app, nothing happens, as you mentioned.

As for hardware info, there are plenty of apps on the Play Store, for that. But I can't tell you one that would work for this specific case, off the top of my head. The ones I tested also don't have specific info about NFC. So...maybe it's called something else, or...missing. I'll have to try and test for myself first.

By the way, the NFC tag seems to be located under the battery, for as far as I can see. If you have a case on your phone, try to remove it for this test (in case there might be something that could interfere with NFC).

By the way, do you have a locked bootloader?
[Moto G40 / G60] zankdroid:
I forgot to mention one thing. After Android 11 for some period of time when I tap a Moto G30 and an LG Stylus phone to my device the G30 and LG phones displayed a message 'Tag not supported' or something like that. It was only for a short period of time. After that no response.

Before that both phones worked perfectly fine with my phone.

I have already tested NFC tools and nothing happened. I have also tested an app 'Test nfc'.

The app says the phone supports Android beam, Host card Emulation and Mifare Classic.

I have no idea what happened after Android 11.

I can see many people complaining about NFC in Moto One Vision and other Moto phones.

Have you tested your phone with Google Pay or any other payment apps?

The NFC service app shows version 11 and the Moto G30 phone that runs Android 12 shows NFC service 12. Is there a way to replace it to version 10?.

The bootloader of my device is locked. I have downloaded RETEU and the global XT2013-2

RSBS31.Q1-48-36-26 versions from lolinet and going to flash and test both .

By the way I read your firmware version as RSBS31.Q1-48-36-23-2. Mine is

RSBS31.Q1-48-36-26.
[Moto G40 / G60] arsradu:
I haven't tested NFC Payments recently, since I no longer use the One Action as my daily driver. But...I see no reason why it wouldn't work. The tags are detected, so...it should work.

The reason why I asked you about the bootloader (locked or unlocked) is because, apparently, with an unlocked bootloader, you can't use NFC Payments anymore. The actual hardware should still work. But you can't use it with Google Pay (now called Wallet) for NFC payments.

Your RSBS31.Q1-48-36-26 is also on July security patch? Usually, IN builds are usually receiving the updates earlier than the rest of the world.
[Moto G40 / G60] zankdroid:
To my surprise, today I found an old One Plus One phone in a shelf which belonged to a relative who left it in my house. The NFC of my phone is perfectly working with that phone!. I successfully transferred some files. That phone responds to my debit card and everything is fine.

Then I tried Moto G30 running Android 12 with that One Plus. But this time no response.

I have read that there was a security bug in Android NFC and Google fixed it. I think the bug is related to Android beam.

The phones I have seen that came with Android 11 out of the box didn't have Android Beam feature.

My phone which is released in Pie have Android beam and it's still there even after 11. So I believe some security patch in Android 11 is preventing my phone from accessing NFC with newer phones.

I have turned off Android beam on my phone and still it is not responding to any other devices except the One Plus One.

In simple words NO

It is like eating food without opening your mouth or digesting food without digestive system
[Moto G40 / G60] arsradu:
I see. So wouldn't you say it becomes a problem only when it's a downgrade? Cause if it's an upgrade, we have no "digestive" problems. :) You can upgrade without unlocking the bootloader.

So...why would you say it shouldn't be possible to downgrade just as easily? Also, have you tried it? Cause...the question was theoretical. And also, my curiosity if anyone actually tried it. My guess is your answer only refers to the first part.

I have a few questions for you.

First, is this Windows software, such as for a virtual machine?

Second, where is your kernel source?

Your timely response is appreciated.

XDA Staff

They ask me these questions , I as A college student try to answer it as best I found, windows based software, it's like a virtuàl machine , I think it's sort of more native app but I am not sure runs on windows 11 and works to bring Android 12.1 to windows 11 in Microsoft store you can only run Kindle app and Kindle app store but as above project is for allows more real Android software to work, that's the point of it, since it runs on top of windows , I don't know if there's any kernel source . I don't think it has a kernel but I could be wrong, anyway I wanted to post a direct reply here to if any other home users had questions, I hope I explain it better, I am running it for ebook reads Android based for my own personal desktop and for the Android games that can be played on windows, but I also use custom stuff from here on my Samsung Galaxy tab but I just wanted to share what I found with others if they didn't know about that project which I think is really cool that someone created that for windows 11. From my understanding of the windows subsystem for Android is I read somewhere online that it using an Android 12.1 version , the above project says something to that from what I remember seeing somewhere about it.
