Hello everyone, I'm not sure if anyone has made a thread with this exact tutorial but today I'm hopefully going to teach you how to downgrade to android 10 without unlocking your bootloader.

1- download the recovery firmware with the exact same version you are currently running on your poco x3 nfc, and download the version you want to downgrade to and then move those two files to your poco x3 sd card or local storage... https://xiaomifirmwareupdater.com/archive/miui/surya/

2- go to settings/about phone/miui version and then press the miui logo a few times, this will unlock some extra features that we need.

3- press the 3 dots on the top right of the screen, and then choose update package, and select the recovery firmware of the version you're currently running, after it prompts you to install the package don't accept it nor cancel it, just go back to your home screen and enter the file manager of your phone, and rename the file which has the version of the firmware you want to install, to the same name of the file which has the version of the firmware you're currently running.

4- go back to the update page and accept the update prompt, it should now trick the device into installing android 10.

5- after it's finished it'll reboot into the stock recovery, from there you'll have to wipe data, and that's all.



I got my phone a few days ago and have to wait 7 days to unlock my bootloader, and on the newest miui update there seems to be an issue with gestures, they make the device really laggy for some reason, rolling back to android 10 was the only option for the time being, so I found this way to do it without unlocking my bootloader :)

You better stay locked in A10 !!!

Once you unlock the bootloader, your DRM will drop to L3.
I give you 1 million dollars if you stay in L1 (bootloader unlocked) after downgrade to A10 !!!

Congratulation :cool:
I guess you owe me 1 million dollars, I unlocked my poco x3 today and flashed Dot OS 5.2 android 11, and I got L1

I told you A10 ... not A11 : read again my comment !!!
Try now to install an android 10 custom rom or MIUI 12.0.8.0

LOL ... funny guy !

I updated to android 11 and downgraded to android 10 (and unlocked/relocked bootloader) so many times that i can't count (always done via fastboot with MiFlash), i currently am on A10 12.0.7 and still working everything fine with L1. You probably done something you shouldn't do if you had problems with widevine certification

You are now in A11 wich is compatible with your TrustedZone in your current firmware so you have L1 back again !
Do you understand what i wrote here ???
Have you read my guide too ???

I told you, flash an android 10 custom rom not A11 to see if you will keep L1 !!!

Then why you downgrade to A10 in OP then flash an A11 custom rom : that makes non sense !

That's not a custom rom and you have locked your bootloader !

Don't you read "CUSTOM ROM & BOOTLOADER UNLOCKED" !!!

Hi thank you for this guide
I'm just a little confused at step 3, do we rename the current recovery firmware to other name too and then proceed with renaming the downgraded version firmware to the same name of current recovery firmware?
sorry for bad explanation but I hope you get what I'm asking

    This will hard reset the device? How about the miui version still version 12.5 or lower?
