Downgrade to Android 10 with one ui 2.5 in A50

[AthulBhasi]

I cant downgrade from Android 11 one ui 3.1 to Android 10  one ui 2.5.

It shows like this👇

*SW REV. CHECK FAIL (BOOTLOADER) Pit flash binary unsupported version.*

It's security policy bro...unable to downgrade

[AthulBhasi]

So we will never be able to downgrade???

Well my dear we can always go up but never down. In mobile it's not computers which we can just flush out the previous os and then re install a new os. Here we can climb but we can't come down.

I saw videos downgrading A50 to android 10 one ui 2.5 without any issues.

[ARJUNB]

Well, not worth it. Trust me. No warranty, no future updates, 😢
Also on Google play store too. As things are going forward and u want to take a reverse gear. Why? May I ask. That you are so adamin to go back. Here people are shouting for android 12 infact we all are asking about it. And u wish to go back. What happened

Without root its never possible then how you can ?

[Catz420billa]

Even with root also it's not possible now because the bootloader version of your device is changed and now it can't be revert back to previous versions

[Vicky_A52]

You will never downgrade not possible with new security policy

Binary unsupported version error comes when you try to flash a firmware with an older binary number (or bootloader version) in a system in which a newer binary numbered firmware (with newer bootloader version) is already installed.

Simply put, you cannot downgrade once the bootloader has been updated.
