[Tuber]

I guys have such a problem, I now have a version of the system 18.0830.2101.86, And the update came to me The first of September 2020 and at the moment I have not come updates and now I want to update my phone to Android 13, but I don’t know how to do this, I tried to download the official file Updates to android 13 but it turned out so that the phone sees this updates, but when I click it updates, it flies out an error and I don't understand why help me please

The only way you can update is following the order: A11 > A12 > A13. One cannot jump from Android 11 to Android 13. The A13 update you downloaded won't upgrade if your version is A11 unless you have A12 then only it will work.
