I'm not very familiar with the Android system, but I recently updated my phone from 5.0.1 to 5.1. Unfortunately, one of the games I play doesn't support 5.1 yet, so I would like to revert to 5.0.1. From what I've read online, the main way to do this seems to be to flash a ROM on your phone, which, as I understand, is similar to factory resetting your phone with an older factory image. The problem with this is that it seems it would also delete the game data.
Is there any way to revert back to version 5.0.1 without this process?View original question
