My mother’s Redmi Note 2 is running a beta version of MIUI 7 (5.9.18) and I want to update it to the stable version. The instructions given in the FAQ are: back up your data either using the miui back up app or third party app such as titanium download miui rom for your device place this rom on your sd card reboot into recovery flash the miui rom wipe dalvik reboot your device as normal once the rom has successfully flashed If I follow these instructions will the apps, settings and files be saved after the update or will everything revert to a default installation? Also, the update app on the phone currently shows an update is available to 5.12.17. If I upgrade through the update app would that update to the official Xiaomi ROM rather than the Xiaomi.eu ROM? Thanks for any advice you can offer.
