1. Return to factory stateI flash this forum ROMs few weeks ago its 3.8.16. How come I can't update in setting-about phone-system update? Update via WiFi..which is faster ..or I have to DL new ROMs rename update.zip do whole process again every time new patch? Sorry I'm kinda new here ..some give me answer thanks
2. If you are on vanilla, there will be no miuiandroid-OTA. You should put pre-downloaded 'aries.zip' in root folder of sd card and choose this package in Updater application (menu key - select install pack)
3. After miuiandroid-edition will be flashed you should do additional reboot
4. Now, return to factory state from Settings (miuiandroid-edition will remain intact)
5. Additional reboot
That's it, now you can just flash new 'aries.zip' every friday either through OTA+wifi or as described in point 2 - all you apps and data will remain untouched. Have a nice experience
