#2. SETTING UP MIUI OTA (on supported devices):
1. Download the most up-to-date release of OrangeFox Recovery
2. Download a full MIUI ROM that will be the basis of your future MIUI experience, and copy it to your phone’s storage
3. Flash the OrangeFox Recovery zip with your current custom recovery (or follow the steps in the thread for installing from adb/fastboot)
4. Reboot into OrangeFox Recovery (this will have happened automatically if you flashed the OrangeFox zip)
5. Go to the OrangeFox settings, and enable these MIUI OTA settings -
a. Support MIUI incremental OTA
b. Include system in OTA survival
c. Incremental OTA signature verification
d. Aggressive stock recovery deactivation
e. Disable DM-Verity (note: do not enable this for the newest Xiaomi devices released in 2019, or when flashing the latest MIUI ROMs for Android 9.0 or 10.0)
7. Go to the “Wipe” menu, and wipe data, cache, and dalvik
8. Reboot OrangeFox
9. Flash your full MIUI ROM. After the ROM is flashed, OrangeFox will start the "OTA_BAK" process, which will backup your system and boot partitions into the /sdcard/Fox/OTA directory. You must NOT delete any of the files in the /sdcard/Fox/OTA directory. If you do, then incremental OTA updates will most definitely fail.
10. Reboot your phone, and start to use your phone normally
11. When MIUI notifies you that there is an update, download the update, using the MIUI updater app, and allow it to reboot automatically to OrangeFox
12. OrangeFox will install the update automatically (this might take several minutes)
13. OrangeFox will reboot the phone automatically upon completion of the installation of the MIUI OTA update
14. After this, you will not need to flash a full ROM any more - just follow the steps in #10 above
15. If you want to move to a completely different version/build of MIUI, then you will first need to clean-flash the full ROM of that MIUI build, as described above.
