Attention: My builds of lineageos are signed with my keys. To migrate to it without format data you have to flash this small zip to "prepare" for my keys: https://sourceforge.net/projects/eph...d.zip/download
1. Reboot to TWRP. *
2. Wipe cache, dalvik cache, data and system.
3. Install 8.4.19 or 220.127.116.11 stable firmware. **
4. Install ROM.
5. Install 9.0 Gapps for ARM64. ***
* this twrp is recommended: https://forum.xda-developers.com/mi-...gefox-t3871583
** you only need to flash this once
* You tell me.
