mi note 10 pro (tucana), dirty flash:
1 - no access to media storage so: can't download or send media on social (whatsapp, instagram etc.), can't download apps, gallery and file manager crash everytime i open them, camera doesn't work, can't backup using apps or also mi cloud (for a clean install).
2 - Really laggy at startup, then it goes better;
3 - Battery drains omfg fast;
4 - twrp mtp doesn't work;
5 - can't root, if i try with magisk v21, reboot system and then FASTBOOT.
What can i do to improve without losing all my data?
