i have 3 questions, with short answers please
my MI5 has TWRP3.1 + root+ bootloader unlocked+ global developer rom 8.3
all ok perfect. with TWRP i did factory reset ( which contains data and chache wipe) to have everything clean.
But
i still have some old application folders, files, even my old media inside the phone!
how to clean them? i want to delete all files which is not about new system.
1) in TWRP;
advanced - wipe system
or
advanced - wipe internal storage?
which one?
2) and if i delete all, i want to reflash new rom
without quiting from TWRP,
, but new rom zip file will be deleted also i think ! so how can i reflash?
3)
i ve changed imei number of my phone , i hope my new imei number will not be deleted?
