,Then download the rom that u want again if there is developer availableu2026.
,Just in case there are non eu can try to learn and port recovery and rom to ur device u2026.
If u can u2026.
,A price of advice jsut in case u didnt,Search in XDA threads probably u mi8 get something,Moreover samsung had a crappy OS previously but after one ji I think he stock rom in itself is good .
