Jesus .. you're one arrogant POS. No one is obligated to give you anything or any kind of help. Learn some proper manners and do some research before attempting to do operations on your device that will definitely brick it. I think flashing ROMs might be above your IQ level. Better get someone more intelligent to do it for you.Can you find it ? I dont see that newest 3.5 for Mi 10 Ultra is existing. So dont be so smart...
