friends, help unlock a redmi 9a dandelion, I do the procedure using unlocktool in the mtk option to unlock the boot loader, it completes successfully, but when the cell phone restarts the padlock does not appear open, if I also do the procedure to remove the mi account, it It also does so but then the system is destroyed, so I have to install the rom using the mi flash tool. Can anyone explain why even though it says it unlocked the bootloader, it doesn't unlock? Can anyone help me remove this account and unlock it?
