Hi,

i need help to unlock a Redmi Note 3.
After making a factory reset the phone first ask me wait about 30 minutes. Then i have to enter a 4 digit code, which i dont know. If the code is wrong i get another try after 120 minutes.
Seems like something went wrong during the reset cause some data are left on the phone (whatsapp stuff)
TWRP is also gone which was installed by me the inoffical way. Looks like bootloader is locked again.
USB debug mode is deactivated. ADB does not list the devices.
Any idea how i can fix it or which code it might be?
