X220s no possible to bind

Hi. I just bought new drone second hand and was working ok. After when i restore to factory settings i lost connection with drone between my controller and drone. i dont know how to bind again . i try some tricks from youtube. but still cant connect it. i downloaded betaflight but not sure if i have correct settings there and on my controller. is anybody can help me here please?
Btw i have controller Flysky FS-i6

When your re flashed your FC you wiped all the configuration include the settings for the Rx
