Need help to downgrade firmware (wrong region)
2020-09-11 14:51:48
Model: Archer C7  
Hardware Version: V2
Firmware Version: 3.15.1 Build 160719 Rel.57530n

Need help to downgrade my firmware. Brother mistakenly updated firmware to (EU) version. My router says (KR) after the model number.

 

After update, the wifi broadcast stopped working, even after factory reset.
