"Note 3 imei certificate fail"に関する回答Buy a chimeratool 3 day license. Activate usb debugging under developer options(tap buld number about 7 times). root the phone and after that do imei repair with the original imei under the battery. other alternative is to make a new falsh with odin. you can get the firmware from sammobile . this method will delete all your information so make sure you do a backup first.
