Lumia 1020 WP 8.1 downgrade to WP 8.0
After upgrading to WP 8.1 Dev version, the battery of the phone is draining...100% battery can be only last 3 - 4 hours, this issue is still persisted no matter how many times i reset the phone. I then try to use the Nokia Recovery Tool or NSU to downgrade to WP8, but both application is not able to recognize my phone...it is RM875
Can anyone here help me???!!!!! Or, is there any other way to downgrade?
