Hello. Yes, we rechecked, this happens because you try 9.78 and then 9.79 version of lg tool. 10 credits refunded. Can you try other pc? This is driver issue, do you installed the latest drivers? Also sometimes problem can be in slow pc, so you can also try to use another pc. Also you can try this: after reboot disconnect phone, wait until it boot to download and then connect phone to pc.
