You may have a problem with your motherboard as far as connection goes or with Bluetooth connection. You can try to look at this guide even though it is for a different drone. It still might help! Yuneec Breeze 4K Motherboard Replacement.
Now I may be wrong, but from what I have heard is that once you get the red ring of death I believe that it is game over. All my friends who have ran into this problem told me they had to get a new xbox. However, hopefully you can find a way to fix it instead of doing this!
I have an iphone however, I believe that for most phones you must plug it into your computer and do it that way. You will have to type in account info and then password and it should let you reset your password.
Try turning your wifi off and then your phone off. Turn the phone back on and then turn the wifi on. Also, you can try taking the sim card out of the phone and wiping it down. Take the sim card out with a paperclip. Hope this helps.
