I have an issue with my newly bought UE Boom 2. Yesterday I could connect my phone to it with no problem. Today I tried again and it will show up:
Pairing failed. Incorrect PIN or passkey, please try again.
It should be a problem with my Meizu MX4, since I can connect my laptop to the speaker. I also did a factory reset on the speakers. But it still doesn’t work.
I have an idea, that maybe some wrong settings are saved in the Bluetooth config file. But problem is, I can’t find the file. It is not in /data/misc/Bluedroid. And nothing could be found with the ES Explorer search function, too. I also deleted Cache of Bluetooth.apk and BluetoothShare.apk. But all this didn’t worked at all.
Does anyone know a fix for this problem or knows where the Bluetooth config file is located or how to reset Bluetooth settings?
Thanks a lot.
