Paired with HTC one on 4.3 GPe
Using another method i came across i was able to pair with HTC one, answer calls and use watch styler
1. Install Galaxy Gear APK manually
2. When Galaxy Gear App opens it tries to install 0/19 files it will restart and say 0/18
3. When it says 0/18, locate "GEAR" folder on SDCARD, inside it will create another APK. Manually install this apk.
4. Close Gear App and Repeat Process, i got all the way down to 0/8 (Music service apk fails) but the Gear is still usable for calls.
