Amazfit Gtr2 stuck on Logo - Amazfit Watch faces gefunden
My solution is very simple.
1. After I get a boot loop,
I always never uninstall/reset/hard reset or anything
except I put the charger on the watch, and the watch should be charged.
2. Take a look at the time display on the watch, it should shows the same time with the phone. That means the watch still connected/sync with the phone but it can't boot until finish because there is something wrong with the WF file that I have installed.
3. Run the Amazfit/Zepp App on the phone.
4. Swap down in Home Menu to refresh/sync the watch with the phone untill finish.
5. Choose find device, in Enjoy Menu in Amazfit App (I don't know where is the "Find Device" tools in Zepp App)
6. Try it again from No. 4 if the watch does not vibrate until the watch is vibrating.
7. Go to Profile Menu and change the watch face with the standard WF in the Amazfit/Zepp app.
8. Wait until it finish installed, and showing the standard WF from that app.
9. Then everything is going to normal again.
