My pleasure! And thank you

For people who need to know.

Replacing LCD cables fix (95% of the time)

1. Boot loop

2. Watch stuck on snake

3. Watch turning on but not showing any battery

4. Watch taking very long time to turn on

5. LCD not working with device (LCD tested on other device and working good though)

If this does not work, replace the battery connector. The battery connector relays power information between the battery and device and replacing it fixes the "no charge showing but turning on" issue and sometimes boot loop also. If replacing LCD cable and battery connector does not work, there is something else going on with the device, or a pad was ripped when replacing the LCD cables (fix it with making a pad with wire be careful not to short by exposing surrounding copper)

Replacing the battery connector sometimes fixes the digitizer not working too, but this is rare. If the digitizer not working and you replaced it with an aftermarket one, you may need OEM (buy premium one on mobilesentrix). Some digitizers seem like they are serialized (for series 5 and 6), and cannot be fixed if not working I would suggest attempting to reset the device using the old digitizer if possible and then replacing it. I am waiting for firmware to be re-uploaded to see if reinstalling firmware can fix this issue when replacing the digitizer

Hope this helps somebody who is looking for this information!
