I have a Apple Watch Series 2. The screen cracked so I bought a new lcd from fixez. I changed the screen but I can’t get it to work. I think the watch powered up because I felt a vibration and my phone connected to it. I tried to update it but that did not work, so I deleted the watch from the iPhone and now it is completely dead. Anyone have a idea what do to? I tried disconnecting the screen and attaching it again, but still the same.
Try putting on the old screen, then do a WatchOS update (and an iOS update on the iPhone) and after that reinstall the new display and see if if works. It is also possible you got a faulty display.
Did the old LCD display? if so try that you may just have a faulty replacement screen, also triple check the connectors are in tact. Hope that helps
