2k Hardwired Doorbell still not working after FIRMWARE UPDATE

If any else out there is having problems with their 2K Hardwired doorbell feel free to chime in … : ) I just recently installed it Day before yesterday , but would not work properly till the firmware was updated. BUT the only problem with that was the firmware would not update. I tried many times and procedures but still would not update… after multiple attempts to update the firmware with NO SUCCESS I went on an Eufy comment center and read some comments about waiting until the software settled in… Sometimes during the day IT had UPDATED on its own… WELL after the update my doorbell is still not working properly all Hardware has been checked Bluetooth is working good WIFI is great, All components are communicating well… EXCEPT I AM NOT GETTING any video at ALL… I will JUST GET A DARK GREY VIDEO SAYING unable to load retry…!
