I have a CU7000 tv

Yesterday i got the problem which consists of :

Any app i would try to open it'll redirect me to its page on the app store as if it's not installed and the install tab wasn't functional and it gave a message under the install button says "Smart hub is being updated. Please try again later."

I fixed it by doing an EEPROM and here's how :

1 - hold the physical power button on the tv for more than 3 seconds

2 - within 10 seconds hold the power button on the remote control untile the tv starts

The tv should reboot at this point, wait for it and finish the installation

After that you should be able to use the pre installed apps normally but the app store will need an update, just give it a while and it should be good to go

Just note the the eeprom is a reset so make sure to save your channels, photos,etc

Thats what worked for me, hopefully it helps someone

Peace..
