Dont upgrade its standard offshore rep nonsense. What "green light stuff" exactly? Iz it just the wifi lights or does the base power light go from white to green and flash maybe?
Can you try the pinhole reset again as it can be tricky - do it the way below.
Also did you try the "local known fault line" 0800 561 0061
If none of this helps we can take a look at your Hub stats
-----------------
Disconnect any ethernet cables from the Hub (leave the coax connected), and then with the Hub still "switched on" throughout, press reset pin in firmly with paper clip/SIM tray tool or similar "thin thing" and hold it firmly at the stop point for at least 60 seconds, release the pin, leave Hub for 5-10’ to stabilise - dont manually switch it off at any time. See if that sorts it.
