I had the same problem. What you do is place your finger in the lower right corner where the green button would be and cut it on. When the prompt comes up, click yes. when the no detailed maps comes up again, hold down the green button again. You should then be able to upload the maps.

I am very sorry to hear that you are having problems with the unit. You
may need to switch the unit on and press and hold the centre of the
screen until the message ?No detailed maps? message disappears.
If your map detail is missing, then the map information may have been
disabled. To check to see if the mapping has been disabled, follow the
From the Where to? and View Map page, touch the Spanner icon, settings
Touch Map Info.
The unit should display the name of the map that is loaded to the unit.
The box in front of the map name should have a tick in it. If it does
not, touch the box to place a tick in it.
Then please test by searching for an address.

The system bootloader software got scrambled when you did the update. You can escalate it to a software tech and they may be able to give you the bootloader image file. If not, you'll have to get an RMA and send it back for a unit swap.
