Stuck on Startup

[s2tephen]

Hi
Nano 2T
Apollo 23 installed
Was all working ok
Turned off at back over weekend and when I turned it back on it lights up and shows startup on led screen and that's as far as it goes.

Have tried to reload the bootloader and image but is not going into the update mode stays on startup

any ideas

Apollo 23:confused: I guess is a typo...Try new image Apollo 012 for your receiver:)

I meant Apollo 003
And have tried several times does not recognise the USB will not go into update just stays on startup.
Someone said that it could be the flash memory is full and will not take the update?
No ideas
