Wont Boot Properly - 53296 on Front Display

[Hebridean]

Sorry but dont have the build number because machine wont boot up properly.

Tried to install Unicable LNB but couldn't get it working properly so reverted to standard OCTO LNB.
Kept getting message abot Channel B being configured incorrectly - eventually was able to scan both channels.
ABM kept failing.
Tried to reboot a number of times without out success.
Switched STB off and then back on and now displays code 53296 on front display.

Image 5.1.030
Kernel 4.10.6

This 'fault' appears to have rectified itself. I will keep an eye on it and post back here it it reappears.

Did you install some long channel list or something like that?
