720 Wont Boot - solved!

Here is a strange one !. Today I had a runtime error while trying to operate my TTom in HOME. As the device worked OK a couple of days ago I thought I would restore the device from a week old back up using HOME in case removing some bmp files had corrupted it somehow. Big mistake !.

Having carried out the restore I closed down the TTom using Safely Remove Hardware, removed the device from its cradle and pressed the start button.
It displayed the TomTom splash screen complete with drum beat but would not boot past that. I tried a reset with no joy. I made sure there was power by connecting it to the mains via the charger, still no good.

I read through some similar stories on this Forum but none seemed to fit my circumstances.

I reconnected the device via the cradle to the PC and it booted into the PC mode so that I could see both the internal and SD card memory.

Having no idea what could have caused the problem I thought 'horlicks' to this and re-installed the navcore. That solved the problem and the system is now up and running.

Just what caused the original problem I have no idea other than a corrupt backup made through HOME. I have now deleted that backup and with confidence in HOME destroyed need to consider making a straight backup copy using Win XP or something more reliable. I would be grateful for any suggestions.

I know that we NEVER suggest using Home for backups/restores.

Thanks David, I wasnt aware of the posting or of the HOME's disfunction.

I have backed up my device exactley as your post describes and cannot see the point of keeping HOME on my computer.

Thanks for your advice.

Paul

You still need Home to get updates of gpsquickfix files, mapshares and map updates.

If you aren't receiving GPSQuickFixes any more, there's usually a simple "fix".

1. Using Windows Explorer browse the TT's own storage and find the folder called "ephem".
2. Delete any files inside that folder.

3. Next, on your PC's hard drive, go to the folder where Home stores it's downloads and find the folder called "ephemeris".
(usually that's C:\Documents and Settings\username\My Documents\TomTom\HOME\Downloads\complete\ephemeris)
4. Inside that folder will be several folders called "QuickGPSfix", "QuickGPSfix-1", "QuickGPSfix-2" etc.
5. Delete ALL of those Quickfix folders.

Next time you connect to home, you should find the GPSQuickFix download is working again.
