Your TT stopped working for no reason?
A new map or Navcore was installed and now nothing works as before or reboots?
You only see a note to remove the SD or a red cross?
Well, firstly: you can't brick a TT, unless you really try it with the right know how
They are pretty safe in terms of noobs playing and breaking them and I will show you some ways how to do so - or better how to fix after fun was over.

If you did the right thing and have a working backup of your device you can skip this, delete all from your device and put your backup on.
Note: Home does not make a full backup of your device! You have to do it manually using Windows Explorer!


1. Topic : Rebooting after a new map was installed
This is usually caused by your favourites if you copied them to the new map or if they got corrupted.
If you don't really ned them (and your last destinations) you can delete the file "mapsettings.cfg" inside the map folder and it shoud work fine again.
In case you want to keep them start Home and click on "operate my..." to start the device simulation.
In there you create a new favourite or delete an used/old one and after going back to the map screen end the simulation
Home has no changed the mapsettings.cfg so that it conforms with your installion and again all should work fine.

2. Topic : Rebooting not working at all after a new Navcore was installed through Home
The best way to fix is to delete all from the device except your map folder and folders "voices" and "LoquendoTTS" - or you make a backup to your PC using Windows Explorer.
Now update your device through Home until no more application updates are offered.
In case you use maps from the forum you have to patch the Navcore using FastActivate.

3. Topic : Rebooting or not working at all after a Navcore was installed that is not designed for your device
Best option is to proceed as described in 2. Topic.
If you don't want to use the original Navcore check the instructions in the thread where you downloaded the Navcore - often a tiny mistake can ruin the whole experience.
Make sure the Navcore you try to install can work on your device - this goes especially for XL and X10 devices which are known to be quite stubborn.
SE versions often need "tweaking" using the switchfiles - check the instructions! There is a readme or readmenot included, in there are all switches explained.

4. Topic : Red cross, hanging rebooting after certain menu options were used
A red cross or a device that won't go past the splashscreen has either corrupted files or the Navcore was not installed the correct way.
Only in very rare cases physical damage to the flash memory is the cause.
Start with a hard reset, followed by the TT Clear Flash tool - Hard reset : hold Reset for 30+ seconds, if no reset button present hold the power button for 30+sec.
From experience doing the Clear Flash 3 times makes sure absolutely all unwanted residue in the memory is gone - don't panic! No data will be lost by using the Clear Flash!
Still no luck?
Do a checkdisk of the connected TT drive using Windows - if errors are found back up all files you need or the whole content. Delete all files and folders - don't do a format of the drive!!!
Make a clean install of the Navcore and map if necessary use FastActivate Premium for patching and activating.

If yout TT hangs or reboots when you press certain options in the menu the first question would be : Did you just install a new Navcore? If the answer is yes, check if you done it correctly or use a different Navcore.
In case all was working fine earlier (and you are 100% about it!) do a checkdisk of the connected TT using Windows and if errors are found do a new installation on a clean device - only delete the files and folders, don't do a format!
If no errors are found check the stuff that is related the the menu function or post a detailed description of your problem in the forum.

5. Topic : Preventing problems
Once you have a working device and all settings, voices, cams ect. are working the way you need make a full backup using Windows Explorer and Home!
The "latest" Navcore is not always the best! Many factors need to be considered especially for old devices and devices with only 32mb of Ram.
