Thread: TomTom Clear Flash Tool

UPDATE::

I've been in touch with Tom Tom Support and had the following, which didn't work and still gave me the screen freeze/reboot at the set time setting.
Might be of use to someone?:--


This issue can be caused due to some corruption in the application software.

We need to remove the application first and then reinstall a new application via TomTom HOME.

To do this please follow the steps mentioned below:

STEP 1 - Backing up your TomTom device.

- Click ‘Manage my device’ in TomTom HOME and select the ‘Items on device’ tab
- Select ‘Maps’ and ‘Postcodes’
- Click ‘Copy items to computer’
- Close HOME

STEP 2 - Delete the Application from device

- Connect the device to the computer and open TomTom HOME
- Go to Manage My Device
- Click 'Items on my device'
- Select the 'Application' and click 'Remove items from device'

STEP 3 - Delete the Applications from the computer

- Go to Manage My Device
- Click 'Items on computer'
- Select the 'Applications' (there may be more than one)
- Click 'Remove items from computer'

STEP 4- Check the device memory for errors:

Windows:
- Click Start > (My) Computer > right-click on the icon for the TomTom device
- Click Properties >Tools tab.
- Under Error checking click Check Now. Tick both boxes and then click Start

Mac:
- Go to Applications : Utilities : Disk Utility
- Select the device / memory card in the left pane and then click Repair Disk

STEP 5 - Re-download the Application

- Go to Update My Device
- Select the 'Application' (it may be pre-selected)
- Click on Update and install
- Repeat this process until no more applications are offered.

I look forward to hearing from you soon.

Please let me know have you made any progress or not.

I then had the following from Tom Tom Support, which again didn't work, but might be of use to someone.
It details backing up, formatting and reinstalling.

I would request you to format your TomTom device and check if it resolves the issue.

If you haven't already done so, please download and install the latest version of TomTom HOME from [Only registered and activated users can see links. ].

STEP 1 - Creating a backup of your map

- Charge your unit for at least two hours (preferably via the home charger)
- Perform a reset on your device (see: [Only registered and activated users can see links. ] )
- Connect your device to the computer and turn it on
- Open the Home software, go to page 2 and press on the "Manage My Device" (Go, ONE, XL) button.
- Tick Map, Postcode and Speed Cameras and then press on the "Copy to Computer" button

IMPORTANT: We advise you to follow the next steps ONLY if you have made a successful backup of your map.

STEP 2 Format your device

- Open My Computer; you will see the TomTom device as a removable disk drive.
- Right click on the TomTom device drive and choose 'Format' (Please make sure quick format is not selected)

On a Mac:-
- On a Mac, you can format the disk via 'Disk Utility', Select the TomTom drive and select 'MS DOS File System' and press erase.
The application can be found under Applications > Utilities > Disk Utility

After the Format has completed, please disconnect your TomTom device from your computer.

It will now have a red cross on the screen.

STEP 3 Open TomTom HOME

- Log in to your account with your email address and password for your TomTom account.
- On Page 2 of TomTom HOME, click on ‘Manage My TomTom -> Items on Computer’
- Tick the option for ‘Applications’
- Tick the option for ‘Voices’
- Click on ‘Remove Selected Items’

STEP 4 Install the Application

- Reset your TomTom device as shown on [Only registered and activated users can see links. ]
- Connect it to your computer and THEN turn it on
- HOME will now search for updates automatically. If not please click on “Update my Device”
- A list of updates should appear
- If there is a TomTom application (with the green puzzle piece icon), please ensure it is ticked
- Click on 'Update and Install'
- Once complete click on Done and your device should reboot itself
- Once it connects again it will look for more updates
- When you have a new list of updates please click on Back
- Disconnect the device by clicking on the Blue Eject button in the bottom right
- Now connect again and repeat STEP 4 to install any further Application updates until no more updates are offered

STEP 5 Restore the map back on device

- Connect device to HOME
- Click on Add Traffic, Safety Cameras, Voices, etc in HOME
- Click on 'Items on my computer' on last page
- Click on 'Maps' and select the map
- Click on ADD

Safely disconnect device from HOME.

This should resolve the issue.

It then goes on to say how to get the system info and to send TT Support that for escalation of the problem. of which there it is :-)

This is definately a digitiser problem.
If the cleaning does not help check the digitiser before you order a new one off Ebay (only a few bucks).
There are different models available and the sellers always claim they fit, so check the picture if the cable lenght and location match with your digitiser

I buy and sell and use Tomtom units. One hint to the problem you describe also manifests itself with a display on the GPS Navcore/Map Version screen screen of 32mb ram in a unit with 64mb ram. Another symptom will be if the unit is operated in Home under 'Operate My Device' and you will get only a partial map display...you will get the vehicle icon and colors, but the streets and the rest of the data does not load. You also may get a message like "No useful GPS data found near destination location" if you plot a route to a POI. I have four on my table now doing exactly that. Another symptom may include having to reset the language each time the unit boots or freezing when setting the time. The problem appears to be that either the hard drive is corrupting data written to it, or corrupt files are being written to the hard drive. I have restored one by wiping it, running a low level format with the HD Guru tool (free.) Then when all data is off the drive, run clear flash four times. I can attest to the file corruption because after I run the chkdsk utility on the GPS hdd and it says no problems, after I try to execute a command on one of the flawed units, and check the disk again, it will report fixing more corrupt files. So you then begin to assess a salvage value to the components: used 5" working screen and digitizer $20-$25, housing, fascia, battery and speaker $5 -$10. I tend to keep them around for parts. At first I thought the map file was corrupt, but that proved not to be the case. You can reload Navcores until dawn and it does not help. There is no fix for most units that present with this problem.

Just a quick one, what does this tool ACTUALLY do? I haven't come across a good answer anywhere...
