Thanks to both TomTom13E and biggerdave for providing the information and bootloader to update and bring back to life another TT One and setting me back on the right track!

1. Installed the bootloader 5.5120 from the above post by biggerdave to the root (internal memory) of my TT One Second Edition (v4) Now my TT One will see bigger SD cards

2. Formatted a 4GB micro SD card (with adapter) with FAT 32 file system

3. Installed the new Navcore v9.541 SE provided by minetraps in 1st post of this thread. It is important to install the navcore to the SD card if you are using an SD card or the TT will not detect the SD card.

4. Installed map United_States_1025_9436 to the SD card.

5. Boot the TT to create the ttgo.bif file. Make sure the ttgo.bif file gets written to SD card or activation will not work. May need to copy the ttgo.bif file to the SD card from the computers root (internal memory), I had to do that .

6. Connect TT to windows computer, I used the easyactivator6 program to activate the map, get from here -->[Only registered and activated users can see links. ]
if you use the easyactivator6 program you will need to add your meta code to the Meta.txt file because easyactivator6 is old.
7. This forum is always very helpful I really appreciate everyone here
