I have been searching for the v5.5128 Bootloader for my old TomTom One XL (4S00.000) for a few days but all the links I found were expired or didn't work.
Can someone reupload the bootloader so I can enable SDHC support for this old device? Thanks in advance

Bootloader_5.5128: [Please Register or Login to download file]

To update the bootloader simply copy the file named system to the root of your internal memory/or SD/or HD of TT then switch off and reboot.
If you want to use a SDHC (> 2GB) on device that hasn't a native recognition of it (ex. TT ONE) please update the BL before to use the SD > 2GB.

This bootloader worked great for my TomTom XL. It now accepts >2GB cards. Put in a Sandisk 8GB Extreme card and started a map download. Have to wait for 20 more hours since the downloads websites throttle the free tier like crazy. Thanks a bunch and I hope this will help some more people. Thread can be closed!
