Potential problems with patching latest Navcore 21.2 and MDC

Simba

you can help lower navcore down to 21,100
I didn't do that
i don't have TTBS and i don't know how to use it properly
once i tried to upgrade my device to 21.100 manually
without result

2.- Double click on; TTB_ServiceUpdateTool.jar

I do not have this

I have always used MDC
and i want to go back to 21.100

look here, you have an explanation of using TTB_Serviceupdatetool.jar and download
choose download Navcore 21.1 or 21.2

The Winrar file you have is in the .jar format. You just have it associated with Winrar.

open .Winar and extract
remember that Java has to be installed on your PC

Hello, I tried using TomTom Service Tool to install Navcore 21.1xx on a TomTom Start 50 device. After I have clicked on the .jar file and selected the folder with the 21.1xx Navcore, after about 2 seconds the bar is at 100% and then stays that way. Nothing happens on the navigation system either. What am I doing wrong
