TomTom GO 6200 to 6250 Professional

Postby yanez666 » Sun Nov 09, 2025 10:40 am

Good morning...
I'm trying to convert a Go 6200 to a Go 6250 Professional, not for profit but simply for passion.
I replaced the OEM, UserData, and Recovery partitions, taking the files from a Go 6250 Professional.
The system has changed its name and is now called 6250 Professional.
When I turn it on for the first time, it's effectively a truck navigator, but the first time I connect,
it returns to normal.
I tried regenerating the certificates, but to no avail.
I tried a system restore, but to no avail.
I tried applying the patch, but after the restore, it returns to normal.
I'd like to try installing Navcore 24.102.0003.411 in ttpkg, after deleting the Data folder,
hoping that it generates the correct certificates.
I think it all revolves around the two certificates TT_cl_auth_cert and TT_cl_prv_auth.der.
Can someone help me understand this and, if they have it, send me the Navcore 24.102.0003.411 file in ttpkg?
