Don't know if anyone can help me, or wether this is the right forum to try 

But I have a gps withe a Windows ce 5.0 .net operating system problem.
The Gps goes to start screen, but goes no further. Active sync doesn't work anymore either so there is no access through laptop.

It all started after reading a forum on the navsoon 3775 with chinese wince 4.2 that looked exactly like the one I have, as it did not come with any documentation other than how to use the nav software.

The forum gave an update to change the chinese os to english, so I loaded it. (stupid me)
Now I have a gps that doesn't work.
I've tried to find bootloader programs to run through through the sdmmc card  to no avail. and have spent many hours looking through forums such as this to find an answer, but no luck. although spending a few hours reading through this forum I might have a better chance at getting some answer.

I have researched further and have found the correct model and the who had manifactured it, and have emailed them as well as the supplier for any answers. (that was two weeks ago)

Here are the specs for the GPS:
