not being rude, i dont think youll ever get e unless you buy an identical one  and grab if possible  the files

maybe the memory is corrupt,  WinCe on many device self extract in the memory before running

Corrupted flash is common in cheaper devices that usually weren't built with good flash anyway.
Will need more info on the device and what's inside; you may be able to find compatible firmware online as many of these are based on the same reference design.

Yes have another similar unit and have image of the GPS software. The main issue is the winCE os thats corrupted Wonder if there is a method to reinstall the winCE With Android boxes an update is achieved by inserting a sd flash with a upgrade file. So it there file for winCE OS?

i think you need to read about mce    you will learn how it work

normally wince 6   work  with a compressed file named nk.bin   or else 

on different companies they loved changing the bin extension file or simply renaming it  to confuse people

some companies had  flashing tool(s)

you need to find what works in your unit ...  and usb flash  can or could work,  BUT   it depends on how the companies implemented that

if you have corruption,  it get from somewhere in your unit ...

nowadays   working with WinCe is a pain in the .........  you need development tools, platform tools  etc ...


you need to find Mediatek tools / flash tools  etc ....
