New gimgunlock-0.03+MapSigPatch - Windows version Latest release

As usual drag&drop the img in it to unlock it.   as shown below figure

It unlocks NT (not NTU) IMGs in some 2014 devices, but not working with all new devices 2xx9 and probably in most of newer devices firmware */** read note #5 
If you have 2xx7 (8) (PartNumber> 006-B1582-00), works
If you have 2xx7 (8) (PartNumber> 006-B2077-00), doesn't work.

*NOTE 1: If you updated a 2014 device firmware recently and maps stopped working the only one solution is to downgradeits firmware (if available), because these new devices/firmware have improved checks, NT maps to work must necessarily contain a valid digital signature. (if removed by new gimgunlock+mapsigpatch map wont work)
To rollback see here
Maps created by MPC with invalid license won't work in these devices.
In zūmo590, GPSMAP64, Edge1000, NT maps unlocked by New gimgunlock-0.03+MapSigPatch will work, Maps with Unicode codepage (65001) won't work.

* Direct Modification - unlike other tools which use GMapTool to split an image file, unlock each tile, then join all tiles; this tool unlocks all tiles in an image file directly without splitting and joining. Therefore, you should back up your original map first before running this tool.

* Super fast speed - The 1st result of direct modification is super fast unlocking. For example, a 2.3 GB image file can be unlocked in less than 4 seconds.

* Zero disk space - The 2nd result of direct modification is that no intermediate disk space is required. In fact, you can unlock a big image file on a SD card or USB connected GPS device directly and quickly.

* Intact header - The 3rd result of direct modification is that the original header of the image file is preserverd. Thus, timestamps, version number, Mapset name, etc. remain the same.

* Less memory used - this tools runs happily on Win32 without the need of 3GB switch.

* Multi-platforms support - this tool is distributed with Windows binaries. But those who prefer to run on Mac or Linux platform can compile the source code by themselves.

* Ease of use -

  to unlock, simply drag the image file over the icon of gimgunlock.exe, 

the dragged file will become unlocked. That's all. You can also run it in a command prompt window or batch file by supplying the pathname of the image file as the only argument.
