Manage to update it. Here’s what I did
Instead of version 2.11, I downloaded and installed SAM-BA 2.13 from this link http://www.atmel.com/tools/ATMELSAM-BAIN-SYSTEMPROGRAMMER.aspx
Instead of the CommandPrompt.bat file, I used the Update.bat file located in C:\Program Files (x86)\GHI Electronics\GHI NETMF v4.3 SDK\Firmwares\G400\Loader
Below is the print screen of the batch file when launched correctly.
