I never managed to have this trick working... :ee:
But there is a third way to fool TTH I have found and has been refined and tested with my friends at GBCNET.NET!!! :ok:
Each time TTH installs a real navcore it will create a file called Application.tlv inside the folder called program, if the device (like my GO750) has both an SD and the internal memory the folder is located where the navcore is installed.
This binary file contains info about the nc version and the files that TTH has installed. If this file is present, TTH compares this version against the official nc for the device and then decides to update it if it's different!
The long way to generate this Application.tlv file is to let the latest TTH installs the official navcore for your device, then using a Hex editor (I use HxD, very simple and available in portable version too ) you have to replace the version with 9.999 and save!!!
Here you are where to find the version to modify, this is my original file for my GO750

The short way is to download the attached archive which contains an Application.tlv already patched to v9.999 :ok: :ok:
