As I stated previously, the file on the Matrix TV web site , "Matrix TV for Matrix V2.1 hardware", also works for me. But this download also contains an early version of Openelec. Guess there are not many users out there of my TBS2910 V2.3 that are trying to install the latest Kodi V15.2. I see no way to use an .img file to accomplish my goal since this file type does not contain a MfgTool2 file.
When the TBS2910 is in update mode it does not appear as an external drive. I have used a window based computer as well as the linux based program "Parted Magic" to confirm this. Therefore I assume that the MfgTool2 file. is sending the program information serially into the units on-board memory.
If you or anyone else knows how to load the TBS2910 V2.3 using a .img file please let me know.
