ViewSonic SC-T25 upgrade VTOS

This cost effective Thin Client is based on Raspberry Pi 3 and together with Stratodesk OS it is very versatile

If You bought, or got, the thin ViewSonic client, VT, produced before date 2017-07, You can upgrade to the better Stratodesk NoTouch OS with out any cost. This OS  is the "standard" OS for new devices.

To get the software follow this link

Here is the upgrade instructions. In Windows just follow the instructions in the link, but with Mac (or Linux) follow the instructions below.

So take out the SDCard and connect it to Your Mac.

Download the latest OS and unzip it. In the package pick the file lnx-2.40.2658-VTOS-k404-armhf-180114.bin and put it in Your root directory. (The last figures in the file is the date so this could change) This is the same directory as the one You start in when using the program Terminal

Start the program Terminal, on Your Mac, and check Your SD cards name type

$ diskutil list

and You will have something like

/dev/disk0 (internal, physical):                                              
   #:                       TYPE NAME                    SIZE       IDENTIFIER
   0:      GUID_partition_scheme                        *121.3 GB   disk0     
   1:                        EFI EFI                     209.7 MB   disk0s1  
   2:          Apple_CoreStorage Macintosh HD            120.5 GB   disk0s2  
/dev/disk1 (internal, virtual):                                              
   #:                       TYPE NAME                    SIZE       IDENTIFIER
   0:                            Macintosh HD           +120.1 GB   disk1    
                                 Logical Volume on disk0s2                  
                                 9519AF9B-4C53-41CE-BB98-1139A7C82D9D        
                                 Unencrypted                                
/dev/disk2 (external, physical):                                            
   #:                       TYPE NAME                    SIZE       IDENTIFIER
   0:     FDisk_partition_scheme                        *8.1 GB     disk2    

In this case "/dev/disk2" is the name

You now have to unmount the SD card.

$ diskutil unmountDisk /dev/disk2             
Unmount of all volumes on disk2 was successful

and then copy the OS to the SD card using the password to the Mac

$ sudo dd if=lnx-2.40.2658-VTOS-k404-armhf-180114.bin of=/dev/disk2 bs=16m

Check with Finder and You will see a nice structure of files and folders.

Unmount the SD Card and plug it into the VT.

Connect the mouse, keyboard, screen, LAN cable, power and the VT will boot and start the ”NoTouch wizard”. Configure with instructions from here and the main page here.
