This is a recommended firmware upgrade, meaning that the features introduced by the firmware are important but not critical for the GSPS service including the network and the IsatPhone 2 (Model 2.1) handset.

Pre-requisites for installation

In order to upgrade the handset’s firmware you must have a PC running Windows 10, Windows 8, Windows 7, Windows Vista or XP.

STEP ONE
Download – USB Drivers

Please note, you will need to install the USB drivers first before connecting the handset to your PC.

If you do not do this, Windows will try to use another driver that is not compatible and therefore, it will not work.

DO NOT PROCEED WITH THE FIRMWARE UPGRADE UNTIL CORRECTLY IDENTIFYING THE MODEL YOU HAVE THIS FIRMWARE UPGRADE IS FOR ISATPHONE 2.1

Driver installation is a 3 step process

  • Download drivers
  • Unzip drivers
  • Install drivers

USB Drivers are compatible with Windows XP, Windows Vista, Windows 7, 8 and 10.

(For Windows 7, USB 3.0 is not supported.)

All three steps are detailed in the instruction guide.
