You have to change the chip ELM327 inside your interface,
as the manufacturer says on their website. You can`t update the firmaware inside the chip, only order a new one programmed with new firmware. ( v1.4b )
Look here, this is their website :

Why Clone ?
The ELM327 v1.3a is still available!
Version 1.3a of the ELM327 is still available for purchase, at a lower price. This IC was great value for the money before, and now offers incredible value. It has more features than most people can use, so you will not go wrong if you pass over the v1.4b and buy this one instead.
The main difference between the v1.3a and v1.4b chips is that the v1.4b offers the ability to go to a low power 'sleep' type mode. This is great for applications where it is preferred to keep the ELM327 connected to the vehicle (fleet applications, etc.). If you only want to occasionally connect to a vehicle to read trouble codes and maybe a little data, then seriously consider this v1.3a version.
