Firmware is software stored in the memory of a device such as a digital camera, which controls its basic functions. Manufacturers may offer firmware updates from time to time that fix camera problems found after its release.

A firmware hack is developed by a third party programmer. It is not authorized by the manufacturer.

When a hack is uploaded to a digital camera, it modifies the software. It increases camera functionality, such as adding a RAW file format to a camera that does not have RAW.

If necessary, the original firmware can be restored.

Does a firmware hack void the warranty?

Since a firmware hack is not authorized by a manufacturer, it may void a digital camera warranty. Some have reported sending a camera with a hack in for repair without a warranty problem. Either the firmware was reset to the original by tech support, or the repaired camera was returned with the hack still installed.

Should I add a firmware hack?

The decision is entirely up to you. Certainly think twice if your camera is still on warranty, which may also have an extended warranty if you paid for it with a credit card.
