# Testing is the new stable
There are two types of images on the port git repository: one has "-testing" appended to its name, the other has no suffix. Don't get fooled, the images with no suffix are actually the development images, which can break for all sort of reasons depending on what the porters are working on. The "-testing" images really are what you're looking for, unless you know what you're doing. This is indicated in the flashing how-to.

However, if you got it wrong initially and flashed a development image, you do not need to flash again. Here is how to switch your device to testing.
