This is my suggestion for a sticky topic:
There has been a recent run of MicroUSB cables which cannot be used for Jailbreaking AppleTV devices.
-
Some USB cables sold as charging cables are not real USB cables, and only have conductors for charging a phone. They cannot be used for data, and therefore cannot be used for Jailbreaking an AppleTV
-
Some USB cables cannot carry enough current to power the ATV Jailbreak. This can be true of very old cables, which were never designed to be used as a power source, and can also include newer designs with very small conductors, such as a ribbon cable or a very thin cable.
Any cable which is sold with a device that is designed to be connected to a computer for data and power should work. This includes cables sold for or included with Android phones (but not charging-only cables), with updateable GPS devices, cameras, etc. If your cable came with a device that can be connected to a computer to share data and provide power, it should work for jailbreaking.
