I’m a big fan of what Mark Skippen from Skipsoft.net is doing with his toolkits and recently he released a Unified Android Toolkit for the Galaxy Nexus, Nexus 4, Nexus 5, Nexus 7, Nexus 7 and Nexus 10 with support for Samsung devices coming in the future. Instead of having to download each of his toolkits for each of your device he’s combined them all together to make the Unified Android Toolkit. Currently he’s having some trouble with Android 4.4 and his toolkit identifying them on the Google Developer Factory Image download website and promises a new version asap to address this problem. Mark’s toolkits are developed as donationware so make sure you donate and get access to additional features including automatic updates. The current version of the Unified Android Toolkit is v1.0.0, you can head over to the XDA forums for updates.
