Earlier this morning T-Mobile support page listed Android 4.4.3 updates were heading out to the Nexus 4, Nexus 5 and Nexus 7 (2013). It brought up a lot of questions, like, will the unlocked versions be getting it. It is a given that the unlocked versions for those devices would be receiving the update, the news was centered around T-Mobile’s carrier versions. For those that might be a little bit more than irritated by the news, there is some other good news out there for you guys. Google has just released the Android 4.4.3 factory image for the Nexus 4, Nexus 5, Nexus 7 and Nexus 10. It does seem to be missing for the Nexus 7 LTE version though. The file size rolls through at 444MB’s and you’ll need fastboot set up to to get it installed.
