But once the 4.4.2 OTA is pushed, the factory images I have now would be out of date because those are for 4.4., right? Then will Motorola release 4.4.2 factory images later?
I have a verizon unlocked dev ed. Also, what does it mean when in bootloader mode it says Devide is UNLOCKED. Status Code: 3. What is the status code 3?
It gives you the stock recovery, the stock system image with all the applications, and the ability to update over the air (OTA). People re-flash the factory images either when they think they messed up their phone, or when they want the latest update via OTA instead of waiting for a SBF package. In short, it returns the phone to the default/non modded status.
I am fairly certain that a SBF will be made for 4.4.2, it just is taking a bit longer this time, maybe they are busy, especially since there is no new updates around the corner any time soon. Since you have already updated to 4.4.2 (like myself) there is no way to go back to stock unless you have made a recovery image in TWRP/CWM. Then all you have to do to update, is reflash the stock recovery image and then you can take a system OTA.
The bootloader on this phone cannot be downgraded, due to the eFuse
system incorporated into it. If you attempt to load a lower bootloader in RSD Lite, it will simply fail to install and nothing else bad will happen, however, if you force the bootloader overwrite then you have a nice new paperweight (aka hard brick), because this trips the eFuse.
Status code 3 is basically the computer flag telling the future firmware updates that your bootloader has already been unlocked, so if you update using that same carrier/firmware, you don't lose your unlocked bootloader status. Another reason why you need to simply stick with your own firmware. As there have been reports that loading another regions/phones firmware can lock your bootloader again because the flag isn't there.
