Moto E 2015 open source files released today
This will probably interest you developers out there and, if you are intrigued and eager, you can head over to Motorola GitHub (link in source) to find and download this package or any other Moto package that interests you (and is available at this time). After downloading the files, you can start tinkering with the source code to create beautiful ROMs, better recoveries and apps for instance.
Attention: this is not the package for the AT&T Go phone or the Verizon prepaid Moto E.
