Fans of the Google Nexus 6 by Motorola have been quite perplexed these past few days, ever since multiple builds of the same Android 5.1 update have been appearing. So far, LMY47D, LMY47E, LMY47I, and LMY47M have all reared their ugly heads, although Google has only posted factory images for the first two.
To make matters more confusing, AT&T and Sprint users have received LMY47D as an OTA update, T-Mobile users have received LMY47M, Verizon is apparently shipping the device with LMY47E, and international users have received both LMY47D and LMY47I. LMY47E appears to have the most updated radio, although some users are reporting better radio performance with LMY47E, while others report worse performance.
However, in spite of this big mess, a little birdie has tipped me off that Google expects to have all of these various Nexus 6 builds unified in a future OTA update, although we don’t know yet when that will actually occur. Apparently, Google allowed each carrier to test slightly different builds on their networks before approving the update, which accounts for these differences. Luckily, it appears that the actual software ROMs are identical across devices.
So that’s the story. For now, I wouldn’t worry too much about which version you choose to flash or which version gets sent to your device – it will all get sorted out in a matter of time, and there really aren’t any earth-shattering differences between them.
