[Verizon Motorola Droid Turbo Q&A, Help & Troublesh] ChazzMatt:
See, on T-mobile you do NOT need CDMA and you do NOT need LTE band 13. You don't need the Droid Turbo, you can easily use the XT1250 (U.S. Moto Maxx, clone of the Droid Turbo XT1254) or the XT1225 Moto Turbo/"international" Moto Maxx.

The XT1225 has more HSPA bands, more LTE bands, but does not have CDMA (which you do not need).

Most of the Quarks are called "Moto Maxx". Verizon calls theirs "Droid Turbo". In India, Motorola used "Moto Turbo". Yeah, it can be confusing.

The "Droid Turbo" was NOT NOT NOT an exclusive to Verizon in any way. The exact same phone was sold by other carriers here in the U.S. and around the world. Just like an LG G4 is sold to other carriers here and around the world. The "Droid" name was "exclusive" (and means nothing), the device was not exclusive. The U.S. Moto Maxx XT1250 has the exact same FCC ID, exact same radio bands as the XT1254 Droid Turbo.

No, there's no unlock bootloader in developer mode on the Droid Turbo XT1254. That's just to taunt you.

But all QUARK models are unlockable for FREE -- except for the Droid Turbo XT1254. Think of Quark (the model name) like an "LG G4" -- a device sold to different carriers all over the world, and some have different radio bands.

The Droid Turbo XT1254 is Verizon's name for their Quark. In India it was Moto Turbo XT1225. In other parts of the world, " Moto Maxx". SAME device, just different radio bands.

In the U.S. the U.S. Moto Maxx XT1250 has the same radio bands, same FCC ID as the Droid Turbo XT1254. It's the same, identical CLONE of the XT1254 and has easily unlocked bootloader (for FREE, through code given on Motorola.com) and will run on Verizon with a Verizon SIM card.

You acknowledge you give up your warranty, and Motorola gives you the code which will unlock your bootloader. (Again, only for the XT1225 and XT1250 -- NOT for the Droid Turbo, because Verizon demands Motorola keep the bootloader locked. Makes no sense.)

All the Quarks except for the XT1254 Droid Turbo can be unlocked for free via Motorola. Verizon made Motorola lock down their Quark.

The only way to unlock the bootloader on the Droid Turbo is an exploit Sunshine found which ONLY works on Verizon SUTL-44 firmware. If you find an XT1254 lower than that, you can carefully flash to SUTL-44, but do not let it update past that. IF you the XT1254 is already on SUTL-49 (which was pushed out in May 2016 to block that exploit), you are out of luck.

"SUTL" is Verizon firmware. The other Quarks do not use that nomenclature.

The XT1225 and XT1254/XT1250 all share LTE bands 2, 3, 4, 7.

The XT1225 additionally has LTE band 5 and 17 (more bands used by AT&T).

The XT1254/XT1250 instead has LTE band 13 (Verizon LTE band), plus CDMA bands. While it does have some HSPA bands, there's not as many as in the XT1225.

"dev" version of the Droid Turbo XT1254

otherwise the XT1225 (64GB) is the better phone for most people not on Verizon.

I've written about all this before:

Same information, just written slightly differently, maybe easier to understand.
