[Moto Maxx Original Android Development] ChazzMatt:
Actually it does mean it's true. It's a felony to lie about communications stuff (radio transmitters, etc.) to the FCC, who is responsible for keeping the airwaves clean for emergency, military, commercial AM/FM/TV communications.

If Motorola says the two different Quarks have identical antennas, they have identical antennas -- as well as other identical hardware specified in the declaration to the FCC. Not sure why you are arguing about this. :rolleyes:

READ the Motorola letter to the FCC.

While the letter to the FCC mentions all the Quarks share LTE bands 2 & 4, it does not mention they also share LTE bands 3 & 7 -- because the FCC does not care about nor test for LTE bands not used by U.S. carriers. LTE bands 3 & 7 are used in Central and South America, not the U.S.

Also, the letter mentions the GSM/WCDMA (HSPA) bands the two models share, but of course the FCC ID IHDTS6PK2 (Moto XT1225) model has MORE HSPA bands and also more LTE bands. ;)

FYI for others following the discussion:

There are basically two Motorola Quark devices (two different FCC IDs), sold under three model names: Droid Turbo, Moto Turbo, Moto Maxx. All have the same hardware, but different radios.

_______

FCC ID IHDT56PK1

Droid Turbo XT1254 (sold by U.S. carrier Verizon; 32/64GB internal memory)

U.S. Moto Maxx XT1250 (sold by U.S. regional CDMA/LTE carriers; 32GB internal memory)

____________

FCC ID IHDTS6PK2

"international" Moto Maxx XT1225 (64GB internal memory)

Moto Turbo XT1225 (sold in India, but identical to Moto Maxx XT1225)

I live in the U.S. but have THREE "international" XT1225, as it has ALL the U.S. carrier AT&T LTE bands (2,4, 5, 17), plus all the Brazil LTE bands (3, 7) when I visit Brazil (my wife is Brazilian).

It's been answered many, many times. I know, because I've answered it many, many times! :cool:

THEORETICALLY, editing the NV values of one Quark could add LTE bands the other Quark has, but cannot add LTE bands neither has. You can't add LTE band 20 for Europe as neither Quark has that band. However, possibly you could add LTE band 13 to the XT1225 (since the XT1250/XT1254 has it) and LTE bands 5 & 17 to the XT1250/XT1254 (since the XT1225 has those bands).

But it depends on Motorola's manufacturing process. Samsung, One Plus, and others seem to make a "global"/"universal" template (almost like a super Nexus phone) on their Snapdragon chipset Androi phones, then disable the LTE bands not needed for a particular region or carrier. People have been able to use software like QPST/QXMD and similar to edit values to re-enable those bands.

But those bands have to be there in the first place, and yes the antennas have to support those bands.

Our Quarks all have identical antennas, so that's not the issue. The issue is does Motorola use a universal template like Samsung for the two Quarks --or did they two completely separate templates for the two Quarks? :confused: If the latter, in the XT1250/XT1254 there's no way to "enable" LTE bands 5 & 17 because they aren't there in the first place.

There's your answer. You are welcome to jump down the rabbit hole to enable bands -- but will not be successful if they used two separate templates. You're not going to get a different answer, no matter how many times you ask.

I researched this extensively and posted tons of screen shots when I used QPST/QXMD about a year ago -- before Motorola admitted LTE band 5 was indeed present on the XT1225 like the FCC found in testing. But for some reason Motorola refused to list it in official specs (when first released near end of 2014), until the XT1225 was later released in India in March 2015. :rolleyes: Also, Canadian users confirmed LTE band 5 in the XT1225 prior to Motorola admitting it. But initially it seemed LTE band 5 was there on the XT1225 in FCC testing and that Motorola had disabled it before releasing it. If so, then I KNEW it could be re-enabled! In reality, LTE band 5 was still enabled, but Motorola refused to list it in official specs for MONTHS, for some unknown reason. :rolleyes:

Once I had my answer I lost all interest in adding other LTE bands. I have all I need for AT&T.

I've been posting about these bands for almost 1.5 years now. It's no secret what bands the XT1250/XT1254/XT1225 have if you Google. ;) If you REALLY need AT&T bands, the phone to get is the XT1225. You bought the wrong "Moto Maxx". You went by the model name and not the model number or the FCC ID. Sell your XT1250 and buy an XT1225.
