[Q] Is there a way to enable 900/2100 3G bands?

Hi all
I just got this phone for use in Italy, and am now waiting for my unlock code to come through.
Meanwhile, and as the main question, I wonder if it ever will be a way to turn on the WCDMA 900 band that we use here (along with WCDMA 2100), since it's not supported out of the box, being an American phone.
I would like it to be a 900/2100 phone, instead of 850/1900/2100.
I'm sure the phone supports it (being much newer than my current Motorola Defy that's able to do it), it just has to be unlocked somewhere.
Any info is appreciated!
Thank you

Sorry, but that is not possible as the hardware does not have those radio antennas in the phone. This is ONLY a GSM/HSDPA+ phone not a WCDMA phone. There is not a way to change that since it is a hardware antenna change.

As far as i know (pretty sure on this), all 3/3.5G is WCDMA. HSDPA(+) is WCDMA. WCDMA is just the name of a RF modulation, and 850, 900, 1900, 2100 are just the bands the protocol can run on.
In fact my question could just be translated to: as these settings are stored in the baseband rom, we need to flash an alternative baseband to enable those, or discover where they are set.
I guess a motorola phone similar enough to the A2 (i.e. same.hardware) should suffice as a "donor" phone for the baseband rom. May be an ipothetic european A2 of the future.
Has a phone like this been found yet?

The hardware on A2 does not support this, the antenna is not setup to capture these frequencies. Just because the baseband is in the rom does not mean that you can change the hardware.... Yes technically all 3G boils down to WCDMA or CDMA technology, but there are major operating differences between even the different spectrum in them. The issue you have is that the phone is not going to be able to capture those on the hardware layer. It is similar to trying to get am radio signals on an FM radio, with an FM antenna.

Well I hope you are wrong
I think (hope) motorola has put an universal antenna on the atrix 2, it'd be anti economic to do otherwise.
BTW, 850, 900 the antenna differences surely are minimal.
It sounds more like as a RF chipset limitation on the simultaneous bands used... like three of em. "Tri-band umts".
As with the good old gsm phones marketed as tri- or quad-band, like my v525, the actual bands used were depending on where you lived.
All of this, i hope...

Did you buy an MB865, or an ME865, as they have two totally different antennas. mostly we discuss the MB865 in here.... and I can tell you that there is no way to change the MB865, because it setup that way on purpose, and locked to AT&T's signals via the antenna and wireless chipset, by Motorola. The ME865 might be a better choice I think there are two versions of that one, one is the Chinese version and the other is more international.

ME865 it's for asia only. Motorola phones found over here follow the MB nomenclature. I have got an at&t MB865.
Anyway if a €300 phone (defy) can do that, I don't see why motorola would have chosen to spare on a $ .5 part on a €550 phone (euro price tag estimation), and have to redo a whole new pcb layout if the MB865 ever comes to the old world. Even taking into account the at&t exclusivity. It's anti economic for them.
Btw I don't want to be right at all cost, please don't misunderstand my words. ;-)

Also if you look at pdadb you will find two.models, mb865 and mb865a.
I don't know if they're both real or not, but they are identical specs-wise the only exception being the lack of wcdma900 band on the "a" version.
If such version actually comes to market, i guess a baseband transplantation could be done...

Any chance to enable all LTE frequency supported by MSM8960?

Dear All,
I recently got this device in Hong Kong and is hapi with its performance!
But I am still wondering if this device could actually use the LTE available in HK?
I knw the msm8960 claimed to be capable of utilizing all frequency of radio,
so is it possible that there is some soft lock in the baseband?
Could i flash the baseband or replace the modem driver from other device to access other frequency?
any idea is appreciated!
Thanks!

I think it has to modifiy the ROm and the hardware

I tried to figure out, if our Photon Q is supporting more LTE bands than 1900 MHz (#2 or/and #25).
-> http://en.wikipedia.org/wiki/E-UTRA#Frequency_bands_and_channel_bandwidths
On some sites there are reports for having another band. (Have to search again, I think it was 850 MHz, #26 or 700 MHz, #12/#17/#29.)
I have also searched for supported frequencies for MSM8960.
I found some BlackBerry devices based on that SoC and 2 different versions of supported LTE bands.
One version (UK) supported 4 in europe used bands und the other version (US) supported 4 in US/Canada used bands.
I think that the Photon Q is like the BlackBerry US version and supports 4 LTE bands in US/Canada.
If you need a few sites, I will search again and show it to you.
The strange thing is, if I set to LTE only (via 4636) I can see all 4 carrier (germany).
We have 3 bands with LTE on it, but I can only get signal to max 2 of them.
Band 3, 7 and 20 (1800, 2600, 800 MHz).
The weird thing is, that on band #20 (800 MHz) only 3 carrier are active, so it has to be band #3 or #7.
Maybe I'm missinterpreting things and thats just a sideeffect of crossing bands of LTE US and UMTS Germany.
On stock ROM there was another "secret phone code" to see what the phone-part is doing. (From qualcomm I believe.)
I think I will test it some other day, to see which band is active.
At last, I was never been able to "login" or "register" into my carriers network within LTE.
Please discuss about that possibility, I really want to find out, which frequencies are supported by our phone on LTE.

Dear Loader009,
Thanks for your information! I'm really impressed that you could actually search the carrier in 'LTE only from Germany!
Could you please share the version of ROM you are using?
And if possible, any screenshot? I really want it can be used in HK with LTE(1800, 2100 & 2600Mhz)
Also do you have more information about the secret phone code? I think it would be interesting
Actually, I noted that xt925 and xt905 are using the same chip MSM8960 with LTE usable in HK.
Is there anyone can locate the radio/baseband of their rom and port it for XT897?
I am willing to try it with my machine.
If this work, I think we could use this photon q all over the world!
Any idea?
Regards,
Vasco

Of course, I was just blind guessing the hardware for xt926 and xt907 are using the same hardware.
If not, there should be one chip controlling the modem channel of the device to be replaced.
But WHICH ONE???
Any expert in this area can solve this question? I am a dummy for radio stuffs

This seems like it's getting pretty interesting.

Dear all,
I'm also very interested in this topic since I imported a Photon Q to Germany and was wondering if it's possible to use the local LTE 800/1800/2600 bands.
I think the first thing we have to find out is whether the hardware is capable of using other bands than the 1900 band listed on the Motorola website. As Loader009 states he could see LTE carriers which are known to use different bands I assume the hardware can do it. Otherwise the carriers wouldn't have been listed, right? Maybe someone from another country with different frequency bands can check and confirm that he can see those carriers as well?
Thus, the limitation to the 1900 band should be software-made and could be modified by a developer. I hope someone can participate at that point as I don't know much about coding...

I'm using CM10.1.
I can't remember the secret phone code, I have to do research again.
This secret phone code only works on Stock ROM. (I stupidly deleted it, when it wasn't working on CM10 anymore.)
The one secret phone code I used to force "LTE only" was *#*#4636#*#*.
Please DON'T change the baseband (don't even tap on it).
This can do problems to you. (I had to use QPST to recover the supported frequencies.)
Also, developers (afaik) can't modify the modem firmware.
We also don't even know, which LTE bands the Photon Q is capable of. (Except 1900 MHz)

I've got my 32GB SDCard back and will test it in the next few days out.
I hope I'll find that secret phone code, I'll also make a few screenshots.

Got the code!
##33284# <- ##DEBUG#
It only works on stock afair!
I'll test tomorrow, it's about 3am now >.<

I have read the "QU_SnapdragonS4_White_Paper_FNL_Rev6.pdf" and found there following entry:
-----------------------------------------------------------
• Industry’s first fully integrated 3G/4G world/multimode LTE Modem: <<<Supports all of the world’s leading 2G, 3G and 4G LTE standards>>>.
It also includes integrated support for multiple satellite position networks (GPS and GLONASS) as well as short range radios via Bluetooth,
WiFi, FM and NFC.
• Designed for speed, compatibility and power savings:
Snapdragon S4 Processor MSM8960 chipset includes the industry’s only complete platform that integrates all of the world’s leading 2G, 3G and 4G mobile broadband modem technologies on a single chip. This new integrated multimode modem is based on an advanced, programmable architecture that is performance, size and power optimized for the fastest combination of modems available for:
- LTE FDD/TDD (Cat3)
- 3G (DC-HSPA+ Cat 24)
- EV-DO Rev. B
- 1x Advanced
- TD-SCDMA
- GSM/GPRS/EDGE NFC.
Multimode/Multiband Means Worldwide Coverage.
• Support for multiple radio frequencies: Mobile broadband technologies are growing increasingly complex in their implementation. LTE is currently being implemented in over 40 diff erent radio frequency bands throughout the world. To complement its wide range of modem standards supported, Qualcomm has designed the Snapdragon S4 Processor MSM8960 CHIPSET platform to <<< address all commonly-used frequencies (from 700–2600 MHz) and bandwidths up to 20 MHz>>>, allowing its customers to address any mobile network opportunity whether the simplest single frequency implementation to the most extensive multi-frequency global mode, whether 4G, 3G or 2G.
-----------------------------------------------------------
Based on the document the chip can handle all LTE Standards, but it depends on his "advanced, programmable architecture"....as written there and how Motorola / Sprint implemented this, maybe they reduced LTE only to one Standard.
I don't have LTE in my area and so I cannot test this.

That's possibly right.
Something else:
If I remember correctly, somewhere in this forum have been said that for CDMA the internal Sprint "ID"(?) is used.
Maybe that's also the reason why I cannot connect to LTE in my area.
The phone is trying to "login" with the Sprint ID and this of course won't work.
The ##DEBUG# menu wasn't helpfull. It shows frequencies for american standards and not for GSM/WCDMA.
Also the LTE menu is also not very helpfull, it doesn't show frequencies at all.

Any News on this topic?
Maybe one of the developers can give a statement?

Yesterday I tested a LTE compatible SIM card.
My Bro has a Samsung Galaxy S4 with 4G/LTE in my area.
So I've put his SIM-Card into my Photon Q and set LTE only.
I had no luck, the Phone couldn't register into the network for this SIM.
I guess either it has the wrong frequencies or LTE is for inbuilt "SIM" (Sprint SIM?) only.

The latter. LTE is configured only for 1900 MHz which Sprint uses.

LTE is configured only for Sprint's frequencies, however, it supports the United States frequencies of PCS blocks A-G. The G Block is Sprint's current LTE channel, and they may deploy it later on Blocks A through F, depending on if they own the spectrum in a given market. The reason you see EU networks when the phone is in LTE Only Mode is most likely because the Phone still sees GSM signals, but will only connect to LTE ones from those GSM signals. Likewise, in the US, if you force LTE Only and then search for networks, AT&T and T-Mobile US will come up as the GSM carriers the Photon Q sees, rather than the LTE signals it sees.
Setting the Photon to LTE Only will not do anything for LTE in the EU. I suspect that if another carrier in the EU uses the 1900 MHz for LTE, the Photon Q will have no issues connecting to LTE in Europe. But until that time, be happy with HSPA.

Can this configuration theoretically be changed / other frequencies be added?

IIRC The only place with 850mhz LTE available is the Chicago market and currently no phones at all support it. :crying:

[Q] Add or unlock LTE bands

I bought the american version of the Nexus 5 even though I am on the middle east (for price reasons). Since the snapdragon 800 chip support all LTE bands techniclly speaking, could I activate certain ones to work for me through firmware or modem modification?

Not at the moment,
There are people who believe that it will never be possible due to RF hardware differences between EU and US models.
There are people who believe that a modem firmware hack might unlock some LTE bands in the future.

Well I was hoping for a onesided, positive reply, but I guess you are right, we will wait and see.
What was the case on other Snapdragon 800 phones, were they able to activate it?

I'm only aware of few cases where some RF Bands could be activated/deactivated via an engineering menu.
I have never heard of a case when someone successfully hacked modem firmware and added new RF Bands.

Does anybody succeed trying this: http://forum.xda-developers.com/cro...ad-progress-please-leave-im-updating-t2871269 ?
Should work for any Qualcomm based device like Nexus 5.
Thanks for any feedback.

No the program is banned. Besides we already have most the LTE bands on 2 versions. If they could fit them all on they would have done. Maximum 7 LTE bands

Yes indeed there are 2 versions, but I purched my nexus 5 when I was in US and I am now in Europe!

1) never said there wasn't reason for your interest
2) it isn't possible to add European bands to US version. If it was, there would be no need for US version. Limitation on nexus 5 is physical. Maximum 7 bands.
3) the link you provided is for a program that is banned on XDA. You van tell that by reading the thread

Interesting. Can you elaborate on why there might be a "physical" limitation of 7 bands on the Nexus 5? That would be an unusual finding in a recent handset. It's certainly not the case with most current phones e.g. I've enabled dozens of additional bands on my Samsung S5 and others have done the same on various HTC, Sony, LG, etc phones.
If you have any details or a source, that would be appreciated.

Its a limitation of the WTR1605L ref receiver. 7 bands. Actually this was the first (making the msm8974 the first) to be able to do 7. 5 was the previous Max, hence why there used to be a million versions of Samsung galaxy devices

fffft said:
Thank you for the informative reply. You are right of course and I see now where the confusion is arising as well. As you said, the previous max was five bands as in a pentaband phone. And the WTR1605L now supports 7 bands as in a heptband phone. Three bands below 1 Ghz, three bands above and one band at 2.5 Ghz. Bands meaning spectrum frequency segments e.g. 700/800/900/1700/1800/2100/2600 Mhz.
The confusion and this is ironic as well is that 3GPP, the organization who defines the GSM standard also uses the term band to refer to something confusingly different i.e. intra-band segments. And that usage while seemingly ill advised has become ubiquitous. So a band without a context can refer to the contigous 800 Mhz segement. Or half a dozen subsets of it, each of those subsets also being an officially designated 3GPP "band" as well.
When you look at the specs for a given phone, the term bands is often used in the latter sense. For example, the S5 uses the same WTR1605L chip and is obstensibly a 7 band phone as well. And it is indeed limited to 7 "major" bands for lack of a better description. But the specs appear to show the S5 as supporting 16 "bands" i.e. eight LTE "bands", four 3G "bands" and four 2G "bands". And our NV edits can enable dozens more "bands" in the way that carriers refer to them.
Anyway, suffice it to say that rootSU is absolutely correct that the hardware is limited to seven "bands". And at the same time, we can still add dozens of discrete "bands" in the sense that the carriers use the term. Yeah it is confusing.

Yes you can see on the box of the D820, what would appear to be 9 bands, but they all fall within the 7
However, since we have no solid documentation, we cannot still add dozens or even 1 carrier used-term. Its closed source.
Edit > but there is no real benefit to having a d820 and a d821 if they could get everything on the same die.

Has anybody tried to change LTE bands?

hi there, i was wondering, since this phone has MSM8960 which is LTE-capable, and is in fact an LTE phone save for the fact that it is locked to 1900mhz, if it would be possible to "unlock" the radio to be able to use EU/World LTE frequencies.
now, i know that the antenna inside is most likely tuned to 1900mhz so the reception would not be optimal, but still i'm curious cause i found out that there is a tool called QPST service programing from qualcomm that seems to be able to change the radio settings
example link -> http://galaxys4root.com/galaxy-s4-t...aws-bands-on-att-galaxy-s4-sgh-i337sgh-i337m/
so yeah, has anybody tried yet?

I haven't such QPST knowledge, but I believe that QPST can enable the missing bands only if the are listed by the baseband, and then purposely disabled by Motorola when it sells the same phone in different areas.
I'm afraid it's not our case, given the phone is meant for a single market.
I believe that the antennas and filters shouldn't be a big problem, the problem is to have an hacked baseband, which is a task that very few people can do.
That said keep what I wrote with a grain of salt, and see if someone else has better ideas.

this thread is very actual in our time. I would also like to check out LTE for other bands in Verizon phones.
the problem is that topic starter gives link to activate AWS band, it's not LTE, it's WCDMA 1700MHz

It was just an example, I believe.
And BTW would be nice to have the UMTS900 too.
In Italy some small areas are already covered, and starting from January/2014 wil be possible for the Operators to use it nationwide.
I tested it already on during the last summer vacations and is just awesome.
Better coverage than GSM900. with the speed of 3G.

Take a look at page 3 of Atrix HD teardown:
http://www.techinsights.com/uploade...2013/techinsights-motorola-atrix-hd-mb886.pdf
There are not only antenna switches at play, but also band specific power amplifiers.
Besides the hardware parts, I guess that our BP firmware will also be one of the show stoppers for achieving LTE e.g. at 800Mhz on Q.
[Atrix HD is very similar device (we share the same kernel) and we are able to use also its BP firmware to some extent (so the BP signature seems to be the same as on Q).]

Nice find, thanks.
Interestingly enough looks like the Atrix HD doesn't have any ACPM-5005, which is present (for sure) on the Photon Q, (is a band 5 850MHz power amplifier), while the Atrix HD is stated to support that band.
Too bad I cant read the full list of PQ ICs, some of them are unreadable, on the broken logic board I have handy.
For sure there are two ACPM-5002 (band 2/1900Mhz) power amplifiers, and the ACPM-7051, quad band GSM and band 1 & 5 (2100/850) LTE/UMTS/LTE PA
At least looks like the signals are routed differently between the two phones

Aws-3 band 66???

Wind, now Freedom Mobile in Canada has lte frequencies with AWS-3 (band 66). How can I get this on my oneplus one? Can I flash a new modem?

No. The phone doesn't even support Band 2. It will never support new frequencies.

The hardware in the Oneplus one (and 3) does support the new bands, and the antenna required is trhe same as for bands that are already supported, so the only thing that is missing to be able to do this is a firmware update

Ok, but as we've seen for other bands (for example lte band 20) it wasn't enabled over the years, so maybe there's anything hardware-related too?

I think they just don't want to devote the development effort. This is why I wish open source firmware was a thing....

Honestly I dunno if it's a hardware limit or a development "limit". But I've seen a lot of experimental things on OPO thru the years, so maybe I believe that people who can do that exists, but hardware is the real issue.
