Hi,
Just wondering if this device has the ability to unlock the 850mhz band through the hardware menu like many of the other Samsung devices?
Im currently after a device that runs UMTS/WCDMA 850mhz and LTE1800mhz bands.
Thanks for any help
Look here. All the supported bands are listed

thanks for your reply. I have seen all those spec sheets on gsmarena and phonearena many times before.
However, I just realised this isnt the phone i was meant to aim the question at lol. I was looking for the Samsung Galaxy S 2 HD LTE phone forum. My mistake, please remove if required.
thanks.
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.

nah, it should be just a matter of chaning the right NV settings to the appropriate values. that's the hard part basically, cause there are a ton and it's not immediate to locate them
i mean that biggest problem is antena switch

Still a guess, but I blieve that hardly the switch would be a problem, if properly driven.
Btw a definite answer to this question should come identifying the switch IC and checking its datasheet.
Do you know what IC is doing that function in our Phone ?

if i dont forgot i can check it tomorrow
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).]

it was just an example so show that it is actually possible to unlock frequencies the phone was not meant to work with

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
I was wondering if anyone has had any luck with definitively determining which network bands are offered on the SM-G920W8. I have done a lot of searching today, and everything I seem to read online about this is conflicting. Is there a source out there with this information that someone thinks might be correct?
I am mostly just wondering if my phone will be able to access European networks while traveling.
A related question - if I key in *#2263#, select Band Selection>LTE, I get a listing of LTE bands. Are all of these active on my phone?
I can post screenshots if it helps.
Hi,
I'm new to posting on xda, been using it for advice for ages but this is the first time I haven't been able to find my answer. So I'm going to apologize if I've posted this in the wrong place or done anything else incorrectly right now.
I ordered an R7 plus from Taiwan and received it a few days ago. A great phone, i am entirely in love with it. I can put up with the bits of scattered chinese in the settings as i will be flashing cyanogen as soon as it's available. My problem however lies in the connectivity. I didnt know a whole lot about wireless data before ordering the phone, but what little I did know I applied to my research and found that all three variants of the phone should work on my providers network. I have the Taiwanese variant, which does supposedly support the 2100mhz, and 2600mhz frequencies, which i believe are bands 4 and 7, anyway, these two frequencies are the frequencies my provider uses. Rogers uses FDD with 2100 being up and 2600 being down. Yet in the phone settings when selecting which LTE band 4 and 7 arent options, there's USA Band (Im unsure what this really is, I assumed it was 4 because much of the us uses band 4), 6, 33, etc. And I havent been able to get LTE to work. The APN is configured correctly. All anyone's been able to tell me is that it should work. I can provide any more information you guys need, but any help would be greatly appreciated.
Edit: For more info- My provider is Rogers, i have also tried it on Bell (still only 3g), and Wind, which works the majority of Chinese phones and it didnt even pick up their network. Any advice would be great!
Hello everyone. As many of us first posters here, I have a problem:
I've bought an north american J327U from someone I know, and that person only used it at home with their wi-fi. It's got an Exynos chipset, and no support for the LTE bands from where I live in (which are completely different from the USA's LTE bands).
After quite a bit of research, I found here and elsewhere methods to change LTE support for Qualcomm devices, but had no luck finding any for Exynos devices. Is there any way to do the same thing for devices with Exynos chipset, or am I stuck with no LTE? I also know it deppends on the hardware support for that, in my case I would need support for bands 3 (1800mhz), 7 (2600mhz) and 28 (700mhz). The phone covers none of those.
My device is not yet rooted, but I'm fine with doing so if needed.
Thanks in advance for any help.
I don't think you can physically change the bands unfortunately.
