Ok, so i ordered a SM-N910U from 28mobile.com, and they sent me a carrier branded SM-n910K, which by its specifications should work with Brazilian LTE (band 7 - 2600). However I am stuck on 3g. I was wondering if maybe the whole internet is wrong and this device doesnt support this band, or maybe its some sort of carrier lock. Also, how do i disable the awful branding, will flash a different firmware work and which do i flash?
Thanks

So got my new baby, and I love the stock Android UI.
But I got issue connecting to LTE networks here in Germany. A friend of mine bought it in the US store and sent it over to Germany. 3G no problem, but LTE isn't working.
I checked the tech specs, and it says 4G LTE (700, 850, AWS, 1900 MHz). Here in Germany T-Mobile is using Band 3 (1800 Mhz) and Band 20 (800 Mhz) So there is the culprit.
Is this a hardware restriction, or could be solved via software? Maybe flashing a different baseband?
Unfortunatly on the Phone Info screen, you cannot change the GSM/UMTS band. The list is empty. It worked on my Nexus 4 though...
Maybe its possible with a modified modem/radio, dunno it thats correct though and how to do it. There is a radio thread on this forum http://forum.xda-developers.com/showthread.php?t=2192025, check it there.
It might be possible to change the bands using QPST (you won't be able to flash the international modem) there is already a thread on the I337 forums http://forum.xda-developers.com/showthread.php?t=2291589 that has a tutorial for enable AWS bands on the device. The process should be roughly similar assuming the device's hardware can operate at those frequencies.
If it works you will lose north American bands until you rehash the I9505G configuration back.

Wow its been a long time since I've been here! I see all of you are still busy!
... so basically, I'm going to buy an S4, but I'm not sure WHICH I should buy ... and I'm not sure where I should put this question since all the models are spread all over the place, but since I'm in Canada I thought this place would be a good start :laugh:
So basically, from what I've seen, the AT&T (i337) model is quite limited in out-the-box bands, and also has a locked bootloader. From what I've come up with, digging through information about all the models and Canadian carriers, is that the two best models for use in Canada seem to be the I337M and the T-Mobile M919 ... I really wanted a Samsung branded phone, but it seems if I get the I9505 I'll be missing out on a whole bunch of radio bands ... from what I've seen however, the unlocked I337M has no branding on it though ...
So basically what I've come up with is that both the T-Mobile M919 and the Canadian I337M both have unlocked bootloaders ... and they all run on the same GSM freq.
Someone please correct me if I'm wrong here, but, it looks to me like both the M919 and the I337M also share the same LTE bands, which are LTE 700MHz (Band 17) / 850MHz (Band 5) / 1900MHz (Band 2) / 2100MHz (Band 1) / AWS (Band 4) / 2600MHz (Band 7)
(my sources are http://www.samsung.com/us/mobile/cell-phones/SGH-M919ZKATMB-specs and http://www.pdaplaza.ca/products/Samsung-Galaxy-S4-SGH%2dI337M-16GB--Black-Mist,-Unlocked.html - I can't seem to find a reliable source for the LTE bands the I337M has ... on samsungs website it has a * Dependent on market and nobody seems to list straight up specs for the I337M ... actually it lists a completely different set of LTE bands which I'm pretty sure is wrong ... they list 1800 instead of 1700 and 800 instead of 700 which I know is incorrect for Rogers at least)
It looks to me, like the only real difference between the I337M and the M919 is that the M919 has a AWS (1700) 3G radio band, and the I337M has a 900mhz 3G radio band instead of the AWS band ... however, I ALSO have read that the AWS band on the I337M can be enabled (again, correct me if I'm wrong!)
If everything that I have read through is correct, it would seem to me like the I337M would be the 'ultimate' North American model, supporting more frequency bands than any other version (besides maybe the i9505 which lacks some bands I would probably need) ... unless its actually possible to somehow unlock all these bands on every version, and I just didn't get that deep into reading about hacking these phones yet ...
If I got something wrong here please let me know ... I would like to buy one soon and start flashing it
Thanks!
Lets put it an easy way, if I had the choice again, I would have not got the att galaxy s4 us version, I would have got the Canadian S4 i337m. My opinion only.
Or the Google Edition but its going to run you like 700-800$

If you're in Canada why not buy the i337m?
My i337M is completely unbranded once I installed a custom ROM and I managed to enable the AWS. Unlocking it has been a different story though :/
Well ... I just want the phone that has the most bands (its not really a cheap phone!), I'd like to get as much as I can for my money. I honestly have no idea if all the North American models have the same radio hardware or not, but at least on Samsungs website, they list the I337 (AT&T) with many less bands than the T-Mobile M919.
Funny enough, on Rogers website it lists the I337M only having 2100/2600 as the LTE bands, but on Bell/Telus it lits the I337M as having 700MHz/ 850MHz/1900MHz/2100MHz/AWS/2600MHz
It seems silly to me to actually manufacture different radio hardware for all the different North American models ... considering they almost all use the same bands except some exclude some, and there is one different one (3G AWS on M919 vs 900Mhz 3G on I337M)
I wouldn't get the AT&T US version ... as far as I know nobody has been able to unlock the bootloader. But apparently the M919 isn't locked.
I considered the Google Edition, but as someone said, it will run 700-800 (and you can't 'officially' get it in Canada)
Anyways, I found an unlocked I337M and I believe it is also unbranded ... so I bought it. If its not, I'll just flash it
I still am curious as to what they actually do with the radios though ... if they actually use different hardware or just lock the bands in the firmware (I'll take a guess the international I9505 actually has different hardware, though)
I think it would cost Samsung more to design different radio hardware for all the different North American providers (considering they almost all run the same/lots of overlapping bands) than just putting firmware locks?

I337m has all the radio bands, handles the lowest CPU voltages while still being stable... has an unlocked bootloader, and simply kicks butt.
Simple modem firmware flash fixes any location specific, and in my case, non-existant radio band issue.

Hello geniuses!
Before anyone asks, I have already tried the search function and was unable to get any pertinent results!!
I have a n9005 unbranded factory unlocked phone that I purchased through a retailer in Singapore. I absolutely love this phone it is such a beast!
However, I am having a problem with the handset. I am with telus up here in Canada and I am unable to connect to their LTE network. I called customer service to ensure that LTE is enabled on my plan and it is. I am getting HSPA+ speeds and I am able to make voice calls just fine, but I bought this phone thinking I would have LTE enabled on it.
Now from my understanding, the snapdragon 800 chipset has LTE bands that support numerous networks. However, since this is a phone from Singapore it may only have Singapore LTE bands enabled. Is there a way to change it so that it recognizes Canadian bands, more specifically Telus' LTE network?
I read that by flashing a new modem or csc I would be able to get LTE speeds, is this the case? If so, can some one guide me in the right direction on how to do this as I am a complete noob!
Thanks everyone!:fingers-crossed:
Did I not just answer a similar thread about someone with the *exact* same issue with a handset from Hong Kong?
Singapore uses the 1800 and 2600 LTE bands, Telus only the 1700 band. You're using a phone that doesn't even see your LTE band...

Yes - wrong phone for Canada. You need an N900W8

Yes I understand that...
That's why I asked if it's possible to flash a different modem on the phone that will enable the 1700 band?

Does anyonr knows how to flash firmware or modem then I will be able to activate lte on my note 3
Thank you
if u havea 4g enabled device such as note 3 model number n9005 then u can use 4g untill its frequency is not supported.... the supported frequencies are not software based.. the are hardware based andcannot be changed.... note 3 n9005 supports LTE 800 / 850 / 900 / 1800 / 2100 / 2600 and note3 n900w8 supports LTE 700 / 1900 / 2100 ... if ur carrier transmits on frequency other than these then us device is useless.... many people buy these devices only because it has 4g but they arenot even aware of supported frequencies so u all must research properly before buying.... PLY PRESS THANKS IF MY POST HELPED U...:fingers-crossed::fingers-crossed:
hi all, I have just purchased the awesome oneplus 2 locally BUT didn't realise that it is the Chinese model until i got home.
Unfortunately I am with Vodafone UK and 4G doesn't seem to work, so i was hoping someone had an idea on what i can do with regards to this?
Would flashing a radio help? Thanks in advance

Vodafone UK uses Band 20 & Band 7 for LTE & the Chinese OP2 (A2001) only has Bands 1, 3 & 7 enabled.
So, if you're not in a Band 7 area (very limited ATM), you won't be able to use LTE.
Flashing a radio won't help as the three different models have different bands enabled in hardware.
Only the European/Asian version (A2003) has Band 20 enabled.
Ref:
EU/Asia (A2003)
LTE: Bands 1/3/5/7/8/20
North America (A2005)
LTE: Bands 1/2/4/5/7/8/12/17
China (A2001)
LTE: 1/3/7
ah ok thanks for the reply mate I appreciate it, looks like im either stuck with the device on 3G until band 7 is rolled out or see if anyone local wants to swap ha
Hello to all,
I have a ZenFone 2 Laser (ZE500KL). Asus support said me that is a Taiwanese version.
The issue is that is not working with LTE network in my country, only with 2G and 3G. Here is used AWS1 that is the same AWS band 4 (1700/2100 MHz) 1700 for uplink and 2100 for downlink. Asus support said me that I have nothing to do since is a hardware issue because the antenna doesn't work in 1700/2100.
Is there a way to know if this handset could be enabled to work with LTE AWS Band 4?
Thanks in advance for any help.
Regards
First thing first, I'm sorry if my reply did not help you, and this is based on my limited understanding...
Simple answers would be nothing, nothing you can do if this is "hardware" limitation as asus told you.
Now the explanation, note that I'm not knowledgeable about this thing, so I don't think could give a meaningful explanation.
From what I've read, LTE, on different country use different band (1700, 2100, etc). And by that, just say *not the real reason, just play along with it*, "device built by limiting hw capabilities to certain band, to work on region A, because that device didn't meant to work/used outside region A" . This might the reason, you could see asus with WW or TW variant. They limit the device hardware to work only with certain band range.
This is hardware, not software/firmware (if you compare it to like some "unlocked provider device") . So you can't do anything about it.
This is like, using CDMA phone with GSM card, they work at different band. AFAIK it didn't work, cmiiw.
Oh, IIRC, old phone (before Android born) mostly have triband (GSM) you might won't be able to use your device outside your country. Then, newer phone, till now, use quad band to support usability around the globe. cmiiw
I hope you get what I'm trying to say there~
I don't know what it mean about LTE aws 1 / aws 4, I don't think this is just band length (1700/2100).
