I have a NOTE 4 with T-Mobile, other that, some software and radio frequencies being different really the radios are all same. just software based on which frequencies are to be used by which carrier or are the 4 all different and in what way hardware wise?
Just curious

what do you think will happen? will I get the ability to use band 4 and 17 for optimal at&t lte usage? right now i get intermittent lte with my c6903 in miami. I tried to flash just the baseband of the c6906 firmware and it took like 3 seconds and nothing really changed. while I do speedtests with friends next to me with their at&t branded phones their lte is just faster then mine most of the time. what do you think?
Bands 4 and 17 require specific hardware that is only available in the c6906. So no, you cannot flash a c6906 ftf on your c6903 and expect bands 4 and 17 to work. Your friends might be getting better cell reception as compared to you but.your speeds should be pretty much same.

Hi guys,
Can anyone confirm with certainty wether the XT1052 (Europe) shares the exact same hardware as the rest of the models released?
Looking at GSM Arena's specs for the various models, all I can see a difference in is the 4G LTE frequencies at which they operate are slightly different.
Is that due to different radio hardware or is it a software modification that enables/disables specific frequencies?
Any replies very much appreciated.

We have attempted to enable bands (in NVRAM) that aren't available on some models....it didn't work. I think its safe to say that the radio hardware differs between the different models.
I will be taking my verizon XT1060 DE phone to the UK in a couple of weeks. Last time I was there I picked up a gifgaf card but didn't have time to focus on trying to use data. This time, I'd like to be able to use LTE data but most, if not all, carriers in the UK use band 3 and 20. I believe the xt1060 has bands 4 and 13 enabled. Is there any way to enable the UK bands on the phone?
Unfortunately, no. It's a hardware limitation.

Per FCC approval, the verizon version has hardware for lte bands 2/4/7/13 - Verizon
The current XT1060 rom/radio files only supports LTE Bands 4 and 13.
I have seen nothing on enabling other bands, nor have I seen the rom/radio files from other modes which are compatible to flash in order to enable any other LTE bands.
i.e. No matter what the hardware is capable of supporting, as it stands today, you are stuck with LTE Bands 4 and 13 only on the XT1060.

just to make this clear:
does the vzw xt1060 has hardware limitations for band 7 or not?
if i flash e.g. the rogers or at&t radios i will result in a phone with imei = 0 until flashing back to the vzw radios?
is the cdma&"worldphone" chipset responsible for this?
thanks in advance
You can't enable bands that aren't supported. That's it. ?
Hi All,
I am on Vodafone who don't use the Band 20 frequency for 4g.
I have the Note 920i version, I have now found out it doesn't work on vodafone 4g as the phone doesn't support that frequency.
I assume there is no way around it?
Thanks
Someone mentioned chamging in service menu but also that could not work
http://forum.xda-developers.com/showthread.php?t=3182455
main networks that use B20 in the UK are o2 and vodafone I think, EE and Three also have a little spectrum at 800Mhz not sure how much its deployed, I think I read that EE was using 800Mhz in rural areas because they could not support alot of handsets on it at the same time due to the limited spectrum/bandwidth that they have. A pity since the 800Mhz frequency is the one which travels through buildings better.
So is the US t-mobile variant SM-N920T the only one with B20 ? What chance is there in unlocking a phone bought off ebay? From what I gather T-Mobile handsets can only be unlocked by T-mobile and not other online services. On the Note 4 it was known that you could flash another carriers firmware on it and then unlock using one of the web services.
I am from slovenia I am waiting for note 5 N920I and we will see how it works now I had 915s note edge Korea version and I didn't have any problem and it was missing band 20...

But did it connect to Band 20? maybe your older phone just used different band that your network supports
I have the Korean N950N and I would like to try flashing the N950F firmware. My N950N seems to have issues switching between HSPA+ and LTE/LTE+ to the point where sometimes I'll have zero LTE bars, and I get no data, but if I switch to 3G only, I'll have no problems and full bars. I don't think it's the CSC so I'm guessing the N firmware handles the wireless frequencies differently, even though it shouldn't. What's also weird is my G935F (S7e) always has at least one LTE bar when testing from locations where I get zero bars on the Note 8.
How do I create a TWRP flashable firmware package to change the model number/firmware and test that variable? I already know I can't flash with ODIN because the signatures won't match. Also, is there anything else that may be causing this issue? My S7e should *not* be getting better reception than my Note 8, based on everything I've been reading about improved modems.
You might want to check the supported frequency bands of the Korean note 8 and the band your carrier uses. Might be a hardware problem and cannot be solved by playing with software.

The N950F and N950N have literally the same hardware. They support all the same frequencies and have everything I need to connect to AT&Ts network. The only difference is the Korean N950N doesn't have the region lock and "jail" issues of the N950F. Additionally, I am able to get full LTE-A bars and speed in other areas and have no issues.
My problem is at my home I, at most, have one bar of LTE-A coverage. Sometimes that coverage drops to zero bars, and there isn't a switch to HSPA+/3G so I have issues sending texts and accessing mobile data until I either shift the phone and get a bar, or completely disable LTE and use HSPA+/3G exclusively.
Automatic switching between LTE and 3G is the issue, not support for the frequencies themselves.
EDIT: In addition, my SM-935F (S7 Edge) *never* loses LTE reception in the same areas and has never had this problem.
Some providers operate on two lte frequency bands. Perhaps one is supported the other isn't.
Most n950f doesn't have region locking.

Actually, almost all of them are region locked if you're buying for use in the US. And again: the supported frequencies aren't the issue. Even if they *weren't* supported, I should be switched to 3G when there's no LTE reception, which isn't happening. I just get zero LTE bars and no data instead of switching to 3G and slower data.
Additionally, the same exact frequencies are supported by my G935F (S7e) and it doesn't have that issue.
Aah.. american telco.. there is a reason they aren't selling n950f there but the sd variant.
And yes it's the frequency. I saw it somewhere but i can't recall.
Which telco are you on if you don't mind me asking

Yeah, the reason we have Snapdragon is some US Carriers use the CDMA network technology and It's easier to just use Snapdragons + their built in modem as opposed to gluing the Qualcomm modem in with Exynos (which was done only once with the S6 and Note 5 because the SD 810 was so ****ty). Either way, they'd have to pay royalties to Qualcomm for CDMA technology usage. But that's neither here nor there for my situation.
I'm on AT&T. It's a GSM based network and fully compatible. I literally have stated multiple times that I the phone supports all frequencies I need. I have the SM-N935F (S7e) which supports the *exact same frequencies* and I do not have the issue with that phone. My problem is handoff to 3G when there isn't good 4G coverage! It *never* hands off to 3G unless I've got a call active. If I have low reception, I'll just have zero 4G bars instead of switching to 3G. If I manually disable 4G I have full 3G reception. When I go elsewhere with better reception, 3G handoff is irrelevant because 4G is working with full speed.
Just to prove my point: Here is the frequency compatibility table for my International S7 Edge:
https://www.frequencycheck.com/carr...-edge-lte-a-samsung-hero-2/at-t-united-states
Here is the compatibility table for my Korean Note 8
https://www.frequencycheck.com/carr...d-lte-256gb-samsung-baikal/at-t-united-states
All the frequencies, minus one LTE frequency, is supported on both phones. My issue is I have *better* speeds/reception on my s7e and when I have low bars, it actually hands off to 3G where my Note 8 doesn't. AT&T is a fully GSM based network and compatible with the International Samsung phones. I've been buying them for years.
Frequency support is not the issue. If it was, I wouldn't get any 4G reception at all! I'd have to use 3G 100% of the time. I need to solve the 3G handoff issue when there's low/no 4G reception.
