Hey guys and gals I was dabbling around and got curious and used the S4 Dialer Codes from that forum and they also (most of them) work on the Gear S, so maybe we can also try and tweak these little device's from the service menus like our phones, see my screenie for proof, I used *#0011# and also tried *#197328640# and it works too, I don't know a whole lot about the functions within these menus and I know that if you mess around in there you can really screw up your device so TRY AT YOUR OWN RISK I AM NOT RESPONSIBLE IF YOU BRICK OR DAMAGE YOUR DEVICE!..I just wanted to point this out since I didn't see any threads or topic about this yet and maybe a DEV can jump in to provide some guidance as to the functions within these service menus.
S4 Dialer codes forum.

Ok just browsing through the menus and if you select [4] Reserved just look what's in there! and although this is the only setting that would not enable does this mean it is possible to enable it via software? Could LTE be built in awaiting another software enabling update like other sammy devices? that would be pretty slick! an LTE Smart Watch!
doesnt the t mobile version already have LTE? Thats how they are advertising it..
No, none of the Gear S has LTE. Don't confuse '(fake)4G' with LTE.
wow, shocked that a mobile company would engage in deceptive advertising! :cyclops:
actually, its a non issue, considering how little actual data use most will be using with a smart watch at this point..

From what I can see the only symbol that pops up on my t-mobile Gear S is 4G, but my question is why would LTE band selection be inactive within the service menus, none of the previous gear watches had LTE so why would it be in there? And its funny how selection 4 says reserved where the LTE selection is.

The LTE is likely showing because it has a Qualcomm Snapdragon 400 chip in it. That chipset supports LTE as well as dual mode GSM/CDMA (e.g., the same watch would work on Verizon as well as AT&T), as well as quad-band GSM (850/900/1800/1900), but that doesn't mean the radios are actually in it.
That menu is very likely a holdover from the S400 operator menus in other devices. Manufacturers tend to be lazy when it comes to modding things like that.
Of course, until there is a teardown we don't really know what all is inside this watch. Also, the previous Gears didn't have the same service menus because they don't have chipsets that support independent cellular radios.

I asked iFixIt and they say they are too busy ... which is shocking to me given what's inside of this watch ... Somehow the Kindle Voyage is more important to them ... HAH.
I don't know what the deal is but the media is REALLY resistant to the Gear S. And I don't like that at all.

Surprisingly the user manual from the UK site HAS disassembly instructions in the last few pages.
Ostensibly this was for replacement of the battery......
Doesn't seem very difficult. Remove the screen, and everything else is right underneath.

Ok, just a disclaimer (I am well-aware of my n00b status here)... I spent quite a few hours already on this site and on the Android forums, and on Google searching for answers to this... Not to mention time at the AT&T store and chatting w/some other phone reps (including Samsung tech support and AT&T tech support)... And while I've made some progress, I still can't get any definitive answers here.
So... that being said, first (and big 'sigh' I'm sure to many) is that I'm using a South Korea Note - the SHV-E160S. I know this is the I717 forums, but before I get flamed and booted, let me explain...
Well, I am on AT&T. No problems with calls or texting (minus the annoying 80-character limit, but anyways)... However, I have a BIG problem with the LTE. I'm on the LTE data plan, however, I cannot access any data network other than GPRS. Yes, my pings take about 533ms. My download speeds are about 53kb/s. This sucks, quite a lot. Esp when compared to my fiance's Note, which side-by-side gets about 13mb/s on the LTE network.
So... Did some research, and got the run-around... Less all the crap I heard from AT&T reps... It seems that the antenna for my Note is set to LTE850/LTE1800, and the actual AT&T SGH-I717's antenna is set to LTE700/LTE1700/2100. My sources for this come from PDAdb.net (I'd hyperlink, but my post count is not high enough to do that, yet).
So... Here come the questions. First... Is the antenna frequency tuning something built-into the hardware, or is it something that can be tuned via software?
-If it's in the hardware, would it be possible to buy an AT&T-spec LTE antenna? Which antenna gets replaced (from what I understand, there are two, and I can't find a legit source that tells me which is which), and where could I buy such a thing?
-If it's in the software, what would I have to do to re-tune the antenna? My phone is rooted with the latest Gingerbread Tegrak kernel.
Lastly... Though there is a difference between the LTE antennas... I still cannot access any network other than GPRS. I should at least be able to access EDGE, UMTS, HSDPA, HSUPA and HSPA+ as well, but I can't.
If ALL else fails, I guess I could get a portable tethering device with a contract... But that'd be oh-so-annoying to have to carry around all the time, and I'd like to avoid that option as much as possible. I'm paying $30/mo for LTE service on my phone already!
Anyways... Any thoughts or advice would be very appreciated, and my apologies if anything here is out-of-place. Thanks in advance!
U have the international note. Doesn't have late chip in it. But ur note has better CPU then the att note. The international note CPU is not comparable with att lte chipset that's y Samsung use 2different CPU. Yes u should be able to get 3g. Reset your apn. And search around. To find the code to reset your apn. I forgot. Its something like *2260*
I had an international first, had to rest everything to get data. But after few days. I return it cos I prefer to have lte speed more then CPU speed. And I found out the u can just over clock att note to 1.85 instead of stock 1.5. So now I am very happy with my att note.

Hmm I'm not sure if this method works with the International Note but it's worth a try. You need to get into ServiceMode. On your phone dialer keypad type *#2263# and choose 2 WCDMA Band Preference and select (6) WCDMA all.

Thanks for the tip, but all I get is an error: "Connection problem or invalid MMI code."

Maybe the issue is your kernal and/or radio? Isn't the Tegrak kernal Korean? Most likely your radio is also. That is probably your issue. The way I see it you have 3 choices: Live with it, Sell it and buy an I717 variant, Take the risk and at least flash the ATT Gingerbread radio.

Do all your entries match these? Write down your current ones before changing or take screen shots. You must use the menu key and save changes. Also make sure that is the APN checked after rebooting.

he doesn't have the international note(n7000) he has the South Korea Note - the SHV-E160S (he says it in OP), which it has the same processor as ours but some minor diferences in other things.
To the OP, why do you have a korean Note when from your avatar you're in the US?, I'm sure there's your problem, that note is set to use bands in korea and not in US, so the data is going to be crap, and for you to attempt to swap out the antenna is risking braking the phone because you run a chance after swapping it, not working and not having a working phone anymore.

I matched the APN settings of my fiancee's LTE Note first, and that did not work... It's pretty much exactly what you have posted. However, there are a couple things of note (bad pun, sorry). I do not have a 'APN enable/disable' or 'Bearer' field... However, everything else is set the same.

I have a Korean Note because I was living in Korea for a while, and I just got back to the US last week.
As in my OP, I found that the LTE bands are different; however, I can't even get on any other data networks other than GPRS. I've tried some APNs for HSPA+, and the results are the same.
Swapping the antennas shouldn't be THAT big of a deal if I had to... I'm pretty mechanically inclined. Obviously, I need to know if it would provide the intended results or not first.

Can you even do that when it's locked? I'm just wondering about the remote possibility that all the NA versions are the same hardware but AT&T just says that theirs is quadband.

I asked a Bellevue Square Microsoft Store employee in Bellevue, Washington. He said the 920 is pentaband. I asked him if it would work on T-Mobile and he said "Theoretically." Obviously the phone is still locked...
To be honest with you, I don't believe him 100%. It may be pentaband capable, but locked to quadband.

Total guess here, but I seriously doubt that these 920's for different carriers are going to be limited at the hardware level. I imagine the most cost efficient method for making these things is using a single design, same chips all around. Then, you lock it down via software.
I am sooo tempted to get one of these, but I refuse to buy from AT&T if they're going to hold me hostage. If the unlock is withheld during the exclusivity period, maaybe I can see that... but if they won't do it after that, I would be seriously pissed. I am on Tmo now, and it makes more sense for me to get the 8x Global phone ATM.

Obnoxious carrier branding is really unsightly. I seriously hope Telstra does not do this in my country.

Really seems like there is only one flavour of the 920 and it is pentaband.

It's more difficult for you guys in the US because TMobile has old frequencies that will still be detected by the phone (ie. 2G). It's easier here in Canada because Wind has no fallback frequencies outside of the AWS spectrum. Basically, if you go into the manual network selection screen and see Wind you know the phone supports AWS.

Doesn't WP8 show anywhere the connection speed like E for Edge or 3G?
Well I can confirm that it works with 3g speeds on t-mobile except it's shotty... my phone will go to E randomly and the only way to fix it is to go to settings for cellular and switch data speed options. Which is lame. The phone is defective anyway cause the headphone jack doesnt always work so it's going back.
Wish I didn't pay for next day saturday delivery. Annoying.

Maybe you're in an area where T-Mo is refarming their bands to include 1900 MHz? That could explain spotty 3G, even if the phone doesn't have the 1700 MHz band enabled.
We're you using a T-Mobile SIM or roaming or what?
Did you unlock to try on T-mobile US? I am with everyone here that I want to to stay with T-mobile's lower rate, but really want the 920.

Nokia lists the supported frequencies on the box, I would check that first to see if it's even listed as pentaband.
Does anyone out there have the IMAN i3 from China working with AT&T? We were able to get the phone working with voice/text with no issues, but the data will not flow. Not really sure what the problem is. We've tried manually programming the APN to get it to work and it doesn't seem to help. Any advice would be great. Even if it's an APN you know works. Thanks guys!
According to the specs of the phone, it will not get 3G here in the US. It is odd that Edge isn't working though. I'm assuming you did make sure that data is enabled? (sorry, but it's been known to happen...) The tricky thing is that there are a handful of different APN configurations out there and some work better on certain devices and/or updates than others and maybe even location dependent for some.

Yeah, data was enabled. I even swapped out with a T-Mobile SIM, which at least get Edge service, and it worked. I tried a few different APN configurations and it finally at least got Edge. That sucks we can't get 3G though. I take it that this is going to be the case for most phones coming out of China?

True, but there are plenty of Chinese companies that have expanded their offerings to include phones that can get HSPA here.
OP: When you are searching for phones, the main thing you need to check for for data compatibility is that the phone uses the 1900 Mhz freq for WCDMA or HSPA. Pretty much every phone will say that it uses 1900, but you have to check to see if it is only listed for 1900 under GSM (which will be the 2g or Edge data) or if it's listed there and for 3g/WCDMA/HSPA/UMTS (these are often used interchangeably on many sites).
Take for instance, the lineup of phones from the company BLU (they rebadge some Chinese phones to sell in North and South America and add a few of their own touches). They have 2 series for each line of phones - one ending in "i" and one in "a". Same phone, just have different data bands enabled. "i" is for International and "a" is sold in the States and gets our type of 3g.

Hi friend! do u have stock firmware? I need very much!
I have a dreaded Verizon. For the time being, I really only need to alter the radios to tune for Tmobile frequencies. No one seems to advertise or understand this but since the S4 is fully capable of nearly every frequency world wide, and I get next to no signal when on T mobile, I believe Verizon purposely only turned on frequencies that they use.
So, unless someone else has a slick work around for the time being, I will have to figure out a root procedure for this configuration. I looked at this late last year and seemed to be a big hurdle.
King root seems to be inconsistent. What are my options for this?

the only way it could work is that if you had a i545 running a MDK which lets you run custom kernels
as of now there is no way to flash non-verizon modems to the device
Mobile Networks> Network Mode>
select UTS/GSM is about all you can do
verizon even remove the service menu that shows the available bands
Wow, Verizon must have done their homework on locking down phones. That boot loader is hosery. I consider this much like the government forcing them to give the keys, but did not say they had to put air in the tires. Without the ability to run or select alternate frequencies, service is a no-go
I am mostly in desktop computers but curious why these phones are not being wipes and reloaded with a new OS from scratch? Why all the work arounds and hacks? What am I missing? Does Android have all this on lock down?

S4 Is a terrible device you would be better off with something like a huawei honor or moto g or moto X
I am curious about your phone selections. My basic needs are only a high end device with good signal, mic, speaker, display, battery life, and memory capacity. However, I really felt I MUST have a phone with SD card ability but I really don't remove it, I don't take many pictures, and probably don't need that feature.
What I DON'T want is a device that is HUGE. I like the size of the S4. T mobile felt sorry for my phone issues and gave me an LG Leon. I simply hate it.
I should mention that I later intend to consider writing some custom apps for basic wifi and blue tooth functions so I want a playground that affords me some latitude.

Thank you! I find phone shopping to be rather daunting. I see a lot of developers using the Nexus product but also see a lot of people using Samsung due to all their included gadgets on board.
One thing that may be handy is the IR emitter. Is there a site that compares different products well? I do notice the honor does not get high marks for their display performance.
As well, due to using T mobile, I am unsure on compatibility. I need to know if the boot loader is responsible for toggling certain bands on/off? If I buy an honor for ATT, I assume it will be toggled for ATT frequencies? Since the BL is unlocked, can I toggle other bands to ensure I get the best service possible?

idk why you said the honor doesn't get high marks 1080p ips is pretty dam good
tho I guess some `review sites`
having a 2 or 4k display on your phone does no good if the gpu can't drive it
it will look real pretty but real world performance will suffer
different phones vs different carriers e.g CDMA phone like the i545 verizon s4 can not be used on GSM carriers such as ATT and Tmobile
read here for more info on that http://www.pcmag.com/article2/0,2817,2407896,00.asp
a unlocked bootloader grants you the ability to run custom roms and flash certain portions of the phone that are normally inaccessible
the bootloader has nothing todo with radio bands
the honor or any other factory unlocked phone should work on your carrier without issue
Thank you! I guess my only real requirement in the display is having one I can actually see outdoors! Amazing how poor the screen is on this old LG leon.
Maybe you can help me better understand how the bands are configured and/or locked on a phone? The reason I ask is the Verizon Galaxy S4 is technically capable of all bands that Tmobile uses yet I see poor functionality with it, indicating tome it is not picking up certain frequencies. I made the assumption the boot loader would be isolating the bands? Is this software controlled? Or not at all? Which would leave me wondering.
For reference, the Verizon S4 DOES work on Tmobile though. It holds 4GLTE signal but texts will not go out because I believe Tmobile is using 2G or 3G for that.
The way I assumed this worked is the phone is capable of a WIDE range of bands and frequencies, but the service provider would invoke only certain frequencies that they use?

if its holding lte then all you need todo is change the APN to point to t-mobiles servers (store should have offered todo this for you)
t mobile uses slightly differing frequencies depending on your area you are lucky enough to be in one of the area's that use the higher bands
instructions are here https://support.t-mobile.com/docs/DOC-2090
this will not change the fact that you may or may not get data signal depending on where you are connecting too
I would install textra from the playstore and set it as your mms app it has some over-rides for the apn settings if it won't let you change it via the system UI
alt instructions use the`fast` for lte

Right now the S4 indicated locked to 4GLTE but signal is -90dbm, 50asu. I tested data and I am able to use it though it is slow. I, however, still cannot send an sms. I am able to edit settings for the APN but have verified all settings are per tmobile specs. Any ideas where to go from here?
In the network modes, I am able to chose, 1) global, 2)LTE/CDMA 3) LTE/GSM/UMTS
I have it on LTE/GSM/UMTS right now. IIRC, the GSM is the 2G/3G for sms and voice?
Is it possible that the I545 is trying to operate on the Verizon 750mhz instead of the 700mhz of Tmobile?

should tell you what band its connecting on
install textra and go into its options and enable the 't mobile fix'
OK, I loaded Textra and LTE recovery. I honestly am not certain of what I am looking at on the LTE app but looks like I am connecting to band 4 LTE. At that time, I could not and still cannot send a text. However, at some point, it switched over to a UMTS connection and I was able to fire off texts normally so I know my APN settings are right and there is something odd going on. Textra did nothing different and there is no setting for tmobile other than a wifi setting.
I have read many other people having this exact problem which hovers around those using a verizon S4 on tmobile and upgrading to 5.0 OS.
What I need to figure out, and maybe an area that would require another thread but I need to learn if I may need to reflash the modem to function properly on tmobile and if that can even be considered on an unrooted, boot loader phone? If not, what are the best options? Just dump the phone and get something else? I read of a few roots on the OC1 platform but not sure on that.
If I knew my efforts would work and I knew what I needed to do to fix this issue, I would. I almost just upgraded to the latest revision hoping for a patch in there but not sure I should do that if I want to root? Is OC1 and above all the same for rooting issues?
you don't even have to root to work around this. you can downgrade modem to MDK build. Then use QPST/QXDM to change item 6828 to value 4096
Sins07, I am very interested in the modem mods you suggest as I also came to the conclusion the modem is the issue.
Would I out of line to ask if you can dumb this down a little for a newbie? You mention downgrading the modem only and was not aware you could do that. Can you explain how this modem issue is occuring and how the modem mods will fix it?
1. Does Black Shark 3 Pro support HDMI out via usb-c?
2. Does it support volte in the USA at all?
Would appreciate answers as I'm considering this device but can't find answers to these two questions anywhere.
It supports HDMI to type C and they have an official cable for that..
Check the frequencies supported by the unit you will be buying.. For reference, check GSM arena for that

Thanks.
I know it supports the correct LTE frequencies, but I've had Chinese phones before that didn't get volte.
To be fair, I use cricket because I don't care much about data speeds, and maybe they only allow specific phones to get volte. I just want to make sure I don't buy and then have a useless phone by next year.
Thanks for the reply!

Volte works in US. It is missing some bands though. I dont get great service in some areas.

Thanks man, think I'm going to get it. Global version I'm looking at has every band I need, and I kind of want the massive screen more than the ROG3's superior specs.

Yes, cricket(ATT) you should have all bands. You might have an issue with volte though. ATT...errr cricket a real PITA with getting volte. I love the phone, other than missing some key tmo bands

Am actually going to move to mint I think, the volte thing has been annoying me for awhile. Are you missing bands for tmobile because you have the Chinese version? Because I checked the global and it has 2, 4, and 17 which appear to be the main ones.
Do you mind if I ask your personal opinion on the battery life? You seem like you've had it awhile ?

Batt life is insane. On mint you will be missing b 66 and 71. Same as tmo. I do at times, especially mediocre areas, have no signal, while my wifes phone has a signal. I guess i will deal with it. Overall i love the phone.
