[Q] S5 LTE band locking - Sprint Galaxy S 5 Q&A, Help & Troubleshooting

I am a field tech and work with Sprint signal mostly. The S5 will camp on band 41 ( 2.5) not allowing me to see the other 2 LTE bands. Trying to analyse the LTE signal for in building is getting almost impossible since they have not released an amp for 2.5 and in florida thats what i mostly see in metro areas. I am using an S5 and need to know if there is a way to lock the phone onto an LTE band and then unlock it

##data#, edit, enter msl, enable and disable whatever bands you want. At least i believe thatll work

Wow that was easy. The only draw back I see is that band 25 is not in the list only 26 and 41.
No way to turn off 25 to only look at 26
I have a very expensive piece of data collection software XCal Mobile from Accuver ($10,000.00) is expensive to a small company like us that i am evaluating that will allow me to turn on or off every LTE Band not just Sprint. Any clues as to where they are manipulating the phone to make it do that.
Once again thanks for the leap forward in my endeavors. And yes at this point so new to working with the technology and not just the RF i do kinda feel like a doofus

i know theres a way to enable band 25, just cant remember atm.
also, i believe that the lte bands are hardcoded into each device hence why there isnt a LTE hack similar to the 3g prl hack

Dropped Calls!

I may be a minority when it comes to this, but I run my phone unlocked on AT&T. Recently (over the past 6 months or so) I've been experiencing dropped calls a lot where they never used to be a problem. Now, I'm getting dropped calls in my own home as well.
I'm wondering if this has anything to do with it:
http://www.dslreports.com/shownews/ATT-Starts-Pushing-Users-Off-Their-2G-EDGE-Network-118679
My mother recently got a letter from AT&T saying that they would replace her old LG CG180 for a 3G phone. They replaced it for free.
It's no news to me that the 4G Slide will only run on edge through AT&T, but I was just wondering if that would be the actual reason as to why my service has been so terrible lately. I know AT&T has a bad reputation, but it has worked flawlessly for me thus far. I actually switched from T-Mobile to AT&T about 4 years ago, because there was no service where I went to school.
I also wanted to know if there is anything I can do to help the problem. Maybe flash a new radio?
All I know is my aunt uncle cousin and her husband have att ( HTC Inspires ) and they can't make a phone call over 5 minutes without it being dropped. And this has been going on for a year they just won't drop ATT

Yes, dropped calls are really starting to become a problem for me. I called AT&T and they recommended a microcell so at least my signal would be boosted in the house. What I didn't realize was the microcell is only for 3g/4g AT&T phones.
Is there anything I can do to help the situation? I really don't want to give up this phone...
Bump. I don't mind when my threads get ignored but this one is important.
And if I can't find a solution soon, I'll have no choice but to leave this device and go for an AT&T Captivate Glide or Droid 4 (if devs get AT&T 3G going) by this Christmas.
I've been getting a lot more dropped calls recently to the point that my phone is almost no longer a phone. And if the call doesn't drop, it cuts out a lot where I don't understand what the person is saying.
I'm almost positive this is because AT&T's 2G network is being phased out and will be gone by 2017. Unless anyone has a better explanation. Does this mean unlocked T-Mobile phones will no longer work on AT&T after that point?
I got a new sim card from AT&T but it didn't seem to make any difference. Running out of ideas...

Every time I talk to one of my friends who is using an AT&T phone, the calls either get dropped or there is audio dropout. Of course, they have iPhones (and they are rabid Apple fanboys) and blame my "crappy Android", but I only have the problem when talking to them. When I talk to others, even my partner in China, there is no problem. So, I blame AT&T.
Both T-Mobile and AT&T are in the process of phasing out EDGE in order to refarm the frequencies for higher-speed data. While this benefits former AT&T customers who bring their unlocked phones over to T-Mobile, for the few people like you who take a T-Mobile phone over to AT&T, it becomes a big problem. But, that is only for data use. Whether AT&T or T-Mobile, the voice service still runs on standard GSM and those frequencies are still served by both companies. Your Slide uses the 850, 900, 1800, 1900 MHz for GSM service. AT&T serves GSM on the 850 and 1900 MHz bands, T-Mobile serves GSM on the 1700, 1900, and 2100MHz bands, but is now refarming the 1900/2100MHz service to HSPA+. Perhaps AT&T is now repurposing either the 850 or 1900MHz service in your area?

That's most likely possible. I noticed the the 4G Slide only runs on HSDPA 1700 and 2100, neither of which are 3G bands for AT&T.
But the Samsung Relay does support AT&T 3G bands
http://www.gsmarena.com/compare.php3?idPhone1=4914&idPhone2=4018
Does that mean an unlocked Samsung Relay will work on AT&T 3G?

Yes, the Relay would give you voice calls and HSPA+ data on both AT&T and T-Mobile. There are a few other "pentaband" phones (I believe most new Samsung phones are so) that would give you voice and hspa+ on AT&T, T-Mobile, and most other networks around the world.
Note, my MT4GS gave me excellent voice and HSPA+ data while I was in China by using a China Unicom SIM that I purchased at Pudong airport. Before I left the US, I researched, there are two main GSM networks in China (plus a couple of proprietary TD-CDMA) and one of them uses the same frequencies as T-Mobile US, China Unicom.
Ok, so I guess I'm on my own then?
I know my problem is mainly a hardware one and there's only so much I can do. But I'll try whatever I can if anyone has ideas...

Yeah, you really can't confuse the data frequencies with the voice frequencies. T-Mobile and AT&T are always compatible voice/text with every phone. The dropped/broken up voice call issue isn't from incompatible frequencies, it is because of AT&T's crappy network. Data dropouts, however, would be due to frequency issues. If your T-Mobile phone has only EDGE or has HSPA+ for data, that has no bearing on the voice quality.
I'm not too sure about this but try disabling fast dormancy

What is that and how do I do it?
On your build.prop
Enable: ro.ril.fast.dormancy.rule=1
Disable: ro.ril.fast.dormancy.rule=0
Somehow I am having interminent signal lose in our country using mytouch 4g slide. But disabling the fast dormancy did fix the issue.
Before I disabled it I was having 70% to full signal but when using the phone for texting it suddenly drops to no signal. But when I disabled fast dormancy somehow it's stuck at 70% minimum now and never got a signal drop eversince.

If you have to ask, then don't touch it. It is one of the most important configuration files for an Android phone. Make a mistake and it is a real PITA to repair, at least for a newbie who doesn't know what a build.prop is to begin with. Please note, I'm not trying to insult you, just trying to prevent a tragic mistake. That said, you can read many guides on the build.prop and what many of the functions are and there are even build.prop editors that can take some of the hassle out of it.

I downloaded this one

From what I can make of it, each build.prop is more or less a script or a tweak or controlling some part of the phone
I'd be more than happy to try it out, but I'd like a step by step guide. Riyal's commands look simple enough. Just wondering to put what where

That one is good for someone who knows more about it. For a newbie (or even someone who does know more), I would suggest something like this: https://play.google.com/store/apps/...vbS5qcnVtbXkuYXBwcy5idWlsZC5wcm9wLmVkaXRvciJd
It makes adding a new item (like what you want to do) easier. It also has some explanations for common tweaks, and can make a backup for you.
Listen to Fuzi about how important the file is.
When you want to experiment, why not make a copy of it and export to a computer?
You can use notepad++ to browse and edit it, and get to see the whole picture much more clearly then working with it on the device...

In reality all you have to do is add them lines at the end of the build.prop, While it is an important file adding things to it is safe if at the end, removing or changing things are not unless you know what your doing.

Ok, so basically I add a new property?
It's asking me for a property name and property value.
I'm guessing the name can be whatever and the value is ro.ril.fast.dormancy.rule=1 and the other one in a separate entry?
Do I have to write enable and disable in the property value?
Sorry for all the questions, but I tend to be quite inquisitive when I'm treading in unfamiliar waters
Just remember that what you're doing on any computer must eventually be broken down to binary code. Binary code communicates in a series of off & ons and that being the case it already understands that a 0=off & a 1=on. That's my limited understanding of the theory anyway.

Can the LTE band unlocker utility unlock band 12 again?

I've seen this:
http://forum.xda-developers.com/cro...ad-progress-please-leave-im-updating-t2871269
And since we're all pretty sure due to FCC filings that the Moto hardware supports band 12, could anyone tell me itd be possible to open this great budget phone up to t mobiles expanding 700mhz coverage?
Even if you unlock the band, without VoLTE support you wouldn't be able to make calls or send/receive sms messages. This is why Motorola disabled it.
Is that really so important though? Data coverage is all I really need. If there's 2g or 3g fallback texts will still come in, and I think I've gotten texts on lte only mode on my galaxy s4 even on roms that don't support VoLTE or WiFi calling, so texts might still work. Calling can easily be done over Google hangouts as a data call anyway. The coverage is most important to power users, not making it compatible with calls

I'll be driving to Seattle from Chicago next week and I could use all of the additional coverage I can get. I really don't care if I can't get traditional voice / text, hangouts etc are perfectly fine stop gaps. I'm going to buy a Moto G from Best Buy and try this but with no band 12 near me I can't know if it actually is working. If anyone who has coverage in their area wants to give it a shot, I think everyone would love to know if its possible.

If the radio supports band 12, then you can definitely unlock it. Give it a try.

I returned my phone, and that guide seems to be very device specific. Since no one has done it for the Moto G 3rd gen yet, I could easily brick my phone with the only fix as "flash the stock FTF file" which seems to be some special file for sony devices? I'd rather not get in over my head and ruin a brand new device.
Unlock instruction
I found this http://forum.xda-developers.com/showpost.php?p=55475431&postcount=1
But it's for 1st gen
Just so you know.. most of the twin cities area you'd be driving through has band 12 with t-mobile (multiple sources on Google as well as personal experience working at MSP). Band 12 probably wont be deployed anytime soon in rural areas because T-mobile is only using it in urban areas to penetrate buildings with lower frequencies with less line-of-sight areas. What you'd be wanting to look for is T-Mobile refarming their old 2G (EDGE) towers to LTE. Regardless, even with 2G coverage you can still get calls/text/Google Maps to work.
I travel all of North America for work and I'm in a different state every week. I carry a T-Mobile phone as my primary and a Cricket phone (through AT&T) as a backup. I know most people don't have that luxury of carrying two carriers with them, so I keep up to date on this stuff as best I can. People have been getting really mis-informed with this whole T-Mobile Band 12 thing lately.
Another trivial fact.. Minneapolis metro area is one of the best covered metro locations in North America for T-Mobile. Because they bought out VoiceStream, that was one of their top markets. I remember having them when I lived up there years ago!
Anyway, have a safe trip! I'm jealous you're heading to Seattle. Used to live out there as well and I woul do anything to move back! I just got married out there last December.
Hi everybody
Someone check the link shared by lockheed_man in a Moto G (3rd generation)?
Thanks in advance
Anyone with an unlocked band 12?

Regular sms needs a voice signal. If you got a text with only data it was an mms.

Anyone here will jump to Z5/Z5C/Z5P?

Anyone here will jump to Z5/Z5C/Z5P?
Only if it comes to Tmobile..... then again, have to see how the camera is. If it's as good as they say it is, might just have to buy one unlocked.
If you can get an unlocked version that carries all t-mobile bands then I'll probably go with it. Otherwise I'm going nexus.
I think i will.
Finally a fingerprint sensor Xperia which i really wished for. Not sure if i go premium or standard. The standard is a setback on battery life though. But compared to premium im not sure how that will compare. If i can get 2 days on any of those two i will go premium probably. I will wait for review anyways and test it in the store.
Hope they have sorted the SD810 overheat.. It looks like they have done something..

T-Mobile is asking OEM's to disable band 12 support, on non TMO approved phones, which is needed for good indoor reception. This is because VoLTE on 700 has to be certified separately by TMO, and unlocked phones without band 12 VoLTE support can't fall back to 4G when switching from data to cellular leading to no calls but with full signal, this could cause issues in emergencies in areas that only have band 12 (rare issue but could cause legal problems)
I will wait for z6 to buy z5

Thanks for the info. So pretty much any phone t-mobile doesn't officially carry will be unable to get band 12?
I just hope if they do carry it they don't lock down the bootloader. The Z3 is a great phone but I need my AOSP fix. Luckily I still have my old S3 to tinker with.

Now that 3G (USA) is dead, I can't find a SIM card for data (that's all I want) that offers anything better than UMTS. I tried MVNO cards on ATT and T-Mobile, I'm trying Verizon next but it's pretty certain it won't work (SF Bay Area.)
Are there ROMS or any other solution to get 4G DATA in the USA? I don't care if VoLTE / voice works or not.

So to double check, there are no upgrades, ROMS, hacks or any solutions for data? TIA
Looks like tethering is the only option if there is no WiFi. I just changed my phone to Tello w 5GB data for $20, 2GB more than I ever use in a month. (They have great customer and tech support too, light-years ahead of my experience with boost, freedom pop, or red pocket.)

I assume that. US Mobile lets you choose how much data, voice and text you want monthly, starting at $1. I'll keep a very minimal plan going and if I really want data (perhaps where my phone doesn't get it/I can't tether) I can top up. I'm used to having data on my X2 so we'll see, I might drop it.

Yeah, in my area all of that 3G was converted to 5G so unless I travel to upstate NY or certain areas down south I get no service on the X2. I do get 3G in my house because I have one of those T-Mobile CellSpots that gives me service in my house because my area has poor signal on all carriers and the CellSpot still has the old bands but as soon as I leave my house, nothing.
I'm using the US Mobile mvno (TMobile) card and I get "4G" in the status bar, sms without a problem, and for calls, about half go through in and out bound. The other half hit dead air (nothing) or VM without ringing the device. A very low data plan with gobs of talk and text is $8. .... Before today I was rooted and had all sorts of system tweaks, and custom network settings held tight, even after calling. Due to a corrupt system, I did a factory reset today. So I notice it holds at 4G but occasionally goes to 2G (and network settings change itself) after trying a call....
What works is Preferred Network Mode = Global, and turning off automatic carrier select and choosing Tmobile. But it keeps switching back to Automatic carrier selection, and another of many of the network type options. It would be great to get Global to stick but I suppose the SIM has some way to override my settings. Is that something you can do in a custom ROM, block this?

Any way to disable 5G and force to use LTE only?

I had a pretty length discussion with a Verizon rep the other day and opened a ticket in the end. I requested to revert back to 4G LTE from their side, (went through changing my plan down a tier).
I selected LTE/CDMA in settings > connections > mobile networks >network mode = no change in signal and still saw 5G.
Went ahead and downloaded the Samsung band selector app and changed it to use LTE only = no 5G displayed anymore and just see LTE.
After a few hours, i then see 5G signal again and find out that the selection i made in band selector is now on 5G (recommended) again.....
Why?
This is an unlocked note 20 ultra 5G activated w/Verizon.
May be power management, make sure it's not active.
Clear system cache.
Do a network reset and clear sim toolkit data.
Make sure the app is setup right and check it's data/battery settings. Clear data, start again.
Play with it...

Could be that VZW has changed all of the bandwidth in your area to 5G.
I admit, it sounds doubtful this early in the 5G rollout game, just throwing the possibility out there.
A more plausible answer is VZW still has both 4G LTE & 5G active in your area & there's just more "room" available on 5G & using 4G only for the devices that are not 5G compatible, regardless of the settings that you locked-in for 4G.

Not. 5G isn't physically capable of 4G's coverage, it's physically impossible without more cell towers than they can build in many areas. 5G is completely dependent on 4G to fill in all its gaps where it's coverage is limited by distance and obstacles.
In areas that have a large 5G presence it may actually free up more 4G bandwidth.
No, 5G isn't going to make your 4G LTE phone obsolete
This transition is different from earlier cellular generation shifts, which means 4G could be useful a lot longer.

I agree,it's HIGHLY unlikely 5G has totally supplanted 4G in its entirety in any areas yet.
However, it does seem VZW's network management is in play, it would explain why the 4G settings aren't sticking.
I know on T-Mobile, the settings will stick for 4G only........
Regardless, at least the problem isn't lack of coverage. If one is wanting to stick w/4G only,I doubt the difference in battery consumption isn't worth worrying about.

It may be it's not configured correctly. May be the access point information. That's beyond my skillset but Verizon advanced tech support should be able to sort that out! When doubt, just keep calling and escalating the issue.
Works with AT&T... eventually
Crap like this is one of the reasons I just bought another new N10+ 4G. The fast 5G rollout has created many issues not just with carriers but down to the chipsets in the phones and their firmware. I'm giving it a few more years to level out...

Been so long since I had to mess w/editing an APN, totally forgot about that.
After suffering w/Sprint's network & initially waiting for T-Mobile to catch up, I've been fortunate for the past 4-5 years in having decent coverage w/T-Mobile.
I hear ya on the Note 10+, it's still got legs for several more years of use.

You would think the Verizon tech support would have checked that. Sometimes you get a good tech, sometimes you get a do a factory reset dud.
After a year with the S4+ I wanted next year's newest. Not so with the 10+, it's still fun and a solid workhorse. I don't want to deal with R's bs; Q doesn't seem too bad even better than Pie in some respects. At this point I know most of the 10+'s quirks but oddly still exploring some of its many features.
Samsung's offerings this year made the choice even easier, unfortunately. A SD card slot is mandatory, and color rendering is better on the 10+ than the N20U plus that damn R factor, so... it was multiple factors.
Both Android and Samsung shot 2021's line out of the sky for me... a real masterpiece.
Thank you both for the info. So far, LTE has remained after reconfiguring again earlier today. I suspect I'll wake up to 5G and either way, calling VZ to endure another likely waste of my day lol.

You're welcome.
I think you need to dig into Verizon tech support harder and find the right tech to straighten this out.
I'm not sure how the 5G software is structured on the phones as I never had it.
It may be possible to use a package disabler or do a adb edit to kill it's service.
Be aware it may have dependencies; look out for that or the possibly increased battery usage. I prefer a PD over edits because you can use it on the fly with no reboot needed.
