I couldn't find this info anywhere on xda but I wanted to share this with you all, as the xda community has always helped me and I've rarely had the opportunity to return the favor.
I'm a month into a new G3, and all was well until the last 3 days. About 10 days ago band 41 started showing up with great speeds. I only get about 105-110dBm (1-2 bars) but I was still getting around 20 mbs download speed and it worked great. 2 days ago, my G3 would lock onto band 41 at work and I couldn't get any data. Our wifi is sketchy and I need reliable LTE. After profile & PRL updates were no help, it would bounce from band 41, to 26 to 3G. Back and forth my phone was going band to band trying to lock onto a good signal but kept trying to hold onto the weak band 41 driving me nuts.
So after some research I found a way to disable band 41 & 26 for now until the network becomes more stable. If you are in an area where spark isn't fully baked and have trouble holding onto band 41 or even 26 you can do this. I now have a clean steady stable fast LTE connection at work where I need it the most.
To disable LTE bands:
1. Call or chat with a Sprint rep, ask for your MSL code, its a 6 digit number.
2. Go to you dialer and dial ##3282#, this enters you into a data menu.
3. Tap "LTE", then "edit"
4. Disable any LTE bands causing the issue. I started with 41 but ended up also disabling 26 as it was also spotty and fluctuating.
5. Then hit the back button and the phone will reboot.
You can the re-enable them using the same process at any time. I figure I'll check once a week to see if things are working. If they aren't I'll just disable them again. I would think this would also work on other spark capable devices like the M8, S5, N4, G2 but I don't know for sure.
Thanks, I hope this helps anyone that may be dealing with spotty spark LTE service until spark gets fully implemented.
Goodluck

You can also see it by using ##debug# and going into LTE Engineering option "Band" will show you. (This is likely only on LG software, not sure on CM/AOSP)
@Macguyver. THANK YOU so much for this!
I'm on the fringe of LTE/eHRPD and just by killing band 41, my reception is finally holding LTE. I've have to put my phone on CDMA just to keep data until now.
I still average 15% cell standby meaning searching for signal, but at least it holds and my battery has gotten better using LTE.
Thanks again.

Thanks for the bit of info. I turned off bands 41 and 25 to stay on band 26. Band 41 stayed between -115db and -123db and band 25 was a bit better but band 26 stays between -100db and -112db. Still not great but much better than band 41. On speed test for band 41 i was getting mostly 0's. On band 26 i am getting about 4megabit down and 2 megabit up. Never any 0's for download or upload. It does slow down but never 0's coming in on the throughput.

Which network type are you goes showing and what rom? And more importantly does it make a difference? I've found a lot of different opinions on the subject but nothing concrete, so i am still confused...
My phone is telling me my network type is LTE 14 (VZW remix rom). All the literature I read says VZW LTE band is 13. Both are in the 700 MHz range. Is there truly a difference in performance, or is there some code in this ROM that is registering as/simply making it think it is LTE 14 when it is truly on LTE 13. The only reason I care, is I got a highly rated signal booster for my office at work and have it set up in optimum conditions, and it made absolutely no difference. After reading the booster literature, it says it is for VZW LTE 13 band, so wondering if the phone is truly seeing LTE 14 and screwing up the whole setup, or what else might be the issue? Thanks for any suggestions.
After almost a year of inputting various *# and #* codes, I finally got my i717 to work on T-Mobile LTE (southside of greater Chicagoland).
This is on stock ATT JB rom and modem. On a good day I will get over 20Mbps down and 8-10Mbps up. epc.tmobile apn worked best at first, but after about a day or so, fast.tmobile apn setting did about the same. Service mode is set to Automatic and the setting in Device Info *#*#4636#*#* was set to LTE/GSM/WCDMA.
I thought all was fine until I would leave an LTE area and go into a normally (for me) 4g area
What is happening now is that I lose my LTE and go straight into EDGE. It is almost like my regular 4g is gone in areas where it used to be pretty good
Before LTE working, I was getting pretty good 4g (between 4-9Mbps down and about 1 up). This was using the same stock ATT JB rom, but with T-Mobile Blaze modem. Very seldom, like almost never, would I see EDGE. To get this I would have to go into service mode *#2263# and select WCDMA as my band preference.
If I try to use the Blaze modem, I cannot get the phone to stay in the LTE/GSM/WCDMA setting.
In a nutshell, why am I going to EDGE instead of 4g when I leave LTE?
If it matters, I am on the 5G / 100 minute $30 prepaid plan
TIA
Pretty common problem with the JB modem. You pull LTE or you pull E. For me, the best modem is UCMB4. It's an ICS modem, though, so I'm not sure how it'll work on jellybean. But you may give it a try. I pull the best speeds -- by far -- with it, and I pull consistent LTE. With the different ported modems I would have calls not go through sometimes -- weird -- and just "okay" speeds. With the ucmb4 I get solid all-around service.
I've gone from TMobile LTE to regular 4g on my mostly stock Note in Chicago. No AWS mod, no code messin, no nothin.
ATT modems will only work with tmobile refarmed 1900mhz areas. Your blaze modem is set to 1700mhz frequency band instead of 1900mhz. Thats why it works better.
Tmobile has a lot of dead areas on regular 4g with the LTE capable modem. But that's the tradeoff. Lte and refarmed 1900mhz band or just regular old 4g hspa.
no phone on Tmo 4g LTE in STL
Hey guys,
I've recently run into a problem with my unlocked i717 on TMO. It runs Android 4.1.2 (AT&T update flashed to the phone) but every since TMO rolled out their LTE in my area I get 4G LTE signals (1 or 2 bars mostly, but at times 3-4 bars) and I can send texts and data, but it cancels both incoming and outgoing phone calls.? What can I do to correct this? TMO's solution is to buy the N2 or wait til Nov for the N3. Any ideas?
Thanks...

Make sure your using the UCMD3 modem for JB. Then type *#2263# into dialer and try to set to automatic*.
Someone had this similiar problem the other day.

Go to the Dialer and Enter in ##DATA# (##3282#)

You need your MSL Code. This can easily be obtained by contacting Sprint here.
Enable Bands26 and Band41. Priority 1.
Does anyone feel a difference? My speeds here are bouncing up and down with and without this on. Sometimes its 11.38MB/s and sometimes its 7.18MB/s

According to another user, BAND 41 is highly unstable as it seems to be either Sprint kicking them out or the software is buggy, also to access any of the two you have to disable band 25 witch is LTE ON/OFF.
3G seems a little better with all three on, and the jumping is this crappy software, I hate it but I can live with it till we get a better update
Also Band 26 I believe is the old Nextel air wave, they are still waiting for iDEN users to switch over to the new CDMA push to talk and also they are still messing with the FCC on that as far as I know
Band 41 is Clearwire air wave, to find out if your in a clearwire area just go to clearwires website and search the signal maps, unfortunately I am not as of this moment.
My shining moment is when they get Band 25 and 26 working and then I will be a happy camper :laugh:

When you are connected to LTE, you have to verify that you are truly on B41 or B25. To do this you have to use the dialer code ##DEBUG# (##33284#) and click on LTE Engineering to view the LTE band your phone is currently connected to. No way are you only getting speeds of11.38 MB/sec and 7.18 MB/sec on an empty B41 LTE carrier.

I can't even connect to 4G! Every time I try it connects for about 20sec then disconnects. I believe it has to do with holder hardware for lte in my area and that a ota will need to happen to fix it.

Yes odd, I'm in Portland Oregon, made these changes and my Band shows 50. I can't find any mention of a Band 50 on the interwebs.
*edit*
Doing some testing, I reset my data connection by turning airplane mode on/off, it connected to Band 25, my speed was 4.11/1.78 mpbs. I turned Wifi back on..and now it's showing Band 50 again. I repeated the test with the same results.
Perhaps the phone sets LTE Engineering mode to Band 50 while in wifi?

Did you guys verify if you had the 4GLTE icon displaying when you saw B50? B50 means you are not connected at all to LTE. B50 is what the LTE engineering screen sits at by default when it isn't connected to LTE. Don't ask me why Sprint set it to B50 but you can verify this yourself by checking the ##DEBUG# dialer code at the LTE engineering screen when you are only connected to 3G and you will see B50...*shrug*.
Sorry, didn't see what band I was on at the time, but I took a screenshot cause I was floored by these speeds. I have not done any editing to my bands.

That is B25 LTE for sure. The speeds you posted are possible with B25 LTE. You probably don't have a loaded LTE sector which is why you have great speeds. The B25 LTE carrier can support up to 37 Mbps for a 5x5 LTE carrier so this speed is not out of the range.

It is going to be extremely hard for you to test B41 LTE like I did unless you have the proper information and the patience. It is not easy to test B41 since our stock firmware doesn't really like connecting to B41 LTE. I got a lot of disconnects and reconnects in my B41 LTE testing. For now unless you are a Premier Sponsor at S4GRU.com, I would just not even bother since Sprint made the current firmware to favor B25 LTE over B41 LTE regardless of Band Priority.

You will see the Spark symbol when we get the Spark OTA firmware update in early 2014. The intro Sprint splash screen will get updated to say Sprint Spark as well. I have played with the HTC One Max and saw what the new Sprint Spark splash intro screen looks like and the new 3G/4G icon.

I live in St. Louis and activated all 3 bands. It does become a bit unstable, but I did a speedtest by downtown and landed an unbelievable 47mbs down speed, but crashed during upload test. It was on the 41 band. I verified this through the LTE Engineering menu. But like I said, it seems very unstable.

Ya same. its unstable but much much much better than before..
Would you use a 3G only option if it was available on the G3?
I spoke to a Verizon Regional Exec today about the G3 and other Verizon phones that no longer have the option to run on CDMA only. The rep has an iPhone and regularly sets it to 3G only, especially when he let's his kids use the phone. He could not give me a reason why the G3 and other phones no longer has the ability to go to 3G only. He said he would look into this and see if it could be delivered in a future update.
Honestly I rather not have data at all then be stuck on 3G, just my opinion
I would like that option. There are areas where I play Ingress, for example, where the 3g Verizon signal is strong and uncluttered so its a much better option than LTE, which is either weak and eats battery trying over and over to reconnect, or is good but WAY oversold so there is no way to get good speeds on my unlimited data plan, much of the time.
One of the tricks we used to use on the VGNexus phones was select 3g only and save much battery life. 3g can sometimes be faster than 4g and it saves power by not running the rg radio.
Sent from my VS985 4G using Tapatalk
I can do this using com.lge.hiddenmenu. it has an intent that if launched will allow you to pick your desired frequency/bandmode. it includes lte only, cdma only, evdo only, cdma/evdo, and lte/cdmA/evdo as well as global.
i often have poor band 13 lte coverage and so it saves a lot of battery. sometimes it is nice to block 1x to improve speeds and force 3g if the signal is producing more speed then 1x. just my 2 cents,,,and if you get creative you can create a shell script to "su" then run the intent and then exit. place a shortcut on the homescreen and profit.
im reflashing my softbrick now or i would put the exact intent needed, maybe tomorrow if i remember but its network selection, network mode, something like that and way towards the bottom (last third) of the intents i viewed within hiddenmenu,apk
Please conform that the coma,option is available on works on the vs985
I've never seen 3g perform faster then 4g in my area

The GNex was one of the last phones to be affected by that. Since Qualcomm took over Android, their integrated LTE radios use no more power than 3G radios.

Completely agree, even a very weak LTE always works better for me, even over a full 3G signal at times.

Basically. I think a full 3G signal is a little faster a very weak LTE signal, but at this point anywhere there's full 3G there's LTE.
Just download a massive amount of data and the carriers will throttle you down to 3G or lower, with occasional 4G use. As for some people saying that 3G is never faster, it depends on the carrier. Verizon throttles all 3G usage in an effort to convince 3G users to upgrade to 4G.
Is anyone else whos on sprint/TMobile having issues where the phone cant decide wether to connect to a sprint or TMobile tower? When im at my home i have a very weak TMobile 600mhz signal and a strong sprint band 41 signal due to the magic box. I also can pick up the band 25 signal the box uses and my phone refuses to just use the stronger faster sprint signal. It absolutely insists on using the TMobile signal. Is anyone having similar issues? Even on wifi its causing network interruptions so i have to reload a page several times to make it use the wifi.

Mine jumps a lot but never connects to the magic box. I don't think it's enabled for B41? I have a Pixel 3XL that I activate (and deactivate my V60) when I'm at my camper which is where my MB lives.

Mine works with Band 41. Its a big one in the nearby city. It works with all sprint and TMobile bands. Its just prioritizing TMobile bands over sprint ones regardless of signal quality

I have no idea of this is related but.. I'm on T-Mobile, with T-Mobile home internet as well, and for the last several days my phone is having issues connecting and the home WiFi is doing the same thing. I'm in a rural area so my signal is weak, but it's been fluctuating WILDLY since the merger and sometimes it does seem like my phone is struggling trying to decide what to connect to. There's definitely something going on with the network at least in my area for the last 2 weeks for sure

Sounds like this will be happening until the transition is done/5G is more widespread. These are TMobile models. When mine was first turned on at the store it had the T-Mobile splash screen. The ability to access sprint towers was added via software update post merger. I figure once the 600mhz band is fully rolled out the issue will go away as a result of the signal being strong enough.
