Is anyone else running this cab file??
Before loading it, I pulled it apart with a cab editor to see what it was. I was very excited to see that it uncovered the radio band selction capabilities, so I quickly installed it.
But this where things got funny. I refuses to give me the option for the for GSM 1900, although it is clearly called out in the registry edits the cab lays down. I am running the 1.13 radio, with system 1.40.00, and was wonder if anyone else can verify this as a problem? I am wondering if this is a software issue in either the cab, system, or radio... Or to my horror is the SX66 retarded to triband???

Ok, looks like TheLastOne answered my question in another post. Funny that the site search failed to turn this up:
1) Phone Band Selection: BandSel_BAWWE_140921.sa.CAB
- I've played with this a bit, their cab is actually ****ed up, as they have tried to get 6 selections onto the page when only 5 are possible. Through the registry you can have any band configuration you want selectable. I personally LOVE this feature.
GSM 1900 is the 6th selection, hence it doesn't show up. But this now leaves a glaring question, what are ALL the selectable options? I note the 900/1800 option with a value of 3, but is there a 850/1900 option(This would be prefect when I go to aruba), and what is that value??
GSM900 has a value of 1
GSM1800 has a value of 2
GSM900/1800 has a value of 3
GSM1900 has a value of 4
Automatic has a value of 7
gsm850 has a value of 8
So, what are values 5 and 6?? I could set those values, but I have no idea how I'd check to see what band I am current using. Anyone got any thoughts?
-Chris
Either 5 or 6 is 850/1900, from my tests, but I forget which.
If you don't mind, how did you determine that?
-Chris
In my location, I have access to two GSM networks, one which is exclusively 1900 and the other is 850. Set to either 5 or 6, I could get on both. (So I'm not positive it's EXCLUSIVELY 1900 and 850, since there is no 900 or 1800 here to test).
I did this a bit ago, so I don't properly remember.
The value is a bitmask:
bit 1: 900
bit 2: 1800
bit 3: 1900
bit 4: 850
so 5 means 101b - 1900+900
6 means 110b - 1900+1800
Setting 7 would make GSM to use 900, 1800, 1900
Probably the GSM part also tries to register on 850Mhz when 1900 is selected.
Mamaich,
You rock. You never cease to amaze me. Very cool, thanks.

Can you post a link to this CAB file?
Modified Band Select CAB for USA
I modified the CAB for USA only 850, 1900 and Auto
I ran the updated CAB file you posted here, seems to be working ok, although signal strength (on the new bands) seems to be weaker than what I had before installing the cab. I am wondering, is there ever away to revert back to the original band options or settings ?
I am wondering the same thing, because NONE of the 3 options i had available to me when I installed this (Auto, GSM 850/1900 (NA), GSM 900/1800(Euro/Asia) were selected.
When I selected Auto, I began ROAMING, and I'm not certain why. The only way I know of to return this back to factory state is to hard reset.
Does anyone have THE ORIGINAL CAB, before the mods were made so that ALL options were available?? I'd really like to have that cab so that I can see what option my PDA2k on Cingular was using...
Here is the original CAB file, it did not work on my SX66 (see the first few posts on this thread) so I modified it to use only 850/1900 and Auto. I have had no problems with the modified CAB. Signal strength has not been degraded.
thanks, Cruzzer.
the modified CAB put me into permanent ROAM no matter what frequency I chose (or killed the phone entirely because there wasn't a 900/1800 tower).
I managed to get a hold of Chris and he helped me make some registry mods that gave me the original functionality back.
Interestingly enough, I had to put the phone thru a couple of different SR's before it would stop roaming, even after switching back to JUST 850.
Goofy, huh?
Care to go over the registry edit you made? Thanks.
Question
First of all, thans for the Band Select created by Cruzzer for US users. After I install his band select, it's the first time that I can use my phone in my office located in a basement. But I have a problem. In his band select, there are three options, automatic, GSM 850, and GSM 1900. When I selected automatic, my phone couldn't find the network. But when I selected GSM 850, it works perfectly. At first, I understand that by selecting my phone to automatic, my phone should search both GSM 850 and GSM 1900. But I don't know why it always show no network. Did I do anything wrong?
By the way, my phone is O2 XDA IIs brought from Thailand. (O2 Asia)
I believe that there is a bug in BA when working with GSM850.
In fact, automatic should search between GSM850, 900, 1800 and 1900.
Usually when using "automatic" where GSM850 networks exists, makes BA not being able to find any network.
Are you using WM2003SE ?
JP
Yep WM2003SE
Yes, I'm using WM2003SE.
I also tried another band select created by one of our members in http://forum.xda-developers.com/showthread.php?t=297099 His band select gives four options:
1. automatic
2. GSM 850/GSM 1900 (north america)
3. GSM 900/GSM 1800 (Europe)
4. Reset Values to Zero
When I selected GSM 850/GSM 1900 (north america), my phone had no signal. So, right now I have to go back to BandSel_BAWWE_140921.sa.us and manually select GSM 850.
Yes, unfortunely, that seems to confirm my teory.
If it works for you at 850, keep at that. Just remember that if you upgrade to WM6, band selection will not be available and it will be locked to your choice done in WM2003, in this case 850.
Your BA, will no longer be quad-band (the same as mine).
JP
Too bad
Thanks for confirming the bug in BA. Too bad. I want to upgrade to WM6 but I know there is no way to select which band in WM6. So...I'm stuck with WM2003SE. I wonder, can we edit the registry to manually select the GSM band in WM6?
I've tryed and some other did also, but it seems that both the .cab and also registry tweaks for band selection do not work on WM6.
It does not mean that you will have a problem with WM6, but rather that the band that you have selected on WM2003 will remain "locked" when using WM6 and cannot be changed.
In my case, i'm using the 900/1800 band selection and it works just fine with WM6 (i've used Helmi's and now i'm using Xplode's) but i cannot select 850 for example.

Is there any way to configure the UMTS Band settings on the Trinity / D810? I ask as the ROM provides the following options:
Network Type:
Auto
GSM
WCDMA
GSM/UMTS Band:
Auto
GSM(900+1800)+UMTS(2100)
GSM(1900+850)+UMTS(1900+850)
UMTS(2100+800)
Now ... for the HSDPA Network in Australia for Telstra (Next G), I need the phone to work on the UMTS(850) Band. However, by selecting the option above where the only UMTS(850) is available means that the alternate 3G Band (not HSDPA) of UMTS(2100) is not available, and the GSM Bands in the same selection are not valid for the Australian market.
Couple of queries, and I hope there are ways of configuring the device to achieve this (without getting a new ROM to support it):
When a Band selection is made, what is the order which the device uses the connections? ... i.e. if the selection was GSM(1900+850)+UMTS(1900+850), will it look for UMTS or GSM first? If UMTS, which band - 1900 or 850?
When Auto is selected, I am guessing it uses each option in the list until it finds a valid network? This would mean that for Australia, if left on Auto, you would never select HSDPA for Telstra as it would find the 3G UMTS(2100) network first (non-HSDPA).
My assumptions are that if left on Auto, it looks based on list order (which is the network order in the registry). So, for Australia, I need a setting like the following:
GSM(900+1800)+UMTS(850+2100)
Is it possible to create this Band Selection without a new ROM?

The new Dopod ROM has the same band selections as yours does. I tried changing the selections to manual with bad results. I just leave it on auto now.

I could do that to, but it would mean I don't get HSDPA. I have verified this. The only way to get HSDPA is to set the Band selection to the one with UMTS(850) in it ... this is not ideal, and that's why I posed the question to this forum.
No one??
I am guessing that no one has ever come across this, or needed to do it?
Registry Patch
This Registry patch works for the Hermes. It might work on the Trinity.
[HKEY_LOCAL_MACHINE\SOFTWARE\OEM\PhoneSetting\BandType]
"ItemCount"=dword:00000006
"ItemName1"="Auto"
"ItemName2"="GSM(900+1800)+UMTS(2100)"
"ItemName3"="GSM(1900+850)+UMTS(1900+850)"
"ItemName4"="UMTS(2100+800)"
"ItemName5"="GSM(900+1800)+UMTS(2100+850)"
"ItemName6"="GSM(900+1800)+UMTS(850)"
"ItemValue1"=dword:00000000
"ItemValue2"=dword:00000001
"ItemValue3"=dword:00000002
"ItemValue4"=dword:00000003
"ItemValue5"=dword:00000004
"ItemValue6"=dword:00000005
[HKEY_LOCAL_MACHINE\SOFTWARE\OEM\UMTS\BandSelection]
"Band"=dword:00000005
You really just need to add ItemName5 and 6, and ItemValue5 and 6, and change the ItemCount from 4 to 6 (as you added two options) using your favorite Registry Editor.
Do a soft reboot of the phone. Now you can select the NextG option GSM(900+1800)+UMTS(850)
3G connection
I drive around the Perth Metro area a lot for work and am finding that if left on Auto the connection is lost quite often mid call. How have you found the 810's management of the bands? And the auto fallback? Is there a way to set the fallback threshold so it drops back if under 2 bar signal strength? At the moment it sits on 1 bar strength and drops out mid call.
Has any been able to get 3G to work in the USA yet?
thank you,
jdm
I would say that it is imminent that the US version of the S730 will be released soon. AT&T or T-Mobile may pick it up (T-Mobile's 3G network in NYC just went live, but there are no phones). If so, I would suspect that some of these crafty folks (like Alcaline) would be able to extract the radio ROM, and make it available for the S730 that we all have (the european version).
But, here's the most important part... It all depends on whether or not the European version of the S730 has the radio chipsets that will support 3G on the frequencies that are 3G in the US. There is no known answer "available" to this, so it can only be discovered by testing.
The current S730 uses the 2100 band for 3G speeds and ATT is deploying 3g on 1900 and 850 I believe and they sell a decent ammount of 3g phones. T-Mobile is working on setting one up on the 1700/2100 band but I dont care for T-Mobile.
I have watched my phone at times flip into 3G mode for a few minutes then revert back to Edge, its trying but cant work properly without the right frequencies.
Check out the chipset datasheet. Bottom of page three explains the specific radio chipset combos and their support for different freqs.
I suppose, to save on manufacturing costs, they could have used the single chipset that supports 3G on all freqs (RTR 6285), but I believe this is unlikely due to the difference in model number that was submitted to the FCC (European version: WING220, US version: WING200).
Who knows though.
3G in US
Hermes models had different model #'s HERM100, HERM200 and had the same radios, in some cases minor difference such as case style, i.e removal of video calling camera etc. With any luck we have the RFR6500 + RTR6275 Combo, or as you mentioned the RTR6285 and just not a radio rom that allows 1900+850 3G. I was looking on the FCC site and they have some interesting screen shots, one of which shows one(s730) with what appears to be the front camera covered up and another which shows a radio rom(R 0.27.03.05B), one that, to do the tests would likely need to support 1900+850. Check Page 250 / 11 in the PDF. However, also in the test is the lack of any mention of 2100 Mhz test, which would suggest that either the US 3G Radio won't support 2100Mhz or that it indeed has different hardware that won't support 2100Mhz. At any rate it would be interesting to know if anyone has tried to flash one of the pre-prod roms for the wing 200 onto the wing220 and see if they are able to connect up to 1900+850 3G.
http://gullfoss2.fcc.gov/prod/oet/forms/blobs/retrieve.cgi?attachment_id=890469&native_or_pdf=pdf
I suppose only time will tell.
Wow... nice investigative work. Very interesting. I'll start hunting around for the ROM.
[edit]
Searched google and, my favorite, napalm with no luck. I wonder if we can lure an FCC testing engineer into the XDA-dev realm. muahahaha
I was searching some of the other posts, and it appears that most of the pre-prod radio rom testing had been focused on GPS functionality. Has anyone been able to throw on any of the pre-prod radios with an ATT SIM and tested to see if it can connect to WCDMA -> US Band (1900+850) ??
I have no possibility to check the 3G in the USA from my location in Norway.
But just to get this clear, because I have changed my Radio more often then most people change their underweare.
Is everybody able to select WCDMA and then US Band in the settings?
I dont know if this is selectable on all devices or if this is made available after my radio flahings.
I believe all S730's have the following options available.
Network Type:
Auto
GSM
WCDMA
Band Type:
Auto
US Band
Euro Band
Japan Band
For it to actually be able to operate on all of these frequencies I believe it would need to use the the RTR6285 chipset as the other 2 combos would not support all of the different frequencies combinations.
US Band -> GSM 850+1900 / UMTS 850+1900 (ATT)
Euro Band -> GSM 900+1800 / UMTS 2100
Japan Band -> UMTS 2100+800 (not positive on this one)
If I change band to from Auto -> WCDMA I do not get an error but no 3G Icon and all calls fail. If I then go and change to US Band while having WCDMA selected it indicates that it cannot change to that GSM/UMTS Band. Also interesting, If I stay on WCDMA and select Euro Band, no error, but of course all calls fail. I then tried to change to Japan Band, no error and no phone calls. Finally I am still on WCDMA and I switch to US Band and I get the error that indicates I cannot change to that band. So, I would be interested to know Alcaline if you see the same behavior on some of the other radios you have been trying to see they allow the switch to WCDMA / US Band combo.
Thanks
Can anyone else confirm this behavior on any of the other Radios out there?

I have the ability to tell my phone I am in the states, but it does nothing (default settings though)
Was the US version (WING200) of this phone ever released? Or has anyone gotten the EU version to work on any US 3G networks? Wondering about T-Mobile...
Hi everyone,
I really appreciate the work everyone puts in on this site, it's amazing. This past week, I bought a Samsung Galaxy S5 (SM-G00P, the Sprint Model)
So I will edit this guide later on with pictures, but right now I just need to write down what I've discovered.
I'm also not sure if everything I say is necessary / absolutely will work for you, also if you try to do some of this on your own, it's your own responsibility if something bad happens.
--------------------------
Short Requirements
--------------------------
EFS Professional
QXDM Professional (I believe QPST must also be installed)
Cyanogenmod 12.1 with BusyBox
So, what I have done is flash Cyanogenmod 12.1 for the SM-G900P on the phone and installed BusyBox. Then I have downloaded EFS Professional on my computer.
Then enable USB Debugging (adb debugging.) Open up EFS Professional, go to the Samsung Tools tab and select the bottom option with includes Modem + Diag. Open up QXDM Professional, go to the Communications tab up top and enter in the Samsung port (COM9, for example) and make sure to check it off.
Go to "LTE" option in QXDM and enter in "0xFFFFFFF3FFF" AKA "17592185995263" underneath ID 06828 and ID 06829. There should be two config's per ID, I entered in both. (It should be noted that "0xFFFFFFF3FFF" will enable "ALL" LTE bands and may not be necessary)
----------------------------------------------------------------
Finicky Step (That seems to enable LTE, somehow)
----------------------------------------------------------------
Now restart the phone, just to eliminate any possibility of errors. Go to: Settings > Mobile networks > Network operators > choose AT&T
Now I have done this step differently a few times, but this is what seems to get rid of HSPA+ and H to force LTE on (not sure why)
Sometimes I have selected T-Mobile instead of AT&T and let it time out, then select AT&T or just restart the phone and select AT&T.
I really don't seem to understand why this works like this, maybe someone has some more insight? If I restart the phone, it goes back to HSPA+.
I know this is using AT&T's LTE bands, because LTE Discovery shows Band 2 a lot of the time. Weird thing is, sometimes it shows Band 25, even though I believe that is a band that Sprint uses.
CM13 - Does not have "Network operators" option.
I'd like to write a script that either automatically goes through the menus on boot, or can automatically disconnect from the network and connect to the correct network.
ALSO WORKS,
If you download the "Radio Switcher" app, set to GSM auto (PRL), then set to LTE/GSM auto (PRL) in that order.
Turn OFF radio, turn radio on, select GSM auto (PRL), let it connect, then select LTE/GSM auto (PRL) and it will connect to LTE immediately.
Mostly interested in the underlying causes of why this works. Could be applied to more phones in general.
Earlier when I was adding LTE bands it seemed like they added (showed up on QXDM) but LTE would never connect. Something interesting is in the program "DFS" 6829 wouldn't show the edited changes or let me edit them, QXDM seemed to work ok though.
Other discoveries:
Once you initially set it to LTE, sometimes it randomly goes back to HSPA+. But I've had LTE last good amounts of time (1-2 hours)
If you make a phone call it switches to HSPA+ but won't revert back to LTE.
If you open up the "Radio Switcher" or "Network" app (they are the same) it sometimes will just go back to LTE immediately, other times you simply need to run the Ping test.
I think it keeps reverting back to HSPA+ after a while because it eventually connects to Band 25. Not sure if I can access the Service Menu (*#0011#) on Cyanogenmod, maybe to set priority? Might actually be because of too many different LTE bands enabled.
I'll try adding only AT&T's bands to see how things work.
So far, tried bands 2, 4, 5, 12, 17 - can't get LTE. Band 2 only, can't get LTE. Only getting HSPA+ on GSM auto (prl) and HSPA on LTE/GSM auto (prl). Tried both decimal and hex values in QXDM. For example, I've entered in 2 (decimal) and (0x2) and (0x02)
Wanted to point out here, phone booted up with service immediately.
Tried all bands except for 25, no LTE, a little more laggy, but not as bad as when band 25 is enabled.
Tried band 2 and 25, Got LTE, takes a lot of time when turning on phone for service to appear and when changing radios.
So, for some reason band 25 is needed in order to get LTE on other bands.
With bands 2 and 25 only enabled for LTE, I rarely drop to HSPA+.
It has only happened twice in the past 6 hours. (The LTE Discovery App has an option to cycle the network when LTE disconnects, which seems to only refresh HSPA+ once it goes back)
---------------------------------------
So I went back to stock firmware on the Touchwiz 5.0.
"Network" and "Radio Switcher" apps don't work, but "Advanced Signal Status" does.
Same steps work here as above in "getting" LTE, also there are more options to choose from.
LTE/WCDMA seems to work too.
Problem is I am getting this error:
"LTE: ESM - 33 EMM - x"
and can't connect to the internet, only band 25 seems to be connecting, unlike band 2 last time (maybe this is because I was on klte CM ROM).
I also should note that it now says "GPRS service: Disconnected"
In ServiceMode (*#0011#) I haven't had any luck, in the cases where I can do anything with the LTE bands it is only for 25, 26, and 41. Other cases show more bands, but it says something like "not
supported" to edit anything.
I also tried messing around with the ##3282# LTE settings, only shows 25, 26, 41 bands and I can't change the priorities.

This is because Straight talk doesn't support Voice over 4G, so your data connection has to fall back to 3.5G in order for a call to be placed.
Some more observations, I used this app called connection stabilizer which constantly pings for network connectivity. I think this might help keep the LTE up longer, when driving I will eventually lose LTE and get a ping failed. I'm not really that sure if this helps or not, but it's a total pain because you need to keep data on. One more thing to note is on the "mobile network settings" page I never see "GSM/WCDMA/LTE" option
I believe the only way for a permanent solution is to be able to flash another modem on the phone (such as SM-G900A or SM-G900T). Problem is Odin will never let me, I've tried everything to get another modem flashed with no luck, if anyone has any ideas or solutions please let me know I'd love to get this phone working consistently with LTE, although it seems that I may as well just return it and get the SM-G900T as it supports many bands (including the AT&T bands) Only thing is there is no FM Radio on the T-Mobile version, but I was planning on using Cyanogenmod anyways and NextRadio doesn't seem to work with the SM-G900P with Cyanogemod. Maybe there's a build.prop edit to allow it? Or maybe it's a kernel issue.
Did you make any further progress with LTE on touchwiz? Been tinkering and trying to get T-Mobile LTE (band 2 & 700Mhz) working on my own G900P.
Something interesting I found is that if I have it set to LTE/GSM (autoPRL) sometimes it will remove (hide) any T-mobile APNs and force you to use "sprint wholesales" and "global roaming SPCS". (switching back to GSM/WCDMA restores the T-mobile APNs. I wonder if that can be overriden by finding where those defaults are in the system files and editing them to be T-mobile...
Since the G900P is a CDMA phone, I've assumed that to get LTE on a GSM network I'd have to edit NV values in QPST/QXDM/EFS Professional to enable some bands. I've done that before on a G900V with KitKat on it and it gets GSM LTE fine.
The past few days I've looked for a solution and yesterday I was finally able to seemingly enable diagnostic mode and get into my G900P that has Marshmallow 6.0.1 on it. It was a headache just getting in to read the values. QXDM read the NV values but they only went as high as 6754; in the past the LTE bands needed enabling on 6828 and 6829. I don't know if the NV system has changed in Marshmallow or if my versions of QPST/QXDM/EFS Professional are outdated and won't read everything in 6.0.1 or some other problem. I wasn't able to make any band changes. Maybe somebody with more experience will have better luck.

In my case... I've managed to get it to look like the bands in question are enabled via QPST/QXDM (confirmed with readback through DFS/EFS pro)... but the LTE radio still doesn't activate (band ID in the debug screen is -119, LTE radio is "idle")
the write "block" you're experiencing is something Qualcomm/Samsung put in the android code as a binary blob (no source for people to find and disable/reverse engineer/bypass). Third party mods (CM etc that are not touchwiz kernel based) don't have this block.
I think I'm SOL with my only remaining option to try flashing a custom ROM. The LTE radio in my device simply won't start on any band other than 25.

Sorry for the late reply, I basically gave up after not getting anywhere with hours spent on this, I tried flashing alternative modems and nothing would work.
So this is what happened to me. It would show it alternating between bands 2/25.
My theory is even though I was able to modify the bands on the device (the values registered) it didn't do anything.
It seems as if disabling bands is the only thing that really works.
CM13 (kltedv) seemed to run as an okay ROM for the Sprint S5, it was easier to force the 2/25 LTE band on, problem with this is when you disconnect from that tower or place a phone call it will revert back, plus there comes to be issues with texting/calling by forcing it on LTE and there seems to be issues with switching between LTE and HSPA+
I recommend purchasing a SM-G900T as it provides a multitude of bands and the bootloader is unlocked, only downside is the FM Radio does not work.
*If anyone gets other LTE bands working on this phone, PLEASE post the solution here it would be insanely appreciated*
Yeah... there was some discussion as to whether the 900P doesn't have band calibrations for non-sprint LTE bands.
I'm not really looking for a new phone, just figured that if I could get LTE it would be a nice bonus.
Re FM radio: I looked into this some a while back, it works on the G900P because they have the correct radio transport code in the radio app... (other radio apps can't see the FM chipset) there are actually kernel modules (iris_radio_transport.ko) which should provide a standard FM radio interface for the G900P. Be interesting to compile those for a non-sprint phone and see if other models also have FM radio.
Well this thread kind of got my hopes up, then back down again.
I would really like to be able use LTE with this phone for AT&T. Having a difficult time trying to get it to read with QPST. EFSpro works fine though.

Other discoveries:
Once you initially set it to LTE, sometimes it randomly goes back to HSPA+. But I've had LTE last good amounts of time (1-2 hours)
If you make a phone call it switches to HSPA+ but won't revert back to LTE.
If you open up the "Radio Switcher" or "Network" app (they are the same) it sometimes will just go back to LTE immediately, other times you simply need to run the Ping test.
I think it keeps reverting back to HSPA+ after a while because it eventually connects to Band 25. Not sure if I can access the Service Menu (*#0011#) on Cyanogenmod, maybe to set priority? Might actually be because of too many different LTE bands enabled.
I'll try adding only AT&T's bands to see how things work.
So far, tried bands 2, 4, 5, 12, 17 - can't get LTE. Band 2 only, can't get LTE. Only getting HSPA+ on GSM auto (prl) and HSPA on LTE/GSM auto (prl). Tried both decimal and hex values in QXDM. For example, I've entered in 2 (decimal) and (0x2) and (0x02)
Wanted to point out here, phone booted up with service immediately.
Tried all bands except for 25, no LTE, a little more laggy, but not as bad as when band 25 is enabled.
Tried band 2 and 25, Got LTE, takes a lot of time when turning on phone for service to appear and when changing radios.
So, for some reason band 25 is needed in order to get LTE on other bands.
With bands 2 and 25 only enabled for LTE, I rarely drop to HSPA+.
It has only happened twice in the past 6 hours. (The LTE Discovery App has an option to cycle the network when LTE disconnects, which seems to only refresh HSPA+ once it goes back)
---------------------------------------
So I went back to stock firmware on the Touchwiz 5.0.
"Network" and "Radio Switcher" apps don't work, but "Advanced Signal Status" does.
Same steps work here as above in "getting" LTE, also there are more options to choose from.
LTE/WCDMA seems to work too.
Problem is I am getting this error:
"LTE: ESM - 33 EMM - x"
and can't connect to the internet, only band 25 seems to be connecting, unlike band 2 last time (maybe this is because I was on klte CM ROM).
I also should note that it now says "GPRS service: Disconnected"
In ServiceMode (*#0011#) I haven't had any luck, in the cases where I can do anything with the LTE bands it is only for 25, 26, and 41. Other cases show more bands, but it says something like "not
supported" to edit anything.
I also tried messing around with the ##3282# LTE settings, only shows 25, 26, 41 bands and I can't change the priorities.

Also I got the values for 6828/6929 to stick. They are there when I reboot and everything. My biggest issue now is forcing LTE. I'm on CM13 and I have tried the prl method you mentioned but no matter what I try, LTE won't activate.

Hi everyone,
I really appreciate the work everyone puts in on this site, it's amazing. This past week, I bought a Samsung Galaxy S5 (SM-G00P, the Sprint Model)
So I will edit this guide later on with pictures, but right now I just need to write down what I've discovered.
I'm also not sure if everything I say is necessary / absolutely will work for you, also if you try to do some of this on your own, it's your own responsibility if something bad happens.
--------------------------
Short Requirements
--------------------------
EFS Professional
QXDM Professional (I believe QPST must also be installed)
Cyanogenmod 12.1 with BusyBox
So, what I have done is flash Cyanogenmod 12.1 for the SM-G900P on the phone and installed BusyBox. Then I have downloaded EFS Professional on my computer.
Then enable USB Debugging (adb debugging.) Open up EFS Professional, go to the Samsung Tools tab and select the bottom option with includes Modem + Diag. Open up QXDM Professional, go to the Communications tab up top and enter in the Samsung port (COM9, for example) and make sure to check it off.
Go to "LTE" option in QXDM and enter in "0xFFFFFFF3FFF" AKA "17592185995263" underneath ID 06828 and ID 06829. There should be two config's per ID, I entered in both. (It should be noted that "0xFFFFFFF3FFF" will enable "ALL" LTE bands and may not be necessary)
Hi! Thank you so much for the hard work. I've try to follow this tutorial but I'm stock somewhere. I'd really appreciate if you could help me. I don't see "LTE" option in QXDM. I managed to get in some places where I can see LTE but I don't see where I can edit anything to enter in "OxFFFFFFF3FFF" AKA "17592185995263”

Hi, in the NV browser there should be a tab that has a pull down menu where you can just jump ahead and get to 6928/6929.
Out of curiosity, what baseband firmware are you on?

I'm on CM13, I'm sorry I just realize that I'm on a different firmware than the one in the tutorial.
If you mind, let me please take a little time to explain my case.
The phone had several problem (you can ask details if you want) I went to my network provider to see if they can fix it, the representative told me the phone needed to be flashed but since I didn't bought it from them they could do nothing. And when I got back I searched Google to see what it is about.
I could see under setting that my phone was a SM-G900T. Than I downloaded the stock OS for that specific version of the Samsung Galaxy S5. And any other required stuff like Odin, Samsung USB drivers and more. But the freshly downloaded firmware failed to installed on the phone. I finally managed to understand when I saw in the download mode screen that the phone was a SM-G900P NOT SM-G900T.
Than I downloaded the stock firmware for SM-G900P and it success to install on the phone. The phone was then working perfectly fine. But I couldn't get LTE since my carrier's band for LTE is band 3 (1800). And I tough if it had SM-G900T previously and at this time it was compatible with my carrier's LTE band cause T-Mobile also has band 3 for LTE, that's suppose to mean that I can get SM-G900T aboard or to have band 3 on it.
Maybe I give too much detail, but I want to make sure you fully understand the case and thank you for your help. We're almost at the end (loll).
Based on my reading, I tough installing a custom firmware would resolved the problem and that's why I installed CM13 (the first time I could say I love android ... I'm more accustomed to iOS) to find that I was not that right (it get even worse cause now I receive no data at all unless I'm on WiFi). Than I found this tutorial and an other one on XDA saying that it's possible to enable other bands on the phone.
But any tuto I use I get stocked at some point and I'm so novice to that field. But I can follow institutions:good:
Actually I can't access the USB settings screen and there's only two codes that works on it : *#06# for imei and *#*#4636#*#* which open a screen named "test".
I wish I gave useful details on the case, if there's anything else you need to know fell free to ask.

But beware, I'm not sure if this works. I have countless of times tried to do this mod and successfully completed the LTE mod, I still don't get LTE. No matter what radio I set it on. I even flashed back to my stock firmware, rerooted, and tried again to see if I could have more capabilities in service mode. It appears that you can only enable/disable the LTE bands that are equipped to the hardware.
Meaning that my LTE Modem most likely can only use band 25,26,41 as it's the only bands to be coded in my modem firmware. However, I was able to unlock band class 10, because it was built with the hardware.

Whoa easy there, my 6928/6929's description is LTE BC CONFIG
LTE BC CONFIG DIV.
In the NV browser, there should be pulldown menu, within that menu, there should be an LTE category. Where LTE BC CONFIG/LTE DIV (6928/6929) should be. If you can't find it then I can may no longer be of assistance as the efs may be different considering the differences you mentioned about firmware earlier.

Hello all,
I recently changed my phone carrier, and I noticed phone doesn't go in LTE+ mode anymore. Apparently, the phone is able to aggregate band 3 and 1, which was the combination my previous carrier was using, but not 3 and 7.
I read a bit around, and found out some useful discussion here:
http://en.miui.com/forum.php?mod=redirect&goto=findpost&ptid=392070&pid=10016974
which gave me the opportunity to understand how to set the carrier aggregation on different bands, and avoid to add any combination on band 7 which apparently isn't managed properly.
So, I used QXDM to change the nvram values on band 3 CA (default is 5, which is band 3+1 aggregation), and my phone was able to aggregate 3+7 bands, but that leads to a loop between LTE+ and LTE, which ends with phone in H.
After reverting the changes, phone goes normally in LTE.
Is there any way to enable Carrier aggregation on Mi 5, on combinations not originally present in the firmware? Or does Mi 5 lack the hardware to do so?

I dont really have the technical knowledge, but if you look at some of band 1 configs, there's a few values that are set for carrier aggregation that are not set for other bands. I think we need to configure a few more things than just enabling the CA values. Been trying to figure this out for some time. Too bad i don't have any other phone with proper ca support to compare
does the *#*#717717#*#* only works in MIUI ? currently using OMNI rom

There are some, only usable one in Italy is on band 3, it aggregates 3 and 1, but is really rare operators use this config.
You can enable the engineering mode with adb
