Help with Tilt/AT&T in S. Korea

Hi, first post, searched a little...need help
I bought a tilt in December from AT&T, an 8900 non camera. I'm in S. Korea and I cannot get service. I have international roam activated and AT&T has confirmed account settings are correct...Here's the deal:
1. Phone searches for a few minutes and the I get an exclamation point.
2. Goto phone settings and see "no service"
3. Change network settings from auto to manual.
4. Phone finds KTF and SK Telecom (the two providers here in S. Korea).
5. Tries to register and generally there is no feedback, but on occasion I have received the message "Cannot read settings from the network. Try viewing settings later or disconnect data connection and try again."
6. Data is not connecting.
7. AT&T technical support (level two after the customer service rep) says the problem with the tilt is I cannot force it to use umts 2100. Then he came up with the idea that my SIM is from AT&T and that's the problem, I have to go get a local SIM from SK Telecom, but I was here in October with a Palm750 and an ATT Sim. Worked like a charm.
I'm stuck....could use any help at all!!!!
Thanks,
Steve

Thanks Kyphur...I was just installing the dll when you replied...(further searching) and now i've installed the advanced configurator. Band tab up, wcdma and UMTS 2100 selected....KTF and SK Telecom found and still nothing...
Any ideas? I'm pretty spent on this...

Anyone? this is a real pain in the you know what...I just think there is some stupid setting or something that needs to be change...Helllllppp

BUMP!! Help Please...

Are the carriers that you are referring to CDMA or GSM?

The local carriers are WCDMA/UMTS 2100 and I've downloaded the band tab dll from another post and confirmed that I am on the correct band...
I'm almost convinced it is an account problem. As of this morning my phone would continously come up with a "select" network screen (As there are 2 networks here). I select either and get the message "unable to register on the selected network, choose another or change data connection type"..
As I understand it, when I roam, my sim or phone # attempts to register across the local network to my home network and it needs authentication before I can have access...
what do you think?

bump....anyone with experience at all here?

In a simialar boat soon
I will be moving to Korea soon (Military) and I have an 8925 (unlocked) and I am wondering if I will be able to use my phone with either SK Telecom or KTF (both have GSM, I checked.)
If so, will I have to change anything in my phone? I'm using Dutty's WM6.1 Hybrid v2 5.2.19716 with the 1.65.14.06 Radio.

[Q] Nexus One not working with the Bell Mobility network either voice or data?

I just received my Nexus One which I ordered through the Google Developer program (Brightstarcorp) and I'm not able to get it working with the Bell Mobility network for either voice or data
I have a signal bars on my N1 with a Bell Mobility SIM card but it dosen’t works.
When I slide down the notification bar it say "Bell" and try this to get it working.
I have tried all solutions and have the recommended settings on the phone (also running Froyo 2.2.1-Build number : FRG83).
- I tried my SIM to another Bell phone and it works.
- I tried another Bell SIM in my N1 and it did not work.
- I'm using an active data plan card not a prepaid card.
But it works with Rogers or Fido
I tried the following :
1.Go to Settings -> Wireless & Networks -> Mobile Networks -> Network Operators: after about 1 minute I see network the currently available Bell
I click on Bell and see a signal not working.
2. Go to the dialer and type in *#*#4636#*#* this bring a hidden menu
3. tap on "Phone Information" It list the current network as Bell and also showing the IMEI and the Phone number. The IMEI and phone number are correct.
4. Hit the menu button and press "Select radio band" and click on "Automatic" .
5. Still not working I make sure radio band is set to "Automatic" then go back to the previous screen and scroll all the way to the bottom. Click under "set preferred network type" and choose through until I find one that works 1. WCDMA preffered or WCDMA only or GSM auto (PRL) it takes a few seconds from the time I click until the settings take place, just watch the signal bar at the top of the screen until it changes. Even try the "unknown" network type at the bottom of the list if the others don't work.
All the above fails.
For those of you out there who have successfully activated the Nexus One on the Bell network could you let me know which version of the phone you have.
Thanks for your suggestions.

well i am sorry to say but i dont think that the phone will work with Bell. the dev phones as far as i know are all AWS. so the only way it is going to work is if you get a rogers sim and use it on edge or a wind/moblicity sim and you can use 3G. bell does not have an edge network to back up on.

That's true. Bell/Telus has only the 3g network. The developer phone will not work. It will use edge/2g on Rogers/Fido. And will be fully supported on Wind or Mobilicity.

Nexus One with a Bell Mobility it dosen’t works!!
About Videotron?
Thanks

Enabling 3G (UMTS) in all the countries

I thought of adding this thread since, there are many people struggling to get 3G in countries other than US when they are using SIM unlocked Sprint One M8. Instead of answering many PMs I thought it is a good idea to share here.
100% working - Permanent
Using this method I unlocked 3G on couple of devices successfully and getting a speed of around 10.5MB/s (using speedtest.net-don't try to check the speed many times as the website absorbs most of the data while performing the test when speed is high-I am losing around 50MB per test)

Procedure:
1. Unlock the GSM network using the SIM unlock method as in http://forum.xda-developers.com/showthread.php?t=2718150.
2. Turn CDMA network on using the network app from https://play.google.com/store/apps/details?id=de.mangelow.network. You may change the network type by using default network preference (if it is not greyed out) or use the code *#*#4636#*#*. For me the app works quick
3. Download MSL Reader from https://play.google.com/store/apps/details?id=com.esccode.msl. And note down the MSL and save it as you may need in the future as well. Make sure you are on CDMA network to make this app work
4. Install QPST Configuration tool in your computer and make sure you have all the HTC drivers installed.
5. in the dialpad dial ##3424#. Enable Diag Mode in your phone (there will be a popup when you dial this number)
6. After enabling the Diag mode connect the phone to your computer via USB
7. Now open the QPST software in your computer. In the port tab make sure you can see your connected phone
8. From start client menu select choose service programming then click ok. Click on Read from phone
9. during this step the tool will ask for SPC, enter MSL obtained from MSL reader
10. On system tab (you may have to scroll right side) In the roaming preference choose automatic
11. On UMTS System tab :
A. Preferred service domain - Any, Pref Aquisition order-Automatic, Preferred network selection mode-Automatic
B. Under Preferred band table below select the checkbox Any BC (this selects all the bands)
12. Now click on write to phone tab, and now your mobile will reboot
13. dial ##3424# and disable diag mode. Using network app select WCDMA only to check whether you are getting 3G signal or not. Select GSM Prl mode which is pretty consistent and gives you stable 3G signal.
14. I suggest you all to try Bad Boyz Sprint ONE M8 ROMz which is stable+good battery life+good network coverage. Consider donating for that ROM developer @O.M.J.

Yes, it should work. Here we're editing only UMTS part, it doesn't alter anything in CDMA ( just don't change anything in CDMA tab of QPST)

That error is not a problem. Though you get the error it is written to the phone. Just check if you get 3G signal by selecting network mode to wcdma only. If you get the signal it's 3G enabled. You might not be getting edge because it messes up the apn setting.
In apn settings from menu select restore to default and select the right apn

I went to #*4636#*#* and chose wcdma preferred and still nothing happens

I live in Egypt and phone was catching only edge on the same APN SETTING
Now from phone setting I chose GSM/UTMS ONLY to get SIM signal which works fine ,

Damn it doesn't even show any connection
---------- Post added at 01:27 PM ---------- Previous post was at 01:10 PM ----------
I agree it doesn't show edge anymore but nothing at all ?
I am on wcdma only and phone setting is on GSM/UMTS ONLY
but nothing happens

well
this method isnt working or not anymore
also op said its permanent , which is wrong i just updated firmware and installed new rom and i am back to edge ad old settings

So, any news? Is it worth the shot?
How about 4G ?

I doesnt Work how can I undo this?

Just simple , IT IS NOT WORKING METHOD , JUST FLASH NEW FIRMWARE

Well, its working method if you follow the instructions clearly. It will unlock different 3G bands, but in your location if there is no 3G signal it won't bring the signal. It worked for me and for few others too. The whole purpose of QPST s/w is to help with this. If you failed in the first attempt try again.!!

when i try to select to select a radio band it only let me choose USA Band, and only give me USA Band, Cellular (800 Mhz), PCS (1900 Mhz) and Secondary 800 Mhz band, what should I do?

Have you unlocked your GSM network to other sims yet? You need to follow SIM unlock method first and later you need to run this. When in QPST select all bands (last option) in the UMTS tab, that should enable all the bands

do you heve the original settings from sprint my phone dont want to connect to lte anymore
@Captain_Throwback hey by any chance u have the original settings from the umts changes my phone doesnt connect to lte no more

Yes it is already unlocked, I have EDGE connection, sometimes I can connect to 3G but calls drop and the connection is not stable, so its not usable.

[Q] Problem with 3G data connection

Hi
With my friend purchased 2 Nexus 6. (I bought it from Netherland and my friend in U.S) In our city we have 3G signal. Most of the time I cant connect to 3G connection and only can use 2G (EDGE) but my friend at same time and same place and same operator connect to 3G!
we have the same build number on our phones.
today I try to solve my issue and got some information about this problem that I’ll explain it. Is there anyone can help me to solve it?
In setting >> More >> Celluar networks >> Prefereed network type when i select LTE a green circle added that show now LTE is selected (picture 1) but when I close this menu and again open it , LTE is not selected (picture 2). I tried more than 10 times in different places, even flash latest nexus 6 factory image and test with my friend sim.
After that I tried with *#*#4636#*#* secret code and went to Phone information saw my preferred network type is : LTE/GSM auto (PRL) , and my friend’s phone is LTE/GSM/CDMA auto (PRL).
I changed my settings to LTE/GSM/CDMA. again when i close this page and reopen it it automatically changed to LTE/GSM. (picture 3)
All of our settings are the same. but just when we dial *#*#4636#*#* and go to phone information >> select top menu >> select radio band we have diffrent datas.
My phone just have USA band but my friend has 3 more option (picture 4)!
I hope someone can help me to solve this terrible problem.
P.S. becuase of poor 3G signal in some areas I can't choice WMCDA Only option
thanks

first off you and your friend have different nexus 6. sounds like your friend has a US version and you have the international version. the difference between the two is the radio/frequencies included.

[HOW TO][R&D] : SM-G900P working with any LTE band.

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.

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.
