EDIT: 21/06/2017 THIS MAY NO LONGER WORK DUE TO NEW SECURITY. LEFT HERE FOR REFERENCE ONLY
WARNING: THIS PROCEDURE MAKES DANGEROUS CHANGES TO YOU DEVICE, I DO NOT ACCEPT ANY RESPONSIBILITY FOR DAMAGES
EDIT: FINDINGS SHOW THAT GSM MODELS DO NOT SAVE THE BANDS AFTER REBOOT. QPST/QXDM MAY SUIT BETTER FOR THIS. CDMA MODELS SEEM TO BE FINE AT THIS STAGE.
For GSM MODELS (please click unhide content below) thanks to @guidojusto, be sure to thank his post

Well I did find some little time to do a guide trough the process to change LTE bands, take in consideration that I did this process on my HTC One M9 Developer-Unlocked version (Should be the same as the AT&T one).
I DO NOT ACCEPT ANY RESPONSIBILITY FOR DAMAGES
You will need:
QXDM Pro 3.12.714 (I do not have any links, and deleted my installer, I’m sorry) .
HTC Diag drivers (Find these drivers on first post).
DFS CDMA software (Also find the link to this program on first post).
NV LTE Calculator (I found a couple of apps on the Play Store, I used both of them in order to check if the values matched).
Phone should be:
Rooted
Developer Mode Enabled with USB Debugging activated
S-Offed (Not completely sure about this one, I'm while doing this process though)
In order to install the drivers on Windows 8 and upcoming OS’s you will have to turn off signature driver verification.
Also, please, use the two screenshots provided in order to make things easier for you.
1.
Open a terminal where your adb folder is and run
Code:
adb shell
su
echo 1 > /sys/devices/virtual/android_usb/android0/f_diag/func_en
Note: After this, you need to install the diag drivers you download before, when you are ready, continue.
2.
Open DFS CDMA software and look for the COM HTC Diagnostic Interface, take note of the COM port the phone is using. On the screenshot provided is COM 3, yours may differ. Close the program now.
3.
Open QXDM Pro and go to Options --> Communications… Check for the COM with diagnostics (In this case COM 3) (Step 2 on the screenshot). Then look for Target Port and select the COM your HTC Device is using from what you saw while using DFS CDMA software on the beginning (Step 4 on the screenshot). Click OK (Step 5 on the screenshot).
4.
Go to Category Filter and select LTE there.
5.
Look for the first value 06828.
6.
In Fields press Read (Step 8 on the screenshots)
7.
Save the value to somewhere safe, as a backup of what the phone is currently using for connecting to LTE antennas.
8.
Input the number you want to use (Use NV LTE Calculator or other program to get the right number for the LTE bands you want to use) (Step 9 on the screenshots).
9.
Press Write. Close QXDM Pro now.
10.
Go again to your adb terminal and type
Code:
adb shell
su
echo 0 > /sys/devices/virtual/android_usb/android0/f_diag/func_en
11.
Profit!
If you want to check if these settings stick after reboot, then you reboot the phone, and do the same steps up to the step 8 where you need to read the values the phone has, if it has the same values you have manually changed it means the process worked perfectly.
Hope this helps @stifilz you should thank him!

Hi all,
I have been playing with this for the last couple of days.
Hopefully this will help you to change the network bands available to your HTC One M9 - All variants should work - Tested on Sprint M9 and GSM M8.
Prep:
You will need DFS CDMA tool from http://cdmatool.com/ demo version will work (create an account too, it is free and you do not need to add credit)
You will need HTC Diag drivers (attached)
Preparing your device:
Device Should be S-OFF (S-ON may work)
You must have ROOT
ADB must be enabled
Firstly USB diag mode must be enabled, on CDMA devices you can use ##3424#.
This option is not available for GSM devices. So we have to echo '1' (which means turn on) to the f_diag USB mode, this is set to '0' (which means turn off) by default.
So you have to use the following code:
Code:
adb shell
su
echo 1 > /sys/devices/virtual/android_usb/android0/f_diag/func_en
This is the code available on my Sprint M9 but should be the same on other variants.
I have tested this method on my HTC M8 GSM and it does connect to the PC
M8's code is slightly different.
This should have enabled DIAG mode and you should have a new device on the PC.
Please install driver by manually updating the unknown driver.
Install DFS CDMA Tool if you haven't already and open DFS.
I should show a login screen, you may need to create an account (I can't remember). Log in and close that window and the main window should ope wait 50 seconds (demo limitations).
You should be presented with your device on the 'Equipment' tab. Mine is COM3 HTC Diagnostic Interface (COM3).
If it is not showing please check you drivers and close the program and then open it again.
If you are still having trouble try to use QPST to check that the device is recognised.
From there double click your device name and it should put a 'tick' next to it.
It should show your device details and the bottom under 'Devices Online:'
From the click on the 'Band' tab.
This will change screens to the band menu.
CMDA/GSM/HSDPA
ALL THE BANDS will show for CDMA/GSM/HSDPA (NOT YOURS)
Down the bottom right change the radio (black circle) to 'RF BC Config' form 'Band Preferred'
Click the Read button and wait 300seconds (demo limitations)
This will show the bands that YOUR DEVICE HAS.
DO NOT ADD MORE BANDS THAN YOU REQUIRE THIS IS HIGHLY DANGEROUS
To enable more bands, simply click the ones you need and then press Write when you are ready.
LTE
Click the 'LTE' tab
ALL THE BANDS will show for LTE (NOT YOURS)
Down the bottom right change the radio (black circle) to 'LTE BC Config LTE #6828'
Click the Read button and wait 300 seconds (demo limitations)
This will show the LTE bands that YOUR DEVICE HAS.
DO NOT ADD MORE BANDS THAN YOU REQUIRE THIS IS HIGHLY DANGEROUS
To enable more bands, simply click the ones you need and then press Write when ready.
For good measure also change the vaules in 'LTE BC Config DIV LTE #6829'
You can now close DFS.
Disable diag mode using the following code
Code:
adb shell
su
echo 0 > /sys/devices/virtual/android_usb/android0/f_diag/func_en
Don't freak out if you loose signal, this is normal. Simply reboot the phone and signal should come back.
Please read bands from the phone again and let me know if they stayed
I tested it using my Sprint M9.
For me I in New Zealand I enabled LTE Bands 3 (1800+) and 28 (700 APT) and WCDMA VIII (800 MHz).
It seems the change was permanent as I rebooted and read it from the phone and it was still there.
I am unable to test as it is still Sim Locked . If someone could help with that, that would be greatly appreciated
I also tested on my GSM M8, but I did not write to it as I have all the bands I need.
Any questions, feel free to ask.
Hopefully this opens up some doors for this device.
Band LTE reference:
Sprint: 2, 4, 12, 25, 41
T-Mobile: 2, 3, 4, 7, 12, and 17
AT&T: 2, 3, 4, 5, 7, 12, 17, and 29
HTC Dev & Unlocked Versions: 2, 3, 4, 5, 7, 12, 13, 17, 29, 30
Cheers
Stifilz
Thanks to all those involved in testing:
@v1rk - confirmed working on Sprint M8

For diag off
Code:
echo 0 > /sys/devices/virtual/android_usb/android0/f_diag/on
Please let me know the results

@v1rk I noticed you answered 'Yes' in the poll. Would you mind sharing your experience with this?
Such as phone model, brand, s-on/s-off etc
You may well be the very first tester (other than myself) and I would be happy to add you to the credits.

Tested on a spare sprint m8 with the sim unlocked. It was fairly simple process but you have to be patient and make sure its copied correctly. I used windows 7 since windows 8.1 & 10 was annoying me a times with driver issues. My m9 is already gsm unlocked so cant really test on that nor can i try on a dev m8 which i got already.

Thanks for the feedback. The idea is that it will WORK on GSM
The f_diag code can enable the diag mode on GSM phones. On CDMA you can use the ##3424# code from phone dialer.
I could read the bands of my GSM M8 but had no need to write to it.
Also tried on a spare GSM M7, but this did no keep the bands that I added / removed after a reboot. Whereas, the M9 kept them changed.
With windows 8 you'll have to disable driver checks etc also. It was such a pain
Thanks again for your input
Stifilz
Are the drivers same for m8?
Worked without any issues at all. Thanks a lot, I needed in order to unlock band 28 700 APT. I'm using an HTC One M9 Unlocked - Developer Edition.
Only thing, I had to reboot my device after doing echo 0 command in order to get signal again.
Thanks again!

Glad to hear. Can you please confirm that the band is still available after the reboot by reading the bands from the phone again? I thought it had worked with my M7 but the bands had changed back after boot. I'm hoping it was an isolated incident
Thanks again, will add you to the credits for testing :good:

Please try the diag drivers from here. I will double check mine later http://forum.xda-developers.com/showthread.php?t=673174

Just checked after a couple of reboots and I can confirm BC 28 is not sticking upon reboot. I tried deselecting another band (BC 29) and adding BC28 thinking maybe there was a maximum limitation of bands HTC One M9 can be capable of handling but it does not change the result. It sticks while it is on and when the phone reboot it resets to its original bands configuration. I can only edit 'LTE BC Config LTE #6828' on DFS and not DIV LTE. I'm running Maximus ROM, S-Off, latest firmware and modem radio.
Hope it helps!
Confirmed Wind works on CM13(Marshmallow) Koodo D852.
Original thread (as far I can tell):
http://forum.xda-developers.com/cro...ad-progress-please-leave-im-updating-t2871269
Thanx & credits to
@olokos, @BlackSoulxxx and others for their hard work.
HOWEVER: I used 115868544 for 1877:RF_BC_CONFIG_I value - GSM(07,08,09,19,21) and WCDMA(22,23,25,26) where WCDMA(25) is for the extra US 1700 band. I also tried with adding WCDMA(50) Japan 1700 band, but the phone would take long to find Wind network, and would lock up when trying to manually set network operator on cellular network settings.

1. Download this zip Google it as it's banned from xda for the ability of imei change
2. Extract it and install QPST from that zip
3. Open the caller app and type in *#*#8778#*#* (it should go off the screen after you type in the last symbol "*"
1. Remove all installed drivers.
2. Install LG United Mobile Driver
3. Enable debugging and install adb driver if it's not automatically installed.
4. Using adb issue the following commands on a separate line
Code:
.
• LGE Android for Diagnostics Port (COM*)
• LGE Android USB Serial Port (COM*)
Note: I only got LGE Android usb serial port
Click to expand...
Click to collapse
-never got step 3 to work, after you enter "setprop sys.usb.config diag,adb" (see below) the adb will exit and windows Device Manager will recognize new port which should be named "LGE AndroidNet USB Serial Port (COM*)" if it shows "LGE Modem USB Serial Port (COM*)" QPST will NOT work (you may need to update driver from LG United Mobile Driver folder)
5. Connect your phone to your PC
6. Open ADB console
7. Type in these commands:
Code:
adb shell
su
setprop sys.usb.config diag,adb
I do not know if you have to do the previous but I had to open hiddenmenu to get diag to work.
• AT&T: 3845#*850#
• Sprint: 5689#*990#
• T-Mobile: 3845#*851#
• Verizon Wireless: ##228378 (+ send)
• International Models: 3845#*855#
On my d852 I used 3845#*852#
Select port setting>diag settings>usb set for diag
Click to expand...
Click to collapse
-on my D852 the hidden menu did not work
14. Press start button and navigate to QPST -> QPST Configuration
15. Go back to device manager -> ports -> LGE Mobile USB Serial Port(Com*)
16. Find "COM*" in my case it was "COM4". It might be different for you.
17. In QPST Configuration click on "Add new port" and in "Port" type in your "COM*". In my case It's "COM4" in there. In Port label it could be anything u want. In my case I used a G3 so I typed IN "G3".
18. It should look like this now.
19. Navigate to QPST/bin and open RV_NV_Manager.exe
20. press on settings -> Comport and choose your COM port.
21. Press on file -> read from phone
22. Wait patiently until it is finished. Now pay attention!
23. Go to line 1877, click it and copy the decimal number on the right side of a programme. right click - copy
24. Go to the place where you extracted the zip from the first step and start mzTool
25. On the left side you will see "Input radix" - press decimal there.
26. On the right side you will see "RF BC CONFIG" paste your previously copied number from the RV_NV_Manager.exe there.
27. You will see now what bands are you able to use on the bottom of the app in "Bit information"
28. Switch tab to "Band Preference (NV Value)"
29. In there select all GSM bands and WCDMA bands. In my case (LG G3 D852) I selected all of GSM (07,08,19,21)and WCDMA(22,23,25,26,49). I wouldn't suggest you to do anyting else in here unless you know what you’re doing.
30. After you're done choosing what bands do you want - copy decimal number from the bottom right
31. Remove all commas from that number ( "," ) so it would be just a bunch of numbers without anything else. for me it was 562950069289344
32. Open RV_NV_Manager.exe from the point you left it (step 23) and paste your new number without commas "," there.
33. Press on write NV and then press on file ->write changed NV to the phone.
34. Open up the terminal emulator on your phone and write there this:
Code:
su
setprop persist.usb.eng 0
go back into hidden menu > Select port setting>data settings>usb set for data
35. Reboot the device and hope you'll have the reception. If you do, hooray!
36. Type in *#*#SERVICE#*#* (*#*#7378423#*#*) to see
I found this guide that helped.

Sounds interesting, dont you think
However this work that you mentioned here is almost nearly the same based on my original works that posted on XDA and quite famous.
So you should credit your friends who worked on this

Hello
It is possible to unlock WCDMA/UMTS BAND 900 on my LG G3 852 ?
Okay so here is the issue I'm facing today. I bought a Sprint Galaxy S5, and I managed to unlock it for domestic use (AT&T). I cannot get an LTE connection because my Qualcomm processor does not have the appropriate bands to use ATT LTE's network.
I read on here that you can write your NV memory to write the firmware and enable these other bands using QPST and QXDM. The issue I'm having though is getting my computer to install the diagnostic driver for COM port. It reads the Modem under modem tab in device manager. Since the computer doesn't think there is a diagnostic port, QPST configuration cannot open a diag port which is what I need. I've been able to successfully put my phone in rndis + DM + modem by using this in emulator,
su
setprop sys.usb.confing_rndis,diag,diag_mdm
Do not type the first _ as it's meant as a space bar, but USE diag_mdm
But there is no indication that any driver has installed, and does not appear in device manager (even with hidden devices shown).
I'm running 6.0.1 CM13 w/twrp recovery with SELINUX set to permissive.
On windows 8
I also noticed that the guide to add frequency bands was written in 2014, I also know that in Lollipop, you needed to enable CP Logging to get it show up.
What I'm wondering is if there is a missing step to properly installing the diag driver, or if Qualcomm/Samsung found other means to activate it.
I noticed that when using EFSPro I can set it to Diagnostic + Modem + adb but I can only read not read/write NV memory
Also I observed when I send the SPC to read the phone with EFSPro, it says
"SPC was accepted by the phone!"
Then followed by.. "SPC was not found".
Then after I close that popup it reads my NV memory, but I can't write.
Is there a method to enable CP logging on CM13 MM and install the diag com port for QPST use? I don't have a stock recovery to enable CP logging through usual means in as I'm using TWRP.

Did you ever solve this? I plan on following the same guide and I too am having this same problem.
Hi all,
I have been having some trouble following a guide on how to add GSM+LTE bands to this device. Specifically, I am struggling to connect to this device in Diagnostic Mode.
I am running Windows 7 x64. I have installed Samsung USB Driver v1.5.45.00. I have tried an updated driver but I seem to have had less issues with this version. I have also tried using Qualcomm USB Drivers For Windows (QD Loader) but when I select this folder to search for an alternative driver instead of the one Windows assignes I have to manually select an *.inf file and the options (HD-USB QDLoader 9XXX) does not make any sense to me which driver is required for my device.
I can run ##DIAG# in the Phone app and bring up PhoneUtil which brings up a menu to select CDMA MODEM / PDA and I have used both with no success. This menu allows me to access RNDIS+DM+MODEM. If I try to use other applications to switch to CP from AP in other USB settings or PDA to MODEM the phone disappears in device manager.
In QPST Configuration I have to untick "Show Serial and USB/QC Diagnostic ports only" to show the port and select the device. If I continue and use Software Download to back up the xQCN (NV memory) file it gets stuck at 12% and gives me an error "Could not Communicate in Diagnostic Mode"
If I use CDMA Workshop to do a backup the files hex just shows 00's and EFS Professionals backup is the same.
I have tried using stock Lollipop 5.0 firmware an enabling CP logging, rooted 5.0, a custom ROM including CM and I am currently running rooted 6.0.1 firmware.
I used Idoneapps paid service to find the SPC for my device but I don't believe there is any equivalent service to enable or disable the bands on my device.
All I can consider is wrong is the possibility of not having the right drivers but I have no idea where to find the right ones. I am at a bit of a dead end, any help would be appreciated.
Thanks.

man, if anyone can shed some light on this, itll breathe some new life into my phone. I looked for the very same thing a while back as i switched to H2O wireless using AT&T towers and its working, but just on HSPA+ and thats because all of the LTE bands arent unlocked on my phone. QXDM and QPST are the tools we need, but the driver issues are whats stopping me too. Anyone with insight would be greatly appreciated
bump
I was having trouble with connecting to B5 ( 850) LTE as I was consonantly connected to 1800... So i searched and searched and managed to unlock bands and now getting B5 850 as the first preference ...Below guide can literally break your phone if you do not follow correctly ...
Code:
#include
/*
* Your warranty is now void.
*
* I am not responsible for bricked devices, dead SD cards,
* do some research if you have any concerns about features included in this ROM
* before flashing it! YOU are choosing to make these modifications, and if
* you point the finger at me for messing up your device, I will run.
*/
1. Make sure your phone is rooted and you have SuperSU installed, ADB drivers installed
2. Download "Setup DFS Studio" from http://cdmatool.com or the DFS Studio 16.05.31.0 (an older version) from here https://mega.nz/#!h1ImHJyK!gBcp2j6wI...YSoIjPkY_hJJVY ( use this - demo will work and do not update / will prompt with mandatory update you can drag that aside)
3. Connect the phone to the computer via USB
4. Select MTP and USB debugging
5. Open command prompt from Start => Run and type "cmd.exe". Once opened, type "adb shell". It should show "[email protected]_x2:/ $"
6. Open the SuperSU app on the phone
7. Type in cmd.exe "su" and grant access of ADB shell in SuperSU, you will see "[email protected]_x2:/ #"
8. Type in cmd.exe "setprop sys.usb.config diag,adb" and your phone will enter into Diagnotics Mode - this means that the MTP connection will be lost (you won't find any portable device in My Computer).
9. The drivers should be installed for the Diag Mode and you can see in Device Manager at Ports - Qualcomm HS-USB Android DIAG 901D (COMxx). ( mine did not come up so i had to plug in to USB 3 port and refresh port list on to very right DFS )
10. At this stage, if all should be well, you can start the "Qualcomm Tool" from DFS Studio folder. You can close the login window and it will run in demo mode (enough for what we need)
11. In the "Main" tab, double click on "Qualcomm HS-USB Android DIAG 901D (COMxx)" to select it - in the DFS log you will see "Qualcomm HS-USB Android DIAG 901D (COMxx) device in diagnostic mode"
12. In DFS Tool select tab "Band"
13. In tab "CDMA/GSM/HSPDA" select "RF BC Config" and then "Read"
14. Select the bands you need and then press "Write"
15. In the same tab, select "Bands Preffered" and do the same as above (read-write)
16. Select "LTE" tab which is aside "CDMA/GSM/HSPDA" and do the same as above. I changed values only in "LTE BC Config #6828" as the "LTE BC Config DIV #6829" didn't work for me when I pressed Read (there was nothing selected, all blank).
17. After operation had been completed, close Qualcomm Tool, unplug the phone and restart it.
Notes:
You must back up Rom( stock or modified stock Turbo alike and the EFS partition( in TWRP) as my first reboot said no sim... With EFS back up phone was back from dead
Credits for this goes to chatmonchy and valy_cta
This works to use x720 on US network?
It seems it would work on 720 as well, given that it opened bands that are officially open on 720 but not on 727 (such as band 20).

Should as I was able to write all available bands, for instance I am using Vodafone which has duplex 1800 but x720 out of box support only one after changes I get both
... Please do not forget to back up ROM (stock or modified stock like Turbo) and EFS partition.
I got my phone into diag mode and but had trouble getting windows 7 to recognize the device. I found an upload of the qualcomm drivers and that fixed it and windows recognized the diag mode correctly as you had said in your post as "Qualcomm HS-USB Android DIAG 901D (COMxx)" I tried DFS but couldn't get it to recognize any com ports or my device. It just has blank lists there. I tried changing the com port on the qualcomm DIAG to com2 just in case but that didn't seem to help. Anyone else having trouble getting the com port recognized by DFS?

Hmm something seemed to be messed up as I didn't have the refresh port dialog box with the version of DFS i had downloaded. I only had "reset" which didn't seem to do anything. I think i ended up downloading the older version and that one worked.

This didn't do anything for me, however i'm also on Lineage OS so I don't know if those codes are ROM specific.
I can however confirm this message works fine for the x720! I was able to unlock LTE bands 17 and 12 confirmed with network signal guru. Thanks for the write up! :laugh:

Glad to contribute...mine could have been windows 10 related and only recognised with Stock ROM with super SU
Any follow up on this? Have you went out into the wild and actually confirmed that the unlocked bands are truly being used and not just -reporting- unlocked? I'm still waiting to hear from someone saying the unlocked bands were actually proven to be in live action usage after being "unlocked".
Mine is working... Try it ur self

Can you please advise where you download the windows 7 driver for Qualcomm HS-USB Android DIAG 901D? Thank you in advance!
When restarting, the value returns to original.
The wcdma band returns to default.
Omg...
Please change the post title which is confusing, you unlocked nothing .... B5 is already unlocked in the phone, all you did, is choose b5 over the other signals as the preferenced one thts it , dont say you unlock stuff when they already are !.... Right now we know that this phone have this hardware for the le x720(i dont know if its same for le x727 but apparently it is) :
SKY77643-21
Hardware allows u to :
WCDMA Bands I, II, III, IV, V, VIII, IX
TD-SCDMA Bands 34, 39
FDD LTE Bands 1, 2, 3, 4, 5, 7, 8, 9, 12, 13, 17, 20, 28, 30
TDD LTE Bands 38, 39, 40, 41
The x720 band are : B1/2/3/4/5/7/8/20/38/39/40/41
The x727 band are : B1/2/3/4/5/7/8/12/17/29/30/38
So maybe try to unlock b28 (hardware compatible) for example or b12 for the le x720 since only the x727 have it and then u can confirm tht u unlock something cause your post and the title are not saying the same.
As with le max 2, modem firms 15S and beyond have restrictions. Even if you change the band, you return to the original.
Japanese guy are making temporary connection possible situations, but it seems to return to the original after restarting.
