Enable AWS band (3g/4g Tmobile) on ATT Note 2 stock baseband

Method 1:
Easiest method to enable AWS and DC HSPA (42Mbps) is to restore the attached qcn backup on ATT note 2. Use software download tool in QPST to restore the attached qcn file.
Restoring qcn will not change your imei, so be worry free and restore Thanks to TEKHD for sharing the T889 qcn backup.
If you face issues with data rate and stability, restore your device original qcn on top and change the value of 01877 to 115868544 in NV browser of QXDM or use 80 03 E8 06 in the text file and write it to device. DC HSPA or 42 Mbps will be disabled after this
Thanks to Arrio for helping me remove imei from qcn file. I have attached my note 2 qcn backup.
Now it should be piece of cake for all
How to posted by Joogle
1. Download and Install QPST, version 2.7 build 374 or higher
2. Go to hidden menu on phone, dial *#7284#
3. Once in Menu choose the option for USBSettingsMenu, then choose the option RNDIS+DM+MODEM.
4. Hook up the phone to the PC via USB at this time if you haven't already. This option works on STOCK TOUCHWIZ.
5. Go to your PC Control Panel. We need to get into the Device Manager to determine where your phone is being recognized as far as the COM ports. For this, go to System -> Device Manager (on the left) or System -> Hardware -> Device Manager (depends on your Control Panel setup). Anyways, scroll down to Ports (may say Ports & LTP, Serial, depends on version). Anyways, find your phone under it, and take note of the COM# (mine was COM9, yours can and probably will vary). If you have exclamation marks anywhere then install the Samsung drivers and try again.
6. Now go to Start Menu -> All Programs -> QPST -> QPST Configuration
7. Click on the Ports tab. Click on Add New Port, then add your Port# where it says Port and name it something you can remember. Hit OK.
8. Now click on Start Clients -> Software Download. Click on the Backup tab. Make sure your phone is listed under Port. If its not, hit Browse, choose the COM that is your phone, and hit OK. Now where it says QCN File, hit Browse, find a safe spot to store your backup on your PC, and name it. Hit OK. Now hit Start. Make sure backup gets to 100% with no errors.
9. Go back into QPST. Go to Start Clients -> Software Download. Click on the Restore tab. Make sure your phone is listed under Port. If not, browse to the appropriate COM port.
10. Choose the QCN backup in the first post of this thread. Click Start, let it finish. Phone should reboot. If it fails rebooting, just do a manual reboot. First boot will take a bit, let it do its thing.
Messing with NV parameters can brick your device.

Does that mean if we enable NV's (which basically enables AWS), we wont be able to disable AWS and go back to At&t GSM or ? Or once we enable NV we can use both at&t and T-Mobile Sims?
Also have you tested this method with T-Mobile SIM? High data speed, low data speed?
I would love to be able to use my Note with AWS band network (Wind mobile in Canada), but instructions are way beyond my understanding :laugh:. Will wait for easier instructions if they get posted.
Thanks for your work.

That's as easy as it gets, and yes it will unlock those bands permanently along side the AT&T bands.

Follow up Qs
1) Thank you so much for posting how to do this.
2) Yeah, I second ruinkhan; Do you know if AWS is still 21mbps or 42mbps like the T889?
3) Is enabling AWS on the N7100 or N7105 possible? How about on CDMA models with SIM slots and GSM support unlocked (such as Verizon i605 or US Cellular R950)?

Use of AWS can be disabled by changing one of the NV item, but all enabled parameters remain active. This does not cause any problem with the device working. It would work as any stock ATT note 2.
Yes you can use any SIM or network that support these radio bands (UMTS 1,2,4,5 and Quad band GSM)
I am using a T-Mobile sim and I do get around 8 Mbps download speed and 3 to 4 Mbps upload.
Ya I agree the instruction are bit complicated

I am working on 42 Mbps, with the posted NV backup, even 42 Mbps NV items are included. My note 2 does inform network about 42 Mbps support when enabled but I dont see any change in download speed. I guess the network does not like something.
Yes it should be possible on N7100 or N7105, as all have the same Qualcomm 9215 baseband chip. But I am not sure if they have the right RF related hardware.

the instructions for nv backup says to select rmnet+dm+modem. i do not see that option in there. are you suppose to choose a different option for the note 2? any issues of doing this on a canadian i317m?
thanks

On my ATT Note 2 I can see that option, what options do you see?

I will do this tonight with my I317, can anyone post a more clear set of instructions? I already have the T-Mobile ROM posted on the AT&T dev section as well as the AT&T ROM on T-Mobile's dev section... This is a huge discovery... I mean huge... Please, anyone care to elaborate on this... Better instructions... I have both the T889 and the I317... And I will test this as soon as there is a better guide... Thank you

Indeed this a huge plus for our At&t Note. I wasnt expecting this to be done this early, but the man did it. My hands are now itching to try this and save $50 a month by switching to AWS network. I would really love to see easier instructions [not all of us hackers ]

Yes you can select any mode with DM (Diag mode) which enables the diagnostic port to the baseband.

It allows people that have At&t Note 2 to use their device with T-Mobile's 1700 frequency band (or 2100 if there is).
In Canada its a big big plus as it allows people like me to be:
1.Free from 3 year contract
2.Have a GSM phone that can be used with AWS network as well.
3.Get a $40 Unlimited Voice/Text/Unlimited Data (10 data cap lol) plan. Of course No LTE or 42mbps speeds.

sjravi, perhaps these NV backups would be of interest for comparison purposes. I got these in the course of trying to flash back the stock modem on my T889V, which it currently bootloops with.
My phone is currently stuck with the I317M modem, has 850, 1900 and AWS HSPA in addition to LTE. Barring any inaccuracies in the Ookla Speedtest app, it also has DC-HSPA. (The phone clocked at 26 Mbps on HSPA during one of my tests.)
There's a stock T-Mobile T889, stock Videotron T889V and my post-repair, I317M modem-running T889V backup in there.

is there list? as in what lines to change?

Things needed:
1> NV back up tool from this post: http://forum.xda-developers.com/showthread.php?t=1804117
2> NV backup from my note 2 attached in this post (without IMEI: nv item 550)
3> NV backup of your device
Its also good to take NV backup using QPST tool before changing anything on the device.
First take a NV backup of your device using the tool mentioned above. NV parameters from 0 to 7225 are needed.
Compare NV param file in this post with your device's to find the needed NV parameters for AWS.( I do not have original NV backup of my device else I would have posted the list. If someone is interested to make a list, it can be added to the post.)
Before restoring nv backup, the AWS NV parameters should to be enabled/B]
The additional NV's that are needed, to enable AWS band are disable/not present and the nv tool does not write these even if the restore file has them. This is what I noticed when I tried to restore. So had to enable all the required parameters using NV browser in QXDM.
Once the NV's are enabled, it cannot be disabled so be careful.
To enable just select the NV item and click write in NV browser and this has to be done for all the needed nv parameters.
Does anybody know a work around to avoid this manual work?
Once all the parameters are enabled the NV file in this post can be restored on to your device to enable AWS.
Messing with NV parameters can brick your device.

NV manager is very old tool and not supported by note 2, so you cannot use it.
Use NV browser in QXDM (last version found online 3.12.724), which you can google to get it.
Once you have installed it. Run QXDM professional
Go to Options > Communications: Here you should see 2 ports for the phone one is modem port and the other diagnostic port.
Select diagnostic port. Check out the attached screenshots
After you have the NV browser open. Select the NV item that needs to be enabled and click "write" this will write the value "0". Hope this helps.

One V CDMA - Problem in enabling data connection

I am using a HTC One V CDMA (Virgin Mobile USA) in India on Reliance CDMA network. The phone was flashed to Reliance and everything is working fine ie I can make/receive calls/sms etc. 1x / EVDO credentials have already been written to the phone.
Now the issue is that I am not able to enable data or the data connection doesn't get enabled automatically. When I try to enable data it says "Disconnected because service is unavailable". But if I press the "Activate this device" button in the settings section, an activation screen 1..2..3 comes up, then wait for 3-4 sec, the 3G symbol gets displayed meaning its able to make a data connection. Now if I go back to the settings page and enable data it successfully connects, and I am able to access internet at EVDO speeds. But after some idle time, the data connection is automatically disconnected and to reconnect I need to repeat the above process. Even if I intentionally disconnect data and try to reconnect, it doesn't happen and I need to go through the "Activate this device" process.
I believe some sort of initialization is missing which is done during the "Activate this device" phase and hence I am able to connect. What could be the reason for this? Is it some setting/configuration that needs to be enabled?
Please pour your valuable tips to resolve this issue.
Thanks

Fixed the issue with auto connection of data, not sure what fixed it exactly, but here are the last changes that I made after which it started working.
You need to use the tool QPST (I used version 2.7.378, an older version didn't work) for this.
In the M.IP tab, disable all profiles except profile 1
Then edit profile 1 and make changes (check attachment)
Then in RmNet tab enable auto connect for device 0 and 1.
After that
PPP Config --> Um --> Enter user/pass as "net" (Req Pw enc should be unchecked)
PPP Config --> AN --> Enter the EVDO credentials given by the MEID registrar (Req Pw enc should be unchecked)
Please note that I got it working merely by trial and error and some of the above changes may not be required and I am not even sure why they are necessary , but with the above configuration I am able to enable data without any problem.

Well, I had loaded the NVDump earlier, but as I had mentioned it would connect first but if you disconnect or get disconnected it wouldn't reconnect.
Check if the SPC is correct, cause I never got any error like that.

You are talking about Reliance CDMA right?
If yes you need to get the MEID registered, will cost you about Rs 500. Reliance store guys will not do it, have to get it done through some 3rd party provider.

Hello varkey bhai,
Please Help me with the problem.
1. my meid is registered with reliance.
2. my prl is 00005
3. i am using the handset since 10 months.
4. evdo is also activated on my number.
But i am just getting 1x speeds.
Only thing i feel, i am missing out is on the username,Password,NV file,akey etc.
I have not received the above details from my reigstrar
Can u please guide me how this can be done to start evdo speeds.
Thanks in advance

Without the correct EVDO credentials, you won't be able to get EVDO speeds. You need to check with your MEID registrar.
NV dump is not really required and the same can be configured manually if you have the credentials as I have described above. Since you are able to make and receive calls, it looks like the Akey is already set.

so that means if i dont get the credentials from the registrar EVDO can never be started on this handset??

You could check with some other person who does MEID registration, maybe they can retrieve the credentials. But without it, EVDO will not work.

I don't think that would be a problem.
Make sure you are using the right PRL file.

No above steps required.
You must have flashed NV Dump already.
Your phone must be activated via *228 already.
Just perform below mentioned steps :
1) Put your phone in Diag Mode by dialing ##3424#
2) Get HTC Diag Mode driver if you don't have it already
3) Download DFS Demo version from DFS Website
4) Connect your phone with DFS, send SPC
5) Now, go to Programming tab -> Data ->
6) Click Read
7) At PPP tab, write "net" (without quotes) to SIP NAI, UID, Pwd field.
Restart the device and here you go, your device would get connected to internet instantly.

[Q] LU6200 - GPRS only, No EDGE/2G Mode

sorry if i posted this in the wrong section
i have LU6200 with sphinx v2 rom
3G is working fine, the problem is when i am indoor i can't get 3G signal so i turn 2G only on
but the signal is G not 2G or E. Which mean it is GPRS signal and it is very slow.
Is there any way so my device got EDGE/2G so when i'm indoor i still get some reliable connection than GPRS??
thanks.

I DONT TAKE NO RESPONSIBILITY IF YOU BRICK YOUR DEVICE.
BACK UP YOUR NV-RAM AND ANYTHING ELSE BEFORE YOU CHANGE ANYTHING.
You have to change the NV item id 2508. (you should have the value 00 which must be changed to 01)
The NV-ITEMS 2509 - 2511 should be also checked. But in my case they were set correctly.
I would use the EFS Explorer from QPST. (Have done it for a L-01D the japanese variant of the p930)
You have to enable DIAG mode on your phone with a script like in http://pastebin.com/rGE7rwSc
to able to connect your phone in QPST.

Extract it and install QPST from that zip
Boot your Moto into bootloader by powering off, then hold Vol+ and Vol- while you power on
Select BP Tools by pressing volume down, then press volume up when hovering over BP Tools
Phone will reboot in diag mode (Nothing will look different in phones UI)
Make sure USB debugging is OFF
Go to device manager and make sure Motorola QC Diag is installed. If not go here http://forum.xda-developers.com/show...76&postcount=3
Find "COM*" in my case it was "COM100". It might be different for you.
Press start button and navigate to QPST -> QPST Configuration.
In QPST Configuration click on "Add new port" and in "Port" type in your "COM*". In my case It's "COM100" in there.
Navigate to QPST/bin and open RF_NV_Manager.exe *(C:\Program Files (x86)\Qualcomm\QPST\bin)
press on settings -> Comport and choose your COM port.
Press on file -> read from phone
Wait patiently until it is finished. Now pay attention!
Go to line 1877, click it and copy the decimal number on the right side of a programme. right click - copy
Go to the place where you extracted the zip and start mzTool
On the left side you will see "Input radix" - press decimal there.
On the right side you will see "RF BC CONFIG" paste your previously copied number from the RF_NV_Manager.exe there.
You will see now what bands are you able to use on the bottom of the app in "Bit information"
Switch tab to "Band Preference (NV Value)"
In there select all GSM bands and WCDMA bands you want to unlock but Make sure to check your original bands before you add more!
After you're done choosing what bands do you want - copy decimal number from the bottom right
Remove all commas from that number ( "," ) so it would be just a bunch of numbers without anything else.
Open RV_NV_Manager.exe from the point you left it and paste your new number without commas "," there.
Press on write NV and then press on file ->write changed NV to the phone.
Reboot the phone you are Done

i'm a bit lost here, it's just unlock GSM & WCDMA bands? not LTE Bands? do you unlock LTE 1800 MHz and 900 MHz frequencies? can you post your phone screenshot after using this mod?

you may try this n post result when i got back 'll check LTE currently where i m no LTE
make sure you have running QPST server
Google for QXDM
Open QXDM, go to Option -> Communication
In Target port, choose your phone com port and press OK
Now in View -> NV Browser
QXDM will open new window, in Category Filter choose LTE
Scroll to id 06828 and click on that, click read then in Input and Value change the value to "1904863"

changed parameter in QXDMA.
Phone still cant find LTE (testes on LTE sim ofc).
My operator uses LTE 2600 MHz (Band 7, B7) and LTE 800 MHz (Band 20, B20)

So sorry Im a total noob to this, but I need to unlock my phone asap, as i was before I had to reflash it due to boot looping issue. Now I cant connect to my Straight talk account/att towers using the SIM card and phone that has always worked for me since I bought it unlocked. Main problem I am having is step 5. "Make sure USB Debugging is OFF" As soon as i turn off the USB debugging the Motorola QC port (COM3 for me) disappears. I left it on so the com port would be active, followed all the steps and still no service. PLEASE HELP and I dont mind paying someone for their assistance if we get my phone working. THANKS!!!

I've tried enabling LTE as described and I'm still testing the results. I need to enable B20 band (800mhz), right now as you know the Razr M may only use the B13 band (700mhz).
That is what I've learned so far:
You'll have to install both QPST (unable to change the LTE bands) and QXDM (able to change the LTE bands, but needs QPST to get installed). Once you have the program installed, reboot the phone in bootloader mode and select BP Tools. Let the phone reboot, then disable USB debugging and connect the phone to the PC. Wait for the device to be installed, if something goes wrong install the driver manually (https://www.youtube.com/watch?v=mm2NKdXdHnc). After this, open QXDM Professional and select the right COM port (the one that's being used by your device) under "options" "communication". Change the "view" field to "NV browser" and "category filter" to "LTE". at this point you could READ the interested fields (06828 and 06829). Calculate the right code to activate the right bands (http://forum.xda-developers.com/galaxy-s5/general/how-to-add-rf-lte-frequency-bands-to-t2886059), change the fields and press WRITE. Power off your phone and reboot: you have chnged the LTE bands.
Now... as said the default value is 4096 (1000000000000 in binary, meaning that the band 13 is the only one usable). In this case the phone may switch from GSM/WCDMA to LTE (settings -> network setting -> preferred network) but clearly is unable to find the network (no signal).
I've changed this parameter to 524288 (10000000000000000000, only B20 band active): the phone works normally but when you select LTE in preferred network the phone doesn' switch and remain in GSM/WCDMA.
Then I've reverted to the initial value (4096): one again everything worked as stated above.
At this point I've tried to activate both the original B13 band and the B20 band, using the parameter 528384: with this setting the phone is able to switch regularly to LTE, but I don't know if the B20 band is active because where I am now there is no LTE signal. I'll try to test the phone during the next days.
Is there a way to check which bands are actually active on the phone (some code, an app, a PC software)?

I've upgraded my sim to a 4G version, then I tried my Razr M in two cities with 4G coverage: no signal. If I put my 4G sim in a Lumia 1020 I can surf on 4G without problem. There's something else we have to change to get the 4G fully working. Maybe examining the modem of a XT905 (Australian version of the Droid Razr M) may give us some clue? The XT905 should be identical in hardware, but uses LTE band 3(1800) and 7(2600) instead of 13(700).
What do you say? Any ideas?

Unfortunately, no. http://forum.xda-developers.com/showthread.php?p=59365798
Sorry, guys, no new LTE bands with this method.

I unlocked my GSM bands with another method I found on here somewhere. It's a lot easier. If you're using cm12.1 you can use a terminal emulator and type sudo unlock us-gsm and it will preform the NV edit automatically.

Thanks for the mention and keeping my original files! I'll link your thread to mine

I would like to know if someone was successfully able to use band 3 (LTE 1800 Mhz) on an MSM8960 device. I have a Droid Razr HD Maxx (XT926M) and it uses the same 'chipset'. So, this thread is quite relevant to me.

Do you guys think this tutorial will work with moto g 3° generation? If you think so, i will try it in my home as soon as i get there and will post the results.
The processor model is Qualcomm MSM8916 Snapdragon 410 quad core.
Your processor model is Qualcomm MSM8960 Snapdragon S4 Plus
Thanks!

very good

Could you fix it?

cannot get LTE communication with S4mini plus (i9195i)

Hello
Here is my issue: I buy a second hand S4 mini plus (i9195i - serrannoveltexx) for its compact size and by considering the simple usage I make of my phone. So far I do not use so much data so I don't care about used network, but recently I start using more data and I notice I never get LTE. I change carrier because I was thinking LTE-cover was the problem, but not. I still have no LTE. So below, is more or less everything I tested:
at beginning, I was few months on stockrom. Then I go to LineageOs 14.1 (thank to dev for the work). In both case I'm almost sure I had no LTE (I checked APN and 4g/3g/2g enable in network menu. And I start to check LTE-cover of each carrier . And I very start to check band used by the different carrier).
I change carrier and I check APN once more : still no LTE.
I come back to stockrom (just in case) : still no LTE
I switch SIM card : my sim card in Oneplus One get LTE and sim-card of my friend do not get LTE with my phone. (So I try copying manually the exact same APN : not working)
I try to flash old stockrom and let OTA update make the work : no LTE
I make necessary to have CSC=XEF as I am in France.
I try flash with pit-file and re-partition.
At the end, the best thing I succes to get was H+ (and for some reason I have it when I clear and restore the NV in 'service menu'), so :
-I contact samsung and they recommend me to go to one of their after-sales office.
-I contact my seller and he tells me that LTE works in germany.
Does someone has an idea how to solve this issue ? something that could block LTE ?
Next step I have in mind :
-I read some topic where double-flash within wipe and clear factory could help (but I have the feeling that will not work because it is more or less what have done to change CSC)
-I would check the activated LTE bands (but in 'service menu', I find a LTE band hexa-value that meet with explanation of binary description (another thread in XDA - thanks to people who write this tuto))
-I am considering go back to LineageOS but 15.
-I am considering to change LTE antenna (this is part of middle frame - I notice if I enable Data when i have 'service menu' opened, the phone seems to looking for LTE first, so I am not sure this is only SW problem ... do you think it is possible that only LTE part of such a SystemOnChip could die ?)
Thank by advance for your help
Best regards

Some older Samsungs eg Note 1 had reception problems due to poor connection (possibly oxidised contacts) that could be fixed by simply tightening the screw a fraction that secures the pcb or antenna so it was grounded (from memory) properly, though of course it could be your actual antenna that has failed. (possible cleaning contacts might be worth a shot if tweaking screw doesn't fix)
(or modem/baseband issue if software, try flash again or try another version, backup your baseband radio settings first with twrp or an app)
edit: also try reset network settings before paying for new antenna (edit: though suppose flash with pit etc should have done this)

Hello,
Some news on the topic:
I try to tighten the screw and I also try to clean LTE antenna contacts : I use very very thin sandpaper (usually used to polish) to be sure there is no oxidation
I also make the mistake to erase all EFSs and EFS_Backup
Reminder : in service menu (*#0011#), then 'UE Setting & Info' / 'Setting' / 'System' / 'NV backup test' / 'Erase all EFS 1/2/3' => So never do this if you have no backup
After this, I lost my IMEI... no way to restore it with IMEI tool... What a pity because I was hoping to only set my IMEI in order to test with completely clear EFS. Finally I restore my IMEI thank to my very first TWRP backup (thank to TWRP team that it works for me because it seems not always the case)
I try 3 times consecutive reset factory : 2 in recovery and 1 in settings.
I try to activate new LTE band but it seems that as I am in StockRom, update is not properly done.
In fact just after the work with QSPT and QXDM, I can find the nez band in service menu (*#0011#), then 'UE Setting & Info' / 'Setting' / 'System' / 'LTE band & CA combination. but after reboot I lose it. Probably I'll make the work one more time after coming back to LineageOS.
One last thing I want to try is going in front of 4G antenna and check signal power seen by the phone but I'm thinking this is not the true problem. I explain:
service menu (*#0011#) start to show Basic network information and if I force LTE_only (in service menu), I can observe these information. strange thing I see are sometime state goes to 'TAU_init' (and also 'deregistr' or 'register'). Some other time MCC-MNC goes to 151515-1515. I have the feeling the phone is trying to connect but something goes wrong and I do not know what...
if someone has an idea, I am still looking for.
Best regards
