Enable AWS for i337 newer roms (nj4) 4.4.4 - AT&T Samsung Galaxy S 4 General

I have had a few people asking about enabling AWS on the NJ4 baseband running KitKat 4.4.4. I found that the MF3 modem will no longer work with NJ4 builds. After some trial and error and referencing a few threads and getting some direction by a user Product F(RED) I found a method that works for my s4 I337 on the newer roms.
Try this at your own risk there is always the possibility that something could go wrong.
1) BE ROOTED
2) install a app called terminal emulator onto the phone
3) Dial *#0808# on the keypad
4) select RNDIS + DM + MODEM
5) Install QPST Setup 2.7 build 323 on the computer
6) Find the program RF NV Item Manager that was installed when installing QPST and open it(Located in the QPST install folder)
7) Read the values on the phone under the File option(File-Read from phone)
8) look for line 1877 and change the number that reads 82314112 to now show 115868544
line 1877 should now read 115868544
THEN
9) Select FILE and then WRITE CHANGED NV ITEMS TO PHONE.
WAIT FOR A FEW SECONDS WHEN DONE
10) Use terminal emulator to enter command
su
Then enter command
setprop persist.usb.eng 0
then reboot the phone.
done
Root access is needed to do this method as terminal emulator is used. This is the method i used and it worked. I was pointed to a similar method by Product F(RED) and after some trial and error, I came up with a working method using some logical reasoning after reading the thread at "Unlock all bands of your Qualcomm device." I used a stock rom 1st due to the touchwiz enabled capabilities however I changed roms afterwords. Just make sure the new rom of choice don't upgrade the modem

Bookmarked. I have a feeling I may need this in the future. Thanks!

Running the Insane ROM built off the i919 in Safestrap on my i337. Had AWS enabled before updating to 4.4.4 but now I am trying to enable it again and cant run any USSD codes. Just gives me an unable to process error every time.
Any ideas?? Thanks!!

Sorry for the double post but I just booted into the stock rom and did the above method and it seems to unlock the AWS band. Only concern is, will it still be unlocked when I switch back to the ROM SLOT 1 Rom I run daily?

hello,
i cant located the rf nv manager... either in 323 or 411 ver of qpst....also installed qxdm pro and cant find it either? on nj4 4.4.4 also.
thanks!

I only use a single slot but i used a safestrap compatible t-mobile stock rom first to due the edits. Then I loaded the insane kitkat rom by the sickness over the existing rom. The insane rom dont overwrite the modem files so everything was fine.

ok so i got into the rf nv manager.... what is at the end of the command that you type for the terminal emulator? zero or letter o?
thanks!

the number 0

unfortunately this does not work for me.. not sure why. I have WCDMA Preferred enabled.. but the Wind Network doesn't register. I am on a rooted NJ4 Baseband and modem. is there anything else i could look into? its funny my phone worked for months.. then all of a sudden it stopped picking up the Wind Network. hence me trying all of this.. I also updated the ROM to NJ4 just to try this out.

Question, did you keep the NJ4 Modem or did you stick to the MF3 modem but just performed the above steps?

The MF3 modem wouldn't work with 4.4.4 and this is the reason i had to use the NJ4 modem. I wanted to run the 4.4.4 rom. Im on T-mobile and did this just to unlock aws for the full spectrum of the tmobile band.

Has anyone tried this on OC3 modem?

It looks like the OC3 kernel doesn't support the COM port mode that the QPST needs to communicate with. Trying to set it will just be registered as an unknown device in Windows.
You will have to roll back to a Kitkat ROM to use this process. There are already a few reports that the modification persists after upgrading to OC3, and none that say it doesn't.

I Had the same issue.. after I used it once it never let me back in through the dial pad... randomly today I found how to get in and have a nice little UI too lol I was poking around in my app called Phone Info * Samsung* by vndnguyen in the app store you need root access but in the menu it not only shows you all your phones secret codes but if you push other tools it gives you 4 options one is service mode (root) easy UI in Service mode for USSD codes enjoy

Downgrade from 5.0.1?
Just want to confirm, if I downgrade the phone from 5.0.1 what should I downgrade to to enable AWS?

Easy enough to follow. Any way to properly ensure it they have been "activated." I've seen the menus (*#*#4636#*#*, *#0011#, *#2263#, etc...), but I've only seen it show Band 2 850Mhz with 10 Freq. I haven't been to other places in my area yet to see if it changes since I just did this last night. I'm assuming it automatically picks the frequencies to stay on LTE if it's in the area, right?

Ever get an answer to your question? I'm now on a TM MVNO and need 1700 open for LTE.
From US Mobile FAQ
Your data speed depends on what type of phone you are using. Please check your device's specifications to see if your phone offers data features. In order to access the high speed data network, your device must include a 1700/2100 (AWS) frequency band.

when the value is set to 82314112 then *#2263# will not let you select the 1700 WCDMA Band Preference. Once the new value of 115868544 is written to the phone, the option will stick when selected. You most likely wouldn't want to leave it set to 1700 WCDMA but that depends on your situation. Automatic always seems to select the best connection. However a good way to test it would be to
Open the phone pad and dial *#2263#
Select WCDMA Band Preference
Select WCDMA 1700
Hit menu key select back. Make sure the star is on WCDMA 1700. If not, the NV value on line 1877 is most likely still set at 82314112 and not 115868544.
However if the star is set on WCDMA 1700 and you are a subscriber to a provider offering service on that band, you should be picking it up.
Set back to automatic when done.
Tmobile shut down the 1700 band in my area as its all been refarmed. When i was testing it in January 2015 it connected to 1700 no problem.

3G on AT&T (US)

So, I got my Touch Pro from Expansys yesterday, and it is a UK model (based on the fact that it came with a European charging plug)... but, I am curious as to why it will only connect to EDGE on AT&T.
As far as I know, AT&T 3G UMTS (WCDMA) uses the 1900 band. When I go in to the phone, then choose menu->options, then go to the "Band" page there are two drop-downs:
Network Type:
- Auto
- GSM
- WCDMA
GSM/UMTS Band:
- Auto
- GSM(900+1800)+UMTS(2100)
- GSM(1900+850)+UMTS(1900+850)
- UMTS(2100+800)
So, this makes me think that setting the GSM/UMTS band to "Auto" or "GSM(1900+850)+UMTS(1900+850)" would make the Touch Pro connect to AT&T's 3G (1900MHz) ... but, it doesn't.
Ideas?

Verizon HTC One M8 - Global Bands Active/configured

Just wanted to give some info I found using QPST(qualcomm software) to see what cell bands are configured for our HTC One M8. I even looked at the Rezound bands as well. As most of you know, verizon didn't carrier lock our phones, so if we switch to global or even GSM network, we can use other carriers GSM SIM cards. Just need to properly configure the APN's of course. Below are the bands that the phone will search for when Global Network is selected. I pulled this configuration from my actual device. The Rezound only was missing Bit 19 & 49 selection, but everything else was selected:
[Bit_00] Band Class 0, A-System
[Bit_01] Band Class 0, B-System
[Bit_02] Band Class 1, all blocks
[Bit_07] GSM DCS 1800 band
[Bit_08] GSM Extended GSM (E-GSM) band
[Bit_09] GSM Primary GSM (P-GSM) band
[Bit_19] GSM 850 band
[Bit_21] GSM PCS 1900 band
[Bit_22] WCDMA Band I - EUROPE JAPAN & CHINA IMT 2100 band
[Bit_23] WCDMA Band II - US PCS 1900 band
[Bit_26] WCDMA Band V - US 850 band
[Bit_49] WCDMA Band VIII - EUROPE & JAPAN 900 band
I'm guessing the reason some of us are having issues on Tmobile is that the AWS bands are missing? Can we enable them somehow?

It could possibly be activated using QPST, but there are other steps to do it. The only issue is that since QPST is the QualComm radio programing, there is potential to lose signal quality or lose all radio functionality. That said, it could also be possible to recover by flashing the original firmware or RUU to recover. I now T-mobile uses 1900 GSM PCS band and AWS 1700 mHZ. There is another program I use to actually enable more bands. The program basically converts the selection of bands to a hexidecimal number to use in QPST software to program the added bands. Again, not sure if the Qualcom chip can use it. There is a WCDMA band selection for Bit (25) IV- US 1700 than could be programed to enable. I used a thread from the Sony Xperia forum to help me use the two programs.

Nop, if someone can tell me which Rom has the change bands function then can try that as well. But even after opening the bands I'm only able to get H 14.4mbps.

There's a solution for this problem, if you are s-off-ed. I also did the same thing - i selected USA bands and my phone radio died. Just make a nandroid, flash ARHD , go to the same 4636 menu and it will give you another option in band selection - Auto!! Choose auto, then reboot and make sure you have connection with the network. Then restore from nandroid and you're good to go! I will try to find the link to the original thread!

Thanks that was helpful! Somehow I also had recently loaded a Xposed app to show CPU speed on the top bar. I uninstalled that then after two reboots things came back. So odd, but I'm not complaining at this point.
after a google search it seems people have gotten into problems with chaning bands on verizon devices, the above solutions brings the radio back to life. But it certainly doesn't unlock LTE on europe bands.
So i guess its a lost cause, as it must be a hardware limitation
Yeah disappointing that we can't add those

Original thread for unlocking all bands
wow!
good job
was it hard? im afraid...

how would i change frequency band on unlocked phone?

i have a unlocked reddot mobile R50 (pretty sure a chinese clone). its a mtk6572 device with dual sim, rooted and running 4.2.2
gsm bands are 850/900/1800/1900mhz
dual-band 3g WCDMA 850/2100mhz
i'm using an att straight talk sim. i'm getting full bars but only getting edge. according to "mobile radio frequency" i'm on gsm 850. it don't change wherever i go.
so my questions are:
is it supposed to stay on 850 or is it supposed to change depending on where your are?
is there a universal way to change it for example some samsung phones have a hidden service menu via dial code. i've tried all dial codes but don't have a hidden menu.
any way to do it by editing the sim with dfs or something?
any help would be greatly appreciated.

If you don't know how to add GSM / WCDMA / LTE bands to your phone, please refer to this thread. That thread is for S5 model, but the same principle is also applicable for many other phones, e.g. Samsung, LG, Sony, HTC, Nexus...
You also need some NV editor software (e.g. QPST, QXDM, EFS Professional...) on the PC to write these NV items to your phone.
>> NV items description:
- Adding GSM / WCDMA bands:
NV 01877 - RF Band Configuration
NV 00441 - Band Class Preference
NV 00946 - Expand Band Preference 16 to 32 Bits
NV 02954 - Bits 32 to 63 of Band Preference
- Adding LTE bands:
NV 06828 - LTE BC Configuration
NV 06829 - LTE BC Configuration DIV
DOWNLOAD: https://play.google.com/store/apps/details?id=org.vndnguyen.nvcalc
reserved
This app can show the calculation result in 3 formats: Decimal, Hexadecimal and Byte-swapped Hex.
Update v1.0.5:
- Fix UI issue on some devices.
- Add separate notation settings for GSM/WCDMA and LTE calculation. You should not change the default settings unless you know what you are doing.
I'm intersted in Qualcomm NV access, but not for cell band issues. There appear to be GPS issues with some Samsung phones, and there is some indication that those issues are related to a NV "privacy flag". Apparently older ROMs can turn this bit on and off, but newer ROMs don't - whatever value was left there is "stranded" there. There are people flashing back to CM10.x, setting this bit, then flashing back to CM11. I'm presuming that what is really happening is that they're tweaking this on NV location.
If we could simply read the NV location, we could compare its value to GPS functionality, and see if this is really the issue.
If the above is true, and if we could simply write this one NV location, we'd have a heck of a lot simpler GPS fix.
Thanks, vndnguyen, for your app. And it would be very nice if you add CDMA bands to your app. Thanks again.
if i am interested in enabling umts bands in somewhat old msm7227a based motorola, running gb 2.3.7, with no custom recovery, no custom roms or anything, but rooted.
should i even try?
thanks for making this, i wonder if my Snapdragon 600 on LG G Pro E988 can use this to enable China's TD WCDMA and TD LTE, since FDD is kinda different than TDD

Got a question. I found a discrepancy in your calculator.... Your NV calculator values do not match the NV value of the LTE bands my phone already has. So, how can I trust the calculator to give me correct values for additional bands I wish to enable?
It's at the bottom of this post, but I am putting a lot of information about my phone first, so you know the whole situation.
I have 5.2" 1440p, 3GB RAM Moto Maxx (XT1225), which has Snapdragon 805 -- same as the (Motorola) Nexus 6. In fact it was being tested by Google to be the Nexus 6 (or a Nexus 6 variant) as late as mid-August -- but Google decided to go with the larger size variant and only the larger size variant.
Motorola re-purposed this phone as the Verizon Droid Turbo (XT1254) in the USA and as the Moto Maxx (XT1225) now being sold in a handful of Latin America countries. We already have root, TWRP recovery.
When this phone was being tested by the FCC, it had these LTE bands:
But now being sold as the Moto Maxx (SAME FCC ID number), Motorola enabled more GSM bands and changed one of the LTE bands.
They disabled LTE band 5 (a minor AT&T LTE band), and enabled LTE band 3 (which is used more in Latin America countries).
QPST confirms the 2G/3G bands Motorola now claims for this phone:
Which means the LTE bands they now claim (2, 3, 4, 7, 17) are also probably correct.
Again this phone has the SAME FCC ID NUMBER. And as it's being sold in Puerto Rico (U.S. territory), that is very important. That means there's been no hardware change since U.S. FCC certification -- only software change.
Motorola also promises it has the SAME HARDWARE (including antenna) that the Droid Turbo (XT1254) has (even though the Droid Turbo has a different FCC ID number):
This is also important. It means really, Motorola could not sell the Moto Maxx (XT1225) in Puerto Rico (U.S. territory) under that FCC ID number if any radio-specific hardware had been changed at all.
Thus, we know the additional GSM bands, change in the LTE bands by Motorola was software modem change.
With me so far?
___________________________
Now the discrepancy...
In QXDM NV browser, in Line 6828, the XT1225 phone showed a value of 65630 (for LTE bands 2, 3, 4, 7, 17).
Yet, according to your app, with THESE LTE BANDS enabled (2,3,4,7,17)...
it should be THIS value: 65614.
Now I admit that's CLOSE, but it's not the same.
Therefore, how do I trust the calculator to let me enable MORE bands if this default number does not match in your calculator?
I have edited the values of that line to theoretically enable more LTE bands, but if the beginning number from the phone does not match what your calculator number says, then what exactly have I enabled?

Thank you for your patience for a such long post
But the problem was too simple.
Code:
If supporting LTE Bands are [COLOR="Blue"]2, 4, 5, 7, 17[/COLOR]:
NV 6828 = [COLOR="Red"]65,626[/COLOR]
If supporting LTE Bands are [COLOR="Blue"]2, 3, 4, 7, 17[/COLOR]:
NV 6828 = [COLOR="Red"]65,614[/COLOR]
If supporting LTE Bands are [COLOR="Blue"]2, 3, 4, 5, 7, 17[/COLOR]:
NV 6828 = [COLOR="Red"]65,630[/COLOR]
I don't how how many bands does your phone support. But if the value of NV 6828 in the QXDM NV browser is 65,630, that phone should support the following bands: 2, 3, 4, 5, 7, 17.
There is NO discrepancy here.

So, you are saying the phone supports LTE band 5 out of the box, even though Moto only lists 2,3,4,7,17 on the retail specs?
That after FCC testing they only enabled additional LTE Band 3, but did not disable LTE band 5?
If so, that's interesting.
Only to get you correct: this mod is only to extend the range of usable LTE/GSM bands for roaming, not to extend your connectivity while using your default provider in your home country (e.g. to get better coverage in areas where your default provider has a low signal strenght), right?

Or when changing from one carrier to another in the same country. Many carriers lock down bands the phone could receive, because they want the phone to only be used on their network.
Okay so I'm not really understanding the whole idea behind this. I have a Sony Xperia Z(C6603) and my phone already supports the LTE bands(LTE_BC1, LTE_BC3, LTE_BC5, LTE_BC7, LTE_BC8, LTE_BC20). My problem is that by default my phone and service provider should be able to have LTE working since my service provider also supports LTE band 4 and 7 on their network but upon choosing LTE network modes it has no reception at all, only 3G and HSPA. So I'm assuming I need to do additional unlocking here on my end for my phone but am not really sure why.
I'm able to access through the hidden menu of *#*#4636#*#* and change radio bands and network modes:
But I haven't changed the radio band and tested it yet because I don't know what the outcome will be and if there are any risks or hard bricking of it and don't know how to revert back to default. My service provider's network supports LTE band 4(2100MHz) and band 7(2600MHz). Would I need to go through QXDM to have these 2 frequencies enabled on my phone? Because I noticed how from the radio band list of my phone shows Euro Band which ends up to be 2600MHz but I'm not sure if that's how to enable LTE because it's Euro radio band. Am I okay as it is with my phone's default radio band and just unlock band 4 and 7 somehow through QXDM? Sorry I'm just really clueless and don't want to risk hard bricking my one and only phone.

Your provider supports LTE bands 4 and 7. Of those two, your phone can receive LTE band 7, but you don't see it. Are you sure LTE band 7 is in your area?
My carrier supports five different LTE bands (and my phone can receive them all), but in my area I only see two of those LTE bands. The others are not used in this area by my carrier (AT&T).

Yeah my carrier supports band 4 and 7 in my area, the towers are everywhere.
I checked it using this website: http://www.ertyu.org/steven_nikkel/cancellsites.html
both 2100/2600 are within all the cellular towers in my area.
edit: so if I'm able to choose LTE network mode on my phone, does that mean the LTE network mode consists of all these frequencies of LTE_BC1, LTE_BC3, LTE_BC5, LTE_BC7, LTE_BC8, LTE_BC20? So everytime I change to LTE only or LTE/GSM etc etc, automatically my phone has 2100MHz and 2600MHz included? Which means I don't need QXDM to unlock anything further? It might just be a sim card defect or something maybe. Sorry I'm just trying to understand more
Hi
I am trying to use a US note 3 (n900a) on Europe, but I frequently lose connectivity (although bars are full). The only solution I found is to fix wcdma to 2100 freq, however this also means that I lose reception when there is only GSM coverage.
This app seems to be the ultimate solution for me to calculate a custom NV for GSM+wcdma2100. Am I right?
If so, may I use a NV writer without a box, by just using my usb cable?
Thanks a lot

Best LG G Pro 2 (model) for T-Mobile LTE

I brought back a Pro 2 F350L from Korea because it was listed in swappa as the Att device unlocked. I took it to T-Mobile put in a sim card which automatically chose the appropriate apns. I only get 3g no lte. I have scoured the web and these forums but cant find the info that tells me wether i got the wrong device for Tmo bands. I need help either configuring the correct bands or correct radio to flash or if this device won't or can't get lte on Tmo network. I am more than happy to reward the parties or person who helps me figure out this problem. If i have the wrong phone then so be it i will get the other model (that gets tmo lte) and unload this F350L. Thanks for any and all help.
In network mode, do you have GSM/WCDMA/LTA auto to select, or just GSM/WCDMA auto?

Looks like you have the wrong phone ... https://support.t-mobile.com/message/435224#435224
Bottom line, for optimal utility a T-Mobile phone needs to be:
1. Quad-band GSM
2. HSPA+ on at least band 2, band 4 & band 1 (2100) for roaming.
3. LTE on bands 1, 2, 4 & 12.

So seeing the bands I posted would the phone work for ATT? Thats a huge question because it (350L) is posted on Swappa a a ATT phone? At least I can unload it there, LOL.

"AT&T 4G HSPA and HSPA+ use 850Mhz(Band 5) and 1900Mhz(Band 2) bands but it all depends on area if they own a license. LTE uses Band 17(700Mhz), Band 5(850Mhz), Band 2(1900Mhz), Band 4(1700/2100Mhz) currently."

wiseguyy, I believe the phone must have band 2 and/or 4 for it to utilize TMO's LTE service. From what I've read, band 1 is used only for roaming. Read the entire thread you quoted above.
