Disable Samsung NV values protection? I Googled this, and haven't come with anything note worthy. The NV values do stick after a reboot/power cycle. Not sure if there's anything else specific to verify if protection is disabled. I'm on stock ROM. 4.4.2 or 4.4.4 I think. Sorry, don't have the phone with me right now.

Did you just disable NV protection (how), then write NV Item 6828?

Thanks.
[Sony Cross-Device General] jkjambo:
Can you gave us more details ?

what do you mean in disabling nv values protection?

I have a sprint HTC One m7 which has the 1900, and 2100 mhz already enabled. I want to take my phone to T-Mobile so I need to enable the 850 and 700mhz bands and possibly the AWS band. Is this possible? And what lines do I edit? Thanks!
[Sony Cross-Device General] JellyKitkatLoli:
What values did you use on your M8 exactly?

Honestly I have no clue why this isn't working as the phone's modem is 100% capable of 1800 mhz and 2600 mhz, I might have to try only 1800 MHZ value but I doubt it would help.

Besides that the only value that doesn't screw up my reception when the phones "tries" to get 4G is 528456 which is the only value with bands 3,4,7,13

Thing is it won't go to 4G, highest is H+ but at least I don't lose all bars.

Other than that the original value also "works" goes up to H+ but it won't pick up LTE duh, any other value just causes the loop I've mentioned before.

The first thing to keep in mind is every device has limitations. Now think about what you just said. Once you do that, read the title of this thread. Put it all together and you have your answer.
[Sony Cross-Device General] adryanosss:
[MENTION=4895937]palmbeach05[/MENTION] It's obvious that I have some limitations, but I asked about band 38 because I saw some devices with same chipset like ZTE Nubia X6 with this band activated. That's why I asked.

Has anyone managed to get band 12 working on the Nexus 5 D820?
[Sony Cross-Device General] Starbomba:
I was able to unlock some bands of my SO-04E. I was having issues with the MI_04 driver, but afyter two hours i found [MENTION=3071910]coglyostro[/MENTION] post, used MI_05 and it worked!

The only downside is that i was not able to activate all bands, if i do it my phone gets stuck looking for a signal then reboots. I'm doing a band-by-band test, to see which one is conflicting, though i am not sure if anyone has a list of "unlockable" bands for the SO-04E or the LTE ZR (C5503).

I also want to unlock a Nexus 4, which bands would be the unlockable ones on that one?

Third, can any band be unlocked from an Xperia M (MSM8227)?

Lastly, and this is a bit more for [MENTION=5733862]BlackSoulxxx[/MENTION], were you able to do something about the TV antenna for your SO-04E?
[Sony Cross-Device General] NABENDU1:
Which bands do u need to unlock for nexus 4. As far as I know there's modified modems on XDA for n4 if u are looking at LTE bands
[Sony Cross-Device General] BlackSoulxxx:
Congrats on your success with SO-04E. Normally all GSM/WCDMA band will work, and might some LTE band to0 (this may different per devices)...

On the TV side, I can make the SO-04E to receive non-JP TV signal. But the antenna only receive ISDB-T/Tmm signal (470-806Mhz/207.5-222 MHz) so only Japan, Argentina, Brazil, Chile, Peru and Uruguay can use it.....
[Sony Cross-Device General] Starbomba:
I'm looking mostly for GSM/3G bands as some carriers over here only have the 2G band open. We do not have LTE over here (yet), so i'm not in a hurry to unlock that, that and i know only Band 4 can be truly unlocked. And yes, i have been reading to see if a hybrid modem would suit the phone best in terms of battery duration, but it seems those are mostly for LTE support. As this is the ladies's phone, i don't want to tinker with it too much. :D

Yeah, i wondered the same, but after 5 reboots and over an hour without signal, i decided to reflash back the original bands. After that i have been testing band by band. Some take like 5 minutes to take a signal on my current carrier, but in the end it does. Due to little time i haven't been able to truly test all bands and see which one is the conflicting one.

I want to leave LTE bands 1900MHz, 1700MHz, and 2100MHz open on my SO-04E, as those are the ones planned to be used when we get LTE over here, plus those are the ones i use when i travel, as i go to Argentina, Brazil and Colombia from time to time for work reasons (and that is why i want to unlock the TV antenna as well, as i know those countries adopted the Japanese TV standard).

Too bad i got my S5 before knowing about LTE developments, it is the Exynos version :( Hopefully the S7 is also waterproofed, i don't like the S6 beacuse of that, and the S6 Active is too bulky for my liking. I might also get the S5 LTE-A just for the screen resolution (moar pixels pls :eek:) and bigger RAM in the same format as the regular S5.
[Sony Cross-Device General] mihailgreceanu:
hi, sorry to bother you, wich driver did you used for your xz for modem or diag ? i tried modified htc usb driver but the rv nv and qpst can t read or write, but both see the port (i have apq8064). i really need to add some bands because i came from europe to usa and the phone is not that compattible. thank you
[Sony Cross-Device General] palmbeach05:
You need to find your device's chipset specs. For example, I'm on the Atrix HD, we have the Qualcomm Snapdragon S4, and am on ATT. The Razr HD (Verizon) and Photon Q HD (Sprint) have the same thing. Some bands that the Verizon and Sprint variants have cannot be unlocked or used on my ATT variant.

People i have samsung galaxy s5 sm g906k and I can't unlock bands. Help me please. I do everything according to instructions, but after a reboot all settings are returned to factory settings
[Sony Cross-Device General] AlpineMan:
A few of us have not been able to verify if you can enable additional bands on ANY Samsung Galaxy phone.

You can try switching your phone to permissive mode, then rewrite the NV Item settings again.

But again, even if you're able to do so, I won't be surprised if you won't get any additional LTE bands working.

Xperia Z1S C6916 - Working

For anyone interested, I was able to get this working on my Z1S

My goal was to enable LTE Band 2 (1900) and 12(700) for coverage in T-Mobile's expanded LTE only coverage areas

Details

T-Mobile Xperia Z1S C6916 running Lollipop 5.0.2 build 14.5.B.0.236

Windows 10 with Driver Signature Enforcement turned off

Steps I took

1. Rooted using latest Kingroot - It reported that my device was not compatible but I could try anyway - It worked

2. Replaced Kingroot with SuperSU using Mr.W0lf's method -http://xdaforums.com/showpost.php?p=60936999&postcount=29

3. Followed instructions in this thread with one addition to the ADB shell commands. Not sure how necessary this is, it worked for me

setprop usb.rndis.enable 1

4. Tested by using the Sony Tech Mode to force Band 2 - Unable to test band 12. Will test when in the presence of known band 12 towers

*#*#*386#*#*

EDIT 9/17

Note:

After driver installation(the most important part of this process)

I used QPST to connect to the phone

Then I used QXDM to edit the LTE Fields (6828 and 6829)

I used NV calculator to calculate the new LTE value to enable Bands 2,4,12,17, The value I used was 67594 (please make your own calculations)
[Sony Cross-Device General] kansasboy001:
Can I enable LTE band 12 on msm8974 (snapdragon 800) without damaging band 17 hardware?
[Sony Cross-Device General] palmbeach05:
If you can unlock it, you will be fine
[Sony Cross-Device General] kansasboy001:
Alright! I was able to unlock using qdxm's NV editor. Qpst would not work with my g2.
[Sony Cross-Device General] palmbeach05:
I hear you. Some users reported that either one or the other, or both worked for them. Congrats on getting it unlocked!
[Sony Cross-Device General] kansasboy001:
It seems pointless to use qpst when qxdm is a newer and much better tool.

What I really like about the g2 is that I can backup the efs so I can switch between stock and unlocked values to compare signal
[Sony Cross-Device General] Hnk1:
For verizon, default is 562950035735424

I am not sure if you read the whole thing looking for Lg G2.

you should use this commands from pc

1) adb shell

2) su

3) echo 1 > /sys/devices/platform/lg_diag_cmd/diag_enable

4) setprop sys.usb.config acm,diag,mtp,adb

For using the newer end tool, use this guide

http://xdaforums.com/galaxy-s5/general/how-to-add-rf-lte-frequency-bands-to-t2886059

On verizon G2, this did not work. I ended up without a signal so I reflashed the old decimal code and signals came back. Couldnot add LTE band 3
[Sony Cross-Device General] eldonly:
could u try band38, 39, 40 or 41 and get reception?
[Sony Cross-Device General] kansasboy001:
I did use those commands to enter diag mode. I also followed that guide for the most part although I had to edit the nv values 1877, 441, 946, and 2954 manually using the values created by the nv calculator app with qxdm as qpst gave an error. I was able to unlock LTE band 12 700mhz and WCDMA band 4 1700mhz AWS on my d800 (at&t) I have been able to test the LTE band and it does work. However I am not sure band 4 is working as the search for networks fails when I have aws unlocked, infact it fails if any other wcdma or gsm band is unlocked. If anyone knows anything about editing the baseband to fix this it would be great!
[Sony Cross-Device General] Hnk1:
Cheers for the information. I tried to unlock band 3 (1800Mhz) for my device as well but I couldnot actually as it resulted in NO SIGNALS at all from all providers. However, I didnot try to add JUST band 3 but three four more. Also, I only see 1877, 441, 946 but not 2954 on it.

Do you think, I need to change all three (4 in your case) values or even 1877 would do?

I am also trying to get it unlocked via software by going into hidden menu. You can try that as well.

http://xdaforums.com/verizon-lg-g3/general/unlocked-lte-bands-vs985-t2909150

I was also trying to get my VK810 (Verizon LG G Pad 4g) to work on 1800 Mhz. Still needs some testing
[Sony Cross-Device General] kansasboy001:
You actually do need to edit all 3 NV items. But be careful 441 and 946 are probably in hex format. You can check this my looking in qdxm if it said base 16 or something similar it is hex. The NV value will also probably be written in this format 0x0FFF (where FFF is any other numbers or letters). Also you will need to use the mz tool app from the files on the op of this thread as the nv calculator app doesn't have cdma frequencies. You need to first take your stock 1877 value and put it in mz tool being sure to change mz tool from hex or binary (I can't remember which it has) to decimal. Note all the currently enabled bands and be sure to select ALL of those along with the 1800mhz band you want to enable. At the bottom of the screen of mz tool there will be 4 sets of numbers. The first from the left is your 1877 value. The second is the 411 (this is given in decimal format and probably needs converted to hex format. There are many websites that do this . Qxpt might give a drop down selection menu for this nv. Ignore it and delete the value in the box and enter yours. If it is hex on your vs980 (which I believe it probably is) be sure to enter 0x first then your hex value just as it appears from the hex conversion tool you used. The third value is 946 use the same procedure as for 441 to enter this value. As long as you have efs backups AND are careful to select ALL the originally enabled bands especially the CDMA ones you should be fine. Just remember to select those cdma bands. Sometimes if the CDMA radio is disabled it cannot be re enabled. Good luck!!
[Sony Cross-Device General] Hnk1:
Many thanks for your kind feedback.

Which application do you use for EFS backup ? (I was thinking i could backup my Vk810 as well as there is no dedicated thread for it, although lg g2 has it)

Also, my device which is only 4g supported but I think it has gsm/cdma frequencies as well and my numbers in all these three files are 0

So do you think I can give it a try ?
[Sony Cross-Device General] kansasboy001:
You use twrp. The one with f2fs and thermal control to backup efs. I wouldn't mess with it if it has zero in 1877. You could permanently break cdma.
[Sony Cross-Device General] imboy25:
is there any harm if the procedure failed on my part? planning to do this on my xperia z. and what are the lte bands that you have successfully unlocked (probably in xperia z, too)? thanks!
[Sony Cross-Device General] palmbeach05:
LTE bands are defined by your carrier
[Sony Cross-Device General] Hnk1:
Actually I don't care for cdma at all. My network uses gsm so I am fine with it. I'll report back if I get it to work on gsm , I.e my tablet vk810 (g pad 8.3 lte verizon)

Also, after tinkering with my g2, I had 4g on 27A update but it went away after I flashed lollipop. Seems to me that Verizon has only locked it via a software. (hidden menu is disabled in lollipop as shortcut master can't find it although app manager shows clearly)
[Sony Cross-Device General] kansasboy001:
Have you tried to enable LTE via the nv? And if you don't use CDMA go for it! Actually use this value for 1877: 562950086067072 it should give you GSM and wcdma (h and h+) just about world wide. NV 441 is 896 which would be 0x0380 hex for qdxm. NV 946 is 2024 which would be 0x07E8 for qdxm. You don't have 2954 so well ignore that. Now for LTE a good value would for both NV 6828 and 6829 (enter the same value for both) would be 596063. This should give just about world wide GSM and LTE coverage
[Sony Cross-Device General] imboy25:

And in case something gone wrong an efs backup and a backup in qsdm should be enough to recover my phone to it initial state? Many thanks

Sent from my LG-D801
[Sony Cross-Device General] kansasboy001:
Yes an efs will be enough. The value for 6828 and 6829 for you would be 589839. This keeps your stock LTE bands 2,4,17 and adds 1,3,20. Good luck!

If yes, then I'm able to boot to bootloader.

[Sony Cross-Device General] palmbeach05:
That is correct. You should be in diag mode when you boot to bp tools
[Sony Cross-Device General] moso11:

P.S: I'm using custom ROM so does it make a difference? Should I revert back to stock?
[Sony Cross-Device General] palmbeach05:
You shouldn't need to switch back to stock. Personally, I did this on CM11. BP Tools does seem just like a normal boot. Once it boots up into BP Tools, turn on adb and connect to computer and follow the steps. You should be able to see the phone using the programs now.

So I don't need to perform step 3?

[Sony Cross-Device General] palmbeach05:
I see what device you refer to. Start digging around for specs regarding that chipset in that device. It may or may not be doable. Best advice, if you want this device on your network (still unknown), you need to see if it will have the specs to do so. Like with my chipset family, a gsm phone won't work on a cdma network. Do the research, then ask questions/post results of your tests.
[Sony Cross-Device General] miguelAr52:
