Those of you with htc one M7's Which drivers did you use to enable diag mode?
[Sony Cross-Device General] oksagi:
official HTC drivers

You should switch the device to DIAG mode by:

adb shell

su

setprop sys.usb.diag.config diagon
[Sony Cross-Device General] tjsooley:
I am now at the point as the other m7 owners.

The 1877 line does not stick. I wonder if the data from mztool is accurate for the m7. we need someone with a t-mobile htc one m7 post their data for the 1877 field
[Sony Cross-Device General] tjsooley:
Does anyone have the latest version of QXDM?

---------- Post added at 08:07 AM ---------- Previous post was at 07:26 AM ----------

M7 att got a nv backup with qpst from a t-mobile htc one m7 and using the correct 1877 code for t-mobile htc one m7 on my att htc one m7 the t-mobile value does not save in rf_nv_manager. I writed and saved then just reread without rebooting and the value reverted. we must be missing a step in the process.
[Sony Cross-Device General] regspy:
When i changed the NV using mztool, i didn't enable the USB into diag mode but only through the dialer. The changes on 1877 stick even after reboot and were working as by mistake i did an error and i wasn't getting a lock on GSM quickly.

Anyhow thanks to [MENTION=5353566]fffft[/MENTION] i will try to add the missing LTE bands NV 6828 on my verizon m8 and see if it works.
[Sony Cross-Device General] tjsooley:
How to you enable write enable?
[Sony Cross-Device General] tsaibru:
Mirrored in NV 6829 means input the same value?

When change NV 6828 is change of NV 1877 mandatory? Thanks.
[Sony Cross-Device General] regspy:
Damn big thanks to [MENTION=4300205]olokos[/MENTION] [MENTION=5733862]BlackSoulxxx[/MENTION] [MENTION=5353566]fffft[/MENTION]

Guys i unlocked europe LTE bands on my verizon M8.......im getting LTE signals after writing 131518 to NV 6828 and NV 6829

.....problem is that when LTE is enabled i can't make or recieve calls but i do get missed call sms notifications...

anyone can help?
[Sony Cross-Device General] tjsooley:
Thanks, It just resets too. I probable just need to play with it some more
[Sony Cross-Device General] olokos:
Good job!

You have LTE ONLY mode enabled thus no other radio is running, just LTE. Switch it to something like this and you will be fine. It's because VoLTE is not yet supported/used or just because LTE was built with faster DATA transfer, not voice.

It says LTE preffered on the screenshot.

If any of you guys would come up with something really helpful or useful in this topic then please mentioned me by writing [MENTION=4300205]olokos[/MENTION] and I'll add it to one of the first posts. :)

I haven't visited this thread in a while so I don't really know what's new or what's worth mentioning in this matter.

Any news about unlocking LTE on NON-LTE devices? If yes, then please write briefly how to check if LTE is locked and I'll add it here or I'll maybe just simply create a new thread with some other guide. :P

Dialed ##3424# in cdma mode to get into diag mode on phone.

Used the drivers from first post and in "device manager>Ports(COM&LPT)" installed the drivers on windows 8 pc. After drivers installation i got "HTC diagnostic interface(com6)"

Ran QPST configuration (ran as admin) and under ports added com 6 and phone was detected.

Ran RF_NV_Manager as administrator from bin/ folder

Used QXDM (ran as admin) to read/write NV values

Used mzTool and [MENTION=5353566]fffft[/MENTION] detailed guide to figure out the decimal/hex/binary coding and used the following converter Online Converter binary/hex/decimal to get all the correct stuff which are:

+1877: 2307813334317532032

+946: 0x0FE8

+2954: 537329664

+441:0x380

+6828: 131518

+6829: 131518

rebooted, and used Network app from google play to set the preferred network to LTE only as i dont have LTE(preferred)/Wcdma/GSM option Network App

Edit:

Changed from stock to ARHD 8.1 ROM (installed as international HTC one m8) and with network set to GSM/WCDMA/LTE AUTO, im able to get calls/sms working. Will test it out more later, but i recommend people with verizon HTC one m8 to unlock the europe bands for LTE which i mentioned above to get cracking and test themselves.
[Sony Cross-Device General] BobbySteel:
Wow nice work. Are data speeds good?
[Sony Cross-Device General] eldonly:
does any body test this on ZU for LTE-TDD?

could it suport this band?

thanks!
[Sony Cross-Device General] regspy:
Pretty huge bump in speed, although the signals ain't that strong at my residence i still manage 34.32Mbps download on LTE compared to 5.58Mbps on H

I'm located in Dubai, United Arab Emirates which has same LTE bands as European counterparts. So when you unlock LTE bands and test in europe the speed may vary.
[Sony Cross-Device General] BobbySteel:
That's great news. I'll have to give it a try over the weekend on the Voda UK lte network.

I wonder how well the CDMA side will work when back in the USA though. I guess the rom you're on won't work with CDMA, so I wonder if there's one best rom that handles all bands.
[Sony Cross-Device General] BlackSoulxxx:
Congrats! I knew that my works is right :p (Except for some big brand that keep us to buy locked band devices and make unlock band so hard that's near impossible*cough*Samsung*cough* )

[Sony Cross-Device General] sshark:
I am using Verizon VS980 LG G2 ON AT&T network. I can get WCDMA but not LTE where I leave.

I would like to use this mod but obviously seems more involved than a typical root procedure.

Has anyone tried this mod on LG G2? Does VS980 even have all bands available on hardware side?

(Xpost with Samsung thread...guess this is a broader thread for all Qualcomm devices)
[Sony Cross-Device General] gk1984:
I have a Sprint HTC One M7 and I keep finding mentions to change lines 6828 and 6829 for LTE in other devices. I'm missing these on the M7. Is this because they might be written differently on this device, the hardware isn't capable, or is there something else going on?
[Sony Cross-Device General] regspy:
install QXDM, you'll find the QXDM download link in ffft thread .....

and run as admin...then use the big dropdown infront of VIEW and choose "NV Browser"....

from NV browser window you'll be able to find all NVs including 6828 and 6829....just select the NV and first press READ to get the value...then insert your desired value and press WRITE
[Sony Cross-Device General] gk1984:
Thanks. Now I need to figure out how to manually tell Win 7 what drivers to use. I can get it to work properly on a Sense ROM, but I run a GPE ROM as daily driver - Win won't recognize it with diag drivers on this ROM and I can't tell it otherwise - only lets me install the same one I had before... Also, not sure how to enter diag mode on GPE, can on Sense though. Any advice? If not, I'll just mess with it on Sense since I know that works and figure out how to make changes permanent (if they work).
[Sony Cross-Device General] regspy:
mine is CDMA phone so i couldnt get the diag mode on anyother rom than the stock..and on that too i had to put the network to CDMA mode...and then dial the code to get diag mode on..

so if yours is a CDMA phone then i recommend make a titanium back...go back to stock do you unlocking of bands and then back to gpe...
[Sony Cross-Device General] sapplegater:
Anyone had any success with HTC M8 from T-Mobile running 4.4.3? Anytime I try to write the 1877 NV it just reverts back, tried using both RF_NV and QXDM but neither have been successful.
[Sony Cross-Device General] gk1984:
Alright, thanks I got it now but confused by the hex/decimal values and what not. I looked at, I believe, your post in another thread where you listed the values for the HTC One M8. earlier in this thread it was talking about calculating the decimal/hex values from binary and talking about reversed hex values. This thread doesn't mention anything about reversed hex values. So I don't know what I should do. I know I want LTE bands 25, 26, and 41. By using the binary method described and the converter/calculator you linked to, I got the values I needed (I think) but not sure if/how I reverse them before writing them. Also, I wanted to compare what the existing number (for example, line 6828) but I'm not sure if this is the hex number or not, nor if it's reversed.

Let me know if this is correct for bands 25, 26, and 41:

Binary: 00000000000000000000000011000000000000101

Decimal: 98309

Hex: 18005

Also, how do I verify what bands are already enabled here to also include them?
[Sony Cross-Device General] BobbySteel:
Just tried following your directions and it doesn't seem to be connecting to any network at all now. Will experiment more in the AM, but are you certain all the #s were the same as you used in yours?
[Sony Cross-Device General] regspy:
nop that binary is wrong

For LTE bands for just 25,26 and 41. Take the highest numbered band (band 41), then add 1. i.e. 41 + 1 = 42. So make a 42 digit binary number as follows (count from right to left starting as 0,1,2,3...). Digit 25,26,41 should be as 1s.

binary: 100000000000000110000000000000000000000000

decimal: 2199123918848

hex: 20006000000

---------- Post added at 12:53 AM ---------- Previous post was at 12:47 AM ----------

Hold on a sec, i just checked on a wiki. Vodafone UK has LTE on band 20, and not band 3/7 like my area. Can you confirm this? cause if its on band 20 then your LTE value should be different than mine. So after enabling band 20 as well (1,2,3,4,5,7,8,17,20) your decimal value for NV 6828 and NV 6829 should be 1180094
[Sony Cross-Device General] sapplegater:
Any other details of how you got it to work? Custom kernel? Rom?
[Sony Cross-Device General] ArtDC:
Anyone could help me out?

Hi there. I've got stuck for awhile trying to unlock a couple of LTE bands on my Xperia TL. I do have LTE's 2, 4, 5, and 17 unlocked and working originally. The NV6828 number for these is 65562 (I would expect it to be somewhat different based on the calculating rules here). I'd like to add the LTE 3 and 7 to the existing LTE bands. The binary I made following the guidance here and elsewhere is 100000000010111100, which is converted to decimal 131260. I wrote this into NV6828, or NV6829, and all I get is a mess. I don't get the bands I expect (eg. I get LTE18, and no 17, etc.), and as soon as I switch reception to LTE only phone reboots. I even tried the 131518 mentioned before, to no avail. I would be much obliged for pointing me into the right direction (provided such one does exist). A step-by-step guide would be greatly appreciated.
[Sony Cross-Device General] regspy:
Hmmmmm....Everything was stock, 4.4.2 with build number 1.54.401.10
[Sony Cross-Device General] sapplegater:
Hmmm strage, I've tried every rom and kernel I can think of to get it to work on my T-mobile variant and still get stuck at Writing the NV Value. Did you use QPST or QXDM? Did you do anything to achieve the ability to write to NV?
[Sony Cross-Device General] regspy:
Used QXDM to read write values, when you enable usb debeugging through the ADB shell command, did you also dial the dial code to put the phone into diag mode? When phone is in diag mode the screen will be black with three icons phone,pc and another.
[Sony Cross-Device General] sapplegater:
No I never got to a screen like that the code when I enter it just goes back to the dialer. The only code I've ever gotten to work on it is *#*#4636#*#* which is the info screen.
[Sony Cross-Device General] regspy:
Ok so that might be it, if it's stock Rom then first put your phone in CDMA only, and then dial ##3424#

Edit:

Oops yours is not a cdma phone, it's t-mobile. So that code might not work.
[Sony Cross-Device General] sapplegater:
It wont allow it to be put into CDMA mode it auto reverts back to GSM settings. :(

I am getting a diagnostics menu with *#*#3424#*#
[Sony Cross-Device General] regspy:
All this is new for me as well, but just reading a bit more. To get the phone in diag mode you either type the ADB shell command OR the dialer code.

In my case, I did both. So for you ONLY LTE values not writing the rest of NV writing is working?
[Sony Cross-Device General] BobbySteel:
Ah good catch, thanks. Giving this a try now. Also going to try and reflash a fresh stock ROM as well to see if that changes things.
[Sony Cross-Device General] sapplegater:
Yeah I've access ed it via adb with the code:

adb shell
su
echo 1 > /sys/devices/virtual/android_usb/android0/f_diag/on

I thought maybe cause it wasn't at that screen it wouldn't work, but so far the only thing I can get it for it to read the NV Values none of the values will write, the main thing is I just want to get LTE values written to open up LTE Band 2 since tmobile decided to launch lte in my area on the only band my phone doesn't have.
[Sony Cross-Device General] BlackSoulxxx:
The CDMA will not use-able (Just like my situation with Verizon phone, LTE got working on non official band but lost CDMA...)
[Sony Cross-Device General] sapplegater:
I'm on GSM so I don't need CDMA, its a tmobile phone.
[Sony Cross-Device General] regspy:
If USB debugging is on, then I guess the problem might be that the phone is not going in diag mode. Cuz once it is in diag mode it should write values.
[Sony Cross-Device General] sapplegater:
Yeah thats the only thing I can think off that could be causing it cause it obviously sees the com port and reads from the device just no write access, QPST says that device is in diag mode, so I dont know if its a false reading or not.
[Sony Cross-Device General] BobbySteel:
Hm, still nothing. 3G works fine but no LTE at all sadly. Will try a fresh ROM perhaps, but otherwise 7/20 don't seem to be functioning. I think VodaUK uses 7 only now so it should be working as far as I know.
[Sony Cross-Device General] regspy:
Can you confirm whether after reboot your values are sticking? Cuz with most people when they reboot the values revert back to default ones.
[Sony Cross-Device General] BobbySteel:
Yep they're definitely sticking. The NV editing worked fine for me.
[Sony Cross-Device General] regspy:
Ok then from network app just select LTE only. And see whether it connects.

Cuz if you on stock Verizon Rom, you can either connect to LTE/cdma or edge/3G. There's no option of getting both 3G and LTE together.

However, if you on ARHD Rom you can do all together cdma/gsm/wcdma/lte
[Sony Cross-Device General] BobbySteel:
I'm on cleanrom now which is stock. It has the wcdma /lte option as well as lte only. Neither get a connection in a known good lte area
[Sony Cross-Device General] regspy:
Damn! Wish it worked. I can't think of any other steps.

Edit:

EE in UK works on band 3 and 7, if you can borrow someone's SIM and test . That will at least confirm whether you've successfully unlocked the bands or not
[Sony Cross-Device General] sapplegater:
Is this similar to the screen you mentioned?
[Sony Cross-Device General] regspy:
Yes
[Sony Cross-Device General] sapplegater:
Okay yeah from what it looks like that screen is part of an app that is only included with the CDMA version of HTC devices :(
[Sony Cross-Device General] Slorks:
Wow amazing stuff really. Has anyone tested this on the Motorola Moto X XT1095 pure edition? According to the Moto site its supporting LTE 2,4,17 but on Wiki and many bother sites it says 3 is supported on it but software restricted.

Anyone?
[Sony Cross-Device General] oksagi:
Can you show which interface and port you used? i have 2 interfaces.

Interfaced diagnostic COM4

interface diagnostic 9k COM3

The only one can connect trough QXDM it with 9K.
[Sony Cross-Device General] LLStarks:
I have a Galaxy S3 i535 (Verizon) running CM11

Verizon explicitly disabled HSPA bands for AT&T and T-Mobile at the modem blob level

Will I be able to enable them?

What about additional LTE bands?
[Sony Cross-Device General] BobbySteel:
Can't seem to find an EE SIM right now. I've tried a bunch of other ROMs today and still no luck unfortunately. I also tried just updating to the latest firmware as well, which hasn't done anything either. On the plus side I'm getting much faster speeds since HSPAP seems to be workign where it wasn't previously (only HSPA on Vodafone before). So that's a win.
[Sony Cross-Device General] regspy:
maybe someone with the knowledge of editing NV can enlighten us, 'cause i thought if you update the firmware the newer baseband will overwrite whatever NV edits were made earlier.

---------- Post added at 02:35 PM ---------- Previous post was at 02:33 PM ----------

I don't get two options, i just have one which is without the 9K
[Sony Cross-Device General] BobbySteel:
Yep I had to redo the LTE NV edits. The rest were still there. Still no luck though.

---------- Post added at 03:13 PM ---------- Previous post was at 03:12 PM ----------

BTW did you write down what the old values were everywhere before you changed them? In my eagerness I forgot to do this before I made all the edits!
[Sony Cross-Device General] regspy:
wrote down not all but few of them, but once you do RUU everything will back to default.
[Sony Cross-Device General] oksagi:
Are guys using CDMA device?

I'm on M7 developer Edition.

I have 2 interfaces on the device manager.

Only K9 connection to the device with QPST and QXDM.

There are few NV items that i can edit and the remained with the changes: 441, 2954 and 946.

The others NOT : 1877, 6828 , 6829.

I think that i know why.

I need to force my device into CDMA mode, but there is no luck on trying.

When choosing CDMA only its changed automatically back to WCDMA(the value before changing).

How to force M7 developer edition that have multi band(WCDMA, CDAM Evo , etc') switch to CDMA network without a simcard.

I see that there is dependence on some NV items to change other one, but with NV items controls that network the will be used on the device?

Is this hardware capped? or it's only some HEX on the NV items that need to be adjusted for that?

Any help will be appreciated.

I have Verizon LG G2 running on ATT network without any issues with WCDMA network.

I am interested in unlocking LTE bands...

Anyone has crossed ship from CDMA to GSM for CDMA phone?
[Sony Cross-Device General] LLStarks:
I can't get the NV settings to stick through a reboot.

Is my modem partition simply enforcing whatever was hardcoded in?
[Sony Cross-Device General] BlackSoulxxx:
Verizon is crap for capped the GSM capable on their device. Luckily I was able to unlock gsm for my cdma phone. The only drawback is CDMA is stop working (cant switch to CDMA) but GSM it's fully functional with WCDMA/LTE.

And for anybody with nv value reset after reboot, try to update baseband/modem/radio software to latest and try to use AOSP-base kernel and rom......
[Sony Cross-Device General] oksagi:
Do you think that HTC / Samsung are blocking the changes on their based roms?

Will try on CM11 today and report back.
[Sony Cross-Device General] w1n73rf3ll:
yes is hardware!.. i have one from sprint but before i have one from AT&T and the hardware its different even the HTC ONE from Sprint Have 2 more Antennas!.. the HTC ONE from AT&T doesnt suport CDMA for that!.. i have one from Sprint i want yo enable the other GSM and 3G bands any advice help? im stuck too :(
[Sony Cross-Device General] oksagi:
I know that.

This is not what i'm pointing in.

The Developer Edition, does have WCDMA/GSM/LTE/CDMA support.

It doesnt have all CDMA options like chipset/modem from Verizon or sprint does.

I'm asking the question because in QXDM the category of 1877 NV is CDMA.

So as i figured for now, we cannot change those values on GSM device until we force it to CDMA network.

Actually when forcing my M7 to diagnostic mode, i have 2 interfaces:

diagnostic interface it's belongs GSM/CDMA

diagnostic Interface K9 it's belongs to LTE.

So far as i see, on HTC device that are branded as GSM, cannot change the CDMA values.

I can say more, the LTE NV 06828 it dependence on NV 1877.

Can somebody confirm that on M7/M8 that non CDMA brand device successfully changed the 1877 value and the changes are persist?

How about LG devices, can someone confirm on LG G2 changed values 1877 succesfully?
[Sony Cross-Device General] ftorres:
Mine is E8, support GSM/CDMA/LTE. But I could only use 3G as I unlock gsm from CDMA carrier. All the nv values I changed stick, but still no LTE. Sigh

Edit: value for LTE stick using QXDM, 1877 stick using QPST. Didn't change other value as I only wanted to enable additional LTE band
[Sony Cross-Device General] oksagi:
Your E8 is from CDMA carrier? or it's international version?
[Sony Cross-Device General] ftorres:
China telecom CDMA version. Think LTE is blocked by carrier as the hardware support TD/FDD LTE
[Sony Cross-Device General] oksagi:
OK, this make sense.

Your device is CDMA device.

Mine is GSM, so as i mentioned before, the need to force it as CDMA to open connection by diagnostic port as CDMA

i think that 1877 value can be change as CDMA device and not GSM

[Sony Cross-Device General] regspy:
not sure whether the hardware supports it, but to open LTE band 14 along with other you should enter the following:

NV6829: 147902

Hey Regspy thanks for the input, I'll definitely try that. But I'm already very happy as you can imagine, lte everywhere!
[Sony Cross-Device General] BobbySteel:
Are you able to connect on another lte band? Which one? I can't seem to make 20 work here.
[Sony Cross-Device General] oksagi:
When you unlocked the LTE bands, was you on Verizon ROM? or INT?

Why i'm asking, the Dialed ##3424# code can be used only on Verizon ROM. correct me if i'm wrong.

So what i think to do, is install Viper Rom as Verizon carrier settings, and see if i can managed the connection as you did.

Tell me please, when you entered the code, what happened on the screen? and was you offline or online? and was there in sim card in the slot?
