hi,

does this work with sprint m8? i'm using the phone in the philippines, and the frequency bands we use here are

GSM Frequency Band - 850MHz/900 MHz/1800 MHz

3G Frequency Band- WCDMA (UMTS) - 850Mhz/2100 MHz

UMTS/3G 1900(uplink)/2100(downlink) (Dual Band)

4G (live LTE, WiMAX, HSPA+, test, license) - LTE HSPA+ WiMAX 850/1800/2100Mhz

which instructions should i follow, i believe i read that there is one instruction with the HTC driver and the other is LG.

thanks
[Sony Cross-Device General] BobbySteel:
I can confirm now that by only changing my build.prop and the Lte NV value, I've had my verizon m8 work with att lte in the US (on a Vodafone UK sim), euro lte on band 20 in France, and by changing the build.prop back to stock, still retaining verizon lte capabilities.
[Sony Cross-Device General] atulnaidu:
Hi,

Will this work for the Samsung Mega? I believe it also has a Qualcomm chipset.

Thanks
[Sony Cross-Device General] rusalex2k8:
hi, I have a some problem maybe someone can confirm or give me some advise how to fix it, I have z1 compact , I unlocked all possible umts and lte bands on my phone but I have strange problem, it works fine day or two than when device loses signal, it can't to find network at all. factory or customization reset from service menu helps and it works fine again ( but all unlocked bands disappear) I tried to unlocked not all bans just a few extra , the same problem , any suggestions?
[Sony Cross-Device General] botwa2000:
Also interested to know what changes you made to build.prop.

Cheers!

hi regspy and olokos,

i have a sprint m8, running bad boyz rom. i followed olokos' and regspy's instructions but not entirely because i have a different phone and things happened differently for me.

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

- i didn't have to go to cdma mode anymore do get into diag mode, even in gsm mode, the diag mode appeared, clicked on DM ON and clicked on SELECT.

plugged in my phone, computer detected it and automatically installed the HTC DIAG driver, i got HTC Diagnostic Interface (Com 6) in device manager. i'm running windows 8.1 64bit by the way.

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

- i did this

"Ran RF_NV_Manager as administrator from bin/ folder"

- also did this

did steps 20 to 35 of olokos' instructions in the first post.

after reboot, i could not change network settings, it just stays on CDMA only, saying i dont have a sim card.

is this necessary for me?

"adb shell

su

setprop persist.usb.eng 1"

i did not do this.

tried installing the modified drivers, but my system wont take it, saying make sure i have a 64-bit driver, also tried it under windows 7, same thing. please tell me what i did wrong.

thanks
[Sony Cross-Device General] confli©t:
hi,

i am also getting this, no sim card after unlocking other gsm bands, haven't touched LTE yet

thanks
[Sony Cross-Device General] BobbySteel:
Why don't you all start with a stock ROM before doing all of this? I started with a stock one to eliminate other variables. In the case here I suspect the problem is using a GSM rom which is not necessary if you match the build.prop.

I'll post more clear directions later but the essential line to change is about lteoncdma or similar. The phone needs to know lte should fall back to wcdma/gsm versus CDMA.

---------- Post added at 09:20 AM ---------- Previous post was at 09:16 AM ----------

Also at least on the verizon model, I recommend not changing any NV values except 6828 and 6829. The others will render your CDMA functionality useless and I couldn't recover it even by changing these values back.
[Sony Cross-Device General] confli©t:
hi bobby, does this apply to me as well, i'm using sprint. the only thing i changed is 1877, wanted to fix UMTS bands first before tinkering with LTE. when i changed the value back to its original number, i was able to get signal back.

thanks
[Sony Cross-Device General] BobbySteel:
I think you should be fine. Fixing umts was not a priority for me versus lte. I just think the info upthread is a bit confusing and the NV values not good unless you want to eventually kill all CDMA like I did
[Sony Cross-Device General] confli©t:
tried with stock sprint rom, same thing, after unlocking, no sim card detected
[Sony Cross-Device General] BobbySteel:
Well if you're changing 1877 I think you have to change all the other bands in the other NV fields too. I can't explain what's happening to you, but it might be worthwhile to double check all the calculations for the other numbers using the mztool and only adding the bands that are necessary. I got some weird errors previously when experimenting with 1877 and the other non-lte NV values.
[Sony Cross-Device General] confli©t:
hi bobby,

1877 is for GSM/CDMA, 6828 and 6829 are for LTE, right?

what are 946, 2954 , 441 for? why do i need to change them?

thanks
[Sony Cross-Device General] BobbySteel:
Those others are for other various non-lte RF bands. Approach with caution. The mztool shows how they're calculated. It seems 1877 acts sort of as a checksum for the others which I find confusing and don't understand well enough myself.
[Sony Cross-Device General] confli©t:
i read fffft's instructions on how to compute for the other NV's, might try that one. and i missed a step, didn't use QXDM

will report back
[Sony Cross-Device General] confli©t:
when you say, write "0" to enable write in qxdm, do you simply just press the write button?
[Sony Cross-Device General] confli©t:
oh, still the same. pressing ##3424# in the dialer, brings me to DM Command Service, then i click on DM On, is this even the diags mode that i need to be in? do i really need the HTC Diag Driver? because, with just HTC driver from HTC Sync, my computer detects the phone, it even says HTC Diagnostic Interface (COM4) in device manager.

thanks
[Sony Cross-Device General] confli©t:
here is where i'm stuck, it seems no matter which method i follow, when i change the NV values, be it just for LTE, or just GSM/WCDMA, or both, once i restart, i have no signal and if i try to change network type, it says i dont have a sim card.

also, when using qpst's serviceprog.exe program, when i press write to phone, comes up with an error, first i get a window, says "ban" with an exclamation point, then another window saying my imei is read only, and no, i didn't try to change my imei.

please help, anybody
[Sony Cross-Device General] regspy:
i dont own a verizon m8 anymore, however i had a sprint M8 in the past and i had to unlock the GSM sim functionality on it first as it isn't unlocked right out of the box like verizon phones.

So what i recommed to you is unlock the sim for GSM sprint m8 sim unlock
[Sony Cross-Device General] confli©t:
hi regspy,

i already have, i'm already using my m8 here in the philippines. but signal coverage is not good and lte is not working because not all the GSM bands available here are supported by the phone. LTE band available here is also not currently supported by my m8.

thanks
[Sony Cross-Device General] regspy:
ok so after activating the bands did you try installing the network app from playstore? which will allow you to choose network like EDGE/WCDMA/LTE AUTO ?
[Sony Cross-Device General] confli©t:
yes, it wont let me change the settings. if i leave it on edge/wcdma/lte auto before activating the bands, it's on theat setting but i dont have a sginal. if i go to mobile network settings under settings, and try to change the network mode, it keeps saying i dont have a sim card installed and that the phone would revert back to CDMA
[Sony Cross-Device General] BobbySteel:
Weird. I can't give you any advice on that. Did it ever work on gsm before you changed the settings?
[Sony Cross-Device General] confli©t:
yes, it worked. and still working, everytime i activate bands and doesn't work, i always use qpst to restore from my backup
[Sony Cross-Device General] regspy:
Activating LTE bands and GSM bands are two different things, i would recommend you stick to default values for the GSM bands as atleast you will get a signal....and once you've got the gsm working then ONLY change LTE bands..... and make your NV values are sticking after reboot
[Sony Cross-Device General] confli©t:
my stock value for 6828 and 6829 is 50331648. now, i dont know how to get this if i reverse calculate. pressing ##DATA#, we get to see EPST right? and from there, we can see LTE, there's BANDS 25, 26, 41 listed, so that's available LTE bands right?

binary is 100000000000000110000000000000000000000000, and using binary to hexadecimal you provided, i get 2199123918848 for decimal and 20006000000 for hexadecimal. so where did 50331648 come from? am i missing something here?

i used VNDNGUYEN's qualcomm NV Calculator app and hoped to get 50331648, selected LTE bands 25,26,41, and i get 1,099,561,959,424 for the QXDM notation which is default, and under standat notation, it's 2,199,123918,848. they are still not 50331648.

ok, something different happened this time, i only changed LTE settings, didn't touch GSM/WCDMA anymore. ran QPST and once phone is connected, opened QXDM, didn't anything except 6828 and 6829

now, i just tried this, used VNDNGUYEN's app, since my stock LTE bands are 25,26,41, i selected them and added bands 1 and 3. i get 1099561959429, this is the QXDM notation. edited 6828 and 6829 only with 1099561959429, rebooted and i still have signal. for the first time, it's not rejecting my sim, if i check if the values stick, they did, but if i press ##DATA# and check under LTE, still only bands 25,26 and 41 are there :(
[Sony Cross-Device General] regspy:
Also, just checking in the forums.....Enable/Disable Bands on sprint m8

1. Go to dialer and enter ##3282#

2. Enter your MSL password

3. Go to Advanced then LTE and choose enable

4. On the main EPST menu choose LTE

Can you see the enabled bands ??

EDIT: NVM i guess you already did this
[Sony Cross-Device General] confli©t:
hi regspy, i can, but on EPST>LTE, only 25,26,41 are there, i can enable and disable them. i still dont see bands 1 and 3.

by the way, how did you get 131518 for your 6828 and 6829, i'll try to replicate your method and see if it'll work

thanks
[Sony Cross-Device General] regspy:
can you enter 131518 value for 6828 and 6829? tell me what happens

I actually calculated the 131518 on my own and enabled lot of european and asian LTE bands......

To enable your band 1 and 3 along with the default you should enter 2199123918858 value for 6828 and 6829

To disable default 25,26,41 and enable just your band 1 and 3 you should enter 10 value for 6828 and 6829

Just check wikipedia it seems in phillipines LTE is offered on several bands so you can try the following value 6597069766826 for 6828 and 6829 (this enables LTE band 42,41,7,5,3,1)

Also, answering your question regarding 50331648 default value. It actually activates band 25,26 and NOT 41. So by default 41 is disabled.
[Sony Cross-Device General] confli©t:
ok, i'll try that later regspy and let you know. bobbysteel and regspy, thanks to both of you for helping, will report back later.
[Sony Cross-Device General] sipe1:
One question, can I unlock LTE on C6002 Xperia Z ? Anyone tried it?
[Sony Cross-Device General] confli©t:
hi [MENTION=4220801]regspy[/MENTION] and [MENTION=2604616]BobbySteel[/MENTION],

you are correct regspy, 50331648 is just for bands 25 and 26. i rechecked with the qualcomm nv calculator app, and chose just 25 and 26, i got 50331648. went back to EPST>LTE and check, 3 bands are listed, 25,26 and 41 but 41 is disabled. i tried 2199123918858, 131518, and 10 on 6828 and 6829, but when i check EPST>LTE, only bands 25,26 and 41 are listed. even if i disbable 25,26 and 41 and just activate 1 and 3, when i check EPST>LTE, 25, 26 and 41 are listed but says disabled, bands 1 and 3 are still not there. if i'm successful, should bands 1 and 3 be listed under EPST>LTE?

did a little experimentation...on default, where 25 and 26 are enabled, if i use the NETWORK app from play store, i could select LTE only, although ofcouse i wont get any signal. but if i disable 25,26 and 41 and activate 1 and 3 only, i could not even choose LTE only under the NETWORK app. is it because, the phone knows, 25, 26 ad 41 are disabled and bands 1 and 3 are still not activated?

another thing, even just bands 1 and 3 activated, NV value is 10 right? but if i go to EPST>LTE and enable 25, 26, 41, and check the NV value under QXDM, it changes automatically.

---------- Post added at 11:58 AM ---------- Previous post was at 11:56 AM ----------

i think, even if the NV value i input is correct and it sticks, the phone is still not activating bands 1 and 3, is there anything else i need to do?

and is there any other way to check which bands are available? or is it just under EPST>LTE?
[Sony Cross-Device General] botwa2000:
I've got the same issue on my Galaxy S5. NV edits on 6828 & 6829 stick after the reboot but the new LTE bands don't appear in the phone's service menu nor they are operational.

So it's either a hardware limitation or further software configuration is needed.
[Sony Cross-Device General] regspy:
require more researching, i guess its either ROM based restriction (if you change the ROM to lets say ARHD 8.1 install as GSM, can you get LTE activated? is EPST still accessible on ARHD ROM?)

OR

might have to look for another NV value where 25,26,41 are hard coded

EDIT:

I think its the PRL which is blocking the use of LTE. Now if someone with a bit more knowledge on it, i guess we can try using a PRL in 55XX or 56XX and this will enable worldphone LTE
[Sony Cross-Device General] botwa2000:
To the ROM :

My S5 is actually SM-G906K model so there isn't much in a way of customisation it there yet. However I doubt this is the issue as I am rooted and had no problems getting the device into the permissive diag mode and editing the nv values.

I though PRL was mostly used by CDMA devices? Anyway do you know how I access it?
[Sony Cross-Device General] confli©t:
oh this is so frustrating...

went back to activating GSM/WCDMA, left LTE untouched this time. it seems that settings on 441 dont stick.
[Sony Cross-Device General] regspy:
This might be a longshot, but maybe just maybe its not the PRL... can you try editing the build.prop with the following:

Change this

telephony.lteOnCdmaDevice=1

to

telephony.lteOnCdmaDevice=0

and add

telephony.lteOnGsmDevice=1

ro.telephony.default_network=9

See whether this change will allow your device to finally work on LTE.

Do this with extreme caution as it might brick your device.

Also in EPST disable all three sprint bands 25,26 and 41.

HTC M8 Sprint GSM / WCDMA additional bands unlock

good news first :)

i've already unlocked additional bands for GSM/WCDMA, although, might have already done that few days ago, without me knowing.

the method that worked for me was from this post

http://xdaforums.com/showpost.php?p=52585497&postcount=34

almost the same as [MENTION=5353566]fffft[/MENTION] instructions, except for the part where you need to choose automatic for roam preferences on the system tab and on the UMTS System tab, choose ANY for pref service domain. don't know if those settings mattered.

when i was doing things manually in QXDM, nv 964 and 2954 would change settings and stick, nv 441 would always revert back to ANY. and whenever i manually edit 1877, upon reboot, i dont have a signal and phone keeps saying i dont have a SIM card installed.

but when i used QPST's service programming, i checked the bands that i need under UMTS, and clicked write to phone, but i always get an error message saying NV_IMEI is read only (now, i know it doesn't matter, only imei is read only, the rest, we can overwrite), but what bugged me the most was, eventhough the bands i need stays checked in service programmin, whenever i check my nv values in QXDM, they dont change, so i thought, it wasn't working.

so last night, before going home, i used QPST's service programming again, settings stuck in UMTS tab but nv are the same in QXDM, went home and didn't revert back to original settings since it's sim card is working anyways. when i got home, the part of our house, where i always only get a GPRS connection, never an H (HSDPA), now i get an HSDPA! so that means, i opened up some bands right? but it's really weird that the nv values in 1877 didn't change. anyway i could check which bands are available? but i am happy with my GSM/WCDMA coverate now :)

---------- Post added at 11:56 AM ---------- Previous post was at 11:53 AM ----------

hi regspy, did this. changed 1 to 0 for telephony.lteOnCdmaDevice. added telephony.lteOnGsmDevice=1

ro.telephony.default_network=9

saw that there's ro.telephony.default_network=8, deleted it.

edited 6828 and 6829 again in QXDM, same thing.

if i disable all bands (25,26 and 41) in EPST, EPST>Advanced>LTE gets disbaled

---------- Post added at 11:59 AM ---------- Previous post was at 11:56 AM ----------

@BobbySteel is this also what you did with your build.prop?

when you flash a new rom, whatever you did with the build.prop gets undone right?

---------- Post added at 12:00 PM ---------- Previous post was at 11:59 AM ----------

@BobbySteel
[Sony Cross-Device General] regspy:
I might be wrong, but may QPST might be editing PRL and not actual NV values. Does QPST allow to edit LTE bands? Also try adding the NV values without the 0 on the right so to enable 7 bands type one, seven times 1111111
[Sony Cross-Device General] BobbySteel:
Yep this is what I did in my build prop. A new ROM flash overwrites it back to stock

Sadly on the Verizon m8 I can't seem to pull up epst to check LTE settings though. How did you do it with your sprint m8?
[Sony Cross-Device General] confli©t:
hi regspy, what do you mean? write "1111111" in nv 6828 and nv 6829?

there's not setting in QPST that would allow you to edit nv 6828 and nv 6829. i saw an LTE NAS tab in service programming, but i didn't touch it

---------- Post added at 12:32 PM ---------- Previous post was at 12:31 PM ----------

i pressed ##DATA#, ##3282#. but sometimes, when the phone has just booted up, it wont come up, you might need to wait a minute or 2 and try again

---------- Post added at 12:33 PM ---------- Previous post was at 12:32 PM ----------

tyep 1111111 in QXDM?

---------- Post added at 12:58 PM ---------- Previous post was at 12:33 PM ----------

@BobbySteel and [MENTION=4220801]regspy[/MENTION]

"telephony.lteOnCdmaDevice=1

to

telephony.lteOnCdmaDevice=0

and add

telephony.lteOnGsmDevice=1

ro.telephony.default_network=9"

changing 1 to 0 in telephony.lteOnCdmaDevice, obviously turns lte off when in cdma mode.

and adding telephony.lteOnGsmDevice=1, means enabling lte for GSM

what does ro.telephony.default_network=9 do?

i also saw ro.telephony.default_network=8 on default

what does 8 and 9 mean here?

thanks
[Sony Cross-Device General] regspy:
ro.telephony.default_network=9 explained here

I'm getting sprint M8 in couple of days time, so will try my luck with enabling LTE on it....and will revert back with my findings. For now, i'm just reading what CDMA tool does. If PRL is just about preferred roaming list then maybe we can enable global LTE bands in there.

Requires more researching, once the NV values have been edited. Then its all about getting them to show in EPST.

Will try different radio, kernel etc as well just to see if the limitation isn't in the sprint one
[Sony Cross-Device General] confli©t:
that's great :good: really thankful :)

what did you mean with the seven 1's? where should i put it? just want to try while waiting

[Sony Cross-Device General] liu2002:
I am using xperia z, how to open the diag mode with cm11.
[Sony Cross-Device General] regspy:
Sorry, i meant creating the decimal value out of the binary code without zero on the extreme right side (so for example if you had to activate 7 bands of LTE, rather than 11111110 make it 1111111 and get the decimal value which in case of this example would be 127)
[Sony Cross-Device General] confli©t:
ok, i'll try that and let you know

---------- Post added at 10:42 PM ---------- Previous post was at 10:27 PM ----------

nope, sorry, it still wont show up in EPST>LTE

noticed something, i think that's how VNDNGUYEN's app computes for the NV of LTE bands, without the first 0 on the very right.
[Sony Cross-Device General] sshark:
For editing 6828 AND 6829, use QXDM, QPST won't show certain NV items.

I have been unsuccessful in editing NV on LG G2 Verizon but I also didn't have BUILD.PROP tweaks that BobbySteel mentioned.

I am going to try tweaking 6828 and 6829 again now after adding new build.prop values.

----

It might be a good idea to compare build.prop for a comparable GSM device against CDMA one...for example comparing LG G2 GSM vs LG G2 CDMA etc. Etc.
[Sony Cross-Device General] afextwin:
Has anyone tried adding Verizon's LTE band to a USCC S3? If so, were you able to get a Verizon or MVNO of VZWs SIM to activate or read in the device?
[Sony Cross-Device General] equake:
If you ever get the tweaks to work and the LTE bands unlocked let us know what ROM/Kernel combo you are using and the steps needed. I am willing to replicate on my VZW G2 on XDABBEB 2.2.x.

Thanks
[Sony Cross-Device General] sshark:
I have Cloudy G3 with default kernel and some built.prop changes that I mentioned earlier.

I can edit WCDMA related NV items but after editing I lose GSM signal. While I can make changes to LTE NV items, those changes don't stick after reboot.

I am going to repeat the process tonight and will let you know outcome.

Still no love for a Docomo Aquos ZETA SH-04F? I've tried to follow the steps but I still cant seem to get it going lol

Since this phone isn't your average android phone, i feel like there are some other "special" steps to takes

Any help would be greatly appreciated! I'm currently on AT&T and unlocking the LTE function would be great! :D

Thank you!
[Sony Cross-Device General] equake:
It seems the radio config is forced to take the RUIM/SIM rather than the NV so it doesn't work after reboot. Since I'm not at all familiar in how these work I can't speculate on how to bypass perhaps on boot the init.d can run batch to reset it. There is a setting in the hidden menus to select this under the Moblile Networks submenu. Note the spelling mistake lol (intentional)...

my 2 cents.
[Sony Cross-Device General] regspy:
ok just got the sprint m8, seems like somewhere in this CDMA phone some code is restricting it to access any other LTE band other than 25,26.

If someone has any knowledge of where is this restriction placed let us know. Cause in NV 6828 and 6829 other LTE bands have been added but phone doesn't seem to work on any other band at all..

either its a hardware restriction or some software.
[Sony Cross-Device General] BobbySteel:
So my key insights so far:

On a freshly stock Verizon M8, I was able to get AT&T US LTE using a Vodafone SIM and SFR (France) LTE using the same Vodafone UK SIM. However I cannot get Vodafone UK LTE despite it using the same bands as SFR. My only guess is that SFR is primarily using Band 20 and Voda UK is on band 7 mainly, and this radio doesn't handle band 7? Very odd to be honest.

For build.prop, I basically took a GSM M8's build prop and used that, while backing up the Verizon build.prop to use on my return to the US.
[Sony Cross-Device General] sshark:
I think activation of LTE while outside US is actually allowed by Verizon.

Real test will be when you land here and use ATT Sim to see whether ATT LTE is working or not.
