I think anyone who wants to change the information bands should give their original information.

This way we can compare them and change with original codes/values.

put this way:

NV #441 : XXXXX

NV #946: XXXXX

NV #2954: XXXXX

NV #1877: XXXXX

LTE #06828: XXXXX

LTE #06829: XXXXX

PHONE: MODEL NAME - MODEL NUMBER - REGION

LTE BANDS: X,X,X,X

UMTS, CDMA, WCDMA(OTHERS): XXXXX

I know that will be hard to fill all this things, but will help us to find out if it works or not.

Maybe someone in others regions can help you with their codes and vice versa.

Just remember to only use does informations in the same phone to make sure will it work. For example - HTC ONE M8 from US to HTC ONE M8 from Europe.

In my case my original informations are this:

NV #441 : 0

NV #946: 0

NV #2954: 0

NV #1877: 562950069289344

LTE #06828: 65563

LTE #06829: 0

PHONE: XPERIA ZL LTE - 6506 - US UNLOCKED

LTE BANDS: 1,2,4,5,17 (700 / 850 / 1700 / 1900 / 2100)

UMTS, CDMA, WCDMA(OTHERS): UMTS - 1,2,4,5,8 (850 / 900 / 1700 / 1900 / 2100)

I need the information from the Europe version.

You can find the especifications in websites like GSMARENA.

This will make our lifes easy.

Hope everyone understand what I'm trying to explain.

Cheers

Has anybody got unlock nexus 5 LTE bands? D820 to D821? Is it possible?
[Sony Cross-Device General] tjsooley:
Thanks, Now the only thing for me to figure out is whenever I write the new nv data to enable bands (this happens with all band related nv's) the data does not stick but its not that simple if you re-read the nv data after hitting write it reverts. this also happens with the zero trick.
[Sony Cross-Device General] galliard:
band info tool

Moderator Edit: Do not quote the whole OP

What is the name of tool which is showing band info in snap?
[Sony Cross-Device General] tjsooley:
I think it is the kitkat anti hack. I just tried it started from step 1 of the op and same thing happens.

Thanks
[Sony Cross-Device General] regspy:
Was on verizon stock ROM.

But recently i updated the firmware which overwrote the NVs and this time i was on a custom ROM (viperonem8 2.5) and i was able to successfully open the bands by just enabling the USB diag mode through ADB command and not the dialer code (dialer code only works on stock ROM)
[Sony Cross-Device General] coglyostro:
My bad, but if see two posts above the one you answer me I did a better explanation of what I want.

Basically this number that I give (65563) it is a decimal number that I get from QXMD in the line #06828, which correspond to a LTE part on QXDM.

The equivalent fo this number should be 1/2/4/5/17 LTE bands, since it is the original bands my phone works.

This NV 6828 : AA 01 10 you gave, where I'm supose to use, because I don't see any number similar to this in QXDM. Can you make this in decimal?

Thanks for your help.

Cheers
[Sony Cross-Device General] BobbySteel:
has anyone figured out a way to show active bands on the HTC phones? I can't seem to pull up a service menu. Trying to figure out why I can't connect on LTE band 20. NV #s are correct, but radio won't pick up any connection.
[Sony Cross-Device General] coglyostro:
Actually I didn't made any miss calculation. This decimal number - 65563 - was the QXDM software that read for me.

I just read the value through the software and this number came up, so I suppose it was related with the original bands that my phone has.

Something is missing in those information and this is why it's no working for most of us.

I put the value you gave to me - the decimal one 1049002 - and the band that I want, not even show up in the service menu, and obviously didn't work.

Just for curiosity I put the number backwards, to make sure I was doing everything possible, and dosen't work either.

Maybe the calculation for my phone is different, I don't know.

Like I sad before, if someone with the europe version of this phone can give their original value, maybe it will work otherwise it is a dead end.

I wish I could get this thing working, but it seems will be harder than just change some numbers here and there.

Anyway, thank you for your help again, I will keep trying.

Cheers
[Sony Cross-Device General] coglyostro:
I think I wrote in wrong way.

What I meant is that I made no calculation at all and that this was the value that I got through the QXDM version 3.12.714.

You get me wrong here and I'm sorry because was not my intention to do so.

I never said you were wrong, in fact I'm learning with you

I do not know anything about this thing.

Again thank you for your help.

I'm really good to talk in english but not much in writing. :P

Cheers
[Sony Cross-Device General] BobbySteel:
On my m8 now in Malta and no LTE here either. I'm doubtful that the directions regspy posted are correct entirely, as there should be lte networks visible here now and I'm not getting anything at all. Regspy, can you reconfirm your settings? I cannot reproduce your success.
[Sony Cross-Device General] marquimsp:
Kinda OT but do you guys know a phone that works with 4G both in Europe/Brazil and in the USA? Bands 7 and 4 maybe?

Thanks!
[Sony Cross-Device General] ShiAili:
Dear all, I believe I can shed some light on the "Band 0" / bit 0 issue. It seems on my device using QXDM 03.12.714 that NV 6828/6829 bit 0 = band 1. I'll explain more bellow.

I have had partial success - been fiddling with my Xperia Z2 D6503, running rooted stock 4.4.2 Build 17.1.2.A.0314. I purchased it in Taiwan, unlocked, as distributed through Sennao International (Chunghwa Telecom). Default LTE bands are 1/2/3/4/5/7/8/13/17/20 (FD-LTE US 700 [13/17]/800/850/900/1700/1800/1900/2100/2600). I've been trying to get B28 (APAC 700), as I am using LTE on FarEasTone - who operates LTE on B3 and B28 (700 APAC/1800 DCS) to take advantage of their more widely deployed b28.

While I have gotten it to display in the service config menu, I haven't been able to verify connection. When I tried enabling only B28 to the exclusion of all others, I got no LTE coverage, and I was unable to set "LTE Only" mode from *#*#4636#*#*. It works fine using default bands + B28. I know that LTE B28 has been deployed in my area, but I have no way of distinguishing it from B3, and so can't tell if it's taking.

I also tried using the same band setup as the Taiwan-only Z2a - which supports B28 - as it has been widely reported that these use the same SoC (though I cannot verify). No luck, but I only did one trial

I used the initial steps outlined in the first post, but used QXDM for editing NVs. Here is my log of the various trials and permutations attempted, in chronological order.

NV 6828 for QXDM LTE
Default
594143
0b100100010000110111110
WRONG. Correct one is:
0b10010001000011011111

New? Derived from Z2a
700 / 850 / 900 / 1800 / 1900 / 2100 / 2600
Bit 28 700 APT
Bit 5 850
Bit 8 900
Bit 3 1800
Bit 2 1900
Bit 1 2100
Bit 7 2600
12357828
0b10000000000000000000110101110
Dec: 268435886

Possible mirrored value located at: NV 6829. Often misposted 6929

Results: Changed both NV 6828 and NV 6829. Config menu doesn't load. 6829 showed inactive - after no results with NV 6828, mirrored settings to NV 6829
Reverted.
Attempting to implement 0 bands to see if LTE can be disabled (and therefore manipulated) through qxdm

Accidently Set for dec 3 (0b11), hoping to enable band 1 - but accidentally enabled bands 1 and 2 - proving that bit 0 is actually band 1 - contrary to outside data

Will now attempt to reset for only B28 using bit 0 = b1.
0b1000000000000000000000000000
134217728

Result: No LTE.

Now attempting with bit 1 = b1 for B28
0b10000000000000000000000000000
dec: 268435456
Also no band results.

Now attempting mirroring both NV 6828 and NV 6829 using bit 0 = b1
134217728...
Also used "Write 0" trick first.
B28 shows up in configuration menu, but does not connect and does not detect other carrier's 4G networks.

Ran antenna diversity tests. All failed with LTE.

Will now attempt mirroring default + B28. Will use Bit 0 = B1, mirroring and "Write 0"
0b1000000010010001000011011111
134811871

Shows B28 in addition to standard. Connection unclear. More experiments later.

Next experiment? Use Z2a bands with bit 0 = b1
0b1000000000000000000011010111
134217943
Not yet attempted.
[Sony Cross-Device General] BlackSoulxxx:
Try to use 1111111111111111111111......(44 number, all 1) bit to see......

Z2a is capable of CDMA (via special unlock band method) so I not sure you can use that value.....

Or just find the band 28 that have rf calibration value in QXDM??
[Sony Cross-Device General] ShiAili:
Tried using B28 only with no luck. Haven't tried all 1's yet, as my initial testing suggests that having B29 enabled breaks the configuration menu. Will attempt during next experiments.
[Sony Cross-Device General] skarface1988:
After the *#*#8778#*#* it shows nothing, is that suppose to happen?

And when I use the terminal emu. And type adb shell it just show

Error: device not found

Please help

I'm currently using. Xperia sp c5303
[Sony Cross-Device General] p5auser:
*#*#8778#*#*,nothing will happen but just do it and follow the op procedure step by step.

I think "abd she'll" should be performed at PC side via USB cable. Don't type "abd shell" command if u type the command at ur phone.
[Sony Cross-Device General] ahrion:
Does this process need to be repeated after a wipe or reflash of a rom?
[Sony Cross-Device General] p5auser:
[MENTION=4567742]ShiAili[/MENTION], hoping you succeed enable B28 and work normally. I am waiting to use your experience and apply it to my Z1C.
[Sony Cross-Device General] BobbySteel:
Shifting the bits so the rightmost one is band 1 instead of 0 makes no difference to me. No LTE either way.
[Sony Cross-Device General] rudyo78427:
sorry for the delayed response. been traveling overseas. I only used it to view the bands that are default active from verizon. I didn't enable any features as I didn't play with settings. I don't want anyone to brick their device. I need to get a new HTC phone to play with and experiment. I will post updates when I do.
[Sony Cross-Device General] sshark:
Are you trying to use Verizon phone on either ATT or T-Mobile network?

Also, are these bands specific to these network?
[Sony Cross-Device General] coglyostro:
I bought my phone in Canada, and it's the same sold in US, the main difference is that it was locked for Bell Mobile, but I unlock it.

I came back to Brazil and the frequency for 4G/LTE here's 2600Mhz band 7.

Is there the same phone here with only different name - ZL to ZQ - and different frequencies of operation.

The ZQ model is the same ZL model from Europe that differs from the ZL US/CAN that I have (confusing I know).

What I need is the original values from either ZQ or ZL (Europe) to see if it works to activate these band/frequency.

In my case I think there is something more to change other than those values, because even the drive for the COM port is different for my phone (MI_05 instead of MI_04).

I tried to activate averything (every band) and the phone try to connect but it doesn't stick and it keep trying until the phone reboot itself and start all over again.

I'm willing to try anything, so if you have any advice.

Cheer
[Sony Cross-Device General] sshark:
Unfortunately I am in the same boat. I have Verizon (CDMA) LG G2 that I am using on the ATT network.

I can see the #6828 and #6829 values but for some reason they don't stick.

I am also trying to find default values for LG G2...
[Sony Cross-Device General] coglyostro:
So the only thing we can do now is wait and see if someone give us these values to try.

I'm out of ideas. Unfortunately....

Cheers

NOt sure what is not working.
[Sony Cross-Device General] BlackSoulxxx:
Verizon/ LG U+ phone will revert 441, 2954 and 946. However 1877 and 6828 will stick and works. Tested with 2 Verizon/LG U+ phone with confirm working unlock LTE band but no CDMA.....

if i update my firmware, need i re-unlock the phone again? [MENTION=4300205]olokos[/MENTION]
[Sony Cross-Device General] BlackSoulxxx:
To make these apps works, you must flash the customize country ROM that support that apps. Like mine, no TrackID, TV Sideview, bla bla bla

After flash French ROM, I can use it normally

About baseband, it's like open door of locked signal that blocked by Sony to suit with the country they try to sell it. You hear about TD-SCDMA version? Japanese version? :D:D
[Sony Cross-Device General] Jeik:
What does this do??

I am a noob when it comes to telephony programming and details. xD
[Sony Cross-Device General] BlackSoulxxx:
LOL I think you are modder/developer so you should understand that

It's unlock band in your phone that Sony lock it to suit with the market they try to sell it. And to use the phone anywhere in the world without worry about your phone is working with the signal in there :p
[Sony Cross-Device General] Jeik:
But wont calls,teyxt and internet go to raoming mode if I am using it oin another country.So this basically enchanches the signal capabilities,or sim unlocks?
[Sony Cross-Device General] BlackSoulxxx:
Xperia lines do not have sim lock version (I think)

About 'sim unlock" some of the point are true. Like use AT&T version to run Verizon band with verizon sim because they are in different band. Normal phone cant works normally without any trouble

And this is "basically enlargenes the signal capabilities" as you say it...

Works on UB and LB too

Maybe you can give it a try

It's like international phone, you just put the sim of the carrier you want to use and enjoy it.

Sorry for my english :p
[Sony Cross-Device General] Levered:
Nice tutorial
[Sony Cross-Device General] Jeik:
Well i will try,but the fact that i would be able to use other sim cards would mean that my phoe should get sim unlocked,and that i could finally unlock my bootloader.I cant use SIM cards from other providers than the one i bought the sp from(it says "card is locked" even tho i typed the PIN in),at the moment.

So many steps,my brain is having a meltdown xD
[Sony Cross-Device General] BlackSoulxxx:
Wait....why dont you buy unlock code....I do this before :p

About safety recovery, just flash baseband from full ftf
[Sony Cross-Device General] Jeik:
I am 16,so i cant use credit cards,so online code purchasiing falls out,and I dont want to waste money.My Xperia Mini got SIM unlocked in the moment I unlocked the bootloader,and on the SP I must SIM unlock the phone for the possibility of bootloader unlocking. :silly:

SONY is so funny xD
[Sony Cross-Device General] BlackSoulxxx:
LOL you have bitcoin address =$$ xD And unlock code is cheap now. I buy once for 10$ to unlock my A (ZR Japanese version)
[Sony Cross-Device General] Jeik:
I added it recently for those who want to donate if they insist xD

I really had some thought-outs about that too,but if I already have a bitcoin adress,might as well let others donate if they think that i deserve it.Il download the packages and try this as soon as i get back home.

Cheers :D
[Sony Cross-Device General] olokos:
You actually can. At least in Poland if you're 16 then you can get a credit card if your parents agree. Mine did and it's really useful. Not only for online transactions. :)

Nobody has ever donated to me even though I did so much stuff, lucky you :P

[MENTION=5733862]BlackSoulxxx[/MENTION]

Could you please remind me what phones/devices have you already tried this on? I'll ad them to the first post so we would get a bigger confirmed devices list, I know it should work on every qualcomm device, but some people just are not going to do that if that's not tested on their device. :)

BTW. I think I might actually try to unlock even more bands and take a look what else is there in QPST by myself later on :D
[Sony Cross-Device General] BlackSoulxxx:
Every sony device on my sign, except arc s and i have to mod every driver for every phone to make works. :p

You read about Z2 lte band that i mention in this thread? I think i just did it.....:p
[Sony Cross-Device General] Jeik:
I have friends who have paypal,but i dont feel safe by not having my own paypal account.

I mainly want paypal for ebay :D

I cant open adb on w8.1 for some reason,on w7 i would just right click on adb folder,and it would give me option to turn a command adb window on...Il try redownloading SDK,it might be that i reinstalled w8.1(even tho i installed all drivers again)
[Sony Cross-Device General] erick_shadow:
and went back to reinstall everything and still the error

any solution? please
[Sony Cross-Device General] olokos:
You can always PM me the details on how to mod those drivers and I'll write down the guide on the second post :)

You can always create yourself a paypal account. I did that before I was even thinking of getting a debit card. I mean real one, payments worldwide, no limits, apart from daily ATM withdrawal and unability to get a credit. (getting negative amount of cash in the bank)

You can always just navigate to the adb folder using "cd" command. On windows 7 to popup a cmd on a directory you also have to hold down left shift while right click. That's what I always do :)
[Sony Cross-Device General] ArtDC:
I tried it on my Xperia TL (LT30at) running on JB 4.3 (Ultimate BlackXT). The protocol went through smoothly, although I did not see the LTE bands selection options. I selected all GSM and WCDMA, and did see all 10 UMTC bands in Service Info. The problem is that the phone reboots as soon as trying to connect at GSM or WCDMA. Connects fine w/o rebooting to original LTE (AT&T here in Wash. DC). No reboot if SIM removed, too. So I just flashed the original baseband and it's back to where it was, an easy fix if something goes wrong, indeed. Any idea what might be causing reboots on connection attempt? Also, I'm interested in LTE bands, especially in European LTE 3 and 7. Anybody ever succeeded unlocking these on LT30a?
[Sony Cross-Device General] BlackSoulxxx:
Can you dial *#*#8778#*#* ? Also you can read it from Start Client -> Service Programming in QPST Configuration?

---------- Post added at 01:01 AM ---------- Previous post was at 12:58 AM ----------

LTE band in this time are unlockable but we just need the RFNV from SO-03F to make it works. So pls stay update............. :D About reboot when connect to GSM,WCDMA network. I think is your device. I have try it on my phone and it's still able to connect GSM/WCDMA/LTE without trouble

[MENTION=5169444]RyokoN[/MENTION] I have one now (SO-03F). Can I use what tool to read and write RFNV to phone, QPST at this time is not useful :(
[Sony Cross-Device General] erick_shadow:
when I type * # * # 8778 # * # * does nothing

I repeated the procedure with no result

install everything and went back to the same
[Sony Cross-Device General] BlackSoulxxx:
That's mean your phone is refuse to connect with QPST. Do you have root access?

Now restart your PC. Uninstall the driver and do:

1. Dial *#*#8778#*#* (If you put it in the number is dissappear, that's normal. If not, you can skip this step)

2. Make sure you turn on USB Debugging, plug into PC

3. After your PC is recognize the phone. Use adb cmd to type this

adb shell
su
setprop persist.usb.eng 1

When you type the code, in your phone there will appear dialog to accept root from SuperSU/Superuser

4. After you type done and accept root, turnoff USB Debugging and wait for 10-15s (No need to unplug usb cable)

5. Turnon USB debugging again and this time you install HTCDiagDriver like the guide show

6. Try QPST now. If the problem still persist, I will have to remote access your PC to fix it. Pls PM me for more detail...

Whatever man! You are a nice guy and all but stop fighting with everyone and keep on making accusatory remarks. Don't take it too seriously. We all are just trying to tinker as a hobby and while doing so help each other out and have a good time.

Don't feel obligated to reply to every message and then say that other person has trying to find easy solution and/or shopping around for one. If you can't/won't reply somebody else will...if not, either question will go unanswered.

[Sony Cross-Device General] coglyostro:
What's your problem?

You come here saying that people did or did not do the procedures, just because it did not work.

Not every phone is the same, and this was repeated numerous times here.

You come here saying people are trying to prevail but who is trying to prevail here is you.

Stop treating others as ignorant, because the only thing you're doing is keeping them away from here with your rudeness.

You did the same with me, and I replied trying to explain what had already been explained, but it seems you decided not to read my comment completely and moreover cited only the beginning of what I wrote and took it personally saying I wanted to prevail with my thoughts, and I've apologized if maybe something I've written has caused a misinterpretation, but you do not answer whether understood or not.

I lost at least two days trying everything including what you told me and it did not work, but that doesn't mean that I haven't tried.

And just to be clear, I missed those two days because I wanted to and not because someone told me to do it.

So you better calm down and stop attacking anyone who says that your method did not work or trying to be superior with your answers.

Everyone here is learning and not trying to "prevail" as you insist.

The above friend tried to answer without being rude to you and also thanked, but apparently it is not enough for you.

Your interpretation was that he does all things by half, even draw your attention, and all that, to look like you have the reason and he don't.

Next time, try to be humble and don't judge what people have or not done based on what they said, sometimes it's hard explain everything here, so if you want to help and have doubt and need more details, I'm pretty sure they will give to you, and will accept any advice.

If you think is not worth answering, let it go.

Someone else will do.
