[Sony Cross-Device General] dennis5pia:
No, is not useless. I thought you had checked the first post where the steps are.

But making it simple. You need QXDM to set the bands on your phone.

So, you calculate the bands with the calculator then with the phone in DIAG mode, conected it to your PC, open QXDM, select your phone port and scroll to the item numbers, click read, change the values for the ones you got with the calculator, then click write. When finished, click restart or reboot your phone manually.

Remember to save the original values, in case something go wrong.
[Sony Cross-Device General] dennis5pia:
I'm gonna show you and example with the LG G4 US991 from US Cellular. It has the exact GSM/WCDMA bands you want to enable in your phone.

You can check the bands here:

http://www.lg.com/us/cell-phones/lg-US991-Metallic-Gray-g4

...Item 01877 shows: 562950035735431

NV Calculator shows: 562950035735424

That's because the US991 is a global phone, so it supports CDMA/GSM/LTE and the NV Calculator does not support CDMA bands calculation. You need "mzTool" to calculate CDMA/GSM/WCDMA bands or simply add 7 to the number you get with NV Calculator for adding the USA CDMA carrier bands.

You need QXDM to modify bands. Once you have your phone in DIAG MODE, connect it to your PC, open QXDM, go to options>communication, select your phone port and click OK.

Then NV Browser. Open catogory filter and choose CDMA, Scroll to item 01877, click read, write down your value, then input the value you get with NV Calculator or mzTool, or the one I gave you, then click write.

Open category filter and selecte LTE, read item 06828, write down your value, then input: 549756338373 for bands 1, 3, 7, 8, 20 & 40. Do the same with item 06829. Then restart your phone.
[Sony Cross-Device General] ViBE:
so as i understand you what i have to do is to modify 06829 & 06829 values to 549756338373 and save. thats all? how can the results btw?
[Sony Cross-Device General] dennis5pia:
Yes, but those items are for LTE. If you want to modify GSM & WCDMA you have to modify item 01877 too.

And modifying/adding bands does not guarantee they gonna work. Hardware must be present in phone in order to work.
[Sony Cross-Device General] ViBE:
yes i would like to. but i have no clue what are the exact bands. too much of them. what i know is that i want the mentioned freqs what i wrote down before.
[Sony Cross-Device General] dennis5pia:
I told you, you can use NV Calculator to calculate bands or you can just set the value I gave you. It include all 4 GSM bands and WCDMA 850/900/1900/2100

01877: 562950035735424
[Sony Cross-Device General] ViBE:
ah, many thanks for your help. now i have to test it somehow. are there any apps for figuring out what freqs the phone use actually when using an LTE network?
[Sony Cross-Device General] dennis5pia:
Entering in the phone "engineering mode". Try LTE Discovery, but that app works by collecting data from user, so depending in your country it may show nothing.

I thought you wanted to enable those bands because your carrier uses them
[Sony Cross-Device General] ViBE:
yes but my carrier use several freqs so it's a bit difficult figuring out is my phone capable for B20 for example.
[Sony Cross-Device General] dennis5pia:
According to GSMArena your phone supports B3, B5 and B40 out of the box.

Where are you from?
[Sony Cross-Device General] ViBE:
yes but they also released International version and the chipsets specs say that the chip capable. so i guess they just unlocked the non-International while it's the same hardware. Hungary btw.
[Sony Cross-Device General] dennis5pia:
Have you tried LTE Discovery?

Try this apk

https://docs.google.com/uc?id=0B9wv54tzMZsAblUzS21VU3Zfa2c&export=download
[Sony Cross-Device General] ViBE:
i already installed LTE DIscovery but it's not clear what the hell it shows. also no way to check the actual LTE bands, so....

another problem is that my phone started to act strange after modifications and i have no clue why. since the modification it's usually use 3G indoor and IF i connect to wifi/mobile data it shows 4G(???) while it's still not use 4G as LTE Discovery say. and if i switch off wifi/mobile data it goes back to 3G and don't want to use 4G just outdoor while the coverage is far enough...
[Sony Cross-Device General] dennis5pia:
Sorry for late reply..

Uhh. So what did the phone show before modifications?

Some phones shows 4G while they are connected to H+.

According to GSMArena your phone supports B3, B5 & B40 out of the box. With your modifications you omitted B5 is there a change your carrier uses B5?
[Sony Cross-Device General] ViBE:
my carrier using 7 and 20. the phone shown correclty before i modified. it's now showing 3G while before modification it usually reach 4G. now if i switch on the wifi or connect with mobile data it shows 4G...BUT LTE Discovery says that it's IWLAN and LTE is N/A. so i have no clue what the hell happened and i'm really disappointed about these calculations/calculators and the methods.
[Sony Cross-Device General] dennis5pia:
But if your carrier uses LTE B7 & B20 and the phone doesn't support those bands out of the box it couldn't connect to LTE on those bands before.

Maybe it showed 4G but was H+. Just set back your original values and test.

This instruction is only for unlocking GSM (2G) and WCDMA (3G) netwroks.

You can compare it with unlocking LTE at Samsung Galaxy or OnePlus One

For Sony Z5C not enough change in QXDM, as the file amss_fsg_suzuran_***_tar.mbn does the modem configuration.

Clarify:

* Added new ranges, but in the end only one of them added;

* When you change SIM-card (operator) restores the default ranges.

There is a hidden activity for it. It's called "Customization Selector/Modem switcher" and you can find it with various shortcut managers, I'm using Quick Shortcut Maker for this purpose. Just open the ACTIVITIES tab and search for "modem". Only the right one will be found.

BUT: Normaly it won't run, you need to edit build.prop and change the "user" build type to "userdebug". After that it will be startable (just make a shortcut or do "Try" in QSM).

WIth regards,

Step to unlock LTE band 19.21 in Z2 D6503, SO-03F (Yeah it have band 19,21 but need int' band)

Install QXDM http://www.mediafire.com/download/r1z2r6iu94habrp/QXDM-3.12.714-www.getdriver.com-.rar

Do the guide and unlock all, include "[60] Reserved for BC10...."

Write NV to phone

Do to step 33 then stop

Open QXDM, go to Option -> Communication

In Target port, choose your phone com port and press OK

Now in View -> NV Browser

QXDM will open new window, in Category Filter choose LTE

Scroll to id 06828 and click on that, click read then in Input and Value change the value to "1904863" (The value of int' Z2 with LTE band 19,21 add)

Click "write" and do the step 34 on the guide till the end

Reboot the phone, and check 7378423 to see the band

Works on Z1, Z2

I also have your problems but it's very long times ago, when I start to research this from Qualcomm documents and it dissapeared. Can you install driver? Does your phone have weird behavior when QPST is not turn on? Restart PC and phone? And can you put the phone into debug mode (I think....) by *#*#8778#*#*, turn on usb debug and set to mtp mode, plug into pc, type adb command, turn off usb debug (not plug the cable out) and turn usb debugging on again?

And I think you didn't put your phone in debug mode and watch their hardware ids because in debug mode and usb normal mode their hardware ids and function are separately

---------- Post added at 10:40 AM ---------- Previous post was at 10:28 AM ----------

For all with error "exceptionthrown" error, try using QXDM and search for value 1877 and change it. I didn't test this yet but in theory it should works......

---------- Post added at 10:46 AM ---------- Previous post was at 10:40 AM ----------

No, in logic the phone cant reset it because it's in partition that the phone was put in read-only mode. Only access able by Qualcomm tool........ So did you press"write nv" then in file -> Write changed NV to phone" ?

I have tried the guide on my Samsung Galaxy Tab S 10.5 LTE (Sprint).

I could wirte the NV_RF_BC_CONFIG_I (#1877) value in RV_NV_Manager.exe but my problem is:

When I'm in mzTool selecting my WCDMA bands (I can't see LTE bands, just GMS/UTMS/WLAN, etc), there are other 3 values that are being modified:

NV_BAND_PREF_I (#441)

NV_BAND_PREF_16_31_I (#946)

NV_BAND_PREF_32_63_I (#2954)

I can see the NV_BAND_PREF_I (#441) in RV_NV_Manager.exe and modify it like the #1877 but there is not present NV_BAND_PREF_16_31_I (#946) nor NV_BAND_PREF_32_63_I (#2954) then I can not write it values.

There is not #6828 nor #6829 (LTE preferences) parameters either but I can see LTE config, settings and more for this carrier under Hidden Menu...

Am I missing something?? :confused:
