You realised you just opened the door for a massive inflow of help requests:)

Are the steps universal or require drivers specific for a model? I got a Korean version of Galaxy S5 SM-G906K and am desperate to unlock LTE band B20... crying for help!
[Sony Cross-Device General] orangek3nny:
Thanks for the drivers and the command, they did the trick. By the way, LG provides an updated universal driver here, currently version 3.11.3.

As far as I understand, it is not necessary to include any other GSM bands than the preset ones, if you have a Nexus 4.

According to worldtimezone.com US uses 850/1900MHz and the rest of the world 900/1800MHz. All 4 are already activated.

What I tried, is to include additional European LTE bands 800, 1800 and 2600. The process worked, but I cannot confirm, if they really work, as LTE isn't enabled in my data plan. Apart from that (with a .33 radio) the connection works fine.

Another question is, if the LTE chip is really capable of transmitting these frequencies, or if it really is limited hardware-wise. I couldn't find a definite answer during my research. However, there are already some posts about changing ID 1877 back in 2012.

In a few weeks I might try a friend's SIM with an LTE data plan and see how it behaves.
[Sony Cross-Device General] Product F(RED):
Europe uses 900/2100 MHz WCDMA and 800, 1800, 2600 MHz LTE. They use 900/1800 EDGE.

The Nexus 4 has Band 4 (AWS) LTE because of a leftover antenna from the Optimus G board (since the N4 is an Optimus G). So not being able to add more LTE bands is a hardware limitation.

Good news !

[Sony Cross-Device General] lfuentes:
Could this work on LG F180L? I tryed steps 1 to 10. but nothing happens on that step :(
[Sony Cross-Device General] orangek3nny:
Thanks for the explanation.

Theoretically, what modifications would a N4 need to work with other bands?
[Sony Cross-Device General] fards:
Ok waiting an explanation :)
[Sony Cross-Device General] Product F(RED):
You can check what band you're on if you dial this number:

Go to Basic Information.

AT&T disables manual band selection I believe but if you want to try, dial *#2263# and choose WCDMA and then 1700 MHz. To undo, hit menu and then press back and choose Automatic.
[Sony Cross-Device General] ejlmd:
Unfortunately, I get an error message when running that code. I have a Moto X (XT1049), originally on Republic Wireless, apparently hardware identical to Moto X (XT1056), with KitKat 4.4.2 baseband and T-Mobile 4.4.3 stock ROM, bootloader and SIM unlocked.
[Sony Cross-Device General] Product F(RED):
No that code is for Samsung phones only. I should have stated.
[Sony Cross-Device General] CHAMAVELI:
I was trying this out as my carrier is Aus uses 850/2100 and thought they may have accidentally disabled 2100 as the the only LTE freq the N4 supports is 2100, but all seemed to check out.

To fully enable LTE you'll need to source an additional radio that supports LTE and the N4 which will need to fit into chassis anyway. You'll also most likely need a custom kernel and one of the modified radios.

I can unlock LTE band Docomo SO-03E (Tablet Z)?

According to your instructions I can not install the drivers at step 13.
[Sony Cross-Device General] updateing:
Tried on my Xperia TX, OmniROM 4.4.4. Original code is 562950069289856. I ticked all the options in GSM and WCDMA, but aftering rebooting the phone won't boot up: when lockscreen appers and the phone searches for signal, it freezes and reboots. In /proc/last_kmsg it says something like "modem: smem_get_entry failed" "Modem: watchdog bite!" etc. Don't know if this phone doesn't support all the bands...Or it's related to the firmware (only stock firmware will accept the changes)?

EDIT: checked a few pages before this reply and realized that only a few bands were accepted on this series (V, TX and T, maybe). My TX has stock support for all these bands...
[Sony Cross-Device General] oksagi:
How you managed to change LTE on non Z2 device? i have m7 and like to do so.

Can you explain your steps?
[Sony Cross-Device General] ejlmd:
Also, LTE bands were not visible under NV item 1877 on Moto X.
[Sony Cross-Device General] BlackSoulxxx:
Sorry for the delay in posting LTE unlock guide. Right now I'm in Sony Service Center and wait for repair my Z1 chip (dead RAM, result of OC CPU up to 3GHZ+ (internal kernel testing) and ram cant handle it :p ) (SoC is below RAM chip, they use PoP solder, IDK)

And I have some information about c6902 when I was talking with repair guy: Actually 6902 and 6903 (dont know if z2 is the same) use same mainboard, circut and antenna design. You just replace SoC, modem, and 2 other tiny chip and it become 6903 (Yep I'm was right at the beginning)

I'm checking this out for myself. I don't know what I'm doing, though, and only looking for options to unlock Spark LTE bands (bands 26 and 41). However, I don't see this option but from reading the thread, there's some other menu or something to change LTE bands - I don't know where it is or I'm misunderstanding what I'm reading. Waiting for the LTE guide to come up and take it from there.

Hi, excellent guide. I was looking something like this long ago as I would like to enable UMTS BAND 8 (900MHz) in my AT&T M7. Unfortunately, I followed every step of the guide and everything was like the description but when I restart the phone, no UMTS 900MHz, if I read NV_CONFIG again I get the original value not the one I have changed.

Those anybody knows if in this case this is read only? Or any other method to achieve this?

Thanks in advanced!

hi i have an HTC One Sprint and i have S-off and everything .... i try the step until these steps

1. Download this zip http://d-h.st/0Me

2. Extract it and install QPST from that zip

3. Open the caller app and type in *#*#8778#*#* (it should go off the screen after you type in the last symbol "*"

3.5 Those on custom roms (tested on cyanogen 11 with s4 mini) can use the efs professional toolkit to change the mode to enable the diag port.(Thanks [MENTION=1140654]blackburn[/MENTION] !)

4. Connect your phone to your PC

5. Open ADB console

6. Type in these commands:

Code:

adb shell

su

setprop persist.usb.eng 1

7. Turn off USB Debugging, Disconnect your phone from the PC

and then i reconnect but recognized the phone normally no other devices to install a Clue how to do it?

how to enable the Diag ports in HTC ONE m7 sprint
[Sony Cross-Device General] gk1984:
I had trouble too, but figured it out (once). Not sure if I can replicate my success yet. But... I found that I had to uninstall the driver for your HTC One from Windows' Device Manager. When you plug the phone in again, Windows will automatically try re-installing the same old driver, though. So you have to cancel the automatic driver install/update when it tries to do it. Then in Device Manager, right click on the Android device and update driver. Choose from a list of devices, browse for Ports (coms/serial) or something similar. Then browse for HTC and install the HTC Diagnostic driver. It might tell you it's not compatible, but install it anyway.

As far as connecting from here, I had to flash back to a Sense ROM and put it in diagnostic mode (it's a little further down on page 1 - a note for HTC devices to use a different command in adb). But it took a little while to finally be recognized in QPST. I got up to do something and came back and the phone was recognized. Not sure how long it took though.

Tried to replicate this on the GPE ROM, couldn't get it to be recognized by QPST. So when the LTE guide is posted, I'm going to be restoring a Sense backup I have and giving it a try.

This is the $64000 question. I get to the same point on my ATT htc one.
[Sony Cross-Device General] gk1984:
If you had read my post just above yours, I had directions. Once you uninstall the Android driver/existing driver for your HTC One and cancel Windows from auto-installing it when you plug in - follow this https://www.youtube.com/watch?v=Yvf6iB8fAT8

I found that, to work with the Xperia ZL LTE Version (C6506), the drive that you supposed to install is for MI_05 ID instead of the MI_04

This way will be possible to read and write commands in the RV NV Manager and QXDM Professional.

Before, I had the same problem that erik_shadow had, that was not possible to read the information from the phone.

I enabled the LTE Band 7 (2600) to work here in Brazil, but unfortunately it doesn't worked, the phone keeps searching for the conection (data/call), and instead stop searching and stay on 3G, it keeps going until the phone reboot itself and start doing again.

I can change to only 3G in settings and it works normally, and even do the steps to revert the changes instead flash the baseband again .

If anyone has any idea how to make it work would be nice.

What's is curious is that, there is the same phone here in Brazil with different name, Xperia ZQ (C6503), and it's exactly the same except for the bands that works.

If someone with a ZQ model can post their decimal numbers from the line #1877 and the #06828 using the QXDM, maybe I can compare then and see if I can make it works.
