I saw a method of getting msl code via cdma ws 3.5. I am using 2.7 and am wondering if the proccess is the same or can i even get code with older software.
Evo 4g 2.3.3
Ok, I opened chat to sprint support and asked for msl code. They told me that my device doesn't have MSL but then gave me what they called a 6 digit security code to reprgram my phone. Is this security code the MSL and they just didn't want to tell me.
This method is only known to be working on VZW M8's.
I WILL NOT BE HELD RESPONSIBLE IF SOMETHING WRONG HAPPENS TO YOUR DEVICE BY FOLLOWING THIS GUIDE!
Before proceeding ahead Just check which bands your service provider uses and note it down somewhere.
(Since there are many people out there who have asked about jio or other indian carriers, for their convinience i am writing a short note : In india Reliance Jio is using band 3,5 and 40 and airtel is using band 3 and 40. all other carriers are also using these three frequencies only i.e. 3,5 and 40. I am no longer using my verizon m8 currently i have an indian galaxy S7, but when i was using my m8 i was able to connect to band 3 using airtel, i also tried using jio but it doesn't work at least for me.)
Steps To Unlock The LTE Bands :
First of all ensure you are on stock verizon rom.(Its Really Easy to Enter Diag Mode On Stock Verizon ROM)
if not use an RUU from this thread(use the latest one.):-HERE
Install HTC Sync Manager on your PC before proceeding ahead, by putting your phone into install mode.
Now once you have flashed the ruu or you are already on stock verizon rom and also installed htc sync manager, Follow these steps :-
1. Download DFS Tool
2. Skip this step if you are using a CDMA SIM.
Put your phone into cdma mode by going into Settings>Mobile Data>Network Mode>LTE Only Mode. Enable USB debugging as well.
3. Open Phone Dialler type on the Dial Pad ##3424# and press call button. Phone Should enterr into diag mode. If you are on marshmallow firmware phone will ask for MSL code, Here it is - 000000(6 times zero).
4. connect your phone to the computer and install DFS Tool You just downloaded on your computer.
5. Optional : Create an account on this website - https://www.cdmatool.com/
6. Open DFS tool and login or just skip the login if you do not have cdmatool.com account.
7. Now you will see your m8 listed as PORTXX(X - Refers to any number between 0-9) in DFS Tool. Double click on it.
8.On the DFS Logs window you should read something like device connected.
9.Now in main DFS Window click on Band Tab, then under the bands tab you will see two tabs, HSPA and LTE click on Latter one.
10.Click Read.
11. Select the LTE bands you need.
12. Click write.
13. Restart Your Phone Once.
14 Put It Back Into GSM Mode/CDMA mode depending on your network provider.
For Stock ROM Users Only/Custom ROMs Based on Verizon stock ROM/Still Not Getting LTE
1.Download This APP
2.Then Select GSM/WCDMA/LTE auto in the App
Still not getting LTE?
Reset phone through stock recovery(4.4.X reccomended.)
Test for at least a day and then report back by either participating in the poll above or replying below.
Is this permanent for the phone? Will it be the same after I flash any other custom roms?

Flashing a rom shouldn't change it. It would only change if you flashed an RUU or flashed just the firmware for the phone.

Yes it should remain as is no matter whatever ROM u flash.
As far as firmware flashing is concerned i will get back to you on that one.

You might not be having that good 4g reception in your area. That can be the most probable reason. Try using your SIM in some other 4G phone and tell if the same thing happens.
I tried this on my GSM-unlocked HTC One M8 (w official marshmallow installed), but I can't seem to get into the diag. mode. I was asked for MSL code after I type in ##3424#, but I don't have the MSL code.
Anyway to get MSL code or get by this one? Do I have to unlock the phone to do the steps as in OT? Mine is still locked and S-ON.
Your help will be very appreciated.

'##3424#' wont work on GSM M8.
You will have to enter diag mode by different means.
Try this code-
HTML:
adb shell
su
echo 1 > /sys/devices/virtual/android_usb/android0/f_diag/on

After you are done with unlocking bands use this code to disable diag-
HTML:
echo 0 > /sys/devices/virtual/android_usb/android0/f_diag/on

I flashed MM radio on my verizon m8 and I am still getting LTE. So firmware flashimg will not relock the bands.

Great! I'll give it a try tonight. Hope it'd work. I don't really need or want to root my phone, I just need to enable the LTE bands in my country (Singapore).

Remember usb debugging should be turned on.

I did enable usb debugging.
Tried your code, but adb gave me the following:
system/bin/sh: can't create /sys/devices/virtual/android_usb/android0/f_diag/on: Permission denied
Does this mean I have to unlock and S-OFF my phone?
When I type in command su, it's not a valid command. I assume su means superuser? My phone isn't rooted, still S-ON.

You will need root access without that it will not be possible to enter Diag mode in your case.
If you have non-verizon m8...why dont you just unlock bootloader via HTC Dev and root your phone. Also you can root your phone with kingroot without needing to either unlock bootloader or S-Off the phone iff you are on 5.x.x or lower as far as i know(Many people having verizon M8 used kingroot to achive s-off via sunshine while they were on 5.0.1).

Mine is a Verizon GSM-unlocked M8, just upgraded to Android M (Verizon version of course) a couple of days ago. I guess I'll have to get the sunshine to unlock and s-off it then.
Thanks again for all the help

If you have verizon m8 then you can unlock bands without root.
You need to go to cdma mode from global mode amd then go to dial pad then ##3424# as it says above in guide........
There is no verizon gsm model but all verizon m8s have gsm built in so that they can support lte, as lte is a different technology from both cdma and gsm but based on gsm.
11. Select the LTE bands you need.

Per Verizon, their M8 supports LTE Band 13 / 4 (700/1700 MHz).
Has anyone had success using this method to unlock bands 2/4/12 for LTE on AT&T/T-Mobile? I'd be especially interested if anyone is successful unlocking bands 3/7/20 for use in the UK and Europe. (I have a very tentative plan to visit the UK and it would be great if I could get 4G speeds while I'm there.)

I can confirm about 2,3,4,7,9,40.
One person has even written that he was succeful to unlock all bands.
Go ahead and give it a shot, 2,3,4,7,12,13,20 are the bands you are looking for....

I tried the ##3424# on dial pad, but was asked to input MSL code I can get into diag mode with #*#*3424*#*# w/o being asked for MSL code, but it's quite different from the mode I've seen after typing in ##3423#
Okay, just found someone said that Verizon CDMA phones usually have 000000 as the MSL code. I tried it, and it worked Now I'd see if I can get the LTE bands (3,7,8) enabled ...

K i will mention in the OP about MSL code thing.....

Hey guys,
I have a situation with my HTC 10. I have unlocked bootloader, and S-off via sunshine and installed Viper10. I recently purchased network unlock codes from HTCUnlockingservice.com but it wouldn't work when I restarted the phone with Verizon sim, so I had to go back to stock T-Mobile RUU. But I have the same problem, when I insert a foreign sim it doesn't promp me to enter unlock codes, instead I have a sim-lock icon in my status bar. The TMobile Device unlock App doesn't work either (it used to say incompatible with Viper10, now it says "failure in processing request. please reboot device and try again").
Can someone help me find a way around it ??
Is there a *# sequence to prompt unlock code entry ?? something like the *#06# is ed for IMEI...
Please help, going crazy over here
thanks

This is an old thread but just FYI for anyone in the future when using z3x unlock by msl make sure on your phone that you have hit dialer code *#0*# before u hit msl unlock. It should then prompt for msl entry which according to vzw tech as of today's date is either 000000 or 123456 or 111111
