Hi, we just switched from US Cellular to Verizon, and apparently Verizon does not allow users to select just CDMA like USCC. The Verizon network is also very weak here in Maine it appears (much to my chagrin). We have so many dropped calls and dead spots is laughable - if you were not pissed anyway. I'm wondering if the difference between carriers that supposedly share towers, is that on USCC I stayed on CDMA for the improved data speeds and stability, and because it yielded better battery life due to the 15dBm stronger signal.
I'd like to switch us to CDMA and test it, but the android hidden dialer code does not work on the Note 4, but does on my MXP. Is there a way to switch to CDMA?
Thanks in advance,
Moose
Try this one, but not sure if it will work on your phone....
UE Setting Protocol Menu
[2] NAS
*#0011#
then on the top right (three dots) press it, then select BACK, then press three dots again, and select Key Input, on the next screen, you type Q0000 (capital Q and four ZERO's)
Wait a few seconds, then select the following from the succeeding screen:
[2] UE Setting & Info
[1] Network control
[4] Band Selection
Then select WCDMA Band, then exit and reboot
First want to put it out there that you do this at your own risk
I love that T-mobile has Band 12 LTE coverage but for me the data speeds on Band 12 are horrifically slow, so I prefer my phone to be on Band 4 LTE (at least while at work).
I used to do this change all the time on my S6/Edge and the steps are vary similar to do them on the S7(slightly more involved).
To start with, if you mess with bands, it can(and probably will) affect some sort of your service
So to change network bands you have to enter the service menu. To do this, go to the phone dialer and enter
*#2263#
Once here you will see a screen saying ServiceMode followed by various options
To turn off Band 12 choose LTE Band Preference (#4 on the list).
Then hit next page until you see Band 12 and deselect it (this will remove the * from next to it).
Once that is done, in the top right you'll see where it says "More" select this and choose "Back" - do this until you get back to the main page
Now back at the "Main Menu" choose "Apply Band Configuration" (option 7) and you're done.
Once you exit the menu(by hitting either home or the back phone key) you'll lose signal for a second while the phone switches the bands around.
To revert back to normal, enter service menue *#2263#, choose "Select All Bands"(Option6) and then Choose "Apply Band Configuration" and you're back to normal
Hope this helps someone
EDITed the info above so that you can turn off just Band 12 and keep calling features
Updated the instructions, figured out how to make the phone stick to Band 4 and still retain ability to make/receive calls
Oh Ya band 12 is terribly slow. At least when compared to band 4. Band 4 is wideband at 20x20 20mhz bandwidth while band 12 is 5mhz bandwidth. It's just barely enough.
I was wondering why my speeds suck since I've upgraded to a new phone guessing this is why
Do you have any approximations of the speed difference between the bands, like with speedtest or something?
I didn't notice any difference in speed with my tests was really hoping for better. I'm only getting about 15-20mbps now I was getting between 60-80 about 3 months ago

[GUIDE-WIP] Unlock 3G/LTE bands your LeEco Le Max 2 & fix USA Band selection issue
When people received their X829 (without the B20 support), they realized that unlocking bands does not work in this way for this device. Some are working at the moment to figure it out. Until then, only fixing USA band selection will work. Thanks for understanding and sorry for any inconvenience caused.
Hi all,
After getting into some trouble with accidentally selecting USA Band in "Select Radio Band", I started to search for help on the forums and read a lot. Below you will find an easy way to unlock additional bands on your device or fix the issue of improper band selection.
DISCLAIMER
Given that maybe nothing will happen to your warranty or there are small chances that your device might get bricked, I feel the need to say that I am not responsible for any damage caused by following these instructions. Any modification that you do to your phone you're doing at your OWN RISK.
The steps are quite easy to follow and the instructions are made for beginners and for those who don't know ADB commands (I am one). There are plenty guides out there I should say, but this one is adapted to our Le Max2 and I need to say that it WILL FIX the USA Band selection mistake that some might do
Lets pass to the instructions:
1. Make sure your phone is rooted and you have SuperSU installed, ADB drivers installed
2. Download "Setup DFS Studio" from http://cdmatool.com or the DFS Studio 16.05.31.0 (an older version) from here https://mega.nz/#!h1ImHJyK!gBcp2j6wIp6e6smNvwuQ-GvxNTL6mYSoIjPkY_hJJVY
3. Connect the phone to the computer via USB
4. Select MTP and USB debugging
5. Open command prompt from Start => Run and type "cmd.exe". Once opened, type "adb shell". It should show "[email protected]_x2:/ $"
6. Open the SuperSU app on the phone
7. Type in cmd.exe "su" and grant access of ADB shell in SuperSU, you will see "[email protected]_x2:/ #"
8. Type in cmd.exe "setprop sys.usb.config diag,adb" and your phone will enter into Diagnotics Mode - this means that the MTP connection will be lost (you won't find any portable device in My Computer).
9. The drivers should be installed for the Diag Mode (in my case automatically - Win7 32bit) and you can see in Device Manager at Ports - Qualcomm HS-USB Android DIAG 901D (COMxx).
10. At this stage, if all should be well, you can start the "Qualcomm Tool" from DFS Studio folder. You can close the login window and it will run in demo mode (enough for what we need)
11. In the "Main" tab, double click on "Qualcomm HS-USB Android DIAG 901D (COMxx)" to select it - in the DFS log you will see "Qualcomm HS-USB Android DIAG 901D (COMxx) device in diagnostic mode"
12. In DFS Tool select tab "Band"
13. In tab "CDMA/GSM/HSPDA" select "RF BC Config" and then "Read"
14. Select the bands you need and then press "Write"
15. In the same tab, select "Bands Preffered" and do the same as above (read-write)
16. Select "LTE" tab which is aside "CDMA/GSM/HSPDA" and do the same as above. I changed values only in "LTE BC Config #6828" as the "LTE BC Config DIV #6829" didn't work for me when I pressed Read (there was nothing selected, all blank).
17. After operation had been completed, close Qualcomm Tool, unplug the phone and restart it.
Notes:
1* At point 9 if the drivers do not automatically install, search for HTC DIAG DRVIER and change the .inf file and install them manually
2* To exit the diagnose mode, just unplug the phone from the computer and it will return to normal on the next connection. Kindly note that during the diagnose mode, the phone will be in "Charge only" state.
3* To make sure that the procedure is successful, do the steps once again and press only "Read" after the restart to see that the bands are indeed added.
4* This guide might be used for any Qualcomm device as long as it can be entered in diag mode.
5* To fix USA BAND Selection issue, it is necessary to select in "Band Preferred" the same bands as in "RF BC Config" and then write them.
6* Some might think that if they will select all bands, then the phone will work also on the Moon/ Mars. Well, that's not the case... I'm not sure what antennas are within the handset itself and if it will be able to work on different bands than specified by LeEco, but one might give it a try.
Original bands of the Le Max2
2G: GSM 2/3/5/8; CDMA (BC0 / BC1)
3G: WCDMA B1/2/5/8; TD-SCDMA: B34/39; CDMA (BC0 / BC1)
4G: FDD-LTE: B1/2/3/4/5/7/8/12/17/20/25/26; TDD-LTE:38/39/40/41
FAQ:
1. Will it work on my device? A: The tool is only intended to be used on Qualcomm devices, it won't work on Exynos, Mediatek, etc...
2. My device has a Qualcomm processor, can I unlock additional bands? A: In theory yes, but the hardware matters the most. This tool is just to unlock the software side.
3. I have unlocked band 20, why doesn't it work/connect to a network? A: As stated above, this depends upon the phone's hardware and antennas. Nobody can guarantee that if you'll unlock a specific band, then the modem will connect and operate on that band. The phone needs to have all the necessary hardware in order to operate properly but to only be limited on the software side - this is why we use this tool
4. What phones have been reported working until now? A: Why don't you give it a try and write down your feedback here?!
Credits for this goes to chatmonchy who actually gave me the idea to restore the preferred bands; the various guides for a lot of Qualcomm devices that can be found over the web; XDA community.
I am wondering if this is needed for Indian variant which already supports the above list of LTE bands? In India, they are using only 3 LTE bands. B3, B5 and B40.
Well, for sure not in your case. If you travel a lot, then you might feel the need to change something. I saw over the forums that some people ask about the bands supported by the phone or some complain about not having signal on some networks, then at least they should check what is enabled in their device.
I noticed that on Indian ROM when you enter *#*#4636#*#* in dialer and you select Phone information and then Select Radio Bands, there is nothing to select. Can you confirm please? On the Chinese rom the options are "USA Band" and "Band 6". Selecting any of these will break the preferred bands in Le Max2 resulting in loss of network in Europe or somewhere else.

You are right, on Indian 15s firmware, there is nothing to select under Select Radio Bands in testing menu.
Any way to check the LTE-A/4G+ support with this method?
Thank you soo, soo much for this solution. A life-savier. Setting the band-preferred worked for my LeEco Max 2.
I tried step by step but after completing there is no extra band options in band selection I.e *#*#4636#*#*, log says nvwrite complete.
thread: [GUIDE] Unlock 3G/LTE bands in your LeEco Le Max 2 & fix USA Band selection
Hi, gyus
I had the same problem, i select USA band and everything went wrong,
The simplest way for me was:
installing "X820 LeMax2 RevolutioN_Team Resurrection Remix", no other from TeamSpain, only Resurrection Remix
http://revolutionlemax2.blogspot.al/
https://mega.nz/#!T9o0wAhJ!iLa9mrPAr5wObvygnF5giyioUnJKnVkCg3_L-q2RgnA
then after installation, go in dialer and call *#*#4636#*#*.
There are three band: Automaic, USA, and EURO.
I select the EURO and everything i'ts OK.
BEFORE DO ACTIONS DON'T FORGET TO BACKUP ALL THE ROM WHERE YOU ARE WITH TWRP

Generally shouldn't be any visible changes in there. The change you will see if you will have a network working on a different frequency than it was phone's default. Also DFS will show at next connection what bands are enabled.

Thanks, good to know. I think it would have been better to select Automatic and not Euro, despite that you may live in Europe, if you will travel outside or you will sell the phone, it might not work anywhere else except Europe. Maybe I'm wrong...

Okay, i didn't think it, you can select Automatic without problem and the band will return.
I don't know why, but in this ROM the selection band have change. Not have more Euro band and in his place are Japan and two others, but the Automatic and USA are there, no problem

This link is CM13 modified by TeamMSpain [RR] ResuRRectioN RemiX LeMax2 x820 RevolutioN_Team (the name of the ROM: RR TeaMSpaiN RevolutioN FINAL) and is good ROM, but have problem with recent button, not have RemoteControl and CallRecorder app, but you can record manually when you call and the recorder you can find in FileManager. After installation you can type in dialer *#*#4636#*#*. Click Phone Info and after in dot menu click the select radio band. There are the bands what's your needed. But the Automatic is for all us LeMax2. Don't forget to Backup the ROM where you are now.

I am in Canada using Wind Mobile. Is there any advantage if I pick USA bands? Can I switch back to prefer bands if I want to? Thanks

It's possible that you might not get any signal although I'm not sure about Canadian networks if they have anything in common with USA ones. In Europe won't work, this is for sure.
You can try selecting USA Band in the dialer. To restore you have to follow the procedure in the op.
Sent from my Le Max2 using XDA Labs
I added the bands for Japan that I need (especially 800mhz for 3G in rural/mountain areas, and a couple of the lower frequency LTE bands my carrier uses). Although the Qualcomm tool on the computer reports them added, and I am given the option to select Japan bands on the phone, they don't seem to make any difference to my reception - they should improve reception in mountains and inside concrete buildings, but they don't whatsoever. I see no change at all and am therefore sceptical if the modem hardware is actually capable of accessing these bands even if they are turned on in the firmware.
Is there any harm in enabling every single bands? I know most of them won't work but there is no way to really tell which ones will work and which ones won't. And as long as there is no harm in enabling them all I might as well try it. Has anybody tried enabling them all?

This is why it's written in the op that the phone maybe does not have the hardware capabilities. This is like the first confirmation that it does not work, although we should see if more people claim it not functional.

I have enabled all the WCDMA bands and there is no problem with my unit. I can't guarantee for yours, but I don't believe that will happen something.
Well, was no harm in trying anyway.
Does anybody tried this phone to Sprint?

It has LTE bands for Sprint, but I do not know if the Sprint store can add it to its whitelist and let it work.
This is basically the same as my post for the S7/S7E - looks like the dial codes still works on the S8
My original thread
https://forum.xda-developers.com/tm...ng-network-t3331555/post65722081#post65722081
First want to put it out there that you do this at your own risk
I love that T-mobile has Band 12 LTE coverage but for me the data speeds on Band 12 are horrifically slow, so I prefer my phone to be on Band 4 LTE (at least while at work).

To start with, if you mess with bands, it can(and probably will) affect some sort of your service

To revert back to normal, enter service menue *#2263#, choose "Select All Bands"(Option6) and then Choose "Apply Band Configuration" and you're back to normal
Hope this helps someone
Interesting, How many others here find the need to change bands?
Wonder if its many, which case wonder what Tmobile would do to fix that.
Is there a way to determine the current band (LTE/UMTS) that I am using with a stock phone without root? I tried the service menu (*#lgmenu#*910#) but I don't see any options available to select LTE band.
I don't know about the H910, but on some variants, in the hidden menu, you go to Field Test -> Modem Settings, and you can see an LTE Band Selection menu there. However, if there is no reset option, then I don't think it's safe to mess around with the bands there since you could be stuck on a single LTE band.
For checking what current band you're on, you can use one of those network signal analysis apps like LTE Discovery, Network Cell Info, or SignalCheck. Their main functions should work without root access.
