Service Menu - ZTE Axon 7 Questions & Answers

Has anyone figured out the hidden service menu with the dialer code? I'm coming from an LG G4 and like to pop in and see what band I'm on. Just curious if someone has figured this out on the Axon 7 yet.

Same. *#*#4636#*#*

Does that give you the band info? I don't have the phone yet. Should be here Wednesday. The G4 is 277634#*#. I get an error with the g4 in phone info with the one you suggested.

Do not see band info on there, sry.

Bummer. Thanks for checking.

To address the OP's question, use signal check pro or lte discovery to figure out what band it's using. The latter seems to give details when signal check doesn't.
================================================
I was going to start a new thread, but this is sort of in line with this.
First, some of the codes here work:
https://cdmatool.ladesk.com/702910-How-to-enable-Diag-mode-for-ZTE-smartphones
Without a sprint sim, not sure if this works, but
##786#
##3424#
The 3424 requires an msl code to make any changes. Normally on an unlocked device it's just 000000, but that doesn't seem to be the case here.
Anyone have any idea what zte uses for a default unlock code? One of the changes that can be made (at least for sprint) is controlling which lte bands the device uses. Band 41 (2500 mhz) is really weak around here. Would be nice to lock it out entirely. Need the msl/spc code though.
Also, how is diag mode (not debug, diag) enabled on this device?

Guide: Enabling LTE Bands

Note: The title of this guide is Enabling LTE bands, but actually, it's for LTE and for HSDPA bands.
This is something near and dear to me, as I travel the world somewhat and really prefer to have only one phone.
I spent all day figuring out how to add more LTE bands to this phone (I have a bootloader unlocked H815, European version, so please understand that it may not work with other versions, and simply can't even be attempted until you can root it.)
The model I own comes with the following bands:
2G bands GSM 850 / 900 / 1800 / 1900
3G bands HSDPA 850 / 900 / 1900 / 2100
4G bands LTE band 1(2100), 2(1900), 3(1800), 4(1700/2100), 5(850), 7(2600), 8(900), 17(700), 20(800), 28(700)
I noticed, however, in the hidden testing menu (277634#*#, Field Test, Modem Settings, Network Mode), the following extra bands, none of which worked:
WCDMA 800, WCDMA AWS (1700/2100)
Along with the following extra LTE bands(277634#*#, Field Test, Modem Settings, LTE Band Selection), again, none of which worked:
Band 12, 13, 25, 29, 40
The result?
Having enabled all of the LTE bands available in the testing menu, I was able to add WCDMA 800 and AWS bands, along with LTE band 40. Unfortunately at this time, Bands 12, 13, 25, and 29 do not work, even if enabled. However, a T-Mobile radio file might help for band 12 if it's a radio issue, or it could be a hardware difference in which case there's nothing we can do. I really don't know until I can test with it. I'm happy about the extra bands, though, because in the US I use T-Mobile, so AWS helps, and in Japan, band 800 is used. Maybe I'll use 40 if I go to China some time.
So how to actually do this?
Step 1: Unlock bootloader and root. You can find out how to do that in other threads.
Step 2: Install the LG USB Drivers. It comes with the LG PC Software.
Step 3: Download CDMAtool from here: http://cdmatool.com/ A free trial works fine for this.
Step 4: Make sure you have adb, and connect your G4 to your PC. In an adb shell, execute the following:
su
echo 1 > /sys/devices/platform/lg_diag_cmd/diag_enable
Step 5: Unplug and re-plug your USB cable. Your phone is now in diag mode (although you wouldn't know any better because you don't get any special device names in Device Manager.)
Step 6: Open DFS which you downloaded from CDMAtool.com Deal with making an account, etc. as you have to get into the software. Close the account window and the actual software will launch.
Step 7: Double click your device to put a checkmark by it in DFS.
Step 8: Click the Band tab. Choose RF BC Config at the bottom. Then, choose read.
Step 9: Make sure your bands are displayed. Check the extra bands you want to add. I recommend against enabling bands other than those mentioned in this thread, but you can try at your own risk (in fact, I'd be interested to see if any work!)
Step 10: Click Write.
Step 11: Click the LTE tab. Click Read. Check the bands you want to add, click write. Then, choose LTE BC Config DIV LTE #6829 at the bottom and repeat the process again there.
Step 12: Sometimes the write doesn't go through, and I have no idea why, but I found it helps to play with your phone for five minutes after writing. Also, I found that even if you're not changing bands, it's somehow necessary to flash HSDPA and LTE bands both in one go before restarting the phone. Otherwise strange things happened like losing bands. I was able to get them back though by re-flashing.
Step 13: Reboot your phone and pray.
Step 14: Go into the hidden menu and test the new bands. If they work, you will see SUCCESS when you press them in the test menu. (277634#*#, Field Test, Modem Settings, Network Mode/LTE Band Selection)
I hope this is useful to any other globetrotters!
That's gr8 tip!
Bands are tied to the hardware. Software tweaking won't add them. Not unless they're already part of the hardware, but disabled and hidden by LG for some reason. But that's doubtful.
It might tell you they've been added, but I highly doubt they'll actually work. But I'm no expert so LG may have done something weird here.
So. I have a T MOUS HTC One M8. We have a Qualcomm LTE radio that apparently has access to Band 12 which is TMOUS new 700 MHZ spectrum.
I am currently on band 4 through LTE discovery. Is there any method for adding Band 12 to this version of the HTC One M8.
What aspect of this guide can be used to add to the HTC One M8 T-Mobile Version Band 12?

The added bands do work (depending on the band) so in this phone's case, two new hsdpa bands and one new LTE band were add-able.
I was able to personally confirm HSDPA AWS working on T-Mobile US. The other two added ones I can also confirm because they are scanning on that frequency when using the LTE Band test menu, although there is no local network to attach to.
With other phones even more drastic success stories exist:
http://forum.xda-developers.com/galaxy-s5/general/how-to-add-rf-lte-frequency-bands-to-t2886059
But in this phone's case, the hardware supported more bands than were enabled, so enabling them was possible. I haven't been able to get particularly Band 12 working, probably because of either hardware or radio file, but it was nice to enable some other bands and see them work.
@the_scotsman the hardware in this case is able to do it normally, but LG has to pay a fee to unlock these bands which is why they're normally locked via firmware.

I worked with Qualcomm chips before so the software setting enables the bands in software. the_scotsman is correct in that if there are no antennae on the phone for those bands then the OP's guide will not do anything. Seems that the OP has confirmed that for bands like HSPA Band 4 the antenna is present. It could also be that the LG didn't calibrate performance of the phone on those new bands for this model. That all depends on how they are manufacturing this phone which we will never know.
Anyone else tried this out? I use the Canadian equivalent of T-mobile so I would need HSPA Band 4. I'm wondering if I should buy the international version and get the unlocked bootloader or buy the locked bootloader version for Canada.

I actually want to know the same. I need HSPA B4 (AWS). I want to buy LG G4 H15 version. If I can enable HSPA AWS band, then im on board to get this phone!
Not particularly useful as this requires root

Yes but the H815 from Europe can be rooted easily so this is an option if you bought this model of the G4.

I ended up with the Canadian version in the end. Turns out the H812 has all the canadian bands turned on and once you unlock the device you can go from a carrier who only uses HSPA(AWS) to one that uses LTE without any rooting or enabling bands. Seems at least for the Canadian version all the bands for all Canadian carriers was turned on.

Were you in a confirmed Band 12 area? Or did it say "fail" and not even scan it?
If he had a H811 model, Band 12 is enabled.. I had Band 12 LTE when I was in the US in the Maryland/DC Area..
Sorry for late reply. It said 'fail' and didn't scan. This is European H815. It's now bricked because I played with it too much.
Has anyone tried this on the VS986? It seems that band 2 is locked even though it's listed as a supported band. When using a T-Mobile SIM I only get LTE in band 4 areas and not band 2/12.

On the G3 you were able to use the HiddenMenu via a root-capable shortcut app, but now we can't access it as we get a FC. I skimmed this and didn't see the unlocked BL requirement, my bad!
@duraaraa How do you know if they're "working" exactly?
In the field test menu on my rooted H818P under LTE Band Selection, I have listed 1,2,3,4,5,7,8,12,13,17,20,25,28,29,40, half of which say "FAIL" when you tap on them, including band 28, which is LTE700 in Australia (FDD)...yet this phones' specs indicate this works...so I'm a little baffled?!
I don't have an unlocked bootloader (obviously), so I guess that means I'm no hope of performing anything successful in terms of accessing other bands?

Well, they went from saying "FAIL" when chosen, to trying to find a signal. Not being in a Band 40 country, I can't be sure, of course, but my assumption is, since it became the same as all other bands which were to be supported by the phone, by not saying "FAIL," that it would work.
However, if you are sure that band 28 is working on your phone, and it still says FAIL, this opens the door to having more working than I thought, so it's certainly interesting! Sadly, as I mentioned before, my phone is currently unrecoverably bricked, so I have to wait for some kind of way out of the brick to continue this testing. Ironically, I'm going to China in August so I could have tested band 40

The problem I've discovered is band 28 (700mhz FDD) SHOULD be working on the H818P be default/stock....yet after root and accessing hidden menu, still says "FAIL"
Thats a huge worry, as the LG sticker with IMEI (etc) indicates it should work on that band!
Really hope unlocked bootloader is coming soon for H818P. Confirmed in the DUAL SIM thread, that phone *DOES* support 700Mhz bandwith...but for countries that probably have 100% of their population that DO NOT even own or sell this phone. Band 17 is supported, not Band 28 (densely populated countrieslike Aus, NZ etc). @duraaraa
Really need to unlock band 28!

[GUIDE-WIP] Unlock 3G/LTE bands your LeEco Le Max 2 & fix USA Band selection issue

[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.

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.

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?

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.

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.

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?

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.

Adding LTE Band to MOTO G5 PLUS (XT1686)

I bought Moto G5 Plus (XT1686) from India and now I have moved to USA.
In USA i am using AT&T. Though this device support LTE ( band B1, B3, B5, B7, B40), but LTE doesn't work for this device in AT&T network and I guess it is because of support LTE band incompatibility.
I want to enable new LTE band 17 & 12 on this device (so I can use AT&T LTE band).
I am looking for detail steps which can educate me to enable LTE band 12&17 on this device.
I really appreciate your time and suggestions.

Maybe but that app ain't numbered lol
HI,
I am able to access the "Phone Information" page - but there are no Options to Enable Specific LTE Bands.
Any help is appreciated.
Thanks

Download shortcut master
To my knowledge you can't enable or change LTE bands... Assuming this is like previous Moto devices, that information is locked deep in the device in an encrypted partition and messing with it often gives you IMEI 0 (really bad, no mobile radio at all). We tried this with numerous 3rd and 4th gen devices...
My word of advice is don't try to mod your device in this way, best case it will do nothing and worst case you brick it... Pick up a new or used device if you can't live with HSPA+ (assuming you get that). TBH, depending on where you are, HSPA can be faster than LTE on AT&T's network. lol
Thank you Stokerk - Shortcut Master - does not do much - apart from displaying my current values - again, I am looking to ADD LTE Bands.
acejavelin - Thank you - I may decide to live with this brick / It works on Just 1-band on AT&T - my current Moto G4 Play works on ALL Networks (CDMA + GSM) / Will live with this bad purchase !

Band Selection

Does anyone know how to manually select LTE bands on Essential Phone, with Sprint? My phone is using a very slow band, and I'd like to switch bands.
There's some sort of menu which comes up if I input *#*#data#*#* in the dialer, but I don't know what to do with it.
Edit: worked it out. I needed to enter 000000 as the msl

Essential Phone Service Menu

On my old Samsung phone I could enter service menu and switch bands. I have tried to enter service menu on the Essential using *+#000000#, but I get "Connection problem or invalid MMI code". What am I missing?
Does anyone know how to switch bands on this phone, and make it stick? I'm tired of being assigned a crappy band with low signal at inappropriate times.

Yes, I have done that one. It is not the true service menu, but the test screen, where you can choose between CDMA, LTE, UMTS, etc. but that's not quite what I'm looking for. It won't stop the phone switching to a low performing frequency channel. I want to be able to switch to say band 4 or 5 or 66 and have the switch stick, disabling band 17 and 2. But thanks for the reply. The original *+#000000#, is close, but I'm missing something. Still looking.
