I have G710EAW (LG G7+) which has by default active LTE Bands 1,3,5,7,8,28. However I live in Europe and I with my carrier I would benefit from band 20 as well.
What I am doing currently, is via service menu I am activating manually all the bands I need (including band 20) in modem settings. This works perfectly fine, actually I am so used to it I can do it within seconds. Naturally after phone restart all is reverted.
It is a minor inconvenience, hence the question: any idea how to make the setting persistent or any tool that would do it after each reboot?
I would like to avoid installing firmware from other model (if that's even possible, I am layman in this...)

I don't know if Tasker needs root but you may be able to accomplish it with Tasker.
Although it may be a pain to setup i think tasker has a subreddit that you may be able to ask somebody who uses it more than I do

Hi, I'm also looking to buy the EAW version for the dual sim feature. So you confirm the phone has all the LTE bands but some of them are locked by the software installed?
I need a phone dual sim that works in Europe and USA....

Well I do believe Qualcomm Snapdragon is an excellent platform and the build-in modem is capable of all bands. I do have EAW version (I think originally from Hong Kong).
The band selection is not available from OS, but if you dial *#546368#*710# there is a hidden menu where in
Field Test -> Modem Settings -> LTE Band Selection I have these bands available:
1,2,3,4,5,7,8,12,13,17,20,25,28,29,30,38,40
To my limited experience any combination works just fine (I am in central EU). The drawback is that after reboot (or airplane mode) only the default (1,3,5,7,8,28) are on.
Just for the hell of it. I tried on my US phone, can't even access the menu Sucks.

It works for me on the T-Mobile variant you have to use the stock lg dialer and type the code in you cant just copy it in
How do you know this has worked? I toggled on the bands that I need bu there was no 'success' or save prompt and if I exit and re-do the process all the boxes are un-ticked when I navigate to the LTE bands page.

Sorry for late reply.. I'm using stock dialer, and enter in manually, still doesn't work.. Maybe it is a T-mobile code or something.. I'm not use to having a phone were I can't access the hidden menues..

Weird it takes me right to the menu once I hit the # sign on the end
I get the menu ok just no indication it has worked and the setting has stuck.
I have the 64GB Global version
Last Miui 10.3.4.0
I live in Argentina, we use this four LTE bands: 2 - 4 - 7 - 28
The phone can connect ok to those four bands individually but I think don’t is not doing CA, not even 2CA
My previous phone Samsung A5 2016 did 2CA ok, I don't remember exactly all the combinations, but I think 7+28 and 4+28 for sure
First of all, how to see if Mi9SE is doing CA without root? I use *#*#4636#*#* and Cellular-Z app
The phone claims to support 3CA; but which are the available combinations?
Tested also the app "NetMonster"; there its shows up to 4CA which I think is fake, so I discard this app.
Thank you in advance!
Yes this device support 3CA, here is supported combinations: https://cacombos.com/device?model=M1903F2G
Yes Netmonster doesn't show correctly. There is app called Network Signal Guru what show real data but require root.
Hello.
AT&T has disabled all the international GSM\LTE bands on Z999, making it unusable outside of USA (at least in countries with GSM 900\1800, UMTS 2100 & LTE B3 & B20, like the one I live in). In order to change that, we need to turn on the Qualcomm USB Diag port, and for this, the phone has to be rooted.
I've been trying to root my AT&T Z999 for some time now, without any success, unfortunately. However, searching forums after forums, sites after sites, I've discovered the surprisingly easy method of turning on the Diag port without root.
It appears, that Axon M shares a lot with Axon 7, at least the secret key combination to enter Factory Test Mode:
Turn off the phone
Press and hold Power + Vol DOWN buttons until you see the screen "FTM" (see attached screenshot)
You have to press both buttons for the long time, do not release them when the phone starts - just wait until you see the screen. And that's it - you are now in Factory Test Mode and PC sees your phone as "ZTE Handset Diagnostic Interface (COMxx)"
Now, in order to change the bands, you have to follow these guides one after one:
Backup IMEI and NVRAM (ignore all the steps to turn Diag port on, you've done that already)
Unlock LTE bands
Mod edit: Link removed! (this guide in in Russian, but all screenshots are in English & every step is pretty clear)
You would need this tool also.
Please remember, these things are complex, and require considerable experience with Android & Windows. DO NOT START unless you feel confident that you know, what you're doing. I'm serious. Do not try this, if you're not experienced.
WBR,
Draco.
Why mods deleted the link? Google translate exists.
Edit:
I've managed to get the data from the phone using QXDM.
lte_bc_config contained the value of "2251800618993690" now I'm parsing the info how to edit this. Seems like the tutorials don't really match this device. Now I wonder if the chipset can handle invalid data and just input all 1's. Unsupported frequencies just won't work.
Edit2: Writing all 1's didn't work.
Edit3: I wrote this value: "2251802901219551" Calculated with CDMATool. But it seems like the AT&T firmware only finds edge network. I've double checked the bands to be correct ones. So now I will switch to the chinese firmware.
Edit4: Final edit. Turns out you cannot flash chinese firmware on AT&T device. Sigh so my unit is stuck to EDGE/wifi only.

I can't "repost" the 3rd link, but I can suggest you to open the well-known (and the best) Russian web-site with the name starting with "4" (and having something like "...pda" also), and then add this to the address: /forum/index.php?showtopic=546814&st=4640#entry35702698
Well that russian site has pretty good instructions on how to do it. I tried with one program and it didn't work on AT&T ZTE. I'll try with that qualcomm app again this weekend but if I remember right the last time it had trouble writing because it had no correct service mode code \o/

Every Quallcomm device has almost the same NVram configuration rules, the difference is usually on how to enable diagnostic port, but for Z999 I have figured that out already. So, for the configuration process, every Quallcomm guide should work.
I've successfully enabled Z999 to work with 2G & Edge in my country using these guides. 3G & LTE don't work yet, but I'm sure they will eventually. I don't believe Z999 lacks the hardware ability to use LTE B3 & B20 (and other bands), it has to be something wrong with NVram parameters.
For me 2G and Edge worked out of the box in Finland. Tried to enable more but only thing that changed was power usage. Not worth it

It means success unlock 2G/EDGE, not yet with 3G and LTE? When buy the device, it can use other carrer to call and 2G.
When you finger out the way to unlock LTE, please share me.
by the way, do you have the way to enter fastboot mode? I tried the "volunm + &power button" but it just do a normal restart into android.
Fair warning to everyone trying this, make sure you actually do a backup of your IMEI. I didn't and after screwing something up my SIM is no longer detected, and my IMEI is no longer available.
Hello folks!
I have an AT&T phone. I cannot connect to ANY (even EDGE) network!
I modified the configuration several times:

01877: 562949974393728
Only edge network, error while searching for networks.
----
06828: 524485
06829: 524485
I have EDGE with this config, but no LTE.

Anyone has a good and working LTE mode?!
edit: "The bands on the AT&T z999 are: 2, 4, 5, 12, 29, 30, and 66. "
So, there won't be any Band 1,3,20 for us?!
Thanks!
No one has gotten LTE work on AT&T model. I wouldn't try this.

Have you been able to make 3G & LTE work? I just got my ZTE AXON M from ebay and since I can't use data or make calls/unlock the phone I was thinking of trying this.

Can I describe in detail how to enable 2G?
Thanks !
Hello guys. I've tried all configs mentioned by @ugynok and some of my own - the result is still the same, no 2G network and all options in mobile connections are disabled not clickable. Can you please advice which config worked for you to enable 2G network?
Any luck?
Hi all. Was anyone able to get a useful set of bands working in the UK for this phone?
Many thanks.

It's the mistake. I don't know how to delete it, sorry.
Does Moto G8 support carrier aggregation? LTE-A? Can anyone confirm or deny this? I have seen conflicting information. What LTE category does this device support? Only Cat 4?
There is only way check via modem log but Motorola doesn't provide any non-root method. If you have rooted device, you can take log with Qualcomm diag method https://cacombos.com/contribute
Thanks for the answer, unfortunately my phone is not root. For now I have no plans to change this (for warranty).
I asked because I saw conflicting information. Some reviews say that we have LTE Cat 13/5 (400Mbps / 75Mbps (Notebookcheck), others talk about cat 12 (600Mbps / 100Mbps), and on the Motorola forum I only found information about cat 4.
Tried checking with NetMonster and sometimes saw aggregations of the two bands (2600 + 800Mhz for example) but the program only showed LTE and not LTE-A. And aggregation disappeared when data was turned on (maybe it's my carrier fault?). I've never seen an LTE+ icon. I also know that this application can show nonsense.
That's why I wanted to ask, because maybe he has already checked it?
Then i don't know any other way to verify Carrier Aggregation support from your device. Not every device show 4G+/LTE+ icon - some maybe show fake icons also.
CAT13 is 2 Carrier Aggregation with 256QAM (Theory up to 400Mbps)
CAT12 is 3 Carrier Aggregation with 256QAM (Theory up to 600Mbps)
NetMonster is not reliable way - I think best way is via modem log. There is instructions https://cacombos.com/contribute but for Motorola there is no non-root method to verify.
--
There could have also multiple different models so please share your device model number. It's in Settings -> About so then if someone else share more details or log then it's important verify device have same model number.
Thanks for the answer. Yes, I know Netmonster can be wrong. In that case, I am waiting for the answer of someone who checked the method described by you. My model is XT2045-2.
Hello! So I got the Pixel 6 Pro and I am coming from Galaxy S20U (Owned Pixel 1/2/3/5)
So on my S20 I can change NR/LTE bands as much as I like without root by using an app or the hidden menu *#2236#
Where I work all day its all concrete walls, so me locking LTE Bands its a must.
I can not do that on my google Pixel 6 PRO and yes I tried *#4636# but those options do not work with me because you can not lock bands.
I am ok If I need to root my 6Pro in order to do this, Will Network Guru do this once rooted? I am willing to include reward $ for whoever helps me with this.
Thank You
I'm sad to say that Network Guru simply won't work because Pixel 6, Pixel 6 Pro uses Shannon Modem for 5G, which is an Exynos modem (if i'm not wrong) and Network Signal Guru requires Qualcomm Modem to work.
**edit: typo**
Under settings__internet__gear wheel next to your carrier and scroll done to preferred network type. Unless you don't have that option.
I'm still trying to figure out diag modes for this phone. I can get the modem and serial devices to show up. Per my conversations with cstark:
resetprop ro.bootmode usbradio
resetprop ro.build.type userdebug
setprop sys.usb.config acm,dm,adb
setprop persist.vendor.usb.usbradio.config dm
Revert:

Everything seems to be controlled by /vendor/bin/modem_logging_control and /vendor/bin/dmd.
Regular START/STOP calls to modem_logging_config from root shell can yield usable logs. We can also get the apps started in special SHANNON_DM or SHANNON_APP modes, but no idea what to do with them.
For example:
modem_logging_control START
modem_logging_control SHANNON_APP
modem_logging_control STOP

Logs saved to /data/vendor/slog/.
The Shannon DM version floating around is too old and I haven't gotten a decent scat setup. Airscreen might work but Network Signal Guru doesn't. No tools for this phone are good at the moment.
And that's the extent of our knowledge at the moment...

Thank you, I will try to be checking on this if decide not to return the phone. Is Airscreen a Magisk Module?
No, it's a desktop app. There is no band locking.
Can someone tell me the benefits of this mod? Genuinely interested.
Lower frequencies penetrate walls and concrete better than higher frequencies in the spectrum, at the cost of speed.
Locking a 5G/LTE band helps save battery life because it prevents constant hunting for a better signal between bands.
You can try your luck with 'Shortcut Master' app on Google Play. Once opened click on show all apps -> Phone services -> scroll until the bottom and click on band or radioinfo and click on Launch. Then you can change the band and frequency as per your liking.
No wifi at work?
A lot of workplaces have strict firewalls and network policies in place so it's understandable to use your own network connection for non-corporate usage

With this method let's say I choose class 9, it will remain locked?
I believe this is a WCDMA band selection and will have no effect on LTE/5G, am I wrong?

I think you can simply turn off 5G from the settings menu. (You can also set Prefferd Network type to LTEOnly from Radio info... *#*#4636*#*#)
The sad thing is that you can't fix the band in Network Signal Guru (or any other APP).
This may be difficult to do unless Google provides a development tool that supports Shannon modems.
The above looks like something different, aiming more at 'by region or country' to me. Not the traditional band selection found in other devices. It'd be nice to find out if we can systematically program these to hunt on certain LTE/5G bands. I am on a tmobile migrated sprint plan on my p6p. It works great except for that fact that where I live band 26 is garbage. The only solution realy is to find that sweet spot when it swaps to 25 or lock it into the device. So would be nice if the google momos release it, you know, in the spirit of open source, like they initially set out to do so many years ago when android started.
good news everyone. version 4.0.4 of Network Signal Guru has band locking for the pixel 6
