Many of you are probably aware of the Testing menu containing network and other various settings (you type in *#*#4636#*#* into your dialer).
For years I've used it to mitigate the spotty 3G connection in my house, to keep the phone from 'flickering' between 3G for basically every other room in my house.
Using GSM auto (PRL) keeps me on GSM indoors and switches to 3G as soon as I leave the house. This also has a noticeable improvement on battery life.
Only now it does not persist through reboots. It always defaults back to the original setting, which even includes TD-SCDMA which is a Chinese-only network type that I never want my phone to scan for at all.
So far the only thing I've been able to do that persists through reboots is
Code:
su
settings put global preferred_network_mode 1,20
This will force it to GSM only. Only 2 other codes persist: 18,20 which is another TD-SCDMA inclusive and 20,20 which is the default.
These correlate to the Preferred network type in SIM card settings.
If anyone has any more insight into this, I'm pretty much out of ideas.
EDIT: I realize now that the issue might not be exactly made clear. It's a very specific set of circumstances:
The testing menu (*#*#4636#*#*) applies changes to the network immediately, but not persistently.
Editing the values does not apply changes immediately, and only persists on those 3 values after reboot.
you can use intelli3G, but it requires xposed installed
Thanks, I'll keep it in mind as a last ditch effort.
I'd rather not run so many auxiliary programs, especially when the required function is so minimal, but the program so extensive.

oops, I tried Intelli3G, it does not work well, caused overheat.
maybe you should try smart network, it is more compact, but I am not so sure

You can use an init.d script to set the network mode at reboot

Sorry, I should have phrased that more clearly. Apart from the 3 that were mentioned, no other values seem to affect the connection. My ideal solution would indeed be an init.d script.

Maybe we're looking at the wrong entry, if i change the type from the menu I always get 18,20 from setting though the network seems to be changed...

Yes, that's the issue exactly. From the menu the changes are applied immediately yet the changes don't stick. From editing the values the network remains unchanged until reboot, but only those 3 values will stick.
I wouldn't know what setting the menu would call upon other than preferred_network_mode
but I don't know much tbh, that's why I hope someone does

Right? I can't find anything on this. There must be a mirrored table somewhere where the value is held. Or maybe the setting stays active in a system app that is kept in memory? Like phone.apk or something.
I might be saying ridiculous things, I'm grasping at straws here.

Yup, specifically those are ignored. I had tried them previously and thought maybe build.prop changes were ignored entirely (I hadn't made any tweaks or anything yet), but other changes to build.prop work just fine.
Could they have hardcoded these into the radio perhaps? I guess not since it can be affected through the testing menu... I keep going back and forth between theories like this, can't make sense of it.

I start thinking the RIL change the values after build.prop load... Maybe they coded a method that initialize the daemon and only accept the 3 option reachable from settings...

Any news on this? Been having the same issue on miui9 redmi3!

On my Evo, I have tried a number of different things to conserve battery. One of the issues that someone suggested related to a possible bug in the way that the phone interacted with the Sprint network- it apparently continued to search for CDMA even if connected to Sprint CDMA (please forgive my lack of specificity about this- I have absolutely no understanding of how CDMA networks operate).
Anyway, on the Evo boards, an app was recommended that allowed the user to specify the type of networks that a phone would use- called (appropriately enough) "Network". It's hard to find in the market; I think you have to search by the dev name- which is "mangelow". I used the app to set "CDMA only" instead of "CDMA PRL", which supposedly addressed the problem; by my own rough estimation, battery life improved (although slightly).
The app downloaded to my TB when I first logged into the market, so I thought I'd give it a try. It shows different options since it's on Verizon (which makes sense), the default being "CDMA+LTE/EVDO Auto"; there's also a "CDMA only" mode. I selected "CDMA only" in a known LTE location (my office) about 2 hours ago; yesterday at the office the phone was in LTE mode all day, as it was this morning before I switched modes, but since switching, it's stayed in 3G mode constantly.
I'll leave it to the smarter types to confirm my hypothesis, but I thought I'd toss it out there because it seems to work so far. There's not a widget or anything for this- you have to use the app to make the adjustments each time you want to change, but it's at least more than we have currently.
I suppose a disclaimer is appropriate, since I'm recommending someone else's app- I have nothing to do with the development of the app, and it wasn't my idea. If this works, any credit should go to the developer, not me.

I know this has been talked about already, but are there any widgets that can do this quick swap for you? My wife's TB arrives today and I want to disable 4G for her (but have it EASY for her to turn it back on if wanted/needed with a simple press of ONE button via a widget). I disable my 3G on my AT&T Captivate, but do it through the settings menu with several different button presses to get it done. This saves a HUGE amount of my battery on my Cappy and I imagine that it will on the TB too.

Is anyone else having trouble getting the phone to switch back to 4G? Sometimes it switches right away for me and others it won't. I make sure the CDMA + LTE option is checked but nothing happens and if I reboot my sometimes it will be back on 4G and others it will have switched back to CDMA auto and then I have to try toggling the switch and rebooting again.
So I've been trying to tweak my signal, go into dialer *#*#4636#*#*. Go all the way down, under preferred network type says unknown. Click on box and options are, wcdma preferred, GSM only, wcdma only, GSM auto prl, wcdma auto prl, GSM/wcdma auto prl , evdo only and i think 2 more. One of wich is unknown. Phone is rooted, stock rom. Any ideas? Live in Colorado

yea i was wondering the same thing. my evo is/was always on CDMA auto PRL, my ns4g is either on WCDMA or unknown. i cant help but think this has a lot to do with reception issues
Edit: Also switched cdma roaming to home only not automatic, not sure if auto made it keep switching to unknown type. Waited a cuple minutes after turning 4G off and speed went back up, might have needed a minute to fully switch back to 3G. Been messing with preferred type, but to make it stay have to push home cause back button keeps resetting to unknown type. Check speedtest.net app, shows better speed, but when i use the 4G and then turn off speeds are worse again. But then again you'd think cause i get a low 4G that my 3G would be faster, not so.

add the italic underlined code, without being in italic and underlined. and replace the x's with whatever you want to use:
GSM/CDMA auto (PRL)
EvDo only
CDMA only
CDMA auto (PRL)
GSM auto (PRL)
WCDMA only
GSM only
WCDMA preferred

Gothis from Build.prop thread-use *#*#4636#*#* to access network type, wait for signal to turn green, select network type then quickly go down to refresh and then update. These are next to the smsc box. So far it seems to be sticking, not sure about after reboot.

These were my steps
1. Go t system and make a few copies of build.prop.
2.went into copies of build.prop, ( main build .prop runs in background so it would let me alter).then added witch ever type i wanted , (like me i did ro.product.rat=WCDMA preferred) .
3. Made sure i saved my new copy.
4. Then i copied and pasted my new building.prop over to system. (Says there is already one there, i overwrite original.
5. Get out of whichever explorer used. And restart phone.
6. Then went to *#*#4636#*#* to get to preferred network type, then i select the option i chose to put in build.prop. ( that way they are the same.
6. After selecting type quickly got to refresh and update ( near the smsc box near the bottom.
You should notice the update tab stay dark.
Before i messed with build.prop and added what i wanted it would still change back. Now it atleast stays till next reboot.
Don't know if that helps.....

Didnt work. Switches back to WCDMA upon leaving the menu. Then shifts to unknown.
This phones radios need some serious updating...as well as some other problems.
Is yer rom odexed or deodexed, is it stock rom or different. I read somewhere that a deodexed rom allows a little more play as far as changing things, not sure though. It stays as long as you don't reboot after refresh and update, before it would reset regardless of reboot or not. Did you check build.prop in system folder to make sure it kept the add in? Mine wouldn't stay untill i copy and pasted over the original in system file, cause build.prop runs in the background. But there are so many things that work and won't work depending on yer rom and how it runs.

stock rom. performed multiple variations of the steps that are assumed to work. nothing works as it always switches back to wcdma then unknown.
I have found that I make the wcdma change with *#*#4636#*#* the change shows. If i make shortcut in home screen for phone info the line still shoes gsm/cdma. I still have to change it there.
I recently tried to fix my GPS issues by trying out some previous OPO modem files, I ended up just reflashing the 33R one though as none helped. I now have a more annoying issue since doing this.
My network, Three UK uses LTE/WCDMA, so in the *#*#4636#*#* menu it is best to set "Set preferred network type:" to LTE/WCDMA, but after a reboot this changes to GSM every time, resulting in no signal at all.
I did some googling and found that some people had been able to edit their build.prop to change this default value, I changed the values as seen in the attached image. Unfortunately after a reboot it now only changes to WCDMA only and not LTE/WCDMA only. Does anyone know what changes I would have to make to make it change to LTE/WCDMA only?
Thanks.
If someone could upload their default build.prop that would also be useful.

Three has no 2G network at all, 3G/H+/LTE only. With it set to "GSM only" I have no signal at all.
I just need to set it to WCDMA/LTE and it works perfectly. The default config (after a reboot) that came with the phone works great too but it's changed to GSM only after flashing modems.
I've just flashed stock system.img, boot.img and modem using fastboot from the 33R fastboot zip but it's still not working as I'd like.

I don't think you need to. Just go to phone, press *#*#4636#*#*, press phone info and tell me whats in Set preferred network type, if it's what I think it is, upload your build.prop and I'll be very happy

That's a testing area, you shouldn't use it for setting parameters.
Anyway, try to go to setting --> mobile network setting and set the preferred network type there.

I know that, but after rebooting the settings change to GSM only. I wanted to see what his was set to to see if his build.prop would be good for this. Build.prop seems to override that setting,

I had the same problem, after you change 4 or 5 times it finally is fixed
If I am correct, the OnePlus One is not CDMA compatible. If I am wrong on this, please correct me and I'll go pick one up for Verizon right now...

Sorry but no you are correct. If it worked for Verizon, then my life would be easier
this works but requires root, it works for dual sim as well, the settings will "stick" (save and apply) after a reboot. and PLEASE NOTE that of course you change the "3" to your preferred network
https://forum.xda-developers.com/galaxy-s4-sprint/general/how-to-fix-network-signal-gsm-sim-t3720534
decided to take a risk and add a line to my build.prop about preferred network..... but it didnt work!! I told it to use WCDMA only and it is STILL switching over to HDSPA... i get better reception when i go into the phone info menu and switch it to WCDMA , but it will not stick..... i thought adding a build prop line would finally do the trick, but its still auto switching!!
help?
What phone is it, stock or custom rom, and have you verified that the file is edited correctly, and still modified when you reboot?
Samsung captivate glide.... No im not sure if its in there correctly as i had asked which line im supposed to input it either above or below, nobody got back to me. So i downloaded and used a build.prop editor, and put the name and value in there, thinking it would put it in the proper line/place. But, it did just add it to the bottom. Thats what i would have done as well, but i wasnt sure.
It is a stock but rooted ROM.
the information is in fact still there after reboot.... but it still reverts back to the other weaker signal, with phone info saying GSM/CDMA auto PRL which has been its default this whole time... when i want it to say WCDMA only....
Doesn't the Settings - More Networks option allow you to set the Preferred Network?
It might, if i had that setting to begin with... Mine doesnt.
I can choose which operator i want to use, but thats as far as it goes. but im wanting to use a different network under the *same* operator...
Would adding that line to "default.prop" help with this at all??
Hi, i just want to know if there's any option to change network type to 3G ONLY (or 2G only). The options in settings are preferred network so they switch to another network type when needed, and I dont like that.
I tried *#*#4636#*#* and change it from there but it still goes back to original setting.
Any tricks/solution out there? Thanks!!!
I used to use this http://forum.xda-developers.com/android/apps-games/widget-toggle-network-type-5-0-xda-t2945406 but it's not working for me after installing CM14.1. Some people say it's working in their devices with Android 7 though, so give it a try and see. Needs root.
If it doesn't work and you ever find an alternative, please do let us know here.

Hi, I think I found a solution. I still use the *#*#4636#*#* code and choose WCDMA Only and leave it as it is. I noticed that it only goes back to original network type IF I enter the "Cellular network settings" screen (**even without changing any options in it). So just stay away on that part in Settings and your network will stay as you selected.

Yeah, I was aware of that. That behavior (reverting to the selected mode in settings upon opening the activity) was introduced in Marshmallow. Who knows why. Unfortunately this is still not ideal for me because I usually keep the phone in 2G only unless I need a faster connection. With that plugin, which no longer works, I could use Tasker to change network modes depending on contexts or a simple tap in Tasker's persistent notification buttons, which I had configured to do just that. Going into the dialer, entering the code and then navigating through the option every time I need to change modes is too much work, but I guess I have no other option until either the dev updates his plugin or another plugin is developed.
Thanks anyway, mate.
