[Android] Disabling 3G For Kaiser for NAND rom -- please help!

As some devs are aware there are those of us who need 3G disabled on Android for our devices. Using the option to "Only Use 2G Networks" does not resolve this. (edit: also, neither does the *#*#INFO#*#*)
I thought it might be helpful to create a thread about it so that if anyone comes up with a solution or if a particular rom build can address this issue (I'm not an expert but it seems like it will have to be a rom based fix? which is why this isn't in software development) there's a place for it.
I use AT&T and have validated my APN settings and tried all manner of selecting the "use only 2g" option (restarting, manually selecting networks, automatically selecting networks, etc.) but it always goes back to 3G.
This can be disabled as if I disable 3G through WinMO it works and HaRET seems to behave when I use it that way (I still select 2g only though).
Personally I use HardSPL 3.56 and Radio 1.71.09.01.
Please help us out Perhaps we could start a bounty -- I'd like to start with $10 for a validated fix.
If someone would be willing to walk me through a build process for their rom perhaps I can test/fumble through C myself and create a "patch" or something that can be applied to other builds. Please feel free to PM me if you can do that and I'll keep any information on this thread.
Thanks for reading this and any help you can provide or direction you can point me in! This is a great community!

---------------- UPDATES -----------------
As reported by Softec 2G/3G switching is working for Polaris (Pola100) using KaiserDroid 2.0
http://www.homecncfun.com/kaiserdroid/
Thank you slm4996!
I am trying to use KaiserDroid 2.0 on my Kaiser (Kais160) but thus far haven't gotten data to work. Stay tuned.

Hi
Thanks for starting this thread I am using the same phone (kaiser 130) same hard spl 3.34 and same radio.
I too live in an area where I need to disable 3g to have a usable phone, and have found the same - disable in Windows Mobile and load via haret and then android never tries 3g.
I like the idea of the reward, I'll match your $10 so that makes a $20 bounty on this one, I can test for anyone if they're trying to fix it.

There's a few different ways to accomplish this. All do the same thing but some may be easier for you to do based on your experience. I don't know if the ROMs need to be rooted but given that these are ports you should have no issues with that. You can search through my posts, the various threads or PM me if you need help with that.
Basically you are going to corrupt the (going off of memory here) /etc/apn-config.xml file to point to nonexistent APNs. You don't need to do both of these, these are just different ways to do this:
1.) Download Droidsans Tweaks Lite from Market (free) and you can use it to disable the APN, or you can just to to the APN settings and change the APN name
2.) Download APNdroid (free) and toggle connectivity
There's other ways, but giving you two options should be enough. If you are good enough at messing with ROMs, you can always just delete the apn-config.xml (or whatever it's called) in /etc (which is in the rootfs.img) and it will never connect.

I don't think these 2 actually turn off 3g just the data, my problem is the 3g signal is too weak to be reliable so I need to force 2g completely, not just disable the apn

then can't you just get one of the various (curvefish for example) widgets to toggle 2G/3G or go to settings and say 2G only?

Currently only via Haret

Well the only thing I can suggest is via haret.
1. Via windows goto com manager and disable 3g, and confirm that you have edge showing and connected.
2. Boot haret and you will be limited to edge.
short and sweet.....
the speed is decent enough for me to consider a nexus or desire on ATT's 850 mhz HSDPA/4g

ps. I hope your thread pushes for a solution via nand b/c its important.

Sorry n the dsiabling 3g when runing android does not work on the kaiser from our experience, the widget is just a shortcut to the menu.
As noted in post 7 and I tught above the only soluton is to run via haret and. Disable it in windows mobile to re-enable reboot the phone and enable in windows then run haret again.
Can we change the thread to - Android via Nand on Kaiser Disable 3g solution required or something clearer
I would love to be able to run via nand

I have this problem too, i can't disable the 3G signal, i think this problem is only in Kaiser.
i like if someone can "fix" this for us.

Thank you guys for the suggestions. HaRET does work if the WinMO ROM hosting can disable 3G (which most have a switch or something).
I have googled for some time searching for a toggle/switch that disables 3G but as mentioned have only found ones that point to the menu rather than actually disable 3G.
As mentioned the menu does not work.
There's a $20 combined bounty on this already! Please help us out!!

Newest KaiserDroid
I am using a new RIL in KaiserDroid 2.0, have you tried it yet?
http://www.homecncfun.com/kaiserdroid/
If it works I can backport it to older roms till this one is more complete. Thank you for all you feedback on the KaiserDroid thread.

I'll give it a try and let you know...

You're welcome. Do you want to keep using 2.0 or should I backport it for you?

Thus far with KaiserDroid 2.0 I haven't been able to get any data to work. I didn't test making/receiving phonecalls. I plan on posting thoroughly soon but I want to play with it some more (perhaps I've done something ignorant, haha )
I've been using HaRET to test and left my MicroSD at home today will have to try more later this evening. I will also check out KaiserDroid 1.1.

Try this update package, it fixes some of the APN's and adds a few more:

Hello, it would be nice to have the opportunity to try different rom, can you tell us what to do if you would be very grateful.
For your rom I noticed that it is a bit slow, the data in WiFi will not work and above all the bateria takes very little.
Charged 100% no WiFi and only a few calls, it was switched off after 6 hours.
I tried the version 2.0, now I have downloaded version 2.1. Test and let you know.
Thank you very much.

Please read the thread for the rom you use!! These are all known issues with all ROMs flashed to NAND and to some extent under HaRET. the appropriate fixes and/or workaround have been posted in the thread. I am working a howto to back port the RIL but if you start poking around in the sysinit.rc it should be fairly obvious what files you need.
keep in mind that KaiserDroid 2.0/2.1 are ALPHA release and as such contain bugs.

Hello slm4996, it was not my intension held high controversy, I just wanted to clear up why do not I was using your rom and use the 3G off on another rom.
I looked at the file sysinit.rc as you recommended and I changed the line:
service ril-daemon /system/bin/rild -l /system/lib/libhtcgeneric-ril.so -- -d /dev/smd0
with
service ril-daemon /system/bin/rild
Then I replaced the file /system/bin/Rild from your new rom and it worked perfectly.
I can make and receive calls on 2G without problem. I have not tried the APN but I'll try to short
thank you very much.

Data connection after unlock ATT

In your cellular settings you will have to add the apn data to get the data going.
Can't help much more without knowing your provider.
Helps to download the Nokia Connections app.

If you are using it on other carriers, you will need to configure the APN. There are two ways to do it;
1. You can maunally add the APN of your carrier to the phone but you will not get MMS working.
2. You need an app called Network Setup from Nokia to switch the connections to your carrier if it is in the list. This will switch both data connection and MMS.

//Side-note// That little green thing is supposed to be an android? How? It looks more like a little green trash can or MAYBE an alien...
android (plural androids) + Noun
A robot that is designed to look and act like a human (usually male)
That thing looks like a human? Google has NO reason that they weren't able to do a search to make sure they knew what the word android meant... I mean, I guess it's a bit ironic... But that little green trash can is NOT an android.

Dont get me wrong, i like android, it has some features that complement me much better, i just wanted a phone that works and the lumia 900 works and looks great. My old lg optimus 2x just had crap for support and the OS that LG created was very buggy. Maybe someday i'll return to android but i wanted something that is smoother. so far so good.

Oh, to be clear, I like Android too... I was just pointing out that the little green thing isn't really an android by definition... I may have been inebriated at the time I posted that ;\

no data after flash to cricket

Hi first off let me start out by saying I am a big newb to this kind of thing the most I have ever done is root a couple of phones and installed a couple of roms a long time ago. I didn't intend on buying my opt g but I was on Craigslist and saw it at a steal of a price so I picked it up. The phone was already previously flashed to cricket (that's what I have) it was on the sprint network before. I activated it when I got home but my data does not work I read up on line and by the looks of it I think there is a fix for this I haven't tested Mms but I will put my money on saying it doesn't work either. Can someone help me get pointed in the right direction to where I can find a tutorial or guide on how to get my data working. I found some stuff but it's for other phones and I didn't really understand the directions and the stuff I found was from 2010 so I'm thinking that's old info. In advance thank you everyone also I don't know if it matters or not but on my cricket plan I have 3g so that's what I am trying to get to work on phone

I think you just need to change the APN's.
Go to Settings->More...->Mobile Networks->Access Point Names and select the relevant APN if it is there.
If not, you'll need to find the details for your provider (Google "Cricket APN") and add them to the device (don't forget to save).

I have updated to zve... my phone is still unlocked! :good:

Phone remains unlocked. Unfortunately, it wipes APN data and now I can't go in and edit APN. Anybody have any work arounds? I can't add an APN (no option) in the settings menu (settings - more - mobile networks - access point names) nor in the ##3282# menu with the MSL. It's been a huge pain and I'm currently trying to use this phone in Peru. It can make and receive calls/texts but will not access the internet without being able to add/edit APN's.

But if anyone knows how to do it please i beg you i need help as it was my gift to my father and i fu..ed it up :crying:

Why,LG, why?
Gah this is so frustrating. I had my phone unlocked by sprint and am currently abroad, but had the wonderful combination of ideas to both update to ZVE and reset network settings. I've already been using this international sim for five months and everything was fine and dandy, but now I can't add an APN so I can't connect to the internet (the apn settings are greyed out) - I even spoke to Sprint for 3 hours and they concluded there's nothing they can do. I'm thinking there's one of three things to be done: change the APN by some "hack" like a dialer code or ADB, revert to previous firmware, or connect to the internet somehow without an APN.
Does anyone know how to do either of three things? Please help.
Update: I called LG and Sprint for a combined total of about 5 hours. LG confirmed that indeed with ZVE they disabled manual changing of APNs (due to "security") and they don't even have a special code or anything to fix that. They said I should ask Sprint to maybe push an ota apn for the international carrier but they said they can't do that. The LG guy said that he would add a ticket (they can't even talk to anyone higher up) to tell the dev team to add an option again to change APNs but I don't know how likely that'll be. It's just super frustrating that LG pushed an update to break international data and now says they can't do anything about it. Reminds me of my bootlooped Nexus 5x that they said they couldn't do anything about. Smh lg, smh.

Welcome to my hell. I tried to warn the community in my comment about this exact issue. I spent weeks talking to Sprint and LG's useless "technical support." LG reps kept insisting that LG has nothing to do with software updates which is completely wrong and extremely ignorant of them to think that. Sprint advanced tech support even conferenced LG in on a call once that lasted about 45 minutes and the LG rep kept saying they don't have anything to do with the updates. Finally, we got him to agree that they did make the updates. But, even that was a waste of time. It wasn't until I wrote to LG through their website that I got several responses (mostly the same as before - walking you through how to change APN settings) but, finally in those conversations, I was able to get LG support to admit that they had a problem with ZVE and that they are the ones that broke it. The last response I got was that their developers are aware of the problem and are working to fix it. It probably won't be fixed until the next software update and they won't give me any timeline as to when that will be. It's been a couple of weeks since I last talked to LG. My advice is to do the same and file a bug error on their website. Calling in is a complete waste of time. They need more reports on this so that they know this is a big issue. You can't even go in with your MSL and change APN's. If they were really worried about security, they would at least allow the carriers to give you permission to modify the APN. Seems completely nonsensical to me.

Never update if you have an unlock. I've said this a hundred times... Maybe you can get on eBay and get a remote unlock.

How does one file a bug report? I looked and couldn't find it.
As to the reason I updated my phone, I'm very involved in security and need the newest security patches I can get. Also, I don't know/don't think a remote unlock will help, I think it is actually fully impossible to add an APN at this point... I even had sprint lock and unlock my phone...

Sometimes you can't have your cake and eat it too. A bug report will get you nowhere. I've filed legitimate bug reports with solutions and didn't even get a reply. They did this on purpose and don't care if it effects you. They don't want you to use your device the way you want, they want you to use it the way they want.

I read this in other post
Idk this work

Google, download and install HiddenMenuCall_1.7.apk
Go to LTE Settings
Go to APN Settings
Set APN there and use "default,dun,fota" as APN Type
Restart phone
Done!

Pixel XL on Verizon MVNO - April Security patch has disabled my 4G.

I had 4G before this update, but nothing I do, no matter how many different APN settings I try, no dice.
I'll tell you where I've been. Have had the phone at least a year and it came with Nougat.
As soon as I got it, I got a Total Wireless SIM (owned by Tracfone and running on Verizon's network) and activated it with no problems. Had full service. 4g, mms, etc. All was great.
Even when I got the 8.0 notification and I updated to Oreo, all worked fine.
A few months back, I got the 8.1 notification. I allowed it to install and when It booted back up, I had no service at all.
Found this thread, Android 8-1 - How to Edit Cellular APN, and one post in there got me with the phone setup and connected to my computer running ADB commands, which allowed me to at least add an APN.
Adding the standard TRACFONE.VZWENTP apn you can easily find via Google searching fixed the problem. (Had to add mms port of 80 but otherwise, all was perfect)
About a week back I get the 8.1 notification again, which i thought was weird since I was already running 8.1
Turns out it was the April Security Patch for 8.1 (i suppose as that's the only reasoning that makes sense to me right now).
After it installed and did it's thing, I only had 3G service, which around here is prone to many interruptions, aside from the slow speed.
I checked, and it's still using the APN I set up. Nothing has changed on that APN, nor anywhere else I can see.
I even added a new one with the same data, and same thing, 3G.
I've searched the threads here, tried some of the other suggestions but none have worked.
I've even went as far as to get Smail to unlock my bootloader (it's a verizon Pixel XL) and from there I've rooted installed twrp and rooted etc, all in hopes that I could try another method listed in that thread i linked above, using an adb shell with root permissions to view the "default" apn data, thinking maybe something in there is messing it all up.
I had no luck there because even though the phone is rooted now, there was something else I have to do to run an adb shell with root permission and seems the easiest way to get that done is just install a custom rom.
Still, what baffles me is, isn't this what the SIM card is partly for?
And why would software updates disable service, or parts of service?
Seems odd that a software upgrade would effect how the phone uses the service, especially when a custom apn is setup and unchanged.
I have scanned these forums for hours over the past few days and I would really love some direction on what to try next.
Any ideas are appreciated. Thanks!

Play around in the *#*#4636#*#* dialer menu just don't hit the update button beside the smsc input field

Sometimes, the best thing to do is to go to total wireless and ***** at them till they deal with it. I don't think its something you need to stress over. It's Verizon's and Total Wireless's responsibility to get your 4g LTE back. I just dealt with T-Mobile with the same issue. no 4G but call and texting worked. APN set right but they did something on their side and got me back on track after handing them my phone.(in store)

I would but Total Wireless doesn't have a store front or even a kiosk. They're kinda like Straight Talk, but just for Verizon phones. Verizon naturally won't have anything to do with it since I'm paying their competition to use their network.
I had thought about going through the activation again, but when i put my IMEI # on their website now, it says my phone is not compatible. A year ago it said it was, and it has been until this update.
I've considered flashing 8.0 and see if that lets it work again, but I don't like the thought of not being to update my phone or i'll lose parts of my service.
Thanks for the suggestions yall. Will repost if the dialer code leads me somewhere helpful.

They are probably getting money hungry and want people to buy phones from them. There is a big chance that hidden menu could solve your problem though. Regarding the imei the only way that could be a problem is if yours was somehow stolen

I think it shows up as an issue because I'm currently using it. I just tried it again and it said "there was an error." When I tried it a few days ago it had said the same, "there was an error, contact customer support"
It's possible that time it showed up as incompatible i had punched a number in wrong.
Can't confirm if it's the same IMEI i had a year ago but it would be weird if that changed.
Couldn't find anything in the hidden menu except when I checked "Carrier Provisioning Info" showed up that it last attempted it yesterday and had failed.

Well as a last ditch .. just a thought here. Pull the sim power on your phone delete the apn. Perform a reboot insert sim and wait. Still nothing? Check apn add if necessary and reboot. Profit?

I did try that after the april update.
With no APN, I get no service, which first happened right after the first 8.1 update. That lead me to adding the APN.
I haven't tried it since I've unlocked the bootloader.
I will try again before flashing back to 8.0.
8.0 was the last time my phone worked just fine with no custom APNs or anything.
I thank y'all for the ideas.
I would like to know if I'm the only one with this specific problem.
Is anyone else experiencing this issue with the 8.1 updates using a Verizon MVNO?

For future reference that provisional menu will be populated with answers other than no. If you have the proper apn etc..

Want me to take a screenshot of the provisional menu? I don't know what I'm looking for in that menu.
As far as APN, it never needed to make one until the first 8.1 update but all worked fine afterwards. It's only since the April update that I have issues.
Will report back after trying to reset without the sim again

If a fresh image+apn doesn't fix it the only other thing that "you” could try would be replacing the Sim. Sometimes the Sim can fry. Could also be as easy as reseating it.

It's fixed
Here's what I had to do.
I did a wipe install (flash all.bat) of an 8.0 Oreo image as it was the last time I had LTE without even having to do anything (like setup a custom APN etc)
After that was successful, I did a no-wipe install of the 8.1 (April 2018) image, and afterwards, and once it was booted, all was well, I have LTE and everything with no custom APNs needed.
Thanks to everyone who offered help in getting me in the right direction.
In addition to what I previously mentioned that I had tried, I also tried:
-I did try a wipe install of 8.1 a few days ago but still with no success. Even with tweaking APN settings.
-I messed around with the carrier provisioning menu and could see I was not getting LTE and when I told the phone LTE only, then no service at all, so I set it back to LTE/CDMA/UMTS (that's what it was already on.)
-Tried dialer code *228 to "activate" my service, but that had no change.
I went back, this morning, to the thread I first looked at after the first 8.1 update I had which disrupted my service completely and ended up with me using an adb shell to do something that allowed me to add APNs and subsequently setup an APN that worked for me until the 8.1 April security update.

I have this same issue and the only solution I've found is to full wipe go back to 8.0 activate on Verizon's network (I too use a VZN MVNO) and then flash the full 8.1 package without wipe.

I can't say I understand why that worked when a completely fresh wiped install of 8.1 didn't, but it did so I'll take it.
The next thing I was going to try, if it hadn't worked, was changing the radio band in the provisioning menu as that seemed to work for another person.
Either way, all is well for now. Thanks for all the advice!

The only thing I've come up with is that starting on 8.1 flashing full wipe for VZN users (or perhaps limited to VZN MVNO's) with unlocked bootloaders is not allowing the device to activate on the network. I suspect VZN hanky panky at work but I am generally a skeptic that way. Once you get it the way you want it you can update each month with the full firmware but remove the -w in the flash-all.bat file and you should be good.

My bootloader was still locked when these issues began with the first 8.1 update (which adding an APN fixed), and culminated in 3G only after the 8.1 April update.
I only unlocked it so I could hopefully find a solution, which thankfully was a success.
I'm just as skeptic as you are when it comes to VZN though. They have the best coverage in this area, and that's the only positive thing I have to say about them.
