I tried flashing KB5 modem on the AOKP rom for the T-Mobile Vibrant but I cannot seem to bring up anything. Does anyone know if I can input a custom APN that will connect to T-mobile or will I have to give them a call.
Manually input the apn settings.

ICS Modems
Also make sure you flashed the ICSKB5 and not the regular normal one.

I have unlocked my AT&T Galaxy Note by requesting the SIM unlock code from AT&T. I then put in a non-AT&T card (T-Mobile), rebooted the phone and was asked for the network unlock code. I entered the code and it was successful. The T-Mobile SIM card works.
I then went to the APN settings to edit the APN and there was only one, the original one from AT&T (shown as ATT PTA). Strangely, this APN CANNOT be edited OR DELETED. Even when I create a new one and select that new APN, the phone always revert back to the original APN.
My understanding is that once the phone is unlocked, the original APN can be edited OR deleted and I can use another APN (T-mobile, etc.). Can somebody help?
Thanks!
Unlocking the phone does not unlock software areas that att has locked down. Good news is that you can add your own apn in that screen.
On the APN setting screen, press the menu button, then "new apn". Type all of your settings, then hit menu and save. Now you can select your new apn on the APN screen.
You don't have to worry about the pta apn from att. If it's not selected, it's not doing anything.

Thanks for the explanation! As long as I can use the phone in NON-AT&T network, I am happy.
To eliminate that APN you will have to flash a custom rom. You can be stock and custom.
What ^^^^^^^^^^^^^^^^^^^^^^^^ Said....g
He wants to run on T- mobile, would this be his problem, doesn't he need a different modem flashed like for example.. the Blaze modem to run T-mob?

Up until about a month ago that was correct, but t-mobile is migrating to the same bands as at&t so test the connection first.
Just using the stock LF6 modem and the t-mobile APN and live with that for a day or two to see if you are in an area that has been migrated.
If you never see H+ or 4G icons you will have to flash the Blaze modem.
Just a quick update:
The original APN cannot be edited, so I created a new APN and select that. When I press the "back" button and go back to the list of APN, the phone AUTOMATICALLY selected the original APN, not mine.
I selected that again, press back button and waited for 5 minutes (in case the phone trying to update whatever it needs with the new APN). Went back to the list of APN and the original APN was selected again! (???).
Did you save the APN you created?

I did, that's why I was able to select the radio button from the list. So the list shows 2 APN, BUT as soon as I exit, the default APN was reselected.
In this case, a custom rom is needed for APN changes to stick.
I suggest you look in the super thread (top of the general section)
In the stock roms category you'll see a stock (rooted) version of the rom you need.
You can flash this build which allows APN editing and deletion.
Visually the rom is identical to stock, but sets the system permissions via root access to allow those changes.
Once the modification is complete, you can simply reset your counter and unroot to keep a stock device condition.
The beauty of this device is it's simplicity in root/unroot technique...g
Ranger gets the credit for the rom change advice.....I'm just mentioning it again ...g
Thanks for the information all, really helpful!
I flashed a custom ROM just for testing (CWR backup of course) and indeed I was able to change the APN and it sticks! Definitely have to do with my original stock ICS, even though I rooted it.
You can be mostly stock - - that's what I prefer. But our generous developers take the stock rom and tweak it so we can enjoy modifying our phones and be mostly stock. I'm using the Novena rom.
I live in India and use an imported SCH-R970 on Reliance CDMA carrier. Till now I was using stock rom(4.4.2) and everything worked fine. But I recently flashed echoe rom(for i9505). I was able to make calls, but I lost my mobile data. I googled it up and there were a lot of solutions which involved changing APN settings. But I couldn't locate it under settings-more networks-mobile networks(where it is usually located). So I went back to stock and everything was normal. I then came upon apn-conf.xml and these settings differed from the one in echoe rom. So I want to ask can I reflash echoe rom and replace stock apn-conf.xml and get my data back?
PS There is no apn settings even in stock 4.4.2. Please reply ASAP.
So got my phone rooted and ready to accept a custom ROM. Now what ever ROM I flash I get no cellular data. Only when I am on WIFI do I get data. On my status bar it shows my LTE connection to T-Mobile with a ! in it. Am I supposed to flash or do something else when flashing a ROM? I used the latest version of TWRP 3.0.2-0
OK if I revert back to the stock Oxygen OS 2.2.1 ROM it now works fine. What would cause flashing a custom ROM not to have signal?
No data means ur using the wrong cm13 version(i have no data problems on ashwins build.) or maybe your apns just arent configured. Google for your provisers apn configs and set them manually. Also validate that you can see your IMEI on the phone.

You missed the point.

AW OK got what you mean Downloaded Beanstalk CM13 still same problem. Flashes fine then I have no data no signal at all from T-Mobile. Only the stock Oxygen OS ROM works.
Just gave up. Went back to Stock recovery and stock ROM and locked my boot loader. Everything now works as intended. Not sure why all 10 ROM's I tried would flash and load fine but I would have no cell signal strange....
If you need to manually set APN settings go to Settings > SIM cards > SIM 1 settings > APN config.
There click on one APN-setting in the list to open it. Change everything you need, including the name (example: name: Hollandsnieuwe, APN: live.vodafone.com, username: vodafone, password: vodafone, MCC: 204, MNC: 04, APN-type: default, APN-protocol: IPv4, Roaming protocol for APN: IPv4, the rest is blank) then click: Menu > Save. Then go back to the APN list and click the dot right to the entry you just created. Then restart your phone and you should have the new settings active.
By the way: In OOS 2.2.1 you don't have these settings but they are probably already righteous.
I have this problem too but I saw a fix somewhere and cannot find it
Yeah I got it to work finally. It was the APN setting thing. But what is odd is, if I use the T-Mobile APN settings it will not work. If I use MetroPcs (Which T-Mobile owns) then it will work fine. So go figure....

APN is fine. I also have the same APN in other ROMs. I'm also on Telekom.mk (ex T-Mobile Macedonia)
Tmob no.. Roaming +
If I'm on any rom other than OOS I can use data when roaming (99.9% AT&T tower) but have issues with data on T-mobile. However OOS = no roaming data, but no t-mobile data problems. CM 13 and MM roms are useless for a daily driver. I can't recall which MM rom I tried recently but I could not get it to register on t-mobile LTE network even in areas where Tmob was the leading network.
I am getting pretty tired of onyx... I have other network issues with the recent update.

Never ever re-lock your bootloader, it could bug it out so that you can not unlock it again and/or strange things can happen.
Be glad if you are not affected, but if you unlock it again, keep it that way since it's of no disadvantages to have it unlocked.
Hey there, I have the V30 US998 model (bought from US Cellular, my service provider as well) and I'm having issues with my service after flashing.
Stock root works perfectly fine, but when I try to flash any Oreo or Pie room I either get with with perfect SMS and MMS (only works after making a call) with both 4g and 3g running about .3 Mb.....or I don't get any of it working at all.
Is there something I'm missing? Maybe flashing a kernel? I would appreciate all help and advice!
maybe after flashing try adding the corresponding apn for your carrier and see if that helps out with your mms and sms issue. also make a back up of the stock rom with root if swapping roms. it'll be faster than restarting from scratch after a flash.
Make sure your APN is set correctly. This is what's recommended by US Cellular for the V30:
Name: USSC
APN: internet
Proxy: wap.voicestream.com
Port: wap.voicestream.com
Username: [email protected]
password: yourMSID
MCC: 310
MNC: 120
Authentication Type: not set
If "APN type" pops up: default,supl
Not sure why they suggest putting a domain in the port field as I've never had a carrier that used anything there... it's always been "not set" for me. It doesn't make sense logically by basic understanding of the internet but maybe it's something weird and specific to phones and carriers.
Not sure exactly what MSID is but apparently if you call 611 US Cellular can give you it.
Normally nothing "pops up" but that's what their site claims. Usually "APN type" is where you set "default,supl".
To save those APN settings you click the three dots at the top right then select save.
Ultimately, you could nandroid your flashed phone and put your stock US Cellullar ROM back on, record the APN data and flash the nandroid back onto the phone then restore the default APN settings but first I suggest you try to just enter the APN based on the information from the US Cellular site and the below step.
Another thing that could be going on, assuming the APN is set correctly is to enter the following hidden menu with the dialer: *#*#4636#*#* and go select the appropriate preferred network type. For me on ATT I went with "LTE/UMTS auto (PRL)". I think this should work for you as well. This resolved data issues in the past on my Nexus 5 and I had the same problem on the V30+ after flashing a ROM which it also resolved.

I tried to save the APN settings but it failed due to an error? I think it had something to do with either port or the apn type. So I am curious, would grabbing us99820e_02_0910.kdz for US998 (US Cellular) and using LGUP help in this instance? Would all I have to do is reunlock the bootloader and root?

You don't have to re-unlock bootloader. It will stay unlocked unless you re-lock it; please don't. Because to re-unlock you have to temporarily downgrade to pre-July 2018 firmware.
Why US998 20E? Why not the most recent? 20E is older. 20F is most recent You can even flash via TWRP. Just reflash Magisk before rebooting.
You can also enable DTS 3D stereo on US998 20F:
https://forum.xda-developers.com/lg-v30/how-to/enable-dts-3d-stereo-lg-v30-variants-t3887139
At least try it out before you flash back to custom ROM...

I stated before, even flashing back to stock was still giving me issues. I really haven't had much sleep recently due to this issue, so please have patience. I ended up plugging my V30 into my laptop for LG Bridge and it automatically updated to us998 20F. I am hoping its what I needed.

For custom ROMs, you do often have to edit or even create APNs for specific carriers.
Hope stock 20F solves your problem.

Yeah, when I got back home and flashed back to stock, I was only having issues with 4G and it's speed. Just went up to F and I'm still running into them. I also can't edit the apn settings I actually need to change.

Try "add APN", then make it the default.

Also for US CELLULAR, you want LTE/CDMA, right? I of course have where I need for AT&T. Don't use what I have, I'm just showing the options.

I believe US Cellular is one of the last to use CDMA, but I made the apn default but still everything but the first two are still grayed out.
Download 20f zip to sd card in your phone. Go into twrp and go to wipe. Swipe factory reset then go to advanced wipe and wipe the things i have in sceenshot. Then format data. Flash zip. Wipe cache. Reboot system. Make sure you backup anything important because if it is on phone storage it will be gone. You can flash magisk later if your phone works after that. I am on us cellular also.
Before I saw this post I was having problems with cell data, after leaving wifi data will not kick in, I had to go to setting and enable 3g only then LTE and after that, I got data connection, what I did I just dirty flash 20f (I didn't want to lose my info), and everything has been working fine.
PS
I never had a custom rom, it was just converted from sprint to US998, and worked fine for a while and then suddenly started having the data problem

Question, have you gotten any of the Oreo or Pie roms to work nicely with your phone and service? Curious cause now I've fully fixed my phone's service And junk, kinda getting antsy to try out one of them.
Liquidremix worked good but you have to make a call after reboot to get calling and data to work. Right now i prefer stock rooted
After waiting a bit I haven't found any ROMS supporting US Cellular off the bat.
I'm on the latest update US99820G and still having no luck. Anyone else find a fix found a similar post!
I don't have a US Cellular phone (I have the vs996 (Verizon) Frankensteined to US998 - - currently on 20g). For me to install any custom AOSP rom, I have to first do a clean wipe and install the twrp flashable US998 - - 20e rom. I then do a clean wipe and install the AOSP custom Rom of choice (resurrection remix, Liquid Remix, etc.).
If I don't do it this way, then I have problems with data, sound, texts, etc. Again, I don't know if this applies to the US cellular phone or not.
I still have to make a phone call (I call my voice mail) after reboots to get things working.
