[Q] APN Deleted - MF3 Rooted

Hi all, I'm new to the forum and need some help. I have an MF3 rooted GS4. Last night I did a factory reset and after going through the process, I received a message that said com.android.phone process stopped working. I tried to make a call and had no issues. I was also connected to home wifi so no data issues. Today I added ATT visual voicemail (worked before the reset) and couldn't get an authentication and it said check APN. I go into that and notice the settings are gone and there is no option for Phone or ATT - I also can't access any 4G LTE data. I found some APN settings, entered and then it worked. I then did one more reset to ensure all was well and start from scratch and the processed stopped message showed up again.
Edit: this also shows up each time I restart the phone. Eventually goes away and LTE Data shows up.
Why does the process show up after reboot? Is there anything I can do to make the error go away? Anything wrong with using the APN manually entered if it works?
Thanks for any help you can provide

So I found out that the APN settings stick and I have LTE, but the error shows up twice on each reboot. Hoping someone can help me to get this fixed.

N900W8 refuses to accept SIM/make calls

I have made a prior thread regarding this issue in troubleshooting/help but no-one is biting and I REALLY need this solved. PLEASE.
I'm not a 100% sure how this problem occurred, I believe it was after flashing an S5 custom rom called: "RC Elite S5 Port V16" To my Samsung Galaxy Note 3 (N900W8). From what I was reading it was a ROM that "converts" your note 3 to a note 4 or s5, while still having all the Note 3 features. Another possible cause is trying to use RegionLock Away.apk by Chainfire to essentially(unlock) the phone. I feel like this is the main cause though as this affects the modem on the phone. This isn't the SIM as I tried it in another phone and works fine with calls and texts.
IMEI and serial number show the exact ones on the box. I have the latest updated firmware (stock) from Samsung Kies 3 AND Sammobile. Here is a list of pictures from an app I installed prior "Phone INFO Samsung" from the GooglePlay Store.

I skipped "DEVICE ID" section as it is 100% legitimate IMEI and Serial Number.
My phone doesn't want to register its mobile network anymore. When I try to make a call or text it says:

I was reading online for about 2-3days now for possible solutions that can cure this. Such as:
1. Going into Mobile Networks settings and manually register [failed, details below]
2. Going into Mobile Networks settings, hold home button for 2seconds and then hold power button + home button for 15seconds [failed, details below]
3. Taking out battery while the phone is on and remove the SIM card, clean it and re-insert [failed]
4. Factory Reset [Failed]
5. Wipe Storage and re-flash stock ROM [Failed]
6. Turn on airplane mode, restart and turn off [Failed]
7. Reflash stock firmware without SIM card installed [Failed]
8. Completely discharge the battery, recharge [Failed]
Options 1 & 2 do not work because when I try to access Mobile Network Settings I get this:

The SIM card is inside the phone though...
So what I did is found a mobile network options shortcut "program" from GooglePlay Store and installed it. It allows me to access the menu, which is great! Now, when I try to register the SIM card to my correct service provider (BELL CANADA)...it will make me wait for about 1-2minutes before I get "Unable to register, try later" error...even for automatic registration. Here are some more images from my stock from status info page...

If you look, you can see I have full reception on my toolbar at the top...but, when we look at the actual connections everything is unknown and/or disconnected. Even my phone number!
I tried the factory restore with a stock 4.4.2 ROM from Sammobile/Samsung Kies3 and the issue is still there.
Is there anything that anyone knows that can help me resolve this problem? I tried EVERYTHING i can possibly find on Google.
Thank you very much in advance. This is honestly the more unique problem I have ever encountered and i'm in DIRE need of my phone.

Solution!
Bother, I'm sorry to tell you this but you need to restore to the factory rom, through kies on your pc, and after that go to recovery boot and make a back up of your modem and efs, then wipe all data, system, cache, dalvik and internal SD, install rc lite, and restore model and efs!
This works for me every time this happens when trying out new roms, good luck friend!

Service Provider Update Message with SM-G935U

Hey guys, I just recently installed the SM-G935U over SM-G935T Firmware, everything went well, it was a first time first go. the problem came after I rooted the SM-G935U. At first everything was working right, but after a couple of boot ups I started to get this message "Service Provider Update" "your device will restart to configure features supported by the new SIM card." I already did a factory data reset and that doesn't take away the message. I re-flashed the SM-G935U and it worked, message was gone, at first I thought i had to do with the security policy updates, since I forgot to turn it off the first time. So I turned it off and re-rooted the phone but same thing, after a couple of boot ups the message comes back again. and the problem is that you can do anything on the phone because the message is always there, if you take out the SIM card, everything works normal, but as soon as you put it in the message comes back again. even with the SIM card inside the phone everything on the background seems to work fine, I even get better service that with the SM-G935T firmware, so my question is, what is it that i need to freeze so I don't get this message again, because even when hit OK, the only thing it does is tries to updated but receives an error message and sends you to recovery mode. and when you restart the phone message is still there.
I'll appreciate any help, i would like to try other things before i re-flash The SM-G935U but without root.
Thanks In Advance.

OK I think I found a solution hopefully if someone has this same issue will help them.

No sim at start, no network, IMEI is ok

Hello there,
I undertook to unlock the bootloader of my xperia x compact, of course without saving anything (bye the DRM keys), I then used the fastboot to install Paranoid Android v7.2.3, success after the second attempt.
So the phone started very well, but no SIM card recognized at the start of the phone. Possibly PIN code appeared after 10 min of ignition, loop on the "unlocking in progress" and then nothing, no network.
I have been back several times on the official rom via Sony Companion without success. Last night I tried to flash a rom stock with Flashtool. The operation was going well and oh miracle the sim card was detected directly, so I'm configuring the phone and installing all my applications, a reboot after all that and the SIM card had disappeared again.
Since I tried Flashtool several times without success, downgrade to 6.0.1 either.
After hours and hours of research I still do not have the solution, I have crossed several times on forums for the same kind of symptoms but always accompanied by an absent IMEI, but when I type *#06# my IMEI is displayed correctly .
If someone has already encountered this kind of problem I would love to talk to him. Thanks for reading me
Good night
PS: In other bug, the options for developers who freeze or the camera that does not take a picture (freeze when I want to take a picture)
PS2: sorry for my english guys

Did you select your APN under mobile networks

Yes I have selected my APN, edited as my carrier said. The biggest problem is that the sim card is not detected immediately at startup. And when the sim lock pop up (about 5min after starting the phone) validation of the pin code is much too long to be normal. The code is accepted but I have no network, and when I try to search manually in the settings I have a loop on 'searching'. I think the problem comes from the modem / radio but I do not know too much these points, I just follow tutorials on the internet.

I say start from scratch but use Flashtool

I've already started from scratch with flashtool, several times ...

Some news of my problem.
I have since tried several times to change rom, to flash the modem / radio.
Now my sim card is recognized, but still no network. I have wrote my APN correctly but still nothing.
The network appeared only once after the installation of Paranoid Android, but as in my previous post, after a mobile reboot nothing.
Namely that in the phone information menu, line data service: Disconnected and in this menu enable data connection does not change anything (I can't even enable it). Select radio band gives me 3 choices (Automatic, USA, Japan) and when I click on Automatic I get Set [Automatic] Unsuccessful.
If anyone can help me, I'm really starting to feel hopeless.

Hi, i had the same problem. To enter the pin straight away simply go to the quick settings and check if you have the LTE tile there. If not add it. Then hold down on the LTE tile and it should open mobile data settings and then it takes about 5 seconds and it should ask for pin. I have no idea why it is like so but currently i am on paranoid android 7.3.1 and have no problems. Best wishes!

Hi and thank you for your help
The situation has evolved since, the phone asks for the sim code directly but I still have no network. (see my last message)
Edit : Just noticed that i have an error in flashtool when flashing any rom "those data are not in fsc script and will be skipped reset kernel cmd debug, would you wish to continue ?
Someone ?

Yes all boxes.
Here is my phone info
I can't manage to set radio on

Someone ?

Something similar happened to me recently and it was fixed by selecting my provider via wireless networks > mobile networks > service providers
In my case AT&T was selected when I chose Tmo and rebooted everything was fine. Good luck.

Problem with SIM Card

Hi guys!
I'm from Venezuela, I recently acquired a Nexus 6p (h1511), so yes, I'm a noob. When the cell phone arrived in Venezuela, I connected it to the Wi-Fi network without placing a SIM card, and there was an update notification, I executed it, anyway it already came with Oreo 8.1, the update was December, the one that had It was November. After updating the SIM of the operator Movistar, recognizes it since it says "Without service - Movistar", when trying to call it shows the error "Mobile network not available", when trying to do a network search, it gives error, sometimes to one side of the signal bar, appears an R (Roaming I guess) ... I've been doing a lot of research, believe me I would not be creating this post if I was not so desperate, I have many doubts
I took it to a technician, he looked at it and said it was CDMA that there was nothing to do, he wanted to sell me a GSM motherboard, I told him I would think about it, it was strange for me to be just CDMA, I investigate more and I realize that it's dual, and it changes from MEID to IMEI when I put the SIM card ... I did a factory reset and it did not work. I used the options in *#*#4636#*#* the default is LTE/CDMA/UMTS Auto (PRL) ... I tried to put GSM Only or Auto or any option that included GSM. Without apparent results, I think that it did not even change the default option, the radio bands are few, all from the USA (logical being the USA version of the cell phone) ...
Investigating further, I understood that the problem persists in Android Oreo ... Under the official firmware of Google 7.1.2, I follow the steps, I do the unlocking bootloader, flash vendor / radio, flashing system, in the end there is an error , something about user, I really do not remember, something like that could not erase the user partition or had no permissions ... The issue is that I turn on the cell phone, start to do an erasure, then start asking for google account, etc. ... I configure it, but I see everything the same, I enter the configuration and details of the team, it keeps dialing android 8.1.0, but I see that the base band has changed, some apps have changed, like the application of calls ...
Does anyone know what happened? (And no, the SIM problem was not fixed) :crying:
I want to install this ROM
https://forum.xda-developers.com/nexus-6p/development/rom-chroma-11-08-2015-lockscreen-navbar-t3244444
According to many sites and here in XDA comment that it solves the problem, but this is 6.0.1 ... It means that I must flash 6.0 stock? To install the custom? Or can I install on 8.1?
Any other more updated custom rom that solves this problem?
Thank you! :fingers-crossed:
