I finally got my internet sharing and MMS working on my unlocked Rogers Lumia 900 running on Bell. Earlier this week, I came across this page. http://forums.wpcentral.com/lumia-900/197920.htm. If you follow his instructions (minus the unplugging the cable during the rom flashing), you should have working internet sharing and MMS without having to input any APN settings. The first time I started it with the TelCel rom, I still had to input my APN to get data to work. Then I performed a hard reset by holding volume down, power, and camera buttons. After that, it picked up the correct settings from the sim card and everything works as it's supposed to. The only downside to some people is that now instead of showing "LTE" in the status bar, it shows "4G" and instead of "4G" when you are on the HSPA network, it shows an "H". I think this is a truer representation of the network you are on anyways since HSPA isn't a true 4G network like the American companies would have us believe.
Please note that if you are going to do this, you will lose any unsynced data on your phone and will also have to reinstall all your apps so backup what you need to.

Seems interesting. I will wait for the 7.8 version to come out. I wouldn't want my phone to be stuck at 7.5 for some reason after trying this.

If for some reason it doesn't update to 7.8, you could always just flash the stock Rogers rom back to your phone and then get 7.8.

Have no problem with 4G, sharing and MMS on original AT&T firmware (using my lum with Europe operators).
Could it be a SIM card flag that prevents the sharing, the euro ops SIMS dont have it
Could it be a SIM card flag that prevents the sharing, the euro ops SIMS dont have it but the NA ops do?

May be, may be... But I had problem too with this features, when it worked on a 1st firmware (flashed by AT&T, not by me). Then I decided to flash it on my own via Care Suite (had flashed the earliest firmware, then updated via Zune). Now it works without any problems. After flashing try to not use the Nokia's Network Setup. If sharing would be OK, you could install NNS on your choice
It works for me after doing a hard reset with t) mobile, if I run NetworkSetup then it stops working. If I insert my att sim then it also stops working.

One more datapoint...
Recently unlocked, using Taiwan Cellular unable to tether.
Before installing Network Setup receive message: no data connection found...
After installing Network Setup, "to enable tethering on this device, go to att.com...".
Same SIM card in HD7 allows internet sharing... no problem. So it's not the SIM.
On HD7, data connection shows "H" but on Lum900 showing "4G"... (not a problem, just observation)
Have hard reset with Taiwan SIM, no joy. Reflashed using Nokia Care Suite... same results.
1. It's clear, stay away from Network Settings app. Even overriding APN settings results in same bogus ATT message.
Any point in flashing a pre-8779 rom? One of the TelCel MX or Claro LTE roms?
To flash another RM808 carrier's rom on top of an ATT RM808 device, is it a straight flash with NCS or need to rename files?

Is there any way to get wifi calling on att with an unlocked s9 from best buy? Flashing att firmware or would it be best to get the att model? Must have wifi calling for work reasons and I hate all the bloatware but might not have a choice.
at&t probably blocks it, if you don't get their version. I have an unlocked, but on T-Mobile, and it works.
I flashed the AT&T firmware on my unlocked S9 and wifi calling and video calling worked.
With the stock firmware on the unlocked S9 nether option was there
Can you point me in the direction of a download for the stock firmware for AT&T? I'm wanting to do the same as well, but feeling pretty clueless about where to obtain it. thanks!
Same here. It works for me on T-Mobile
If I flash the att firmware will I still get firmware updates?

if you flash the att firmware or buy it straight from att you will end up a device supporting the same capabilities. So it's down to your tech skills or budget.
Where can I find the latest att firmware? I did not see it on sammobile.
How to
Step 1 Go to this thread for Firmware (thanks @iBowToAndroid)
You will want to go to the link for the U firmware and find the folder with the AT&T userdata file (RB7) download the user data file and the full firmware.
Step 2 Go to this thread to get the modified version of Odin that recognizes the GS9 firmware files. (Thanks @mweinbach and Raymondf )
You will then flash the downloaded files from Step 1 in Odin, after flashing the firmware the phone will boot into recovery and you will need to wipe data and cache.
Thanks so much... that did actually help me... as a fairly tech savvy person who doesn't really get into this stuff much, the lingo I didn't know was leading me astray... I had come across that thread but didn't recognize it as anything that would help me. Thanks again! Onward to bricking my phone!

Thanks for the info. A follow-up question: is it possible to flash it back to the stock unlocked firmware? The reason is that I'll need to use foreign SIM card when I travel overseas.

I have unlocked version on TMobile and wifi calling works just fine.
Do you have to flash the att firmware to the unlocked version in order to get VoLTE? I don’t care about WiFi calling, just hd calling and being able to stay on lte when making a call, rather than have it drop to HSPA during the call.

I understand, but unless att has changed its policies in the last month, if u do not have an imei number on that account that is an att phone with wifi calling it will turn itself off as soon as your phone is interrogated by the network. Theres 100 threads on it , applies to unlocked s8, s7, etc...
Toggle is there because of firmware, not because it works.

Any help/guidance for me??
I have tried a few times to use the March 2018 RB7 files with the ATT user data to get my phone to ATT stock - primarily for the Enhanced LTE (data and voice at the same time), as well as Wifi Calling. I can't get that version to load. I did get a more recent version to load (RK1) - and maybe that is the issue. Just wondering if there is a newer set of files and what specifically I should use (AP,BL... UserData) to get the phone fully set to AT&T. I now have the wifi calling option, just can't get it enabled. Any help is appreciated.

Hello everyone
I have an LG v30+ running stock android 9 with the global v31a rom.
Today I moved to a new carrier, and after installing new sim, the cellular internet works just fine, but voice calls and sms are not working.
I get the "phone not allowed for voice" message and on the taskbar shown on a "MM" icon.
At first I also received an error windows I attached here.
Moving the new sim to another newer xiaomi phone - everything works fine including calls and sms.
Customer service couldn't fix them from their said claiming it's an issue with phone configurations.
Any idea on how to fix this?
Thanks
I just tested another company's sim card and everything works fine.
So it must be some support from the new carrier
Any idea what can be done before I chose another carrier?
What is the model number (Settings -> General -> About phone -> Hardware info)?
Please share a screendump of your Network status screen (Settings -> General -> About phone -> Network). You can blank out the IP address.
Also, please share screendump of the Testing menu Phone information screen (dial *#*#4636#*#* -> Phone information). Scroll it up 3 lines lines so you don't share IMEI, Phone number, IMSI, but so that we can see all the Provisioned lines.
First thing I would try is a Network settings reset (Settings -> General -> Restart & reset -> Network settings reset) then restart the phone.
It is possible that your carrier only provides voice over VoLTE (and SMS over IMS, which is part of the same feature set). That only works if the phone knows the correct settings for your carrier. That would explain why it works with the newer Xiaomi phone. You can check if you have VoLTE settings in the menu (Settings -> Network menu -> Call). Even if the phone does NOT know your carrier, you may be able to configure it through the Hidden menu (depending on your model number). But it is VERY complicated, and you need detailed information from the carrier about the settings to enter.
Or it could be something else entirely.
On a different note, this thread definitely should have been in the Questions section, not in the Guides section.

Not sure why you are calling 31a "global". It's merely the European H930 31a Pie. I've seen a couple of other people use that term and not sure why... It's not "global" in any way than any other KDZ. (EDIT: I see your screenshot where it says global, which is very strange. Is that some setting? That's just weird.)
Unless you actually have an H930 phone, using the H930 KDZ will not give you the H930 bands or anything. You are still using the LTE/HSPA bands that are on your variant. Some people use H930 firmware on H930D/H930DS for different language options and vice versa. So, "global" is quite an exaggeration. Canada H933 has more LTE bands than any of the V30 variants, so it's really the "global" if any are. (But you can't convert to Canada H933 unless you have a compatible North American variant.)
What variant do you have and what country do you live in?
Ahh, so a European H930. Which country are you in, and who is the carrier?

I don't know where you live and what variant you actually have, but you are using EU H930 31a KDZ.
For instance, if you are in India and using Jio carrier, you need India H930DS KDZ as Jio is VoLTE only. But H930 31a doesn't have Jio's VoLTE settings... Using "another carrier" which allows legacy HSPA during phone calles would then be why it works on the other carrier but not Jio. To fix that you would need to flash India region H930DS firmware.
I am not saying you live in India or using Jio -- you didn't give us any information about that. I am just giving a real life example of why your phone would work on one carrier but not another.
Also, some carriers make you register your phone. If you just stick the same SIM card in you had from previous phone, it sees it's a different phone and will throw up an error message like that until you call them or go into store and tell them what "new" phone you are using. The "other carrier" may not be such a control freak.

Since he says he has V30+, I know he doesn't have native H930 phone. There are no H930 V30+. The V30+ are H930G and H930DS and neither on them have firmware numbered "31a".

I see posts from you back in November and you have been on 31a for awhile...
https://forum.xda-developers.com/showpost.php?p=81065243&postcount=852
So, any issues have to be with this new carrier as you have had phone calls on 31a for most of a year now.
Sorry, double post
Thanks everyone for the replies.
@TheDannemand
Some more information about my device:
Country: Israel
Carrier: We4G
Hardware version: LH-H930G.
Looking up using my IMEI number on lg-roms website gives this model: LG V30 Plus TD-LTE
I shared the network menu testing menu you mentioned.
I DO NOT see any VOLTE setting in the Call menu.
I already tried network settings reset.
@ChazzMatt
I have the H930G version. Actually I always follow your guides in that thread to upgrade the version, and I've been on this stock firmware for a year. So it must be something related to the carrier settings I think.
I actually didn't use my country's specific KDZ file as it was released a bit late. I used the european version if I remember well.
Should I flash the local one? According to lg-firmwares and lg-roms website it's this one:
Code:
https://lg-firmwares.com/downloads-file/21127/H930G30a_00_OPEN_IL_OP_0903
Will it have an impact on call services and bands?
Any chance it is really a carrier using VoLTE for calls? I tried asking all kind of questions but didn't get any smart answer from the tech support team.
Also, what do you mean by registering the phone? I never heard about this.
Thanks again!

For some reason I cannot see your attachments. What I wanted to see was (1) whether you have an LTE connection and (2) whether the phone sees VoLTE as provisioned. In truth, I only need the Phone info screen (from the Testing menu) to see that.
I think it is quite plausible that your carrier requires VoLTE to make calls and that your ROM doesn't support it because it doesn't know your carrier. A ROM for your region probably DOES know your carrier (if they are well established). But it's also possible that it doesn't (if they're newer or changed their VoLTE parameters in recent years).
This was my first thought when I read your post and saw that you were on 4G (which should be LTE, although in USA carrier marketing departments have diluted the term to also cover old 3.5G). And I see that it is ChazzMatt's thought too, with the example from Jio India.
I googled We4G to get a clue if they're VoLTE only, but all the links were in Hebrew
Carriers who don't require VoLTE drop the connection to 3G in order to make calls. This works on every phone that supports LTE because it doesn't require knowledge about your carrier.
However VoLTE relies entirely on VoIP and requires an elaborate login to carrier servers, with security and handshaking to prevent illicit use of their network. And the parameters for that are carrier specific. Each phone has a so-called "buffet" of carrier configs known to that ROM. That's why it matters to use a ROM that knows your carrier.
Thanks for the detailed reply.
I think I'll try the local ROM I mentioned. I just want to be sure it doesn't make a clean wipe if I flash Kdz with LG UP. is that so?

Thank you. I see your attachments now.
So you do indeed have LTE connection for your mobile data. But the phone doesn't even pick up VoLTE provisioning -- which is the first and most basic step in supporting VoLTE.
I would definitely try the regional ROM, but you should flash with Refurbish or Partition DL -- which means losing data. Sorry.
In fact, since you're doing a Frankenstein, I would flash back to Nougat first using Partition DL (to update the partition table), perform a Master Reset (it may bootloop until you do), then flash up to Pie. Wait for @ChazzMatt to confirm those steps.
Good luck to you

I really hope I can flash it without losing data. I prefer not to back up all data.
That's what I also did in the previous rom upgrades.
Would that be possible?

I don't see any way to do this safely without losing data. Sorry.
You could skip that carrier and go with one that doesn't require VoLTE (i.e. one which supports the old dropping to 3G for calls). But you won't have the benefits of VoLTE and WiFi Calling. And you may be in the same situation later if that carrier decides to close down their 3G network and go VoLTE only.

Try enabling 'VoLTE Provisioned' on that screen then restarting your phone.
Is there an 'Advanced Calling' menu in Settings?
Two things that might help:
1) Before taking the plunge, put the SIM in your Xiaomi phone and see if you can make a call WITHOUT using VoLTE: One way is if Settings menus allow disabling VoLTE. If no Settings menus, try the same Testing info - Phone info screen and see if VoLTE is provisioned there. I assume it is. But if VoLTE is ALSO not provisioned on the Xiaomi, that means the problem isn't lack of VoLTE on the V30.
2) Just backup the phone using LG Backup, either through Settings -> General menu -> Backup (then transfer file to PC or flash drive) or using LG Bridge. It backs up all app data and most phone settings (though not all). And I was able to use it across different ROM versions and even different ROMs (between H932 and US998).

Yeah, as long as the phone doesn't see it as provisioned, we can forgot about menus and settings.

Hey everyone,
I'm new to flashing phones but have experience flashing other hardware; still, I felt it prudent to ask for some guidance on this being my first attempt:
I have a Straight-Talk phone which is active and working with 4G that I would like to swap the SIM over to use in my Galaxy S10+ from Verizon.
Swapping the SIM without flashing limited the functionality to be contingent on WiFi; 4G would not work correctly.
So I suspect I'll need to flash with unlocked firmware to get it to work properly.
I have downloaded the G975U1_SAU_1.zip which is what I think I'll be needing to pull this off, as well as the latest available download of Odin (3.14.1).
Before I get started, I'd just like to ask some Questions:
Should I leave the intended SIM (Straight-Talk) in the S10+ (Verizon) while I'm flashing, or insert it after the flashing?
Am I using the correct firmware to flash this Verizon phone to work with Strait-Talk? (United States regions)
Also should I back up the intended SIM in some fashion before proceeding with this process (if so what software if any would be advisable for this?)
Is there anything I need to watch out for?
Am I on the right track for what I'm attempting to do?
Thanks in advanced for any help! :highfive:

Insert SIM after flashing. You need the current U1 firmware from sam mobile. You also need the patched version of Odin that's floating around the forums here. No need to backup your SIM, but using Odin will reset your phone to brand new. Nothing that I can think of, you just put the correct Odin file in each slot and hit go. Seems like you're onto it, you need 3 things which are patched Odin, latest firmware, and I think phone drivers so your PC recognizes the phone. Should be able to find these on Samsung website or other parts of the web.
Thanks for the support!
After your encouragement, I rechecked my firmware made sure to acquire the USB Drivers from Samsung.
Successfully flashed the phone and its now working as intended!
:victory:
I used the Frija tool mentioned here to make sure I had the right files.
And the Driver install came from here.

Random questions:
If you start with a Tmobile GM-S975U that is carrier unlocked (got unlock code from tmobile)
Will it work just fine with straight talk? If not Does changing the CSC code work, and to which code?
Is different firmware required? like U1?

The U1 software for the S-10 plus is strait from Samsung and has no carrier bloat. All US S-10 pluses are the same, no matter who the carrier is. That means you can flash any vendors rom as long as you don't go backwards on the bootloader version. The phone gets set up by the simm card installed on the first boot. The good things about the U1 software is there is no vendor bloat and your updates come straight from Samsung. Don't forget, you have to us the customized Odin to flash with.
Deatailed info and Odin link can be found here. https://forum.xda-developers.com/s10-plus/how-to/guide-g975f-flashing-megathread-faqs-t3936704
Thanks for the reply. Should straight talk just work? My friend says data isn’t working on tmo firmware. What firmware and Csc code would work with them?
curious, do mobile Hotspot work, or is carrier still able to block it?
Hi,
I've got a Samsung A50 that I originally got from Xfinity Mobile, a Verizon MVNO. It worked fine when I switched to T-Mobile but wouldn't work on US Mobile, another Verizon MVNO, because on this model you can't change the APN's manually. I suspect that although it was supposed to be unlocked, Xfinity messed with the ROM to make it harder to use on other Verizon services.
Question: Is there a way I could reflash this so it would be a more standard A50, and allow me to edit APN's and then use it on US Mobile. I like the phone, and would love to keep using it but need to be able to manually edit APN's.
thanks for your help.

I suspect that although it was supposed to be unlocked, Xfinity messed with the ROM to make it harder to use on other Verizon services.
Question: Is there afway I could reflash this so it would be a more standard A50, and allow me to edit APN's and then use it on US Mobile. I like the phone, and would love to keep using it but need to be able to manually edit APN's.
thanks for your help.

I'm going to revise and revisit my post so that this goes a little more concisely for anyone who wants to do it in the future - Thanks for hanging in with me Android, too little sleep and time... LOL
Changing your device to VZW CSC - YES So this can certainly be done - XFinity exclusively runs on Verizon's network so your hardware won't give you any issues, you just need new ROM software. Let's start with first things first - did you pay off the device with Xfinity/Comcast and request the code from them to Carrier Unlock (OR carrier unlock it elsewhere) - because we'll need the hardware to be carrier unlocked before we continue too far down the road. I assumed you had - but to generalize it for everyone getting your device carrier unlocked so we CAN change its CSC will be step 1.
1. Make sure your device is Carrier Unlocked - (Will take the sim of any carrier it supports in hardware - not locked to XfinityMobile_ IF you paid off your phone with Xfinity Mobile you can just call them and request an unlock code and they'll send you one - if they can't/won't Samkey has 2 code readers - 1 of them oughta work PM me...
2. Now that you have an unlocked device your hardware will allow you to change CSC flash a new ROM, etc, but you still need the software for that VZW )Verizon) CSC to be available before you can switch your device to it. The vest way to accomplish this purpose is to crossflash yoru device from the carrier specific ROM device you have now the SM-A505U CCT to the SM-A505U1 XAA which is the US multi=carrier rom which wou ld have come with your phone if your bought an unlocked unbranded device fro Samsung direct in the first place - you can turn your unlocked U device into a U1 and back though why you'd want to??? by using the RaymondPatched Odin which will ignore the checks that it's the same model.
The ODIN you shall use for the purpose is the 3.14.1 3B Patched ODIN, and you may find a copy of it in many places one of which is: https://odindownload.club/odin-3-14-1-patched-modded-for-windows/
You shall also need the ROM to flash - it's the ROM for the SM-A505U1 device with the XAA CSC which supports many carriers CSC including yours VZW. One place I like to find such a ROM is at samfw.com but you can use freyja tool and download it directly from Samsung if you wish - you'll just have to work a little harder... If you did this today - this would be the most current rom - just visit the device page for updates US XAA device main page https://samfw.com/firmware/SM-A505U1
Current ROM https://samfw.com/firmware/SM-A505U1/XAA/A505U1UESCCUD2
DL the ROM, unzip it, Make a backup - this will wipe your device and it should to give you a clean install and save probs down the road - use the CSC full file in the Odin slot for CSC not the CSC_Home which will save your data- you don't want to dirty flash a ROM change - the wipe will be better long term... Just backup your stuff first.
Flash your XAA rom to the device- after taking out your SIM of course....
Reboot, insert the VZW Verizon sim - should see that it's setting your device to the Verizon CSC - Profit...
If not, Use Samkey again or the code - but take the 2 off the end for Android 10. Other codes forthcoming to enter engineering - I'm tired just ask...
Good luck

I appreciate your help. I believe USC is US Cellular, but I am using US Mobile, a Verizon MVNO so I would need VZW as my CSC. Would SamKey method allow me to change to VZW?
APN Chooser just shortcuts to the Access Points settings, where the add button and the reset to default are greyed out and not functional.
L!V3_4_XC3SS said:
I have an Xfinity device, what they've done with my device is left the underlying functionality intact, but just hidden the menu - with my formerly carrier locked device I took the action of downloading the APN Chooser app from the play store and was able to access the menu to edit my apn settings in this fashion.
You could also potentially buy a couple of SamKey credits and change your CSC to USC from CCT if the combo rom is installed on that phone, but YMMV depending on what Xfinity did to its rom.
If that fails the stock rom for your device (Your current CSC is CCT for Comcast/Xfinity Mobile) can be downloaded from https://samfw.com/firmware/SM-A505U and flashed with Odin or Heimdall either of which can be downloaded there as well - the latest rom of your phone with the US cellular CSC (carrier/country specific code) USC for settings and software is located at https://samfw.com/firmware/SM-A505U/USC/A505USQSCDUE1 Or you can look through all the roms and see which version you want if you don't want the latest and greatest for some reason.
Once again it will WIPE your device - backup what you want . I think I have an extra samkey credit you can have if you want to try that first hit me up in the PMs --

PS - If you love US Cellular great - flash the Rom in my link- but if you think you might want to change again flash the XAS ROM (US Wholesale multi-carrier) which you can find easily from the first link on SamFW.com or you can use frija tool from the Samsung servers or whichever ROM source you prefer - if you install that one the CSC will switch to the settings of whatever carrier's sim you put in - you can see the carriers included on each rom by searching your model on samfw.com.

There's a good place to edit instead of making you read through the old stuff that's we found out is irrelevant. Comcast and Xfinity which are the same thing and Verizon both love to mess with their ROMS, The really the only way to proceed here and I know it gave you a scary message but if you already have your device unlocked directly from Xfinity they should have given you a code if you asked for one when you paid it off and you obviously have one or else you wouldn't have been able to use a T-Mobile SIM. Since the one-time thing if your device is unlocked it's unlocked perpetually. Which means now you can change by flashing from a single CSC ROM sm-a505u U model crossflash it with the patched Odin by Raymond will work that's 3 14. 1- B3 Patched crossflashb a U1 multi-device XAA rom regardless of whatever scary warning Samkey showed you.

Looks like I was reading too quickly... LOL - Yeah so with the US Mobile MVNO the best route is to do exactly that - change your CSC to VZW which is Verizon which network it's US Mobile MVNO's - and then manually enter the proper settings for your APN once you've inserted that sim - it will likely get you the correct default settings if you reset your network settings in the settings > General >reset network as the Verizon network knows how to handle US mobile sim traffic - but it's not a big deal to enter manually. If you don't have the functionality after a CSC change you'll have to change CSC and flash the VZW Rom which will definitely do the deed -

Thanks! I appreciate it. Fingers crossed.
So I checked the CSC on the phone after Odining a current Verizon firmware, but it is still CCT,CCT,CCT (comcast).
The version SW info is: A505USQSCDUE2/A505UOYNCDUE2/A505USQSCDUE2/A505USQSCDUE2
Using Samkey, it gives me an ominous warning. Says: "Your phone has special carrier settings. It is not recommended to change CSC on this model. Because Security Area (SEC) may get "Relocked" and no way to unlock it again. "
So I bailed. Any ideas? I don't understand the warning. What would happen if I continued? Is there another option?
My phone has android 11, maybe that is the problem?
I am wondering if I should use the patched Odin and try again. Or just dump this phone and buy another? Help is very appreciated.
Ohhkay then... Let's get done for you what you wanted here... full change to VZW as your CSC --- You're not far off - CCT, is Xfinity Mobile - which is an MVNO that runs exclusively on the Verizon (VZW) network so I guess it was close- It would only have switched again if the phone had Xfinity sim into a device with relevant multi-CSC firmware... That being said, - If you want to switch it to Verizon on a device with either the multi-rom XAA or the VZW ROM that you flashed plus a SIM from the relevant network - or if you're a crazy like me who like to use 2 different CSC's on a dual-sim device - you don't even need more codes of SamKey -- do the following methodology and you should get what you want.
Using Google's phone dialer or a dialer of your choice that allows codes to be initialized - if you have stock Samsung phone you can try this minus the outside set of *# #* and see what you get...
Enter the Service Mode on your device as follows: Using the dialer from above type into ita *#*#276633683782#*#* -- This is for Android 11 OneUI 3.0+ take off the 2 for an older version Samsung device if you want to generalize my instructions.
You will enter the engineering menus at (5) RF TEST -- You may not use your normal back key to navigate here, you will exit the menus... Instead you will select the 3 dots top right corner which gives you the options - END, BACK, HELP, WIFI -- End/Back are going to be the ones that are relevant - don't bother with help it's not helpful... Back - the obvious, END, kicks you out of engineering and back to your phone.
Select your only choice - 5 RF TEST - and then a couple more random things (DON'T mess with the settings unless you know what it does) until it kicks you back to the full main menu.
It's going to have options 1-7 and say MAIN MENU at the top - You will be selecting option 1 - PROTOCOL STATE , then at the following menu Select 6 - PROTOCOL SIMULATION which you select and then you will be brought to a 3 option PROTOCOL SIMULATION menu -- Select 2 IMEI PRE CFG SIMULATION - which will take you to a 5 option menu - AP - (YOUR CURRENT CSC) --> and then you get to choose CSC options that you have available to simulate - but the thing is when you reboot after simming it, it will change your CSC settings for real if you've got a SIM and ROM from VZW or the Multi carrier XAA rom. - If you've got a verizon sim you should be able to change the 2 options CSC of AP and NET1 to VZW which will put you where you need to be - or some of the other US carriers... - Change the top 2 (or 3 if you have a dual sim device setup) CSC's to your preference - write them, reboot, It'll see your sim and change to your VZW network you wanted in the first place.
Let me know how this goes for you - I've done everything you can do with that phone - if you've got the right ROM on there which do - I'll bet you can get it to a VZW stock device - install their apps, delete their bloatware with the ADB command line, and you should be good.
Good luck bud, Let me know how it goes..

The first step gets me in HW test, and then I can't get anywhere else.
So thanks for the updating of your ROM and Device specs, and that shed the light necessary for me to understand where we are at with your device...
So the reason this has happened is because this was an originally carrier locked - model U with only a specific carrier's ROM prob the Xfinity CCT - that's the only thing it could give you as far as a CSC which is why SamKey didn't get it done for you. I'll be happy to give you another SamKey code but you won't need it - and I'll also give you a different corrected code for entry intp the menus for the second methodology I spoke about as well...
To fix this situation you'll need:
A copy of the Raymond patch version of Odin which is 3.14.1 3B Patched you can search or here's one place -- https://odindownload.club/odin-3-14-1-patched-modded-for-windows/
It needs to be patched even though you're flashing stock FW because you're going to crossflash a U device to a U1 rom which is fine 'cus it's the same hardware but full official Odin still wouldnt' allow it. This will allow you to flash a rom to your device with the XAA CSC which the multi rom... it supports myriad US carriers including the one you want. VZW...
Remember that you're going to want to backup important data before you execute this procedure - you always want to use the full CSC file in the relevant Odin slot when you change a device's ROM not the HOME_CSC (you can get away with it if you're changing CSC on same rom) because you need a wipe to ensure the best possible flash on your device - don't dirty flash the U1 ROM in an attempt to avoid backup & keep your data it will bring problems down the road.
Take out your sim before flashing the new rom
Flash your SM-A505u device with the orginal CCT CSC to a u1 (originally unlocked) device with the XAA CSC as follows:
Download the latest XAA rom for the sm-A505U1 device
here's one place that usually does a decent speed download:
https://samfw.com/firmware/SM-A505U1 then go choose XAA in the CSC box,
If you did it today this would be the latest ROM https://samfw.com/firmware/SM-A505U1/XAA/A505U1UESCCUD2
I usually recommend the latest unless you have some reason you don't want to increment your bootloader or etc. not usually relevant.
You have the patched ODIN from above, already, so now you DL the latest rom for the U1 device with the XAA CSC (American Multi-rom has a bunch of US CSC's
Extract the ODIN, unzip the Rom zip file into its parts - run the ODIN find the unzipped roms pieces and put them where they go -- except home_csc won't need that one this time. Reboot phone into download/odin mode adb reboot download at the adb prompt ought to do it 4u, and then when it comes up you can flash the rom... as i stated above
After a successful flash/reboot change CSC to VZW by rebooting after you insert the sim card of your preferred network and then it should change you over to the new CSC appropriately. In your case VZW (Verizon) should be on point.
If for some reason it doesn't, I'll give you another samkey credit or you can go for the 2nd method you won't need any credits - enter the service mode by
*#*#197328640#*#* instead of my first code and let's see where that gets us...
You could use this same situation for an international A50 device but you'd have to sub the correct ROM for your region..
Sorry this one was a little convoluted but we'll get there... Maybe I'll come back and clean it when it works for you so it will be more useful to others.

You aren't going to get locked out because you are going to get rid of that RoM that Comcast and Verizon have done a number on you got a proceed by a cross flashing your device which is hardware identical to the U1 unlocked device with the US multi-rom which is the XAA ROM available on samfw.com. Search sm-A505U1 then XAA there will be a bunch of cscs in most every us provider but that's what the xaa multi-rom does.. it gives you an unbranded device and then when you put in that Verizon sim you should switch you over automatically.. in other words with a SIM card from Verizon you should end up with the VZW CSC accordingly... But if not you can use the two methods one of Sam key you certainly welcome to have another credit or two if you need them. You're not going to break your device or leave it permanently locked and you're not getting much utility out of the damn thing anyway as is but I've done Chimera on flashing I've done all sorts of crazy things to the Samsung devices and you really they're pretty hard to break if you really really know what you're doing and how to restore things even from the Qualcomm edl mode I mean that modem is always listening for something you got to cross flash to that XAA ROM once you've done that with patched Odin your device will for all intents and purposes be exactly like the unlocked device that somebody bought directly from Samsung in the first place. I'm not going to attach the xaa ROM for obvious reasons but here's the correct Odin.

Yay! success at last. I can't thank you enough. Did what you said, it flashed fine, and inserted my Verizon sim, and the phone switched right over. Phone works, for data, text and voice!
Interestingly enough, the APN section of settings is still greyed out for adding or editing APN's, but since everything is working, I can live with that.
Best of all, no more Xfinity Mobile branding on the phone!

I'm glad you were able to achieve a good outcome finally brother just had to fully understand where we started before we could get to the finish line-
FYI, I think in this case the grayed APN's are because it's actually being managed by Verizon's high permissioned carrier specific app which has the ability to enable/disable settings which it wants to take over itself and manage this 4u - they will send out configuration info over the air and your device will make the adjustment automatically with no intervention required from Joe User. Verizon is notorious for thinking they know better and doing this sort of thing - Xfinity that you had before runs entirely on the VZW network so you probably had the same thing there... you might be able to get em with an management app or a hiddensettings app if you really want to play around with your APN's but Verizon's thing actually does a pretty good job of keeping you on the network at a decent speed - most people wouldn't be able to improve on the verizon privileged app and it's management anyway so there's not much upside to making minor tweaks.
Hope you enjoy your sojourn on the Verizon network

Howdy all-
I have a similar situation....I have a Galaxy A50 that was previously on Xfinity mobile. I just unlocked it with the code Xfinity provided but it is not working on US Mobile for me. No voice, text or data. USMobile tech support says it could take a day or two to "fully" unlock but I think that is a crock of $hit.
I can't change APNs and Network Operator is greyed out and says Xfinity Mobile with the new US Mobile SIM card installed.
It's my son's phone and I really do not want to wipe it to make it usable on US Mobile. Any way to adjust the settings without wiping the phone?

So you have an unlocked phone orignating with Xfinity Mobile -
I'll tell ya that's a complete crock of **** - just a phone rep not wanting to ruin his call stats actually trying to solve your problem - they don't have the knowledge to do it anyway so don't worry about it. So you want to get it to work on US Cellular's network without any love - which version of Android is it running? 10?
Tell me what it says in the APN if you have access to APN settings... What I'm asking is does it have any correct settings for US Mobile, or is it still pointing to the Xfinity servers (Verizon) because that could very well be the issue is that your phone needs to be provisioned on the network.
I assume your US Mobile sim is active, just not connecting in that hardware? type into the Samsung dialer (Phone) if you haven't changed anything, *#4636#* put another set of *# #* on the outside if you're using google dialer, shift the cell info refresh rate toggle to immediate, and tell me which toggles are set to provisioned. Go ahead and scroll down to the bottom, trigger a carrier provisioning event there and let's see if that gives us anything.
Thanks for taking the time to try to help me out.
I can get to the APN setting screen but when I get there, all that I see is that it says " Access Point Name settings are not available for this user " . I cannot add or edit anything like I have done on other phones (like my GS9 for example).
It is running Android 11 and I 'unlocked' it using the code provided by Xfinity Mobile although it seems the code does not fully unlock the thing.

Yes they are certainly different US Mobile is an MVNO that operates on Tmobile and Verizon, so thanks for making that clear. OK so your phone is unlocked for network but Verizon/Xfinity (operates on Verizon network exclusivey) like to mess around with their roms and there's a secondary lock sometines on these devices which greys out the APN - they dont want the end user to be able to mess with it... first of all do you have the option to reset the APN settings? Sometimes that will push it out as it did for the OP of this thread. I'm not sure I've ever seen a viable solution to access this greyed out APN so type in the code *#4636#* in the default samsung phone dialer and down at the bottom trigger carrier provisioning and see if you can get US Mobile to push out a new APN to your phone first of all. Sorry for the double post - thought the first one was lost. Had a connectivity issue myself... LOL

Thanks for taking the time to try to help me out.
I can get to the APN setting screen but when I get there, all that I see is that it says " Access Point Name settings are not available for this user " . I cannot add or edit anything like I have done on other phones (like my GS9 for example).
It is running Android 11 and I 'unlocked' it using the code provided by Xfinity Mobile although it seems the code does not fully unlock the thing.
I'm trying to get it to work on US Mobile by the way NOT US Cellular (they are different, right?)

Yes they are indeed 2 separate providers, the one you are trying is an MVNO which operates on T-Mobile and Verizon - so good news at least the device is compatible... LOL... so put in the code that I edited my first post to show you *#*#4636#*#* in the google dialer, or if you still have the default Samsung phone app take off the outside set of *# #* and tell me which toggles are on, you can change which bands it operates on, do a ping test for data connectivity, and down at the bottom you should be able to trigger carrier provisioning - do that please, pull the simcard, put it back in, then reboot your device and tell me if any connectivity was restored first of all - that would mean the APN was pushed out by the network to your device. Verizon & Xfiniity have a secondary lock on the APN they **** around with their ROMS so people have a hard time using a device on another network. Annoying. But we'll get it. Let me know where we stand.
Well...I have used that code before on other phones to find out how it is locked etc. When I put it in on the A50, absolutely nothing happens now, unfortunately. I did do the code before the phone was unlocked and the phone was still on Xfinity, and the only lock that was present was the carrier lock. When I got the unlock code from Xfinity and started the phone with a new SIM from USMobile, I did get the prompt for the unlock code and entering the provided code seemed to get me past the Carrier lock. But...still in my current OP situation...
That second prompt when you put in the US Mobile Sim is deceiving - that's what we wanted... 000000 or 123456 probably would have done it - I think it's the same as the SPC (Service Programming Code) there is almost no research in this area that I've been able to find outside of my own, and I'm limited in what I can do because I'm not in possession of an A-50 with the problem so if we get this you're helping others by bearing with me.
Of course the obvious thing that could be done is to just fflash the multi-rom with the US Mobile CSC included, like we did above, but that still won't unlock the APN - it's just likey to populate it with the correct values from the carrier. To do that properly would wipe your son's A50
So let's try to unlock this as it's the first best choice...
Go get this and tell me what it says on the status of your sim - should be nework unlocked but it may show the secondary protection.

This should give you a good shortcut into the APN settings to check and see if you can 1. reset to default if that will give you connectivity, and 2. Add an APN when we unlock the phone

As there are a lot of folks who didn't find this obscure thread who will be happy if we figure it out. Let's try the easy stuff first and then I'll get into the ADB command line stuff and tools and codes if we can't get any love with this . So first let's try to clear the prompt "This user not allowerd to change APN Settinggs, etc.::
Make sure that you are in the range of a known Wifi Network and follow the next steps:
Turn on Wifi and wait for your phone to connect to it
While connected to the Wifi Network, reboot the phone
As soon as the device restarts it will automatically connect to the previous Wifi network
Go to APN settings following the above-mentioned path and check if you are now able to view/edit
OR
Turn Wifi ON
Go to Settings -> Mobile Networks -> Network Operators
A search will be executed and afterward, the list will be populated with one or more Network Operators
Choose the Network Provider from where you bought the SIM card
Go to Access Point Names and add the new APN
Save the data and done.
OR
With Wifi on pull your sim and reboot the phone - once booted reinsert your sim and see if it asks for a code....
Try 000000, if that doesnt' work try 123456
If none of that works We will make the attempt to access the APN settings using ADB which is the command line Android Debug Bridge... if you don't have it installed there are guides on how to do so all over XDA, the ADB shell runs not quite as root but at a much higher privilege than the normal user account, so we'll try it from there if none of those work. I 'm sorry I don't have the device or I'd come back with a definitive how to - but for now we'll have to go trial and error, guarantee we'll figure it out, it's I know Samsung devices in general and they're not that different. Many roads my friend.

My toolbox has utilities that will get it 4 certain if need be.
