Hello, I have a Galaxy A50 (A505u) purchased in the US. It is originally from Sprint, but I bought it unlocked and it worked on T-mobile. Arriving in Brazil I used a TIM GSM card and it worked, but when switching to a ROM without bloatware the device started to not recognize the data network, always showing the warning of “only emergency call”. How can I fix it?
If you are using custom rom/s, check if your omc is supported

I have an unlocked T-Mobile Samsung Galaxy S4 (SGH-M919) running Cyanogenmod 13 on the latest nightly. So far, I have been getting no service on the T-Mobile network, even after flashing stock TouchWiz. When I inserted a non T-Mobile SIM card, the phone jumped straight on to the AT&T network. I have tried every method found online but to no avail. Please help. I don't even know how a phone tailored for a single carrier can't even go on its network.
Is the phone running the latest bootloader and modem?
I have a Sprint Galaxy S6 (SM-G920P) which has been unlocked domestically and internationally. I currently use Total Wireless (a Verizon MVNO) and my Verizon SIM card works fine in the unlocked Sprint Galaxy S6, though it displays the ROAMING symbol all the time when it is on the Verizon SIM.
I'd like to flash the SM-G920V firmware (Verizon) on to the S6 phone so that it will be Verizon native. Will this work?
I have done the same thing using ODIN on a Galaxy S7 and it worked flawlessly. I have read that all Galaxy S7s are all the same, just each has firmware than unlocks different radios. Is that also true for the S6?
Thanks in advance!
great quetion i also have sprint s6 and i live in europe and i also wanteed to flash stock g920f firmware but i am afraid of bricking it so idk,

If your device has been UICC unlocked then all the radios should work. The Sprint S6 is a "Global" device. I am running mine with a GSM sim card without issue. Flashing anything to a sprint device that isn't made for sprint usually will brick your device if it flashes.If you do some research you will find how to remove that annoying roaming indicator. I know I've seen something about this in the HTC One section before. By the way are you getting LTE with your verizon card installed?
Hi all, I'm hoping someone can answer a few questions before I flash my phone (or waste my time doing so).
I'm using a Verizon Branded Note 10+ (N975U). However, it's carrier unlocked and being used on Total Wireless (a Verizon MVNO - subsidiary of TracFone).
I'm not getting OTA updates because I'm no longer on "real" verizon service. I verified this by waiting 5 weeks for the Android 10 update, and then popped in a friends VZW SIM and got the update instantly. I'm now behind again (Verizon dropped their most recent update over a month ago w/Jan security patch) and receiving "no update available" using the update firmware option in settings.
Additionally, my total wireless SIM can't populate an APN, and I've had nothing but problems with my data as a result. I'm assuming this is because of the VZW CSC, but not sure.
I'm thinking of flashing to the most current U1 firmware, and hoping/assuming this will resolve my problems. Wondering if anyone has any feedback.
If I do it, should I flash the VZW CSC again, or use the TFN CSC for Tracfone, or XAA for default? Do I need to hard reset? Official or Modded Odin? Etc.. Any help would be appreciated.
A little further info: If I put an AT&T SIM card into my phone, it will populate the AT&T APN from the SIM card, so I'm assuming my APN issue is that Total Wireless still uses the VZW CSC, and there's a conflict that Verizon firmware overrides the APN setup aspect. However, my Total Wireless SIM card works perfectly fine and populates the APN on my Unlocked S9+. This is a big part of what makes me think going to U1 will help my issues.
Yes flash the U1, you won't have any issues and will be even better on total wireless. I did the same for MetroPCS

Did it work?
What CSC works for the SM-N975U on Total Wireless?
Thanks in advance!
I recently switched from T-mobile to Verizon , tried to use Verizon SIM card on Note sm-n900t, but Verizon network is not recognized on phone.
the phone is T-mobile unlocked , is this because the base-band firmware on the phone still T-mobile specific? How to fix this?
thanks
Good day everyone!
I recently got a new phone (Galaxy S21), and I saw that you can bring your own phone to Tracfone, so I gave my Verizon S9 (SM-G960U) to my wife (to upgrade her old Samsung Tracfone phone).
We bought and installed the Tracfone SIM card and everything seemed to be working (she could make and take phone calls).
Little did I realize that Tracfone actually also uses WiFi for phone calls, and thus making and taking calls was not using Tracfone's network while connected to WiFi.
When we started researching why her phone did not work outside the home, we found that the CSC is still set to VZW.
This S9 has the latest April 2021 security update from Verizon (Android 10).
I downloaded an older stock Tracfone ROM, but Odin fails with an Auth error (presumably because the phone is not unlocked nor rooted, and the bootloader is locked).
I also tried just flashing the CSC with a Tracfone CSC, but it also failed with an Auth error.
All of the research I have done to this point indicates that Samsung makes flashing Android 10 Galaxy phones very difficult, and I suspect that I am screwed.
Should I put the Verizon SIM card back in and beg Verizon support for an unlock code? Will that even help?
Why doesn't the Tracfone SIM card override the VZW CSC? I thought the SIM card would take precedence.
Thank you in advance, and I hope I am not repeating another thread (I searched, but I couldn't find anything related to changing CSC or rooting a Samsung Galaxy phone running Android 10).
P.S. I have no objections to performing a factory reset of the phone if it will help.
P.P.S. I would like to run the stock Tracfone S9 image so my wife can get the OTA updates, but I'm willing to do whatever to get it working (I would even be happy with running the existing VZW firmware as long as it works).
