Unlocked G920T galaxy s6 says "invalid SIM card" after flashing ROM/FRP bypass - Galaxy S6 Q&A, Help & Troubleshooting

Unlocked G920T galaxy s6 says "invalid SIM card" after flashing ROM/FRP bypass
HI everyone, I purchased a used galaxy s6 g920T off ebay and it was unlocked but it had the FRP (factory reset protection) so I couldn't do anything.
I looked for tutorials to reset it and found one that involved flashing the combinational ROM and stock ROM using Odin.
I was succesfully able to get on the home screen now, but the phone pops a message up saying "Invalid SIM card. Network locked SIM inserted".
I'm using a US cellular SIM card (GSM) and it should work. Did I flash the wrong ROM? how can I fix this and get it unlocked so many sim card works?
This is the exact video guide that I followed was "Bypass FRP Google account Samsung S6, S6 Edge, S6 Edge+ (ANDROID 7) (LAST UPDATE)" by the addROM youtube channel if you want to search it, I couldn't post the direct link here.

Hello i think your phone are blocked imei(phone are lost or stolen) go back to ebay and write a seller!

Flash twrp then try to flash MiPa room and select the first csc that is default.

Unlocking Samsung Galaxy S7 G935T

Hello, here what I did, I was looking for any useful information simple way to unlock my Samsung Galaxy S7 G935T ( for factory unlock in order to use on any career) I couldn't found anything very simple for me to do with my zero level skills on how to flash or combine files to unlock my phone. SO what I did is: downloading another Firmware from SAMMOBILE (cost me $25). So I used ODIN so I flashed my phone with a whole new firmware (G935U) the Good thing is that the Previous (G935T) when I switched Sim Card it says : bla bla bla remote unlocking app with T-Mobile) but now instead of showing me this (Bla bla bla ) under the (G935U) it shows only: "Enter Netwok unlock code" anybody here have done this before ?
I need help because my nightmare isn't over yet I still have to bypass this now. Sorry guys I am new to this world.
Thanks for any help. I will appreciate.

Is it actually possible to sim Unlock Samsung Galaxy Note 5 (SM-N920P)

Hi all,
I have been searching in some threads, and I could not find any valuable answer. Is it actually possible to sim unlock (offline) the Galaxy Note 5/Sprint variant ?
I just bought one, and I am living in Burkina Faso. I had it working fine, until I entered the Download Mode screen (out of curiosity). I did nothing special and tried to Cancel out. Unfortunately, OEM unlocking was not off. I got the bootloop screen displaying the Samsung Logo with the red message in the upper-left corner saying "custom binary blocked by frp lock".
I googled a bit then discovered that flashing a stock rom was the solution. I downloaded stock firmware N920PVPS3DQF1_N920PSPT3DQF1_SPR.zip (based on Android 7) and then flashed it via Odin. It went fine, and I could turn on the phone. All the data were there, but no way to get my local sim card to work.
Is there any one who can help here ?
Much thanks in advance.

Hey man many of us in the same predicament. I found that flashing a different modem (CP) will help get some SIM
Capabilities. Not perfect but you can receive and make calls use 3g (no LTE) but cannot send SMS. I'm also searching for solutions
Search Google for " flashing radio for SMN920P" is a .tar file and you flash it via Odin

Samsung Galaxy S10 (SM-G973F) doesn't register to network

I recently bought a used Samsung Galaxy S10 (SM-G973F).
At first glance the phone was in excelent shape. The SIM Card was connecting to the mobile network, and calls, internet connection, etc was OK.
But then, I found out that the phone had been rooted. Probably, by the seller. In pannic, I rushed to unroot flashing the stock Rom.
Here what I did:
1- Forgot to check my precisly CSC code and assumed ZTA (cause I'm from Brazil, and the phone is from carrier "Claro")
2- Downloaded the stock rom using Frija
3- Using Odin 3.14.1 flashed the device.
The previous rooted system was on Android 10 and One UI 2.5. With this new rom went to Android 11 and One UI 3.0.
The problem:
The phone recognizes the SIM Card. But it simply doesn't connect to the network. When I try to make a call it says: " not registered on network"
The phone DO recgonizes the SIM Card. On the SIM Card Manager shows my carrier name (Vivo) and my phone number. Also, the SIM app is showing on the app list.
Things I tried:
Rebooting the phone
Changin the SIM Slot
Testing the SIM on another device to ensure it was working
Checked if the IMEI wasn't missing/undefined. It is not, the IMEI appears to be untouched
Checked if the IMEI had been blacklisted. It's not.
Flashed SEVERAL different stock ROMS with different CSC (ZTO, ZTA, ZVV)
Try to manually select the network. This also throws an error saying "error while searching for network"
I'm really desperate and don't know what to do anymore.
No one have a clue either? :C

How to Fix 'Not Registered on Network' on Android
Here is how to fix 'Not Registered On Network' error on Android. Mostly error occurs on Samsung phones, but this solution works for all android phones.
www.android-recovery.net
Wow,
This is exactly like my S10 right now.
At first, all is good, the signal was great, all working well, except cant connect to samsung pass and samsung health because it was root.
then i brought to sellular shop service, to flash the phone.
Then, “not registered to network” happened. The signal ok, the phone able to read dual simcard, but “emergency call only” and if i try to search network manually, “error while searching for network”
And the sellular shop service have no idea how to fix after they reflashed and try to fix it for several days.
Have you found any solution to fix your pho?
pls advice…

So, were you able to find a solution for this problem? I also bought a Note 9 N960F/DS recently and found out it was actually a N960N model that was changed to N960F/DS. So I did exactly what you did, I flashed the original stock rom, N960N, but now phone will not connect to network. I also did hard reset, reflash other stock roms, nothing changed. Anybody with insight should please give us some pointers.

Question AT&T Z Flip 4 Flashed T-Mobile Firmware But Boot Animation Still AT&T

Wondering if I flashed correctly because the boot animation is still AT&T. I used Odin to flash the latest firmware (F721USQU1AVIA_F721UOYN1AVIA_TMB). Shouldn't the AT&T apps go away and the T-Mobile apps get installed? Bought phone and the seller didn't say it was the AT&T version but instead said it was Samsung unlocked. Anyway, since I'm on T-Mobile I figured there must be a way to put the T-Mobile firmware on the phone. Is that not the case?
Any tips would be appreciated.
Thanks.
First the AT&T apps only appear if you have flashed the firmware and booted up the device with an AT&T sim card inside the phone. Second, if you want to get the T-Mobile variant of the firmware, take out the sim card with your device powered on, reboot your phone, unlock your devide, then insert your T-Mobile SIM card, you should see a pop up saying something, like "restart your device to get carrier features" an on that same pop there should be a button saying "restart" or "ok" or something along the lines of those.
Hmmm I'll try that. The phone had the T-Mobile sim in it when flashed. Should I have not had a sim in at all during the flash?
Thanks
I don't think it really matters if the sim card is out during the flash because I'm pretty sure when you the sim card back in after the device restarts and you then put the card back in you will still need to restart the device to get the carrier software installed.
I wonder if this only applies to Samsung unlocked versions and not the carrier unlocked version because I received no such prompting when the sim was inserted (originally an AT&T sim was in the phone, then I put in my T-Mobile sim).
Did you buy the phone unlocked? You should use the patched version of Odin which can be found [here](https://forum.xda-developers.com/t/patched-odin-3-13-1.3762572/) and download the file labeled 3.14.1_3B_patched. this patched version ignores and bypasses the following conditions
"FAIL! Model mismatch fail" (all PatcheD versions)
"FAIL! SHA256 is invalid" (all PatcheD versions)
"FAIL! Blocked carrier" (PatcheD versions >= 3.14.1)
You can also use the patched Odin to go from carrier firmware to unlocked firmware (which is what I use it for since AT&T takes forever to push updates out)
