Original imei is gone - Samsung Galaxy S10 Questions & Answers

Hi there. I have some difficult trouble with my imei. After installing an official rom with odin i got my imei1 changed to another one. Beause of that, there is "only emergency calls" displaying and mobile services aren't working.
Smart switch is useless, cuz my phone was previously used by another person i bought it from. So, Switch asks an emergency repair code from an old PC, but the previous owner doesn't have a clue about that code.
Combination rom can't be installed, ofc.
Other roms i've tried to install don't give any result. There were different official roms with different versions and CSC, a couple of customs, separate parts of roms.
Also I've done all possible wipes in different order and different ways.
Additionally, i've tried to change imei1 to my default imei using Magisk Modules, Xposed Modules and terminal emulator.
Soooo, guys, help me please, can i fix it someway?

*bump*

different roms same result--stuck at start up

like the title says ive tried all the roms in the development forum and i keep getting stuck at start up the only one that work is the sprint shipped rom
i think it all started when i tried updating roms to MaxSense UI Style found in this thread
http://forum.xda-developers.com/showthread.php?t=649841
i tried to update by the internal memory method, then it got stuck in the touch logo start up screen and since then the only rom that gets pass that screen is the stock sprint rom
any help will be greatly appreciated
Make sure you have a HardSPL version for CDMA or you will not be able to use custom roms on your device.(Assuming you are on CDMA since you posted this in the CDMA forum) Also make sure you have the correct Radio for your CDMA device, each carrier has their own radios for you to flash.
yea ive flashed my phone with custom roms before so everything should be good in that department atleast, i have no clue whats the issue tho, phones unclocked
o WOW....so i just flashed an old custom rom i was using, and it worked.....
anyone know if now its like a requirement to use MTTY to install the new roms that are out? and if it is would the task 29 command that re formats your phone delete whats on your internal memory too? that would be horrible might just keep this rom if thats the case
I never used MTTY to flash. And I flashed about.... 5 different roms to my phone last night(New roms). Maybe thats why I can't get a data connection? I called up sprint to get my PCS Vision username/password but he wouldnt give it to me and made me press dialer codes to try junk. but the unlock code had changed so we couldnt unlock that part. Anyways the phone is about... 2 years old and I have TEP on it, so they are sending me a BRAND NEW Sprint CDMA Diamond Touch. Will it have the same data issues if I flash custom roms on to that one as well? Do I need the PCS Vision info for Sprint?(Only connection is #777 for Sprint but no idea if I need the login settings)
did you tried installing the original shipped Rom for your phone? or maybe a custom rom made for sprint?
would be good to find the login settings just in case idk
I installed a custom rom MADE for sprint. when the phone starts up it does some sort of..... "Hands Free Activation" but always fails on the data part. saying the PCS Vision username/password is wrong when dialing #777.
I still cannot find out what my username and password would be without calling up sprint AGAIN. They are sending me a new phone and everything, but they have some sort of procedure to get it activated and make your data work I am guessing when I receive the new phone monday/tuesday.
Flash back to the stock ROM for sprint. 2.00* and activate, after that is done, you can flash to whatever ROM you want. I had to do this for my Diam500 and once it activated, I installed Moonscape's ROM and everything works perfect.
I've also never used MTTY nor have I had to do many of the suggested methods of what others' have said. I simply installed WMDC for Win 7 x64 Enterprise, updated all the drivers for my phone, unchecked "fast USB sync" on the phone and voila, I can flash anything.
Just my $0.02
try keeping the dial number #777
all other settings with everything blank
no password

Original CSC [is it important]?

Hello, I've been having a Note5 for quite a while now. Given that I've been having it for more than a year I've begun to flash custom ROMs and Kernels carelessly without backing-up and just experimenting with the. However, with all of this I've also been deleting my original stock ROM backup(s) along with all the data I had (no big deal, everything is on the cloud).
Now I am trying to find out what my original CSC is, given that with every official (or not) flashing there's a different CSC assigned. I've bought my phone outside of the US and it is unlocked, and I am currently using it in the US (with AT&T services).
After my latest change in ROM to an official one I've been trying to figure out what my official CSC is due to malfunctions in some apps, mainly Google Maps. I think Google Maps isn't working because of some hardware damage, or me screwing around with some system files (not EFS, same IMEI as box), however I'd like to see if reverting back to my original stock region would be changing anything.
I've tried several methods to find my stock CSC, including installing "Phone Info" which shows nothing in the "Original CSC" field. I've also tried using all of the *#1234# or *#272*IMEI# command types and nothing shows up just gives me a problem about "IMM" and I've tried everything to fix that but nothing has worked.
Now, on the back of my phone it says "Made in Vietnam". Does this mean that my original stock ROM and CSC most likely is a Vietnam one (such as XXV) or is it not necessarily implied. I've been having the idea that my original stock rom is from UAE (XSG particularly), however I am not certain. I've tried fastboot commands to get original CSC (all phone info in fact) but it seems like fastboot mode isn't showing my device and just gives me "searching for device" message after I type out a command. I tried getting into fastboot mode through adb command but my phone just restarts to normal screen.
So, is my original CSC the XXV, Vietnam version because it says on the back "Made in Vietnam", or not, given that where it was made doesn't mean where it was meant to be sold. I know that region doesn't matter much as long as I am flashing a stock ROM (or Kernel) of the same type (SM-N920C is mine).
Yeah Please Help Him

IMEI Corrupted on ZEROFLTETMO Please help

My IMEI shows 350000000000006. Most of the advice I've seen on this is to flash the stock firmware. I've tried this multiple times and it hasn't worked for me. I don't have a backup of the EFS partition that I can restore, but I do know what the actual IMEI is. I'm not really sure where to go from here. Any help or advice would be greatly appreciated.
Cheers,
Chad
There is no way to fix that, I was facing the same problem after I updated my phone to Nougat, after trying every possible solution i.e. Odin flash, factory reset, contacting T-Mobile, I couldn't find a solution, and I had to get it fixed by a Z3X box, so find a good repair shop with Z3X box, and they will repair it for you, also, changing the IMEI is illegal in some countries, so you may have difficulties finding someone to repair your phone. After the repair, I couldn't upgrade to Nougat and I am stuck with Marshmallow because the Z3X fix didn't support Nougat at that time (a month ago).
My friend asked me to fix her phone and I am seeing the same thing, however when I boot to download mode and use the "show barcode" option (push home button instead of vol+) it shows me the proper IMEI, and the IMEI is also printed on the back of the phone. I thought that maybe because I can still see the IMEI in the "show barcode" that the EFS partition is not corrupt, but I'm starting to think it definitely is...
If I remember correctly you can change your IMEI with an Xposed module.
This had happened to me before theres 2 ways to solve this
Either replace the motherboard with another one
or take it into your carrier and say the sim card doesnt work(make sure its on stock firmware

[HELP] VirtualXposed Dialer App (IMEI Changing)(A10e)

Device: Samsung A10e
Chipset: Exynos 7884
Hi, I was trying to Change my phone's IMEI, but my phone doesnt allow me to unlock bootloader and so I thought nothing can be done about it, because I tried everything from restarting the phone into Recovery mode to Changing the date and time trick... But nothing works...
Today I came across Virtual Xposed and thought this might be a good way to use a different IMEI for my use, but it does not change system settings(which I expected), I also noticed that the IMEI is already changed in this VirtualXposed app env and so I thought i should install some type of dialer and try it out, but I cant seem to find and install any dialer for this purpose, I tried installing a Phone app from somewhere but it doesnt work.
I would appreciate any help to:
Install some Phone app compatible with Virtualapp or VirtualXposed.
Or even an IMEI changer that can work without root on this chipset
or a method to unlock bootloader
