OK so I have this phone I rooted it and backed it up with the stock ROM before playing with it and trying a few custom ROMs some problems occurred with marketing calls so I just was going to revert to stock however my back up wouldn't work for some reason and I got stuck on a loop so I tried another that I made with the Liqiud smooth ROM and it worked but now my phone number is all zeros with a fee numbers at the end I can't make calls or text or get data and I've come to the conclusion that my imei is wrong somehow. I've searched and searched end can't find a fix can someone please point me in the right direction so I can fix this thing

Last night I followed a guide to install galnet miui which involved flashing some "EZ" bootlader. after i was done flashing though my phone wouldn't send or recieve calls, texts or connect to the internet. I flashed back to stock and i still had that problem. Any ideas on what to do? I have checked all the apn settings ect and everythings ok there.
Turns out my IMEI has been changed to a test number that's probably blocked by virgin. Been reading some threads about restoring my IMEI without a backup of my EFS folder. Methods were for the galaxy s2, anyone know if those methods will work?
I have a Note-4 T-Mobile variant(N910T), I have been using Xenon HD and then CM 12.1. After a while when I wanted to go back to stock, and when I flashed stock rom back, the phone was really laggy at first and during setup, there was a popup which said that Factory mode is enabled and I have to switch back to User mode before using it and after a few seconds it disappeared, this happens every time i reboot while in Stock Rom. Somehow after a few minutes, I get the WiFi on again but the keyboard gets stuck after a few presses and phone gets real laggy. After the setup I googled the problem and found out something regarding the EFS Folder, so I rooted it once again and installed ES File explorer and went into EFS and found that it was empty. I tried placing a phone call and it went through and I was also able to use LTE, but when I went to about phone to see IMEI, i saw that the IMEI was also correct, I even tried to setup fingerprints, but it kept saying me to reboot as something was wrong with the fingerprint sensor. Now the weird thing here is that when I am in a Non-touchwiz based Custom Rom, I do not find any lag or any of the problems mentioned above. I have tried these things already:
Going to EFS and switching Factory mode on, but as i told EFS folder is empty.
Backing up EFS from the custom and restoring when I'm in Stock(EFS is empty even in Custom too).
If anyone knows how to fix this, could you please help me?
Thanks!

I did downgrade from 6.0.1 to 5.1.1 but no, I put costom rom but the problem remains, can anyone help me? thanks
I forgot all this has started to happen when the phone was still the original was missing from the root I now had to do to change rom
guys no one can help me?
dont touch the IMEI stuff, you usually either make a backup of it or just stay away from it.
Look what baseband you have, and what bootloader, chances are sometimes they fail to flash, especially after a custom intervention.
I have only tried to change imei thought it was corrupt ... baseband and bootloader are fine....This problem I had since before I performed the root
My imei & baseband went missing after installing a rom. Now i have no mobile network
Hello everyone Happy Holidays i know all us get some kind of technical issue now and then and as far as im concern this isnt the first time someone else has a problem identical to mine which is having a missing imei and baseband resulting in my Samsung Galaxy Note 4 T Mobile popping up a message saying "no mobile network" everytime i try to make a call due to me flashing a new rom. So i dont think there will be a problem if anybody who knows enough about this subject answers how they were able to solve this problem they had.

Usually a result of corrupted efs folder. You just need to restore this folder from a previous backup and you should be good to go.
You should always, always, always, ALWAYS backup your efs folder no matter what device you have. It's a very improbable thing to happen to get this error, but when it does happen it's a pain to get it back and running without a backup of the efs data.
If you do not have this backed up, the only suggestion would be to take it to a repair center if available.

I really appreciate you being a good fellow and trying to help me out but i already solved the problem my installing a new rom. I did restore my Efs back up with Twrp by the way but that didnt help the only thing left was to use octoplus but i found another way around it ?
Just be careful, I used to own a Galaxy Note 1 and it would temporarly fix my problem just flashing stock, but after a few days it went bad again. I never was able to fix it so I gave it to my little sister as a tablet lol
I was flashing a rom and I am pretty new to this so i went to samobile and downloaded a rom and used odin to install it. After that i realised that I could not call anyone or receive data. So I searched it up and found out that my imei on this rom was blacklisted and something about how i should of back up my efs folder. I have spend around 8-12 hours rooting my phone and using various apps. In the end none of them worked and my imei from the back of my phone is different from the one is software.
