Hey guys! yesterday I just downgraded my device(i9500) from stock lollipop to cm11 and what I realized was that the network signals were gone. Although phone is detecting sim card as I'm able to see all the saved contacts even I am not signed-in with gmail account. I tried restoring the EFS I made when I was on a custom touchwiz lollipop ROM but I think there's something wrong with that backup as that didn't work for me. I know simply flashing the firmware using ODIN would solve my problem but I haven't got internet connection these days neither time as my exams are going on. I've only got 20MB of data to use everyday. So, I can't download firmware as its size ranges in GB's.
I've installed back stock ROM but problem didn't solve. The problem isn't with IMEI as I'm able too see it. Instead of the network name on the status bar when in lock screen , I'm seeing EMERGENCY CALLS ONLY message
Please help me. Better send me the backup of EFS! Thanks in advance
Could be that your SIM tray broke and it simply coincided with the ROM flash.

Hello guys I need your help, Yesterday I was flashing MIUI ROM for my SM-N900W8 and it was not succesful, so I tried to restore the backup I did before flashing, but the problems started when TWRP did not allowed me to restore, it said Fail... after that I installed the Stock Rom from Odin and everything went ok until I was configuring the phone and when I was willing to connect to my wifi it appeared an error "Unfortunately Remote controls stopped" and the wifi turned to grey and I was not able to use it...
I flashed another stock rom (with operator) and the same issue, searching in the web I was a little deep about knowing what was happening and I realized my Serial Number changed, My IMEI is ok, but the problem persist. I need your help about this and restoring back again my phone. Thanks a lot
me too

I think MIUI messed my phone up too!
My phone stopped radio function. WIFI works fine, but my network isnt being picked up at all. The SIM works though. It saves and deletes contacts properly, but has no signal.
I have been scouring the internet looking for radio images and RUU's. Tried the RUU for my HTC One S, it downgraded my radio hboot...everything to an earlier stock version. Still nothing works.
it changed my device serial number into chinese characters. my phone number is displayed correctly under phone identity.
Anyone have a soloution to this??

In fact the S/N can easily be changed if your phone was rooted. But it is not relating to the wifi issue.
So you may have to try another firmware or another baseband.
Hello!
I have a Galaxy Note 3 SM-N900 that I got from a friend. When my friend gave it to me he still had all his stuff on it so I did a factory reset on the phone. After I reset it the phone had a null IMEI and an unknown baseband. I'm pretty sure the problem is with the modem as I've flashed the stock firmware on the phone several times, I've tried almost all the custom roms on the phone, I've even flashed a whole boatload of different modems.
One of the times I was at school I pulled out my phone to change my music and I noticed it had signal. The phone had signal in different parts of the school and it also had a working IMEI and a baseband. I called 911 to test if the phone worked and the call went through as if the phone never had an issue to begin with. I haven't been able to get any signal on the phone since then. I don't know what else to do and I was hoping someone could help me here! Thanks in advance for those who try to help me!
IMEI Standard answer is to restore your backed up EFS folder as per the faqs and guides .
You may well have a lose connection/ sim within the phone if its intermittent on .
Sadly I don't have a backup of my EFS. I had reset my phone from the settings menu so I didn't think that would cause any problems. Is there anyway I can get a backup of an EFS for the sm-n900 or are there any other solutions?
Is there anyway I can get a backup of an EFS for the sm-n90
NO
You could try flashing a stock lollipop firmware .
Again, I've tried that multiple times already. My EFS folder should be fine if I got signal randomly. My sim contact isn't loose as when I got signal I didn't have a sim in the phone. I think the problem is my modem but if it is I don't even know which modem to use.
Modem for your location/ network .
How do I find the correct modem? I live in the US and my network is MetroPCS
Also, thank you for trying to help me. I honestly appreciate it.
Please help me anyone!
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!

Hi guys I have a problem on my samsung a510f. the phone works properly it's just a bit of time has a problem! after a call placed loses the signal and says (not registered on the network) are forced to restart or put into airplane mode, but the next phone call the problem persists, I tried them all even with changing imei imei changer because I thought that the My iMEI was corrupt but nothing! 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

Hey, I have the same problem, I guess that there's not solution yet.

Do you a have a efs.img backup ? Or any kind of IMEI/EFS/RADIO backup ?
I had the same problem I flashed the stock ROM and somehow I lost my IMEI info, I tried everything and I was even thinking about buying a z3x box but then I decided to do a very risky move , I completely deleted all the EFS related files/info and reflashed again but now I was not able to boot because I always sent me to recovery mode saying that :
"E:Failed To Mount /EFS (invalid argument )"
Then all I did was installing TWRP and rooted my SM-G935F and then I placed my efs.img backup on my internal SD CARD and went on recovery launched the terminal and wrote this :
dd if=/sdcard/efs.img of=/dev/block/platform/155a0000.ufs/by-name/EFS
Then I wrote reboot and it finally my phone was booting and I recovered my IMEI and was able to use my phone normally.
This only works if you have a backup of your EFS, and even if you do is risky , but I did it because I lost all hope and was accepting the fact that my phone would just become a useless wifi only device .
So there is not a fix yet for this problem ?
I have a problem on my s7edge instead. If i have valid imei i'am almost always in emergency calls, and when the signal comes back does not go into mobile data connection. With the wi fi no problem.Can someone help me i'am going crazy.!
