I am having hell of problem with my At&t G2 D800. For last 2 months I had issues like INVALID CARD every time I restart/Power off my device.
From last week it got permanent and now I have IMEI=0 , Unknown baseband and Service disabled.
Don't have backup of EFS
Tried Flashing Stock KK Firmware but no way.
Tried to fix IMEI with EFS Professional and it says succeed but after restart its still same.
Can any expert help me or anyone can say is it possible to get my phone fixed? Or should buy a new one

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!
Hello guys
my problem started when I tried to upgrade from 4.4.2 (KitKat) to 5.0.1 (lollipop), I tried first to upgrade using Kies but I just didn't work it recognized my phone and downloaded the firmware but couldn't install, so I went to the other option "odin" I flashed the firmware for my region for my phone yet when it turned on I had a very week signal.
when I tried going back to kitkat I had no service at all and lost my IMEI and baseband, then I tried different regions of lollipop and kitkat, but still nothing, and I thought I lost my IMEI and that I need to write it manually using this box (I don't remember its name) until yesterday when I flashed a Turkish kitkat which restored my IMEI and baseband but still no service, then I backed up my efs folder and went on trying every modem in this thread http://forum.xda-developers.com/showthread.php?t=2192025
I tried everyone of them some gave me "no service" others "emergency calls only" and a third group didn't even recognize the sim card however all of them changed my IMEI to either NULL or the fake IMEI.
now I tried to restore my esf folder but it didn't work, so I thought to re-flash the Turkish firmware (which retrieved my IMEI and serial) but also didn't work and now I still have a fake IMEI which is weird because it worked before.
I tried every method every solution and nothing worked
I even contacted Samsung who told me that it cannot be fixed in Europe cause it is an international model and has to be fixed from where it was bought (Jordan)
and now um feeling really hopeless
please help

Hello everyone,
As this is my first thread, and I have been reading previous assists based on IMEI fixing and couldn't find the answer I am looking for, I really hope that the XDA community can help me fix my Galaxy S4 I9500. I will try to explain the problem the best I can, and I will create a list of every solution I have tried in the 3 week phone fixing saga I have.
1. The problem :
My friend decided he does not need this phone anymore, everything was fine with it except the battery was swollen(but I bought a new one so it doesn't matter). The day before he gave it to me, he accidentaly dropped it in the toilet and it couldn't boot. I opened the phone, cleaned it with alchohol and the phone booted up normally. The thing I noticed was that in the status bar the network symbol was replaced with No signal symbol. I tried 3 SIM cards and none worked. I decided to downgrade to 4.4.2 KitKat version and this is where everything went even worse. I used Odin to downgrade a firmware downloaded from sammobile.com, but I didn't create an /efs backup because I have flashed an Alcatel Idol 2 before and there were no problems with the IMEI or so. It turns out that Samsung devices are different and I am left with NO EFS BACKUP. I know, I should have checked what to do before flashing the device, but what's done is done. The device is doing everything great, there are no problems with Wi-Fi or Bluetooth either, except I cant connect to a network because IMEI is null/null and the Baseband is unknown. The thing is, I am not sure if the IMEI is wiped completely because of a hardware problem, or it's software related because of the /efs folder, because I am not a developer, but a civil engineer...
2. Solutions I've tried so far :
- Flashed many different Android versions;
- Flashed a Lollypop with adonis.pit with Re-partition checked on Odin;
- Tried writing an IMEI and repairing the EFS with Octoplus box;
- Tried flashing an EFS backup from my friend's Galaxy S4 I9500 ( IT IS ILLEGAL IN MANY COUNTRIES, NOT IN MINE, BUT I WANTED TO TRY AND CHANGE THE IMEI LATER SO IT WOULD NOT BE A PROBLEM );
- Tried flashing with a IMEI_null_fix.tar.md5 file which i found on a forum and that didn't fix it either;
- Tried KIES to return the stock ROM but either it does not recognize my device, or it says that my device could not be initialized or so;
- Took the phone to service, but in my town the only service we have is not very professional and they didn't even know the IMEI null does not mean that I will have no wireless connection/bluetooth connection, so they didn't fix it either;
- Tried with EFS Pro, Terminal Emulator and programs similar to those, 3rd party and PlayStore ones;
- Maybe other things but I could not remember because I think I tried everything...
I don't know if the problem can be fixed, but deep inside me I hope that there is a solution, and I think this is the best place to search for help, because it is a great phone and I don't want to throw it away just like that.
Thanks in advance everyone, hope you can come up with a solution.
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.!
