This morning my s3 neo started giving me no signal. I tried different sims but no avail.
Imei is still present, so I doubt a corruption of the efs.
It's become a tablet which doesn't phone...
I've recently gone back to stock and everything was fine for three days, until today.
I've tried using odin to replace the modem.bin and i repeated the firmware re-download.
I can access the STK.apk (that one with the sim menu)
Does anyone have any advice?

Update:
I ended up sending it to Samsung and they fixed it for free lol
Model: AT&T SGH-I337
Baseband: I3377UCUAMF3
Firmware: Stock/SHOstock
I bought a used GS4 on Swappa last week. Got it today, rooted w/ Kingo, and installed Safestrap.
I put in my old sim from my GS3 and can't get service on the stock FW or any SS-safe ROM I've flashed.
- All other radios (Bluetooth, WIFI, NFC, etc.) work with no problems.
- The SIM works on my AT&T GS3 with no problems.
Now the strange part is that the SIM is getting recognized, but is missing certain information. (See screenshot)
+ My phone # shows up and is correct
+ My IMEI is correct and matches the sticker on the back
+ Somehow, signal strength is showing up in service mode
I've attached screenshots of various service mode screens that could be of use.
Now the question is: What should I do/ how do I fix this?
Does this happen on both roms?
Honestly, I'd go get a new sim. Cheers
Yes, I've tried it on stock and 3 ROMs I've flashed.
I'll try my brothers ATT SIM when I get home today.
I'm also going to try removing Safe strap and root, then factory resetting.
Sent from my SGH-I747 using xda app-developers app
- UPDATE -
So I successfully removed Safestrap via ADB, removed root, and factory reset from stock recovery.
The no service problem still persists. I guess the only things it could be now are:
+ My SIM is somehow messed up, as xBeerdroiDx suggested.
or
+ The SIM tray needs to be replaced.
The original owner called me today and affirms that the phone completely worked before.
Does anyone know what else internally could be causing this?
- UPDATE 2 -
OK now I'm at a complete loss. I tried other working AT&T SIMs. Nothing.
Tried replacing the SIM/SD card tray. Also nothing.
I've flashed all stock MF3 and reset EVERYTHING.
I've even gone as far as enabling the service menu and doing a NV_REBUILD multiple times.
Only thing I haven't flashed is a new .PIT because of the signature checking issues with MF3.
It's weird, because I can get a signal if there is no SIM inserted. And I was able to enable data and LTE functionality at one point by messing with the service mode settings. But that was it. No calling or cellular functions.
Could it be that my /EFS partition is somehow corrupt?
I'm getting close to giving up and seeing if Geek Squad can send it in with no warranty/coverage. I don't enjoy having a $400 wifi browser.
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!
Hi. In turkey they do not allow foreign phones, so i stayed there for week and changed my imei through xposed module called IMEI CHANGER. After that i couldnt register on network, so i stayed there without 3g for a week, only wifi. But yesterday i returned to my country put in my sim card, can receive calls and sms. But no mobile data. I flashed different modems, flashed back to stock, but nothing. If someone has cure please share

Pardon if it`s obvious, but did you make sure the APN settings were correct again?
Yeap, that is one of many things i`ve done to get mobile data back
Guys, please help. It`s been 3 days i`ve tried many ways but still no progress. Flashed nb1 stock rom. Tried different modems to access to service mode, which i think problem is there somewhere. When i press back and then input 1 it says menu does not exist. On some pages guys say that its modem related so flashed mf3 and mk2 modems still nothing. Please help. Everything works but no mobile data
Let me preface this with some quick info about the phone. I bought it two years ago and it was SIM locked to Vodafone, Vodafone basically told the guy selling it to me it'd take 6 weeks to unlock so to get around this I went to a third party phone shop who told me they unlocked it but it wasn't until later I realised they had actually changed the IMEI of the device to get it to work. This was okay though, the phone worked fine and didn't give any real issues until two weeks ago.
Two weeks ago my N910F on Kyubi Note 5 Port ROM began telling me "not registered on network" (couldn't make calls, texts or use 3G), I went through standard troubleshooting with my carrier and it didn't appear to be on their end (the SIM worked in a Galaxy S 3 I have spare). I decided to update to 6.0.1 stock from Sammobile using Odin to see if it solved the issue, unfortunately it didn't. I was advised by something I found online to check if the IMEI was blacklisted on Swappa- turned out it was. I brought it back to the shop who had originally changed the IMEI. The guy in the shop told me it wasn't blacklisted but the reason for no service was because the device had a sum of "none" where the serial number should be when you dial *#06#.
He "fixed" the devices by changing the IMEI again and reverting to 4.4.4. He told me not to update it and everything would be fine. Obviously I wasn't too happy with being stuck on KitKat so he told me if I need to come back within 2 weeks after breaking it again that he'll fix it for free. Now the phone on 4.4.4 was giving a serial number and everything appeared fine.
I flashed 6.0.1 onto it and again the S/N became "none", but everything still more or less worked despite this. Since then I have Rooted it, flashed TWRP and installed Xposed. Once I installed Xposed problems began to arise again, the phone is reporting the SD card as corrupted repeatedly, everytime the phone turns on, once finished booting I will get a black screen with just a navigation bar and an empty battery icon (then after 2-3 mins it's fine), 3G wouldn't work at all, wifi passwords aren't being remembered, following boot I get the error message "process system is not responding would you like to close it".
Thankfully I made a backup in TWRP before putting Xposed on the device and restored the system to that this morning, which fixed the 3G issue but all of the other problems are still there (despite not having been there before Xposed was installed).
What should I try now? Should I go back to the guy again? Should I try revert to stock 4.4.4 or 5.1.1 through Odin? I'm really tempted to just cut my losses and sell it, but I love the phone so much. Any help is massively appreciated.

Changing the IMEI is illegal in most countries and therefore the discussion thereof is prohibited on XDA.
Thread closed.
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.
