[Q] NO REGISTERING ON THE NETWORK NO SERVICE Galaxy s3 mini I8190n

Hello everyone. I bought a samsung galaxy s3 mini version nfc i8190n when lam bought the phone had a problem with GSM and HSDPA network. Do not want to register with any sim card network in any network. The phone has IMEI and modem good. When searching network manually, your phone finds them when I select a network does not register on the network. The phone came with android 4.1.2 baseband version i8190NXXALL6 Number
i8190NXXALL6 CSC: KOR. Before I get to work I saved the foders "efs" and "modemfs". For five days I struggle with it and we did and at the moment I'm stuck and ask for help.
Here are the steps that I did:
1. I changed csc from "kor" in "btu"
2. I rewrote the software with odin. Same i8190NXXALL6 Stock firmware samsung.
3. I installed CWM Recovery and I Flash all versions of this model,modem.
4. I installed custom ROMs, I returned to stock ROMs
5. I installed the stock recovery with odin and he appeared in DOWNLOAD MODE "custom binary download"=yes 2 times;"System Status"=custom;"current binary"=custom. I used the TriangleAWay and I brought "custom binary download=No. I8190NXXALL6 I reinstalled the stock rom via odin with repartition then full erease on the phone Cahe,Data,etc.and returned to" Custom Binay "= No Current Binay = Official Samsung, System status = Officia.Updates software and firmware from samsung works after many writings kind CWM unofficial ROMs, etc.
6. After each writing ROMs I rooted the phone and replaced the file "modemfs" nv.dat file. I downloaded from the XDA forum several files of other users Nv.dat i8190N this model, we have replaced each other and nothing.
7. I deleted all files in EFS folder and modemfs after deletion had baseband XXXXX. IMEI number has remained untouched.
8. I wrote modem manually via CWM recovery and nothing same problem.
I did have searched all the forum and other forums, I searched on google and do not know what to do. My phone is now rooted in the stock rom, stock kernel, stock recovery. These are details which are:

Yes i know but why would you purposely modify the modems and other stuffs, you should have brought it to your network provider service center or samsung and ask them about it, it could just be an SIM card problem

No. Is not sim problem issues becouse i test with a nother sim card`s of diferent carriers. Wen i put a nother sim card in apn setings are the setings for the carrier sim wat ai put,wen i cheange the sim with a nother carrier in the apn setings are the setings of the carrier sim card wat i m put. So for exemple i have 3 sim card`s of diferent carriers and all the sim`s card have pin security cod and the phone ask me for pin, after insert the pin code with all sim card`s don`t register on the netowork but the apn setings of the carrier automatic are there on the setings,so the phone see the sim card for all carriers, in setings wen a search manualy for the netorks the phone see the netowork wen i select the netowork manualy not register on the network,if i select automatic sey "registering on netowrk" but is not becouse if i want to call i can`t "not registering on network" sorry for my english ((

hmm.. as the last solution - search "gsmhosting efs backup request" on google ( ai not able to paste external links here). You will find the backup efs folder from a working sgs3 mini i8190 phone. Flash it to your phone (first keep a backup of yopur own efs before doing this ... just in case)
all the best !

My phone is bricked at this moment. Partition on the phone are mess up. One guy from the Mobile Phones Center brick the phone and my phone is in this stage righ now :http://forum.xda-developers.com/showthread.php?t=2657862 . Wen i have news and solution i post heare. Good day All.

I got the same problem with my phone, it just stopped registering on networks, tried any sim that was available in my country and nothing worked! If you find any solution please update!

Any updates???
Searched and searched... Had a good rooted stock rom, then tried something new a few days ago. I seem to have messed up the modem/bandband. Some issues as the original post. Re-flashed different roms, stock, rooted, unrooted, custom. Tried various different baseband updates. Everything works except being unable to register to the network. IMEI has not changed or been overwritten.
Any help would be gladly accepted.
i8190n

I have the exact same problem. I'm on Orange (EE). Yesterday morning my phone was registered on the network fine, I was in a poor signal area but still on 3G. Then I roamed across the south west of Britain and noticed my phone has no signal. It just wont register on any network, even EE. If I select automatic, it says it registers but it gets no signal and when I try to make a call. It says not registered on network!
The phone is totally stock. My sim works in another phone. I've done a factory reset but the problem still exists.
Was thinking about flashing the ROM but if others have been there too with no fix then I won't waste my time. I keep thinking EE have pushed something to my phone to block access as I'm out of contract by three months and they want me to upgrade!!

Thats good, first install a custome recovery, do a nandroid backup,,,
additionally backup your efs partition, there are many tools, you could do it in some recoveries aswell...
then flash the your original Stock ROM.
there is another posibility, you damaging one of the IC, responsible for bandwitdh/ network - this means you should replace it. You havent still explained how you lost netwrok in the first place.

[Q] Can anybody make a "csc" file for the kitkat?

I had my SM-N900A running fine after i got the update from samsung and lost my kingo root access and it somehow messed up my phone. after playing with the phone a whole lot i can flash kitkat on it. but no matter what i flash or whatever i can not get any type of network. it just weird. i know the csc file supposed to be the network and region operator file. but somehow, someway i can not get any other file for csc except for the MI9. which always failed with that bootloader update that came now. phone is working fine on kitkat it's just that i have no network access. not even the 'ATT' logo won't show up. i went to mobile network under setting and click on it. no success. any help would be appreciated

Can you tell me what your baseband says in the settings menu?

Sorry for the late reply.
Just as I expected, you will need to flash your modem back.
Go here and use the NC2 modem.

I don't really know but I don't think my problem is baseband problem cause I'm running "MLG" rom but when i flash modem/baseband version other than this "mlg" it shows unknown baseband version. Only "MLG" modem is recognized and somehow there's all sort of stuff wrong with this roms/or with my phone. I got that circle sign thingy with the slash in the middle showing I don't have any network at all. Idk... I'm running into all sort of weird stuff with this phone.any full wipe/cleaning with brand new roms or whatever would really help. I just want the phone to make phone calls. Phone is kinda working fine when I flash other modem in it (NC2) (can't make phone call though) but it doesn't recognize the baseband version. Here is another picture with the MLG baseband which it recognized but no network though.

I don't think a csc file is what you need...NC2 is official KitKat, your buildnumber ends with MLG, which means you are on the leaked build of KitKat. Both are 'KitKat', but they're are different firmwares...based on the problems you've described here I think your problems are coming from mixing pieces of MLG and NC2 together. It sounds like you may have some experience with odin from flashing modems, I think the easiest thing to do is to do a full flash to NC2 to clean your system up. This will get rid of the signal issues caused by different modems and you'll have the full NC2 firmware (bootloader, baseband, recovery, etc) for a solid foundation to flash custom roms on
Obligatory warning: once you flash official NC2 you are locked to it and you can NOT downgrade to anything with a lower build number - anything with MLG, MJ5, MI9 is out unless you really really really know what you're doing so definitely read up on that if you're not sure and decide if it's something you want to do.
If it is, it's easy as pie all of the NC2 files you need to flash via Odin are in this thread: http://forum.xda-developers.com/note-3-att/general/n900aucucnc2-odin-files-t2838117
If not, I'd still recommend reflashing full firmware...just MLG though

Not sure what you mean by ime, but a clean flash to NC2 fixex pretty much everything!

URGENT: Re-installed Stock Firmware (update-6.0.1) - NO NETWORK ACCESS

Hey, everyone, I need some help:
On my SM-920G, I re-installed stock 6.0.1 (last official update before 7.0) and, now, I don't have access to the network (says emergency calls only). IMEI and serial number are both intact. What can I do to regain access to my network? I know it's not a motherboard problem because it happened after flashing stock software. I WOULD REALLY APPRECIATE YOUR HELP.
Thank you,
VinceLupe

Did you install the right firmware for your region? You should check that or flash right modem file. If all else fails use kies to restore phone to factory or flash a custom rom and check if everything works.

So, I actually had to have an IMEI change... Long story - but, my question now is: is it possible to return to stock (completely stock) and NOT lose my IMEI number? I've heard some people say, "yes," and O be heard some people say, "no." Is it possible?

I don't think there is any risk of losing IMEI if you flash stock with odin, but if you have root then firstly take an efs backup, just in case, efs is where your IMEI is stored.

If you have root then in the root folder you will find a folder called efs. Just copy it and save it to your SD card or your computer. If you have custom recovery then you can save it from the backup option but I guess that won't help much if you flash stock with odin then it will remove your custom recovery. There are also some apps on the play store but I never used them, I use the first method.

Yeah, I'm just on stock, so that won't work - but, now I have another issue:
So, here's what happened... I got my IMEI changed, and all was good. But, then I realized that my phone was rooted. I tried to flash magisk to have magisk installed, and then my phone wouldn't boot up. Afterwards, I flashed stock to restore official device status, but when I did so, I realized that my network wasn't working. My IMEI (clean IMEI) is still showing, but I DO NOT have any access to my network and can't search the web or anything. What could be the issue, and what is the easiest way to fix it?

Did you flash the correct firmware? The same region as it was when it was working? Flashing a stock rom from a different region sometimes causes this and you need to flash the right one or at least the 'modem' file of the right one to get it working. Or you could use Samsung Kies software to completely recover your phone to its original state when it was bought. Also, What do you mean by saying changed IMEI? Did it not show it correctly or got corrupted and you fixed it? or you changed it completely to a different one from the original?

If you have a good IMEI just call your provider and give them your IMEI and your sim card numbers.

CodeNameRedNeck,
So, I have a good IMEI number, but I cannot register the network service. It tells me "Emergency Calls Only" even though it shows a signal in the top right hand corner. Are you saying that I just need to call TIGO (I am in Bolivia) and register my IMEI number as well the SIM card numbers - or, could it be that there is an even deeper issue? Also, which SIM card numbers are you talking about? Thank you, my friend.

Mufrad,
I completely changed the IMEI to a clean one because, apparently, when I traded for the Note 5 (I am in Bolivia, and that's what people do here), the original IMEI was put on the blacklist. So, now I have a completely different IMEI that is clean (unreported), but I do not have any network access at all - furthermore, when I access the menu using *#0011#, it says "IMEI Status: NG" under IMEI Status. I'm not sure if it's a software problem? I have a friend looking at the phone, but I do not have any idea how it's going because he still hasn't been able to fix it.

When my son switched from an iphone to Android we had to call AT&T and give them those numbers before it worked. I had an Xperia phone that I had to do the same with. There are apps that can read your sim card number. It should also be printed on your sim card.

IMEI and Baseband Unknown HTC Desire 626G+ Dual

I've flashed a recovery.img file of a wrong variant with Official TWRP App and lost my IMEI and Baseband as a result.
Thinking that it'll be fixed by flashing the stock recovery back, I flashed the stock recovery. But it results in nothing.
No IMEI and Baseband yet.
Tried to change IMEI by Chamelphon, MTK Engineering Mode. But they failed.
Deleted the nvram folder too, but nothing seems to be working.
Any idea what to do next?
Samsung stores the IMEI thing in their EFS folder, where in HTC?

I brought my device to a service provider and he repaired my Baseband and IMEI with his Infinity Box and it's fixed then after.
But it now shows CID Error warning! Going on well with this warning so far.

I've, however, already been to this site and tried almost 10 of their custom ROMs just to stay on with the RR-5.8.8 finally. And the cool thing is, custom ROM doesn't give me any CID error.
STOCK one gives always, though. :crying:
Wasn't sure enough if I was supposed to share external links here or not.
Thanks, anyway.
