Do you have a backup? You messed up your efs folder. Without a backup you need to send it to samsung

can i use efs folder from another i9300?

no

Before jumping to conclusions .
Factory reset check IMEI is correct .
If so flash modem for your local area network

no i dont have my efs backup
oh well just use the phone as MP3 player Camera etc
Or search the restore IMEI threads / restore EFS folder threads might even be in the stickies section .
Next time follow rule one Back up your EFS first ..Rule two is understand before you flash what you are doing as it saves another brick in the SGS2 wall .

If you have root, try this tool if it doesnt work, flash your phone back to stock, reset the flash counter with a USB jig and send it to samsung saying that it suddenly stopped working.
If you have never flashed a custom rom, then just send it back to samsung (Make sure the flash counter is 0 and you have no yellow triangle and that its on the firmware your phone came with)

probability is that the CSC would not have a clue as to who your network is enter network settings manually .
Modem is a question of try each .

i got the mobile back from a local store RAYA and they said they can`t do it cause it is from other region. so i`m totally yours i will try to get the German ROM which have the modem and csc. if there any help i will gladly accept it thanks in advance

[Q] some help please!?

Hi guys,
I'm having some problems with my galaxy s3 GT - I9300, it all started when i tried to unlock it via GalaxSim Unlock.
I started the prosses regulary, making a EFS folder back up (the original EFS).
Then i tried with annother sim but it did not get signal.. here is where I mess up.
I make a factory reset and I lost the ORIGINAL EFS back up.
I make another EFS folder back up, but that back up is not the original, is the one that GalaxSim installs.
My IMEI is the same that the one in the box, also my S/N is not 0000..
So.. I'm wondering if you can help me, maybe i can send you my efs folder to see if it is something wrong.
Thank you very much. I hope someone can help me.
PD: my phone was locked to claro URUGUAY. I'm on 4.2.1 stock
a factory reset does not affect your EFS folders, hence it is still your original EFS folder.
not sure if the sim unlock tool touches the EFS folders though.
flash 4.1.2

Thank you anyway

Ok.. so if galaxsim dos not touch the efs folder, it's the original one.. but i don't know if galaxsim change something or not.
Other thing is that my 3G works, but I can't make any call. It says that I'm not registed in the network
That says wrong IMEI or user has not put network APN settings into phone in most cases .

I have checked again the imei and it's the same as in the box, also the one back the battery.
There is only one change, the last number that appears in the box is 3 and the last one on the phone is 1..

Thank you for quick response..
I'm gonna try ariza again, but some where i have read that is needed a super wipe.
When I try it, I only installed the .apk but it didn't work..
So, it's needed a diferent rom, a wipe or something else?

No idea really... but if you know how to flash a stock rom via ODIN you can try that. If flashing back to stock again doesn't help then you probably need to send to Samsung for repair.
No service as per the basic guides stickied in General section .
Please check your IMEI is correct if not restore your backed up EFS folder .
No EFS backup = no fix .
jje
I've just falshed a official firmware rom again , and still no coverage but at least it recognizes the sim .. If I have this new OFFICIAL ROM , and Flash Counters are reseted , I can go with it to warranty ?
If you have followed all the steps in the guide then you will probably get a warranty repair .
jje
Hi !
I'm sorry, , either you flashed it on Odin with "Clear EFS " box ticked, either you flashed firmware for wrong device. (Ex: i9000 for i9300. )
Anyway if you didn't backup EFS the only issue is Reparation Center.

you might be able to restore service if you flash an MG4 or MG5 official rom through Odin. This is only if you previously used an MG4 or MG5 rom and then flashed some other rom which uses an older modem . read this http://forum.xda-developers.com/showthread.php?t=2377731 and http://forum.xda-developers.com/showthread.php?t=2393289

I don't think it will work.
alexalghisi, can you go in Phone Information and check if you have baseband?
If no, warrently, no luck.
In the black box the phone or modem is Mc2. This is an older modem than MG4. When a ROM that uses an MG4 Modem is flashed , it alters the files in the efs Folder making the folder unreadable for earlier firmwares. If OP had ever flashed an MG4 or MG5 ROM . than an MC2 ROM would not be able to read the EFS. as it can only be used by the newer firmware that can read it. If the folder has not been corrupted than it should work.

Once I solved this issue by flashing a custom rom.. but before it I took backup of efs..

Samsung shv-e210s imei
I had a official Rom 4.4.4 with my samsung korean phone before, i flashed a custom rom then my IMEI-Null, Basband-UNKNOWN, No network. So i try to make it back, i flashed so many patch files according to tutorials on internet. finally my phone bricked i think. i couldnt open even custom recovery. Samsung kies didnt help too, how ever i could open download mode, So i flashed latest korean offical Rom" E210SKSUKNI3_E210SSKTKNI3_E210SKSUKNI3_HOME.tar.md5" using odin. so again i could switch on my phone, then i found my shv-e210s IMEI has changed to new one.my phone back side imei is another one and its original imei. when i insert SIM it show" no service" and network "Unknown" , when i remove SIM it show " limited service" and i can make emgency call simple, and it show some local network providers names, its mean my phone get signals without SIM card and can make emergency calls. Can anyone suggest a method to solve this . if this imei changed by flash files, so it should able to change back to original by anothe file right?
