Hello guys, I am kinda experienced with flashing roms and stuff since I owned galaxy s2 for over a year. However I bought a second hand galaxy S3 one month ago and it has a turkish firmware however when I tried and installed a new rom everything seems to work find except the network service all i see is a circle and has no service and i tried many roms even jelly bean rom (which worked fine with my friend's S3) even i installed the same exact firmware that i had when i got the phone with the same kernel but got nothing :/ then i took it to where i bought it and he told me i can not install any rom on it and just the one i had on it then he took it for like an hour and it was working again... but its really bothering me! what's wrong? i want to install jelly bean or cyanogenmod but afraid to lose the service again i read its something related to radio or stuff? so any help please?? and here is a screenshot of my kernel and rom..
You could have corrupted the efs folder and all he did was restore it from one he backed up, root the phone flash tools and backup your efs then if there are any problems signal or IMEI just restore the efs you backed up.

obs : sry for my english
If you have a backup of your efs then you should be able to restore it, unless you've tried to downgrade to a firmware that your backup is incompatible with.
Read the sticky thread 'efs know this stuff'.

i did my backup when i was in 4.3 , but whenever i try to do the restore , my imei doesnt change and get on factory mode .
As I can read, you tried to restore EFS (4.3 version) in 4.1.2 ROM and it gets Factory mode screen and not valid IMEI code? Right?
If I read right, 4.3 Stock have a new EFS folder not compatible with 4.1.2 older than EMG4, so, try to restore the EFS in 4.3 (your latest firmware by CSC code). Try it and reply when done.
The signal is ok because with or without SIM card/IMEI/EFS you can call emergency (911 ecc...)
Please help me !!!!!!
Hi ! Please help me. By mistake I formatted the EFS data of my Samsung galaxy S3. Now, I don't have the backup also. Now my EFS data is corrupted so I have entered the factory mode. Please say me how to get rid of factory mode and please give me a solution to repair the IMEI problem !! Please help me !!!!!!
I did the restore using hc-ktool but nothing happened :crying:
To get out of factory mode , root the cell , go to EFS folder with any explorer(downloaded in play store) and search for a file named "Factorymod" , edit to ON .
You say you upgraded to 4.3 then went back down to 4.1.2 - upgrading to 4.3 will change your EFS to EFS v2, and 4.1.2 only recognises EFS v1. What you'll need to do is download the stock 4.3 ROM from somewhere like sammobiles so it can read your EFS. Then if you get the 'Emergency Calls Only', try installing Zuluman's patched kernel and ROM:
Patched_XXUGMK6_kernel.zip and Patched_XXUGMK6_modem.zip:

Hope this helps

i didnt understand what u did ... i didnt find this step "Got to Network settings. You need to change Roaming to automatic and CDMA settings to RUIM/SIM (I *think* that is the name of it, I'm actually on TW temporarily as I'm troubleshooting some SDcard issues of my own)
Reboot and you should be back in business. Touchwiz doesn't have a way of changing of those settings which is why ODIN/stock doesn't fix it"
thanks !

Im just sayin if you havnt tried it yet, try flashing CM 10.1.3 and have a look see in settings->more see what options are there - i cant remember what i changed there or what options are available but i can tell you i changed something there aand there isnt to many options there to change anyway so you can kinda figure out what makes sense to change.
The whole thing is pretty simple so its worth a try.
I restored my imei , my method was divine intervention hahahaha , now im stuck on Factory mode . I already changed the file factorymode to ON but nothing changes :/ .

i reinstalled stock rom 4.3 , delete folder EFS with root access and put my efs folder from backup that i did in the first place , i didnt understand why my imei came back to life , because i already did this for whole last week !!! but still was a GREAT solution
the only prlblem now is how i get out of factory mode
Hi guys, I must have read a hundred posts about this issue to no avail.
I recently rooted an old S3 GT I9300 using CF-Auto-Root and Odin. I was sure I backed up the EFS folder, but it would appear I didnt. Now I am runnning the Paranoid Android 3.0 ROM on the device with absolutley no mobile network/signal and although i have the IMEI written down the S/N seems to have changed to a generic 15 digit number as opposed to the original RCF**** or whatever it should be.
Ive tried Kies and re-installing a stock ROM which is both hard to get hold of and doesnt seem to want to unzip from CWM Recovery even after cl;earing the Caches and doing a factory reset. I've also tried re-writting the bin file using a hex code app and terminal with no luck, and EFS Pro only seems to make me think ive restored the EFS by backing up the already corrupt one and restoring that....
It is possible to rectify my EFS issue (nv_data.bin file I assume) with only a written down IMEI and no serial?? if so please advise... as Im seriously stuck and although ive considered using a friends efs folder im sure this is probably illegal...
HELP, Thankyou
oh..and...
It occurs to me that the guy to talk to is spocky12, yet i have yet to pm him pending your advice.... thankyou for any help i may receive..
Hi im also in the same position ive tried loads of stock roms for the UK as thats where i am... to no avail ive tried the original 4.0.1 rom all the way up to the latest 4.4.2 rom and each time the imei number is 0000999......... ive tried modem patches most of which are from looking through the xda site but nothing seems to work.... i could never back the efs up as when i had the phone it was in a constant loop so never knew which software/modem/firm it actually had on it as i could not get past the samsung logo. but since i have flashed latest android for the phone it will boot in fine just wont connect to a network and imei number is wrong ive been days trying to figure this out :crying::crying: Please Help!

Hi Dejay, its good to know im not the only one. have you tried using the Kies program to reinstall stock firmware, did that change anything? Also not sure if you tried this http://www.youtube.com/watch?v=JqLK_2I-SBM method but it didnt work for me, the HEx lines he refers to dont exist in my nv-data.bin.
Coincidentally, thats exactly how i acquired this issue, it stopped booting so i factory reset deviced, then backedup and rooted, then installed custom ROM and somehow lost backed up /efs .Im now showing an 000049 IMEI and tried modem patches, stock roms etc. and no luck. my serials all messed up too and i cant connect to any form of mobile network.
I just changed ROM again as i couldnt get the right Gapps to flash with Paranoid Android Rom 3.0 - now flashing Dirty Unicorns v3.8 from here and all working beautifully except no signal, wrong IMEI and S/N - I am by no means a PRO at all this and so im rather stuck like yourself..
Hopefully we'll be saved?!
Hello,
I have a big issue with my i9300. I flashed PDA: I9300UBUGNK1 Brasil version and I decided to root it using CF-Auto-Root-m0-m0xx-gti9300 .
After root the phone was perfectly working, but I uninstalled some pre-installed games which come with that Brasil version from sammobile and after I woke up after several hours I've noticed that there is no signal. In settings > phone info it says BASEBAND VERSION : unknown and IMEI : null.
I tried to flash again, I've flashed different version, nothing can help. The phone is fully functional WIFI works, only no signal, null imei and unknown baseband version. What the heck I can do before smashing it with a hammer?
And I'm talking about home fixes, as I don't have jig & other professional tools
There is no home fix for imei problems, unless you have an efs backup to restore. Take it to a repair centre and pay them to recode it for you, make sure it works on 4.3 before you accept it back.

As long as the phone is not bricked there should be a home fix... Hopefully
Nobody??
Managed to make it working using an efs backup from a different phone. Now I have to figure out how to put my correct imei instead of that one
Imei now shows 0049
This thread should be closed, indeed a very friendly and helpful community over here ....
A mod, please close this thread
Stop whining, you got the right answer the same day you asked.
Cloning your phone by using the efs backup from another phone is illegal and won't fix the problem anyway.

I didn't wanted to clone another phone and hijack it, please let's remain serious. I just wanted to fix ny efs and that's why I used a backup made from a phone which was broken and was sold by parts.
Now everything was fixed at service
Just a question about k-tool backup
After doing a backup with it I have 2 files
efs.img - 20mb and
efs.tar.gz which has 0 bytes and appear to be damaged as I cannot open it.
Is that efs.img enough in case I lose my imei again after a flash or what?
Hello guys, I had this same problem 2 days ago after flashing the GlamourS4 ROM onto my friend's S3. The flashing failed as it was flashing the modem with an "Assert failed" error, however it still reported that the flashing was successful. On booting the phone it had a null/null IMEI and the baseband was also unknown. I even posted about it on xda.. Yesterday, I found a way to fix both the nul/null IMEI and the unknown baseband. I figured that if I flashed modems onto the phone that the baseband "unknown" message would be fixed, and in the process also fix the IMEI. I therefore searched for patched kernels and modems for it. I came across this page that had patched modems and kernels for the S3 running Android 4.3. I flashed the modems and kernels found on the page with CWM 6.0.4.7 one by one. I went through 6 zipped files before the seventh one fixed my IMEI null/null and baseband "unknown" errors. The one that fixed it was "Patched_XXEMC2_Modem.zip". The six I tried at first changed the IMEI from null to 0049XXXXXXXXXXXXX/XX. The seventh one fixed both problems well. IMEI is well now and the baseband is too. Try flashing the kernels and your phone shall be OK like mine.
Null or 0044....... imei, only repair on service with box and tools... In Serbia, cost 10 euro. Good luck

Ok, so I used to have cm11 installed, but it got sort of buggy in the long run.
I decided to try Foxhound rom, just for kicks... When it was finished installing, I got the default IMEI and the phone wouldnt connect to the network. I found a way to fix this (without backing up my efs folder), by installing an old rom. After that, I installed ef extreme rom (the one with the s5 ui).. It was supposed to be the most stable and smooth rom... But the camera and hotspot wouldnt work -_- ... I never understood why.
Anyhow, the problem is, now that Im trying to get off that crappy touchwiz rom, I NEVER get service anymore. My IMEI will always go blank.. Now the baseband goes "unkown" too (which hadnt happened before)... For ****s sake, I was trying to go back to my old cm11, and still, crazy IMEI... However, if i install the old rom all over again and the region modem: boom, mobile network works again... I dont understand why it fails to work after i have gotten it fixed over and over again...
I even made a backup of my efs folder when the mobile network is working (on the old rom.. Revolution HD)... When i restore it on newer roms, the IMEI and everything comes back.. however, it wont let me access the network (radio off?)
WTF can i do? Im desperate for help, please!!
@niko: standard is to get your actual firmware from sammobile.com & flash it with Odin … to get a stable base.
Your device serial number is probably corrupted. You can use service box to fully repair this issue. Or you can flash Ariza's patched modem. It will work but your efs folder will be permanently screwed and you will be forced to flash it every time you flash a new firmware.
