Hello.
I have a problem which annoys me a lot for a half a year now. Here's the story:
I bought my S3 from secondhand in 2012. It was Android 4.1.2. I was complete newbie that day. When update came off, I wanted to update it via my phone, bu then i threw errors. then i tried it via Kies but also did not managed to. I googled the problem and saw that I am rooted. I listened to people, who said that I should use Odin to upgrade my firmware, So did I. Downloaded latest firmware from sammobile.com. i did everything following the tutorial, but I got the network problem - no connection to the service - no sms, calls, 3g and so on. Only wifi. Then I spend three days trying to google out the problem. Tried almost everything, but as I didint had any backups made for my EFS, and my IMEI was "unknown" as phone said, I assumed that there is nothing i can do there. So I gave phone to the repair service. They fixed it in a day. I got it with the old 4.1.2 firmware version and enjoyed my phone like a year for now. And immediately backed up EFS.
So today I thought that im very bored with this old 4.1.2 and encouraged myself to try upgrade it again. So as I have efs backup, (I also did modem backup) I tried downloading latest 4.3 fimware from sammobile again. (as Im from Lithuania, there is no firmwared for LT, so I downloaded Croatian, because the carrier was the same (Tele2). And here I go again. No network, only wifi. I tried to restore efs, modem - no change with network (Did not managed to recover modem corectly, Odin fails when i want to recover it). then I tried several modems from Perkas file Stash, which i managed install via Odin, but still no change. I truly tried almost every app ant searched every thread in this forum for solution.
Now I tried to flash in to 4.1.2 I9300XXEMG4 firmware. And now im stuck with Samsung logo, mobile does not even turn on.
Any solutions? I will apprecaite any information. Thanks
There is no single solution, once the efs is damaged only a reputable repair centre can recode it properly. If it comes back with 4.1 then it isn't hasn't been fixed properly.

Hi Guys
Done a little digging on this and now have a working phone but I'm confused as to why I can't get it to work factory.
Background info:
S3 international (UK, unlocked), was rooted when I bought it.
Network was present when I put my simcard in and all working. Wanted to go back to factory settings, so followed the guide on totally dubbed (search for "How to un-root & flash a stock ROM – Samsung Galaxy S III – GT-I9300 Totallydubbed" (can't post the link cause of my post count...) to the letter, using Triangle Away and ODIN to install I9300XXEMB5 with BTU radio as linked on here in the official ROMs thread. When I booted up, all I got was Emergency calls only and "Not registered on network" message.
Rooted using CF auto root, still issues. IMEI was not the same as the one under the battery label and the SN had switched to all the zeros. Panic etc. later. Installed BusyBox and the ARIZA patch and I'm back on. EFS folder backed up now. With this working I tried un-rooting again using the same ROM and the same issue came about. Tried flashing back to 4.04 and still had the same issue.
Hassle again, and I'm back to I9300XXEMB5 with BTU, rooted with ARIZA patch.
So the question is can I get back to factory and have working network? I really want OTA updates and didn't buy the phone to mod it yet.
Also the alarm clock is giving me issues... I've read about it being pants and perhaps will get a 3rd party app. Phone on silent and it doesn't sound even though alarm volume is up and media volume is up. My HTC sensation worked fine with the alarm in all scenarios.
Biggest issue is the factor reset and getting it working though
Hey Guys,
First time poster.. so please don't flame me...eh!..LOL
I have searched and better searched without success to my question..
I would like to revert back to JB 4.1.2 on my S3 which is SIM locked to T-Mobile UK, would I need to ROOT the phone beforehand or can I just use Odin and the relevant stock firmware.
would this affect the IMEI and the EFS folder that would make the phone unusable?.
if the procedure is straightforward would I be able to revert back to perhaps 4.1.1 (which would allow me to unlock the SIM myself..).
Hope I have made some sense with my first post..
cheers for any help guys...
4.3 changed your efs to v2. You cannot go back to 4.1.1 unless you have an efs backup from before you upgraded (an efs v1 backup).
Going back to 4.1.2 will work provided you use a firmware EMGx or later (efs v2).
Follow the guides in general stickies on how to flash stock using odin, root afterward with CF auto root.
There are many threads on efs changes, efs 'know this stuff' in particular.

Do you mean this firmware I9300XXEMG4
cheers
cancel all that... I have managed to flash my s3 with the I9300XXEMG4 firmware..... and truth be told I was crapping myself when the phone kept looping on the logo screen.... I did a factory reset and cleared the cache.....all is working.....
just a quick update...
My phone is working fine and dandy with the 4.1.2 stock firmware.... I have also discovered that the SIM is unlocked (or was not locked to begin with), tried a Tesco mobile SIM in it last night and it worked fine, was not asked to input unlocking code for it!
result all round..... :laugh:
You help me too. Thx.
So guys, please explain this to me.
After I did an update to 4.3 the efs was changed. I was ok with that, until my hard drive died and I had lost 4.1.2 backup and so, I can't restore my efs.
The problem is: Can i downgrade to I9300XXEMG4 without problems? I mean, I will not have IMEI and network signal problems? I did flashed some 4.3 roms, but I'm not satisfied with them.
after effect in this downgrading process on my s3
I have upgraded from 4.1.2 XXEMH4 to 4.3 GMJ9 VDI first. liked that very much, display battery backup[battery doctor] was on my phone but drains quickly though in reality with lag issue. i found few things in 4.3:
1. time lag,
2. emulated drive
3. IMEI shows correctly but its SW ver shows 11 instead original 01
there were dozens of good features over above these aforementioned issues.
Sometimes wanted to use Samsung's Indian keyboard, downgraded therefore back to xxemh(4.1.2)..
Problems I found,
a. IMEI shows correctly with original SW version 01 but mobile shuts down suddenly quite frequently.
b. my csc becomes unknown while typing *#1234#
c. Both USB and UART options change to modem every phone boots
d. rooted and found csc folder is missing
e. wifi gpars work but Bluetooth can not be turned ON it becomes gray . sometimes phone hangs when I try to put it ON. it restarts automatically at times.
f. phone lags just like that of 4.3
is there any method settle problems of a., c., e. and f.??

Suggest wipe phone via recovery
Mounts and storage format sd card system cache data .
Boot to download mode and flash stock rom for your network .
Really you need to read and understand THE BASICS STICKIED FAQS AND GUIDES FIRST

@JJEgan, thanks for the reply and tips!

---Mobile is in Vodafone India on my I9300
b. my csc becomes unknown while typing *#1234# [SOLVED]
>. Flash the correct CSC for your network.
--CSC folder has been recovered this way in the process: re-flashed 4.3 (swc) on existing 4.1.2 (xxemh4), sw version of imei changes to version 11 however IMEI remains same, them flashed another itv (4.1.2) as explained in another thread. I lost imei as it becomes 049....
then I flashed back to my country's 4.1.2 (xxemh4). got IMEIand its sw version correctly and my CSC folder also.
EVERYTIME I FLASH I DO FACTORY RESET AND CACHE WIPE compulsorily FROM stock recovery 3(e)
--------------------------
I HAVE BEEN READING A LOT SINCE LAST FIVE DAYS, basics of flashing I guess I know as i have been doing this since 2009[Samsung Bada on GT-S6353]. I use only stock recovery and stock roms. my problems now reduce to:
1. Bluetooth non functional- can not make it ON. When I slide Bluetooth button to make it ON, phone either hangs and restarts automatically or Bluetooth button goes back original OFF position
2. phone's utilities reset to modem automatically [both UART & USB]. I check this when my s3 can not connect to pc or kies to reload my contacts on s3. This is checked by typing *#7284# and I need to set it UART => MODEM & USB => PDA. But these two setting reset to MODEM automatically whenever I check at later stage [when i found pc doesn't recognise s3].
3. phone lags just like 4.3 even in 4.1.2 [xxemh4]
I will do flashing again! Thanks once again!
=================
Flashing done! It doesn't help me
Khaaba,
When your problem solved (Bluetooth, phone lags and so on) please do post here.
I am also facing same issues.
Thanks and regards

Use this link and flash with "I9300XXEMG4_KOR_MULTI_FACTORY". That's the method I followed!
Everything is normal. Then I flashed my country's FW using Odin in PDA mode only!
My friend asked me to look at this phone that was softbricked and kept going to CWM recovery everytime it was booted. I updated the CWM to the latest touch version via ODIN then formatted the phone clean. :good: Then I flashed 4.3.1 stable AOKP ROM and the GApps. It was fine, everything else was working. I connected the wi-fi, used bluetooth, signed into google account everything was normal and stable.:highfive: But then I tried calling and it said "no mobile network". Tried sending a text, could not. I went in and searched for network signals then registered to the correct(I AM SURE!) one.:silly: Still no luck. Then I let it choose automatically. Nothing. Then I thought maybe installing another ROM will somehow fix it and flashed CyanogenMod 10.2 stable. Still no luck. I searched around for a flashable radio but could not decide if that would fix it because as far as I am aware if the radio wasn't working no wireless connectivity should've been either.
The phone is Samsung Galaxy S III GTI9300 white 16GB (unlocked) and has been here in Nepal with Nepal Telecom Sim since it was bought. I have no Idea how the soft brick happened but I think this guy tried to manually update the phone with a stock firmware during which some **** must've happened.
Can you guys please let me know if this could be fixed?
Any help would be highly appreciated.:fingers-crossed::fingers-crossed:
There are hundreds of identical threads, search and read about efs and imei issues.

Hi guys,
A month ago my phone got stuck on Samsung's bootscreen (I was using CM10.2). I tried to restore a nandroid backup but the recovery wasn't able to mount /data, so I had to restore my phone via odin flashing official firmware. Then /efs was corrupted so I lost my IMEI (0049...), therefore I wasn't able to connect to the mobile network (no calls, no data connection...) and I hadn't a backup for that (yes, really dumb). Yesterday I took it to a repair service from a mobile store (definitely not the official one) and they restored my old IMEI number, as I can check it comparing the one behind my battery and the one shown dialing *#06#. But it still doesn't connect to the network, only emergency calls. When I try to call, it displays a message that says that it isn't registered in the network, and if try to register it manually, a toast notification displays saying that it's registered but another one in the notification bar says that the network it's not available.
Things that I've already done without success:
- Back up and restore /efs (kTool).
- Flash CM10.2.
- Flash official firmware.
- Tried with other's SIM (mine works fine in other phones).
Any thoughts? clues? anything that cross your minds? I need to bring my S3 back to life and I don't really know where to begin the research (I googled like hell, though).
I'll appreciate any contribution (even if it's just a description of how network connecting works at low level, codes to check, etc),
Thank you (and please forgive my poor english).
Try patched modern and kernel, if that doesn't work then take it back to your repair store.

Thank you for the quick response, I'll give it a try right now!
EDIT: It worked, thank you!!
I'll explain for others. I had CM10.2 before repairing it following the instructions of boomboomer. I've downloaded the firmware I9300XXUGMK6 from here and flashed it with Odin v3.04. After this, I had to get root again and flash cwm recovery (CF-Root-SGS3-v6.4 with Odin). Then just flashed the two files listed on this post. Now it works again.
Hey everyone, I'm hoping someone is able to point me in the right direction.
I have an S9 Plus with TWRP installed and DevBase v5.9 as the ROM. I have made two backups using TWRP, one from when I first got the phone and a more recent one (within the last week).
When I first got the phone I removed a lot of the bloatware that came with it (Samsung stuff and other junk). After using the phone for a while I realized I needed to keep a couple of the Samsung apps, mostly Samsung Themes and Galaxy Apps (to keep other Samsung Apps up to date). This is where the problems first began.
I restored the backup I made when I first got the phone because I didn't remove any of the bloatware. The backup restored without any problems, I started updating apps, getting it back to the way I had it and noticed I didn't have any reception. I tried to make a phone call and it displayed an error "Not registered on network". I thought something went wrong during the restore, so I tried to restore the phone with the more recent backup I had. That, too, gave me the same message. I checked the IMEI number it was displaying 0000000000000/01. Definitely not my IMEI.
I tried my SIM card in another phone and it worked without any problem. I tried my partners SIM card in my phone and it displayed the same 0000000000000/01 IMEI. I downloaded the latest stock firmware for the phone in an attempt to try and get it back to normal, however, even on stock android it displays 0000000000000/01 IMEI.
So I'm in a sticky situation at the moment. Is there any way to recover from this problem?
