[Q] some help please!? - Galaxy S III Q&A, Help & Troubleshooting

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

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?

Hello! I hope i started this in the right thread?

As you dont get network, Check your imei number in about>settings. If it says unknows then you need to restore efs from a backup.

My IMEI is just fine, tho my EFS folder is empty?
Check that your mobile account isnt limited or restricted.
Check your sim in another phone.

I had the same problem once with my phone. Turned out to be the SIM card was shot. Had to get a new SIM.
Maybe a solution
For Unknown CSC:
I had the same problem but since I used a MULTI CSC in my ROM I had to select one to be used.
So in the dialer I typed in: *#272*YOUR_IMEI_SHOULD_BE_TYPED_IN_HERE# and then select the one you want like XEH or XEU, etc.
After it the phone will reboot and maybe will do a wipe but I'm not quite sure. I cannot remember anymore.
Hope I could help.
Ive tried other sims cards inside the phone, nothing new. Ive basicly tried all the basic "trys" but nothing helped. And i dont have a EFS Folder back-up im afraid . . .
Thanks for the response!
My suggestion would be to flash a stock rom and see if it rebuilds the EFS folder .
If it does follow rule one backup your EFS zillions of posts on it .
Note
you do not give us a clue regarding firmware or what you have flashed ion the OP .

Just Change CSC to your country CSC and flash Stock Rom
Hello,
If you are facing issue about CSC than change it to your country/region specific CSC and flash stock ROM. everything will be fine than. All the Instructions and Stock Rom for specific region is given in the below link.

[Q]Corrupt IMEI no efs backup

Hi guys, well i managed to somehow ****up my efs folder and it now says no baseband and imei/imeid.
I have searched and searched for but closes thing i was able to find was using nv writer to write my old imei back onto my phone. The problem is when I *#7284# I have no option to choose DM + ADB + <cant remember other option> I only have PDA or MODEM option.
Please help,

Can you try kTool?
K-tool does not work, which is why Prodigy got me to type a command line in the terminal which backed up my EFS folder manually. Now I have an EFS.IMG This is why i put up the THread Because I knew it was soon someone will be bound to stuff up there EFS.. Which is WHY WE ALL NEED TO BACK UP OUR EFS ASAP before we start modding
But as for recovery its hopeless? Can a box be used to restore the imei? Anyway i can write my imei using nvwriter after somehow solving the problem of not being able to put my phone into diagnostics mode?
Argh! I am going insane, this is looking like a one dear mistake!
I had the exact same problem. Tried MANY things, with no luck. If you got yours from Optus less than 30 days, they will give you a brand new replacement phone .
Try to install a stock rom like 4.0.4... that worked for me on a S1 with the same problem and fixed it!

I have the same issue although it happened to me when I flashed a rom to ROOT my device and I didn't back up the EFS, now it doesn't read the SIM/Network and my Baseband & IMEI are Unknown.
I have tried re-installing the stock firmware etc but still no success...
Anyone have any suggestions?? Or at least how I can update my device status back to normal a pose to 'Modified'.. This was I could maybe submit it through warranty repair.. I have tried to reset my binary count with triangle away (before unrooting) but no success as.. The only thing i've managed to be able to do is unroot my device..
Please help!
Thanks...:fingers-crossed:
if you dont mind about the reading , u can still use your phone flawlessly.. and try the trick "oh im not sure , oh i dont know" and get one replace or u will need jtag i guess.. or maybe ( not sure if it work ) get someone else backup efs and find a way to put your imei in and push it back to your device.. and then repeat same procedure with your original imei ... if u cant remember , take a look at your box.. well..i am just suggesting..not sure if it work...
to get rid of modified , go download sammy official release for your telco or country , flash it with odin but the binary counter remains... good luck to u..

I've got mine on the box i got the phone with, i am not sure how i cna inject mine into it. The nv writer doesnt seem to be working as i can put my phone into DM mode. But if u could backup efs folder and upload it, i can give it a crack. If it won't work, I am still sending my phone away back to Telstra on monday

Would a EFS pro backup.img be ok? or do you want the whole uncompressed folder?
EFS Pro img would be fine (i assume) it's a final shot before i ship it off.
Thanks mate!

I read last night that if you flash the original OTA over your phone it will re write your IMEI number and if Telstra's one is not out just use one from AT&T or Optus etc..
So you can make a back up of your EFS and go from there with re rooting and applying a new baked rom.
Either way if can work or it can not. i see no harm
Anyway here is the EFS taken' just now
you should never share your EFS folder with someone else. Due to the fact each imei is unique.

If so flash modem for your local area network

[Q] Not registered on network

Hello I have a big problem, after I installed a new and updated ROM my phone won't work on any carrier, so here's what happened:
1.I had the ROM FoxHound_Sniper_Wolf_LPD_ICS_GSII_By_SnakeS and it worked great until the GPS started failing so I decided it was time for a change (until now the phone was working flawlessly with carriers and such)
2.I first tried to install the ROM ParanoidAndroid 3+ ROM Galaxy S2 but I forgot to do a wipe first and then I wiped the phone and re-installed the ROM and it still didn't work.
3.I installed WanamLite Clean & Fast JB 4.1.2 v14.3 without errors until I tried to turn on data networking (I had my APN setup by then) and it didn't turn on so I tried calling and this would pop up:"Not registered on network".
4.I try to fix the problem by going to network providers and selecting my network provider and it said: "Unable to connect, try later", so I try selecting the automatic setting and it gave me the same error, so I kept pressing the select automatically setting until it said: "Registered on network" so I try to call again and still gives me the same error "Not registered on network".
5.I try to go back to my old ROM (FoxHound_Sniper_Wolf_LPD_ICS_GSII_By_SnakeS) and it still gave me the error "Not registered on network".
6.I also tried some other ROMs: RR_JB_V3.1.3_AOKP_4.2.1_I9100 and RootBox-JB-i9100-V4.1 and the phone still won't work.
7.I go back to the WanamLite Clean & Fast JB 4.1.2 but this time it's v14.6
PS:it says "emergency calls only" in the drop down menu
info:
county: Israel
carrier: Golan Telecom
phone status: I got it unlocked from the company Cellcom
Network mode: GSM/CDMA (Auto mode)
ROM: WanamLite Clean & Fast JB 4.1.2
Galaxy sII GT-1900T
SSN:-I900TGSMH
Can anyone help me with this please?

Hey man I tried this fix: http://forum.xda-developers.com/showthread.php?p=17587351
and when I did step 3 it was fixed but now I have the generic imei (004999010640000)
all you had to do was checking your IMEI online to see if it was blocked listed.
You now ended up with a generic IMEI.
You followed the first 3 steps right?
Please tell me you backed up the EFS folder.

Does your IMEI match the one under the battery .
If not restore your backed up EFS folder .
Fail to backup its a service centre paid for repair .

If imei and serial number are not corrupted. Check your APN settings. You may want to flash stock rom to see if that works. Backing up efs folder highly recommended.

Dial *#06# in your phone's dailer and if your IMEI matches the IMEI on your phone's box or under battery then its something else.
If it says something like 0049xxxx or null or 0000... Your IMEI is corrupted.
In the case of corrupted IMEI you must have a backup of your EFS folder in order to restore it. If you have backed up your EFS then you're safe. If not.... Only Samsung can fix it for you, provided you have warranty left.
I had the same problem.. my IMEI changed to 0049xxxxxx by installing Custom Rom. Got it fixed for free by Samsung PM me if you want to know how.
