Thanks so much for the details, Rahul. Understood everything, but could not understand point no. 3. Rooting of phone ( I know how to root). ..... Wouldn't the Samsung guys want your phone to be NOT Rooted, because if you root it you lose warranty.
So what I want to know is that.... is Rooting required for that Samsung 3G Tool to work? Maybe I can try doing it myself on my laptop with that tool. Sileshnair has given the link to that tool, so I am installing it on my laptop now. Just tell me if root is required for this tool to work?
why we do rooting?
to get access to EFS folder
Efs folder contain your imei number, if the access is prohibited then imei cannot be changed.
even that SAMSUNG 3G TOOL root your phone before Reapir your Imei.
but that tool fail sometimes to root. so beter if you root it manually.
hope u understand my point now

Thanks for the link, Silesh. I installed it on my laptop, but when I open the program it says "Card not found, waiting for connection". Same thing happens if I open this program after connecting my phone to the laptop via USB port.
Ah...I guess I'll have to take the phone to the Service centre only.

Thanks, I understood you. But the only thing I am not able to understand is how did the Service centre accept a rooted phone??? Was it because the Service Centre guy was your friend? Under normal circumstances, the service centre will accept your phone for repair when it is NOT Rooted.
I have the original Stock firmware installed, but I have not rooted it because the service centre guys will ask why did you root it!!
So I am going to take the phone to the service centre which is NOT ROOTED, if they want to Root then they will root it themselves. Right??
You are confusing me by saying take a rooted phone to the service centre.

Hi
i was a happy customer with my SII, which i brought from india, everything was fine, until a week back, when suddenly my SII shows no signal, no IMEI and no baseband
i didnt flashed or changed anything ...
1. i tried using different SIM - no use
2. this sim works in other phones
3. factory reset - no use
4. all is done...
**** I DONT HAVE A EFS BACKUP ***********
please give me a detailed fix route for this issue. as i cannot take the phone to INDIA in next 4 months to get is repaired. i have my warranty still. but thought that something can be done from my side to get it fixed. please please lemme know how to fix this! :-(
I had this happen to me. I hadn't taken an efs backup and thought I was screwed, but I found an auto backup on my SD card called EFS_BACKUP. Check if you have this, if you do, use GSII_Repair from the market to restore it.

If your EFS is not total screwed and your nv_data backup is valid its possible GSII_Repair from market will work for you ...
Once you have tried all the guides and still in the same situation, check out this post
http://forum.xda-developers.com/showthread.php?t=1372169
I tried already flashing the Stock ROM once, and hence i dont know whether there is still a backup of EFS is in place....
can anyone take a little bit more time in explaining the steps to solve this,
like does a backup from another gSII will help the purpose... ?
please let me know more details, i will be thankfull like anything.
How come this problem happens, when we do a complete flash does the EFS folder get replaced or the the flash doesnot affect the EFS part at all?
i feel its very strange to see such kinda problem..
buying Z3x isnt a good idea
Z3x-box sa
msung - 169USD
Z3x-box LG - 169USD

what you call its as total screwed??
Will a backup from another Samsung Galaxy SII work ? for me?
EFS is a folder would be having NV_data and some other files. he's asking that the entire EFS got screwed or just some parts.?
I tried complete flash, means baseband,Kernel and system including User data reset.
i really confused about the relationship between the EFS folder and the IMEI,basband, blah blah...
EFS folder is nothing to with your blah blah nor your modem /baseband .
It is essential the details of the phone and its sole identity that is signified by the IMEI number individual to each phone . This IMEI number is used in the initial handshake each time you make a connection .
Lost or stolen phones can have their IMEI blocked once on the block list handshake is denied by the networks = no connection .

GSII_Repair tool from Market, Four steps in that tool, am Done ...........all is well now.
Really really helpful tool. Thanks to all who suggested this TOOL ;-)

u mean is that a nw problem? nothing to do with the phone?
its really p***d off me for fixing that issue..
handshaking happens only after the phone detects the sim card. but here phone doesnot detect the sim at all. so is ur point still valid?
my phone was brought from samsung authorized dealer so how come its possible to happen so?
looks like EFS is the area where full flash no longer having access to it!! if not then a complete flash should have sorted that out.
EFS are reference files containing the imei and phone unique info, when these files gets corrupted, then phone will b helpless.
though u have root access u'll never get RW permission inside the folder.
there should be a automatic recovery, the SW should have had in place if there are corruption. poor implementation.... bah...
Hi everyone,
As i wrote before on xda (my topic), i disrupted my device's touchscreen while doing TriangleAway process. Then i tried many ways to recover but i convinced that it's not possible to fix it without changing the touchscreen parts. I left my device to warranty and they fixed in 15 mins. and it works great as before.
But now, i have another issue. While i was trying to recover my touchscreen i flashed official firmwares (downladed from sammobile) and rooted several times. And i disturpted device's imei somehow. I tried all methods which r given on xda but they didn't work unfortunately. I I have a last option, gonna leave my device to warranty again but don't know they gonna fix it under warranty or not. What do u suggest me to tell them? I mean, they gonna ask me how that happened but i don't wanna say i flashed firmware with odin cos i guess it ruins my device's warranty.
I need to learn, is that possible to lost imei while doing update with Kies or OTA? Or is it possible to happen with any legal application on an unrooted device? I need an acceptable reason to fix my device under warranty. Does anybody have any suggesion?
Thanks in advance.
I think you better not getting official firmware on other websites. You should use the "Firmware Upgrade And Initialization" in the "Tools" of Samsung KIES 2.5. It is totally original and it will download the latest firmware according to your model and serial number.
I tried using this function on my SHV-E210S and the IMEI was not lost but I don't know if there will be any problem on SHV-E210K.
At the same time, do you know how to make SIP registrations on SHV-E210S/SHV-E210K/SHV-E210L? I need that for putting the phone on LTE network and able to receive calls

It seems that it is a must for you to lose the warranty because the IMEI cannot be lost if the phone is unrooted or coneect to the computer with USB debugging mode. However, how come you receive the warranty as I see your location is not Korea?

Hello guys,
I`ve been watching all this topics for a while cuz I have some problems with my Galaxy S3. I`ll tell you what i did.
All worked fine, had the 4.1.1 official rom + root, then i wanted to go to 4.1.2 so i flashed an UK stock ROM. After that i kept getting the "Sim has been removed" error need restart bla bla.. so i search all around for a fix.. i changed 2 SIM cards and nothing. Then I flashed a Poland version 4.1.2 Stock. That version was better but I encountered the "Call ended" error.. calls would end after 3-4mins or i could not call at all. Then i flashed (and this is when the problem started) Stock Vodafone Spain and got "No network". I must say my IMEI/ SN all are intact.
Then I patched only radio modem from the UK ROM with Odin, but with "PHONE" option (i know i did wrong).. i wanted to change only the modem and it worked cuz i checked with *#1234#.. but from that moment not even one ROM has worked in showing me the network. On About phone says "Network: Unknown". Sometimes it connects to Vodafone but when I try to call says "No network service".
Now my phone is in second service and they can`t make it get a network on. They tryed the neverlock thing but i think was already unblocked.
I tryed rooting and using this Ariza. and were 2 versions there.. I tryed v5 only and didnt worked.
I tried the ##72786# and I get the following message: Connection Problem or invalid MMI code (found somewhere that for this code i need to have Wifi on to work?)
Now i`m thinking to get my phone back and dunno reflash with a good .pit file ? or just reRoot and try v4 Ariza.. I`m really sad, it`s been 5 days and I can`t think on nothing else to do.. I even called Samsung official service and they said to send it to them.
If you have any idea, pls need help. tnx
Check your IMEI is the same as under the battery .
Samsung will reject warranty .

you are right.. IMEI and SN are not the same.. pff what to do now?
Restore your backed up EFS folder.
jje
But i think i backed up the EFS folder with the modified IMEI. What can i do now?
nothing. replace the motherboard
SOLVED!
Ok so tnx to JJEgan i checked all the IMEI numbers and only 2 of them were modified. Thing is before I pached the v5 Ariza, I did a EFS backup with that program. That backup img saved my phone.
Firstly I got my phone back from service with 4.2.1 official ROM (thats nice, cost me 0 $ ). I rooted with CF-Auto and used Ariza patch (v4). But my imei was still wrong so after that I used EFS_Backup_Restore_new_ADB.rar to restore my IMEI/SN with the old EFS backup then I used another programEFS Professional v2.0. I checked the option to repair No network and clicked Restore. After that I restarted my phone and I got the messages from provider with APN settings and so on.
Thank you for the help :good:
worked till first restart... now No network again, I`m not a samsung/android fan anymore..
Hey Guys;
A month ago my phone died on me. After a 1 month hassle of the company trying to dodge doing repair the phone on the warranty, they finally gave up.
They replaced the motherboard and when I got it, it gave me zero bars and no network. I took it back and they returned back with a different rom but it was working. The first was some samsung s3 in arabic version rom. The second was a chinese samsung s3 rom. Since I couldn't get arabic keyboard I decided to flash super nexus rom but now I have zero bars and no network showing.
The hardware specs are in the attachments.
Any idea how to fix it?

IMEI correct
Modem correct
CSC correct ??

Imei: unknown
Imei sv: unknown
Baseband: unknown
Can't find PDA, CSC and modem?
Looking at different posts. Tried Ariza patch didn't work. Am assuming I only need to set the imei to get a network. But what am I to set it to?

You cannot set an IMEI .
You either have a backed up EFS folder you can restore or its a service center repair .
Can't find PDA, CSC and modem? either you are clueless or its more than just IMEI is a problem .
Suggest you flash a stock rom for your area via odin from sammobile.com .
Fails then its a service centre .

I am a bit clueless, nut when I had the S3 before it died and had its motherboard replaced. I would press *#1234# to get the pda and modem and csc or you can get them in the about area. But now with the super nexus rom if i press the code it gives " no mobile network" and it does not show in the about area.
I didn't back up the EFS. This problem was present as I said before when I got it back from the in the service center they had a rooted middle east stock rom and it showed no service, they took it back, I thought the reason was loose wiring. And when I got it back it had a rooted Chinese stock rom which was able to connect to the network. The previous Original motherboard had an unrooted African stock rom, they also cheated me by giving me a 16gb motherboard instead of 32gb.
Tried to flash chinese stock rom via odin and got fail. now it will only go to download mode anything less it gives a yellow triangle.
You need a service centre but you have no warranty .

First Flashed Samsung i9300 stock rom 4.0.4 from http://samsung-s3.com/restoring-sto...ware-build-xxalf2-samsung-galaxy-s3-gt-i9300/ (I had 4.0.4 when I bought the phone.)
root the device via Framaroot 1.4.1. apk (http://forum.xda-developers.com/showthread.php?t=2130276)
Installed busybox via busyboxinstaller.apk in google play and installed busybox
last installed ARIZAPatch.apk can be found in xda developers forum and make sure you are connected to the wifi and press the V[0,5] button. Your device will reboot and there will be light.
My phone developed the 'not connected to network' problem which I'm suspecting is down to the IMEI on the software (004999010640000) not matching that on the back of the handset. I've seen the solution in the FAQ but that seems to be for rooted phones. My device is completly stock. Is there an alternative method or do I have to root my phone to get it to function again?
