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.

ACTUALLY.,

then it show errror "rooting failed"
then i came home back and rooted it myself and then gone to him again and he clicked in repair imei and it was done.
so i tell u orignal steps , what i done.
can u afford 100$ to buy that kit?
if you buy the kit, then no need to go to samsung custumer care, u can do it in your home anytime n everytime
my galaxy s2 is GT-I9100. i saw a jellybean update is on kies so i did the update. However after i did the 4.2.1 update, i found out my CSC was changed! before the jellybean update, it was TGY(HongKong) after the updates, it changed to XSP(Singapore)...WTF.............
Also i cannot change the CSC anymore. i tried using CSC select to change my CSC, but it says "com.android.Precnfig not found on your device. Manual mode..." not only in phone, Kies also says my device is unable to do S/W upgrade or something.
BTW i haven't done any rooting. i don't know why after i did the jellybean update, it shows these kinds of problems.
please give me some solution or any feedback!
re-flash.
Sent from the little guy
changing csc code in jellybean requires root access.
i rooted and tried csc select but there is no csc to select from.
anybody know why?
Did you solve this problem?
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..
I used my galaxy mega 2 on AT&T's network for about 4 months without any problems until I decide to root it with either Kingoroot or Kingroot and since then i've been network blocked because it changed my IMEI. I want to change it back to what the sticker under the battery says but have had no luck. So far i've tried flashing it using odin and the z3samsung tool. It was 4.4.4 but now it's 5.1.1 KitKat because I can't try to downgrade because the "repair" firmware 4.4.4 always fails. The bad IMEI 350050500009692 i was told that this imei was a default when your imei gets erased by some mobile tool pro via email. I won't publish the good/true imei that's on the sticker. Baseband G750AUCU3B0H4 , Build number LMY47X. G750AUCU3BOH4. Also I get an error when using the z3tool to write NV data, it says "security damaged". Being the bright person I am I didn't back up anything prior to the first attempt but all I need is the IMEI restored everything else seems to work fine. I'm stumped and need help.
Thanks to all or anyone
ME TOO ON SAME BOAT , pLEASE ASSIST ME ON THIS ISSUE
[/HIDE][/STRIKE]Hi All ,,,
Last week i bought a used phone galaxy S7 G930FD(D is refering to duos i quess). when i dialed *#06# the first IMEI was okay but the second one was nulled, i never thought that is a problem before buying the phone.
The problem started when i flashed super su root through recovery, device rooted successfully but the phone could not connect to my carrier(634 01) network not available, i searched the web and i found this solution https://forum.xda-developers.com/s7-edge/how-to/guide-how-to-fix-check-drk-imei-issues-t3379516
I downloaded the files as mentioned in the post, when i got to flashing the combination file with odin, i booted the phone into download mode only to find out the G930S written on the top left of the screen as the product name, but in settings>about device the phone name was G930FD . Now i think that my phone is actually G930S and the guy who used the phone before me tried to make it dual sim by installing G930FD firmware, and the brick came when i flashed G930FD super su root on G930S device ? if my device is indeed G930S can i use G930FD combination file and firmware to fix the problem as mentioned in the post https://forum.xda-developers.com/s7-edge/how-to/guide-how-to-fix-check-drk-imei-issues-t3379516 ?? or i misunderstood something ?
HOW can i SOLVE this ???? and thanks in advance.
Edit: I found a solution, see reply below.
SOLUTION:
Finally i solved it!! know i can say that i have a phone not just a smart device.
I did a little reasersh until i found this Great software: Samsung Pro Z3X Tool without box at this site: https://www.gadgetsdr.com/2018/06/download-z3x-29-5-samsung-tool-pro/
It has a lot of features, i tried the Patch Cirtificate(Network repair) option and it did the trick ! wow im so delighted:laugh:, but the thing is it didn't work when i set the model to G930FD but when i made it G930S it worked! this tool even has a dual sim setting so you can make your phone dual sim easily thanks to Z3X Team.
