Hi everyone,
I come to you as I am a noob as far as twinkering with my gt i9300 goes and I think I messed it up big time.
Here is what I did :
I had android 4.2.1 on my gt i9300, the stock rom from sfr (french career).
I network unlocked it using my career official unlock code, which worked great. It recognized my japanese career sim very well (i am in japan now).
Then I got greedy and wanted to update my android version so I downloaded a 4.4 android rom from I don't remember well, and a cwm manager.
The network unlock worked fine at first but after a restart it did not work anymore. It asked me for a network unlock pin.
I thought it was asking for a sim pin at first, which my sim did not have as I hadn't set one. I got mad trying sim pin code and gave up. Had I given it the network unlock code instead of possible sim pin code it might have worked but I will never know.
Then I tried to solve the problem installing android 5.1 cyanogen version but I had the same problem except this time I understood it was asking for the network unlock code. The problem is that when I fed it to him, it did not work, the request was unsuccessful.
So I looked for a solution on internet and found all kind of things:
I read about restoring the efs partition, but i do not have any back up.
I read about installing a stock rom version, change the csc and retry the official network unlock code, but it does not work, whether I restore through Kies (which gives me a vodafone version) or manually (with an sfr version, french vodafone it seems).
I read about installing Galaxy simunlock app after rooting the phone and installing userbox, but it tells me that my locking system is not handled as it is too new.
I upgraded, downgraded, rooted in every possible way but nothing works.
I am running out of solution and I therefore turn to you for help, hoping you will be more creative than me.
I have the official network unlock code, the phone, no back up of any kind and really little hope.
Thank you in advance for any help you could give me !
Have a nice day !
Sadly you didn't make a backup of efs. That should be first thing before playing with customs.
Oh well, I suppose your efs may be screwed up due to entering couple times bad network unlock key.
I suggest go to next corner GSM shop and pay 2400JPY for efs fixing and perm sim unlock. But before that, check your IMEI and serial number are correct. Thay can fix all of this in one step.
You need to do this via box, you can't reprogram that or fix yourself because you did everything that may help and you still have a problem. You can't use any software on efs v2. It will not work.

Thank you for your quick answer !
I will follow your advice and go to a "professional".
However I don't understand how they are able to do what I can't, do they have special softwares or anything ?
I would like to know because I do have the official unlock code.
Also, I would still like to upgrade to android 5.1 cyanogen version, do you think it will be possible after such a modification ?
I should not encounter any risk if I backup the efs beforehand right ?
Thank you again
Service will connect your phone to, so called, box, ie Z3X Box. This is some kind of pc-phone bridge hardware which can alow to decrypt and encrypt efs files, fix IMEI, serial number, flash firmware, IMEI certificate, remove network locks, sim locks etc.
Of course you can backup your efs now but it is corrupted and useful. Backup this partition after repair. Than you will be able to flash anything you want. Even CM12.1,no problem.

Ok I understand better now.
Thank you very much for your answers, they have been really helpful !
Do not let them plug your phone to the box if you want to install 4.4 or 5.0 because if you give them they will replace your imei number with a clon imei number and you will stuck with max 4.3 and you need to install a patched modem and kernel every time you format your phone... tell them to try to fix without replacing your imei number first. Replacing the imei number should be the last thing to do...
Why do you think they will clone his phone's IMEI? It's even illegal.
If someone doesn't know how to use box than he should not work in GSM service.
You can rewrite original IMEI and serial number without cloning anything.
An probably IMEI is fine, it's network lock problem.

Most repair shops dont care its legal or not. Also most costumers dont know this kind of things and as long as phone is working its okay for them. Mine is just a warning to make him look like he knows this things so repairman doesnt do something with no going back...

Hi guys.
Here`s my problem.
My brother bought an international variant of the Galasy S3, i93000 a couple of days ago from an online auction website. To make the story short, after trying to figure out why the device isn`t connecting to ny carrier, I found that it had a generic IMEI. Go figure, got the same problem earlier this year with an SII.
The previous owner flashed it a few times, as it came with a variant of Jelly Bean, XXDLH8 I believe.
Flashed a stock open europe ICS (XXBLG8) and rooted it but still have the generic IMEI.
I found some threads online on how to rewrite your IMEI code back, since it is written on the back of the phone and on the box, but it only applies to the Verizon version of the S3. I need to access *#7284# and select something that isn`t there on my device. And using a piece of software called NV reader/writer, you edit your IMEI directyly on your phone. It has to be put in the correct form, but it is possible.
My question is, how can we edit our IMEI code on the international version of the SIII ? Don`t get me wrong, I don`t want to modify it all the time, just trying to get it back to how it was.
Sending back to waranty isn`t an option as the previous owner bought it from another country, and also he now refuses to answer my calls.
I`ll have to mention that the device isn`t stolen, it has the Samsung generic IMEI, which wouldn`t be a problem ig it wasn`t blocked by my carrier.
I know have a really expensive device that isn`t more than an iPod. My brither doesn`t even want to see it anymore.
It has to be a way we can restore our IMEI via nv_data.bin and a HEX editor.
You can not be sure that this phone wasn't stolen. Previous user could wipe or modify efs partition to not be tracked by IMEI. Or he just broke efs while flasing and sold the phone because he couldn't fix it.
The warranty is valid throughout the whole European Union, not only in country where the phone was purchased. But you did not write where the phone was purchased nor where you live.
You can serch your internal sd card, maybe there is a backup of efs folder. If not, you can try to use some tools to restore correct IMEI to nv_data.bin from .nv_data.bak (EFS Pro or similar).
You could also try this manual solution:

Hi there.
Yes, I can be sure that the phone isn`t stolen as it has all the necessary paperwork to prove it.
Regarding your suggested fixes, I`ve already tried the first one, restoring from the .bak files with no success.
Also I read the second one earlier and I can`r apply it as my nv_data.bin file doesn`t have even have the lines mentioned in the tutorial. It says that I have to edit line 0188008, but my files goes from 0188001 straight to 0188014.
I`ve found a tutorial over at http://forum.gsmhosting.com/vbb/f606/tutorial-galaxy-s3-backup-restore-imei-without-root-1513909/ (sorry for the external link if they aren`t permitted) but it applies to the Verizon version (I believe) with the Qualcomm cpu. When I dial *#7284# on my device I only have the 2 sections with 2 options each. UART where I can select Modem or PDA, and USB with the same two option. Because of this, the app NV reader/writer can`t access my device.
Hello everyone,
I have Samsung Galaxy S2 international GT-I9100. It fall into water. After that everything working fine excerpt IMEI null/null, Baseband Unknown, No SIM Card Detected. I exhibited it and dryed for a month. When I compiled it up again, same problem.
After that I decided to change the moatherboard. I bought new one, change it, turn phone on and same problem!! After that I install new ROM via Odin. And the problem still exist! How this is possible?? Oh and I want to mention that I can't access service mode. When I try to access it service mode is opened but menu is blank!
What you think the problem is?? Maybe smaller motherboard, because the small one at the bottom of the phone I didn't change. I am very desperate after so many tries so please help me.
Thanks a lot
anyone???

most probably your efs folder is corrupt or some hardware faulty. Do you have any sort of efs backup with you ?
If you have no backup, you're probably boned. Download as many stock roms as you can & start flashing. If that doesn't work, take it to a local mobile repair shop; many have equipment which can re-write the IMEI to the device fairly cheaply.
Thanks for answers, no I didn't make any backup for efs, so today I will start flashing all available ROMs for my country if this will not work I will take it to the service.
Hi!!:
After reading and reading and trying every method i found on the internet, i still have not succeded with my problem which is this:
I tryed to flash an stock 4.3 to my free s3 movistar chile, but when it rebooted and after i wrote the pin code, it asks me for an unblock sim code
It presented signal but uknown network. I got back to 4.1.2 thinking that it should repair this, but no, it was worst, i got imei null,
After searching and searchingI found a cwm 3 files patch on the internet: one for cleaning kernel, other one to install kernel and the other one to install modem, and with it i got my imei back, (this is when i made efs backup, i know i sould have done long before ) but also the wknown network problem, with the phone asking me for this unblock sim code again.
I used galaxysim unlock to try to repair this, but it showed me that the phone is totally unlocked i think i remember it also showed me the state of csc and it appeared blocked, so i think this is where the problem lies, but i couldnt find any info about this.
when i go to state of the phone i see this
network: uknown
kind of network: umts
service state: out of service
mobile network state: disconnected
imei:3537.... thats ok, fits with the one on the back of the phone
device state: modified
(sorry if my einglish is not very accurate)
So resuming: my imei number is ok, wifi works ok, but even though the phone shows signal, it presents uknown network, and i cant do or receive calls.
i would be very thankful if any of you could help me
Your phone was unlocked using a crack that only worked on 4.1, by updating to 4.3 you've corrupted the efs folder.
You now need to buy an unlocking code and pay for a repair, make sure it works on 4.3 before you accept the phone back.

Thanks a lot for answering!. So, if the phone was cracked in 4.1.1, is there any chance to downgrade to that version, use the corrupt efs backup that i have, just in case i lose the imei, and try to unlock?, or would be too risky?
Not without a backup of the efs before you upgrade, no.
Hi all,
I have a UK GT - i 9300 locked to Orange and i have just been signed up to EE.
EE claim the phone is already unlocked.....it isn't. They failed to provide a SIM unlock code, so i went to a third party (computer shop) to get the code. They provided an unlock code, and an unfreeze code. They don't work. It just says "registration code unsuccessful" or something similar when i try to put it in upon booting up the device. The guy at the shop is now at a loose end and is happy to refund the unlock code fee, but says he cannot unlock the phone.
I have tried the codes that start with #1972.... to enter the hidden menus, i actually had to enter #0011# i think....regardless, that didn't work as under network options (or whatever it was called) i have no option to tell the phone to allow other sims.
I mention all of this because please believe me when i tell you there is not a simple solution to unlocking this phone....i have read pages and pages of forum advice and nothing works.
My very specific question is; can i root this network locked GT i9300 (UK version) which is currently running on 4.3....or not? It is the only possible solution i can see to save this phone from becoming a paperweight.
I can promise you that hours upon hours of research has not got me a sensible, definitive answer to this question.
Thanks guys. Much appreciated.

It doesn't matter if the phone is SIM-unlocked or not when you root it. If i can find a stock ROM for the i9300, or if it is 4.1.1 or 4.1.2 with the old bootloader, it is unlockable for free. http://forum.xda-developers.com/galaxy-s3/help-i9305/guide-sim-unlock-i9305-t3267901 this is the thread, tell me if you want me to find a stock ROM and i will try to make it zip-flashable.

Thank you for your reply.
Unfortunately after nobody responded yesterday i decided to flash the phone back to an Orange UK version of 4.0.4 and see if the Galaxsim unlock program worked from there. It has now given my phone the generic IMEI number 004999010640000 and Galasim is just saying "UNABLE TO READ NV DATA"
I've tried the method of changing the nv data bin files, and it doesn't work.
I have no backup of my original efs folder.
The bottom line here is that i have been going round in circles with this pile of sh1t service from Orange and EE, and codes that don't work for over a month now. I mean no offence by asking this bluntly, but can someone just give me a simple yes or no answer as to whether i need to buy a new phone or not?
It seems everyone has a theory on how to unlock this phone, and none of those theories actually work.
Currently phone is sat on
Android version - 4.0.4,
Product code - GT-I9300RWDORA
Original Product Code - ORA
IMEI NUMBER - 004999010640000/01
Sim Operator - EE(23433)
Registered Operator - @[email protected]
OS version - 4.0.4 (15)
Baseband - i9300BVLE4
Bootloader - I9300XXUGNB5
Patform - exynos4
LOCKED TO ORANGE.
Some simple instructions on how to fix this, or an honest answer as to if it is even possible would be GREATLY appreciated.
Thanks
Hi, i have bought G977N and later came to know that its IMEI is tampered to get registered on the local networks. it was working before i upgraded it to G977NKOU4CTG1, the original firmware was G977NKSU2BSL7. After upgrading it did not register any of the networks. Got it checked from software expert he told me the network patching done with tempered imei was damaged and now there is no way to do it again on new version G977NKOU4CTG1. I tried to flash G977NKSU2BSL and also the factory firmware of android pie but ODIN get stuck at BOOT.img and download screen shows non-supported version. Can any one help to restore my original IMEI and will it work.
The IMEI ( read: International Mobile Equipment Identity ) is a unique numerical identifier ( 14-17 digits ) for every mobile device what helps to differentiate each device from one another. If you take your phone in for repair, they will track it using the IMEI to distinguish it from the other millions of phones, for example.
IMEI basically has nothing to do with phone's local network settings at all. But it may be used to unlock a phone on certain networks.
The IMEI is stored on phone's /EFS partition and/or /EFS folder. If you didn't backup that before flashing you have lost, IMO, unless you still have the box in which the phone was delivered, because there is usually the IMEI printed, too.
I don't have the box of the phone. The seller has tempered the imei to get it registered on the local network. I didn't backup before flashing. Now what to do. How to downgrade to previous firmware. I tried to flash the previous firmware but it stuck in boot.img.
They told me solution is available for U3 binary but no solution is available for U4 binary.
Awaiting for help on this issue.
You should have returned the device. Since the imei has been tampered with you will not get much help here. Imei changing and tampering is illegal in most countries. And it's not discussed on xda

I'm guessing you also bought a tampered IMEI device. Take it to any local market where there are plenty of phone 'software repair' guys. Ask them if they have Chimera or z3x tool. They'll fix your problem for ~800 PKR.
Remember, if you buy such devices, don't flash anything on them. Every time you do, you'll need to go back to the same software guy and pay him to fix your signal issue.
=========================
For other people reading this comment - Yes I understand IMEI tampering is illegal in most countries. The reason people in Pakistan buy these phones is because the government has levied unreasonable duties on all imported devices, without any consideration for the age/condition. For example, a used/refurbished S10 that costs you 250 USD in the US, will have custom charges of about 250 USD applied to it if you want it to work in Pakistan. So basically you pay double.
I have this same issue somtimes the signal comes and somtimes it doesnt.
