hi ,
im new here and that's my first time .
I have galaxy s3 i9300
recently im facing a big problem that accuring suddenly -
suddenly the phone isn't getting phone calls and I cant make a phone calls .
in other words , someone who try to call me , is getting the "responding massage" .
when im looking inside the phone at the settings , I see that the network isn't connected , and therefore I need to search for my network bymyself . sometimes it works , and sometimes not .
I tried to change the sim card to a new one and even to another sim card and still the problem is continues.
I tried to Restore factory settings , but no use .
I have to say that at the time that the phone is losing connection with the world , I can see on the right top of the phone that I have "Absorption" .
also at that time im getting Wi-Fi .
I have 4.3 android
the imei is normally - 353976.....
I don't no what to do , please advice me
Type in dialer *#0011# an check info in IMEI CERT line. If it is FAIL info than probably you lost your serial number and it need to be repaired via box in any service center. It's due to efs corruption.
If you have efs backup you should restore it.
If there is PASS info than it is hardware fault, ie . antenna wire or SIM port need to be replaced or reconnected properly. It's hard to say.
From the software side you can try to change 3g to 2g or vice versa to check signal strength. Turning on airplane mode, restarting and turning off could also help. Checking APN settings is also good place to search for the reason.

hi SirKunon ,
thanks for your advice , ive done what you've told me and I get - pass !
now what? to change the antenna although I have wifi anytime ? or this antenna is not related to the wifi?
to change the sim-port?
how do I know that I have to replace these two items - antenna+sim port?
what about the "apn" ?
what about flashing new rom or new karnell?
waiting for your advice
Od course you should primary search for software issues and restoration methods before taking screwdriver
If factory reset doesn't help then flashing stock rom should be a next reasonable step. Take out your SIM card and SD card before flashing. SIM card will copy it's APN settings to new flashed firmware later.
BTW you shouldn't repartition your phone in this case. It is not necessary. Just flash newest stock which corresponding with your country code.

what kind of "software issues and restoration methods" do you recommand me?
what kind of rom (with "more local 2" language support) yoou recommand?
how do i know that i have a root ?
First make a factory reset via system settings or recovery mode.
Second you can try Kies software initialization and restore option to write original firmware hardcoded with your device serial number.
Third upgrade firmware via Kies to newest version.
You can bypass second and third step if you prefer using Odin but if you're asking about root than I think you should use Kies to avoid problems. You don't have yet knowledge to use unofficial tools even if they are more effective.
But Odin don't have access to Samsung's device info database and can't automatically restore your factory firmware. Kies allows that by provided tool of phone's initialization.
Not many users know that option even less are using it but it is good solution for newbies.
If your phone was equipped originaly with Android lower than 4.2 in example 4.1.2 you will not be able to use your efs folder converted already do version 2. But don't worry. Just upgrade to 4.3 via Kies and everything should work flawlessly.

ok ,
after 3 days of observing I can say that the problem is - the network isn't Available , especially at closing places like my home , my office .
so , what you suggest - replacing the antenna+sim port ? ...they cost a few dollars ...
or ,
replacing to a new rom , although its the original rom of Samsung (4.3) and im very satisfied from him for a long long time - almost two years without any problem !!!
or ,
replacing the "radio"/modem/karnel ??? ...im not so expert so I don't know about it
I really need your advice before throwing my s3 to the ...
I understand that everything worked flawlessly in this configuration and suddenly problems occur, right? If you didn't modify your software than problem may be in hardware.
Install app called Network Signal Info and check radio power of BTS towers and received signal. Try both 2g and 3g modes and compare results.
Replacing antenna is very easy, here you go tutorial how to do this:

thnx , but you what is so funny ? My two brothers has the same phone company and we both has the same micro-sim , they have htc and lg , and i have s3 , so , they dont have any problem as i do .
So , what do you think? To replace the antena?
...by the way , do we have any tool to cheak the current antena?
is there any connection between the wi fi (that I have perfect) and the cellular signal (that is dissapeer suddenly) ? are they working on the same antene?
I wrote above about the tool you can check that. Can't diagnose your problem without any data about signal strength and such.
Don't know is it badly positioned middle frame, disconnected or faulty antenna wire, faulty chip on the motherboard or flooded circuits. I don't have your phone in my hands to check all of this. You need to do it. I can only guess because there is plenty of things which can affect your problem.
Software, hardware, cell operator... You need to eliminate them by checking one by one starting from the essential which is software configuration, wipes, flashing new system. Than, if nothing else help, you can check your hardware.
Replace battery for new one. Unscrew middle and middle-top frames, check flood markers, clean connectors, reconnect them. If this will not help than you can try to replace simcard Bay, antenna wire. If this fail you will need to reflow GSM chip in sevice center.

ok here are the results -
when I cheaked outside my home it showed - -83 dbm 11 asu
when I cheaked inside my home , the signal was weak and it showed - -105 dbm 7 asu
I've got - 71dBm*21ASU inside my apartment.
Something is really wrong with your antenna or modem.
Install Getting app from Playstore and check your right matches modem version. If not use download and install rid option within this app.
Also compare those results with another phone.

how can I find the name of my recent modem?
Sorry, stupid android autocorrect. I meant GETRIL app.
Type *#1234# or check in settings about device info for current modem version.

Hi.
I have a big problem with my G2, and have tried many things.
It all started 2 weeks ago. I lost connection to my network.
I tried many things, and ended up giving it to a repair shop, in China, as I was there shortly. They put a new firmware into the phone, and a chinese SIM card worked.
I found an english version of the firmware, and asked them to update with that version, No problem. Everything worked well...but when I arrived back to Denmark, same problem. Not registered on the network.
Now I have tried many things, as Kies could not recognize the firmware version. I burned a 2.35 version into the phone with Odin, and Kies regocnized the version, and now updated to 4.03. Great, but ... I have the same problem. APN settings acc to my network provider. Oister 3 in Denmark.
I really have no idea what to do anymore. And I cant send it in for repair, as the flash counter says 10 times.
Is ther someone here, with a very deep knowledge in Logs etc, as I can send Logs if I am explained what to do.
The short time the phone worked, did I really love it.
And also the chinese SIM can not connect from Denmark.
I would prefer all Logs etc in private email, but if we solve it, I will poste solutions and results here.
Best of regrads
Morten
As for the counter, install and run triangleaway - it can be found in the SGSII section of XDA.
Check that the sim card works (try it on another phone) and borrow another sim card (on the same network). It is amazing how many problems like this are due to a damaged sim card or just not connecting correctly. I had a friend who took the sim card out to flash their Samsung Galaxy 3 and put in the sim card wrongly and couldn't make a call.
Can you copy your contacts to or create one in the sim card?
I doubt that it is a problem with the EFS folder, ie no IMEI number because it was fixed with a china sim, but it may be. Is the IMEI number you get from dialing *#06# 004999010640000 or different from the label under the battery? If so then you have a EFS folder problem. There is an app that may fix it - it requires root - * HERE *
Mobile network
Hi
Thanks for the reply.
A:
I can make, copy, edit etc contact directly at the simcard in the phone, and also copy, edit etc from Kies to the Sim card. And yes. It is the simcard I can do those things at. Double checked that it was somcard and not the phone memory
B:
Double checked the IMEI number again.
Label phone same as *#06#
Further information:
In the first day, I tried many many things to get the phone working.
I searched the internet a lot, and I found some kind of help. Like with IMEI check, I should type a code like *#xxxx# or *xxxx* Stupid as I was, I did not write down the code, and also did not safe the page on the internet, so I have no idea what code I wrote. I am sure it was something regarding Mobile network or CSC.
Reg Triangle away.
My phone is no longer rooted, as I try to have it in original mode, so its ready to send to repair, if needed. Triangleaway needs the phone to be routed, right ?
And will that not require an unsafe kernel ?
After resetting, then I suppose I need to install an original kernel again, and will that not make the counter go to 1 ?
Any other ideas ?
Regards
Morten
can you be little clear....
no network or no data (internet) on your current network
1: do you have a locked phone or unlocked. [carrier locked when new]
2: no network will be no signals at all, no phone call....
3: no data will be you cant browse, send receve emails
4: counter can be fixed easy as now your on ics
Hi,
I got the same problem but different scenario

1. my phone is unlocked(international).
2. signal show full, but no phone call
3. I don't use data, but wifi, and no problem with wifi.
Well, this : not registered on network only happen if phone idle for more than 3hrs, meaning phone just work normally if I don't let it idle for long time. This very frustrating as every morning after wake up I have to switch between airplane mode for phone working again.
Greatly appreciated for your help
Thanks in advance
P/s: currently on Slim rom(cm9). But have tried almost all custom rom found in xda, problem still exist. Even try to change CSC to my current country( Thailand) on stock DL7( included Thailand region), no luck. APN setting also change to default network provider.
Mobile network problem
Hi.
Please see my answers below
1: do you have a locked phone or unlocked. [carrier locked when new]
The phone worked before, and was not locked, but as I send a command to the phone, could I have locked it ? How can I check that ? And it does not give me any warning when I start the phone up.
When I try to make a call, it right away says: Dialling ...Call ended.
2: no network will be no signals at all, no phone call....
No mobile network. It is ONLY a problem with phone calls and reciving calls.
I have plenty of signal
3: no data will be you cant browse, send receve emails
Data is right now not working, WiFi works.
I cant get correct APN settings, as my provider sends this as system configuration to the phone, but cant recive it.
3A: My provided is named 3 Oister, and normally this provider is listed under Network operators. On this phone it is NOT listed. 3 Oister is using network of 3, and only network of 3 is listed.
If I pull down the menu from the topbar on the phone, it actually says 3 Oister, but 3 Oister is not listed under Network Operators.
On my other SG2, 3 Oister is listed in Topbar and under Network Operators.
I bought a new SG2 as well, and we are 2 persons using SG2 here.
4: counter can be fixed easy as now your on ics
How ? Can I do that without rooting and install different firmware ?
I do run ICS ver 4.03, updated by Kies.
In worst case, I will send the phone in for repair, but for sure, needs the counter reset.
Regards
Morten
Put a new firmware in the phone then probably wrong modem and CSC for your location .
Chinese sim unlikely to work 4000 miles away but that is easy to swap sim .
Rom counter for ICS use the search tool for the relevant post .

Hi
Please find answers below:
Put a new firmware in the phone then probably wrong modem and CSC for your location .
As my counter says 10, you can see, I have tried this several times, and its also written in my first post.
Please send the code for check of CSC and changing CSC. As I remember it is set to be NEE.
Chinese sim unlikely to work 4000 miles away but that is easy to swap sim .
Chinese SIM works all over the world, as long as Roaming is allowed. And it works in the other phone. Now I have the Denmark SIM in, and same problem. Yes, I did close down the phone, changed SIM and started the phone again. Exactly SAME problem.
Rom counter for ICS use the search tool for the relevant post .
Would be nice to have the info written here instead.

1: forget all your idea's do exact as i say
2: remove your sdcard
3: using cwm format system, cache, data, sdcard [system is a must]
4: remove battery / insert back goto download mode
5: flash the ROM you downloded using odin, after restart dont do any restores
6: wait for few minutes now dial this *2767*3855# [important]
dont restore any backups including titanium stuff.
if your phone works now put your sdcard back and do whatever now you want.

Mobile network problem
Hi again
Followed the guide very detailed
3: using cwm format system, cache, data, sdcard [system is a must]
Wiped all data in System and also Wiped Cache, using:
Root the Samsung Galaxy S2 GT-I9100 running XXLPQ firmware and install ClockworkMod Recovery: CF-Root-SGS2_XX_XEO_LPQ-v5.3-CWM5.tar
Done with Super User Granted.
4: remove battery / insert back goto download mode
Done
5: flash the ROM you downloded using odin, after restart dont do any restores
Flashed with Odin 1.85 in PDA: I9100XXLPQ_I9100HTDLP3_I9100NELP2_HOME.tar.md5
6: wait for few minutes now dial this *2767*3855# [important]
Done. Phone shows Factory Reset in big letters
dont restore any backups including titanium stuff.
Nothing restored.
Booted up, and automatic installed APK's
Same problem.
Only difference is that now the counter says 11 counts
But thanks for a detailed and well told possibility.
As I see it, the problem is connected to the standard the phone connects to the Mobile grid. As I told earlier, I made a stupid thing. I send a command with *#xxxx* in the phone, and I cant remember what code, and I did not save the page on the internet. I really think the problem is about a standard. That the phone is setup to a standard that the 3G net is not using in Denmark.
I can dump logs etc, if anyone can help. But I need to know how.
Regards
Morten
buddy your problem was.... network right? is it working now?
forget counter it will be fixed....later using triangle away with ics bootloader
---------- Post added at 12:06 AM ---------- Previous post was at 12:01 AM ----------
if your phone now works fine with calls send and recieve, manually add the apn to get 3G.
Mobile network problem
Hi
Nope. Did not solve the problem.
Just ran Triangle away, and moved the Firmware: I9100XXLPQ_I9100HTDLP3_I9100NELP2_HOME.tar.md5 to the SD card.
Will try now to install it by CWM
And then I give up. Will try to send it for repair ..... really a shame, as I really would have liked to solve it here
Cheers

Mobile network problem
Hi Buddy
It finds a lot of Networks, but cant connect to any of them
3 networks with 3G and 4 with 2 G
But not the Mobile network I need to connect to> Oister 3
My other SG2 finds that network without any problem
Cheers
Morten
I had the same problem too. At first I tought it was a rom issue, but it wasn't actually. I turned my phone off and removed and placed back my sim card and it worked.
Mobile network problem
Finished programming original firmware using CMW as source for Odin, after counter was reset to 0, and the pnone status is the same as before, but counter is 0.
So will try to send it in for repair.
Thanks to u all.
And SIM card has been removed several times, even tried with a different.
No luck at all
Cheers, and thanks again
Morten
Did you ever get to the bottom of this?
I've been using my phone in Brazil and now i'm in the UK, it's doing exactly as you describe.

How would you go about checking these?

Compare the IMEI that displays when you type *#06# to the IMEI printed on the label under your battery. They should be the same.
For your own sake, do NOT post what the IMEI under the battery actually is, whether it's the same as what's displayed when you dial *#06# or not.
As for checking IMEI blocking by the carrier, that should be obvious. Call your carrier.
Hi All,
I have accidentially bought Galaxy S3 GT-i9300 in China. Device came with Hong Kong 4.0.4 firmware. Unfortunatelly i could not fully test it because i didn`t have a micro-sim. It is international version called I9300GSMH.
I returned home, made a backup of EFS with EFS Pro and flashed 4.1.2 Poland into my new toy.
After that i immediately got several problems:
1) IMEI is OK and legal, but SN = 00000000000. That means no network and no phone calls. Fixed quickly with "special modem", but not sure if it was the best way.
Is it possible to repair SN if i know it? Does it make any sense by the way?
2) GPS is not working at all. GPS Tool doesn`t see any satellite. Neither GPS no Glonass.
Have no idea how to fix it and why this sh,,t happened.
3) Wi-Fi range = 30 cm. My router is Dlink DIR655. Other Samsung devices work with it up to 15 meters around. This one - 30cm. Tried to change settings, apply fix - no result. My S3 can see all wireless networks around, even located on the different floor of the building... but it can`t connect to any of them with "passwor wrong" message. Put it right on the router and problem disappers. WTF???
My S3 came from Hong Kong, but it doesn`t accept China/HK firmwares. Odin stops on flashing the modem stage. Actually, for some reason, it can`t flash China/HK modems. My S3 accepts any of european FW/Modem, but not chinese, where it actually came from.
Now some surgery. /EFS and /Factory folders are different (how could that be?) Files NV_data.bin and NV_data.md5 are different in those folders. Actually approx 300 bytes are different.
NV_data.bin and .NV_data.bak are totally different and they have different dates of creation.
That is it. Have no idea what to do with this phone. It works as a phone with the patched modem, but no WIFI, no GPS, etc.
I will appreciate any help on this case.
Thank you in advance.

Thanks, but it is already done. My S3 doesn`t work with GSM network without Ariza patch. "Special modem" i meant Ariza patch for modem. That is the only way i know to make SN=00000000000 device work with GSM.
Any ideas why i`m having GPS and Wi-Fi problems? May be HongKong phone has slightly different hardware which is not 100% compatible with European firmwares?
Sounds like a convincing looking fake or a store demo unit etc.
Nothing is going to help, if it was a workable fake your going to need the custom firmware, the criminals used originally to build it.
Can you post a screen shot of the system info and pics of the actual phone?
Personally I'd just take it to a mobile repair shop to get it looked at and to get a proper answer.

I don`t think it is fake because system information looks like genuine samsung except sn=00000000000. also i can upload samsung firmware to it and it works except GPS and Wi-Fi. Under the battery there is a label containing Model = GT-I9300, real IMEI and SN.
Another question is modem. Telephone came from HK or China. I can flash it with HK firmware to return it to original state, but modem remains XX - europe. When i flash only chinese modem Odin fails with "bootloader blocked modem update" or something like that.

Why do you think it is fake? Fake phone has different firmware and not compatible with Samsung.
I have checked deviceinfo as well. It is genuine Samsung...
Can someone share deviceinfo from the International GT-i9300 ? I want to compare, may be some IC chips are different and i am simply using incompatible firmware...

Hi All,
I have accidentially bought Galaxy S3 GT-i9300 in China. Device came with Hong Kong 4.0.4 firmware. Unfortunatelly i could not fully test it because i didn`t have a micro-sim. It is international version called I9300GSMH.
I returned home, made a backup of EFS with EFS Pro and flashed 4.1.2 Poland into my new toy.
After that i immediately got several problems:
1) IMEI is OK and legal, but SN = 00000000000. That means no network and no phone calls. Fixed quickly with "special modem", but not sure if it was the best way.
Is it possible to repair SN if i know it? Does it make any sense by the way?
2) GPS is not working at all. GPS Tool doesn`t see any satellite. Neither GPS no Glonass.
Have no idea how to fix it and why this sh,,t happened.
3) Wi-Fi range = 30 cm. My router is Dlink DIR655. Other Samsung devices work with it up to 15 meters around. This one - 30cm. Tried to change settings, apply fix - no result. My S3 can see all wireless networks around, even located on the different floor of the building... but it can`t connect to any of them with "passwor wrong" message. Put it right on the router and problem disappers. WTF???
My S3 came from Hong Kong, but it doesn`t accept China/HK firmwares. Odin stops on flashing the modem stage. Actually, for some reason, it can`t flash China/HK modems. My S3 accepts any of european FW/Modem, but not chinese, where it actually came from.
Now some surgery. /EFS and /Factory folders are different (how could that be?) Files NV_data.bin and NV_data.md5 are different in those folders. Actually approx 300 bytes are different.
NV_data.bin and .NV_data.bak are totally different and they have different dates of creation.
That is it. Have no idea what to do with this phone. It works as a phone with the patched modem, but no WIFI, no GPS, etc.
I will appreciate any help on this case.
Thank you in advance.

Exactly same situation in Argentina.
I bought a SGS3 and after full charge battery and backup EFS I flash the Poland 4.1.2. After that i can´t connect to GSM network and my serial numer is 00000000000
Is not a fake. I bought from a recognized operator.
Then I flash an ICS 4.0.4 ARO (ARO = Samsung official roms for Argentina)
Now I looking for the Ariza solution, but I fear to have the same problems descripted here, cause I have the same facts.
So ¿Any questions to this post answers?
Thanks people, for that who live away from big cities is impossible go to a technical service.
Update. I`ve also got i9100 aka Galaxy S2. After official (no grey market, no sim-unlocks, no root, no odin, etc) update via Kies it shows same SN=00000000000, but everything is OK. GSM, 3G, WiFi, Bt, Gps - all parts work as they should work without any problems or applying any patches!!! That means problem is not in SN=00000000000. This zero SN is probably just a sign of the different problem.
same problem

Thanks, but it is already done. My S3 doesn`t work with GSM network without Ariza patch. "Special modem" i meant Ariza patch for modem. That is the only way i know to make SN=00000000000 device work with GSM.
Any ideas why i`m having GPS and Wi-Fi problems? May be HongKong phone has slightly different hardware which is not 100% compatible with European firmwares?

No IMEI = return to seller possible stolen phone . Take to service centre .
Modem does not fix IMEI .
IMEI restore is only by restoring your backed up EFS folder .

If your phone has only empty/broken IMEI. You may send it to any service center. It is very easy to reprogram EFS and repair IMEI if you have original IMEI on the phone label.
In my case nothing worked but IMEI was correct and here is step by step instruction )
Step 1. Find working 2nd hand 9300 motherboard ($130 in my country).
Step 2. Replace motherboard.
Step 3. Ta-da.
hi
need some help on my galaxy S4 :crying:
model: SAMSUNG-SGH-I337
android version: 4.2.2
1. why i got 0 (zero) on my IMEI ? (I can make and receive calls)
2. why my phone perform reset (No predefined times) - I think when is in effort - But not sure about it
3. How do I know the phone is not fake ? (I bought it two days ago)
thanks in advance
What carrier you on ?
Just guessing but if its gsm phone then its all maybe on your sim.
China is building phones can do both cdma and gsm at same time dual sim i think
That's probably the reason why they sold it.
They ruined it ur phone.
Solve:
Reinstall stock firmware through KIES.
let me know if it works.
(I had the same)
I think flashing modem files are pretty enough
Sent from my C6902 using XDA Premium 4 mobile app
several steps and a lot of reading requires

You need efs pro if you had done a backup of several qualcomm radio modem earlier. Read more. http://forum.xda-developers.com/gal...ol-updated-08-12-13-efs-professional-t1308546
Then you need QPST software, also it is from qualcomm. It is a diagnostic tool but you have to activate the com-port within your phone with some tricks or usean apk called phoneutils.apk.
If you search you'll find. Me to had corrupt imei when I tried som things inside my phone, for example I deleted the NV-build (the golden build) and thats I it happens. I tried to unlock it. In this forum XDA, it is not aloud to tell you how.
In short you have to be
rooted,
usb-debugging enabled,
installed free version of busybox.apk.
installed software on your pc (efs pro and qpst)
and phone-mode in usb-modem-diagnostic. http://forum.xda-developers.com/showthread.php?t=1626638&page=11
You probably have lte so it is qualcomm. But don't trust me, search by your self. Do you have the original backup or the original imei-number left in the box you bought?
I made a restore from my friends backup and putted back the imei when the com-port was connected, With Efs-Pro manager in the link I wrote.
Good luck!
Dont forget to thank me if I helped a little, I haven't checked if you have qualcomm (4g) or exynos chipset (SoC) systemOnChip
hi guys i bought an samsung galaxy s II I9100 not new but still in a good status and he is runing very good when i bought it he had the an stock android 4.0.4 informations in attachement when i want to update to the 4.1.2 version he says that this is the last update for the phone so i downlaoded an 4.1.2 firmware from samfirmware i update via odin without problems but when i verify the IMEI isn't the same at the back of the phone and another thing on the back of the phone there is NFC under the camera but can't find't in options :crying:
No Help
1) I9100 = no NFC. If that phone has NFC capabilities, it's not an I9100. It will more than likely be an I9100P.
2) If the IMEI (in phone settings) has changed to '0049...' (Do not post your actual IMEI here), you might be in a bit of trouble. If the phone is an I9100P, download I9100P firmware from Samfirmware & flash that; hopefully the IMEI will come back. If the IMEI doesn't return, flash another firmware, and another and so on.
If it is an I9100 & you're merely confused about the NFC thing, download a bunch of I9100 firmwares & flash.
If after flashing a bunch of firmwares you still have the generic IMEI, try one/more of the many 'guides' on here which claim to be able to recover your IMEI without an EFS backup (no idea if any of them work or not).
If you still can't get your IMEI back, take it to a local mobile repair shop; many have equipment which can write the IMEI back to the device fairly cheaply.
Edit - Use a descriptive thread title in future - 'Help me please' is more than likely the reason you've been sitting for 18 hrs waiting for help, many people won't even look at your thread without a title which gives some idea of whatever problem you're facing/question you have.

thanks for your help what if my phone is i9100 and i have flashed an i9100p firmware what problems i'll have?
Probably none. The firmware is identical except for the NFC bits, as the I9100 doesn't have the hardware, that part of the firmware doesn't do anything. Given the rom will likely be for a completely different carrier, the modem in the rom might not be ideal for your particular carrier, and you might have connectivity issues, or you might not. But that's moot given you have the generic IMEI, you should have pretty much zero connectivity anyway (you'll be able to see the network but not use it).
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...
