After fixing messed up EFS: Flashing custom ROM alters Serial, SIM can't be unlocked - Galaxy S III Q&A, Help & Troubleshooting

Hey folks,
I really badly messed up my EFS recently, with broken IMEI and S/N. It took me a few days of searching, reading and trying before I finally could restore both IMEI and S/N.
Part of the problem was the XXEMG4 EFSv1 to EFSv2 change, and I lost the backup'ed EFSv1 files (of course I did NOT make an EFS Backup when I got my I9300, shame on me).
So now I face another problem that very likely is related to the above story:
I wanted to flash a Cyanogen 10.2 nightly via mobile Odin but it froze, so after 15min with no progress I rebooted to download mode, flashed Phil'z Touch recovery and reflashed Cyanogen after full wiping.
It booted properly and asked for the PIN, but the correct PIN wasn't accepted anymore. There was no "Wrong PIN" or anything, the same SIM unlock screen appered again. "sim/rmei(or rmid? Anything like that starting with R...) locked" was written at the bottom of the screen.
I shut the phone down, removed the SIM card and booted straight into Android.
In the settings I found my serial no being altered, something starting with 4f..., it was also longer that the usual serial. To me it looked like a hex number.
When I reflash the stock image everything's fine... I haven't tried to flash another rom yet, maybe that's still an option?!
Any other ideas save for "take it to a repair shop"? Unfortunately there aren't any around my town...

Previous unlock methods no longer work with efs v2, there is no solution at present other than unlock code from your network provider.

So, I've tried to flash AOKP now, same problem. The full text is "SIM/RUIM card is locked. - emergency calls only".
I'm not certain, but i think this is the default text in the SIM unlock screen.
No matter which digits I enter, when hitting ENTER the PIN field gets cleared. Even with a wrong PIN there's no "Wrong PIN" warning.
The IMEI is still correct, but the S/N has changed, now it is 4df772e33ef0cf19.
I remember similar problems with my Desire HD when flashing an AOSP kernel on a Sense based rom...

[Q]SgsII Mobile Network not avaliable- HELP

I wanted to sell my Galaxy s2, the guy wanted it to be factory reset, with the original firmware.
I have downloaded GT-I9100_XME_I9100XWKF1 firmware, it worked. But I had the "sim locked" symbol in the notification bar, so I wanted to unlock it.
I downloaded CF-Root-SGS2_XW_OJV_KF1-v4.0-CWM4, and rooted the phone.
Downloaded the Galaxy Unlock app from market place, followed steps 1-3. Phone rebooted.
The unlock didn't work, Instead of a sim locked symbol in the notification bar, I got this stop symbol (like in "no smoking" sign). When I try to go to settings->wireless and mobile network->mobile network, I get "Insert Sim Card to access network services" (sim card is insert correctly, i double checked). When I try to make a call, same message "Mobile Network not Avaliable".
I did some search on the forum, one of the guys said that I should check if the IMEI is matching, I dialed *#06# and got the word: "IMEI", no serial, just that.
I tried to go to Unlock Galaxy app and do a restore efs (step 4), i get the message "You don't have efs save in /sdcard/Galaxy_S_Unlock"
I tried the sim card in a different phone, it works. Tried a different sim in galaxy, it doesn't work.
I tried to do a reset of the device from a backup I had from a month ago, it didn't help, same problem.
What can I do?
here.

Thank you for the reply, I have tried the GSII_Repair, just now, I installed busybox on android device, and followed the steps.
Step 1 was succesful, so was 2.
After trying step 3 i got the message : "You dont have .nv_data.bak and his md5 files, canceled"
I did more research and found out that I have network lock. Punching the code *#7465625# confirmed it.
I tried that tutorial: http://forum.xda-developers.com/showthread.php?t=1369474
to fix it, it didnt work because I didn't have the hex adress 181468 nor 18145C in my nv_data.bin
do not use galaxy s2 unlock, try galaxy S unlock, this one is better but with greater risk but never heard anyone had issue with this. Use this then do the GS repair again.
should this one did not work, i suggest you do odin flash of official roms. Tried flashing the rom 3 times, I was able to fix the same problem with my galaxy tab before doing that. goodluck.
THank you ! *FIXED*
I just used the original Samsung Unlock, and I didn't notice that it had a fix built in. Tried it and it worked !

[Q] No service after unlocking SIM (with complications)

Hi. I bought my I9100 in the UK about a year ago, second-hand, locked to Orange. After researching the topic for a bit I rooted the device, installed some custom ROMs and unlocked the phone using the Galaxy S2 SIM Unlock app. It worked and I enjoyed my unlocked phone for the whole year. In that time I changed ROMs couple of times and never had any problems with my SIM being locked.
Until now.
Two weeks ago I thought I wanted to give the new leaked jelly bean rom a try and so I flashed my phone with it. Then, wanting to root it (very foolishly) I thought I knew what I was doing but I essentially soft bricked my phone. I recovered from the soft brick and installed cm10 with 4.1.2 but the phone appeared to be locked to a specific carrier again. I thought that's no problem and tried using the Galaxy S2 SIM Unlock again but it was unable to find the unlock code. And so I tried Helroz's Galaxy_S Unlock and that worked, sort of. Whenever I unlocked the phone with it it would lock back after couple of hours or after a restart. But I could live with that. That was until yesterday when it stopped working. My signal bar is empty just like when the mobile is locked but the phone doesn't prompt me to enter the unlock code. Neither of the apps I tried before works any more.
I restored the phone to a backup I made previously - doesn't work. I flashed another ROM - nothing. I did a clean flash back to cm10 after wiping /system, /data, /chache and dalvik. Nada.
Is there anything I could try to restore my phone functionality to my s2? Or am I essentially stuck with a tiny non-gsm tablet? (the wifi works fine)
You should try the galaxsim unlock app it works after a JB update which blocks the older helroz partial unlock
galaxsim is free on the xda forums or paid in the store.
Thanks. I installed galaxsim unlock and when I open the app the only thing that it recognizes is the device model. Everything else is 'undefined'. On the bottom it says that "either your nv_data md5 file is inexistent / wrong or samsung md5 function has changed."
This doesn't sound like good news to me...
It sounds like your efs is corrupt, hopefully you have a backup. If not I think it can be fixed but is hard and something I don't know.
Even make a backup of the corrupt since it may have salvageable parts to fix the rest.
Even if you didn't make a manual efs backup a lot of kernels and roms do it automatically so check your sdcard and even the data partition (I have seen siyah kernel put a backup on it in a .siyah directory) maybe even look in old CWM backups in the data partition.
Well, that's not good. Thank you for helping me identify the issue.
Does anyone know how to deal with broken efs? I have made a back-up at some point and it sits in a Galaxy_S_Unlock folder on my phone I just don't know what to do with it...
Maybe try ktool on play store?
Sent from my Galaxy SII
well, ktool only restores from backups it made itself and my backup was made by Galaxy_S Unlock.
Reinstall galaxy_s unlock and use its restore function.
Ok, so I restored the old efs, and then used the galaxim unlock to unlock the phone. The app says the phone is unlocked and yet there's still no signal. I the "show details" menu there's nothing displayed under "Serial No", which I think is the issue? Is there any way to resolve that problem?
EDIT: Rebooted the phone and the serial no reappeared. Now it connects to the network and works in general. Thanks everyone for help. Enjoy the weekend.

[Q] GalaxSim unlock problem

Hi guys,
I've messed up and need help. Here goes...
I had a locked phone on the 3 network , a S3 I9300; and I wanted to unlock it. Simple I thought to myself.....anyways, I downloaded the voodoo unlocker after rooting successfully with Odin. Nothing happened it wouldn't read my T-Mobile sim card and I can't remember what I did exactly but I did press some buttons on that app in attempt to unlock the sim. I then realised that it was not compatible with the S3 and then I proceeded to use the GalaxSim app. I had to download busybox for that, after doing that I attempted to unlock it. Yipeee! Phone unlocked and everything green.....but not. I still couldn't register on any network(using manual method as well). I had even cleaned my SIM card(but not tried another sim card). I then unrooted the phone with stock rom and unrooted again to use GalaxSim......and pressed backup accidentally! That I means I am now with an unlocked efs folder as my default efs, I didn't check the IMEI number to see if it changed, but how I return it all to normal? Has my IMEI number changed or would it not show IMEI if I overwrote the EFS folder?
I need help, I'm confused.
What phone you post I9100 ?????
No or broken EFS then just restore your backed up EFS .
jje
sorry i9300.
No, the EFS I had was overwritten with the newer version when I reinstalled the app. Now I have only one EFS and that's the one currently installed(which says the phone is unlocked). The phone is not registering on any network. Is this a baseband issue or a unlock issue? The app is showing unlocked, it shows all the networks, but some are written as"forbidden networks" and I can't connect to any.
By the looks of it, the simlock will never return.

You cannot update an EFS with a newer version you can only restore your original backed up EFS .
Does the IMEI match that under the battery if not its a service centre repair .
jje
Oh and the platform is jellybean.
The imei is the same, but it is still "sim unlock". How can i redo the process?
your phone should be fine you restore your original imei or just copied your origanal imei again probaly for the best as you know you have a back up of it now
chances are your phones unlocked now and probaly just need to register the sim card with T-mobile to activate it
should always place the back up of your efs somewhere else aswell incase things do go wrong mem cards can corrupt
Both sims that i've used are contract. I can't register any. They all say disconnected on status settings.

You are breaking them on purpose then. It's against the rules to bump your thread more than once every 24 hours, you did it not even after half an hour

[Q] downgrade 4.1.2 please

Bought an I9300 s3 on eBay is locked to O2
Vodafone sim
Spoke to O2 no help at all. Call 202?
Doesn't make calls.
I've got an efs backup but from the 4.1.2 current stock.
Seems this won't downgrade to 4.1.1
Odined the stock 4.1.1 no joy. Won't boot.
Cwm an old miui 4.1.1 also no boot.
Odin back to stock unbranded 4.1.2 boots fine. Rooted cwm triangle away. Fine.
Whos is this phone? Apparently not mine.
How to down grade please?
Any help gratefully appreciated.
Super wipe after flashing rom helps.
Downgrade to 4.1.1 probably won't have SDS fix so may kill your phone.
If it doesn't make calls with O2 sim then IMEI may be blocked. It won't make calls on Vodafone, because it's locked to O2.
You have to factory reset if it wont boot.
Sent from my GT-I9300 using Tapatalk 4
So you're saying after cwm the 4.1.1 I should full wipe.
Then the business.
Then flash a safe kernel before upgrading back.
If I just odin the 4.1.2 stock back over surely the brick bug won't activate?
Flash 4.1.1, full wipe. Do your unlocking, flash 4.1.2
Sent from my GT-I9300 using Tapatalk 4
This went badly wrong.
Flashed stock region correct. 4.1.1
Flashed chainfire cwm root.
To allow wipe
Booted fine.
The fix as follows doesn't work as the final menu still not available.
Just dial the following keys *#197328640#Main Menu[1] UMTS*[1] Debug Screen*[8] Phone Control*[6] Network Lock*Options [3]Perso SHA256 OFF*(after choosing this option, wait about 30 seconds, then go back one step by pressing the Menu button then select Back, now you are in*[6] Network Lock then choose*[4] NW Lock NV Data INITIALLIZ ..... wait for a minute then reboot your phone
Even though I didn't execute anything as that menu option isn't there something bad happened.
I installed galaxsimunlock from the play store.
It now says invalid imei.
Glad I backed that up.
Still locked.
The saga continues
I would try an O2 sim before anything to see if the phone actually works or not .
Blocked phone are blocked via IMEI and require the blocking network to remove the block .
Report phone stolen network block IMEI get new phone sell the now blocked phone is fairly typical .
jje
If I buy an unlock code on the Web or at a store will it sort of the blocking from the network?
Don't know anyone with a micro sim on O2.
Thanks for your times
Edit.
I flashed back to 4.1.2 its ok. The baseband doesn't get replaced on downgrade and isn't understood by the older software. There is a post somewhere here about it.
This is what causes the odd error messages in that unlock app. Currently says can't read nv
Unlock code will do nothing if the IMEI is blocked, the phone is useless.
Take it to a phone store, for a small fee they will tell you if it is locked or blocked.

Are you now saying the phone is blocked ???
If so return to the seller / Ebay .
Unlock code will not remove blocked IMEI .
Usual reason for a block is phone is stolen

I agree if it turns out to be blocked I will. It was PayPal so he must be verified.
But I still don't know anyone with a micro sim. Shame they're not all the same size now.
I was just checking ahead of time. I don't want to pay £15 for a code and it not work.
I work weekends so I'll have to wait until Monday.
Thanks everyone you're being very helpful. Much appreciated.
Good news everybody!
We've got a delivery to...
- found someone with an O2 micro sim.
Works fine on O2.
Seems I'll have to go pay for a code online or in one of those seedy little shops.
Seems a shame. As I can alter my /efs backup and presumably restore it back.
If only I knew which file/s to change.
It's not the most obvious one that contains only three letters O2U
Unless galaxsimunlock doesn't restore properly.
Galaxsim unlock is fine. But you have to pay now because he removed the beta / free apk from his xda thread

I agree galaxsim unlock would be great. But as it now flashes a red bar
"Unable to read nv data"
And offers no option to unlock or pay. Cos it says in the help that it doesnt know it can unlock the phone.
I'll have to wait for an upgrade.

[Q] S3 I9300 (International) NETWORK UNLOCK PROBLEM

Hi,
I have a Samsung Galaxy S3 GT-I9300 locked to T-Mobile on Android 4.3 (baseband: I9300XXUGNA8) meaning it has changed the EFS parition to v2. The phone has been rooted as well. Is there any solution to remove the SIM lock? I have tried reflashing with older versions but the systems wouldn't boot up. I read that it can brick my phone completely. I tried using Vooodo unlocker and GalaxSim but error comes up, undefined. I tried EVERY SINGLE METHOD by using the codes: *#7465625# or *#197328640# but I either get Not registered on network message or some other error. In case of #0011# I can't pass the step 4 (when you type in 1 and the service should appear). The IMEI is fine, everything is fine as long as I'm on T-Mobile sim card (the signal works perfectly). I put any other foreign SIM and it doesn't ask me for the unlock code. Do you know what's the reason? I have bought an unlock code but I can't even use because any other method wouldn't work. Is there anything at all I could do? I'd really appreciate your help.

Try to flash an unbranded version, like this here: http://www.sammobile.com/firmwares/3/?download=28378
And than try it again with your code.

This particular firmware fails to flash it through Odin. I assume it's designated for GT-I9305, not I9300 ... I have tried the unbranded versions for my model anyway and I usually end up in the bootloop. Any other solution? Thx
Factory reset after Odin flash.
