I have used chainfires superuser and cwm programs to root my s3. I was looking for a jellybean upgrade and found this one:
youtube.com/watch?v=_PSt8b5D2dM
Like a dumbass i didnt look if there was one here, and I ran this one.
My phone is (was) a carrier unlocked GT-I9300. After running this ROM, the phone boots and everything works except the actual phone functions. WI-FI, internet... everything.
Any ideas how to un-sim lock or un-carrier lock my phone that this ROM caused?
Bump... No ideas at all???
it's not a sim lock, you probably messed up your imei. check if it matches the one under the battery
once the phone is unlocked, it is unlocked forever. no roms re-lock the phone! what do you mean your actual phone functions do not work? what are you f/w details? more info needed.

Not quite true on the s3. Some unlock methods are reversed when upgrading to jb

OK... details... had root access to phone using chainfires programs, which i bought. Was looking for Android Upgrade. I found one on YouTube that had good reviews, after all that's where I found chainfire's root process.
Installed ROM from download link to YouTube video above. Would not recognize a SIM card after that. My carrier does not lock their phones. Everything else on the phone works... wifi, internet, all the functions except phone and text. Took it to my carrier. They wiped it and put their version of Android on it but it would still not recognize the SIM. The tech told me the ROM I installed had SIM locked the phone.
I found the IMEI under the battery... but not on the actual phone software itself.
Thanks for the replies.

Sorry. Now there are details.
Have read lots of posts on here... nothing exactly the same on the s3. Lots with restoring the imei, but my numbers match.
All i can find is people saying to send it back to Samsung and maybe they will fix it.
Any direction is appreciated.
I verified with my carrier that their gt-i9300 comes SIM unlocked. When I put my SIM card in the phone, it asks for the SIM network unlock pin. I have tried everything my carrier gave me. hey said I would need to know which carrier the custom rom was from in order to be able to unlock it.
The video on youtube where I got the ROM was from "theAngelofMusic" who is also in some XDA videos, or at least linked to some of them. I have asked her through the comments there several times but she ignores me.
I have searched the SD card for the efs fiels to no avail. I have read numerous more posts here but can find none with the same specific phone and issue.
Ideas???
try a different sim card
Carriers don't supply custom roms .
Your source for the rom was a bad source in my view .
All i can suggest is try the Kies restore to original firmware .

One presumes that you have read the identical posts and tried as Glenbun ssays another sim / network.
But the whole thread does not make real sense
Carrier unlocked then a rom locked it .>> suggests firmware was possibly for another phone or damaged .
Service put their version of Android on it very very odd Android as opposed to Samsung firmware .
Have you restored your backed up EFS folder ??

Let me start over. Phone is a GT-I9300. Our carrier is West Central Wireless, which is a small local carrier. The phones do not come from WCW with any type of lock, meaning I can take them wherever and use any SIM card. Not trying to be difficult.
The phone was rooted using this process: http://forum.xda-developers.com/showthread.php?t=1957273 Then I ran a custom ROM from this link: http://www.hotfile.com/dl/173577508/3316be3/I9300XXDLIB_I9300OXFDLI1_XEO.zip.html which was linked to android authority from YouTube, which is also where i found the chainfire root info. This is the YouTube link: http://www.youtube.com/watch?v=_PSt8b5D2dM
Once i flashed this ROM, I could not get the phone to recognize my SIM card. I tried to restore it to the original and still nothing. I took it to a tech at WCW. They put the current version of Android on it but it will still not recognize a SIM. I have tried one of theirs, my wife's, and the one from the phone. They all ask for a SIM unlock PIN. I got the two that WCW said might work and neither work. They suggested the ROM i loaded from YouTube was carrier specific. After getting it back from WCW i cannot find the efs files.
Everything on the phone works, less the call and text. Internet is fine as long as I use WIFI. Same with email, google play, etc...
I tried a couple of different unlock codes from the internet. None worked and thankfully all refunded the fee as they said they would.
I am trying to figure out if it is possible to restore this phone to actually being a phone. Hope this helps.

My samsung galaxy II is constantly losing network but when I put my SIM into my old phone it works fine. I've tried everything I could find on here i.e roooting, upgrading to ICS but have had no luck.
I bought (well I paid out his contract) the phone from a friend who moved overseas and he was on a different network (Optus) and I'm on Vodafone but my SIM works (just not all the time! ) so I don't know if that has anything to do with it! Anyways I wont take it back to Optus because I wasn't their client to begin with and Vodafone wont help,
Any help is much appreciated as I'm really frustrated! Thanks for reading :laugh:

Even I had a similar problem a while back, any SIM card, would loose signal completely only on the SII turns out it was a hardware issue, I had to give in my phone to the service center.
To flash a modem if you have heimdall installed, open up the command prompt/terminal in the directory where you have downloaded the modem and extracted the modem.bin file, and type in
heimdall flash --modem modem.bin
or you can use the GUI it has an option for modem, but the modems aren't universally good for everyone, they are region specific, in my country [India] I use the DDKL1 modem, you should look for some modem that's native to your region.
OK. What you need to do is read the Stickies & brush up on Android/SGS2 basics.
Secondly, if the phone is rooted & you have CWRecovery (boot into recovery by turning the phone off, then holding power/volume up/home buttons), you can easily flash modem packages.
I'm also using Voda AU, so I'll get you started. The famous DUKJ1 modem has worked well for many people using Voda in Australia. Unfortunately, XDA doesn't seem to want to allow me to attach files to forum posts at the moment, or I would have attached a copy of KJ1 to this post. Sooo....Here's a link where you can get it
Also, if you do a Google search along the lines of "XDA SGS2 modems" or similar (use your imagination), you should find plenty of posts from here which have links to modems you can flash if KJ1 doesn't work well for you. If that is the case (it doesn't work well for you), then it's a matter of flashing as many modems as you have to in order to find one that works well for you.
The issue could also be caused by the gear/spectrum Voda is using in your area (hence your sim works well in another phone). I guess you're only going to find that out if you contact Voda & ask for support (after you've tried every solution you can find on here I guess).
Now, if your phone isn't rooted, the Stickies have all the information you need in order to root it.
Edit - Also, questions go in Q&A ;-)
Thanks guys, MistahBungle will try the DUKJ1
Also would anyone have an idea as to how I can delete all the optus(old carrier) stuff off my phone?? Ta
You need to have a rooted phone to get rid of the bloatware. You can use an app like Titanium Backup Pro (Look for it on Google Play) to uninstall or freeze (which I recommend) apps you don't want. This thread is a good starting point for working out what you can/can't remove/freeze.
To our friend who added the tag to the thread, we know that Captain Obvious, thanks very much. However for someone new/who currently has little Android/SGS2 knowledge & already has a pre-rooted phone, avoiding Odin (and the inevitable problems many n00bs have with it) & using CWRecovery if it's already on the phone sounds like a sensible WTG to me.
So I accidently have locked myself out of my phone by changing my number to another network and thinking I could still use my current SIM in my phone until I got it unlocked.
I haven't been able to send or receive texts or anything for around 3 days now.
The place online I was getting it unlocked at said there was a delay with Samsung so they refunded me.
I tried the unlock apps but they don't work.
In GalaxSim, it says my phone is unlocked by when I try another SIM it doesn't work.
In the FAQ it says this could be a second SIM lock by the service provider, and to fix it I have to flash a full unbranded Samsung ROM.
I was wondering how I do this?
I'm on Cyanogen 10 and I currently have Jellybean on my device but I'm not too sure on what I have to do to flash to this ROM and if it will erase my data?
Thanks for any help!

CM10/jellybean is not a "stock" rom. CM10 is a "AOSP" based rom.
Stock rom refers to your devices/carriers default rom, ie Samsung based rom. Get your needed rom from sammobile.com
Flashing Guide: http://forum.xda-developers.com/showthread.php?t=1075278
If you want to unlock your device use the search there is plenty of topics if you use keywords like "sim unlock" etc.
Oh so I have to reset my phone pretty much? Can I go back to Cyanogen 10 after I get the stock ROM?

I didnt say you have to do anything however you may have compatibility issues unlocking sim so would probably best to go back to stock.
Yes, you can go back and forth to any rom you want.
Flash stock rom via odin (download mode)
Flash Siyah kernel (again in download mode)
Reboot into recovery and wipe data/factory reset.
Boot Android and use sim unlock etc.
Reboot into recovery and flash whatever rom you like.
Thanks for that, I went onto that site you mentioned, sammobile.com and I chose to do their unlock method with SRS, it was only 15 euro so I'll see if it fixes it!

Are you crazy?
There is plenty of ways to do it yourself for FREE if you would just stop been lazy and use search button.
Obviously I'm wasting my time, waste your money.
1) Get Mobile Odin Pro for 3 euro and download this Unbranded Stock ROM:
http://www.sammobile.com/2012/11/15/i9100xxlsj-%E2%80%93-galaxy-s-ii-android-4-1-2-jelly-bean-test-firmware/
2) Read Mobile Odin thread by chainfire:
http://forum.xda-developers.com/showthread.php?t=1347899
3) Flash the downloaded ROM following the guide above.
4) Check if your network still locked, If it is check this thread out:
http://forum.xda-developers.com/showthread.php?t=2070375
5) Tell us how you did.
When I try run Mobile Odin it gives me an error about not being able to detect the device. It's not asking for super user privileges either?
your device is not rooted? weren't you in CM 10.1?
What device are you packing? GT-I9100?
I followed everything you said and my phone is still locked. No luck

It was rooted but then I did a root checker and it said it wasn't, must of lost it after changing to CM 10 I think.
I downloaded some auto rooter and that rooted the phone for me. Then I followed your instructions and now I'm freshly formatted but still not working. Tried all the unlocker tools again and still doesn't work. GalaxUnlock says I'm already unlocked so it must be a second network lock.
But in his instructions he says that flashing to a stock Samsung ROM fixes it, but I thought that's what I just done.
sure you don't have an IMEI issue? You did back EFS folder before you flashed for the first time right?
check you IMEI by dialing *#06# and see if it matches the imei number sticked below the battery.

IMEI matches the one that I had before I started trying all this and matches the one behind the battery.
In the Galaxy Unlocker app I backed up the EFS files when it asked me tther than that I haven't touched them really. Any recommendations? I've tryed pretty much everything I have seen.
I'm searching for the network info key-in code, for you to see what's locked and what's not. Can't seem to find it tho.
Do you have another carrier sim card to put in & see if it asks for an unlocking code?

I currently have my Meteor sim card in the phone, that's the company I was with for years.
The phone lets me browse and use apps and stuff when this sim card is in it.
I have another sim card for 48 who I am changing to, which asks for the unlock code.
Before with GalaxSim Unlock, it said I was already unlocked. I downloaded an old version now everything says undefined, and said it can't read the nv data, however I am nearly positive I have backups of this as I saw them on the card.
Galaxy S2 SIM Unlock just gives me an unlock code of 00000000 which doesn't work and Galaxy S Unlock doesn't work either, altough it says it does

Well, now we know that you are indeed locked, thats good.
busybox installed on your device?
if yes, try installing another version (older/newer) once downloaded install it and keep it working in the background, then run the unlocking apps again

I have Busybox installed, but I have two versions, BusyBox free and BusyBox installer, don't know if it matters that I have the two of them.
I have went to a much lower version of it but GalaxSim Unlock still says it can't read nv data.
I tried that program also and it says my Video card isn't supported :S
And hit the restore button in Galaxy S 2 Unlock and GS2_Repair so I presume it got restored. Where should the efs folder be located so I can double check?

I also got 2 busybox (free 8.9.7 & installer 4.1).
GalaxSim Unlock should have a restore button, dunno the location of the back up, but the EFS folder should be in the data folder, u'll need a root explorer to get to it.
Hi,
I'm currently on android 4.1.2 and every time I try to update to cyanogen 10.2, I have the same problem.
I followed meticulously the flash procedure but when I boot, the phone asks me a certain number of times for my pin number (I noticed that this number is random). After that I entered my pin x times, the phone unlocks but I have no network connectivity, and can't send texts or make calls.
I looked for people with the same problem and only found this link
and found that I had exactly the same problem as `tux821`, and tried the solution offered by codeworkx by flashing the RILs at this link
That didn't work, I thought that maybe it was related to the sim lock so I bought `GalaxSim Unlock` but that did not do the trick either.
`tux821` said that he got it working by doing this:
I did contact Cellunlocker they adviced Samsung/factury unlock codes.
The network unlock code fixed it instantly.
Click to expand...
Click to collapse
I had to flash back to a 4.1 ROM but I'm hoping that someone can help me to avoid contacting Cellunlocker
PS: my IMEI was correct
Thanks in advance

Well... I flashed again CM to give you those informations and I had no problems at all. It's kinda disturbing because I did the same procedure as I did the last two times and this time it worked perfectly.
Just for info for some potentials users that might have the same problem, here's what I did:
-- Reflash to official 4.1.2
-- Root the rom with CF-root
-- Install CWM from rom manager
-- Reinstall CM
I'm sorry to have bothered you with something that works, hope this can help some other users
Hello People
Again, I'm with problems with my S3 since the one time decided to test a custom ROM which turned out to screw my IMEI and got to it back working with BOX in repair service.
I n order to see if the BOX fix did actually solve my signal problem, it was suggested to me in a previous post that I flash the same stock rom via ODIN. Before that, I backed up current EFS as well.
Unfortunately, it seems the problem wasn't entirely solved. Same as before: both my IMEI and S/N are untouched (S/N does not coincide with S/N in the back of phone) and though it says I have a full signal, I'm not registered in network and i can't make or receive calls, sms, etc. Even though I restored the EFS folder, nothing happens.
I really wish not to go back to repair service again. What else can I do about this? Many thanks and excuse my rant. Hope I was thorough and clear on the problem. I also have a EFSv2_basebands_opt4.zip file I downloaded somewhere in xda . Would that help?
Many thanks.

I would still like to solve the problem at its roots: to fix the "not registered in network" problem whenever factory reset or stock ROM flash via odin is done. That is simply not normal. I might be selling the phone soon and the new user won't most probably know he/she would have to apply a patched kernel or etc.. ( let alone about rooting the phone).
Basically, bring the phone back to it's original sound state before I tried out the custom ROM. What can I do about that?
Hope I'm not being annoying.. just trying to get to the bottom of things

There is nothing you can do without your original efs backup.Only a service repair can fix it.

Understood. I think I have the original EFS in my SD, though I tried replacing it once and it didn't work out... I suppose I'll have to make do. Thanks for everything man
Flashing modem with Ariza patch was bad idea. Your efs folder is screwed up now and you are addicted to constantly flash this dirty workaround.
If anyone have problems with registering in network please check your device serial number first. It must be the same as on the sticker under battery. If it's not then type *#0011# and check info under IMEI CERT. If there is FAIL info then you should use any box ie Z3X to correct phone's serial number. It takes only few minutes and is cheap. It's better long-term way than patching and permanently destroying your efs informations.
If you have backup then you should flash normal modem and restore original efs partition. Then find any GSM service center with box and tell them to fix serial number. It shouldn't cost more then 5-10 dollars.

If it's not then type *#0011# and check info under IMEI CERT. If there is FAIL info then you should use any box ie Z3X to correct phone's serial number. It takes only few minutes and is cheap. It's better long-term way than patching and permanently destroying your efs informations.
If you have backup then you should flash normal modem and restore original efs partition. Then find any GSM service center with box and tell them to fix serial number. It shouldn't cost more then 5-10 dollars.

I have never flashed the Ariza patch nor have I even mentioned it on my previous posts explaining the problem. Fixing the s/n issue is indeed adviseable, but paying to correct s/n using box here where I live is ASTRONOMICALLY expensive. They should answer for never having fixed it, but they won't. Here is a hell of a lot more than 5-10 dollars, unfortunately.
Believe me , I'm no happier in applying this sorry fix every time I want to factory reset or upgrade, etc; it's the only option I have left at the moment.
Those files you have flashed, I mean kernel and modem are patched with Ariza's method. It is called Ariza patch and it is latest solution you should take to resurrect your phone because it is a destructive one.
Sorry to hear that you can't repair it as it should be especially if you want to sell this device.

Hello People
Again, I'm with problems with my S3 since the one time decided to test a custom ROM which turned out to screw my IMEI and got to it back working with BOX in repair service.
I n order to see if the BOX fix did actually solve my signal problem, it was suggested to me in a previous post that I flash the same stock rom via ODIN. Before that, I backed up current EFS as well.
Unfortunately, it seems the problem wasn't entirely solved. Same as before: both my IMEI and S/N are untouched (S/N does not coincide with S/N in the back of phone) and though it says I have a full signal, I'm not registered in network and i can't make or receive calls, sms, etc. Even though I restored the EFS folder, nothing happens.
I really wish not to go back to repair service again. What else can I do about this? Many thanks and excuse my rant. Hope I was thorough and clear on the problem. I also have a EFSv2_basebands_opt4.zip file I downloaded somewhere in xda . Would that help?
Many thanks.

May i ask a few questions about your problem?
Which version were you using when you desided to use a custom rom?
Was your phone ever rooted before installing a custom rom (when you were on official)
Did you upgrade your phone before? (Official via ota or odin)

I was on 4.2.2 leaked version ROM some guy installed at a repair service some time ago when the phone belonged to my mother. I was actually rooted using the CF AutoRoot method, with Philz CWM recovery. I decided to change to a custom 4.3 without having changed first to a stock 4.3.
The problem came when, within the custom ROM's aroma installer, I ticked an option to upgrade the modem to some build I can't remember now and my signal became screwed up. I informed this in the developer's custom rom discussion thread about the issue to which he replied that the problem was that the EFS folder tried to convert from v1 to v2 and failed (this was when I learned of the whole efs version folder change since build XXX (don't remember).
I download a stock unbranded 4.3 ROM and flashed it via ODIN, believing that would solve the issue; it didn't. Finally, I became desperate and took it to a repair service where they used box. Apparently, late did I notice s/n was not the same as the one in the back of phone. I'm guessing that would solve the problem? I don't know.
i am sorry for your loss . i wish you had all that info you learned before a try and fail. now that your imei number is a clon number, and once a box tempers with that you cant go back even if you have your orijinal efs folder or backup. you should always have that 2 patched modem and kernel files on your sd card just incase. you can use custom 4.3 with the patched files and get a signal but you will always have some lags after some time because of the kernel. and lucky you samsung stopped updating s3 officially because patched files are only for 4.3. if you dont have a desire to use custom 4.4.4 kitkat roms then you are good to go and when it comes to sell the device, the price will be much lower then an original s3.

Well, actually, IMEI didn't get cloned; of that I'm certain. IMEI is just the same as it was before I took it for the first time to repair service. It was the S/N that got changed somehow. Should I get them to correct the S/N, and use the original EFS folder (I found it, i think), would that correct all problems?
S/N number is the same with imei number as when you dial *#06# . And as i said before you cant go back even if you have your original efs folder. Dial *#06# and check your imei number from an " imei check site " you can find on google search. That will tell you what i mean.
There are: IMEI, device serial number and Android serial number. First two numbers are on the sticker in battery Bay. They must be correct because are used to authorize IMEI certificate.
Samsung's IMEI begins from 35.....
Serial number usually from RF......
If you see serial number in HEX format in phone's info section, something like f1abcadef1.. than it is android not device serial number and this mean troubles with authorize SIM card in operator network, even if it shows proper signal power.
I don't know there is any secret code to display serial number but there is plenty of phone's info apps in playstore which displays this alphanumeric string.

It's been a while my S3 has been dead now, virtually rendering it into a WiFi tablet. Let me give a backstory.i had originally bought the phone and it was running 4.0.4, rooted. I wanted to go onto a different software so I came across Cyanogenmod. I flashed it with the automatic tool on pc. It had been quite some time I was running it, until I decided that I wanted to go back to stock. I was a complete noob back then, and where I may now a lot more stuff about phones now, there is still alot to learn. Anyway, I decided to flash a rom called "Back to noot", using twrp. The flash had gone successfully however I booted up to find that I had the infamous circle with the line through it, where the signal should be. I did some more digging and had concluded that my efs had been corrupted. As I was a complete noob, I didn't know what the efs partition was and I hadn't made a backup of it. So I was without a phone basically. Recently though I flashed the latest stock 4.3 rom onto it. My IMEI and baseband are back. However my IMEI isn't correct, the last couple of digits are incorrect, resulting in me having to face the "not registered on network". This is where I am now. I'm without my correct IMEI. Can anyone please help me restore my original IMEI? I have seen on some forums where some people have flashed down to 4.0.4 to successfully recover their phone. However sammobile now requires a premium account to download a 4.0.4 rom for the i9300, weirdly. Can anyone help me to restore the IMEI? Thanks.
You can download firmware for the i9300 on fw.updato.com . Search for the i9300 and filter by version to find the one you want. I am not sure if it is possible to restore your imei without an efs backup though. Good luck
Are you referring to the digits after the "/"?
I've never heard that dowgrading the stock ROM would change the imei.

The entire IMEI is correct until I reach a certain point.
After the 3rd dash on the back of the phone, the digits follow "182/9". However when dialing *#06# on the phone itself the digits "4344/15". This is what I feel is causing the "not registered on network" error. I never knew downgrading can restore the phone. Ive seen on a forum that someone had recovered their phone by rolling from a higher firmware down to 4.0.4

Was the phone purchased brand new, used, or refurbished?
If the phone is running a stock 4.3 ROM, you can't flash an older ROM as the phone will not allow flashing an older bootloader.

The phone was purchased used. If I cannot flash an older version of Android does this mean it's no hope?

It's very unusual that the imei would change on its own. It would be even more unusual for the imei to change when flashing one stock ROM over another. I suppose it is possible but I have never come across a situation where such a thing has happened.
Since the imei on the label does not match the imei in the phone and it was a used purchase, I tend to believe the phone is a "frankenphone" in that it was put together with parts from different phones.
Did you check to see if the imei from dialling *#06# belongs to an s3?

Not if he flashed a firmware or rom based earlier than 4.3 and the phone has been 4.3. Efs changed at 4.3 and going backwards kills the efs partition because 4.2 or earlier can't read the new encryption.
There is a possibility that flashing earlier firmwares can write the imei back in, I've read something about this before. If all else fails then why not try it.. Its borked anyway.
Kies emergency recovery is another method but won't work if the phone was rooted.
I think have an efs of a now dead phone. It was a btu i9300 https://drive.google.com/file/d/1MiFFyCCeh1PFuQVZa-M4woreaofcDmrb/view?usp=drivesdk

Is this efs dead or working?

How you use it, no clue. I've never had to. It's from a phone that was eventually killed in an accident.
The files are as they were extracted. I zipped them up myself. It is not in anyway suitable to be flashed as is but if you can get the os working and root it you can copy the files to the correct folder, set the permissions and see what happens..
I thought seeing as I have no use for it someone else can, if they can.

The phone was successfully recovered by flashing the XXUGMK6 ROM, then flashing the Patched UGMK6 Kernal and Baseband that zuluman had given. However the phone only accepted one SIM card from a couple that I had tried, and the phone thought I was in a roaming state, meaning I couldn't use mobile data. Other than that the text message and phone calling functionality, which was the main focus of the repair, has been successful.
