[Q] Help unlocking please - Galaxy S II Q&A, Help & Troubleshooting

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!

Any chance you could link me on a good up to date guide? I don't want to brick my phone or anything, I thought I would have been on a Stock ROM since I'm on Jellybean now.

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!
Thanks

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.

[Q] Does Unlocking a SGS II works successfully

Has anyone actually tried this guide to unlock a SGS II to work with any GSM mobile operator's SIM worldwide.

I am a novice to Andriod world, however I am planning to buy a SGS II. If the method above does really work , then I might have the possibilty of buying an operator locked handset to be unlocked laters for usage with my operator.
It is a request to make more detailed sticky for a final and tested step-wise guide for this unlocking procedure for the benefit of the community.

What is apk and how can it work. Is it to be run on the PC or the phone. What is the way of installing it.

Ups, sorry for not being clear enough...
An apk is an android installable file.
In the following thread you will find a link to the apk itself (for manual install) and a link to the android market for automated install.

The only downside is that this app needs root to extract the unlock code. To root your device you need to follow the instructions on this other thread:

Thanks,
So theoretically if i gain root access to the phone and run the attached APK file , it will possibly find out the unlock code for the mobile.
This unlock code would be SIM dependent (depending on which service provider's SIM i have inserted) or the handset specific, meaning that once the handset is unlocked it would accept virtually any service provider's SIM worldwide.
Thanks for the information.
The code is device specific, and will block any sim not being from your provider.
If you gain root access ,which is pretty straightforward with the guides available here in the forum and run that app you will get your unlock code.
Depending on the carrier you may even get an unlocked device. O2 seems to be giving both locked and unlocked phones.
Cheers!

From the above statement, I am a bit confused. Does it mean it will not block any SIM from any service provider.
I intend to buy a locked set from UK (which is usually when you buy a handset with contract) and unlock it to use elsewhere in world. The reason is obvious cost benefit which you get when buying a set with contract.
Is it possible via using this method.
Thanks.
What I wanted to say is that the unlock code does only depend on the device, not on the sim card you insert into the phone.
The sim lock, which that code removes, blocks any sims from providers other than your own.
You will be able to remove the sim lock with that app. The app will give you the unlock code you need.
On top of that, some of the O2 handsets that you buy subsidized are not sim locked (some are, some aren't) so, if you buy the phone from them on contract you may be lucky and get a sim free phone.
Best Regards.
Like wise some PAYG O2 are unlocked .

Alright, guess i would give it a try too.
Just would appreciate if you can guide with the following :
1. Does the phone needs to be in the home network (with the original operator SIM) in order to perform the rooting and install the APK file to get the unlock code.
2. Can we insert any other operator's SIM (which would be locked ofcourse) in the handset which may or may not be in the same country/network and still be able to access the phone main menu or screen to perform the rooting and hence unlocking activity.
3. How to install and run the APK file after rooting the device ( i see there already are other guides about how to perform rooting).
Thanks.

It's difficult to brick a phone with the unlock process because it's not something that can "just be done" to a phone. You generally run an app that gives you an unlock code. You then insert a SIM that shouldn't work, due to SIM locking, and it asks for the code.
This app works...

I thought that if you entered an incorrect unlock code several times that it would screw the phone up, and in the article it mentions that if you run the app more than once it may "freeze" your phone.
Make sure you back your efs up before you try to unlock. Just in case.

Its impossible for Chainfire's APK to brick the phone, it does not make any writes only reads, this is of course the same for my manual method.
If you are rooted running the MIUI ROM and unlock the phone with this app will the phone still be unlocked if you flash a stock ROM back onto the phone?

The unlock is permanent, the only way your phone would be re-locked would be by restoring your EFS which was locked.
Steps i have done :
- Root phone.
- Backup EFS with "EFS Pro" (just in case)
- SGS2 SIM unlock code finder
And done ... all operators unlocked.

[Q] Trouble unlocking i777 after root.

I have root, the first time it froze and didn't sent a test correctly. So I tried it again using Super one. Now I have superuser. Tried both apps on the market and neither one seem to have worked thus yet.
When I try Herolz Galaxy s unlock It is unable to copy EFS, All it says is Done, Error, Not saved. And yes there is an SD card present.
The GS2 unlocker also available on the market will fart around for over 5 minutes and say unlock code not found.
What gives am I doing something wrong? I have tried it with the sim in and with it out. Using Family mobile from Walmart, so I am guessing Tmobile sim card.
Please give me some other root around this.

I didn't know ti wasn't stock. LOL . I just bought it used from a shop here yesterday as am upgrade from gs1. Could you possibly direct me in the right direction as I am unsure what part you are talking about mot being stock.
Than ks in advance
you know you'll only get Edge on Tmo bands.
KH7 is stock, but you stated you have root. Did you do it? if not then check the android Development forums on how to get back to stock. and start the root proccess again.
I got the root through superoneclick. It seemed it did ok as the secong time I went through it said it was already rooted. as for the crappy internet it won't really matter here as we don't even have 3g here in this town for t-mobile anyhow.
if I un-root and re flash back to stock just using the button press combo work? Any why does it only get edge on tmobile?

Unroot and back to stock would require Odin/Heimdall.
Only gets Edge on Tmo because its an at&t phone. different bands for 3g.
I have used Super One Click in the past, but its just easier to flash a rooted kernal in Odin/Heimdall, then flash a custom ROM via CWM.
Back to stock is mainly because SuperOneClick is an old tool. and then starting fresh with the latest.
But I had no need to unlock my phone, but from what I've heard its very simple, and most dont have any issues. using the app from the market
I am not afraid of ODIN. I have done that in the past but I did have a huge problem with the GS1 installing an older kernel. I just about bricked the phone. I had to use the HEimdall or what ever it was to get back in it.
On these phone with a custom kernal and rom will it automatically unlock the phone? I am just afraid of using the wrong one and in this particualr section I am sure as to where to go. It doesn't give a whole lot of detail and with the cryogen mod thing it is getting places where I am not sure if I want to really try that. I would but the information is spaced out so much I am afraid of missing something and buggering everything up. What should I have to worry about when doing this?
Also it is the software unlocking I am having problems with.

Custom kernal will not unlock the phone to be used on a network other than at&t.
Software unlock? assuming you mean using s/w to unlock the device, yes thats the way i understood this thread. I cant really tell ya much about that, but i have heard that its easy and works fine, which is why you should go back to stock first, to get rid of anything messy leftover from using an old rooting method.

AT&T hardware handles different frequencies than T-Mobile hardware. It's a limitation of the phone's capability to receive the signal.

Trouble Unlocking After Odin Root of
I rooted my phone using Odin and the Siyah-v3.4.2-nomswap-I777.tar file in the PDA. The phone passed, and it reloads with the triangle on the start up as expected. However, it then says "enter network lock control key". It has nothing to do with the sim, as the sim works in another phone. I have done the process several times, running odin back to the original factory settings with I777UCLE5_I777ATTLE5_I777UCLE5_HOME.tar.md5
Could someone please tell me how to get the phone unlocked?
I have done this process before with another i777 phone, and it worked fine.

[Q] Sim Locked GT-I9300

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.

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.

[Q] Empty IMEI, Baseband version unknown, EFS folder backup exist, restore efs not he

Hi,
I used Android 4.1.2 and CM10.1 - on Samsung Galaxy S II model I9100.
During a phone conversation it was hanged up, and the phone could not connect to the network anymore.
I got an error when tried to manually search for network operator, which lead me, after a research in the net, to find out that the IMEI of the phone is empty. I see also that the Baseband version is 'unknown'.
I have a backup of the efs folder and tried to restore it by manual overwrite it - with no success.
I also followed the guide to recover manually the IMEI from here: http://forum.xda-developers.com/showthread.php?t=1264021 with no success.
I tried to get back to a backup of the original ROM I used before (this time using ODIN), and now I get NULL/NULL in the IMEI and I still get Baseband 'unknown'.
Also re-installing the radio did not help. now when looking for network operator the error is different - now it is telling me that there is no SIM card.
the NULl/NULL IMEI and Baseband version is 'unknown' are still here and I still can't connect to the network.
last input: after 2 days of phone being unused - it suddenly got back to work, the original IMEI got back in, and it connected to the network. this happened without me doing anything, and it held for half a day, then the phone got back to the non-functioning mode as described above, again in the middle of a phone conversation.
I am out of new ideas, all related threads in here did not help.
Can anybody help ?
Does anybody know the reason for this issue?
Can tell what is the thing that is probably corrupted, and in case that the problem is with the files in efs folder - why doesn't a restore of the efs folder (including chown for nv_data.bin to user radio) did not help?
Thanks !

EFS is corrupt.This was a bomb waiting to explode.I suggest you to go back to stock JB 4.1.2 ROM (see my signature),and flash Apolo kernel.Go to recovery and restore backup.Do not overwrite it manually.Do it in Recovery.
New inputs

Hi GamingDj,
First thanks for the reply.
I want to add more inputs and few questions:
Right now, after more then another day that the phone was not functioning - it got back to operate again, and again, without me doing anything that will cause that to happen.
During the last time that it happened, this held the pone in a working state for about half a day until it hanged up on me during a phone conversation I had - and the phone stopped working again, so I am not very optimistic about the phone getting back to work for good right now....
I have a bit more data that I forgot to mention before:
1. About a day before this problem happened, Avast anti virus offered me to update the Avast Anti theft software, this required root access and I don't know if it has something with the reported problem or not.
2. The efs folder was "handled" by GalaxSim Unlock, after the phone got locked due to official upgrade to JB. Originaly this was an O2 locked phone, then it was unlocked with a code, but due to the upgrade to JB it got SIM locked again and the codes did not work anymore, which caused me to use the GalaxSim Unlock application - that indeed unlocked my phone. I know that the GalaxSim Unlock application changed some data in the nv_data.bin in efs folder, but after it unlocked my phone it was working fine for about a month or more, so I can't tell that this is the cause for the suspected corruption in the efs folder.
I have both backup of the efs folder before and after the unlock operation by GalaxSim unlock application.
Can you explain in more details:
1. Why you suggest to flush Apolo kernel? is it in order to have the phone rooted? can you give a link for this kernel?
2. Restore backup from where? should I have a backup file that you point to? not sure what backups I have that may have data that I don't already use.
3. Does the new data help with debugging this issue?
Thanks again.

[Q] How to Unroot Galaxy S2 i-777 ATT outside of USA ?

Hi all
I have a galaxy s2 i777 ATT - I can't find its own place on this forum so please forgive me if this in the wrong section
My S2 was unrooted and then I loaded omni kitkatt on it which locked my sim . big noob mistake I feel really dumb believe me.
Now I had unrooted it in the with odin and loaded Siyah ics to finally root it because the sim got locked. I live outside of the USA and nowhere near an ATT network. It has the CWM recovery on it
So all was well until someone ( my nephew ) decided to load omni again and then he loaded Carbon on it
The strange thing that is happening right now is that I do see Superuser in the settings but my sim is still locked I tried to use galaxys2 unlock but it doesnt do anything.
No biggie right but now it turns out my USB port is not working.
So here are my questions :
- How do i get my phone back to stock without a pc and root it (I live outside of the usa thats why I believe my sim gets locked ) so we can use the phone again to call
or
- Can I use mobile odin to load the stock version of android back on it and then unroot it again so I can unlock my phone ?
- Can I try to use frama root to check if my phone is really rooted and if so can it help root my phone ?
For now I'd just like to get it back to stock and root it ( so I can unlock my sim)
I need your help .
Thanks
Maddie
The good news is that you're in the right place, so welcome!
Next, I'm guessing you're still on Carbon? If so please look in System Settings >About Phone and please tell us the rom, kernel and modem version currently installed on your device. It's always good for us to know your full setup.
Regarding the sim issue I have virtually no experience with it, but I do know you can simply call AT&T and they should supply the unlock code (if you have a working phone, of course). You may have to supply your serial and IMEI #, both of which can be found on the battery, so probably best to have that handy if you call them.
You don't have to be on bone stock to unlock your phone, you just need the unlock code... and hang onto it for as long as you own your i777!
Have you tried the GalaxSim Unlock application? Here is a link to download the free version. You may find that you can unlock your rooted phone without flashing back to stock. I have limited experience with this application. I recently sold an AT&T SGH-I897 Captivate which I unlocked successfully with this app while it was rooted on stock Gingerbread. The purchaser wanted KitKat so I loaded CyanogenMod 11 onto it, and checked that the unlock was still present.
To answer your other questions:
I'm not sure why you are asking to "unroot" the phone after returning to stock. As far as I know, you need to be rooted to unlock the phone unless you have the unlock code from AT&T.
You can flash stock firmware with mobile odin. The stock package does not contain root, so your phone will automatically be "unrooted." If you go this route, I would suggest you use the I777UCMD8 stock tar from the Download Repository.
From stock UCMD8, you can successfully root the phone with Framaroot using the Aragorn exploit.

Hi thanks for helping out this is what I got:
CARBON-JB-NIGHTLY-20130929-0603-i777.zip
Kernel version
[email protected]#1sunsep2906:36:49 edt 2013
ROM: CWM based recovery v6.0.3.8
I cant find modem version
I'm in south America and I had bought the phone from the usa unlocked.
When Omni was loaded on the phone it locked my sim and I never had received an unlock code.
So when I went back to stock my sim still stayed locked so I rooted it again with Siyah ICS via odin so I could use galaxy unlock to get my sim working again.
How would I go about getting that unlock code for my sim from Att ?
Do you think I could email att ? I did find my serial number and imei #
The reason I wanted to go back to stock and than unroot it with the siyah ics kernel is because that seems to be stable for my phone.
Yes I have tried using galaxy unlock but it doesn't work it doesn't read the Imei nr and the sim stays locked
Honestly it looks like my phone is half rooted now
BTW the the sim being locked is more like a carrier locked I can't use the sim with my local telecommunnications company.
Thanks again.
