I updated the app. Changelog :

- cosmetic changes

- better error messages.

- added a check for busybox

- modified some checks for more safety

- added full model string

- updated supported models (and the warning on unsupported models is not blocking anymore)

- added a "efs backup" button even if there was an error during prerequisite checks so that you can send me your efs if you wnat me to have a look at it.

@yoshi57

thanks for your efs folder, I'll have a look at it when I get some time.

@sergiuhusca

your gs3 has also been unlocked with SRS Samung Remote Unlock Client. I'll tell you more when I have done some research.

@Zlatko1983

If it doesn't work with the latest release, please send my your efs folder.

@slaman

Could you tell me if the latest release works for you ?

@uoY_redruM

I have never tested, tell me if it works for you (or just send me your efs folder so that I can confirm it should work).

New release shwo model GT-I9300, rest is undefined and error message unable to read nv data

[upgrading to JB now]

Edit:

Update done on LH6, Phone still unlocked :)
[Galaxy S III Themes and Apps] sergiuhusca:
Spoocky, it will be very useful if you can compare my efs with efs of our member from the thread which has the phone coded on orange!Sow we can see what are the differences.At service they told me..."the box give us a code!we enter the code on to device,and that its all!But like i told u when i go second time they rooted the phone and change the kernel!I don't know what metod is this...

It will be very nice if a member ho unlocked his device at a gsmservice,to make un update...and the phone to relock himself again!After that we will apply your method and see whatshapening...
[Galaxy S III Themes and Apps] shkippo:
any suggestion
[Galaxy S III Themes and Apps] Mopral:
Seems to be normal with v1.2 (check changelog)

Older show me GT-I9300 and last one show me GT-I9300RWASFR
[Galaxy S III Themes and Apps] shkippo:
yes you are right :)

but if you see my s3 is like yours from the same country but mine show GT-I9300RWAAFR it should be like yours SFR not AFR

on the box of my s3 i have GT-I9300RWASFR

did u checked my attachments !!!!
[Galaxy S III Themes and Apps] sergiuhusca:
At my box show only Gt I9300...

But on fus ceck show this...
[Galaxy S III Themes and Apps] spocky12:
The second unlock of your phone has been made with SRS unlock, so it's definitly not an official unlock (it could be considered as "temporary" as the patch done with my app : it'll depend on future samsung rom ril modification).

However, tt might have been done with an old version of srs (different from the one used by yoshi57) with a patch that I wouldn't call elegant : they patched nv_data.bin and removed nv_core to prevent any crack detection. That's quite dangerous as if your nv_data gets corrupted somehow, you'll lose your imei :(

If I remember correctly, you told me about a nv_core.bak and nv_data.bin in your external memory. If my assumptions are right, it might be a backup of the files modified with SRS. Could you please send both files to me so that I can have a look at them please ?
[Galaxy S III Themes and Apps] spocky12:
One of the method you used before using GalaxSim Unlock modified your model code, replacing SFR with AFR (or it might be kies, but I doubt so). I have no idea why it's been done like this. I don't know simfix, but I don't think voodoo can do this, so you might have guessed the culprit :) . The best would be to contact the author of the app to ask him why he did this.

I would recommend to restore a stock efs folder (or at least a backup of your nv_data.bin before any modification) and run my app again.
[Galaxy S III Themes and Apps] sergiuhusca:
I send you the files via email...

What shoul i do now?I was to them and they told,im the one who has this problem.They told me,they will search for a solution and they will make the device...

I shoul let the device exactly at he is in this moment?My efs backup is not good?

An update via Kiess cant solve the problem?:((

Why Srs need root?Its remote!No?
[Galaxy S III Themes and Apps] yoshi57:
SRS Need a root acces in any case:

First method : read unlock code

Root need to read nv_data.bin to get encrypted unlock code. I believe decrypting it is done remotly.

Second method: remove lock (I don't remember exactly the name)

SRS will directly modify nv_data (and more?), so it need root.

For me the "read unlock code" did not work so I use the second method.
[Galaxy S III Themes and Apps] sergiuhusca:
I don't know what to do in my situation...I have a new phone and now is almost gone... :((
[Galaxy S III Themes and Apps] shkippo:
thnx you very much

but if u saw my first screenshot with your old app its only show GT-I9300

BTW is that a problem if your new app show my device like AFR and not SFR !!!!!

and about my efs folder i didnt make a backup b4 i only backup it after using simfix and voodoo ... is that any problem with that
[Galaxy S III Themes and Apps] tux821:
YES DO NOT POST YOUR

IMEI ON THE INTERNET!

Guess a big popup with this message would be handy in threads like this.

Same about the efs images you post here.. better use PM to spocky..
[Galaxy S III Themes and Apps] shkippo:
seriously i was thinking about it but i am not the only one who did that

so what the dangerous about posting our imei !!!!!

thnx in advance
[Galaxy S III Themes and Apps] tux821:
Well I guess it can be cloned to another phone..

For the efs image i'm not sure but if this really contains all the magic , what would happen if I restore your efs backup to my phone?
[Galaxy S III Themes and Apps] shkippo:
yes i got it

you are absolutely right ;)

anyway i deleted my attachments thank you very much :good:
[Galaxy S III Themes and Apps] sergiuhusca:
They will resoft my phone...
[Galaxy S III Themes and Apps] spocky12:
The first screenshot with app v1.0 only shows GT-I9300 because it displays device model whereas v 1.02 displays product code (i'll change this in upcoming version so that should be clearer).

I absolutely don't know what's the internal use of the product code. It might be used by kies to find updates. Or that could be something else. So far, I suppose that the change from SFR to AFR waas intentional but I don't know why it's been done, so I suppose the dev could tell you.

Hey Spocky, I have a AT&T Galaxy S 3 and would love to know if this would work or not. If I sent you my efs folder would you be able to tell if it would work or not?
[Galaxy S III Themes and Apps] Sulan66:
Hello! I do not really know where to put app ... can someone explain it to me. Thanks

What do you mean you don't know where to put it? Download the apk and install it. It will be in your app drawer with the rest of your apps.

re-lock

will there be a re-locking tutorial as well? i mean for restoring purposes if my handset would need hardware repair from the official samsung repair center ?

or

just like vodoo, after a firmware update i just get back onto factory locked status ?

cheers
[Galaxy S III Themes and Apps] spocky12:
This app automatically makes a backup of your efs folder before unlocking. If you need hardware repair, you just need to run it again and click on "restore efs" to get back to a factory locked status.

Btw, voodoo doesn't get back to a factory lock status after a firmware update on purpose. It's a samsung modification on recent roms that does this.
[Galaxy S III Themes and Apps] eMiL112:

unable to read nv data

nothing else work even create backup 5 day i trying to unlock without sol even calling att they dont want give me code

and i need paypal for unlock online bad luck :p
[Galaxy S III Themes and Apps] Webb987:
TNX spocky12 !!! :good:
[Galaxy S III Themes and Apps] mikem75:
when you open the app, busybox ask for root permission? if not you did not finish to install busybox.

Open busybox and install some part from it.
[Galaxy S III Themes and Apps] spocky12:
Gs3 i747 is different from i9300, I believe it's qualcomm based. I'm sorry, as of now, there is no app that can sim unlock qualcomm based galaxy s3 (the method is different because the (un)lock information is stored elsewhere on the phone).

I'd like to add support for those devices as well, but it's quite difficult as I would need to buy one (and that's not the 2 donations I had until now out of more that 2k downloads that would cover the expense :p).
[Galaxy S III Themes and Apps] ASHLEY117:
just unlocked on omega v16.1 coolio. thanx mate

[Galaxy S III Themes and Apps] zamcum:
Hi

My first attempt to unlock my S3 was by Voodoo apk

Unfortunately I lost that EFS backup.

My second attempt was through a code generated by IMEI.

This code, not unlock my phone, but the seller guarantees that the code came directly from Samsung and is correct.

My question is, is there any way to get my phone unlocked with this code?

Currently the cell phone is unlocked with this application (thanks spocky12) and operating Jelly Bean DLH8.

PS if it is necessary for the purposes of study, I can send my unlock code and my Imei, to Mr spocky12, by PM
[Galaxy S III Themes and Apps] kaktuss77:
Hello

Thank you for your work but when I launch the app, I got this.

[Galaxy S III Themes and Apps] kaktuss77:
Hello,

sorry for corrupt image.

This is the good one ;)

But finnaly, I reflash the phone with an 4.0.4 android stock rom, re install busy box, and its work.

So I think there is a problem with BusyBox and JB ROM.

Thank you.
[Galaxy S III Themes and Apps] spocky12:
That's strange, some people reported it worked on JB... I'll have a look at it.

Could you please send me the logcat ?
[Galaxy S III Themes and Apps] biosong:
sorry to be a noob. but where do i get the logcat? i try to check setting in app but it doesnt respond
[Galaxy S III Themes and Apps] spocky12:
Just install alogcat from the market and click save file (of course you'll need to run my app before so that the logcat contains the necessary information).

Then just PM me the file.

Unable to read nv data

Hi - thanks for the app but I am getting the same error as kaktuss - i have a tmobile uk s3, I9300BVLG1. Have rooted via the CF-Root tool, and busybox version V1.20.2-CM9 is installed. I have the alogcat files if you'd like to see? :confused:

Hi

Unlocked my JB (AOSP by SuperNexus). Everything turn to green except Nv data consistency shows as "inconsitent" (see screenshot attached)

Is this normal...

Thanks in advance..
[Galaxy S III Themes and Apps] mypost888:
should root phone first?

Hi,

My Galaxy 3 is from Bell/Canada. This is a new phone, I haven't done anything yet.

Should I root the ROM first? If yes, please tell me how to root its rom? please give me a link.

After root, install Busybox?

Thanks a lot!!!
[Galaxy S III Themes and Apps] betaboy00:
based on all the previous post..sounds like it won't work for LTE NA version..and only work for international I9300 version.

Hopefully I'm wrong. Let me know if you succeeded or not because I'm looking to pickup a S3 as well.

thanks!
[Galaxy S III Themes and Apps] spocky12:
betaboy00 is right, as of now, this app can only unlock i9xxx devices, not US Gs3 (which are qualcomme based). Not sure about yours. If model number shown i9300, it should work fine. To root, search this forum for CF-root, and then install busybox from the market if needed.

If you never touched your efs folder before, this is not normal. Did it say "inconsistent" before clicking on unlock button or only afterwards ? Could you please send me your efs backup by pm so that I can have a look and tell you whether something is wrong on your side or on mine ?

Edit : now I see that you've still got a "backup efs" option in your screenshot, which means you didn't unlock your phone with GSU. Which method did you use to unlock it ? To me it looks like you replaced your nv_core with another one found on the web, which is exactly what the message in the screenshot says. If that's true, please restore an efs backup you made (?) before unlocking, and launch GSU again.
[Galaxy S III Themes and Apps] abadmi:
Sorry my poor english, i'm spanish.

spocky12, is possible to unlock my galaxy s2 with this apk. After install and run it, tells me that this partially unlocked.

[Galaxy S III Themes and Apps] smohanv:
Hi

Thanks for coming back. I initially unlocked with voodoo. After seeing permenant fix by using core patch i did the same. Somehow I lost the original efs copy and so I could not revert back to the unlocked efs. Is there a way to resolve this. I am worried that I have lost my backed up efs. I just assumed that flashing stock ROM via kies would rebuild this efs but it didn't rebuild efs to the original form. How can i get back to original efs state. My phone was locked to 3UK.

Thanks in advance.
[Galaxy S III Themes and Apps] tisazalay:
I'm afraid you won't be able to restore the original EFS if you didn't back it up. The only solution I think of is taking your phone for service but you can keep it like you are now and take it there if a problem appears. The voodoo creates a backup of nv_data.bin if I'm not wrong but I don't know if there is a way to create nv_core.bak from nv_data.bin... Besides the voodoo have proven not to be a problem (actually I haven't read that the other patch has been proven faulty yet, it's in the realm of possible). (NOTE: If you backed up the EFS (after voodoo) before copying the patched core file, you'll be perfect by restoring it and then running this. Voodoo doesn't affect the core file but data.bin and the latter is created from the core to the best of my knowledge)

Keep backups from this point onwards of everything just in case.... so that you can switch back at it if at any time something goes wrong. Right now everything is working right?
[Galaxy S III Themes and Apps] smohanv:
Hi thanks for your help. Right now everything is working fine. I am using SuperNexus (AOSP) ROM and so fas so good. I will surely keep a copy of efs from this point onwards. In case if want to send to Samsung to flash with their factory jig, I don't know how can ask them. Because of I talk to them much about efs and etc.. they will claim that I have broken warranty by rooting it. How about removing efs folder and flashing ROM using kies (just a thought and I am not an expert).

Thanks...
[Galaxy S III Themes and Apps] tisazalay:
The EFS folder is not written by ROMs, etc. it is shipped on the phone by the service provider (it's compiled with individual info like the IMEI, branding, lock state, etc.), so my best bet would be to tell them your phone bricked while charging overnight... with everything wiped that way they'll probably jig it right away. Just give them a phone that doesn't boot and they will probably fix it if it's under warranty. Blame it on the power company. But that's still a risky move... Nevertheless you can keep your phone in this state for ever probably :fingers-crossed:. I was lucky once that I had insurance and someone stole my phone (and probably threw it in a garbage can) so I just reported and got a new one whithout problems. Remember they prefer a happy customer than a shiny phone in stock. Try buying insurance if things start getting worse.

PS: I wouldn't suggest you kill your EFS folder by any reason (even with the appropriate backups) because not a single OTA / Kies / Odin will allow you to make calls without the EFS (probably you would be able only to make calls over wifi but it will cripple your device for the purpose it was first made, a telephone) and imagine not being able to restore the backup... only if you get in that state you should try to restore the backup and if it doesn't work.... then there are the other ways around. Remember also that the nandroid backup from CWM doesn't backup the EFS as far as I know, there are specialized utilities that mess with the EFS, but you can also copy the files with a root explorer)
[Galaxy S III Themes and Apps] spocky12:
This is not a problem and you can consider your phone unlocked because as of now Samsung didn't add the same checks on GS2. Not sure they will. Anyway, if you want to send me your efs backup (you'll find it in sdcard/GalaxSimUnlock), I will add full support.

If you want to improve the chances to recover from an eventual future error, use EFS Pro and backup your current efs folder (tar AND partition img). I might be able to recover your stock nv_core with this info if you need to (did it already, saving somebody from bad/fake imei). I'm planning on adding this functionnality to my app but it would require a lot of time to implement, so it won't be before a few weeks (if ever).
[Galaxy S III Themes and Apps] smohanv:
Thank you very much for your help. Yes, I noticed that CWM backup is not taking copy of efs. Actually I have done factory jig reset few times on my previous samsung products like Galaxy Nexys, SGS II by sending them. I use to forcefully brick it and use to book repair with them (moer or less the same way you mentioned). But, the pain is waiting for two weeks until it comes back. Phone is working so far good and will attempt when I experience issue with the phone. I should do before the warranty expires.

Thanks mate.

Note:

Do you think the one below will resolve the problem,

type *#*#197328640#*#*

then go to COMMON>> and NV REBUILD, wait 5 seconds then reboot phone. This will rebuild ur EFS

I found this somewhere on the net and when i typed the GSM code above I see the screen service mode and do not see any options mentioned above.

I think the above option will work only if I have efs backup. What do you think?

yes you are right ;) we dont know what samsung will do in the final release :confused:

thank you my friend ;)
[Galaxy S III Themes and Apps] spocky12:
Can't say for sure, but the more I understand how efs / nv_data works, the more I believe it's been unlocked the same way an official unlock code would have done, and not much can be done to tell whether it's been hacked or not.

To be more affirmative, I would really benefit having a before/after efs folder from a device unlocked with an official unlock code.
[Galaxy S III Themes and Apps] tisazalay:
I haven't tried that but my guess would be that it restores the EFS from a backup and since the "backup" was changed (with the patched nv_core.bak) used on the other fix, that would be the situation described by other members that might get you corrupted. If you plan to do that have a backup before.... the code is *#197328640# then option 6 (you can touch over it or select by menu), it's the same code used to increase the volume level on the Galaxy Mini. (Option 5 in that case)

I would also suggest you ask for help to Odia or this thread's OP spocky12 and PM them a copy of your EFS folder it's much much much better than to being without your phone for 2 weeks!

Could somebody with a recent jb leak installed send me a tar of their "efs" + new "sprd_efs" folders please ?

Not 100% sure what that new folder is. I saw it in new ril code but didn't take much time to analyse its use...
[Galaxy S III Themes and Apps] jamie2002uk:
Ummm i could send my efs but what do you mean by sprd_efs? I dont have any new folders?
[Galaxy S III Themes and Apps] spocky12:
Mmmm ok...

That's something they added recently in jb rils. I suppose it's not finished so that would explain why I couldn't find where the function was called. It's another efs folder called 'sprd_efs' that is automatically generated if it doesn't exist and that contains some parts of the files present in efs folder. I didn't dig enough to understand what these parts should be.

Anyway, I suppose it will be added soon, so if you could check for this folder in newer rils, that would be great.

Fwiw, I also found multiple references to LTE in last ril, that might be related to the new i9305.
