[APP] GalaxSim Unlock 1.02, JB compatible

im running cm10.1 on a i9300, the app says that can be unlocked, then when i try to unlock everything is fine, and says that is unlocked, but when i reboot im still getting the network pin request... i've tried with the pro version and the full version for xda....
Hello,
I used the tool attached in this thread on my GSII (GT-I9100IKAIDE). I did a backup of my EFS folder first (now i know I did it the wrong way, cause I just copied the folder, losing permissions, but still it's better than nothing), also this tool itself did a proper .tar backup. After rebooting (still without SIM) it said that the phone is now unlocked, but I lost my IMEI, it's empty. I am on stock 4.0.4 rom with root installed with this method (1st one, superSU with busybox). After I saw no IMEI, I panicked a bit, and instantly did "restore EFS". I rebooted, and yeah, the phone got relocked, but still no IMEI. So, to sum up, I have 2 backups, so I should be pretty safe, but I still can't bring my phone's IMEI back (SIM Unlock is now not my priority, just want to get the IMEI back). Anyone could help?
Edit:
Turned out to be the phone problem. It was already once sent under warranty, they claimed to "fix" it, but they didn't apparently. Will have to use a bit more pressure on them this time as they kept it for almost 4 months (sick!) and still didn't do a thing. It is totally unrelated to this tool. If anyone else feels he "tried everything" just try taking out the battery, waiting for 10 seconds or so, putting it back and powering the phone. For a random amount of time it will come back to showing the right IMEI, network and everything (SIM unlock worked as well BTW). It's just ****ty Samsung quality that makes it go network dead after random amount of time (always under an hour though).

Thanks for answer. I used XDA since HTC Artemis and always loved the community here. It's such an awesome thing that I never really needed to register here (until now) since all my questions were always answered somewhere (I DO now how to use search function and how to read, read and read
). See my updated post, unfortunately even XDA can't deal with manufacturing faults... BTW:
I still have my HTC Artemis working... Galaxy S2 spent more time in repair than in use... I think that does say a bit about the build quality...
You probably did once already that is why you can't backup. .....look in your files under galaxsim unlock there will be your efs backup. ......then make little note on wich rom you made this backup. ....look for efs backup. tar

I will not agree with you on that. .....Samsung device are little more complicated than the rest. ......so to my knowledge I run on helping ....if you use cwm recovery do twice all tasks you usually do for fresh install. .....TWRP is something else ....that none of them are perfect. ....so you as human are in control to watch for problems

You know, the thing is, that the phone was brand new (no xda-work done to it) and it was losing signal, IMEI, and all the network info in settings. It is really a hardware fault, as in the warranty card for the first repair they wrote "motherboard fixed" (not replaced unfortunately). If it was "fixable" by xda, how would you explain its current behavior (actually same as before the "repair"): You turn it on, everything is nice and great. After, say, 20 minutes network goes dead and no imei (without touching the phone!). If you reboot it, it's still down. You have to take out the batterry for it to work for some time. Just google "galaxy s2 losing signal" or "galaxy s2 service unavailable". It's really just low quality hardware.
I'm sorry for you having this type of problems. .....so if motherboard is going bad. ....your only choice is warranty ......

Strange query
We I think my phone is now unlocked. Phone (S2) was locked to 3 network orignally
The app shows it as unlocked anlocked now and T-Mobile sim and an orange sim both worked.
However my pay monthly Orange sim is not recognised (says network not found), but the same sim works in my other S2 and other family phones!
Does nayone have any ideas on what I can do to rectify?
Also, I think I paid for this software twice, first time I 'unlocked' it obvisoult processed payment, but when my Orange sim didn't work I reverted back the lock to try another tool and accidentally clicked 'unlock my phone' on this app again. So will I get charged twice and can I get refund for one payment please developer - thanks
Thanks in advance.

411Back in business ! With an app to sim unlock your Galaxy S / S2 / S3 (and variants) (to use any other network operator).
A little background first. I bought my GS3 2 monthes ago. It was sim locked, but I didn't care as I read there was an app to unlock it. Unfortunately, what I didn't know at that time is that this method was not behaving the same way as official sim unlock method. And as you might know, sometime in July, starting from LG6 rom, Samsung added checks to prevent unofficial lock methods, that would relock your device upon each reboot. It looks like they recently did the same on GS2. So I took my favorite decompiler and started looking for a workaround. And here it is : "GalaxSim Unlock".
Now I won't lie to you. I won't tell you it will unlock your phone forever, as I can't say for sure. I won't enter into technical details, but I can't affirm that this app makes all the changes made with buying an official unlock code (at least, not yet). Why ? Because I honestly don't know what those changes are. So Samsung might add some checks in future roms that could probably relock the phone. Or they won't.
With my growing experience of Samsung's EFS, it seems however that they might not do more than my app, in other words, I'm starting to believe that this patch will still work in the future.
One thing for sure : as of now, this app does more than any other manual or automatic methods available, so your device won't relock with any currently available roms (post lg6, Jb leaks...).
So apart from buying an official code, that's probably your best chance to unlock your device for now.
*** FAQ ***
This app will :
- unlock/unbrand your phone the best as my current knowledge permits to. Which is sufficient to run any currently available roms (including JB).
- work on any existing rooted rom
- support international Galaxy S3 i9300 (Us qualcomm based GS3 are not supported at this time)
- support other Galaxy family devices (S, S2 and their variant) (not extensively tested as of now, drop me a pm if yours is unsupported or supported but not written so)
- work if you previously unlocked your device with "voodoo unlock" or "galaxy s unlock"
- work if you installed a previous ril (aka mike's patch).
- warn you if you're using other dangerous methods
- warn you if your imei has been lost due to any error in nv_data caused by a third party app.
- give you detailed information about current locks status (be it locked, unlocked or "partially locked", ie unlocked with methods not compatible with newer roms)
- backup efs before modifying anything (that should guarantee you a safe use)
- enable you to restore your efs backup if you want to.
- be updated when needed (I need it as much as you )
- compute md5 files properly (no log hack)
- support more galaxy devices soon
This app won't :
- Restore your previously lost efs/nv_data/imei or any other magical stuff.
- Support non samsung phones
*** Download ***
GalaxSim Unlock is now available in the Google Play Store here. It's free to download, with in-app billing to unlock, for what I believe is a fair price (I've made it that way so that people can see if GalaxSim Unlock is able to sim unlock their phone before buying).
Other features (device/lock information, nv error detection, efs backup/restore, efs export to a safe place like gmail or google drive) are free to use.
* Temporalily removed the xda version until more tests have been made and a new beta is released. *
In any case, I'd appreciate if you could rate the app on the Play Store.
*** How to use ***
Prerequisites :
- Rooted rom
- Busybox (found on the market and already present in many custom roms)
Install the app, click on "unlock" and reboot.
If it worked successfully and you want to encourage my work (either by supporting more devices or by improving the unlock in case of samsung new ril update) a small donation is appreciated.
Recommendations :
- Even if this app makes a backup of your efs folder, you might want to make one yourself before using it (better safe that sorry)
- Don't delete /sdcard/GalaxSimUnlock/ folder, it contains the efs backup made by the app.
- You can use it with mike's fix libsec-ril.so, no need to restore another ril before unlocking. However, after your phone has been unlocked with this app, I recommend reverting to the ril provided with your rom / adapted to your radio so that the device's functions as expected.
- You can use it on a device previously unlocked with "voodoo unlock" or "galaxy s unlock". However, if possible, restore a stock efs (or uninstall any other previous patches). It's not necessary, but this way, the efs backup made by the app will be clean. And restoring this backup will revert to what your phone was in its initial state, not an intermediate state.
- However you need your .nv_core.bak/md5 (not one from another device found on the web). This is required because using nv_core (or nv_data.bak for the record) coming from another device is dangerous as you might lose your imei anytime in the future if your original nv_data.bin file gets corrupted.
What I would do coming from a previous unlock patch : restore efs, reboot (optionnal but recommended to verify efs has been correctly restored), unlock with the app, restore libsec-ril if needed (manually or by reflashing the rom)
*** Changelog ***
v1.02 (2012-08-24) :
- improved error messages
- added a check for busybox
- modified some checks for more safety
- added full product code string
- updated supported models (and the warning on untested models is not blocking anymore. Although you should be safe thanks to efs backup, USE IT AT YOUR OWN RISKS)
- added a "efs backup" button even if there was an error during prerequisite checks so that you can send me your efs if you want me to have a look at it.
- cosmetic changes
*** Contact ***
Dont hesitate to contact me if you :
- want to buy me a beer
- encounter a bug
- have any suggestion concerning GalaxSim Unlock
- have unlocked your device with an official unlock code and want to send me your efs folder so that I can improve this app.
- have any kind of information concerning nv_data that I should be aware of (Odia, if you read me... )
*** Credits ***
This app couldn't have been made without the work of a lot of people before me, starting on galaxy s up to latest samsung devices : dawen, Helroz, and NWolf, txlibre, dagentooboy, Odia... (if you feel somebody should be added here, drop me a pm).
Also a big thanks to beta testers : Mopral, Pyr0x64, tisazalay, balviforever, mabmed, OXINARF, xdafann, asphaeris, SweetthD3ViL
Last but not least, donators : Pyr0x64, superfloup, Adrian l., Pacoraban, Rudigus (5 donators for more than 5k downloads... Positive point : I guess my conversion rate could hardly decrease. Edit : well, seems that it did nonetheless )
*** Disclaimer ***
As always, use with caution, I made my best to build something safe to use, but if anything goes wrong please don't burn my house
*** Legal notes ***
YOU MAY NOT USE THIS APPLICATION FOR COMMERCIAL PURPOSES.
Wow, you read it till the end ! Congrats, now go unlocking your device6
I added a few checks and cosmetic changes but the functionnalities are exactly the same. So you don't need to update.5
Could you also check your serial number ? If it has been reset, your device won't connect to network. I can fix it though.
Anyway I4m not sure you read the right section of the faq : a hardlocked device will still request a sim unlock code. If yours doesn't, please have a look at the "no network connection" section in the faq.
Hi, thanks for the feedback !
Due to law changes in the US, I had to temporarily remove GSU from the play store. Hopefully the expected revert of the law will be made soon.33I 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).
