I get my phone like 3 days ago and when I putted my sim (movistar) didn't work because it says that just accept telcel, then I tried to unlock it but I couldn't so I decided to upload to another rom (the first rom was 2.3.6 gingerbread) so I updated it to 4.1.2 JellyBean (The official one, by KIES) ok then I tried it on it, but it doesn't work nethier, it appeared a padlock and the only option was "Dismiss" then I read on internet that didnt work because I have to use a rom unofficial or I mean... a rom that doesn't belong to Telcel (Because when I turned on the phone always appeared the bootogo of telcel) then I uploaded to Kitkat 4.4.2, nightly, being exactly, this one: cm-11-20140324-NIGHTLY-i9100.zip I downloaded it from the official page of cyanogemod, then I installed. When I turned on the phone after install it It appeared and option like the one before, but this time its allowed me to introduce the unlock code, it said "SIM network unlock PIN" BUT I pressed dismiss, and I searched tutorials for unlock it again, but I couldn't D: all the tutorials I found include Galaxy S Unlock, Galaxy Sim Unlock, but any of the tutorials worked, always I restart my phone appeared that message "SIM network unlock PIN". SO..... what can I do?? D: I'm not sure but some tutorials said that I have to change the rom for another one but I want the one I have right now. Please help me :'(

[Q] Can't unlock- restart before code display.

I cant unlock my Galaxy S2. It is currently locked to Bell and I would like to be using Rogers. I Have already successfully rooted the phone (or so the computer says and the Yellow triangle indicates on the phone. I have downloaded Chainfires Unlock app, but every time the phone gets to 5/5 around 60% the phone just restarts itself without displaying the actual Unlock code. Very annoying. What do? Thanks in advance guys.
That unlock app doesn't work for Bell or Virgin phones, use this one it is confirmed to work. I have personally used it on my Bell phone.
https://market.android.com/details?id=com.helroz.galaxysunlock
Note this one doesn't give a code, it just unlocks the phone.
Im sorry but im clearly not too bright. I have downloaded this app i saved (step one) then I press step 2 (unlock sim) and the phone just restarts. I have busybox latest version installed 1.18.something i believe and I have tried to google a how to for this but cant seem to find one. am i doing something wrong? how do i use this or where can I find a guide? Again sorry and much thanks
It is done then after it rebooted you are sim unlocked.
You can confirm it by putting *#SIMLOCK# into the phone dialer. Everything should say off.

S3 relocked?

I have a factory locked S3, but my provider gives out the unlocking code for free. I put in a sim from another provider, got asked for the code, entered it and it worked.
I then rooted the phone.
However, after a few days I wanted to remove root and reflashed stock firmware with Odin. I searched out the proper file here at xda and flashed it. I then got an error about messaging stopped everytime I booted and searched some more. The solution was to flash with Odin again, but check upgrade bootloader. After that the phone works fine and everything is in place like it was new.
But, my phone has been locked again and my code does not work anymore. I have called my provider (leaving out the root and flashingpart) and they say that if the unlock is not working I must send it to them so they can unlock it.
So I have these questions:
1. Having done what I have done, will TriangleAway + reflashing stock with Odin remove every trace of my "tampering"?
2. What can they do to the phone that I cannot do myself with som advice from xda?
3. How many attempts are there of entering the unlock code? It still asks for a code. I do not get any message about too many tries. But I have must have punched the code more than three times...
I have read that people get their IMEI changed when reflashing, but mine is still original. I can not understand why the operator lock has come back.
Please help!
1) I believe so yes (not sure, I'm new to this forum just what I've read)
2) They can block the IMEI if the phone was lost/stolen
3) I am not sure with Samsung/Android phones but when I was unlocking my mums Nokia C3 it only allowed me to enter a code three times before displaying an error message.
It is not stolen or lost. I have bought it from my operator myself. I talked to them today and there is no block on this phone. It does work with my operators sim, but no other sims.
My question was that they can do to unlock ut that I cannot do myself?

Everything, they are your carrier.
None of us can generate unlock codes for the phone, they can get the unlock codes and make sure it's 100% unlocked

What about the Voodoo sim unlock app ? You'll need root access though. the app has also been removed from the Play Store
The dev's site, you can download and sideload the app from here:

That's not an unlock code though it's just temporary. A factory unlock is permanent (or so it should be)

I spoke to my carrier and they said that there was only one valid code for my IMEI, and that does not work anymore. It did work once, but after reflashing the firmware with Odin, the lock came back and now the code does not work.
Perhaps they just replace the phone with a swap unit? Therefore I ask again, will TriangleAway and reflashing stock remove all traces of rooting/tampering? If not I will get the phone back and be forced to pay for the service as well.
+1 for this problem.
I unlocked mine with the voodoo unlocker and was fine for a couple of months. Flashed a newer version of cm10 and was asked to enter Sim unlock code. This time I got the pin from my carrier but with that number it says Sim unlock unsuccessful.
Anyone else had this problem? Anyone know of a solution?
At the moment I just have a fancy mp3 player/camera :silly:
Voodoo sim doesn't work properly with then latest firmwarea but theres a new app 'Galaxsim-unlock' that I can recommend. Your'llshare find it over in the themes and apps section

You can try to use Valhalla ( Voodoo has disappeared from the Play Store ) :

I've managed to get mine back to unlocked.
I was on cm10 and then when flashing a newer version the lock came back. I was originally using voodoo sim unlock but that wouldnt work this time so rang my carrier and got an official code which would not work either.
Flashed back to stock using odin making sure to use the network branded ROM i was originally on and not just a stock ROM, then enter the code the carrier gave me and this time it worked!
Guessing you must be running a stock carrier branded ROM for the code to register properly and unlock.
Hope this works for anyone else!

[Q] After update to 4.1.2 phone got simlocked and doesnt unlock.

hello everybody
Yesterday my phone asked me to update and i accepted it unfortunately.
I live in France, phone is bought here blocked by SFR operator.
One year ago i got the code to unblock from SFR and I unblocked it and since then i have used FREE, COSMOTE(Greece) and lately i m using BOUYGUES operator.
Problem:
After the update, phone got simlocked again and with my BOUYGUES sim it asks me for a "sim network unlock pin". I insert the code i had but it doesn't unlock it.
I called SFR and fun fact is that they claim that the unlock is permanant (they are not aware of this new issue) and the unlock code unique. I asked them the code to ensure what i had is correct and they confirmed... So code is 100% correct...
Since it was not working they told me to remove any sim card from the phone and do the following steps...
1 click on TELEPHONE icon
2 enter *#46744674 and press #
3 the code should disappear
4 then enter #7465625*638* and press #
5 you will now be prompted to enter the unlock code
6 enter the code NCK and press ok OK.
if code is good, phone gets unlocked
So while step 2-3-4 work fine, the #7465625*638*# disappears but step 5 never happens... There is not screen prompting me to insert the code....
I called Samsung after this and I told them everything i ve tried...
they proposed me to do this --> *#0111*CODE# and it will get unlocked... (super unfriendly french customer service hanged up on me)
I did it but nothing happen.. not even the *#0111*CODE# got disappeared like it happened with steps 2-4 above....
To me it looks like the new android 4.1.2 messed up everything....
Problem seems new... i found two posts in french describing the same problem with no solution but i cant post the links here.
Any ideas how to fix this?
Thanks for reading this
Yeah, root it & unlock it.

Issue in process of rooting the phone - to unlock the phone
Hi,
I have similar problem with my Samsung Galaxy S II SGS2 GT-i9100.
My phone is UNROOTED.
After it was updated from ICS to Jellybean (upgrade via the air, not using Kies and not using Odin), I am also asked for SIM UNLOCK PIN.
The phone was originally bought locked to O2 UK network, then unlocked, but the unlock code used in past does not work now.
The problem is that in all places it says to root the device, and in order to root it, I am advised to create a backup copy of efs folder, and in order to backup the efs folder I need to have root permissions... - deadlock !
In additions, many guides says that in order to root the phone, I need to have only for phones that are SIM FREE, which brings me back to start - I will not be able to flush ROM/Kernel to root it as my phone is SIM locked...
Any suggestions that will help me unlock the phone?
Thanks!

You're very confused.
1) Root your phone. There are multiple methods. Search/read/learn & choose whichever one you think is best for you. The phone does not have to be 'sim-free' or unlocked or anything else in order to root it. As I said, you are clearly confused. You need to search/read/learn & not do anything to your phone until you're no longer confused, or you'll 'break' it.
2) Create an EFS backup using kTool from Google Play. Keep one copy of this backup on your PC, and another copy on the external SD card in your phone if you have one.
3) Unlock the phone with whichever app you want to use to unlock it.
Hello
I found an easy way to root it but i cant post a link... so google "[RESOLU] code deverouillage reseau" and you ll see the thread... (it is in french)
As user "gab34" says, i downloaded the proper zip file (in my case was XWLSD_root.zip) and put it in the sd card as it is (as a zip). (you have to subscribe to let you download the file :/)
Then i pressed up-power-home buttons until it turns off and on again.
Then i was in the recovery meny , and with the volume button i went down to "apply update from external storage" i pressed the power button to enter, chose the file XWLSD_root.zip, press again power button, installation will take place in ../ , press power button, the reboot now and power button.
The phone restarts as rooted and then you can use GALAXSIM to unlock it..
You download Galaxsim unlock for free, then it tells you if it can unlock and if so you pay 3 euros for full version and unlock it....
Try google translator and a french speaker if you need help with the site... It took me 10 minutes to do it...
If not, try to google how to root easily like i did with just a zip file in the sd card...
Hope it helps
Thanks but we kinda know how to do that.
Please don't (try to) post a link from another site, those sites get the info from xda anyway.

Sim Unlock With Custom ROM (P769)

So I installed a custom rom on my phone after unlocking BL and all that a while ago.
I recently got the unlock code from my service provider and was trying to sim unlock the L9. I get an error saying I have an invalid code (which it isn't). A quick google told me that custom roms sometimes won't let you use unlock codes.
I tried using the guide from @cmahendra to reset back to the original kdz/ROM for the phone but it stops at 15% and says phone not connected (even through all the drivers install/are installed correctly).
Does anyone know best way to unlock the phone with the unlock pin provided? Or at least how to reset it back to normal?

GT-I9100 updating to 4.1.2

Hello,
I have a Samsung S2 (GT-I9100), the current android version on it was 4.0.2. Recently i tried to upgrade it to android 4.1.2 (I guess it is the latest supported version for this phone isnt it?).
I tried using Samsung Kies and Odin, but always end up with the phone getting locked (I get that SIM Network Unlock PIN message).
I even tried with the "Samsung S unlock" app, but it failed to unlock it.
However, when i downgraded to 4.0.3, the "Samsung S unlock" app unlocked successfully.
I have tried several things, i called my operator to ask for the PIN (but he had no idea what an "unlock PIN" is and asked me to change my phone instead ... -.-), i even tried to extract the "hash" from my data file, and i tried to crack the hash with hashcat, but it failed. I even tried to dial *#197328640#, and proceed as some tutorials has indicated, but i couldnt go beyond the "PHONE CONTROL" menu.
So i have some questions, im planing on installing cyanogenmod (android 5.1.1), would that removed the lock? (i cant try it now, i dont have the phone on me), like is the lock only for samsungs ROMs? or it is like HARD-CODED in the phone?
Another thing is, i was taking a look at where the lock functionality is located (in the source code), and i think i was able to find it in the "hidden.img" file, in an application called SecPhone.apk (odex), so my question here is, if i somehow was able to bypass this function (like always return true or something) then repack the hidden.img and install the new version, would that work? Or i shouldnt waste my time on that?
(And can anyone provide me with the source code of the Android 4.1.2? its a bit hard and annoying to navigate though the code on the browser, i tried to download it using the google repo tool, was running that under VM (as it only works on linux), and it i didnt have enough space, so it failed, and im a bit to lazzy to re-install the VM ...)
One last thing, while examining the code, i noticed that the unlock function takes 2 parameters, the PUK and the PIN, and only if the PUK is null then that function will use the PIN, so would introducing the PUK as the unlock PIN would work?
Thank you for your time ...
