[HowTo] SIM Unlock when first attempt failed - Galaxy S II Q&A, Help & Troubleshooting

Hi,
SIM Unlocking is handled in Odia's SIM Unlock thread:
http://forum.xda-developers.com/showthread.php?t=1064978
The easiest way is to use Chainfire's "Galaxy S2 SIM Unlock" app.
You can use the following code to check if your device is locked:
*#7465625#
In my case it had only the first "network" lock.
Unfortunately the "Unlock" code provided by the app did not work and the message was "unsuccessful".
Thus I have put the "Unfreeze" code and the message was "unsuccessful" too.
Finally I have put the "Unlock" code again and now the message was "successful".
It looks like some carriers "freeze" their device beforehand, so that "Unfreeze" and "Unlock" codes are necessary.
Happy unlocking.

if you can get the unlock and unfreeze codes THIS WORKS A TREAT
THANKS Im now free of O2

what the heck this method worked for me.. and its O2 i mean it was locked to O2 and i brought it in sweden it gave me unlock code and unfreeze code i tried unlock code like twice without avail and after i used unfreeze code (unsuccessful) i tried unlock code again (unsuccessful) but its unlocked.. now i am confused why did it said unsuccessful but its unlocked .. well why should i whine it worked so you're looking at a happy dude cheers
p.s You got thanks from me buddy d.s

Unlock code on 8525

I unlocked my phone and put in my simcard from T-mobile and the phone says that the network is locked and to put in the unlock code. What the heck is the unlock code. Isn't it usually something easy like 12345.

No, it is not usually easy. If you did unlock your phone, then it would not be locked to the network - that is, after all, the actual definition of unlock.
Try searching on unlock - or just look up at that sticky atop this forum. Good luck.

Which ROM will work with unlock code

Hi all,
I've picked up my unlock code using the super-useful app listed here:
showthread.php?t=761045
However, my phone won't accept the code with presented with a new SIM card.
I'm able to 'relock' the phone using the *7465625*638*# command, so I'm pretty sure the unlock code is correct.
I've tried flashing to the stock rom listed here, but I still get an incorrect PIN error when I try to unlock:
showthread.php?t=740077
So, what ROM have people used to successfully unlock their Tmobile Vibrant?
Thanks in advance!

[Q] Unlock

hi,
I rooted my s2(locked to o2) and installed sim unlock app, after running the app i got the code install. i then turned the phone off and put in my t-mobile sim on boot it ask for the pin, i instered the code i was given and it said invalid code 2 attempts remaining.
I then when to an unlock website inputed the imei number and i was given the same unlock code, i tried it again just in case i had put the code in wrong before, however i still get wrong code 1 atttempt remaining.
can anybody what i am doing wrong and am i correct in saying that if i make 1 more wrong atttempt i have to use the unfreeze code, however i am reluctant to try the sck or spck codes in case the unfreeze code does not work.
Any ideas please

Hi, did you insert the code the app gave you as the PIN number?
You need to enter the SIM cards 4 digit PIN first before you are asked to enter the unlock code.
Sorry if i picked this up wrong, but from reading your post it sounds like that's what you did!
Unlock
Many thanks,

[Q] Sim unlock sgs2

How many attempts are you allowed
Can I find this on my phone
If at max can I reset
My phone is rooted and I ran unlock app the code wouldn't unlock phone
Do I use unfreeze code then try unlock code again
Any help would be much appreciated
Have trolled through the forums point me to a link
Cheers
If you are rooted, use Galaxy_S Unlock from the market.
[root] SGS2 SIM unlock code finder
Or you can use Chainfire's unlock code apk.
I have and the code won't unlock from O2
That is why I'm asking if you only get so many chances

Just a noob who's trying to understand as much as possible before actually doing anything to their new toy.
Reading other threads on this subject suggests that NONE of the routes to unlock documented on this forum (whether via an app or manually using odia's method) will work UNLESS you have hardware version 1.2.
You can find your hardware version by typing *#2222# into the dialler.
My phone is H/W version 1.4 - does this mean there's no way I can unlock it right now without buying an unlock code off the carrier?
Any way to check this on the phone and can it be reset to zero?

I'm curious to know what hardware version you have. Just type *#2222# into the dialler & report back what you see on the screen.
READ FTA HW VERSION
FTA HW VERSION : REV1.4
Hope this helps
Ive also given phone to a "SHOP" to have it unlocked
they couldn't get it unlocked either - this was going to be at a cost £20 - obviously i didnt have to pay
So im pretty sure that more than 3 attempts have been made to unlock phone - all i want to know is can you reset the "attempt counter"

There'll be an unfreeze code you can enter for that but if the methods used here can't find the unlock code, then they almost certainly can't find the unfreeze code either. For H/W v. 1.4, I believe Samsung have salted the encryption of the unlock & unfreeze codes stored in nv_data.bin, so any attempt at unlock based on odia's method will fail.
Hopefully one of the more experienced members will come along soon and help us noob's out, even if it's only to confirm that there's no way of unlocking our phones without paying the carrier for the code.
Phone unlocked :- ran app got unfreeze code put that in shut down phone removed battery(dont think this is necessary) restarted phone then put in unlock code SUCCESS phone now unlocked and all appears to be well.
Just going to thank author of post
MODS ok to close Thread I'm sorted

This worked for me too and I had tried every other method going. my phone was locked to orange and was rev 1.4
I also have HW 1.4.
But I'm not confidence with Helroz method.
I've heard that is different from IMEI method, and I prefer to do it like "buying imei unlock method"
So, is there any option to get unlock code for HW 1.4 ? May be unfreze also ?
I will put manually when the SGS2 asks for it.

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!
