Unlock with code

I have a Samsung Galaxy S2. When I firs bought my phone, i rooted it and then i unlock it with Galaxy s unlock tool from google play. When i updated the firmware, i've lost the sim unlock and when i tried to unlock it again with this tool it never worked. I tried all the tools from google play with no luck. So i searched for a web service that provides unlock codes and found this site: free-my-phone dot com. The code worked like a charm and my samsung it never relocked again. The only thing is that i had to reflash the original firmware in order for the code to work.

My sgs2 was sim unlocked for like 2years or some but after flashing the cyanogenmod 12.1 rom it's not unlocked anymore and I don't really know why if anybody could help me out it'll be gladly appreciatte.

How to unlock the sim while running the rom 5.1.1 cyanogenmod12.1 unofficial cocked by lysergic acid?
[Galaxy S II Themes and Apps] Youdoofus:
I think you need to be on a touchwiz ROM in order to access the menus you need to be in to unlock it. Also you need to be on the right baseband too. So put it back on the right ROM, right baseband, unlock then ROM to whatever flavor of cm you like

Hi Super genious,

I have a Samsung Galaxy GT-i9100 bought at Vodafone Spain that was working with other Vodafone SIM cards but when i tried to use a sim from a different network i go the message "please enter the Network code followed by "unlock".

I have followed the instructions to root my phone (root done and working), then installed and followed the instructions of chainfire to get my unlocking code but i hadn´t had any luck, says "sorry Sim code not found :( ". I runned the software several times with Sim card insert and without it and same results. I´m able to get the unfreeze code though.

The strangest thing is that Vodafone had provided me the unlock code but its not working, appears message as "incorrect code" and for having the phone revised I must pay ( which i don´t want to :) ).

I´m running official android version 4.1.2 .

In despire i Had made a backup of my EFS folder and tried Hellroz method but right when the software says that phone is unlock appears on background the message "insert network code" and phone still locked.

I have restored the EFS folder but running out of ideas.

any tip?

thanks in advance for your comments,

Doesnt work for me. No unfreeze or unlock code either. Can u help me some way? I tried all the methods i could use, like galaxy s unlocker, this sgs2 unlock and a gscript one.

Thanks dude, this stuff is useful for a lot of people.

What do you think? Is this app compatible with Samsung Galaxy Ace, or Can you create an app for Aces which finds the unlock code?

I think SGA uses the same lock method.... because It's Samsung and has android OS. Tell me if I'm wrong....

hello,

I bought a SGS2 from a friend, assumed it would be unlocked but it appears to be locked to 3, I'm on T-Mobile.

I get to a screen that says 'enter Network lock control key' and I enter the 8 digit code gained from this app. And i get 'network unlock request was unsuccessful'.

I've tried using a paid code and now this to no avail, am I going to get a different code using Odias method? (I have no idea how to do various things in that method) or am I screwed?

Does installing new roms get rid of the lock?

[Galaxy S II Themes and Apps] jb14:
Hi all may i beg a bit of advice regarding the sim unlock process

I bought a SGS2 off ebay that was ment to be O2 locked. I am on O2 and coming off a HTC HD2. Anyway I have rooted the galaxy s2 with lite'ning mod v1.2 which is all good. Now when connecting to keis 2 the firmware version comes up as PDA:KE7:PHONE:KDJ/CSC:KD1 (CPW)

Does this mean the phone is locked to the carphone warehouse and not O2?

When i run the sim unlock it is v quick and gives a code of multiple 00000s then nothing. I am stuck on EDGE until I can sort this. I am nervous about trying the code again regarding the warnings! Any help much appreciated

EDIT: I'll repost this elsewhere as the problem may be more than just a sim lock. Thanks

I realised that it didn't worked because my SGSII was unlocked directly from the manufacturer, although I purchased it through Vodafone Spain.

BTW, I'm gonna install this app in a friend's SGSII. Can I remove it once the process is completed or will it lock the sim again?.

Got a SGS2 locked to O2 UK and the code provided is invalid. What should I try now? I did try app with a different network sim, which obviously was blocked before unlocking and because it didn't work it's still blocked

Hi,

I was just wondering, is there a way to re-enable the lock after using this app? Say I wanted to re-lock the phone to O2 OK for whatever reason, like warranty, what would i need to do?
[Galaxy S II Themes and Apps] maddogglucky:
works great .......thanks
[Galaxy S II Themes and Apps] Chainfire:
You don't. You can't. If you want to return it for warranty, unroot it by flashing a full stock firmware and use a JIG to reset the flash counter. The SIM will remain unlocked, but that's perfectly normal. You can buy unlock codes all over the net, and you can even get them from your carrier directly. There's nothing weird about having your phone SIM unlocked.

Not sure if anyone can answer this. Has anyone tried this on 3 Ireland?

I'm bidding on an SGSII thats locked to 3, on the premise that this unlock will work.

If not, i'm guessing I'll have to get a turbo sim or something for it
[Galaxy S II Themes and Apps] evildave_666:
IMPORTANT - new phones using nonzero salt in nv_data.bin

Sorry, I don't have enough post count to post this in development group.

NTT DoCoMo released the Galaxy S II today here in Japan.

Rooted, but the app did nothing but overheat the phone.

I pulled the nv_data.bin file and there were hashes in the right places BUT they appear to use a nonzero salt now.

Using the *#7465625# code my phone only has a network lock and the other 3 (SUB/SP/CP) are off.

Looking at the hex data for the hashes corresponding to the "off" locks, they are

0018148eh: E3 6E 44 B1 BA 6E 7E 9E E6 3C 16 FD 59 80 4A E3

0018149eh: 8E 6A B0 99

(This is SUB lock, but the offset for SP/CP also have the same hashes)

Presumably there is a new salt that will hash 00000000 to this value. Hopefully it is not individual to every phone. I presume a bruteforce attack on the salt is infeasible, even though the hash and the code (00000000) are assumed to be known since the salt keyspace of 2^256 is too large (my engineer coctail-napkin math guess is (2^225)/2 seconds average, or a 61-digit number of years, average solve time based on 2 billion hashes/second).

I am pasting the block of hex here so you can see it (can provide the whole file if needed):

I can confirm that this app works for Network three (3) branded phones as no one seems to know/talk about three phones.

My phone is rooted with Lightning was locked on three i had to ftp this app over through usb into my downloads folder then use my home wifi to go on andriod app market and download astro explorer free, from there i installed the app and ran it.

I'm also getting SIM unlock code found Code: 00000000.

Does this mean I'm not sim locked? I noticed a couple of other people had the same thing but nobody seemed to be able to confirm what this actually MEANS? I got the phone on contract O2 UK which everyone else seems to think is sim locked, so I'm not sure that I'm lucky enough to be sim unlocked. So, can anyone actually confirm what this means? The app isn't working?
[Galaxy S II Themes and Apps] Chainfire:
It is possible it cannot detect the code, you could try Odia's manual method. It is likely it is unlocked though. Try a non-O2 SIM and see if it works.
[Galaxy S II Themes and Apps] diliff:
I tried putting a Vodafone sim from a friend's blackberry in my phone and it appeared to work, it didn't say the sim was blocked. It brought up signal bars but no data - just GSM. When I held the power button, it said data network mode disabled and when I enabled it, still no data services. So I'm not sure if this is because blackberries have different data services or it was somehow locked down on my phone, but certainly didn't seem to have a sim lock to O2. Which is strange, why would some O2 Galaxy S2's be sim locked and others not?
[Galaxy S II Themes and Apps] Chainfire:
BlackBerry's are sometimes set up differently, and you may need a special APN for data to function. Just test if you can _make_ a call.

As for why some are locked and others not... who knows. Carriers are crazy.

Cannot unlock my Galaxy S II :-( - Help please...

Hello and thanks in advance for anyone willing to help.

I just got a Galaxy 2 on T Mobile in the UK which I need to use on Vodafone. I have read the guides and carefully used Odin and the SuperClick to Root my phone. This appeared to work absolutely fine.

I downloaded the app from MarketPlace and ran it no problems, it gave me an 8 digit code 736*****.

I put the Voda SIM in my phone and on reboot it asked me to "Enter Network Lock Control Key", so I carefully entered the 8 digit code and hit unlock. It came back with an unlock unsuccessful message.

I'm trying to be patient and not do anything silly. Could someone please help me by advising what I should do next. Very grateful in advance.

[Galaxy S II Themes and Apps] Chainfire:
You are going to need to try Odia's manual method, and see if any different codes come out.

Unfortunately the code produced is not the right one 100% of the time. Odia's manual method will let you find several possible codes.

Didn't worked for me.

I rooted my SGS2 and after that I used the SGS2 SIM unlock code finder. It successfuly gave me a number of 8 digits.

Restarted the phone with a different carrier Sim card. Entered the PIN of the SIM and after I am asked to enter the Sim unlock code. To my surprize, the code didn't worked. I also restarted the phone(as suggested) but no success in unlocking.

I didn't tried again as you suggested(Thanks for that).

The solution in my case it was to follow an older link, which I used for my Galaxy Tab:

http://xdaforums.com/showthread.php?t=843323

This one, it worked and I managed to unlock my phone.

I would like to mention that for rooting I used : Odin3-v1.85, XWKDD_insecure, which were neccesary for SuperOneClickv1.5.5-ShortFuse.

I wanted to let you know, about my experience, hoping that other people will still manage to unlock their device in cases were the unlock code provided by your app is not working.

Help!

I successfully unlocked my phone a few weeks back, using Chainfire's instructions above. My phone is a 3, now using an Orange simm.

Unfortunately, today I allowed KIES to make a firmware update on the phone. Doh! Now the handset appears to be de-rooted and re-locked. Although I still have the original unlock and unfreeze codes, I cannot seem to get the phone to ask for them.

Has anyone been through this firmware update and had the same result? How do I get the phone to ask for the un-lock code now?

:(

Doh#2!

After 2hrs & ten reboots, the phone started working with two other non-3 Simm cards (Orange PAYG, Russian Beeline), but my usual Orange one still gave "no service". Thus it hadn't relocked. After about another half hour with the SGS2 switched on, the Orange simm began to work again. No idea why it behaved like that....

Hi all. Would appreciate any advice or help on this.

Got my GS II carrier locked from Philippines ( Network locked only) a week ago. Successfully rooted with CF-Root and tried The GS II unlocker ( Thanks to CHAINFIRE ). 2 attempts on the unlock code come out with no code. Same thing happened with the freeze code. IT says no code found. Downloaded Astro and did some browsing on the files, to my surprise there was no nv_data.bin at all under efs folder. The folder contains nothing. Is it possible that the carrier hid/locked away this file? i came up with a conclusion that without the presence of this file, the sgs unlocker would not work and i could not copy this file and do a manual extraction of the code. Tried Terminal Emu to copy it into internal SD, "no file found" !!!

Any idea guys?

BTW Busybox app did not appear on my Phone nor could i access it.

Same here.

Got an S2 from Virgin Mobile (Canada) today, and I can't seem to get it SIM unlocked.

Model: GT-I9100M

Android: 2.3.3

Baseband: I9100MUGKG2

I (think I) rooted the phone just fine as per Chainfire's CF-Root thread, using the firmware CF-Root-SGS2_ZS_OZS_KG2-v4.1-CWM4. I can su in the terminal emulator.

SIM unlock code app fails, taking ~30 minutes each time.

Trying Odia's nv_data.bin method yielded a hash of 28B573822FB84A5F44CC8F8A3804A3C265DE5AE8, but ighashgpu.exe didn't find a password (says CURPWD: DONE:00.90%...). I tried couple of other hash/pass combinations posted in Odia's how-to thread and was able to crack them just fine, so I don't think it's a problem with the brute forcer.

I read that the new scheme might be a hash with a salt based on each phone's UNID, but I thought that was for I9100T models.

Any ideas?
