Hex editing to unlock Samsung Galaxy S2 i9100 on t-mobile - Galaxy S II Q&A, Help & Troubleshooting

Hi,
Is there anyone who knows how to Hex edit the nv_data.bin file to unlock (or obtain an unlock code) for my Samsung Galaxy S2. I would really appreciate it if I could send you my file.
(I have already tried all the unlocking apps and they dont work. I have also been looking online all day and I came accross some sites that go on about hex editing and "hashes". I am a really amatuer hex editor so dont have any clue what these "hashes" are, or where to find them)
Thankyou

Root your phone and then just download the Galaxy S_unlock app by helroz on market, this will patch the nv_data.bin file and you will be unlocked

based on your nv_data.bin it doesn't show any locks, all are zeros. are you sure its locked?

hi guys!! i have problems unlocking my sgs2 T-Mobile...i tried almost everything... chainfire sgs2 unlock..galaxy_s unlock app... i try to modify nv_data..
here is my situation.. chainfire can't find unlock code.. galaxy_s unlock app unlock phone and when i restart it it is locked again.. and i just run step 2 in galaxy_s unlock app and it's unlocked again until i restart phone...

[Q] Sim unlock sgs2

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.

[Q] Unlocking Samsung Galaxy W T679M

Hey guys,
I just wanted to find out if anybody can help me out with unlocking my Samsung Galaxy W T679M. I have followed ALL of the methods on this site but seem to have trouble finding the nv_data.bin file and the efs folder. Anytime I attempt to do anything with these files in adb or in terminal it comes up file not found.
I tried to unlock it remotely by paying for the code with two different sites and both responded with saying my phone is unlockable and to either contact the carrier or unlock via cable.
Is there any software to do this via cable? Or is the missing nv_data.bin file actually findable? I also couldnt find the bml5.img file via terminal and adb.
Could someone please help me or point me in the right direction? Apologies if this is the wrong place to ask.
Not Unlocked Too.

[Q] Sim Unlock Codes - How?

Let me just start off by saying I have tried everything (free) under the sun to unlock my S3 (I9300). I have learnt more in the last 2 days about my phone than I have in the past 2 years of owning it. From rooting and trying unlock apps to downgrading and trying the service mode glitch, I've tried it. It is more of a quest at this point. I would have paid to unlock it by now if it wasn't for my stubbornness.
From what I understand, since I am on version 4.3 and have EFS v2 (with no EFS v1 backup), there is no way to network unlock my phone without getting an unlock code from my network or a website, both of which require payment.
I can understand how the network is able to get an unlock code but what I don't understand is how various websites can 'calculate' unlock codes for my device, especially without the device at hand.
In theory, why can't I calculate the unlock codes myself? If I can, how?
No, codes aren't calculated -they come from a database that you can't access. Give up and buy a code.

I actually have the codes that Vodafone provides free of charge with it's Network unlocking tool, unfortunately these codes don't work and they have yet to give me a reason why. The only thing I can hope for is a way to flash back to efs v1 but so far as I know it's impossible.

Is there a way to unlock the Galaxy Light to use on another Carrier manualy?

I bought a sgh-t399n at a garage sale recently and quickly rooted the phone and installed TWRP Recovery and CM12 on it. I called Metro and T-Mobile ( After flashing their firmware) for the unlock code but of course they refused to give it to me. So i tried 2 or 3 different unlock by IMEI websites as well as every single unlock app and software I could find while running logcat. The best lead I've gotten was the S.G.S. Unlock Tool app. It says it found the code but the results are null. In the logcat the system denies permission saying that the app was sending request as -2 when it was 0 and that it needed "android.permission.INTERACT_ACROSS_USERS_FULL" to accsess the info. Now I'm not a Dev by any definition of the term, nor am I any kind of hacker but I have learned a good bit from these forums over the last couple of years and my gut tells me this can be done with a little patients and some help from the good folks at XDA. Any imput on the subject is greatly appreciated.
You won't be able to unlock on CM12, have to have the stock firmware and OS installed.
yeah install stock system and any code should work without issue
If you unlock on stock system and then flash cyanogen, will it be fine?

The unlock code must be hidden on one of the partitions of the device it's self though right? Possibly in the EFS partion? Also how would i change thepermissions of an app to allow in to interact acroo all users?
Whether or not the code is in EFS, you still can't unlock on CM.
No I understand that. It is currently on the T-Mobile stock T399 firmware flashed with odin but still could not get an unlock code . Also i would like to learn to unlock these phones for future devices.
So it is not requesting an unlock code when you have a non T-Mobile SIM card installed? How odd... It should. If not, either it's already unlocked, or something else is going on. Have you tried both the Metro and Tmo firmware? Only the newest T-Mobile and Metro phones are not supported by unlocking via code as they use the Unlock app. As far as unlocking yourself, your best bet would be to get an unlock box like z3x or Octopus if you plan on doing a lot of them. If it's just 1 every year or 2, then it wouldn't make sense. Some phones have ways to unlock via root and hacks, but not all and it is becoming less common now as more manufacturers are making the ways to unlock more difficult either via encryption or other means.
The unlock companies I tried were unable to get a code by imei. Therefore I was never able to put in a real code. I've looked in to the z3x but it is way outta my price range as I am only a novice tinker. I just figured since the code must be in the programing of the phone somewhere then it was just a matter of locating the partition and file in which it was hidden and then decoding it. Is it possible to change an apps or users permissions? If so how?

I believe the app Root explorer allows you to change permissions on items.
It does, but nothing Root Explorer can do will help you find an unlock code, unfortunately. If the phone does not ask for a code when inserting another carrier's SIM, then that's the issue that would need to be resolved before anything else.
Sorry if I've been unclear. The phone dose ask for a code when a sim from a different carrier is put in but after trying 3 unlock by IMEI companies none of them were able to generate a code by IMEI. As for the permissions issue, I have an app that claims to find the codes but only says "null" in the results column. After going through the log cat it says the app is running as user 0 but is requesting info as user -2 and that it needs the permission " INTERACT_ACROSS_USERS_FULL" to show the info. So i was hoping to learn how i grant said app that permission and see if it would show the code?

Could anyone PLEASE PLEASE PLEASE PLEASE PLEASE give me a working unlock code for my metro pcs phone email me [email protected] or [email protected] thank you.
Running into the same problem only im on a non rooted system. I need a solution to get the codes needed to unlock it from T-mobile and need them without running hardware as all i have is hardware from the old days. Software would be a choice if anyone knows of anything reliable. Services I am also willing to pay for if cheap and working.
