Help!

I'm an experienced use, but am totally lost here.

I got the SIM unlock code from Tmobile yesterday, threw in an ATT sim, unlocked it, no problem.

I thought it was working fine yesterday

Then when I woke up this morning, i have no network at all! Just the circle with a line through it.

Anyone have any thoughts/guesses/help? I don't know what to do!

If anyone has any advice, it would be greatly, greatly appreciated!

Hey fellas,

Any news?

anyone found the nv_data.bin?
[T-Mobile Samsung Galaxy S II SGH-T989] SevenSe7enSeven:
I have a odd story about T-mobile and the unlocking process. on their site it says you can get an unlock code if you pay retail price for a phone. so i did that and submitted the info. i received a e-mail saying they cant send me a code. i called 3 times and i got the same thing.

i went a head and decided to buy one on ebay for $20 3 weeks ago. last week i received a email from tmobile with a unlock code even though they said no.
[T-Mobile Samsung Galaxy S II SGH-T989] Marq221:
No nv_data.bin files

Okay, so here is my issue: no nv_data.bin or md5 files exist in my efs folder. All attempts to unlock my device have failed utterly and completely (even with code). Galaxy_S_Unlocker fails at step one due to not being able to backup my efs folder even though it clearly does. I've even tried some tools online, but the only thing I could get there was a complete IMEI change. That is not going to help my cause much. :P So, after much exploration ive come across some pretty random crypto files and an edk_p file. Question is: does anybody else have this exact problem AND/OR is there a way to rebuild the nv_data files. Backing up the efs and deleting did not bring them about. Couldn't find the so-called ORIGINAL_SHIPPED_EFS folder either.

[T-Mobile Samsung Galaxy S II SGH-T989] sddurand:
I also just successfully used this web service... I didn't see where you entered a promo code so just coughed up the $24.99 USD. The web site stated a 2-24 hour queue time and I had my unlock code in about 4 hours. I'm now unlocked.... One thing i did notice in this process is the method to pull up your IMEI # using the dialer gave me an extra "/03" compared to the IMEI # printed on the sticker behind the battery. I used the printed sticker IMEI and it worked.

Or you can go to a cellphone store and ask them if they could unlock your phone... people usually charge from $10-$20 and its done in 5-10 moutes..

If you guys dont trust buying code from the web.
[T-Mobile Samsung Galaxy S II SGH-T989] Marq221:
While Im sure the posts regarding calling TMobile and\or paying for unlock codes were helpful to some that is not what this specific thread is for. With that said Id like to try and revive this thread. Using DFS i was able to pull a secondary efs folder off of my t989. My problem is that I dont understand many of the files in there. If any devs are interested in helping find a real unlock solution for this phone I can walk you through how to recreate the methods I used to find the files. I believe they may help.
[T-Mobile Samsung Galaxy S II SGH-T989] ignacioxd:
Can you please describe the method you used? I will be unlocking one sometime soon, so I can make a backup of that folder before and then after I unlock to see if something changes.

Yea, what you are going to need is access to some basic browser software on the computer or your phone. By using this software, you go to a site that accepts payments in exchange for an unlock code.

After getting the code, you'll probably need a sim card from another carrier to input it.
[T-Mobile Samsung Galaxy S II SGH-T989] xsteven77x:
You do need another Sim. I tried everyway possible without one and it won't work.

If I may, what version of Android were you on? 2.3.6 or the 2.3.5?

I am currently on 2.3.6 stock and it did not work.

For those following, I was on 2.3.6 on my T-Mobile variant of the S II (SGH-T989).

EDIT: It would appear that the "Z3X" is not really available to the common user. http://z3x-team.com/ Correct me if I am wrong, but it looks fairly pricey too; I'd imagine this might be what those small stores, in a mall or something, would use to unlock one's phone, yes?

I do think I found a possible outlet/venue to dump the NV memory...but we shall see in a few days.

Qualcomm chipsts are fun. For years I downloaded and kept unlocking tools and the like for CDMA/GSM phones. I remember finding on a very very sketchy foreign website several years back -- by pure luck -- a tool called QCAT that was bundled with a new version of QXDM I still never have seen again today (both by Qualcomm). Complete unprohibited access to the device.

Easiest Way to Unlock your Tmo SGS2

Go to tmobile chat and talk to an agent. Tell them your going to Mexico in a few week and require an unlock code for your trip. They will ask you a few account Info questions. Your Email you want it sent to and your IMEI Number..... DONE! You will have your unlock code in a few days..... If you have a tmobile account
[T-Mobile Samsung Galaxy S II SGH-T989] falcon67:
Yes I can confirm it it is locked. Any development is ongoing to unlock.
[T-Mobile Samsung Galaxy S II SGH-T989] tagmwar:
I can also confirm this. At 11 last night I requested my unlock code and by 9am they sent it. As long as your phone is not stolen and just have a T-Mobile account they will send you the code. Told them I was going to Italy for vacation and wanted to use my phone there.
[T-Mobile Samsung Galaxy S II SGH-T989] blatz729:
I called them a couple months into my TMobile plan. I think 2 or 3? I told then I was going to travel to Mexico and if I could have the unlock code. Person gladly gave it to me :-D

[T-Mobile Samsung Galaxy S II SGH-T989] wingtytn:
i brought the phone out right from tmobile and called them a few days later for the unlock code all they did was asked me to fax a copy of my reciept and then they emailed me the unlock code
[T-Mobile Samsung Galaxy S II SGH-T989] nightfall987:
tmo policy

Tmobile usa's policy is and always has been if you buy it at full cost you can fax in the receipt and get the unlock code immediately. If you start a contract with them you must wait 90 days to get the unlock code from them. Its to avoid having people buy the phones at a discount then sell them unlocked to make a profit. I worked for them for years and I know that is still their current policy. After 90 days you dont have to make up any story just ask for the code since you can! Loving this phone!!
[T-Mobile Samsung Galaxy S II SGH-T989] cwbeasley:
It's not 90 days, it's only 40 days after purchase for a discount. If you can prove (receipt) no discount given, it (unlock code) will be given with no problem.

People, please stop passing bad information for what you think you remember!! This thread is way too long.

The software & hardware needed to unlock it yourself is a NSBOX, however I sincerely wish you the best of luck with that. The apps created will not unlock at Samsung Galaxy S II as of the time of this posting, and don't expect that to change, as it's been worked on for awhile now. I am specifically referring to the T-Mobile variant ONLY, the 989 (that should clarify it).

You can, wait 40 days of having the phone on active on the account and call T-Mobile, prove you paid full retail (the $500+ price) and show receipt and call T-Mobile, find someone with a nsbox (usually a store unlocker), or wait until there is a software app solution is found. I don't recommend the unlocking solutions online as there is always the risk of giving your CC# out for something that may or may not be bogus - and there's no recourse for that other than a good fight with your bank that you also may or may not win.

My suggestion? Take it to a physical store. If they unlock it, you win, then you pay. If they don't unlock it, you don't win, and you don't pay.
[T-Mobile Samsung Galaxy S II SGH-T989] cipsaz:
Ok guys, I have an issue.

I received the unlock code from tmobile and used international SIM card to unlock the phone. However, the code is incorrect and I have already tried twice and now only one attempt is left. I've realized that the international SIM card I used has its own code, maybe that's the case?

So what's the trick here? Any way to reset the count? The T989 is rooted.
[T-Mobile Samsung Galaxy S II SGH-T989] Jamar16:
I didn't have any problem unlocking mine, I called them the day after I bought my SGS II on discount and got the unlock code on the 3rd day.

Let T-Mobile know, double check the IMEI you gave them and double check that the code you are entering is correct.

[T-Mobile Samsung Galaxy S II SGH-T989] cipsaz:
Well, everything was correct, but didn't realize the Euro SIM has it's own unlock code, so it had be entered first... Well, I didn't mess with it anyways and just used my friend's ATT sim and worked like a charm.

Feels like unlocking the phone isn't big deal at all now. Used to be a huge pita.

T-mobile Unlock

Here is what i know. If you have the SGS 2 or any t-mobile brand phone, all you have to do is call them up and tell them you need the phone unlocked (You can give them the "am going out of the country" story). Whenever i get a phone upgrade, i call t-mobile for unlock and the next day i get an email with the unlock code. I have never had any problem with t-mobile in regards to unlocking. :cool:
[T-Mobile Samsung Galaxy S II SGH-T989] EnigmaticGeek:
I've done that. I have the physical unlock codes for mine and my wife's phone. The thing is, it would be nice to be able to find where the code is stored too to help people who have bought the phone third party and don't use tmobile without having to call Samsung and pay for it lol

Kind of a just in case type of deal.

Well that and personally my eternal thirst to know things lol

:beer: cheers

[T-Mobile Samsung Galaxy S II SGH-T989] blackangst:
You're assuming the code itself is kept somewhere in the phones version of the registry...it may not be. There may be some other code unlocked when the code is entered and not the code itself. The only way to see is to take two identical phones, one locked one unlocked, and compare each line of code and see what's changed. I would suspect a once unlocked phone would become locked if a different Rom were flashed.

Just throwing that out there.
[T-Mobile Samsung Galaxy S II SGH-T989] EnigmaticGeek:
Your initial theory is something i haven't considered. Hmmm...that's the next direction i will look. You rock!

Second part about it becoming locked after rom flash, that is not the case. I was running stock when i unlocked my phone and have flashed almost every rom (most with a clean flash) and never once locked back up. It's weird

Nva.bin
[T-Mobile Samsung Galaxy S II SGH-T989] fuse1820:
The codes are hiding in the modem EFS and to retrieve them you need to use QPST's file explorer and fetch the file perso.txt. This EFS is different and long forgotten, having been used in the days of BREW CDMA feature phones. Its different than /efs

The problem: the code isn't out there in plain text. Perso.txt is encrypted.

Also it is my theory that unlocking the phone does not cause it to forget its original unlock code. Perso.txt shouldn't change. You can relock your phone using the Personalization.apk dialer codes but the only NCK accepted is the one programed by the factory to unlock the device.

[T-Mobile Samsung Galaxy S II SGH-T989] RA017:
I'm referring to the professional who does phone unlock for a living. I can spend a little money to get an unlock code but I always prefer the fun of doing the unlock myself.

Like the MSMxxxx Qualcomm chip in Galaxy i5500/Gio/Ace, I have a feeling that the code is hidden in the block devices, you should be able to dump it out as text and then search inside for the unlock code which is near the string of 8 zeros. If only I could get my hands on a T989D now I'd love to check it out myself.

---------- Post added at 06:36 PM ---------- Previous post was at 06:30 PM ----------

I've been unlocking Galaxy Gio and Ace before, and in some rare instances, an already unlocked phone will ask for the unlock code again. I cannot say what exactly trigger it but I'm guessing change of sim card. However, the pop up is not the only way to enter the unlock code, you can enter a string of #*#*xxxxxxx*#*# in the dialer to enter the unlock code.
[T-Mobile Samsung Galaxy S II SGH-T989] DriftorX:
So we would need to be on a stock gb or ics for it to work? Stock rooted would be ok?
[T-Mobile Samsung Galaxy S II SGH-T989] blackangst:

[T-Mobile Samsung Galaxy S II SGH-T989] jpjbird:
I am sorry. But I don't understand (Noob) .

Do we need to stay stock or can we root with superuser and it should still allow us to sim unlock when available. Thanks.
[T-Mobile Samsung Galaxy S II SGH-T989] weasel5i2:
Try this..

From what I was able to tell, when I accidentally wiped my IMEI (which subsequently SIM-unlocked my T989 since the IMEI was 0, which corresponds to some kind of test/engineering IMEI from what I've read) - the NV data is stored on one of the many mmcblk0 partitions.

I can't do it now, since ICS (I'm running CM9.1 official) doesn't seem to have the Factory Test mode in the dialer. However, if anyone here still has a T989 running UVKID or other stock(ish) Gingerbread, you can do the following to help us figure it out. Note that it may not work, caveat below.

1) Install "Root Logger" from the Play Store, or better yet, "Root Logger Pro"
(paid) so you can filter out the stuff we're not looking for.

2) Go to the dialer and dial this: *#*#197328640#*#* and it should take you
into the Factory Test menu. Note that it has some quirks with using it: if
you hit <BACK> it will take you out entirely, back to the dialer. You have to
hit <MENU> and navigate around that way, besides touching the on-screen
list of choices.

3) Here's where my memory gets a bit fuzzy. Go to the "COMMON SETTINGS"
(I think) menu, and from there (I think), you should be able to get to another
menu (3 levels deep, maybe?) called "NV BACKUP". Just make damn sure
you don't do the "WIPE NV PARTITION" (I think) option, unless you made a
backup first. That's how I wiped my IMEI. :)

4) Tell it to do a backup. Takes a second, then it should tell you something
in broken English, about success.

5) Now go to Root Logger/Pro, and look to see what commands were run
by the Phone application.

6) Post those commands here for us to nom with our hacker teeth.

CAVEAT: If the system/dialer doesn't use root commands to do its NV backup (i.e., does the NV read/writes directly through the RIL or something) then this will not work. I'm not sure if the dialer even has root access by default. If it does, it's system-explicit and never triggers Superuser..

SMALL NOTE: For the techies, from what I could tell, it backs up the NV data from one partition to another. I couldn't find any file associated with a backup on any user-facing partitions. When I told it to restore the backup which I never made, it said "GOLDEN NV BACKUP PART NOT EXIST" or something like that.

Hope this helps. I'd do it myself, but I'm not sure I can downgrade my T989 back to Gingerbread from ICS. I really need to edit my sig.
