Where are you find this 6$ unlock? Please let me know.

Ebay?
[T-Mobile Samsung Galaxy S II SGH-T989] digikid:
I installed root logger and ran the nv backup command. It looks like it's talking through the RIL directly as when I looked at the log, there was nothing but the startup commands for root logger. If I remember right, when the G2/Vizion/Desire Z was cracked open they also got into the radio to unlock the sim. That was done by overflowing the kernels write protection over the radio partition, then sending AT@ commands to the radio to set the simlock. Would that sort of thing be possible with our phone?

Oh and as a note, I am rooted using the Jedi Knight rom.
[T-Mobile Samsung Galaxy S II SGH-T989] RA017:
Thanks for your work, did you realize where the backup of nv is stored? Any time stamp chnages on the mmcblk0x devices?
[T-Mobile Samsung Galaxy S II SGH-T989] 8c0re8:
Well i just sent an email to tmobile requesting unlock code...been with them forever so im hoping that they will just give it over no questions asked:silly:
[T-Mobile Samsung Galaxy S II SGH-T989] digikid:
No, log cat isn't giving me any information on where it was stored and I can't figure out how to get into the mmcblk's to check timestamps on files.

ETA: Just got an idea. we can list out all partitions on the phone with 'cat proc/partitions' right? So why not take an image of all of the unknown ones and figure out what's on them? I kinda remember how to grab the images, but don't know how to look in them when they are backed up as they will be in raw format.
[T-Mobile Samsung Galaxy S II SGH-T989] RA017:
Your thoughts are with me. I'm also thinking of searching all the raw devices in the /dev/block directory to see if I can search any unlock code (in plain text with luck), just like how the Galaxy Gio/Ace unlocks are done. (http://xdaforums.com/showthread.php?t=1335548)

Since the Galaxy Gio/Ace devices are using Qualcomm Snapdragon S1 chip (MSM7227) and the T989D is using the Snapdragon S2 chip (MSM8225) which both have integrated radio, I hope that they bear some kind of similarity.

FYI, you just need to do a "cat /dev/block/xxxxx > /sdcard/xxxxx.txt" to dump the file out and then use a hex editor to search inside. Don't try to dump file with "dd" command or attempt to mount the raw device. People reported bricked phones with these.

My T989D is arriving in a few days so I'll try to search too.
[T-Mobile Samsung Galaxy S II SGH-T989] digikid:
:highfive: Glad we're on the same train. I will do that tomorrow and see what I can find out.
[T-Mobile Samsung Galaxy S II SGH-T989] mintharis:
Is there any way I can help?

I'm able to follow what you want to do (output the contents of the dev/block dir to text files, then open each file and look for something), but I don't know what to look for. I'm on a rooted t989d running aokp... don't think that would matter though. Currently locked to Telus.

I could also dump the files and post them if you'd like. Let me know.

Not that I am rushing the process but does anyone have a realistic time line on when the mysteries of this phone are unlocked to unlock it? :) I know timing is all relative so how about a worst circumstance scenario vs a best circumstance scenario? :) Reason is I have 2 business days left to unlock my phone to test on my network to make sure it's all good before I can return it for another one. If there is something wrong after I will have to deal with Samsung directly.

I just did a live chat with tmo about getting unlock codes for both my tmo S2s. Expect email in about 24 hours if they have the codes. 14 days if they have to send it to Samsung to get them.

Edit: Just got my unlock codes email. the usual stuff. Successfully unlocked my stock SGS2. Question on my rom flashed SGS2. its using aokp jb from whitehawkx. Will the unlock work with the flashed rom? or will i have to flash my phone back to stock?

3. Click/Tap in the empty field above the "Unlock & Dismiss" options (this will display a key pad on the screen).

4. Using the key pad input the Unlock Code provided by T-Mobile.

5. Press the Back button to remove the keyboard from screen.

6. Click/Tap the "Unlock" option; handset should display "Network Unlock Successful".

Sorry to be dredging up older posts but this development path would seem to be linked reasonably closely to IMEI repair. I somehow zeroed my IMEI on my device and though it hasn't affected my functionality so far as I can tell I would like to repair it.

Can someone with root try this https://market.android.com/details?id=com.helroz.galaxysunlock

Some comments said this worked when sgs sim unlock did not for them... it says need busy box and root!

FYI- I returned my two I got on launch because I need sim unlock to use, and both had vertical lines otherwise I would be testing myself. As soon as I can find sim unlock right back to buy 2 I want SGS2 bad!:(

Yeah, while this does work for existing customers...Its the people like me that dont use Tmo at all but want the SGS2 that I'm trying to get help for.

TMo rep told me if I don't have an account then they cant help me as they need a TMO phone number to associate the process with for the system. My local service provider uses TMO bands and I have a killer plan for greater than 10 years loyalty, so I'm not going anywhere.

Edit: I did send in my sales receipt for the sim unlock on 10/12 2pm and they said it could take up to 14 days...We all know that is bullcrap and they can do it as they see fit, so I take it as them not willing to do it.

None of the unlock apps from market work. Galaxy_S Unlock from Helroz works on International version of SGS2, but fails on T-mobile SGS2 (T989) with "busybox not installed" error. Yes, I do have root and busybox installed and tested to work.

From adb shell I noticed T-mobile SGS2 does not have nv_data.bin file in /efs or anywhere else. Unix find command could not locate nv_data.bin file.

Try calling tmo through 611. Then in the automated menu say technical support, then agent. Not sure about TMOS policy is on unlocking, but for me I the past they were ok with doing the unlock if you were traveling. Just plan in 24h to get the code.

What Q&A section?
[T-Mobile Samsung Galaxy S II SGH-T989] ssiddiqi1:
Why Q&A?

I am not asking how to simply unlock or get a code from TMO. My question was addressed to developers that TMO-SGS II has no nv_data.bin under /efs. Dev used nv_data.bin on other model to SIM lock SGS2.

It was nota general Q&A chat question. Moving it to general Q&A section is a waste.

I am out of here.... better think, read the post properly then move.
[T-Mobile Samsung Galaxy S II SGH-T989] AllGamer:
to begin with, we don't have a QA section yet

and only actual development are allowed in the DEV section

that aside, i'm also interested in finding ways to unlock this baby, as i'm getting one as well to use on my provider.

have any one tried the PRO version of the SGS unlock from DaGentooBoy

https://market.android.com/details?id=com.DaGentooBoy.SGSUnlockPro

that one should work
[T-Mobile Samsung Galaxy S II SGH-T989] ssiddiqi1:
Pro does not work either. I wrote "None of the Unlock applications from Market work." I tried all of them. As a last resort I wanted to pull the nv_data.bin and edit it with a Hex editor, i.e. when I realized there was no nv_data.bin under /efs on this phone.

To answer your other comment actual development, unless actual problem is presented in development section, most people will ignore it. You are talking about a fine line here what people can post or not post in Development. As I read if only actual Development then, if I am you, I would either move or delete 90% posts in that section, as most of them under different Threads are chit chat, not actual development, not even development help to developers.

Or, unless you consider developers only the people you know as developers. Regardless, I will find a solution to SIM Unlock, and NO IT WONT APPEAR IN THIS THREAD, if I do find a solution. I do not consider it SGS2 SIM Unlock at present a "General" chit chat issue. That is why I said, I am out of here.

[T-Mobile Samsung Galaxy S II SGH-T989] ssiddiqi1:
Hi Tenxo,

My first post was directed at developers. Unfortunately, I hate to say that Moderator does not kow what he is doing. He had been bouncing my post from one thread to other. I wonder if he knows development? Again, I hate to say, I doubt he does. He suggested that I try SGS lock, but fail to realize that if not all, but most unlock apps in Market look for nv_data.bin, which does not exist on TMO SGS2. When I tried to explain him, he bounced again my post and merged it with his thread. So, if I do find a solution, I might PM you, but NO I will never post any of my contributions on XDA. I had in the past but after todays incidence, I would not. I do not like beatig my head against moderators who have no clue of development themselves.

My response may sound unfriendly to many, for which I apppolgize.

Regards
[T-Mobile Samsung Galaxy S II SGH-T989] fatnemesis:
I can add the following:

- There is no nv_data.bin file at all on this phone, so Samsung didn't just move it somewhere else.

- All files in /efs are very small (1-5 bytes) and contain text strings. Not a single binary file there.

Speak to a CSR - make stuff up - sound ignorant

I was looking for an unlocking mechanism today and was at a diner, so I just decided to ring T-Mo. Talked to a rep from menu -> "Technical Support". I told the rep that I travel a lot (which is true) and it is reflective on my account's "suspensions" (personally requested) whilst I'm in the UK and Europe. Within 10 minutes, she gave me a 7-digit number to enter into the link in an e-mail T-Mobile should send me within 24 hours from Saturday 4 PM PDT.

Is that what's supposed to happen?
