Docomo Galaxy Tab [SC01COMJK2] unlocked..sort of

I have been looking around the internet on how to unlock this tab (both English and Japanese websites) and I have came across this:
http://berorin.blog.shinobi.jp/Entry/1489/
According to this blogger, he unlocked his tablet by doing the following:
1. (本来使えないキャリアのSIMが刺さってる状態で)*7465625*638*#に電話
2. 使いたいSIMのMCC/MNCを入力(SBなら440/20)
3. ControlKeyに97286414
4. Unlock Saccessfull!的なメッセージが出たら再起動
5. 刺してあったSIMが認識される=アンロック完了
Translation
1. (With another carrier's sim card in the tablet) dial *7465625*638*#
2. Enter the sim card's MCC/MNC (For softbank it would be 440/20)
3. Enter 97286414 on the control key blank
4. A message like "Unlock Successful" would appear, and then reboot
5. The sim card's provider will be recognized (on your tablet) = unlock complete
SIMロック限定解除を解く場合。
To solve the limited sim unlock problem:
次に「#7465625*638*CODE#」をコール。
表示されるNetwork LockのEnter Network Lock Control Key欄に「97286414」を入力⇒OKをタップ。するとUnlock Successlyと表示される。
Next, dial #7465625*638*CODE#
The Network Lock screen with a Enter Network Control Key column should appear. Enter 97286414 then press/click ok. Once you do so, a message stating "Unlock success" should appear.
Now, I have the Overcome rom on my tab and tried this. It did not work. However, I am curious if someone with the original stock rom (Docomo) can successfully unlock this.
I do have network lock, network subset lock, SP lock, CP lock, and Data lock off but for some reason I still get the "Enter Network Control Key" message when I boot it up with another sim card.

Have you tried this one?

- If you use hexedit app, for clearer instruction do the procedure below :
1. Root the Tab, z4root.1.3.0.apk: http://forum.xda-dev...ad.php?t=833953
2. Install Super Manager as your root explorer. Enable root function in settings.
3. Backup /efs folder with Super Manager to your SDcard to be sure.
4. Open a copy of nv_data.bin in a hex editor. I installed HexEditor. Change 00181462 to 00 (note edit point is currently 01. It is the first two digits after seven "ff").
5. Open /efs with Super Manager set to Mount R/W and your modified nv_data.bin in the Root Explorer clipboard.
6. Rename or delete nv_data.bin and nv_data.bin.md5 and paste nv_data.bin (you have the originals in your /efs backup).
7. Power off the tab.
8. Insert new sim carrier.
9. Power on.

This method did work for the Docomo version of the galaxy tab. Many have attempted this and still had the network lock screen popping up.

I assume you mean did not work?
I also have a Docomo tab and am moving back to Australia after some time living in Japan and was hoping to unlock my tab. It's disappointing that the SC01C uses a different lock mechanism. I guess one of these little SIM boards that stick to your SIM to fool the device into thinking they are still on a different carrier might be an option. Selling it has become another option for me - I'm really annoyed that Samsung released this thing with all sorts of little arbitrary differences between different reasons creating lots of confusion about which roms can be run. Disappointing.
By the way I returned my SC01C back to stock, but I don't have a Docomo SIM so I have been using it WIFI only. I might see if I have another carrier SIM to try...
EDIT: I might not be much help as it appears my Docomo Tab is actually unlocked already. When I inserted an Australia Vodafone SIM in it accepted it but said 'No Service'. I would have thought it would have told me 'Invalid SIM' or words to that effect. Secondly, I tried the Softbank SIM from my HTC Desire in my Tab and it said 'Not registered on network', rather than warned me about the SIM. Is there any option I need to go to in order to test it further? I used my tab exclusively as a WIFI tab so far...

@zetsurin,
Have you tried changing the nv_data.bin on the /efs folder?
Rotohammer posted it works on all GSM Galaxy Tab.
Just be sure to back-up your original files, so you can revert it back.

Success!!
Ok, I decided to try the codes and I am roaming on Softbank with an Australian Vodafone SIM using my SC01C Docomo tab!
Firstly, to summarise everything the following Samsung codes are involved:
*#7465625# = Check the locks
*7465625*638*Code# = Enables Network lock
#7465625*638*Code# = Disables Network lock
The whole 'Code' business confused me. So basically you enter it like this:
Firstly, I entered *7465625*638*#. If I enter '505/03' (Vodafone Aus) and then 97286414 for the control key, I actually get a 'Lock successful' message, and in fact I saw some other Japanese blogs mention this. This is because that's a lock request, rather then unlock request. So I decided to enter the lock check (first code) and it confirmed I have a lock on.
Then I entered #7465625*638*#. It requests the control code only this time. So I then entered 97286414 and bingo I see the 'unlock successful' message and then the lock check confirmed my tab is unlocked.
Finally I selected Softbank for roaming with my SIM and it worked perfectly. I believe this is the correct way to unlock the SC01C we have as it doesn't have the same format nv_data (I've seen several sources say this actually).

thanks!!!
i was able to unlock it.
problem is, im not able to register to either docomo or softbank. i wonder what's wrong since i can do this on my galaxy s.

Thanks Everyone, unlock successful!

This really worked..... Thank you so much!!

works, but ony until restart
Hi!
This is the first method, that really works with my docomo galaxy tab. Thank you verry much, for the manual!
Unfortunately it only works until I restart the phone. After restart it asks for network lock key again, and I have to do the whole process from the begining.
Is there any way to make this unlock permanent?
(I also tried several other methods, like haxediting, etc,)

I have an ATT SGT with Overcome ROM, and just unlocked my TAB with an app I got on the Market called Galaxy Tab Unlock. Worked without a hitch. I had no unlock code or anything from ATT. I have used different SIM's and they all work. Also have data working with non ATT SIM's after putting in the APN's. The app, once installed, is called Galaxy S Unlock, but works with my TAB. Painless!

Yes, it worked until i reboot the tab.
no solution for this issue yet?

[Q] Unlocking Optimus Black

I have Optimus Black from Japan that unfortunately locked to Docomo.
It's gift from my boss
Is there any way to unlock the sim
so I can use with local provider (Indonesia)
Thanks in advance.

Found this,
1
Get the IMEI number for your phone. This is also known as the International Mobile Equipment Identification Number. You can do this in one of two ways. Remove your battery, and look for the 15- to 17-digit number underneath it, or type in *#06# and wait for it to appear on your screen. Once you've gotten it, write it down on a piece of paper.
2
Find a website that sells unlock codes for LG phones, like TheTravelInsider.com. GSMLiberty.net and GlobalUnlock.com (see Resources). As of 2010 these sites charge between $9.99-$24.99 for their unlock codes (prices as of 2010).
3
Go to the site that you have chosen and enter the IMEI number. Find the make and enter LG, then enter the model of your phone, the country that your phone is registered in along with the mobile service provider, and click "Submit." This will bring you to the next page, where you must enter your payment details and a valid e-mail address.
4
Get the unlock codes from your e-mail.
5
Turn your phone off, removing the battery and the SIM card.
6
Get a SIM card from a different network. If you don't have one, borrow one from a friend or purchase a prepaid card from any convenience store.
7
Replace your battery and turn the phone back on. When it comes on, it will ask you for a code. Simply enter the one that you got in your e-mail exactly as you see it. Do not add any additional spaces or characters. Enter "OK" and wait a few seconds. The phone will beep and flash and turn off.
8
Wait a few more seconds and it will turn back on automatically. If it doesn't push the "On" button. When it comes back look at the top of the screen. If the unlock was successful the new network name will show. If it doesn't work the first time, try the unlock code again.

that would be my last option actually
I would like to do unlock by myself first
so I came to XDA to search some tutorials but no result
thanks anyway

U cant unlock a simlock on your own.

(Note: In France, after 3 months, you have the right to get the unlock code free)
Just to know, that's not possible to unlock phone using Custom ROM, right ?
In this case, I suppose we have to go back to Stock ROM but what version !?
I had v11c first, I guess I had to flash this one. But will it work if I flash v20n ??

Of course different software/rom work, but different sim cards wont work. Simlock has nothing to do with roms ;-)

I'm in the same situation, trying to unlcok Optimus Black, and saw this on xda: http://forum.xda-developers.com/showthread.php?t=2137840
Haven't been able to make it work though. I'm having trouble with my PC communicating with the phone. adb, USB Mass storage all work. But the COM port option is not available in SmartFlash Tool.

Xperia T is Hard Locked

Hey everyone.
I am having a real problem with my Sony Xperia T. I have searched forums and google to find a solution and nothing. Also this website is probably best when it comes to sorting out android problems. My Sony Xperia T (I think) is now hard locked. O2 (UK) sent me an unlock code which did not work and now I get the following within the service info > sim lock:
[X] network 0
[] network subnet 0
[] Service Provider 0
[] Corporate 0
[] SIM 0
I think this status means its still locked and I cant use an unlock code anymore.
Also I can't unlock the bootloader because I get the following:
Rooting Status:
Bootloader unlock allowed = No
If anyone could help I'd appreciate it even if someone can point me in the right direction
Thanks again,
Regards David

Normally the phone gives you 10 attempts. Did you use all 10? Looks like you may be stuck.
Also, not surprised about the Bootloader unlock allowed = no. A lot of our phones (that came from a carrier) have this status and there is currently no way to make the bootloader unlockable.

It first came up as only 5 attempts and trusting the code I've used them all up.
Yeah I agree a lot of Sony Xperia's have the bootloader set to 'no' currently haven't a clue what to do

I wonder....if the 5 attempts were used by you on that code they provided (and it is certain that you were typing the code correctly), could the carrier be persuaded to replace or repair the unit for you?
Sent from my LT30p using XDA Premium 4 mobile app

That's the next step.
I'm hoping they replace the handset or at least fix it and I'm 100% i typed the right code in. I will keep this thread updated because I've seen a lot of Xperia's being hard locked and no solution!

Z3 compact network unlock

Hello
Please tell me which is the most reliable online network unlocking site for an ee uk z3compact ?
I've been to shops but they ask like £ 45/60 for unlocking and they do it the same by using internet sites ....
I also found some sites but not sure if they are trustworthy.
Thanks!

Do you mean
unlock=root or
unlock=boot loader or
unlock=phone from a specific carrier?

He said network unlocking.I think he means unlock phone from specific carrier.

The last one unlock=phone from a specific carrier and the carrier is EE uk !

Can you post a screen what are the values for your SIM LOCK?
in the phone dialer enter *#*#7378423#*#* (SERVICE)
Enter Service info > SIM Lock

Network is 5 so is not blocked , the unlock counter is not 0 !

I've been reading up a little on this, and found out that there not so many tools to force unlock the phone without an unlock code.
Also reports of using tools for HTC/Samsung (could not find any Sony related) not correctly (or sometimes correctly) resulted in a HARD bricked device.
So I suggest to get that unlock code, so you'll be on the safe side.

Yes I'm asking what is the best site to buy the unlock code ???
Which is the most used by the xda developers users ......?

I never used it, hence I always buying already unlocked phones.
My friend used this site to unlock his T-mobile GS4 and it worked.

Ok thanks , unfortunately I've used another site ... hope is ok , I will let you know.

Today I got the unlock code , all worked 100%.

[Q] Can't network unlock and can't access service menu

Hey all. Very annoying problem (one of many really) here with my xperia sp. I want to change network providers and got my unlock code no problem from my current carrier, no issue there. However when I put in the unlock code I'm told network unlock unsuccessful. I've attempted it twice as I don't want to risk making things worse. I've tried to check the service menu to see if the counter still has attempts but I can't access that either using *#*#7378423#*#*. The code disappears but nothing happens. I'm using paranoid nexus android version 4.4 and I've a locked bootloader if that makes any difference. I did buy the phone second hand so I realise the person before me could've used up all the attempts but it was only about a month old at the time and the person was on the same network as I am (I got the receipt when I bought it off them). Just wondering if anyone has any idea how I could possibly unlock the phone by whatever means or even get a look at my service menu??
My network is Meteor in Ireland if that makes any difference.

I think it's possible that you have to be on stock rom to unlock your device.
And service menu is not accessible in costum roms. Possible that it could be installed, I don't know.
Do the following steps:
1. Make a nandroid backup.
2. Go back to stock rom using the tool "Emma".
3. Do your unlock stuff.
4. Root and install recovery (get the same recovery as you use now!)
5. Go back to your current configuration by restoring your backup.
If you haven't used up all your attempts and your old carrier has given you the correct code, this will surely work!
If you have any further problems with unlocking, reply to this thread by quoting me! That way I'll get a notification. It's better to ask and wait before you've used up all your attempts
