[Q] I-9000T unlocking problems

Hi,
I have tried to unlock my new Galaxy S to a different provider. I have obtained the unlocking codes, however when I change chip of the new provider, switch on he phone and try to install the new codes. I do not get to that screen that you input the new codes. I get something like provider blocked or something.
There is other way to insert the unblocking codes ?????
thanks for your help

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.

- 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] I can't unlock my phone!

Hi guys. I have a problem a bit similar to the ones I read earlier but my problem is that I entered my PIN code and phone didn't recognize it. Now I should have an option to enter PUK code and everything would be fine, but I don't have that option. My screen says: "Take a look at the manual or contact with your service provider" (something like this, my phone language is Polish so I may translate something not correctly). I did take a look at the manual but there was nothing that could solve my problem so I'm asking you, members of xda community, is there any way to solve this problem without taking phone to my GSM provider?

If you are using custom rom try full wipe maybe it would hep
Sent from my X8 using XDA App

It didn't work, but it turn my phone language into english so I can write what it says:
"SIM card is PUK-locked."
"Please see the User Guide or contact Customer Care."

If you inputted a incorrect PIN for too many times the SIM card will lock up and require the PUK to reset the PIN failure counter - that much the phone is actually doing right.
If you don't have a possibility to enter the PUK then all you can do is to see a service point of your mobile operator to have the SIM card resetted.
There's pretty much nothing you can do as that's a security function of the GSM card and not the phone or the OS.
EDIT: Any chance entering **05*<PUK Code>*# or **05*<PUK Code>*<New PIN>*<New PIN confirm># works? (in case you can get to the dialer)

I can get to the dialer, but I didn't know that I can enter PUK there, I'll give it a try and write either it worked or not.

The second method worked! Thanks! When I use this first method it says that is either connection problem or MMI code is invalid.

Hi there, i know that there is LG hidden menu and i know it works, i wonder if there are any other codes ?
Another question: is there way to unlock phone incase i got stuck with one of the lock screens? Like pin code screen.
For now im not using any kind of lock hcoz i dont know how to pass this without a factory reset.

You can reset the lock using your email id and password. The option shows up when you enter wrong code 5 times.

2945#*970# to SIM lock/unlock menu. but i dont know how to use it

It looks good but i need to have data service, in my case i dont hava data. In this case can i still use the wi-fi ?
I try the code 2945#*970#, i got in sim unlock process. Anyone knows what to do there ?
Here is a SS of that menu
posted from another universe

have the dialer codes changed?

I am trying to use the dialer code *#*#DATA#*#* so that i can change the lte band priority. This has worked for the nexus 5 (and note 4 with similar code) but the dialer code is not bringing up the data menu. Anyone know if the code has changed or if it is locked out for the time being.

*#*#4636#*#*

That one works, but the one in which sprint users (and possibly others) use to prioritize lte bands *#*#data#*#* does not work. Sprint uses 3 bands for lte (25, 26, and 41). Band 41 is spark (high speed) and only gets priority if the others (slower speed) are not available. This menu also allows for many other adjustments to the data connection through the carrier. It has worked on all of my android devices [samsung uses ##data#] in the past but seems disabled on this device. Other dialer codes do appear to work but have no purpose for me at this time.

I've been wondering that myself. I got my Nexus 6 today and I can't access the menu. I wonder if there is another way to access it. I will have to do some digging into the fimware.

+1 for this I've been searching for this. I don't feel I'm getting the best speeds ever

I was able to get in to data settings using *#*#3282#*#* (t-mobile nexus 6).

Seems that 5.1 has returned the feature for accessing the dialer code *#*#DATA#*#*

If I want to edit anything in that screen it asks for a "passcode".
I have no idea what that passcode would be. I tried all of the codes I have (SIM pin, phone pin) but none seems to be working.
Any idea?

Most likely the MSL code. [Master Subsidy Lock code]
I haven't tried to obtain mine yet to try it, but this has been the code used in all my previous devices.

Yes, you will need your MSL from Sprint.

The passcode turned out to be much simpler than expected:

See, I've tried that several times, I've watched logcat as I tried pulling the MSL via hex, I tried a getprop to look at all the properties, nothing shows for SPC or MSL. I've also talked to sprint, and even though I bought the phone outright, they're stingy and still don't want to give up the blessed code.

Sprint codes
I know this is an old thread but it showed up pretty high on a Google search I did so I wanted to explain why some people can connect with *#*#DATA#*#* and why some cannot. Assuming you are on Project Fi.
It's simple. You have to be on Sprint's network for sprint codes to work. If you are on Tmobile or other network then the codes are meaningless. The reverse would be true of Tmobile specific codes too - just enter the correct carrier code in prior to your carrier specific "special" codes. It doesn't matter if you are simultaneously connected to Wi-Fi however.
