For people like me who didn't know one thing about adb
[Galaxy Tab General] sbl03:
Can anyone confirm this works on Gingerbread 2.3.3?

Thanks!!!

I did exactly the HEX edit, but it does not work? I type *#7465625# into phone and it still says Network Lock.
[Galaxy Tab General] koovoodoo:
Awesome work. Thanks again. I was going to call in and ask for the code, but figure it'll be more convenient to do it myself.
[Galaxy Tab General] TheATHEiST:
People, There is no need to mess about with any hex editing or any other sort of editing to your Tab, Just simply download the "Galaxy S Unlock" app from market and get your code, swap Sim card then wait till phone reboots and enter code. Worked great on UK T-Mobile Tab.
[Galaxy Tab General] rangercaptain:
And dont forget to donate to chainfire. His app deserves that!
[Galaxy Tab General] porto35:
Perfectly works. Thanks chainfire
[Galaxy Tab General] lattensepp:
Work the adb Method also without a SIM Card or I need one?

No unlock yet for me...

I updated my AT&T Tab to the Euro firmware before trying chainfire's app and in returns all zeros for the code...

Has anyone been down this road our should I go straight to the hex editor? I also tried the SGS Unlock Tool without success.
[Galaxy Tab General] toyfreak:
Success?

I just ran Galaxy_S Unlock by Helroz and *#7465625# shows lock off for all four items reported. Now time to try a non-AT&T SIM card.
[Galaxy Tab General] rangercaptain:
Getting there!
[Galaxy Tab General] toyfreak:
Finally got to try a T-Mobile SIM last night and my SGT recognized it so that unlock tool I used worked. It was pretty slick too, made a copy the files it altered for restoration purposes if necessary.
[Galaxy Tab General] guillaumeux:
It worked with french Orange Galxy Tab, nice job !

Thanks !
[Galaxy Tab General] michaelgening:
I have the #, but it still said "rm failed ...", what should I do? Please help! Many thanks!
[Galaxy Tab General] michaelgening:
Have a question, does this method work on any baseband? I got a used one, the previous user flashed the rom to overcome, but didn't touch the baseband, it's a tmobile tab, and I failed to unlock it, so could you or anybody else help me with that? Thanks a lot!
[Galaxy Tab General] Androw:
If you want a simple one click unlock, you can use [root] Unlock My Android on the market
[Galaxy Tab General] cecco_78:
... il mio Tab ha tutto in OFF.... ma funziona con sim estere e non con quelle italia!!!

perche? che cosa devo fare??...

… my Tab has all in OFF…. but it works with foreign brokerage houses and not with that Italy!

why? what I must make? … please help me!
[Galaxy Tab General] rangercaptain:
The baseband is only the modem, so this has nothing to do with that.

You failed to unlock the tab by what method?

You only unlock a phone/tab if you are going to use it with another carrier's sim card. That would be a mistake since t-mobile tabs only get 3g data on t-mobile network.
[Galaxy Tab General] cnewsgrp:
I confirm this works for TMO SGT. Thanks:D Put in an AT&T SIM and was able to browse data. Calls did not work, I will figure that out.

Note: I first tried the method in OP and it erased by S/N. Fortunately I had made a backup.
[Galaxy Tab General] sentaroking:
When I paste the command in the second box, I got permission denied. Can someone please help me what i should do so that I can unlock my SGT?

Thank you

Edit: Finally, I've been able to figure it out.

Thank you so much.
[Galaxy Tab General] flybd5:
Just tried the shell instructions with a T-Mobile 849 tab that I modded to the Euro ROM and 2.3.3. *#7465625# confirms the tab is now unlocked. Outstanding! :)
[Galaxy Tab General] motoyola:
works for me :)
[Galaxy Tab General] giggaice:
Can some please give me a clue? I'm thinking of getting an Unlocked samsung Gt - p1000 32gb version from the USA, since in Russia they aren't avaliable. pla tell me will the 3g, gps, etc work in russia?
[Galaxy Tab General] rangercaptain:
The gps will work everywhere. To advise you on the 3g you will have to tell us your carrier and region. Don't buy your tab until you know this.
[Galaxy Tab General] giggaice:
my carriers: 1) МТС (MTS) russia,

2) Мегафон (Megafone) Russia. Please help:confused::confused:
[Galaxy Tab General] rangercaptain:
MTS and Megafon use the 900/1800 bands for voice and the 2100 band for 3g data. I would flash the JPE modem, as this was recently reported to me to work well on those bands.

http://www.prepaidgsm.net/en/russia.html

Are you buying a carrier-branded tab? What carrier?
[Galaxy Tab General] giggaice:
im buying an unlocked phone. Thanks a million 4 ur advise;)
[Galaxy Tab General] mhj123:
I was able to use rotohammer's script to unlock my Bell Canada Galaxy tab and all seems to be working fine. It no longer asks for unlock codes when I put another SIM card in. I hope to use this when I go to the UK next week.

For some reason, after the rooting (with superoneclick) and running the script, Kies does not want to offer me a firmware upgrade anymore. Does anyone know of a connection? I think I might have been about to upgrade to 2.3...
[Galaxy Tab General] rangercaptain:
You don't need kies to upgrade. Get any rom from www.samfirmware.com
[Galaxy Tab General] mhj123:
Thanks. Is there a good step by step for doing this? I am an android newbie, though I was able to root and unlock my tab using the instructions on the first page! :)
[Galaxy Tab General] rangercaptain:
The best place to learn the basics, and a safe way to learn, is to go to the development section and read the first post for the Overcome rom. You can download agood tutorial, and get all the files you need.

After you successfully do that, then try other roms, because you will know how to do that.

Good luck. Its easy to do, just read carefully.
[Galaxy Tab General] iarapilot:
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!
[Galaxy Tab General] MagicMan3:
I can confirm this works slick on rooted stock rom on rogers galaxy tab. Put my bell card from phone in and works great.
[Galaxy Tab General] monomo:
I got an galaxy tab sp100 sprint

My tab has a number under the info, and it has an meid, so Can I put this on like say metropcs?
[Galaxy Tab General] captirwin:
I have a 7" tab, model GT-P1000 with gingerbread 2.3.3 installed. Works fine.

Will this app work for me?

Thanks.
[Galaxy Tab General] iarapilot:
I cant promise it will, but it worked fine for me. I have a 7" Tab on ATT with an Overcome ROM.
[Galaxy Tab General] entranceon:
It Woks

I used the same APP GALAXY S UNLOCK on my T mobile (european whatever 2.3.3) and woks for me... so f happy :)
[Galaxy Tab General] lettcco:
quick question: when you restock, will you stay unlock or do you have to do it again?
[Galaxy Tab General] iarapilot:
I just did a clean install of Overcome ROM, and it stayed unlocked.
[Galaxy Tab General] Ryplok:
Tab relocks after going into roaming. Why?

I have been facing a very odd issue and I decided to share it with you - it doesnt make much sense, but as the Spanish say, "yo no creo in brujas, pero que las hay, las hay" - i.e. the ghost in the machine.

I have an ATT Galaxy Tab which I changed to EU firmware, enabled phone calls using the Bell modem, etc (as described elsewhere in the forum). I unlocked it using Rotohammer's wonderful tool (adb shell, etc). Worked like clockwork.

One day, while travelling, the thing just relocked and started asking for a network unlock PIN. I tried everything but the only solution was to run Rotohammer's script again. My Tab was unlocked...until I travelled again. It relocked - and I realized that this happened as soon as I landed and the device went into roaming. In fact, this was the same situation that happened the first time ( I just hadnt linked roaming and relocking).

Now, my guess is that my modem file is somehow corrupted, but this is just a wild guess.

I now decided to install the latest firmware, including Rotohammer's JDC firmware, and also reinstalled the modem firmware, but I would like to know if anyone had any thoughts on this. I fail to see how going into roaming may cause the Tab to relock.

A big thank you to Rotohammer and Ayman07 for their hard work.
[Galaxy Tab General] JFDBY:
Thanks a million

Dude,

This info was great ,I had the same numbers and i did change the 01 to 00 and yes my t-mobile tab is unlock too checked with the *#7465625#

Build Froyo.xxjma

baseband p1000xxjha

Thanks again !

[Galaxy Tab General] onikage:
Hello! is there a way to get the NCK for carrier locked tabs like the SGS models? i've read dagentooboy's post on SGS models and it works fine on SGS models but I was wondering if that code generator would work on a galaxy tab.

dagentooboy's post --> http://xdaforums.com/showthread.php?t=761045

this australian guy successfully unlocked his carrier locked tab using the NCK posted on this link --> http://xdaforums.com/showthread.php?t=1056788&highlight=docomo#

if there is any available code generator for galaxy tab..please share. thanks a million.

no offense to rotohammer though. ima try this process too if i can't get an nck code generator.

cheers!

Unlocked tab randomly drops into emergency calls only

I have a tmobile tab 7 inch using stock EU gingerbread with dialpad, I am using a atat sim card. I first unlocked with galaxy s unlock and phone sometimes worked but most of the day it showed emergency calls only then I unlocked with sgs unlock pro from market and same issue....It kind of choices when it wants to show atat and then I can make a 30 minutes call and the moment I get off the call it goes back into emergency call only mode...

Optus version unlock

hi, need an advice. About to unlock my Optus version device, but the /efs folder appeared to be empty :confused: Rooted. What can be done?

thanks

hi, i have the same device (optus), when trying to unlock it, the folder /efs appears to be empty. i have rooted. what could be a decision?

Sorry for double posting.

[Galaxy Tab General] luminouche:
Hi !

Need a little help (if possible) ! :D

I tried to unlock a French Galaxy Tab 8.9" (P7300) locked on Orange

In order, i did :

Backup of Efs folder

I've edited 0x181469 from 01 to 00 (on Windows computer)

Deteled nv_data.bin and nv_data.bin.md5 in Efs folder

Put back new/modded nv_data.bin in Efs folder

Reboot

With non-Orange network sim, Tab still asks for a network unlock code

I took back "new" nv_data.bin to computer to read it, and byte 0x181469 have been changed back to 01

nv_data.bin.md5 created in folder (or taken from .nv_data.bak.md5)

If you read joined nv.log, you can see that my modded nv_data.bin has been replaced by backed one :

Thu Oct 13 00:08:42 2011: MD5 open fail. (No MD5 file) : /efs/nv_data.bin.md5

Thu Oct 13 00:08:42 2011: backup NV restored.

Thu Oct 13 00:22:10 2011: MD5 open fail. (No MD5 file) : /efs/nv_data.bin.md5

Thu Oct 13 00:22:10 2011: backup NV restored.

Thu Oct 13 00:27:20 2011: MD5 open fail. (No MD5 file) : /efs/nv_data.bin.md5

Thu Oct 13 00:27:20 2011: backup NV restored.

I tried at least 3 times :D

So, everytime i reboot without md5 file, my Tab restored bak file (instead of regenerating new one), unlock is then impossible

Galaxy Tab 7in - P1000 Unlocked

Thanking rotohammer (http://xdaforums.com/showthread.php?t=843323).

Australian carrier was NOT what you would call "helpful" with request to unlock a P1000 for use while traveling in international destinations.

Model: GT-P1000

Firmware: 2.2

Baseband ver.: P1000XXJID

Kernel ver.: 2.6.32.9

Used latest SuperOneClick, RootExplorer(File Manager) and HexEditor for Android to root, unlock the device. Easy as pie for an Android first-timer.

Great site and contributors, Many Thanks.

[Galaxy Tab General] alalor:
One way worked

Hello, thank you very much for the info. I changed the first address, the second was already 00 and rebooted, turned off airplane mode and a minute later I got a message from Movistar Argentina (the sim card is from them) and I am in the USA. So that worked fine. Can't wait to go there to test it.

What did not work was my first attempt. I downloaded JAVA and the Android SDK, installed everything, opened the shell and put your code, I kept getting access denied, and messages like that. So when that didn't work, I decided to figure out how to edit hex, which was much easier than what it sounds!

Thanks again!

[Galaxy Tab General] mariol66:
I have a question if anyone can help. I sold a tab to a guy on ebay with it able to call and text and get data from a regular cell phone SIM card on ATT. He got it and went to ATT to buy a month to month SIM card with just data on it and the tab wouldn't read it. Its running Overcome v2 which is old. If I instructed him to flash the stock ATT modem would that fix the problem of not reading a month to month data SIM, or would I need to go back to stock firmware?
[Galaxy Tab General] FL00DY:
Hi. I'm trying to unlock a T-mobile SGT that woman at work purchased in the US, she's now home in Australia and wants it unlock to use with an Aussie telco. Having a SGS I was well versed in what would be needed.

Rooting it wasnt a problem, but when I tried using the script updated in the first post, it wasnt working. Eventually I renamed nv_data.bin to nv_dataOLD.bin, this then went through and rebooted the phone.

So I've put a Vodafone SIM and it's just sits saying (Searching). Should I need to change to a different modem, or did the unlock not work? If so, for Australia, which one? I'd like to update it to the latest firmware ...

Thanks for any help.

EDIT: Just read a post, if you see $$ in adb then root isnt working properly. Will try shell root from superoneclick.

thanks a lot for this tutorial

this is what i got after using your method (also after using SIM unlockers on the market for galaxy S and galaxy SII .. Now the tab can recognize the sim card, and i can text and receive texts but no calls :(

i started this thread on unlocking my rooted galaxy tab, p1000, android 2.2
[Galaxy Tab General] rectangle:

is this method permanent?

if i change roms or something, do it need to do this procedure again?

If you flash a rooted rom you keep root. Some developers forget to root their rom.
[Galaxy Tab General] sakurasyaoran:
this steps truly works

i managed to fix my unlocking issue with this method. before i try this i already got unlock code that i bought online but it doesnt work. then i try this method and enter unlock code now my tab is unlocked. this solve my issue.. thanks again..
[Galaxy Tab General] scanferr:
Hope someone call help me with this issue.

I tried to unlock my Tab using this method but there is a problem. I can't find that HEX value on my nv_data.bin. None of those 2 values are present on my file.

I tried this with stock ROM and using the CyanogenMod 9 and can't still find it.

The second method I don't know how to do.

Suggestions, people?
[Galaxy Tab General] jr97ai:
Hi,

I used the Galaxy Tab unlock tool developed by a member of the XDA forums. It was in the market place and cost a few dollars but after my tab relocked itself about 6 months after entering an unlock code it was what I used. It does all the work for you and you can backup and restore to critical files automatically during the process.

I am not sure hoe editing it manually works but in my case I have to restore when I want to check for firmware upgrades but it is very easy.
[Galaxy Tab General] supersincero:
Strange

I unlock SIM using Hex Editor e works goods.

BUT, after 2 days the Tab RELOCKED. I extract again the "nv_data.bin" and shows locked again.

Anyone knows why he RELOCK??. How its possible??

Sorry my bad english

EDIT: I discovery something, IF the tablet stay few hours power off, he change the "nv_data.bin" to default, in other words, he RELOCKED the SIM.

How can I fix that??

[Galaxy Tab General] CyaN1de:
Trying this on my P7500R

Will let you know if it works here.

EDIT: Nope, on reboot with SIM card in it asks for unlock code.

Has anyone succesfully unlocked their Rogers Galaxy Tab without paying someone in order to do so?

I wonder if the following has anything to do with it?

Does this mean the tab is making a backup before the file is edited and then being overwritten with the backed up file?
[Galaxy Tab General] sos_sifou:
yes, it did generate a backup, and this backup should be somewhere in your sd card or efs folder, and then i think this unlock method is not for your device, you have different galaxy tab! yours is the newer one, you should look elsewhere for the unlock code.

If I helped you, please press the thanks button
[Galaxy Tab General] CyaN1de:
Thanks. I have been looking for days now. I was hoping this would be the solution.

Roaming not recognized

I tried your method and it worked, however, when I put an AT&T SIM in my Rogers Tab while in Canada the Tab doesn't recognize it's roaming and proceeded to use mobile data as if it was in the States. I thought maybe the Tab was converted into an AT&T tab so I tried my Rogers SIM and it still doesn't think it's roaming. Is there a way to have the phone recognize it's roaming?
