now working GT-P7500
Now working on a Galaxy Tab 10.1 from Rogers canada, GT-P7500!
I've buy the app Galaxy Tab Unlock from dagentooboy.
Here's a small how to. Skipping the rooting...
Open the Galaxy Tab Unlock, Problems? MD5 Generation (currently Off) Enable.
I had to use adbWireless because I forgot my usb cable to change the permission of the nv_data.bin
Remember to activate USB debugging in device settings
adb connect 192.168.x.x
adb shell
chmod 700 /efs/nv_data.bin
exit
adb disconnect
Reboot (maybe not necessary)
Start the app Galaxy Tab Unlock, Unlock Tab, Unlock, Restart, Quit, Press power button and Reboot. IMEI and Serial = ok. Had to wait 3 minutes before my provider been detected. now working with a Telus or Bell SIM card.

Just wanted to say thanks for the app. I used an unlock from mobilecanada and it was unlocked since December. All of a sudden yesterday my device sim locked again... Not sure why or if that should happen. Anyways... tried the manual unlocks and could not do so took a chance on your app. It worked perfect and I am back using my Bell sim in my Rogers tab.
Thank you!
Thank you!
IMEI 0049 on Galaxy Tab 7.0 Plus P6200
Ok, I've managed to unlock two P6200 tabs, but I couldn't solve the 0049 IMEI problem. Luckily, the /efs data can be restored at any time, including the right IMEI, but the SIM lock is restored as well...
Did anyone solve the IMEI issue on the P6200 tab?
Maybe an updater script attached to an update.zip archive and executed under the recovery program could do the job? (the nv_data.bin file can be "built" from pieces in order to include the simlock byte change from 01 to 00).
thanks

I don't have a 7" tab but if there is an nv_data.bin that is a good start. Can you email me the entire folder (before and after the unlock) zipped up? Use the paypal email in my sig.... I will see what I can come up with.
For some reason cat /efs/.nv_state >> /sdcard/.nv_state does not copy .nv_state to sdcard. So all you have to do is to put/copy it manually to sdcard from backup and to follow the process from the first post without cat /efs/.nv_state >> /sdcard/.nv_state line.
Successfully unlocked my gt-p6200! Thanks to all smart people out there
EDIT: It actually copies the files but there is some problem with MTP and .files(hidden) . So I copied both files to pc, changed the nv_data.bin and copied them back to sdcard.

Before you do anything copy the efs_backup folder over to your computer just in case something happens to your backup.
Restore from backup and reboot.... make sure that everything is ok (locked but IMEI matches)
Now try the cleanup function (click the Problems? button) then unlock... reboot... if that doesn't work restore, reboot, cleanup, change the md5 generation, and unlock again.
Thanks for the unlocking instructions. After a quick visit to ICS my Tab somehow simlocked itself and there was no 3G for me anymore. But thanks to this thread I managed to get rid of the lock.
BTW, I had to change .nv_state from 1 to 0, otherwise the unlock wouldn't work or my IMEI dissappeared.

Good to hear. I don't know why the Tab has been so different from all the other SGS models.
Hi dagentooboy,
I just bought the app for my P6200 and unlock was successful.
I did a complete wipe and now the TAB wont start and keeps on looping in Samsung Startup logo.
Also did re-flashed via Odin and still have the same problem.
I still have a backup of efs folder in my pc incase needed.

Never Mind, Just did a Wipe and clear cache after flash and everything is fine.

I was going to say... the worst thing that messing with /efs/ has done is change the IMEI and SN. (yes that is bad) But no boot loops.
I must be stupid?!?!?!? I just bought the SGS unlocked Pro and it says that it has
unlocked my Tab 10.1 but when I insert the SIM, I get the window to put in the unlock
code. Where is this "Problems?" option that people are talking about?
Thanks

22So I managed to unlock my T-Mobile Tab 10.1 over the weekend and I discovered that it works on ATT at 3.5G speeds.
My Tab has several files in the /efs/ folder that weren't there in my previous Samsung phones.
Unlock App for anyone who doesn't feel comfortable with a hex editor
BTW... I cannot be held responsible for anything that happens to your phone.... EVER!
Before you start... if you don't have root you WILL need it.
ALSO MAKE SURE YOU HAVE A BACKUP OF THE /efs/ FOLDER
Step 1. - Retrieve nv_data.bin file
use "adb shell" or a terminal emulator to get a terminal prompt and run the following commands
Code:su cat /efs/nv_data.bin >> /sdcard/nv_data.bin cat /efs/.nv_state >> /sdcard/.nv_state busybox cp -r /efs /sdcard/
Step 2. - Edit nv_data.bin file
mount the internal SD Card on your computer
make a backup copy of the nv_data.bin file on your computer
using your favorite HEX editor open the nv_data.bin on the sdcard
jump to address 0x181468
you should see a string like this
ff 01 00 00 00 00
there are 5 different types of locks in 5 different bytes
the FF byte should be left alone
the first byte after the FF is the network lock
the next byte is the network subset lock
the next byte is the sp lock
the next byte is the cp lock
the last byte appears to be a data lock.
the 46 46 should be left alone
Change any 0x01 to 0x00 (or 0x00 to 0x01 to lock for warranty)
It should read ff 00 00 00 00 00 46 46 for unlocked
save and close file
unmount SD Card
Step 3. - Replace nv_data.bin file
I want to say it again so no one misses it MAKE SURE YOU HAVE A BACKUP OF YOUR /efs/ FOLDER BEFORE YOU CONTINUE!!!!!
use "adb shell" or a terminal emulator to get a terminal prompt and run the following commands
your tab is now unlocked... enjoyCode:su rm /efs/nv_* rm /efs/.nv_* cat /sdcard/nv_data.bin >> /efs/nv_data.bin cat /sdcard/.nv_state >> /efs/.nv_state chmod 755 /efs/nv_data.bin chown radio.radio /efs/nv_data.bin || chown 1001.1001 /efs/nv_data.bin chmod 755 /efs/.nv_state chown radio.radio /efs/.nv_state || chown 1001.1001 /efs/.nv_state reboot
If you have any trouble with md5 and IMEI stuff change .nv_state from 0x30 to 0x31 (or ascii 0 to 1)
Give a big thanks to all the people that helped with the original unlock method (in the i9000 thread)
If it works please feel free to donate via Paypal1
After you have a backup you can change that first 01 to a 00
FF 00 00 00 00 00 BC 9D D4
and you should be set... I had to delete all those other files in the folder. Could you tell me what files you have in /efs/?
su
busybox ls -la /efs/1
I have always believed in providing the solution to everyone... I don't want anyone to think I am only in this for the money. When I was looking for the i9000 unlock someone was charging $35 and there was no way I was going to pay that so I started on this path of providing the information for free.
Thanks to the economy I lost my job and had lots of time to code but no money for devices.... enter the PRO app. I get a lot of people that buy codes and then they don't work and they end up using my app for half the price (half the time the samsung unlock doesn't work even with the code).1What I did is just follow the instructions in the Overcome rom except the "re-stocking" part. Mine is running Overcome with no problems so far.1i´ve followed all steps. its pretty the same like the other devices like the gt p-1000. full success.
