This worked perfectly UK O2 to Unlocked Network... I had a small problem with the step 2 - saying it's could not find the files in french, I resolved that by moving the 2nd repair nv_data folder out of the 1st repair nv_data folder

Thank you!!!!

This is safer:

If you plan on unlocking your phone, please backup your /efs folder and make sure you have at least 6 files visible in the backup. If you don't see 6 files, then STOP and don't continue unlocking!!!

The six files you should see:



Thank you very much for all this info - Could you hel please, I have used rootexplorer to search for the /esf folder and it is not there, neither are the nv_data.bin ect files. What to do in this case?

Hi, at first a big thanks

I got a samsung galaxy tab which was locked to T-Mobile.
I followed your instructions and when I finished and typed *#7465625# in,the network lock was off

Then I was putting in a Orange sim and I could use the internet,market etc but when I tried to write a message or make a call he told me not registered to network.
I tried in mobile network settings-network operators-select automaticially but no joy.
Tried then a T-mobile sim and i was havin then straight away a signal.
Did i forgot something whilst unlocking?

Thanks for answers

The automatic setting will be t-mobile. Choose manual and select your orange. Make sure orange apn settings are in already.

My carrier unlock code is not working
Hey guys, just wanted to ask you subject matter experts if you had any ideas on my my network carrier unlock code is not working on my tab.

When I first got it a few months ago, I rooted it, then used ODIN to flash various overcom roms. Also flashed various modems, kernals, recovery, etc.

The thing works just fine... just I want to use another carriers sim with my paid unlock code.

By changing the software in your tab, without knowing it, you changed the file for the unlock code. No big deal, just go to

It takes 10 minutes to run the app. Write down the code. Put in some other sim card. Boot the tab. Enter the code.

Works like a charm:

Romania - Vodafone, switched to DigiMobil

I got scared at a moment, after second reboot (when updating media and asking for a reboot) I pressed home then a android icon appeard with a orange exclamation mark in a triangle. Pressed home button again and it rebooted.

Congrats guys, keep up the good work.
