Galaxy Tab 10.1 Sim Unlock?

[Blindi]

Hello and good day!

Is it now possible, in any way to rid the Galaxy Tab 10.1 GT-P7500 from its simlock?
I still have not found anything, but I will not give up the search and that's why I open a thread here to ask this question.
I've also tried it with the guidance of the old Galaxy Tab but as you can see without success!


Would appreciate answers and a solution!
Excuse my bad English, but Google translator had to grab me a little under the arms. :-D

yes should be possible.. first of all you need to root your tab (check google: root P7500)

after this it should be possible to modify the nvm to clear the locks (in this part we can help you via teamviewer)

[Blindi]

My GT-P7500 Tab is Rooted, which was / is no problem.

Can you explain the process of modifying NVM also step by step and I try it myself?
Or where there are online manuals?
Or special hardware is required?

But if you would have time and inclination for it, it would be great if you can help me! : D

okay.

you have to install adb on your pc (android debug bridge)
then start adb and SU on the phone

now do a "dd if=/efs/nv_data.bin of=/sdcard/nv_data.bin"
this will copy the nv_data.bin to the root of your local phone SD

close ADB with exit
and then type ADB Pull /sdcard/nv_data.bin

now attach your nv_data file to this thread or upload somewhere so we can pick it up.. then i check for you if i can decrypt the unlock code

Although I have ADB installed on my PC, but my Tab 10.1 is rooted. So I can get out to copy the file and upload it so!
Nevertheless, thanks for the GREAT "How To".
Also, I'm not at ADB sight!

howto
start command prompt in same dir as you put the nv_data.bin

adb push nv_data.bin /data/local/tmp/nv_data.unlocked
then adb shell
then SU
now
rm /efs/nv_data.bin
rm /efs/nv_data.bin.md5
dd if=/data/local/tmp/nv_data.unlocked of=/efs/nv_data.bin
chmod 755 /efs/nv_data.bin
chown radio.radio /efs/nv_data.bin || chown 1001.1001 /efs/nv_data.bin

now exit and reboot phone
it should now be unlocked

Ok, I'm going to try and hope it works out! I still say now again, thanks very much for your great help !
And if works I will visit you and go drinking with you. : D: D

[Blindi]

Hello! So I've done all your steps from the beginning to the end over and over again!
But unfortunately it does not work.
Did it even as you have written to me with a question mark and with | attempted every 20 attempts were unsuccessful, however, always produce the same result!

However, with've uploaded a screenshot. Maybe you can find the error!
Thank you again

The nv.log say that: "MD5 open fail. (No MD5 file) : /efs/nv_data.bin.md5
"backup NV restored"

[123unlock]

hmm seems it's not rebuilding the new md5
you have msnmessenger ? then send me a Private message so i can have a look

now working on offline md5 rebuild (since this is not standard md5)

123unlock has my Galaxy Tab 10.1 GT-P7500 successfully unlocked within 30 minutes, and freed from his simlock.
Was great to see how serious and persistently he worked on the problem and my PC as if by "magic" worked.
He helped me through Team Viewer and VERY successful.

Man, I once again thank you very much for your great help, and I hope you continue to successfully unlock many mobile phones and tabs.

:-D
