Thanks!

Please do not download the patch... select i747m from the model and hit unlock... if you take more than 2 minutes you require more practise.

Thanks guys for reply. I was trying to figure out how easy to unlock GS3 with NSPro.
And looks it is pretty easy. I already ordered new box for me yesterday. I sold mine 2 years ago and going back again to NSPro - best tool for samsungs.
Thank to all!!!

Check the phone model on the label, under the phone battery.
Select the correct model (I747m, T999) on NsPro
Click UNLOCK
Fallow the Nspro instructions.
Phone will be unlocked in just few seconds.

No patch needed.

PS.
To fix a T999 or I747 damaged by flashing with i9300 patch, flash the phone with the original firmware from NsPro support area.
and... next time, CHECK THE PHONE MODEL!!!

Hello, but the download limit is 500mb per day and the flash file is almost 700mb and it is not resume download. How do I download the I747M flash file?.

Elco · 08-08-2012, 21:33

even if the download limit is 500 mb, it will let you to download the complete file.

I was able to unlock one tmobile s3 t999 but i want to unlock some other ones that i have and none of them work for some reason

tigran80 · 08-19-2012, 14:54

where can I buy the working cable for GS3 from?
I was surprised because my new NSPro came without s7070 cable at all. I ordered 2 different s7070 cables. None of them working with gs3.
I know, probably I have to solder the resistor. But I have no tools with me.
Share the link please.

READ this forum thread and you will find the solution.

I think you did the same mistake like @supermatrix

Check the phone model on the label, under the phone battery.
Are you sure that phone is i9300?
