Thank You Your Code Is Good My Phone A347 Is Worked Very Good.

thanks for the code great work

I do it the following way:

1.) Insert different carrier sim to get wrong card on the screen.
2.) Enter on the keypad *7465625*638*00000000*00000000#
3.) Nothing happens, press the end button once.
4.) Press *2767*2878#
5.) Phone reboots.
6.) Now enter #7465625*638*00000000# and simlock is de-activated.

This is also working with A127 from Cingular. Post results.

Thanks Zukison14!

I haven't tested yet but this is a really nice trick for the A127 and I think it can work too with the E256.

Thanks a lot.

good work bro solution working 100%

thanks.
