Разблокировать Samsung D900
First of all the D900 cannot be unlock simply by placing the Simcard of another network as was the normal procedure with other Samsung.
To unlock the D900 here are the steps you must follow:
1) First remove the battery from the phone.
2) Insert the sim of another carrier into the cell phone halfway.
3) Gently place battery back in the phone by cautiously lifting the simcard trying not to break it.
I hope you have followed these steps as I said!!!!!
4) Power on the phone after the above and
Input *2767*3855# and phone will reboot and will be temporarily unlocked
NB. Before the phone reboot fully after you have entered the code insert the sim completely which was mentioned in step 2.
5) When the phone reboot
Input *7465625*638*00000000*00000000#
6) Input #7465625*638*00000000#
Congrats you've got a Network free D900
