Entered code *#6810# and engineerine menu gone!!!!

[nashvilles]

I have Chinese 8600 with MTK 6226 cpu, i used to enter engineering menu with *#3646633# successfully but after entering *#6810# it just displayed "Done" message on the screen and after that engineering menu is disabled i cant enter it with any of the china mobile codes given on many web sites. There should be a code reversing the *#6810# command but i couldn't find it anywhere please help meeeeeeeeeeeeeeeeeeeeeee.

Please i don't wanna hurt anyone so DO NOT ENTER THIS CODE FOR TESTING IT REALLY DISABLES ENGINEERING MENU!!!!!
