K300i unlock : can't do it!!!
 

Hi, I'm new here
I got a K300i that do not accept any SIM
I tryed direct unlock, unlock by codes, flash ARM, write raw FS, unlock RSA and nothing work

If someone here can help me I'll be very grateful!

replace certificate to brown 36 1st then attach again & unlock

just unlock one k3001 remove rsa first then convert certfiicate to brown then direct unlock thats it as what kcgckc2002 have said
