Default [Q] Problem with custom ROM

Hi guys, sorry for my english, but I need a help. I have an Amoi A860W (MT6589), and I've trying to make custom rom from the original firmware. I've using dsixda's kitchen, and when I trying to flash custom zip it dont format /system! I must do it manually by "Mounts and storage - format system". I've look into updater-script, but its correct. Another problem is when phone turns on, ROM boots good, but phone dont see any sim cards! "Sim Toolkit" says that "app isnt installed", and in Settings menu "Manage SIM-cards" isnt active.
What have I done wrong? :c
