2.in system config select the AP and BP file;
Mrt aleady give the AP file for all the MTK phones; that put in the MTK_FILES Folder have
if cpu is MTK 6755 MTK 6797 MTK 6757 <after X20> not need BP file;just tick the load Modem DB form DUT
if old cpu,like MTK 6735....you need read bp file form mobile
untick the load Modem DB form DUT
in the SN Write software select the MD1_DB file,the max size one is bp file
how to read: run mrt software.imei tools,MTK imei,has read baseband ap bp<By USB debug>
with this,mobile need power on and enable usb debug,and connect computer,after auto backup the mobile ap bp imei file
