I want to make a PAC file Firmware for Micromax Q402 Plus but eisting fdl binary are some kind of signed type. Previously I removed  this sign flag from my boot-sign img and recovery-sign image to unsign it and i did same for all existing sign file inside my Rom.(X3NON helped me with this)
BUT I failed to find this secure flags(secureboot ,VLR) from my fdl1-sign in HEX EDITORE and 
when i trying to flash with this files ,the flashing process keep going and going to flash fdl2.bin not stoping.
I dont have enough knowledge about assembly language and offsets.

Any one Helpme With this.

fdl2 seems to contain an spd signature, fdl1 doesn't (at least to the little i'm aware of)
try this, rename fdl2.bin to system-sign.img
use your signed boot.img and this fdl2 (system-sign.img)

unsign system using our tool @ https://www.hovatek.com/forum/thread-26890.html
the output file will be unsigned, you can rename the output file back to fdl2.bin

can't say for sure if your device will allow flashing using unsigned fdl files, you can test and lets know
