I will write a full how to now, so please read and follow it:
First save the dead phone`s keys as vkp (loader) and x65 flasher (ini) with papuautils and into a txt document manually !!
Then connect second one, and read the fullflash;
After, copy vkp loader into v-klay`s loaders directory, run v-klay, hope u will guess which model and method to choose !
Go to flasher page of v-klay, Open flash, check the fullflashing adresses and press write memory !
After successful flashing, open up papuautils, enter all original keys u saved in a txt document manually, go to flash page, tick only "Recalc keys in flash" (it will tick two options automatically) and Do Job !
After, Power up the phone !
If anything, u can use same method with x65 flasher instead of v-klay as well !
