Hello people,
Here is the procedure on how to use the following patch.

patch link

Firstly, paste the files their respective folders.
Then the following changes have to be done in init.mt6753.rc so as this patch would work.

1) init.trustonic.rc file in ramdisk
2) import init.trustonic.rc at the start of init.mt6753.rc
#add for fingerprint
chown system system /sys/bus/platform/devices/fpc_interrupt/irq
chown system system /sys/bus/platform/devices/fpc_interrupt/clk_enable
chown system system /sys/bus/platform/devices/fpc_interrupt/do_wakeup
chown system system /sys/bus/platform/devices/fpc_interrupt/wakeup_enable

#add for fingerprint
service fingerprintd /system/bin/fingerprintd
class late_start
class main
user system

service fastmmi /system/bin/fctd
socket fctd stream 666 root root
service mtk_fctd /system/bin/

These, i found in init.rc and factory_init.rc of ramdisk, then flash the new bootimage.

wipe cache and data.

Now the fingerprint will work

Thanks to :
Dhruv Madaan for giving me the device
Shripal Jain for supporting me.

Hit thanks if you like my work.

Nice work bro....Now we have got the most painful bug fix....I understood your guide easily....But here are many people who could not understand your guide as they just download the rom in ready to flash form and flash it....So u should edit your post and write that the people who didn't understand the guide should not do anything until and unless any rom with fp comes....
