HELP!! LG G2 D802 Int. 4.2.2 Jelly Bean ... Trying to flash CM12.1

Hello XDA , i'm trying to flash CM12.1 on my G2 using TWRP v2.6.3.2 ... i've been flashing ROMs for 5 years never i encountered this kind of issue ....
1.
i tried to flash the install zip i got this :

Comparing TZ version TZ.BF.2.0-2.0.0086 to TZ.BF.2.0-2.0.078E
Comparing TZ version TZ.BF.2.0-2.0.0091 to TZ.BF.2.0-2.0.078E
assert failed: g2.verify_trustzone("TZ.BF.2.0-2.0.0086" , "TZ.BF.2.0-2.0.0091") == "1"
E:Error executing updater binary in zip '/sdcard/cm-12.1-20151009-NIGHTLY-d802.zip'
Error flashing zip '/sdcard/cm-12.1-20151009-NIGHTLY-d802.zip'
Updating partition details...

And a failed message from TWRP

2. Then i remembered that CM12.1 require LP bootstack so i downloaded lp bootstack loki for d802
and i got an error :
This package is for device: d802; this device is g2.
E:Error executing updater binary in zip '/sdcard/bootstack-d802-LP_30d-loki-signed.zip'
Error flashing zip '/sdcard/bootstack-d802-LP_30d-loki-signed.zip'

And a failed message from TWRP
