[Resolved] how to install CM 12.1 on LG G2 - g2 verify trustzone Error workaround

so I got my LG G2 and think it'll be classic gone through cyanogenmod wiki - but it was missin one thing - you need to have bumped bootloader unless you won't be able to install nothing higher than 4.4.2 = cm 11. I tried blastgator's TWRP http://blastagator.ddns.net/twrp.html and also bumped=signed bootloader http://blastagator.ddns.net/bootloader.php - the 3rd one if you want to install CM 12.1 (there are also links to his XDA threads but not neccessary). PROPERLY check the CHECKSUMS !!! so you won't mess anything. So at 1st install TWRP (e.g. via FreeGee app) I got the latest. Then from the recovery flash the bootstack zip. then you can install any ROM you want and do not get that g2 verify trustzone Error.
