My HTC One with KitKat installed!

I only want to share how i did. I'm using 'Android Revolution HD 40.3'.

1# Download TWRP 2.6.3.3 & the rom from 'Android Revolution HD'

• rom - http://android-revolution-hd.blogspot.com/p/android-revolution-hd-mirror-site-var.html
• recovery - http://forum.xda-developers.com/showthread.php?t=2416431

2# put rom file in the phone

3# Flash recovery TWRP 2.6.3.3 
put the .img file in your 'android-sdk/platform-tools/'

type in terminal:

./fastboot flash recovery <recovery_file_name.img>./fastboot erase cache
./fastboot reboot-bootloader 

4# install the rom from the recovery

thats all.
