1.- Flashed bootloader from N9005XXUENA6_N9005OXXENA5_N9005XXUENA2_OXX (Leaked Kit Kat version)
2.- After reboot, flased bootloader, CP and CSC from the same version (N9005XXUENA6_N9005OXXENA5_N9005XXUENA2_OXX). Flashing bootloader again might not be necessary, but this is how I did it, and how it worked, so I cannot confirm otherwise
3.- Flased AP from N9005ZHUBMI7 (Honk Kong version)
4.- Entered recovery mode and wiped system, cache and dalvik (just in case)
4.- Flashed autoroot (n9005-cwm-recovery-188.8.131.52-kitkat(0113).tar)
5.- Flased CWM recovery for KitKat (n9005-cwm-recovery-184.108.40.206-kitkat(0113).tar)
6.- Installed the latest version of SweetRom (SweetROM_V7.00_NA6_4.4.2_N9005.zip) from this thread: http://forum.xda-developers.com/show....php?t=2487425
So long it seems to be working correctly, battery consumption has increased, but this seems normal every time I change my ROM. Thanks again for all your help, and hopefully this will help someone else resolve the issue until the official version for the HK 16GB version is available.
