Default [Q] [Acro S] Flashing from Original 4.1 to 4.4

Sorry for maybe a silly question... but don't know how to go on...

Tried the instructions I found but had no success.

First of all I rooted it with Flashtool => Works
Than I installed CWM => Works
Copied 4.4.2 Beanstalk Rom and Gapps ins CWM folder on SD Card
Booted into CWM, formated everything, installed both zips, restarted => Black => no start => no possiblity to boot in cwm.
Flashed Original Stock rom with Flashtool again => Phone lives again.

Tried a second time => same results....

Where is my failure? Is there an other option to flash from 4.1 to 4.4 than CWM? Do I have to flash Kernel seperatly?

Many thanks in advance.

no kernel and rom can be flashed together

make sure you wipe your data, dalvik, and cache

do I have to unlock bootloader?
Only made root with the change of kernels as per instruction... but no separate unlock of bootloader? Is this maybe the failure?

me too.... till I found this instructions

wiki.cyanogenmod.org/w/Install_CM_for_hikari

So step by step the way is:

Root Phone with Flashtool

Unclock the phone this way: wiki.cyanogenmod.org/w/Install_CM_for_hikari
(Is unlock also possible with flashtool?)

Install CWM.
Boot into CWM
Format Data
Install Rom
Install Gapps.

Correct?
