Default [Q] Downgrade from CM11 to Jelly bean 4.1.2

Hi guys im an xperia s LT26i user and i have an unlocked bootloader. Im currently running cm11 rom by raymanfx. The last time i tried to flash 4.1.2 rom i did NOT wipe system and i ended up getting a bootloop and soft brick. So if i am running cm11 and if i want to downgrade to 4.1.2 do i need to wipe system, data, cache and dalvik cache? cache and dalvik is a must but if i wipe system and data will it work?

You should make a full wipe probably everytime you switch your ROM. So:

- factory reset
- wipe dalvik cache
- format system

So your entire system is clear and if this don't work flash latest Stock ROM first and then the ROM you'ld like to run on your phone :P
Devices:

- Sony XPERIA Sola

- Sony Ericsson XPERIA Ray

- LG GT540
