Kernel nAa is for MiniCM7 ROMs (and based-on ROMs). So You can choose between f.eg. original MiniCM7 2.1.9, iROM v005, GingerXperiaRay.
The ROM You mentioned is for ALFS kernel
If You unlocked Your bootloader it will be unlocked, even if You flash stock ROM. But if You do so You will have to change kernel and root Your phone again, cause stock ROM works only on stock kernel

i can't delete system app. i used root ex and titanium backup but ...when i mount R/w it don't change .help me.
Theres no need to stock rom & downgrading... just flash the kernel...do a full wipe and install a new zip file containing new ROM
Sent from my E15i
help
but i think when downgarde i must back to stock room.now my phone drive 4.0 and i want back to 2.3.7.how to do fastest?i think if not phone will brick
U may be right...because i have not tested any ICS based ROM yet.
Which kernel are u using?
Sent from my E15i
Umm... Why dont you use PCC to get back to stock eclair. Re-root and flash gingerbread.
Simple.
No Risk
try using the SEUS..
you will get the original 2.1 back..
another one !!!Im trying to sound as polite as i can
the thread said its not for n00bs
You are probabely on nAa so just flash PrimeHD or MiniCM...
The ROM is still development...
thank to all.i could back to stock room by flash tool.thanks for your comment.

@LilleJohn if you are trying to install JB 4.3 remember that you can't use a kernel for JB 4.1.2. This will give you bootloop for sure
