Why try brick bug firm? 4.0.4 don't use. Is it rooted? If so flash neat Rom. Its 4.1.2 and has some good things on it. If not Root phone if not then flash through cwm.

It's not neccessary to wipe the preload before flashing neatrom jb as it will be automatically overwrite with the new preload data while flashing, so you can skip the step without much problem.
Edit : Just wiping data, cache and dalvik would've solved the problem you don't really need to flash again, but go ahead anyway.

As above flash Rom. But is recommend on neatrom thread to wipe preload many times. Why it comes up with that I don't no.

It's because preload will cause bootloops with other jb roms, but it usually happens when restoring a nandroid, direct flash has never caused problems for me, and I have had the same situation as OP where I got stuck at the android bootloader screen(the original default one not the NeatRom bootloader screen).

any another solution

Flash philz kernel first then do all the wipes preload too. I'm guessing you have done the wipe cache and dalv cache and fix permission after install complete and before reboot? ?

So you did
Wipe/factory
format system
Format data
Format cache
format preload
Flash neat 4.8
Wipe cache
wipe dalv
Fix permission
Reboot
If its still doing this boot loop after you fix permission do a factory reset mate. Then reboot it

Even though the problem was exactly the same, the only thing I had to do was a data/cache/dalvik wipe after which everything was fine , I also can't understand why the preload format fails(it shows some kind of ext4 conversion error doesn't it? ), andrewright you have suggested everything I would've suggested normally.
Edit : OP try an older non touch based CWM.
