If you flashed CM kernel properly you wont be seeing Xperia logo, but FXP logo. You didnt flash properly.
I assume you have bootloader unlocked...

[Q] Xperia Neo V bootloop Problem

Hi..I have unlocked bootloader. I was previously on custom aosp ics based rom (4.0.3). Decided to go back to gingerbread (custom). Flashed night-elf kernel for stock rom v9.0 through fastboot. Installed rom through cwm. Rebooted the system. But it just stucks at the sony logo and reboots and the process goes on and on forever unless i pull out the battery.
Tried reflashing the kernel..no use! When i flash the kernel the phone reboots, the sonyericsson logo appears instead of sony. After that when i try to power on the device it gets stuck in the bootloop with "sony" logo rather than the sonyericsson logo. Help would be greatly appreciated!
Why double post?

ok ... I was earlier unable to boot into CWM (which I had installed via xparts) while the phone was boot looping ... I do not know why ...
I randomly flashed Suave kernel ... it was still boot looping but I was now able to enter CWM (comes with the kernel I guess - DoomLord's Full) ...
I restored an earlier backup I had taken ... and now it's working fine ... http://forum.xda-developers.com/images/icons/icon8.gif
with unlocked Bootloader and custom kernel ... cool! ...
oh yeah, baby ... Paranoid Android here I come!!!

as for as your problem i think you have not flashed JB kernel, their are so many kernels for JB choose one or read how to installrom from OP..
I would like to give a brief about locked and unlocked bootloader, it may help to other peeps
if you unlocked your bootloader it doesnt solve the bootloops, the main reason of bootloops are you have to use respected kernel for the respected rom, if you are flashing ics rom then you should be on ics kernel, same for ginger bread (GB) or jelly bean, you shouldnt be confused if you read the procedure of flashing the rom from OP,
whats wrong with locked bootloader?
if you accidently flashed any wrong mod or rom which is not suitable to your stock kernel you get bootloops, and you cannot restore backed up rom immediately because you have to reflash stock from scratch and then recovery, after then only you can flash etc, it is a very painfull process,
why to unlock bootloader..?
unlocked bootloader is like a muscle car , after unlocking you flash custom kernel which has cwm recovery per-installed , if you got any booloops you can easily manage restore backup, or you can flash custom rom which is compatible with flashed kernel, and you can easily switch kernels switch roms flash mods without worry,
this is explained in many ways and many times In xda, but peeps are lazy to search...
Please dont mind if my briefing is boring and useless...
thank you..

Why do you get Sony logo if you flash kernel... Are you sure you are fastbooting kernel instead of hotbooting?

boot problem after first reboot

Hi to all friends,I have a big problem.
I have neo with open boot loader, I had miui v4 Rom and yesterday tried to install optimax2.0 .I didn't like the Rom and I wanted to return to miui again with new install,after finishing aroma installation phone rebooted but it hanged on miui boot screen,I reinstalled again with complete wipe the phone boot normally but after first reboot it hanged again on miui bootscreen, I installed Xperia T v5.5 but it hanged again on first restart,
I don't understand why it hangs on first restart?please help me
Sent from my MT15i using Tapatalk 2
try a diff kernel first..if that doesnt work..then
start from scratch..check if this happens with official ICS..if it does, then its prolly kernel related i guess..reflash kernel..

I am not sure because I never used a miui Rom but if I remember correct most or all miui roms are based on cm.
And cm needs special kernels. So flash a proper kernel than the rom and all should be fine.

I usually use night elf v1.5 or 1.4 kernel, they worked with miui fine before this problem,
You mean I flash a stock Rom and then check the problem?
My bootloader is unlocked ,isn't it dangerous?

Ok learned something new.
Till now I only knew from miui roms that come cm based. Thats the reason I never tried one.
For me there is only one good cm Rom and thats the old good cm 7.2

What should happen?
Your bootloader stays unlocked. You will get stock kernel back but you can flash back night elf kernel.
If you flash stock Rom with an ftf file you can exclude the kernel and your currently flashed kernel will stay.
