The rom comes with its own kernel. No need to flash another.

Stuck on boot screen after NEAT rom install

I did everything I was supposed to do, first succesfully rooted the phone. Then I put the zip file with the rom into the sd card and then went into recovery mode, installed file from zip and it said success in install so I chose to reobot and now it hangs there... Any one can help me out? I'm scared...

A bit more details. What phone model? What were you trying to flash? Where does it hang, on the Samsung boot animation, or in the recovery?
Sent from my GT-I9100 using Tapatalk 2
Galaxy s2 international (gt 19100). It hangs on the boot logo, which now is a yin yang with ics on it, I guess this is a NEAT thing. I can go into recovery mode, it just hangs if I try to boot normally.

The yin yang boot logo is actually the kernel. (Siyah)
You should probably try a factory reset/wipe data from recovery. This will alleviate 90% of boot loops and stuck on boot issues.
How do I do that?

You just said above you can boot to recovery... Once you are in recovery mode, can you not follow the recovery menu system to find the wipe data/factory reset option? It should be pretty straightforward.
I'm not running Siyah, so I don't know what the exact menu item is called in the recovery image that is in that kernel.
I tried that but it still does the same thing... any other tips?

Actually, let's take a couple steps back.
What model phone do you have? It's printed on the label under your battery.
it says model GT-i9100
ssn i9100GSMH

Ok. Are you SURE you're doing a wipe data/factory reset when in recovery? If so, then I'd flash a stock firmware, full wipe again, then try the Neat ROM install again.

Find all you need to know here.
As an easy rule before installing any new ROM (that isn't an upgrade from a previous version ex. Cm10 builds or if otherwise stated ) wipe data , cache and dalvik cache , which is under advanced

what he is trying to say is that you should flash the kernel AFTER you flash your ROM
the ROM you chose is [CM10][Jellybro] i9100 Nightly Kangs, yes?
anyway..
here is what you should do
1. flash your rom
2. flash gapps for cm10
3. flash a kernel [an example of which is Dorimanx Kernel]
if you are still confused on some terms, please refer here
I hope this helps
EDIT:
you should root your phone first
You know, after flashing a new rom booting may take some more time, at least a few minutes. Have you been waiting enough time?
First, check md5sum of ROM [what Saywhatt wrote a few posts back]
a. If you are no longer in recovery modes then you can get a kernel [tar file] Flashing with Odin.
If your phone then starts normally, then flash the ROM you want through CWM.
*** wipe data / wipe cache / wipe Dalvik cache / format system in mounts and storage / flash ROM from sdcard***
b. If you can get into recovery mode, not flash with Odin, but do these same steps;
**** wipe data / wipe cache / wipe Dalvik cache / format system in mounts and storage / flash ROM from sdcard***
PS. If it fails in step a first flash stock ROM with Odin
sorry for my bad english

Bootloop with samsung based roms

Good day all,
I have a problem with samsung based roms. When i flash them, the phonegets stuck at the samsung logo. I tried a few JB 4.1.2 rom from samfirmware.com. And today i tried to flash omega rom v23. With all of them i get the bootloop. I've already tried the newest siyah and philz kernels, but it didn't help.
This is what i do when flashing a new rom: wipe data, wipe cache partition, wipe dalvik. Then flash the rom.
I have no problem flashing aokp roms. Because i have flashed omega rom v12 aokp milestone and it starts normally.
Can anyone help me?
ps. when i do data wipe, i get "E : format_volume : make_extf4fs failed on /dev/block/mmcblkl1p2
DOes this have anything to do with the bootloops?
Anyone got this problem with Samsung based roms?

Try this download these 2 wipe scripts Rom Wipe / Nuke script Then for good measure this too Kernel Wipe and save files to sd card.
Then go into download mode flash both files, then any Rom you wish immediately after, hope this helps.
Do a full wipe, install the rom, reboot into Recovery, install fixed Philz-kernel (or Siyah), and reboot. In my case it worked, but I agree it's pretty difficult sometimes.
The first boot takes very long by the way.

I have similar problem, no error popups though...
after full wipe (even using cleaning scripts) and installing new rom (with recommended kernel) my phone bootloops on splash screen...
I only found out that stock roms work, and most of custom fails - I managed to launch ReVolt once, failed any other time even with the same method. Furthermore ReVolt caused my simlock to come back (and this is actually a different story - tried every method to unlock my phone but only with Galaxy_S unlock and only on Gingerbread worked)
Could it be casued by any "deeper" ingerence of the provider i got my phone from? It's Orange, Poland
Thanks for any tips

The same method is followed for both CWM and TWRP but dont know why it doesnot delete in your case. Coz if you are doing a advanced wipe it will surely delete boot files for sure.
