Which version of galaxy s2 you have? You can see it in phone information at the bottom of your settings as modelnumber.
Maybe you'd try to flash a rom without kernel first, cause it's likely you flashed the wrong kernel.
So at least your phone will start running. Afterwards we can talk about further stuff

Too late to backup data now. You should have done it earlier (unless you've already done that). Next time, use titanium backup to backup and restore app+data. You could try flashing back the original rom you had. Your phone should reach to 100% when flashing anything, so in your case, this seems to be a big problem.

If you are stuck on siyah kernel, this could be a problem with the rom you are installing. What version of android are you trying to install?

update
Thank you guys for your response i did manage to backup my data and did a full data wipe then installed neat lite rom and it worked for me
now the phone is working fine i guess it was a conflict between rom and the kernel thanks alot for you response again

Help. My galaxy ace keeps restarting itself.

Recently my phone has just been restarting itself allot and it is getting very annoying. The phone would just be sitting beside me and the next thing I see is the Samsung boot screen. It never restarts when I'm using the phone. Just when it's standing by.
I was thinking an emergency firmware recovery through Samsung kies might work. But I'm afraid of losing my apps. If I do this will the apps be removed or will they be there just as usual?
Current android version that i have is gingerbread 2.3.3
Thanks for any help or advice in advance
For me i would back up all my app to the computer (music,videos,pics,apps etc.) and then update.

i doubt there would be firmware recovery available from kies [who uses kies this days].. as your last firmware installation was total there wont be recovery....
if you choose to root [your choice]... you can backup your apps and then try to do anything.... if you just need to backup apks then use AppMonster.. this will just backup apks not whole data with them
try to flash stock firmware with odin again
This hasnt been brought up recently since a lot of the active users here uses CM7 nowadays, so I'm guess that this is simply SOD(sleep of death) caused by wifi.
You might resolve this by turning off the wifi when ure not using it.
When I turn WiFi off, it still restarts itself, all the time

root --> backup apps with titanium backup --> backup sms --> flash latest stock again through odin --> root --> restore apps

Last time I tried odin, I bricked the phone, I don't really want to try that again.
If there is a full step by step guide to flash cyanogen mod for the ace with odin, I'll give it a try

no cyanogenmod through odin
only if you flash cwm with recovery then you can indtall custom roms
======================
SGSII styled rom
for galaxy ace
======================
The Serious MOD V0
for galaxy gio

made by Robinandroid
Solved with cyanogenmod
I gave cyanogenmod 7.2 a go on my ace.
So far no problems! I will post if I come across any sort of restart. But so far it's great.
Thanks for all the replies you guys, I really appreciate your help!!
Phone restarting with cyanogen mod
I flashed cyanogen mod on my phone and there were no problems until last week. The phone hasn't been restarting just not waking up. Then I have to pull the battery out to get it to go again. My phone can't go 24 hours without we having to restart it once or twice .
Is there any way to fix this. Thanks

I think relflashing again will solve this.

thanks for your suggestion but I've already tried reflashing it. through Odin and clockwork recovery. Both giving the same result.
I am following the instructions to flash exactly but still restarts.
sorry for your problem man, but i didn't face such problem.. i'm flash and using almost all of custom ROMs available from various devs.. use them at least a week and its nice..
try flashing it again using cwm 5, may be it will solve your prob.. currently i'm using nims11 infinity v2..
CWM5
Where do you get cwm for galaxy ace. I have version 4 and that might be causing problems with the updated cyanogenmod.
Thanks for all your help and suggestions!
Is the installation just the same as other versions?
boot in recovery mode and install update from sd?
If I can get cwm 5 from somewhere, I'll give it a go!
If I have cyanogenmod already installed with cwm 4 can I install cwm 5 and not worry about it, or will I need to reflash cyanogen again?
try flashing cwm 5, n then, flash cm7 again..

You flashed cm7.2 with cwm4??Flash cwm5 and then try a reflash of cm7
I've flashed cwm5 then wiped the phone using it then I flashed cyanogenmod, (the one from the xda forums at http://forum.xda-developers.com/showthread.php?t=1263292 )
There was no problems, I restored all my apps using titanium backup. Then just a few minutes before this post I came to my phone and it wouldn't light up. (Sleep of death I think you call it?) I had to pull the battery out to get it to go again.
It was plugged into the charger at the time
Bluetooth was on
Wifi was off
Mobile internet was on
Before I locked the screen it was syncing gmail. (This probably isn't a problem)
I have the 'all apps movable to sd card' thing checked in cyanogenmod settings to.
Any suggestions?
Thanks, Chris.

Flashing back to vodafone stock rom from resurrection v.9.2

Hello guys,
I must admit I am an absolute noob a bit out of my depth and panicking a little bit now. I successfully rooted and flashed my phone with a custom rom, the resurrection ics v9.2 however I wanted to go back to stock vodafone rom. So i downloaded BUKE1 vodafone firmware and flashed it using ODIN. Now my phone is stuck in a bootloop with the galaxy S II logo repeatedly appearing. I have just left it as is as I am now too scared to do anything :/
Any advice on what I can do? I know you guys have been over this a million times but I am freaking out.
I have read the boot loop thread above and it says to flash a stock rom using odin but that is what I had already done...
Any help would be greatly appreciated.
Jake
Try wiping all possible things in recovery.
And don't worry, atleast some1 pro will help you to get your phone to boot, also can you get to recovery and download mode

Hey thanks for the quick reply, I can get to recovery mode definitely. I just went in and wiped user data / factory reset option. Do you think I should try flashing a different stock vodafone rom?
Ok after wiping user data it now appears to be fine. I'm sorry for wasting your time.
it is recommended that you wipe everything after flashing in order to avoid boot loops or similar errors
glad it worked out for ya

Bootloop even after full wipe many times

Okay first of all, my phone was working fine but suddenly i had to use the GSII_repair app from the market
since my phone cannot suddenly detect any simcards. I used the 1-2 steps in the app since it said i had to reboot.
Then after that It went to a bootloop, tried flashing stock ICS rom it works but the phone suddenly turns off everytime before the S logo finishes its animation! what could be the problem?
may be soft brick

1.Flash stock kernel,put in PDA block of Odin.
2.After that Flash all 4, bootloader,PDA,Phone & CSC same time.
Get a 4-file firmware. (PHONE, PDA, APBOOT, CSC)
Make sure you're not using a 4.0.4 leak - use a 4.0.3 official firmware.
If this doesn't work, flash a custom kernel and wipe /data.
If it still doesn't work, flash a custom ROM (CM9, CM10, AOKP). Once you've got that up and running, return to TouchWiz if you wish.

Can you get into cwm recovery ?
Sent from my GT-I9100 using xda premium
Yes and im talking about the first boot screen.
The one where we see the Galaxy s2 logo.
Not the S Animation.
I'm stuck, tried PITT,departitioning , kernel, pda ,csc .
Could the GSII_repair kit messed up something much more?
Got into the S animation on ICS stock but phone shuts down even before the S animation has finished appearing.
And I had to have the usb plugged into the phone just so i can power it on.

Phone booting in loop and cannot unbrick

Hi !
I am using a Samsung Ace S5830i since 2 years now with a custom ROM : Ace-i-Sure 12.0, all worked properly.
Yesterday I installed an app, I do not remember which one but I think it was a game, then my phone rebooted and looped on the boot animation.
I am used to unbrick my phone and change ROM so it did not scared me.
I tried to flash the stock ROM I used to flash everytime my phone has been bricked. Flashing went OK but my phone kept looping.
I tried to wipe data/factory reset but nothing changes.
I tried with another stock ROM found here and nothing changes either.
Do you know what might causes this problem ?

http://www.youtube.com/watch?v=3d7AS3Is4bk
and no it is not hard-bricked...
Hit thanks if I helped
I tried all the solutions you gave me but nothing works, I do not understand...
I might buy a new phone, but I ain't got much monyer, I can spend maybe 100€ or 200€ maximum
Does your phone enters into download mode and detected in odin?
What's the status during flashing ?
Then try the flashing methods on another pc.

The problem seemed to be the recovery, i didnt have an alternative recovery in the sd card nor any card reader but i needed my phone asap so i tried restoring a nandroid backup which seemed to workout for the stock firmware. Once i was restored i quickly downloaced another recovery (TWRP) and flashed it with mobile odin. I tried flashing custom roms again and it all seems to work fine now. hope it helps
