OK so it seems a lot of people are having issues with boot loops when they are messing around with things. First thing. Your phone is NOT bricked or broken.
It's just unable to start due to something missing or broken. Don't panic, there's no issue. I did this the day I got my phone, and there was nobody to "help" as such, so I just fixed it myself.
These are the steps to fix a boot loop. If you do this correctly, it WILL fix it. But you must do it EXACTLY to the letter.
So here we go...
1) Turn off your phone. Unplug it from your computer etc
2) Hold down home, power, and volume UP. This will enter recovery mode. If you are using CF-Root, you'll get CWM recovery. If not, you get stock recovery. It doesn't matter which appears.
3) Choose to wipe user data from the menu.
4) Turn off the phone by long-pressing the power button.
5) Prepare ODIN on your PC by using task manager to kill any KIES processes, then open ODIN.
6) Put your phone into download mode (home + power + volume down)
7) Plug your phone into the computer using the factory USB cable. The leftmost box should go yellow and an ID number will appear.
8) Flash a stock ROM from those available in ODIN format, and the phone will boot correctly.
Alternatively, it is possible to flash VillainROM 1.1 if you are not comfortable in wiping via recovery, or if you cannot do so for any reason (corrupted kernel etc), as it wipes all users data when installing. Simply ignore steps 2 to 4, and flash VillainROM 1.1 via ODIN instead of the stock ROM.
Any questions about boot loops? Ask them here rather than making new threads.

TNX !
You're a great, I risked a heart attack!
noted with thx, I wish i had the correct instruction 3 days ago.
one more question, do we have to do one more step to flash the stock kernel after we flash the stock rom?
I plug the phone into the pc, but my drivers dont seem to be working it fails to be recognised. I tried with another Galaxy S II, and this phone does appear on the pc. Im thinking its because my phone isnt in download mode?
Any ideas?
Legend, thank god for this topic

You can also try just 1 2 3 & 4 and see if phone boots .
Its done just that for me as i try to clear a bootloop from a wipe to stock .

I had it myself and i was pretty happy that i uses the backup function from recoverymode cwm.
I would really really recommend that u use this BEFORE doing any critical changes to your phone.
I have a Boot loop after doing a full reset, It was installed with lightning rom
Now Odin doesnt recognize my phone, thats bacause i'm on other computer now (havnt installed the drivers jet)... i tried installing kies 2.0, didnt help... any suggestions?
Edit: is there no manually way to install you phone on you computer with manual drivers or something.... it's bacause odin still doesnt recognize my phone
EDIT2: I fixed my problem, for everyone that had same issue: http://forum.xda-developers.com/showthread.php?t=961956 => these drivers work
I have done all the instructions and flashed with a stock rom with odin but my phone still does the boot loop any suggestions?
Edit: fixed it with the villainrom, sorry for my post
thx!

If when connecting phone to your pc and your phone is ON then download the latest version of kies from samsung as this holds the drivers to connect to your computer properly.
If you are talking about when your phone is OFF and using ODIN then it should pick up your phone but you wont be able to flash until you are in download mode.
only other thing id add is try using a different usb port, one that is like a mainboard port not a hub.

Jep having same issues, not really an issue but i'm also stuck with the villain rom If i try to flash it with lighting rom i have boot loop
this all has started with a full factory reset, when I was on the lightning rom, the full factory reset caused my bootloop and ever sence the only rom that works on my phone is the villain rom
Exactly same happens to me
I have literom v1.0 I cant flash 1.1 or even flash stock rom without boot loops
Guys it seems there's an issue with some custom ROMs. VillainROM seems fine, as people can safely return to it.
If you cannot get a ROM to flash, then instead of flashing a custom ROM at the end of the process, ODIN a stock ROM after the wipe. That should fix the issue.
It appears some custom ROMs have a bug with wrong permissions, preventing the system from booting.

Yes, it appears lightning rom can't cope with a full wipe when it's running. VR is set up to work after the full wipe, provided you re-install it via ODIN

Yes, that won't work, as the ROMs are not compatible. You would need to get Lightning ROM to fix the issue
I followed the guide in the '[READ THIS]' thread and flashed a stock rom (i already tried about 10 different roms), but i still get a boot loop.
As i can enter the recovery and download mode without a problem and there never seems to be an error message after flashing i don't think that there is something wrong with the hardware.
Does anyone have an idea what i could do?
Also i somewhere read that you can fix pretty much any problem by using a riffbox.
Does any of you guys have any experience with that thing/ know if that could probably fix my problem?

Not necessarily.
Similar thing happened to me with KI8.
Was all good on KG1.
Flashed intratechs KI8 all good.
Flashed cfroot for KI8 had to factory reset to get root to work.
All was good at this point.
Flashed siyah 1.8 kernel all good.
CWM backuped.
CWM flashed % battery mod and stuck on Samsung logo at boot.
CWM restore still stuck at Samsung logo at boot.
Tried lots of things to fix but no go.
CWM restore of KG1 and all good again.
Still trying to work out what went wrong and will post the fix when/if I find out.

I have this problem too. For some reason, the only rom I can flash is Cognition 1.6 . The rest seem to just get stuck at the Galaxy S2 logo
Last week I flashed LD3 for my Galaxy S2 i777. Today I was going to flash CM9. Every time I tried to boot into recovery it just started the phone.
I figured I could use mobile odin to flash a new kernel and it would fix it. Like an idiot I used a Gingerbread kernel on my phone running an ICS rom. So of course my phone froze on the "Galaxy S2" screen.
I couldn't boot into recovery and freaked out because I couldn't boot into dl either. I ordered a jig but kept fiddling in the meantime. I found that if I hook my phone to the USB, wait for the battery charging icon, take the battery out, then hold the down button it would boot into dl mode. Then I had to put the battery back in before I clicked continue or else it just reset.
Ok, so got into DL mode. I grabbed the stock rom and kernel from XDA site and flashed them with Odin. http://forum.xda-developers.com/showthread.php?t=1286432 (can't post links yet).
The phone starts and setup mode begins. It shows the android figure and says click it. Now all kinds of errors pop up telling me different google services weren't working and force close. When you click the android figure it goes to setup wizard screen but nothing happens (except more android service errors).
Can someone help me out here? I've been at it 5 hours and searched this forum high and low. My thought is there are some ICS elements left behind in there it is trying to load, but I could be way off.
I still can't boot into recovery mode, just DL.

Did you do a full wipe before flashing the stock rom and kernel?
I did not do a full wipe. How can I go about that without logging into recovery? I'm googling that now but if you have linkage I would appreciate it.

dont need to wipe when using Odin/Heimdall.
To OP:
there is only factory recovery, no CWM, you could always just flash a kernal from the DEV section, get CWM, flash CM9.
If I flash another kernel wouldn't I still have the same problem? I'll go ahead and give it a shot. Any you recommend for any reason or other?

So let me get the straight...you're on unrooted stock right now? If that's true, you should:
1. Do a factory reset from settings.
2. Use Odin to flash the Stock with Root package.
3. Use Mobile Odin to flash either Entropy's DD or Siyah.
4. Use CWM to flash what you want after that.

recovery is in kernal. If you flash a kernal from the DEV section you'll get CWM recovery, then you can flash your CM9 that you wanted, after a wipe data/factory reset.

Yes, but if he flashes said kernel with Odin, it'll trip his flash counter. I'm just telling him the safe way to do it, Mobile Odin.
I've already tripped my counter. I have a jig that will be here tomorrow so I can use it to reset the counter.
I can't use mobile odin because I can't log into my phone. I can only use desktop Odin.
All the files I am digging up look like .zip made for cwm. Could someone help guide me towards a kernel I can flash from desktop?

Either Entropy's DD or Siyah. You can open the zip and extract the zimage; the zimage is the kernel.
I just tried using Syiah:

Flash the return to stock package from Odin again. Something must have gone wrong with it the first time.
well thats wierd. Sorry man but are you doing it right?
vol down and power. hold it untill the screen flashes twice.
I flashed stock 3 times now. I couldn't get into recovery before this (manually or with rom manager) and still can't. It starts like its going into recovery then just resets and loads normally.
Down is for dl mode, up is recovery.
I think the lack of ability to boot into recovery and the android service errors may be related.

Forget recovery. You shouldn't be worrying about recovery until after you get your phone booting.
New thought: maybe your download of the stock package is corrupted. Try to download it on your computer again. Download the one with root. If that fixes it, you can go use Mobile Odin to flash the Siyah kernel.
To get into recovery hold down both volume up, volume down, and power button and don't let go until recovery comes up.

I have been using the rooted. The fully stock won't dl. This started because I flashed a gb kernel instead of ics. Maybe I should try flashing an ics kernel instead of stock gb?
Ok, I made a schoolboy error and think I have softbricked my phone.
I just got it this morning and have rooted it through ODIN. I was going to install a ROM but when in recovery I went and used the Superwipe app and then rebooted (don't ask) and it is now stuck on the Samsung logo screen. I can boot into recovery but of course no backup as its been wiped.
I am downloading a Stock Official and going to install through ODIN. I assume this is the right way to getting back to stock and starting again to unsoftbrick my SIII?
Its the first time I have ever arsed up. Its not nice lol

I have the exact problem as you,but I couldn't flash the stock rom for my country..via Odin
Don't bother with superwipe, just wipe data/factory reset in cwm and of you really feel the need you can format system under mounts and storage in cwm.
Just make sure you have something to flash already on your phone before you do, and don't reboot after formatting system.
Flashing stock via Odin will fix your problem now.

Thanks. I dont usually format and have no idea why I thought it was a good idea to do it this time. I was going to mount internal storage through CWM and put the ROM on it but there was no option to mount it.
EDIT - All sorted. Thanks for the info
If you know how to use adb you could put the ROM on your sdcard through cwm.
Sent from my GT-I9300 using xda premium
Or if you're not comfortable with adb and got an external SD, put the external SD in your PC and transfer the cwm rom to that and flash it from external SD on your phone

Hey guys. I seem to be having trouble getting my Samsung Galaxy 4.2 out of it's recovery mode. I'll start with how I got here. So one day I was on my galaxy when the power ran out. I tried restarting it and found myself in a boot loop. So to fix it I tried flashing a kernel. All was well until I found out my wifi wasn't working. So I read up on some forums an people said the best fix was to just re-flash a kernel. So I did it again and it worked for a time. Then once again it said I was connected to the wifi, yet I couldn't actually get on anything wifi related. So again, to fix it I flashed a kernel. Now I'm really stuck. The kernel I flashed gave me a SG2 logo at boot, as well as a yellow triangle. Now whenever I try starting my SGP 4.2, it goes right into the recovery mode. I've also flashed a custom recovery mode to clear the Dalvik and normal cache, but it still does nothing. I've also tried re-flashing ROMS and kernels, but it still just leads me to this darn recovery mode.
Any help would be greatly appreciated.
Thanks in advance.

This was the same kernel that got me my CMW in the first place. . . I've tried both stock and custom ROMS, and they flash successfully, but it just takes me right back to my recovery menu after I reboot.

I am having the same issue. I verified my device beforehand and all the files. No matter what recovery I flash (stock or cwm) it will still boot into recovery. I've also tried flashing the stock rom, stock root rom and a custom rom as well as clearing the data and cache multiple times with no luck. Has anyone figured out a way around this?
