[Q] SGSII stuck on boot after flashing kernel - Galaxy S II Q&A, Help & Troubleshooting

Hi all,
I think I F'ed up. So I've just rooted my phone and was trying out flashing a kernel for my i9100. However after the flashing the first kernel my phone got stuck in boot. I've tried flashing severeal other kernels compatible with i9100 (via odin and mini-usb). They all install, however my phone still gets stuck at the boot screen. I'm using anrdoid 4.1.2.
Help I don't want to lose my phone!
Thank you!
EDIT:
Also, I think perhaps my ROM might be damaged? I tried the backup recovery in CWMR, but the recovery crashed halfway as my battery dropped disconnected (didn't have the back cover on). If I try to restore the backup now it says: Error while restoring /system!

[Q] Stuck in CWM

Hi all,
my prime is stuck on CWM. I haven't changed the ROM in anyway, but did install CWM and used it to back up the device. I did a factory reset and now it just keeps booting into CWM. I have restored my backup, which appears to have worked, but still stuck in CWM.
It's on ICS
Any ideas ?

If you can't get ADB to work, use these drivers: http://forum.xda-developers.com/showthread.php?t=1426502
My device was bricked for several months before I picked it back up and found these working drivers.

Just use One touch upgrade. Connect your phone to your computer and then start the upgrade. Your devices will have an hard- reset, and the cwm will be deleted.

Every time I flash stock rom with Odin the phone gets stuck at boot

So I've got this issue I never had before.
It started happening after I screwed something up with the EFS I think.
I was flashing some custom roms after the 4.3 official update and then tried to go back to 4.1 official.
Had the no network problem, but fixed it flashing the vodafone stock 4.3 official again.
Reading all the stuff about EFS confused me, and I deleted the EFS folder and copied an old backup (or so I think, because I'm not sure. I had a EFS backup on my sdcard and extsd I think).
I no longer have the no network issue, but everytime I flash a stock rom through Odin the phone gets stuck at the samsung logo, so I have to root the phone and install TWRP using Odin and then wipe. I know this way fixes this, but what I'm looking for is to fixed the problem completely so I don't have to install a custom recovery or root after using Odin to go back to official samsung rom.
Any ideas?
What should I do?
Maybe the phone gets stuck at the samsung logo because all of this EFS thing, but, like I said, I no longer have the no network issue.
All I want is for the phone to boot normally into the setup after flashing a samsung rom using Odin.
It just gets stuck every single time since I had this problem with the EFS, when before this never happened.
try to install the rom in recovery mode

I had this problem before (flash 4.1.2 in current 4.2.2 by odin), here's my solution.
Maybe you can install your ROM in recovery mode. (CWM based)
Remember to wipe completely before installing

I can flash custom roms through TWRP, but what I'm looking for is to be able to do so again through Odin without ending up stuck at boot always and having to wipe through TWRP to be able to boot properly.
Any ideas?
I'm sure there must be a fix so I don't get stuck at the boot screen after flashing a samsung rom with Odin.
I know the trick wipe factory reset but what I really want is to simply avoid getting stuck at the boot screen after flashing a samsung rom with Odin.

Factory reset is also available in default recovery as well, then what is the issue? Flash then boot to recovery do factory reset.

Thanks.
I'm just trying to find out why my SGS3 now gets stuck at boot when before it never happened.
I'm hoping there's a way to fix it and go back to before, when it never got stuck at boot. There should be a way I guess.

You flashed stock firmware with Odin, was the flash successful ?
If you need to use recovery, flash TWRP or Philz, CWM is not updated anymore
Try flashing one of the firmwares in this thread.
yeah as far as odin was concerned the flash was successful and set the phone to reboot, but it still just hung at the samsung logo, and right ok im a bit out dated using cwm then it's been a while :Lthanks for the links i'll give it another crack now
thanks again

i've tried flashing CM and MIUI using the two recoveries you linked, still no joy. The download links for the firmware doesn't work but i found an equivalent that also has bootloader, csc files etc and still no joy, odin does it's business and says in green pass at the end of it all but it still hangs on the samsung logo, even when i installed miui, it would install all as planned, but then on the reboot it just hangs at the MIUI logo.
i'm lost completely i've never been defeated by a phone :L

Bootloop after Crash [ArchiDroid 3.1.5]

Hey guys,
I have a problem with my Galaxy S III I9300. I have been using a CM 13 rom for some months now, which has worked perfectly fine untli yeserday.
My Phone crashed randomly, which happens sometimes, but after this crash it was stuck in bootloop. I tried to reboot, no result.
After restoring a backup it worked for some time until it suddenly crashed and stucked in bootloop again. Same with factory reset.
I have even flashed a new rom ArchiDroid , via CWM, with the same result.
I hope you guys can help me out with this problem.
Thank you in advance,
GeneralD
Have you tried flashing the latest stock ROM with Odin, performing a factory reset from stock recovery, and then using the phone for a while to verify functionality?

Definitely. Flash to stock should be the first thing you do if your phone goes into bootloop.
OK, I flashed the stock rom & recovery and did a factory reset. Until now everything is working fine, except the "Not registered on network" Error, which I have now
Any solution?
Does the phone show the correct imei? Have you tried manually searching and connecting to a network?

If all you did was flash a stock rom you should be ok to do what you like to it.
