[Q] Galaxy s2 stuck in boot mode - Galaxy S II Q&A, Help & Troubleshooting

Hey all, so I have a galaxy s2 (as you may have guessed) and had a friend root it for me a while back with lightning rom ... Not sure if anyone can help me here ...
I am giving the phone to mum, so went and did a factory reset on it, and it apparently ate the OS because it is now just stuck rebooting itself, it wont actually load into the OS at all.
I've gotten it into recovery mode, but nothing i do seems to work, it just says it can't find files, or sits on a screen with a pretty little icon.
Is there any way I can download the OS again, or somehow get it back onto the phone?
Cheers for your help in advance!

Find a rom that is installed through odin, either a stock ki8 rom or a modded one, there's plenty in the dev sections.

do you have CWM installed if it is then mount usb storage from CWM menu push the ROM in your mobile from your PC. I would recommend this ROM
http://forum.xda-developers.com/showthread.php?t=1290468
then install as the instructions given on the first page
P.S odin works good too, your choice

There is a sticky just at the start page called bootloop. Take advantage of that.

[Q] SGS2 Won't boot properly - not a boot loop [problem solved]

Ok, here's the deal:
Rooted the device, everything was a-ok.
Installed Clockwork, everything still a-ok.
Tried using mod manager to install Cyanogen nightly 9, phone rebooted and the progress bar for the mod install wouldn't move. I waited for a while and eventually manually turned the device off as it wasn't making any progress.
Ever since, it won't go past the screen you get at the beginning (w/ the yellow sign indicating an unsecured rom). It just stays there forever.
What I have to work with:
- Clockwork Recovery is available.
- The device is recognized by Odin when in download mode.
- The device is not recognized by the computer/Kies.
What I've tried:
- Followed the instruction for boot loop w/ both stock rom and Villain (no dice).
I'm sorta freaking out now. I have yet to see anyone having the same problem online and I really hope it's not bricked - a 600$ paperweight...
Is there something else I can try? Is it possible to flash stock PIT/Bootloader/PDA/everything else? If it is, would it fix the problem?
Please just point me in the right direction.
Thank You,
Edit: In recovery mode, the following error appears:
- Can't access to "/system/csc/VMC/system/"
Edit: In download mode, the current binary is set to "Samsung Official". Therefore I think this isn't the problem.
Edit: OMG OMG holy crap. Problem has been solved. Got a friend who had the same phone from the same provider to tell me what the firmware for the phone was. Downloaded it. Installed it w/ Odin. I almost turned religious when it booted a bit slower than what I remembered. It works well enough now, although I will probably go exchange it for a new one ASAP, before my warranty expires.
If anyone has similar problems. Don't panic and re-install stock firmware.
Cheers Folks!

Did you read the answer ???

Look online (samfirmware), ask friends or on forums for anyone who has the SGS2 w/ the same carrier in the same country and try to find the firmware version (I9100***** - the stars are letter codes). Then just download that firmware and use Odin to install it.
If you can't find it,you presumably could just flash any stock firmware and it might work (or it might make things worse, try at your own risk)

The progress bar not moving is a known issue with the CM7 Recovery. All you need to do is wait for it to say that it's finished. There is nothing wrong with your phone and no need to return it. You just cancelled the CM7 install part way through which meant not all required files were installed on the phone, causing it to not boot.
As for it taking longer to boot into android after the odin reflash. That's because it has to build up it's dalvik-cache again. This is completely normal any time you install a new rom. It only happens on first boot of a rom.
So again, no need to return your device and feel free to try CM7 again. Just remember to let it finish even if the progress bar isn't moving.
Ahh. Ok that makes sense. This ought to teach me to read before screwing around w/ my phone.
I wanted to exchange it because I wasnt sure i'd still be able to install official Samsung firmware updates through Kies.
Suppose an official 2.3.4 firmware comes out, would i be able to install it through Kies?

Yes, as long as the firmware you're flashing is the same as the stock version that came on the phone. And even if not, you'll get the kies updates for whatever region firmware you did flash onto the phone.
I see. Thanks a lot!
Is there any danger to flashing firmware from a different region than the one youre from?

I need urgent help, did i brick my phone

ok so yesterday i rooted my telus fascinate and i was going to isntall the MIUI rom. Following a guides instructions i installed rom manager and did a clockwork mod recovery, i then put the rom on my root file of my sd card and tried to install it through the "install rom from sd card option" on the app. Problem was i only got into the stock recovery mode and not the clockwork one it aslo gave me signature failures. I then followed the guide of this video:
http://http://www.youtube.com/watch?v=Q7xV0yE9ZcA
when i installed the kernel everything went fine but then after i got into CW recovery and installed the rom my phone booted and it just kept repeating the normal splash screen (it said galaxy I9000 instead) followed by a screen that said something like cryogenic mod. I got freaked out from here and tried to install stock kernels to get my phone running. As of right now my phone will boot but only stay on the splash screen. I can not access recovery mode. I really need some help, thanks.
these are some of the files i used:

thanks
the links are broken. Did you install a rom / kernal specifically for the telus fascinate?
i believe it could have been for the galaxy I9000,
ill try to fix the links btw
update*
i managed to get it into clockwork recovery mode by holding the dam buttons for a solid 5 minutes, after doing this i pressed factory reset, now my phone is stuck saying:
-- wiping data...
Formatting DATA
0_0' im not having a great day
http://forum.xda-developers.com/showthread.php?t=1227807Until I know what version miui and kernal you are trying to flash, it's hard to help. It definately sounds like your phone is soft bricked tho.

The rom you are trying to flash is for a i500 fascinate. I suggest taking the time to do alot of research before you turn the phone into an expensive paperweight. Read this link!!
http://forum.xda-developers.com/showthread.php?t=921285
K well i ran that rom and it works now but he only problem is i dont have any cell service, do you know how to fix that. I know that you are probably laughing at my mild retardism at this subject but i am a big noob. As for what you said in your previous reply is their an MIUI version for the fascinate from telus because i basically rooted my phone so i could get this rom.
thanks
Update*
i followed the instructions on the link you posted and chose the rom for MIUI I9000 as the one i was going to install but when i istall zip from sd it only says installed correctly and then when i reboot it keeps changing from the sgh-t959d to the galaxy s cyanogen screen
yea your boot looped now. I would run the rom that worked just install the compatible radio and kernal for it and you should get cell service back.
ok thanks i got all my cell service back and i got the MIUI rom to work. Now to just ry to remember all the apps i had
Your welcome...glad you got everything working!

Well first off even if it did work trying to flash anything from kies would leave you in a bootloop. Running a custom roms kills the ability to update that way without going back to stock. Doing a factory reset does not remove a custom rom from the device. Reflash the rom and then boot up.

[Q] Help PLEASE!

Hi,
i recently installed CM on my samsung s3 using the installer. All went all. Until after about 2 weeks, the phone was not charging correctly. So i went into the settings and performed a factory reset. No i had not installed or used clockworks to back up my phone. This left my phone in an unusaul state, where there was no home screen, i could not access my apps, although i could access the quick settings tab. Moving on....i followed a guide to try and restore my phones orginal rom using odin. According to odin all was successful, however my phone was stuck in a boot loop and so would not continue into phone. i read up and saw if i installed clockwork i could wipe cache and this might help the phone. so i installed clockwork using odin again. however when i try and access clockwork through the recovery mode, it only loads into odin mode? so i am unable to load clockwork as well i think. I am very new and this and i know i have probably made many mistakes but we learn through our mistakes. So my question is: Could someone please help me get my phone back to its orginal state!? Thankyou very much for anyone that can offer their time and help,
Nick

[Q] Samsung Galaxy Tab 2 7.0 [gt-p3113][os deleted][stuck on old cwm recovery]

I'd like to start this thread in establishing that I am not familiar with how all this works, nor do I have any idea how to fix it, which is why I'm here. I only know the system info, such as version, firmware, etc.
In attempting to add cyanogen mod on my already previously rooted Samsung Galaxy Tab 2 7.0 gt-p3113, I watched a video that directed me to install clockwork recovery and root in a single bundle using Odin, (which I successfully did). I then proceeded to install cyanogen mod while in clockwork recovery, which it then told me to factory reset wipe all data before doing so. After going to the "main page" of CWM and resetting the device like it told me, I then went back to install cyanogen mod, only to have it tell me that CWM is out of date. I tried rebooting the device, but it would take me back to CWM, which im assuming means I deleted to OS on accident.
After all that, I finally concluded I'm stuck on an old version of Clockwork Recovery with no OS installed. I can access download mode, however when I'm not in download mode the device automatically boots up to the old version of clockwork mod, and I'm stuck there.
As I have no idea how all this stuff works and did pretty much everything from a YouTube video, I'm hoping a more experienced developer can help fix the problem and somehow help me regain use of my tablet. At this point I don't care whether I can get cyanogen mod installed or not, and I would appreciate all the help I can get.
Thanks

Well, I would say that may be a bigger problem ! Now what I think better for you would be trying to flash the stock ROM over to the device again I am sure you have your hands over the flashing. So head over to the sammobile/firmware section and try getting the stock ROM downloaded and flash it over your device.
