[Q] Stuck on a boot loop - Galaxy S II Q&A, Help & Troubleshooting

Hi
I just flashed my GS2 for the 2nd time via Odin and everything went fine, no errors or something like that.. The problem is that now i'm stuck on a boot loop.
The phone keeps restarting at the first boot animation and i can't do anything..
I've tried to reflash with other roms, stock rom's, stock kernel but nothing works..
Can i have some help please? :/
Thank you
EDIT: Just noticed that this is not the right section for posting this sort of things.. Can i have it moved to the right section please? Thanks
EDIT2: Forgot to mention that this started to happen since i did an hard reset using the *2767*3855# method.

Turn off the phone -> Hold volume up + power + home -> in recovery wipe data/factory reset and wipe cache.
That worked for me when I was locked in a bootloop the other day at least, can't say if it'll work for you though :/

This worked for me.. Many thanks!

Im still getting this!
I can flash a rom and it reboots, so I boot upinto recovery and wipe data and cache and its still mucing up
please im going insane

I fought with this BIG time.... it did not matter what I flashed or reset, I was constantly stuck in a boot loop.... but then Chainfire said this, took me a couple of tries but it worked.... I did not full understand the gist of it, but the end result is my phone is up and running....
remember, once you flash the stock rom, you have to do the recovery reset (should be blue instead of orange).
I will post the link in a second, I have to find it, lol
"Villains ROM doesn't include kernel AFAIK (yet!). Again, don't fear. This is a Samsung device, unless you botched up flashing a bootloader, you aren't going to break it. It is epically difficult to break Samsungs by accident.
See this thread http://forum.xda-developers.com/showthread.php?t=1075278 for some stock firmwares. Do a full wipe after flashing (from recovery). I advise the XEU KE7 variant."

Possible fix
Hi,
I had a similar problem and following exactly Intratech's post #108 from the following thread solved my issue:
http://forum.xda-developers.com/showthread.php?t=1075278&page=11
The three file install went OK and then I was able to install the latest "one file" tars as usual.
Intratech's #108:
I assume you know how to use Odin. Download the firmware from this link and extract everything to one folder: http://hotfile.com/dl/116656855/2ccf2f4/I9100XWKDF.rar.html
The password for the file is: samfirmware.com
Start Odin and put these in the following
PDA: CODE_I9100XWKDF_CL170898_REV02_user_low_ship.tar
CSC: GT-I9100-MULTI-CSC-OXXKDD.tar
Modem: MODEM_I9100XXKDJ_REV_02_CL996627.tar
Forget the rest of the files. DO NOT SELECT A PIT FILE AND DO NOT TICK REPARITION.
Put your phone into download mode and connect the usb cable. When the Odin box turns yellow press flash and wait until phone reboots. The first boot will take a while... be patient.
It's 2:58am here so I'm off to bed. I don't know how to make this simpler for you.

[Q] Endless boot cycle after flashing Litening Rom

Ok so my Galaxy S2 i9100 arrived today!
I began by flashing VillainRom 1.1 and then decided to give Litening Rom a try, fired up odin, selected the rom and hit start. It completed but instead of rebooting the phone has gone into an endless reboot cycle, just showing the boot screen over and over.
I pulled the battery and am reflashing now, it that doesn't work where do I go from here?
Cheers
Edit: Nope, still not booting up properly
You go to the OP of the VillainROM thread and read the words in big red letters.

So if I reflash VillainRom then enter recovery, wipe user data and THEN install Litening Rom it should work?
Or have I permanantly screwed my phone?
Edit: So I reflashed Villain and it booted up fine, I went into recovery as suggested and selected wipe user data. After that finished I held the power button down until the phone turned off, then booted into downlaod mode and flashed litening. Same problem occurred, I tried this two more times but both to no avail.
What am I doing wrong?
Cheers
flash to stock KE7, then boot into recovery, select wipe data/factory reset and wipe cache, boot into download mode, flash lite'ning rom, then then it should work 100%.
oh and btw, as long as you can boot into recovery/download mode, your device isn't bricked.

Sorry to seem like a noob here... but a few quick questions, What does KE stand for exactly and where can I downlaod a stock version from? Cheers
KE means after KD but before KJ ,just as A is before C .

Worked brilliant, thanks
I had a similar problem, but I solved it by just booting into recovery mode, wiping data(/factory reset) and dalvik cache and then just flashing then ROM through "download" mode.
I did not have to flash any stock ROM prior to that. Just these two simple steps!

[Q] stuck on boot logo

ok im stuck on my boot logo for my motorola droid 2. its a liberty logo, no the original M logo, ive held in x when it starts up and then it takes me to the triangle and then i hold the search button down and then it takes me to a menu saying this:
reboot system now
apply sdcard:update.zip
wipe data/factory reset
wipe cache partition
ive already tried just rebooting it and then it does the same thing again and just gets stuck at the boot logo, so please help. thanks!
Have you tried pulling the battery out for about 15 seconds?
See if that clears it up.
with it unplugged and turned off?
Yes Sir. Unlug it and turn it off.
yes i just did that and it didnt work, its still at the boot logo, the only thing i can do is go to that recovery menu that i said about in my 1st post, but idk what to do when i get there?
Try wipe data/factory reset.
Obviously you're gonna have to tweak your settings again.
okay, is there anyway i can get my settings back like a recovery? or something
Well, you might want to head in to the Droid 2 forums to get better responses related to your phone.
Here is a link to start with.
As far as recovery goes, I don't think you have a custom recovery installed. Sounds like you have a stock phone. So, there's no way of backing your stuff up.
i have it rooted and a rom on it but nothing custom, but thanks for all your help

If you have it rooted, did you ever perform a Nandroid backup ?
Do you have a non standard recovery installed?
EDIT: Sorry re-read last few post and come to conclusion that you probably don't.
sorry but doesnt rds lite 4.8 and the correct sbf file let u flash back to stock?
If your phone is rooted then you have changed your kernal.It might be a fault with the kernal.I had a similar thing happen in an SGS.It was rooted and when i flashed the kernal againh via CWM it also got stuck on the same as you.The only way to solve it was boot to download mode and flash via odin again.

Installed Cyanogenmod 7.2 RC --> Kernel Panic...wtf are my options?

As the thread title states...I was on 7.1 and downloaded/updated it to 7.2 Now the phone doesn't boot up and all I get is the Kernel Panic Upload Mode.
Anyway I can fix this? And if so, is there a way of doing it without completely formatting my phone and losing all my apps?
Oh and if it makes any difference I had to install that Siyah Kernel or whatever it was called to get out of the bootloop issue that I had with CM7.1. I'm thinking that that may be causing the problem....? But then again what do I know
wipe cache only.

How? I've been trying [Power+Volume Up+Home] and it hasn't been doing anything. Can I do it through download mode somehow?
Had this problem when i flashed Lite'ning rom. Had to go into download and flash stock with odin. Took me a few tries to actually get the rom to work. As far as I know, that'd be your only option, seeing as recovery doesn't work for you.
take a deep breath and read, there is a very small chance of bricking your phone just so you know. Flash back original with Odin and start everything again
thanks for the replies...looks like i'm gonna flash the stock firmware back and see what i can do about getting to CM7.2 to work. hopefully flashing stock firmware is enough. I can't imagine how this would completely brick my phone and render it unusable.
As an aside...wtf is the point of this "recovery mode" when the thing doesn't even work half the time?
Anywho...downloading the stock .exe file now from here: http://devsrom4android.blogspot.ca/2011/10/samsung-galaxy-s2-firmwares-bell-canada.html[/url
Ok so I flashed the stock rom and now I'm in Android system recovery: Should I just reboot system now or do I wipe data/factory reset or wipe cache partition??

If you flashed stock, you should be fine just rebooting.
Its stuck on the boot screen. I tried just rebooting, then wiping/factory reset, then both wipes...reinstalled stock a few times and nothing worked each time. I'm suck on the Samsung Galaxy SII GT-I9100 screen
:-\...when I go into recovery, I get a ton of red messages/errors
I'm gonna try somethig other than stock firmware see if that helps.
edit Ok so I rooted the phone and it got past the first boot screen and now appears to be stuck on the "animated S" boot screen...progress!!

Ok everything back to somewhat normal. Stock ROM didn't work but 2.3.6 did, so I'm on that. Now do I wanna go back to CM is the question...
Either way, thanks again for all the replies and helping me out with this. Greatly appreciated!

[Q] [SGS3]Stuck at Samgun Logo. All options have been expended, Desperately need help

Okay, So.. As the title says, i have googled for DAYS, Tried every damn thing i could get my hands on..
Now.
So far, im able to get into download mode, and also into recovery mode, I've tried doing a factory reset, and then flashing a stock rom, and i've tried every concevable method of fixing this damned phone, Its driving me crazy, I flash a new rom with odin, phone reboots, (adds to count) and is STILL stuck at that ****ty flashing samsung logo..
I'd really appreciate ANY help i can get, And i AM a noob at this, So i dont FULLY understand EVERY detail of this, But i've read around enough to know a few things.
My SGS3 has been out of commision for longer than i've actually used it.. So.. Yeah, Getting quite desperate!
Please let me know if there are any particular details yyou need!
Hi,
Your problem is EFS.IMG
Please clear it. Use Odin3 for that.
Boot into recovery and wipe data/factory reset, after you've flashed your ROM.
I had your problem some weeks ago,I finally managed to get arround this after I deleted the dalvik cache and flashed stock rom trough odin,and worked like a charm :good:
try this first before thinking of efs errors!

Thank so damn much for the help so far guys, i really appreciate it!
Cam't really help you with the EFS, but:
-bootloops are often fixed by installing rom then wiping data+cache from recovery as others said
-the dalvik cache can be wiped in the recovery, you can find "wipe dalvik cache" under the advanced submenu

Im in recovery mode right now (Vol UP+ Home + Power)? And i dont see an 'Advanced' menu option;
Options i DO have: reboot system now; apply update from ADB; apply update from external storage; wipe data/factory reset; wipe cache parition;
apply update from cache..
Any ideas?
These options are only available in a custom recovery.
Just try wipe --> flash stock room --> wipe

i just want to clarify... when you say 'flash STOCK rom' Do you mean i need to get a rom for a SGS3 VAU (Vodafone Asutralia) and flash that (go to odin, put it in PDA, etc)
and if THAT is the case.. Where would i get said rom, Because i've downloaded it from sammy firmware 4 times, each time it finishes the download without a hitch, when i go to extract the zip to get the needed files, it says its corrupted or some such BS..
Go to Sam mobile and download the firmware mate.
You will end up with a tar md5 file you flash using PDA section of Odin.
Good luck!

Kies is by far the easiest and safest way to factory reset. I have had to use it about 3 times in the past 6 months because I have flashed something I shouldn't have. Plus Kies now has a lite mode that is quicker at flashing your phone back to stock firmware.

Thanks everyone!

I9300 looping at samsung logo/unable to go into recovery mode

Hi guys,
I've really tried looking and I really cannot find a fix, thus this has forced me to come out of lurking and posting a thread to seek for help.
I wanted to flash back to a stock rom from my cyanogenmod10 to claim warranty for a broken digitalizer (touch screen completely not working), so my mistake was to flash via odin without wiping cache memory/factory reset and I forgot to use triangle away. (thought that i should have done that when I'm on stock rom)
so now my phone is unable to boot into home, it is stuck at the samsung logo, I can go into download mode but i have no way to get into recovery. (Holding the up vol + home + power just resets kinda restarts the phone)
Also, it seems like no matter how long I charge the phone, the battery level won't go above 10% on the standby mode charging screen.)
Anyone help ?
End of the day I really just need to get the flash counter back to zero without using the in-phone app to claim for warranty.
reflash the stock rom. if you do everything correctly, you would be able to access recovery

I've done that at least 3 times... using odin3 v3.07 flashed with I9300XXEMA2_I9300OLBEMA1_I9300DXELK1_HOME.tar.md5 selected only F.reset and auto restart, flashed using PDA.
The Odin tells me that flashing was a success but I'm still stuck, the last time i had this problem i settled it via clearing cache, but this time i cannot go into recovery mode anymore.

Try removing the battery.
Put back and go to recovery mode.
Then wipe data / factory reset.
Reboot.
Should work after that

Main concerns,
1) Reset Flash counter with computer.
2) Wipe Cache/factory reset function without going into recovery mode.
Take out battery, put it back in, press the three button Recovery combo and let go when you see the Samsung SIII screen. If you keep it pressed, it'll loop.
Do a factory reset then restart the phone.
Connect a mouse through an OTG cable and install TriangleAway to reset the counter.
Boot into recovery and factory reset. Should do the trick.
Good luck!
