[Q] Keeps on rebooting - Galaxy S II Q&A, Help & Troubleshooting

My I9100 keeps rebooting. Things I did..
1. I had stock rom I9100XWLS8 upgraded from ICS 4.0.3.
2. Installed Siyah kernel using Siyah-s2-v6.0b4.tar and rooted the phone.
3. Power button menu and screen lock was not working, for which I got info from other thread and tried - it didn't work for me.
4. As advised, I booted into CWM Recovery and wiped data/factory reset and rebooted.
5. Once it got booted got menu and went into reboot cycle.
6. Flashed stock rom I9100XWLS8 using odin.
The rebooting cycle doesn't end. Any help/ suggestion ? Thanks in advance.

[Q] Stuck on a boot loop

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.

Give us more details on what you have done exactly before you flash the rom.
And details about which rom.
One solution would be to flash stock.
Go in download mode with 3 buttons combo(volume down-power and home button) open odin,put as pda the stock rom as a tar and hit start.
Note: Be sure kies tray agent is not running in the background you have to kill the process with task manager
I also have this issue, after using a CM9 rom then rolling back to stock rom I have downloaded the stock rom, not sure if its 100 match for my phone but its stuck at samsung logo its 1 day old, please help?
Thanks
get into download mode and try flash again.
Right, I can go back to custom rom, but stock rom wont boot, any suggestions?
please try to elaborate the exact steps that you have done to get to that situation.
if you are now flashing back to stock rom. try this, flash stock firmware using odin, once done dont reboot. straigth boot into recovery mode, and wipe data factory reset. then boot.
ive got the same problem. i installed cyanogenmod 10 on and it worked fine but couldnt get to wipe the internal sd card so still had stuff from past roms on. I thought if i flash back to stock then it would clear it all then i could reflash back to cyanogen 10.
i flashed the stock in odin and it wont go past the samsung logo. cant get into the recovery mode to wipe cache as it just resets back to boot screen and cant use the samsung toolkit as i cant get into usb debugging mode as cant get it to boot
any help really appreciated

I had this issue before. Phone is stuck at samsung logo. I reflashed stock lfb firmware and cf root. Cleared data/cache/dalvik. Then it worked fine.
If every recovery method fails then only resort is to visit service center, go there and act dumb and state phone went crazy and this happened out of no where.If they wont find out that you've f***ked it up then you will get mo-board replacement.
Flash stock LFB from samfirmware.com through Odin.
Then flash Siyahkernel (also through Odin)
Pull the battery for 5 minutes
Press and hold vol-up + home buton
Press power button until screen lights up
You should be in cwm now. Factoryreset your phone and it should startup again
If you don't want to loose your data, instead of factory reset you can try using adb shell and run e2fsck on the block device for /data
Corrupt ext-Partitions are usually the reason for a softbrick

I encountered the same problem. I almost fainted when I can't solve the problem. Finally I did. this is what I did:
1. download the Stock Rom (depends which country and carrier you are) Unzip the downloaded file and you should have .md5 file that you will later use.
2. download ODIN
3. Launch ODIN click on "PDA button" select the .md5 that you extracted (the file you downloaded and unzipped) and click start and wait until it finished (hopefully this will solve your problem but in my case ... the samsung logo still is stucked so continue with my next steps)
4. download the CF Root from
note: this will install the CWM or recovery mode for your phone that will give you several options ...
5. use ODIN again and click PDA button and select the CF Root that you have downloaded and click on start until it finished.
6. boot to Recovery mode by holding "volume up (yes volume up and not volume down)" and "power" and "home button" all at the same time until recovery mode reappears.
7. go to advanced and remove dalvik cache, do a wipe out or factory reset, wait for your phone to restart ... wait a minute or two and your phone is back to normal.

[Q] Won't boot, worked fine, then bootloop, now it freezes (using CM9 ICS Nightly)

Hi Friends,
Model Number - GT-P7510
I recently rooted and installed the CM9 ICS nightly rom using the noob video instructions (This included rooting with Odin, installing CMW recovery 4.0.0.4, then I flashed the ROM cm-9-20120624 Nightly and finally flashed GAPPS-ics).
I over clocked using the CM9 settings and everything worked perfectly for about a week, it was great. Then it just crashed while I was reading my email and began to bootloop. After reading for similar errors I rebooted to recovery and tried wiped the cache and dalvic cache, I wiped data and factory reset several times but nothing worked, always the same bootloop. I re flashed the same ROM and still nothing, after a while the boot screen would simply freeze instead of bootloop.
Then I connected to my PC, and did this to no avail. In fact it simply added to the problem by adding a yellow warning triangle while attempting to boot so I did the Oden thing again like the first time I rooted however I installed CMW version 5.5.0.4 instead thinking it might help but it hasn't.
One last point, when I attempt to wipe data/factory reset the tablet seems to freeze and attempt to reboot rather than say something like "success" as it would during a cache wipe. This maybe normal or it maybe the problem! who knows?
On that point, I would be very grateful if some of you could help get me to the point when my PC recognises the tablet so I can reflash a new ROM.
Thanks in advance,
Karl
I once got the same problem. The only thing that helped was to flash back the stock rom via Odin with the pit file. And don't forget to do a hard reset after flashing the rom. I'll just stick to the stock rom until the official update is getting released.

Questions go in the Q&A section
I think the best way is still to do factory reset, go back to the stock ROM first and try custom HC ROM until the official ICS is released.

Can't install CWM, need a little push

So obviously i didn't do enough research before i started playing with my phone, and i'm sorry if my question has been asked a hundred times but i have done alot of reasearch and i still can't get it to work.
I succesfully installed a custom rom some months ago (resurection i think) and i wasn't happy with it (some bugs). So i wantet to install FOXHOUND Revolver Ocelot but then weird things started to happen. It all ended with a boot loop but i got it back to normal thanks to the sticky (http://forum.xda-developers.com/showthread.php?t=1457458). Now i have tried to install various CWM.tar via Odin so i can flash FOXHOUND Revolver Ocelot (http://forum.xda-developers.com/showthread.php?t=1162715). But everytime i try to install CWM it just hangs at boot screen with the yellow triangle and doesn't go any further. If i press Vol up + home + lock the phone restarts to the same boot screen and it stays there. If i shut off the phone it reboots and hangs at the boot screen.
So my question is really, from the point i'm at now (fixed brick with the aforementioned sticky) what should i do? Install a different kernel? (suggestion?) ROM manager (which?), root and then flash FOXHOUND Revolver Ocelot?
This is the info from About phone after i have followed the sticky to unbrick phone, if its interesting:
Model Number: GT-I9100
Android version: 4.0.3
Baseband version: I9100XXLPH
Kernel version: 3.0.15-I9100XXLPH-CL118559 [email protected]#3
Build number: IML74K.XXLPH
Try flash kernel via Odin for example syiah its good kernel ans that should fix when u flash go to cwm vol up+home+pwr button and wipe delvik and fix permission and boot

Thanks for the help. I tried to flash the siyah kernel via Odin, and I got a pass and all seemed good. I reboot my phone, SGSII bootscreen, then siyah bootscreen, then black and nothing. Tried multiple times. Booted into recovery and wiped dalvik and fixed permissions. Same thing still. This also happened when i tried to flash the Dorimanx kernel yesterday.
Am I doing something wrong?

Thanks for the help guys, really appreciate it.

[Q] Failed root, failed restore. need help (warning idiot inside)

Purchased I9300 a couple of weeks back and decided to checkout the toolkit, make some changes (with the aim being better battery life)
downloaded and installed toolkit.
followed on screen instructions - 76d xxblg9
once rooted and busybox was alledgedly installed phone reboots to hang on samsung screen.
restoring flash lead to the samsung logo not even appearing.and repeated rebooting got me to the sim unlock page, to be told that android had stopped working and a complete hang.
downloaded GT-I9300_NEE_I9300XXALE8_I9300NEEALE3_I9300XXLE8.tar.md5 and odined in (closest stock flash i could find, being a nordic resident)
now hangs on samsung logo.
so my question is twofold
1 - which stock flash is it i need, or should i just get hyperlite?
2 - an anyone point me to another thread regarding stockflashin the i9300? (as my search skills have failed to find anything that helps after 2 hours)
sincere thanks

You could do a wipe in stock recovery but it will wipe your internal storage.
