The phone won't boot. - Galaxy S II Q&A, Help & Troubleshooting

I tried to install CWM using ODIN, and everything seemed to go well, but when I turned the phone up, it will show the model's name and a yellow warning sign, and then go black forever.
I thought it was because the CWM installation deleted the kernel (It was written somewhere in the guide) so I flashed a new kernel with ODIN, but the problem presists.
I tired to wipe it through recovery, and nothing. any help?

Device stuck at boot screen after flashing VillainROM

Hi all,
Today I wiped all data and cache from my device and installed VillainROM from CWM Recovery Manager. Install looked fine it said that it finished, so I went to reboot.
The device was stuck on the Samsung Galaxy S II logo with the yellow triangle (!) for around 10 minutes. I then turned it off cause I realized it wasn't going to boot.
Anyone have any idea why this happened? I restored a backup of my previous ROM and my phone booted up real fast and it was fine.
Could just be a bad download?

Try flash it again before it boots. IE: Flash from zip, then go back and falsh from zip again.
I've had to do that with CM...
OK will try that, cause the same thing happened to me when I installed Cyanogenmod straight from Rom Manager. Thx
Update: No go, I also made sure Deluxe Settings was uninstalled before I went into recovery. It's stuck at the boot screen.
However, upgrading my previous ROM (WanamLite v4.0) to WanamLite 5.2 worked fine and the device booted. It was exactly the same procedure in recovery mode but a different ZIP file.
Will try another ROM like LiteningRom and see if anything changes. I don't think it's a CRC error because I open up the files before I copy to the device to see if WinRAR pops any CRC errors.
I'd start on the thread a few up from yours.... the one that mentions if you have a boot loop
Sorry, I didn't realize it was a boot loop because it wasn't actually looping, just stuck on the image. Is that considered a boot loop?

[Q] A bit of help please

Hi I have tried flashing my S2 but have run into an issue.
So i installed clockworkmod recovery 4.0.1.4 with the intention of installing cyanogen mod.
I then rooted the device using S2 root which said it was successful.
This was confirmed when i then installed and rom manager premium.
I downloaded Cyan from within rom manager and proceeded to install.
I selected to wipe data and dalivk.
The phone rebooted but hung for a long time on the white 3d triangle with an orange exclamation mark.
It then went into the clockworkmod recovery and I rebooted presuming everything was done.
Then my phone started as normal but went into the original rom but there was no app's, icons ect. I rebooted and app's icons were back.
So I rebooted into recovery mode again and tried to update from sdcard. no difference. So i read that wiping data/factory reset might help but now all i get is the boot loop between my carrier startup and the standard S2 startup.
I can still get into recovery and download mode but when i enter download mode I cannot see the phone in odin.
I have also tried putting the update.zip on my sd card manually from a PC download and use recovery mode to install it but thats not installing it either.
Any ideas or is my phone fubar?

Hi thanks for the reply, i wish i had found that thread before attempting this.
I have managed to get odin seeing the phone now so its looking good.
problem i have is i need these:
XWKJ1:
Firmware info: PDA: XWKJ1| Phone: XXKI4 CSC:O2UKJ1
XWKJ1 Stock Kernel:
Password is: [email protected]
but multiupload was part of megaupload i believe so everything is gone.
Do you know where else i can find these.
Not sure why you'd want it, but

Thanks its just a learning curve, i will put cyan on again properly but want to learn as i go on how to do it right first time.

CAn't revocer I9100m

Hello
Here is short story:
I rooted i9100m, everything was fine (method entering recovery, open cwm and install busybox)
So I wanted to install cm9 and took rc2 for sgs2, boot into recovery, 1st I did wipe factory reset (took very long) and clicked on reboot phone after reseting, instead of install from sd... (no big deal I was thinking). Phone could not move from boot screen even after taking out battery and restarting.
After that we tried CM9 from cwm, CM9 with odin( version for odin of cm9). always the same, stuck in boot. I found this soft brick unbrick thread on this forum and tried flashing stock rom (bell canada) nothing....even tried stock ginger..same story. when I tried to wipe reset data I get kernel panic (after every flashing I tried to reset/wipe). Sometimes its "kernel panic" sometimes "E: /data could not be mounted or found" (something like that)
I still can enter download or recovery mode
I searched whole forum for solution but I couldn't find it
PS: there was a method with ODin using this pit and repartition but from provided download link was only stock rom nothing else.
please help

Reset Phone In Settings - Now Won't Boot

Hello,
I was going to sell my phone to a friend today. I was running CWM recovery and paranoid android ICS. Anyways, I simply went to settings --- > factory reset ---> checked "wipe sd card" and hit OK.
Now it won't boot. It'll go to the Galaxy S II screen and shutoff. It boot loops while trying to boot into recovery mode.
I can, however, get it into download mode. I was looking at guides on here on how to reset it and are confused as can be. Where can I download Heimdall (yes, I googled it, couldn't find the download on their site.)
I'm on Mac OS X, if that helps, however I can get windows if it'll make everything easier.
Thank you
Use the guide linked in my signature, for returning the phone to stock. Link for heimdall is in the guide.
First enter recovery if possible, and perform a wipe data/factory reset from within recovery. If successful, joy.
If not successful, then flash stock using Heimdall, or borrow a pc and use Odin.
Forgot what I said earlier...I hooked up my Windows 7 SSD and booted into Windows.
I flashed everything successfully in Odin (only flashed a PDA/Phone part, not bootloader or CSC.)
Now it's stuck looping "Rethink Possible" AT&T Logo. However, I can get into some form of android recover. I don't know what I can flash through it, though.
Any help?
Thank you

stuck in boot similar problem
I'm having trouble booting my phone. I rooted using Odin3 and siyah 3.4.2 it flashed i was no longer able to view video or the live picture of the camera. I was using another site galaxys2root.com as my guide and failed to be resolved in the forum there. In an attempt to resolve the issue I went into factory reset using power vol+ vol- and tried to wipe the system but it didnt reset competely still had the siyah running. I then attempted to use reset within setting and now i am stuck at the first boot screen "samsung galaxy sII GT-I9100". It will also show charging but only briefly then it goes black. I would just like to get back to stock ROM if possible. Please advise.

Bad choice going to galaxys2root.com. Now I have said it. Let see what we can do to get you back.
1st - if you can get into the recovery mode, go here and download AJ's Siyah kernel. Download your favorite ROM
2nd - Flash the ROM first, then Flash Siyah kernel through recovery. Reboot and you should be good to go.
Enjoy.

[Solved] Unable to boot into ROM and CWM recovery

I had to restart my phone for some reason and on restarting, the phone got stuck in a boot-loop ( Samsung galaxy S3 i9300 ) text logo. I thought I'd reboot into CWM (Philz touch) and wipe to make things better. But the phone won't boot into CWM either, it showed the soft navigation keys and rebooted again, and kept running in a bootloop of trying to get into the recovery and restarting again.
So I tried to ODIN the recovery just to refresh if something is broken. It didnt work. Odin was success but the boot into recovery wasn't. I tried several times but no luck.
Then I flashed TWRP using ODIN, and voilah! i could boot into TWRP . I flashed CWM using TWRP and voilah again, i could reboot into CWM again . After thatI had to flash the ROM again though.
I do not know why it happened, but I thought I'd share the details just in case someone tries to google it.

You have to remember what exactly you have done before rebooting. Some times it happened with me mainly changing boot screen, battery screen etc.
