[Q] Galaxy sII stuck on boot screen and cant wipe - Galaxy S II Q&A, Help & Troubleshooting

I was very happy with my CM9, than I realize that I never used te stock rom, thinking about the upgrade to GSIII I wanted to test the stock. Grab the files of original brazilian rom of SGII ICS unbranded and odin...
every thing was almost normal, but I wanted to go back to the cm9, used the rom manager and.. my phone was stucked in boot animation. Used odin again to reflash the stock rom, stucked in S animation.
What do I do?? Remembering that I open the custom recovery and was unable to wipe data/factory reset - the phone freezes and reboots
Please, I need to fix my phone!

Hi mate have you not tried flashing CM9 with Odin for a clean install rather than using recovery ?

I tryed the cm9 odin files and didn´t work.. After 3h searching I found "probable fix to lq5 brick" and it works.. my sgs2 is now almost normal... i have black screens of death (or sleep of death SOD or whatever name you want to call) and random freezes, reeboots and FCs....
any sugestions?

Have you undervolted your device? If you have, return them to the stock values.
Or
Try a different kernel. Like dark knight v1.9.1

Try to go back to Stock with a pit and repartition.
Then flash a custom Kernel and then try CM9 again...
If it stucks somewhere in Recovery/Installation or in Bootloop go in Recovery again and install CM9 again!

[q] stuck at startup screen

I was trying out CM7 nightlies but the bugs were overwhelming, and when I tried to restore my previous ROM through Clockworkmod it couldn't find the boot image. I rebooted and have been stuck on the Vibrant/Samsung startup screen ever since. Can anyone help?
Ur just gonna have to pull the battery and odin back to stock. Then root and flash cm 7 but dont forget to wipe

I agree. What was the ROM you tried to restore? was it a 2.3 gingerbread ROM as well as CM7? or was it a 2.2 ROM that you tried to restore while still running 2.3 CM7?

CM uses a different file system from other ROMs (MTD/yaffs2) which means your old ROM's kernel won' t be able to read the file systems on the phone. You need to Odin back to stock with a re-partition, re-root, re-install clockwork and re-flash.
There a sticky on how to use Odin, and how to get into download mode here:

no harm no foul!
as soon as i saw the word 'kernel' here i knew what i'd done. i did try restoring back to gingerclone 2.2 while still running cm7. wah wah. but no harm, it was my girlfriend's phone and she's already back from tmo with a brand new galaxy s 4g. thanks for the replies fellas

[Q] sgs2 wont boot, just black screen

Flashed CM9 to experiment with it and see how it ran, prior to doing so made a backup of current setup (unnamed 2.2.1 w/ siyah kernel). After flashing to CM9 and playing around a bit i was going to revert back to my original setup. Tried flashing back and now I am unable to even get to CWM Recovery, or Download Mode. It will boot to the SGS2 screen and then just go black no matter what I do. It is still recognized in Odin so I was thinking I'm going to have to revert back to stock and just flash it back afterwards. Any ideas before I proceed?

Flash back to stock. Strange - you say you can't get into download mode, but Odin recognizes it?
Ok, finally got into DL mode and flashed a stock kernel from Entropy's post. Now i'm faced with it booting to the ATT splash screen and it just loops that screen infinitely. I'm still unable to access recovery mode to wipe data/cache or anything like that. This is becoming frustrating and I'm not quite able to wrap my head around why after flashing stock that I'm unable to boot into the phone beyond the splash screen. Am I using the wrong stock fw or something? Here's the link to the one i used.
http://forum.xda-developers.com/showthread.php?t=1286432
From my experience it's the wrong SPL/radio combo.
No matter what I do, I'm stuck up to that point.....I've tried a few different stock flash packages through Odin to no avail, same result every time. I know i'm probably doing something wrong or I'm missing something here, its not bricked I do know that so its not like i'm dead in the water here. Any ideas would be better than where I'm at currently.

There is no SPL on the GSII, and a bad radio will only screw up calls/cell data.
To the OP - exactly how did you flash CM9? CWM or some kanged-up Odin build?
Through CWM, everything worked fine but when I was using CM9 my back button and serach button weren't working, probably erroneous to this situation. this is just messing me all up that I'm able to boot up til the splash and then it just loops it over and over, its making me think that the FW is having issues loading or something.
Problem solved finally. Something must have changed after this last flash attempt because now I was able to get into CWM of all things and recover my old backups. Nice little adventure that was. Thanks guys for the help!

Brick after Rom Manager Reboot?

Hi
I searched and only found similar cases with other phones and no solution.
I was on stock 4.0.3 with CWM, rooted and siyah kernel and tried to upgrade to CM9
with Rom manager
i dled cm9 with gapps and let ROM Manager do the backup, wipe and reboot to recovery
but then i just saw the first GT 9100i boot screen with the triangle and after that
the screen stayed black.
i noticed in a darker area that the screen blinked everey few seconds, so i guess its trying to reboot all the time. some kind of bootloop?
i cant access the cwm, nor boot normaly.
just the download mode is working
so i tried to flash a stock FW from intratechs thread via odin
but... FAIL
help would be much appreciated right know :crying:
thank you
Mmm I've had issues with rom manager before but never this severe. All I can suggest is what I would do which is to fash stock firmware from samfirmware via PDA section in odin. If this doesn't work I think there is a sticky thread which is dedicated to situations like this. It requires flashing a firmware via odin again but all partitions are used so it will wipe your device. All the best.

Can you still get into Download Mode?
EDIT:
Try manually wiping data, cache and dalvik cache.
Try to go into recovery. Hold down volumen up, home key, and power on, at once hold them down ontil you reach recovery.

I had that problem too-a black screen with a flash down the rh side of the screen every few seconds.
I managed a repair via odin after a couple of attempts.

Flash a stock kernel then wipe everything the recovery it comes with. Also make your flashing roms for your 9100i model.

I have the very same problem as you.
I can enter download mode but can't enter recovery mode.
I can flash any rom I can find but all of them have no use.
Still can't boot nor recovery.
Have you fixed the problem just by reflashing stock rom?

Yes, that's our fault that haven't read enough before installing a software.
But is there any way to revive our phone?

the only way to revive ur phone, is to flash a stock ICS 4.0.3 firmware thro 'ODIN' and have a clean boot of ur phone
and never use 'Rom Manager' in the future

Help...I think my YGP got bricked -_-

I was reflashing back to stock firmware gingerbread 2.3.6 from eryigits due to its massive slowdown from its initial install. But then after flashing the stock firmware it boot looped so i thought maybe there was something wrong with the partitions and loaded what I got from another thread. But then the progress bar in Odin wasn't moving at all so I terminated odin and opened another instance similarly it didn't progressed. I plugged off my ygp and rebooted only meet a cellphone logo and a computer logo with an exclamation mark unpleasantly called black screen of death. Is this what they call a brick? Should I follow the guide on hardbrick recovery ie http://forum.xda-developers.com/showthread.php?t=1496360?
Yeah use the unbrickable reserector

No, this screen is the forced download mode also called lucky brick. So while you are on this screen the player should be detected as it is in download mode. So you should be able to flash your rom.
Just flash the rom in odin again see post above me
if it bootloops again format the device in recovery mode
There is a way to fix this.
I was flashing STOCK GB 2.3.6, because i didn't like Erygit's rom, and i got the bootloop too.
The bootloop was caused by the fact i didnt do a Factory data reset, and when i did it, i rebooted from Recovery and the Stock ROM booted.
Just do a factory reset from recovery, it should work.
Thanks for the swift replies and sorry for my late reply as well! Thanks alot for your recommendations. I haven't been able to touch my ygp for awhile due to school. But I'll surely try out everything suggested. Btw I kind of already reflashed the stock gb rom it bootlooped after so I pretty much didn't have a cwm recovery. But I'll try flashing it in a while! Thanks again! ^_^

Phone booting in loop and cannot unbrick

Hi !
I am using a Samsung Ace S5830i since 2 years now with a custom ROM : Ace-i-Sure 12.0, all worked properly.
Yesterday I installed an app, I do not remember which one but I think it was a game, then my phone rebooted and looped on the boot animation.
I am used to unbrick my phone and change ROM so it did not scared me.
I tried to flash the stock ROM I used to flash everytime my phone has been bricked. Flashing went OK but my phone kept looping.
I tried to wipe data/factory reset but nothing changes.
I tried with another stock ROM found here and nothing changes either.
Do you know what might causes this problem ?

I tried flashing your firmware amolgosavi and followed exactly the steps of your tutorial brijeshep but nothing changes...
Can my phone be hard-bricked ?

and no it is not hard-bricked...
Hit thanks if I helped
I tried all the solutions you gave me but nothing works, I do not understand...
I might buy a new phone, but I ain't got much monyer, I can spend maybe 100€ or 200€ maximum
Does your phone enters into download mode and detected in odin?
What's the status during flashing ?
Then try the flashing methods on another pc.
