[Q] Black screen after SAMSUNG logo!! - Galaxy S II Q&A, Help & Troubleshooting

Hey all
So I flashed Miui and got stuck in this black screen after samsung's logo!!!
My device is brand new just bought it yesterday which gets me worried
I just looked up the forum for answers and found that I should just flash a CF-ROOT. the problem is I DON'T know what version to flash as I'm on Miui I mean it didn't load up but I can see how it said "ROM WAS SUCCESSFULLY INSTALLED" and then nothing but black screen after reboot, what do I do?? I'll be thankful (

Either try a factory reset from recovery, assuming you can do that from MIUI recovery. I've never used it so can't be sure. Failing that, flash a stock ROM using Odin.

CF Root works for stock kernels.
As you're on custom right now do what hopper suggested above.
Then take a long breath and enjoy your device back.

[q] Phone keeps booting to "samsung galaxy sII" screen, and reboots? Help?

Hi okay so my phone keeps booting to the samsung galaxy s2 screen (the black one in the start)..and then it just shuts off and then goes on again...
I just flashed a new rom. This has happened to me with some other roms too and i thought it was cuz of the rom but this is happening with mulitple roms.
before flash i wiped data/cache, wiped davlik cache
I don't know what hte problem is, but it just keeps looping to the starting black screen..
Please help me flash the batista ics rom!
Do a wipe AFTER you flash the ROM, not before. Good luck.

Alternatively to any other suggestions, see the thread that is stickied near the very top of the Q&A section called "[READ THIS] Got a Boot Loop? Don't post a New Thread!".
yeah thanks,
not really useful though
can't get into recovery.
I can go into download mode but not recovery.
While i can flash another rom, I really want to flash the batista rom but i keep getting this problem. Is there something else that may be wrong thats not allowing me to install the rom on the phone?
No idea. And frankly, if you want to fix your phone, it's not important right now.
If you can only get into download mode & not recovery, the only way you're fixing this is with an Odin flash. You need to go back to stock, then try a fresh/clean install of whatever rom you were trying to install.

[Q] Can't change kernel?

I've been flashing roms a while now but have not encountered this problem. I can only flash roms with odin because i am not rooted, and i cannot root my phone. I am stuck on XWLPD kernel, no matter what kernel i install it never changes, why's that? Whichever ics rom i install the kernel never changes and stays XWLPD. I tried to root that so i could install a custom rom but then i get the yellow triangle and reboot and no superuser, no cmw manager and no root permissions, and kernel remains the same. I cannot downgrade to GB either as it just gets black screen after odin download mode and stays hot. I've searched through these forums for all sorts of solutions but to no avail, thus making this thread. Any help would be appreciated.
Could you state what you exactly did to change the kernel? And also you should have posted on the Q and A section

My bad. I should have. I came off from the Vk rom when everything was fine, and i decided to go back to a non custom rom so i used odin to install one of the released 4.0.3 roms which had the XWLPD kernel. After that, i couldn't root anymore, ater installing the cf root for the respective kernel i see the yellow triangle like all's well but when the phone boots up it isn't rooted. So then i tried installing another official rom XWLPF, installs and works fine, but kernel remains XWLPD, and it's like that for any other rom now. Going back to GB just shows black screen after the samsung sign.
Basically, i just can't install cf root anymore. Or change kernel.
After installing cf-root. Have you tried going to recovery and flash another custom kernel like siyah?

In doubt you could always flash back the recovery image from cyanogenmod wiki, and flash cm7 after. That way you're sure to get a fresh start and everything should work fine after!
It had a problem with my phone and this was the easiest way out.
Good luck

Thank you
Thanks guys. I managed to find a work around this rather unusual problem. I installed cmw from external storage, along with root, and changed rom from there. I couldn't change kernel, but atleast i changed roms. So i can live with that. Again, thanks.

Bricked, flashing stock rom doesn't work

Hey guys, I'm hoping someone can help me out. I've tried searching the forums and using different methods to recover it, but none have worked so far.
SO I flashed the ICS Domination theme over Diet ICS rom, stuff was continuously force closing, so I factory wiped with the intention of re-flashing just the rom... after a reset the phone was stuck on the samsung boot screen.
I've tried using Odin to load the stock Rogers rom, it says it worked, but trying to boot the phone up its stuck on the samsung boot screen.
Am I missing something? Is there anything you guys can suggest I try??
EDIT: Oops, wrong forum, meant to put this in the AT&T forum
Snap my phone is stuck on samsung screen for awhile now, it's not doing anything at all
Wipe everything in recovery and flash a rom from either recovery or odin..

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! ^_^

[Q] Possible brick after CWM recovery update.

Here goes, hopefully someone can help!
Ive installed a fair few roms on my phone and never had any issue, maybe this explains the complacency.
After updating to CWM recovery -6.0.4.7 I get stuck on my bootscreen, only seeing "Samsung galaxy I9100P" , ive been putting I9100 roms on it and losing NFC functionality for a while.
I went to update to the newest CM-11 nightly and read I needed to update CWM-recovery first. So did that, rebooted phone as instructed after installing new CWMr and nothing. Just stuck on I9100 screen.
No way to get into recovery mode, the only bright side I have found is I can boot into ODIN download mode. So what would be my next steps anyone?
Flash stock rom. or flash a kernel to get a working recovery bk with odin.

From a dig through the forums it sounds like NAND rw corruption?
I wouldn't be calling it that just yet. Unless you'd like to pay for a motherboard replacement ? Most of these are recoverable.
Used ODIN and flashed a new kernel, still on the boot screen, except now I have the yellow exclamation mark. Now to, Firmware upgrade encountered an issue. Please select recovery mode in Kies and try again.. this day is not going well..
Fingers crossed, flashed 3 or 4 kernels before one worked and allowed me into recovery mode. Trying to restore back to my backup from this morning. Heres hoping! :good:
Worked perfectly, the first thing I did was retry the initial task which was what got me stuck, currently waiting on CM-11's initial boot up after a successful install Thanks for the calming responses!
