[Q] Phone wont boot past Samsung logo - Galaxy S II Q&A, Help & Troubleshooting

Greetings All,
So I was using DarkyRom at one point and then I decided to go to MIUI. Tried it for awhile, did not enjoy it so I wanted to go back to Darky. So I went to flash the kernel and when the phone rebooted it went past the logo screen and straight into a pitch black screen. So I left it for ~ 10 minutes and nothing happened. stayed at the black screen. So I pulled the battery out and now the only part of the phone I can access is the Download mode (had to pull the battery out to get out of that as well, would not switch off). So how do I fix this? Is it a boot loop? I have Odin but this PC has never had KIES or the Samsung drivers installed on it so I am not sure if that will cause a problem. Also I was using a KI3 build, can I flash stock KH3 (from this thread: http://forum.xda-developers.com/showthread.php?t=1075278) with Odin and will the phone still work?
Any assistance (or reassurance that its fixable) would be greatly appreciated.

Probably fixable flash a stock rom from the stock rom thread as first step.

Using Odin? And can the stock be a KH3 ROM?
*edit*
Found this thread: http://forum.xda-developers.com/showthread.php?t=1348374&highlight=black+screen+after+boot+logo Would this work for me? Even though I was using a MIUI ROM?

Agreed, try wiping cache/data and flash stock ROM with bootloader.

Cant access Recovery Mode to wipe cache/data, only download mode.

[Q] help kernel panic upload mode only

Just flashed a custom ROM like normal did 3 wipe data, cache and dalvic then all of a sudden I got this phone message above any help would be much appreciated
Kernel panics occur when the system incur a fatal error and has no possibility to "live" any more. windows blue screen when it is called
Kernel panics arise from two reasons:
First (must have been an app with root rights) faulty memory accesses
Second defective hardware
=> just reflash and look whats happening
Reflash rom .
Search XDA kernel panic
Most KPs on here have not been hardware problems many are beta ICS rom problems .

Kernel panic upload mode
I was flashing custom ROMS from couple of months and did dozens of times.
But when I was flashing resurrection ROM an updated version, it completed but when I rebooted it was stuck in the kernel panic upload mode after the boot screen(galaxy s2). It was not going to clockworkmod recovery too. Then using the odin I tried to flash the stock ROM as well as custom ones. But it will finish, will stuck in the boot screen. Then flashed recovery using Odin and tried to flash custom roms. Couple of ROMS worked but most of them failed and stuck in the boot screen. I could able to restore the stock version which I saved previously.
But I cant try most of the ROMs now. CM9 didnt work.. But MIUI worked.
Can anyone help me.???
Ouch
Ok this is what's up,
I flashed a 4.0.4 Sammy ROM after wiping everything in a speedmod CWM recovery and my previous ROM was also a 4.0.4
Now for some lame reason,phone's gone into this stupid kernel panic upload mode. Maybe my new ROM was f****d up.
I flashed that new ROM and siyah 4.1.1 and the phone gets stuck on that gokhanmoral symbol.I try going to recovery mode ,it goes into kernel panic.I try download mode, still goes into kernel panic.
I've ordered a USB jig as a last resort.
Anyway to fix this before the jig comes coz it might take 3 days and I cannot live without my phone for that long

flashed skyrocket stock.tar by mistake!!!!

Like the title said, and now even thoug it goes into download mode, it doesn't go past the att logo when tried to flash the att stock .tar' or if I try and flash any other rom (rooted), it doesnt go past "android" animation. It goes black and that's it. I'm afraid I damaged something really bad, and won't be able to fix it. Any thoughts?
If you can go into download mode, just flash stock Note rom through Odin. I figure that's how you flashed skyrocket.tar.

Like I said, already tried that, my flash counter keeps increasing (30+), but same results. Maybe messed up the bootloader, or something?
which skyrocket tar did you flash? Make sure you get the right version
Try a full restore see here.

Can you get into CWM mode?
If you can boot to Samsung logo the bootloader should be fine. I would re download the stock note tar and then Odin. I had a bad tar and had the same issue but I didn't flash a tart from another device. Flash cwm in Odin to see if you can boot into cwm first.

Thanx all for your replies, I found my answer in other thread. My problem was that after flashed the stock.tar, when I tried to go to recovery,the phone just vibrated and vibrated, SO I followed the instructions of that member,and voila! Went into recovery, factory data reset and everything was fine. Thanx to ya'll.

Help with broken sgs2(noob)

Recently i had been trying different roms using ROM manager. This morning i was using nightly from CM9 and from recovery i tried to install CM7
I dont remember having done any wipes as i thought it wasnt necessary no errors ocured but when i tried to reboot my phone it gets loop on the very first screen that is like samsung galaxy s2 and this yellow triangle. I cant acces recovery neither download mode, i dont know how to undo this but im gettin even scared of loosing my phone. Please help!
Can your phone boot into Samsung logo?
I believe Cm9 is an ICS based rom and CM7 is a GB based rom so they are quite different and probably require a full wipe before moving from one to another. Are you able to enter recover or download mode?
Sent from my GT-I9100 using xda app-developers app
The problem is moving from ICS to GB.
Just flash back CM9, assuming you can enter Recovery...
Sent from my GT-I9100 using xda app-developers app
He can't enter to reco. Only DL mode.
So, you need to flash back stock ICS, root, full wipe and again flash GB.

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

some quick help needed

i recently installed via odin the stock jellybean release rom on my phone along with cfroot and simunlocker.
i have found the stock jellybean rom to have a few too many bugs for my liking and want to go back to stock ics.
I have downloaded the stock ics rom latest release and tried to flash it again using odin in the pda box, it all seems to go fine but then the phone only seems to reboot as far as the samsung logo then stops.
What have i done wrong and how do i fix it please (or should i just be waiting longer for it to boot from the samsung logo?)
thanks
Try boot into recovery and factory reset.
