Help with broken sgs2(noob) - Galaxy S II Q&A, Help & Troubleshooting

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?

The problem is moving from ICS to GB.
Just flash back CM9, assuming you can enter Recovery...

He can't enter to reco. Only DL mode.
So, you need to flash back stock ICS, root, full wipe and again flash GB.

[Q] Phone wont boot past Samsung logo

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.

[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! Tried to root after offical ics, now hanging at samsung loading screen.

My phone wont boot now.
It stays stuck at the 2nd Samsung during the boot up.
What happen was I updated today to offical ICS from my rooted gingerbread.
I updated via kias today to get official ICS, got it working and I noticed I didn't have cwm install anymore, so I followed this http://forum.xda-developers.com/showthread.php?t=1504218
It is pass it did it reboot thing, and never got past the 2nd "samsung" loading screen.
Anyone know how to get my phone booting again?
Flash the latest ICS kernel
I am not sure how to do that without cwm.
Before I updated to ICS when I press power + up down, it booted into CWM. Now when I do that I boots into Android System Recovery <3e>
EDIT: Good news.
Got CWM through installed though odin and then I restored to my gingerbread backup I made earlier.
Flash your roms via clockwork recovery mod from now on.
Drop the ROM .zip on sd card and then enter recovery. Wipe everything three times each then flash a uclf6 based ROM. Never touch Odin or kies again. Be happy. Ice cream sandwich is way better than ginger bread

Had the same exact problem. I "believe" the problem was that the CWM I flashed was perhaps incompatible with the official ICS?
I used Odin to flash cwm 5.5.0.4 as suggested and the fone was shut down with the hanging Samsung screen as you mentioned. I used the DL screen with Odin to the 600mb Team Objection ROM, which at least got me up and running again. I found out that CWM did in fact flash once the ROM was compatible with it. Updated CWM, then to finally get full stability, I had to do a factory reset after clearing both caches, then install the CM9 official.
Sent from my SAMSUNG-SGH-I717 using xda app-developers app
Update: I installed official ICS again last night, looks like I lost my root and CWM.
I don't want to mess anything up again, so could you tell me exactly what CWM file you used to flash so it doesn't hang at samsung again?
I was having the same problems but I think I was doing it wrong. How are you flashing the root files? I upgraded from Kies, then used Odin to flash cwm touch (5.5.0.4 I think), make sure to let the reboot and that it's actually turned on and you can see your homescreen. Once you do that, THEN flash the superuser 3.0.7 in cwm. Let the phone reboot properly and it should be okay.
I was doing the same without the reboots and that's what caused me to hang at the logo, but after the above it worked well. Give it a try. For anyone who needs to flash the T-Mobile radios also let the phone reboot and then flash it because I was having issues with that which was fixed by letting the phone reboot.
Make nandroids at every step in case it does hang so you can just restore and try again instead of flashing everything all over again.

I've also tried rooting my AT&T Galaxy Note I717 which had recently upgraded to ICS via AT&T/Kies and my phone is stuck at the Samsung boot screen. While I'm no expert with rooting phones, I had no problem rooting it when it had GB installed so I figured I wouldn't have any problems rooting it again. Is flashing the ICS kernel the best way to fix this? Where do I get the ICS kernel from and how do I flash it?
Details: After my phone upgraded to ICS 4.0.4 kernel 3.0.8 (IMM76D.UCLF6), I followed some instructions to root it using Odin3-v1.85 and PDA->pda.tar. Other instructions used cwm-touch-i717-120414.tar.md5 and odin_n1717_cwm_recovery_b4.tar and I tried those but to no avail. So I have CWM v5.5.0.4 installed but I don't know what to do next.
Any help is greatly appreciated. Thanks!

Update: I restored my phone back to a non-rooted working Android 4.0.4 by downloading the stock ROM for my phone (I717UCLF6_I717ATTLF6_I717UCLF6_HOME.tar.md5) and uploading it using Odin3-v1.85/PDA. I didn't even lose any of my settings or data. Now I need to figure out how to successfully root it. But at least I'm not worried about getting stuck on the Samsung screen anymore.
Open odin , PDA cwm file, Droid in dl mode, plug in start unplug, reboot, go to cwm recovery mode and backup onto sd card.
Im learning more, as i soft bricked mine last time

You realize the reason you were stuck was because you flashed a GB kernel onto an ICS system? It would never boot. As the second post suggested... all you had to do was flash an ICS kernel to get it to boot.

so correct...you nailed it...so many are trying to root with gb kernal....
I hope they go to the page I made and follow the green arrowed how to root ics...it is very super simple process to root the official ics...but ....
This happened to me after misreading a comment.
If you put your phone into download mode, plug it in, run kies, and do an emergency firmware recovery. You'll need the serial number. My phone is stock ICS again. Works fine.

so cwm 5.5.0.4 touch is a GB kernel? Because that's all I flashed after the KIES update to ICS and I got the hanging Samsung logo.
I believe some people are trying to get ICS rooted with this cwm and are getting stuck. Of course there are ways out of it, but it'll help the learning process if we can find the problem.

you need to read read read read and PLEASE read
Because CMW is not a kernel
Its a recovery
People wouldn't have these issues if they read.
Please refer to the stickies before you really damage your phone.

The OP had posted that he flashed Da_g's GB kernel trying to get root...your issue if flashing CWM may be different. Hopefully you use the steps outlined by bigjoe in his post.

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.
