[Q] GT-I9100 won't boot, yellow triangle. - Galaxy S II Q&A, Help & Troubleshooting

Hello.
I was flashing CWM through Odin, as it wasn't included in the root. The installation was a success. Until I attempted to start it, I came as far as the booting screen, at which there was a yellow triangle. It didn't go further than that.
I'm unable to access CWM, therefore unable to perform a factory reset.
How would I be able to fix this?
Thanks,
Alex

Have you tried to access download mode? You should try and flash a stock firmware.

Flashing Recovery: Doesn't stick

I've tried flashing recovery via Odin and CWM Recovery and it will reboot into recovery just fine. However, when I let it reboot into android, turn it off, and then go back into recovery, CWM is gone. The phone, however, stays rooted.
Any idea what could be wrong or how to fix this?
Secondly, if I can get into CWM immediately after flashing, is it safe to flash a new ROM at that point or do I need to get CWM to stick first?
Anyone? Any suggestions at all will be appreciated

Sure... You can flash a rom immediately following the flash of cwm.... Did you also install busy box?
Which cwm are you trying to use? 5.8.4.7 seems to do me good....?

Before your phone boots after installing cwm in Odin do a battery pull then boot into recovery (Volume Up+Home+power) then flash your superuser/root package. It will stick then.

I tried using that CWM version as well as an older one. Both work and I can get busy box and superuser installed once it boots up. But when I power down and try to go back into recovery, CWM is gone. I do get to keep root though.

I tried unchecking the auto-reboot button on Odin 4 and 7, and going that route. Both allow me to get into CWM, where I try to flash the recovery v5.zip. Still doesn't stick unfortunately.
My flash counter is up to about 10 now, trying to get CWM to stick..

Flashing 5.8.4.7 after renaming it to recovery.img with mobile odin did the trick for me and it stuck.

Thanks everyone. I used CWM toolkit, reflashed the stock recovery, then used odin 3.07 to re-flash CWM 5.5.0.4 and it stuck.

Galaxy s3 GT bricked?

First off I know I shouldn't have done this before I was sure what I was doing, but I have done it.
I have used chainfires mobile odin pro to flash siyah's latest kernel to my rooted s3. i put the .tar on external sd. Opened mobile odin, opened file, and pressed flash. It said it's dangerous, I pressed continue and the phone immediatly rebooted, and is now stuck on boot loop.
I had never updated the phone from when it first came out, I just rooted and kept stock rom.
Any help much appreciated,
Thanks in advance.
Try to boot into download mode if this works you can flash a stock or custom Rom and kernel through Odin ans it should fix your problem.
Or try to boot into recovery and flash a custom Rom, either way should fix the bootloop.

As a precaution I'm going to ask if you have the American or international model.

Currently in download mode, going to try to install the latest kernel. Do you think that should work, or should I install custom rom?

I would say you just need to flash the kernel if that's all you changed, the Rom should be fine.

Did you choose kernel>open file>flash?

stuck after cwm flushing

Im stuck after i flushed cwm5 through odin! i have just the yellow triangle but nothing after that! im able to get into recovery mode (the blue one) and download mode also but nothing else!
Flash latest official firmware, http://samfirmware.com/ via Odin and will be OK.
After that remember to use safe kernel.
No need to flash stock firmware since you can enter recovery. Simply flash a zip version of a custom kernel like siyah or dorimanx. That comes with a custom version of CWM recovery and should get rid of the softbrick. Thereafter you can flash a custom ROM or stick to stock based on what you want.

People are definitely getting stupider. Also its flash not flush.

I don't really understand why did you need to flash recovery, while it comes updated with the kernel. Basically you need yo flash a kernel with odin now that's compatible with your android version. Not hard to find. Your phone will boot no problem

Go to recovery and flash your rom again with full wipe or go to download mode to flash the stock rom with ODIN.
Good luck

Thanks!
apologies!
have not read the post properly,

cheers!
Change the title of your thread. Your phone was never bricked (bricked phones don't boot/download mode & recovery aren't accessible)/TA did nothing of the sort to your phone.

If you stuck at s2 logo then go to recovery mode and do Wipe Data /Factory reset and Wipe Cache . Reboot . It will work

[Q] HELP: I need help removing Yellow Triangle from Boot

Hello.
This is urgent. I need this phone to work as soon as possible
I'm new to the modding scene, and I have decided to install 5.1.1 Lollipop on my Samsung SII GT-i9100.
I tried to download this ROM off this page: http://forum.xda-developers.com/galaxy-s2/development-derivatives/rom-cyanogenmod-12-t2955551
It says I need :"Kitkat Compatible Recovery". I suspect this was the problem as I had Jellybean 4.1.2, not any KitKat version but I was attempting to install Lollipop 5.1.1 (if any of this makes any sense at all).
This is the page that I found after googling "KitKat Compatible Recovery": http://www.ibtimes.co.uk/install-an...ible-cwm-recovery-galaxy-s2-i9100-how-1434170
The page says to flash "GT-I9100_JB_ClockworkMod-Recovery_6.0.2.9.tar" onto my gt-i9100 using Odin, which is what I did.
When the flash was completed and I saw the "PASS" message in Odin, the page said the phone should reboot automatically. This did not happen. When I tried booting manually, I was shown "Samsung Gallaxy SII GT-I9100" with a yellow triangle and exclamation mark underneath. Then the boot sound played but the screen stayed black. After this the phone screen stayed black and did not boot.
I did some searching on how to remove said triangle, but in all the examples I have found the phone booted. Mine didn't.
All I'm asking is if someone knows how to fix my phone back to normal, or a redirect to a link where this issue is already addressed.
Thanks for your help.
P.S. Recovery and Download are accessible normally

When you boot into recovery which version do you have? If it is the 6.0.2.9 CWM, then flash the CWM 6.0.4.5 mentioned (from recovery) then reboot back into recovery(not system). You should now have CWM 6.0.4.5. Now from this recovery, do a full wipe(factory reset, wipe cache and dalvik cache(from advanced in menu) and format system. Then flash the rom and gapps(if you want them). Then reboot to system.
If you have the stock 3e recovery, you need to enable root access. Let us know if this is the case
I have CM v5.8.1.8, but I flashed 6.0.2.9.
That's weird
Don't worry about the triangle for now, just goto recovery flash a lollipop rom with gapps, after you are in the rom just use the triangle away app and remove it (I have done this loads of times) but be sure you have the correct KitKat recovery or this might not work.

I used this last time I flashed with odin and tick reboot in odin so it reboots automatically, when it is rebooting use the keys to go to recovery and flash the ROM of your choice

Could you explain how to flash it? It's a .zip file not .tar.
If you mean that I should put the .zip in the root of my phone, I can't do that as I when I plug in my phone to my PC I can't access root. (I suspect this is because my phone is not booted and I can't get it to boot)

I know this much, but the problem is that I don't have a ROM on my phone, and I can't access root so I can't place it there. I see an option called "sideload" in the recovery menu, but I don't know what this means and how I could use it.
I have flashed the .tar file you attached. Now I can't access recovery mode.
Okay I've managed to enter recovery by removing the battery and going into download, pressing down-volume to boot and then entering recovery normally. Now what.
I can now enter recovery. What do i do now

GUYS I got it to work. I flashed the two files from the description of this video, and used cm-kernel-09-05-2015-TWRP-2.8.6.0 to flash both of these files. It took some firguring out, but I got there in the end. The ROM is Lollipop 5.1.1 with CyanogenMod version 12.1-20150504-UNOFFICIAL-i9100.
Thanks for all the help you guys supplied, I couldn't have done this without you.
Now enjoy lollipop
