[Q] Yellow Triangle at boot - AT&T Samsung Galaxy S II SGH-I777

First off I see on this forum that people freak the hell out when you post something that may possibly have been posted at one point in the past, so let me assure you I've searched this forum and the internet in general looking for help with this problem, and found nothing helpful.
I read the FAQ, and the sections here:
I've rooted now why do I have an exclamation point on my loading screen?
Anytime you flash a non-stock kernel in download mode this will appear.

Which linked me to a page that said:
Flash the stock kernel using Odin or Heimdall. Since this kernel autoroots the system image, you'll retain root.
Click to expand...
Click to collapse
Where do I get a stock Kernel? How exactly do I do this?
Then the next step says something that is completely greek to me, it doesn't seem to have much to do with fixing the Yellow Triangle problem.
I also scoured the internet looking for a fix and most of it involves the International version of the phone.
Any help would be greatly appreciated, I'd love to get rid of that annoying little triangle.

From my understanding I rooted this device and got it after root. Even though I retained stock ROM

No, you clearly did not read the FAQ and all stickies in this forum as one should do whenever posting to a forum on the Internet, since not only is your question answered in the FAQ, there's an entire guide as a separate sticky post at the top of this forum!

this will get rid of the yellow triangle but will not reset the counter.

I absolutely DID read the FAQ.
My question is not answered in the FAQ, and if you would have read it, you'd know that.
I've looked at every sticky in the forum, the one at the top does not address this.
Can I get a link to the sticky? If it's the one posted below that doesn't help me either. I've already rooted and installed Cyanogen 7 on my phone, now all I need to do is get rid of the yellow triangle
I mean, would it have taken you as long to help me out as it did to come on here and yell at me? I read over the forums for hours, did google searches, so I came here.
Isn't this a place to get help? If so, why are there dickheads just trying to **** in your cereal here?

Thank you Defnow, that was extremely helpful.

---

It worked, I now have a splash screen with no triangle, but unfortunately it doesn't get any further than that. I now just have a black screen after the spash screen. Any ideas on how to remedy this?

---

Will using a jig get rid of the ROM and kernel I already have flashed onto my phone, or will it just remove the YT and reset the counter? I've been curious about this for a while now.

Just yt and counter. Won't touch anything else.

Only the yt and it will reset the counter.

Please use the new ZergRush method to root your phone. It's much safer and does not require kernel swap or flash anything. It will not show YT because you didn't flash anything at all.
As for OP, you need read MUCH more before start doing things like flashing ROM or kernel. Take any shortcut will only put you in a fast track to brick(ed) land which from what I saw is exactly where you are now.

The issue is you rooted in a way that tripped the flash counter.
Which is discussed in the return to stock thread.
And flashing the *stock kernel* back will remove the yellow triangle. Or using a *usb jig*.
Which is discussed.
Your problem is you flashed cm7 before you fixed the yellow triangle issue. The cm7 thread states that it does not support the *stock kernel*. To flash the *stock kernel* would remove cwm, which removes the ability to use cwm (kinda obvious, I know. Just trying to educate the obvious noobs). And since there's no way to boot cm7 on the i777 with stock kernel, you'd be stuck and have to use download mode and odin to return to stock, as you would have no other options.
From the above information, all from existing threads, you have two options.
Option 1
Buy a *usb jig*. Undoes tripping the flash counter and gets rid of the yellow triangle.
Option 2
Use odin to flash back to stock, which will completely remove cm7. The flash counter will still be tripped.
Obviously the *usb jig* will be easier to use and will undo tripping the flash counter. Though it costs money, you have to wait for it to ship, and so far at&t has not been caring about a tripped flash counter.
Thank you for doing research before posting. Understand you read the answer and just did not get it. So when you post and say you've read the stickys and it's not covered, when we know it is, what are we to say? The information is in there. Literally there is a step by step write up dealing with removing the yellow triangle.

Jig worked great for me...might come in handy down the road as well.

So... let me get this straight.
1. You didnt read the FAQs or stickies that CLEARLY fix/cure/answer your question.
2. Decided to post a thread asking how to get rid of the yellow triangle and for a stock kernel.
3. Didnt read or click on the two posts above this one (that Im quoting) that was posted 45 and 40 minutes before this post.
4. Decided to flame the ones that posted in this thread to help you by calling them "dickheads" and use a horrible analogy to sum things up.
Did I miss anything? You have been here for 9 months and only 4 posts (all of them in this thread) so Im assuming that you do reading here and not posting... so you should have read the FAQs and stickies at the top of the forums. Its not a good idea to flame people for trying to help you. Its not their fault that you didnt read what you were supposed to, or for not reading the two posts above yours that actually point you in the right direction.
Infraction issued due to flaming.
