[Q] Help - stuck on yellow triangle when flashed ROMS - Galaxy S II Q&A, Help & Troubleshooting

I was running CM nightlies, and all working fine. Whilst trying to flash one, it got stuck on the yellow triangle screen.
Now I cant flash any other ROMS. I used ODIN to revert to stock and rooted again, but when trying to boot after flashing it just gets stuck on the yellow triangle screen.
I've tried several ROMS (CM7, VillainRom, MIUI), all the same problem. I can always go back to ODIN to flash stock, but can't flash anything else.
I've also got nandroid backups of CM, that once restored will also get stuck on triangle.
Something must be corrupt - but any idea what it could be, or how I can solve this?
Thanks
Jamie

[Q] CM7 Bootloop

Well, this is what happened.
My phone was using cMiui 4.1.2 with the default kernel, and this morning I tried to flash CM7. I wiped everything as always before flashing, after I pushed reboot system and it got stuck in the "Galaxy s2" screen and keeps turning on and off endlessly.
I pulled out the battery, try to get back into recovery, but it hadn't been a successful attempt.
I stayed claim and flash back to stock 4.0.4 via Odin, god-bless I made it through.
I installed a custom kernel and flash to CM9 for temporarily use. Now I don't know what to do.
I really want to try the taste of CM7, please help.
Edit: I also tried various way of flashing, such as flash a codeworkx kernel before flashing, and flash back into GB 2.3.5 before flashing CM7, both didn't work out
it was making me crazy for weeks and here is the solution i found 5 minutes ago :
when it gets bootloop
go to download mod and flash siyah 2.6.14 via odin!
then it boots.

[Q] I9100 bootloop after flashing stock 4.0.3

Hi all,
Having a strange issue. After giving my phone in for servicing, Samsung wiped it and put 2.3.6 Gingerbread back on. Naturally, I got a stock 4.0.3 file to flash (XXLPQ at first) and did so (well-versed with all of this). However, ever since that first flash, the phone's been stuck in a bootloop, usually at the "Installing applications" screen, but sometimes just a normal bootloop at splash. I've re-flashed with different stock ROMs, followed the soft-brick guide and flashed the bootloader and kernel, nothing's working. The first flash was clean, but after that I haven't been able to access recovery, only DL mode, so no way to wipe first.
Any thoughts?
Thanks
Change CSC it will wipe your data or XXLSJ with all components(PDA,PHONE,CSC)

Stuck at first boot screen

When trying to flash a stock rom on a rooted i9100 with Mobile Odin Pro 3.65 it gets stuck at first boot screen.
Even when trying to flash stock 4.0.3 and also with stock 4.1.2 roms it still does the same thing: it gets stuck at first boot screen. Even if i check the wipes and everything. Any information on this?

[Q] Phone Loops at Vibrant Logo

I tried ODIN and successfully got it back to stock rom. But the phone keeps looping back to the Vibrant logo screen. The method I used worked for me for the past three years, it started acting weird when all of a sudden an ICS custom rom from MIUI hanged on me. And then I was unable to get my phone working!
Is my phone permanently bricked?!

Can you get into recovery? Did you flash a custom gb boot loader? You wipe data and cache? You could try Odin again and flash stock with the correct pit file and re partition checked I've done this many times and have not had this problem you might just have had a corrupt flash like I've read Odin has been known to fail

G925F won't return to 100% stock

So my G925F got bricked recently by updating the phone to 5.1.1 UK BTU firmware (G925FXXU2BOFJ) and the phone would not boot up. It was stuck on the boot logo. I did hours of research and finally managed to get it working by flashing Unibase Kernel.
Now the problem I am facing is that I want the phone back to 100% stock. Even unrooting the phone won't work because Unibase will reinstall SuperUser during restart. If I reinstall 5.1.1 using Odin it will hang on boot logo until I flash it with a custom Kernel, in my case Unibase did the trick.
Ive also flashed the phone using Samsung SmartSwitch with original firmware it still fails to boot until its flashed thereafter with a custom Kernel (UniBase)
Ive also tried the solution of removing hidden.img from firmware then repacking and flashing it, still seems to be the same problem (hanging on boot logo) Ive also tried to hard reset phone after flashing and yet its still faces the same problem. Is there a stock Kernel or any other solution anyone may know?
All help is appreciated and I will be happy to try any solution or method posted. Cheers
flash stock firmware with odin but uncheck auto-reboot. Once its done boot into recovery, clear cache, factory reset and it should boot

Thanks guys, Ive tried both of your solutions, unfortunately the problem still exists. The phone will hang on
"Powered by Android" boot logo until I flash it with a custom Kernel. Weird problem
Ive checked, its definitely the boot.img causing the problem. Unibase flashes modified boot.img which turns the phone on

Out of interest, why do you need to return it to 100% stock?
