Phone has died? - Galaxy S II Q&A, Help & Troubleshooting

Not sure what has happened here, I am running stock 4.1.2.
The phone locked up so I pulled the battery and restart phone then freezes at the Samsung logo, I tried putting it into recovery mode, it loads as far as the little android man then reboots and again freezes at the Samsung logo,
Anyone any ideas?

What about download mode?
If you can get into, try to flash again stock firmware...

[Q] Bricked all kinds of ways..

The Skinny: updated to JB yesterday, worked great! phone died. wouldn't turn on after charging, kept booting to recovery.. so decided to go back to to stock with odin3 and then re-flash JB.
The Problem Now: stuck on "Over Stock" logo. can't get to recovery, or download.. though odin does still recognize the phone in bricked state, it can't effect any change to the device.
is there any hope??
ferther more..
every once in a while it will power on into download mode, but odin doesn't seem to be doing the trick.. but other times it boots into an "upload mode".
well out of my depth.. someone help!
Google ezbase recovery kit and try that. Even when it's for the i9000 you can use it. You can flash to stock after that.
failed
it failed miserably.. now it shows the GT-I9000 boot screen as it loops infinitely. though on the bright side, download mode is accessible again though even flashing stock wont wipe the GT-I9000 residual effects from it. more suggestions??

[Q] Device won't boot on any firmware/ROM

My friends I9100 has a strange problem: It does boot, but shuts down after first Samsung boot logo. It boots to recovery and download mode, but when I try to flash something (or take backup) in recovery, it shuts down. With Odin, I can flash firmwares normally, but those does same, wont boot. I tried Odin-flashable CM9, latest NEE official, and (first?) JB-leak firmwares.
He says that phone just shutted down right after he opened Facebook, and never booted after that. He was using CM10.2.
What should I try next?
EDIT: Never mind. Problem was battery, tried my own I9100's battery in friends phone, and it worked, also his battery didn't work with my phone.

Galaxy S3 stuck on bootscreen (can't access recovery mode)

Hi, today I tried to downgrade my Galaxy S3 from Cyanogen 12 to stock firmware (So from Lollipop to Jellybean) but now it's stuck on the bootsceen and I can't access the recovery mode, I can just access download mode.
Hi Hencick - Welcome to XDA.
I'll just naturally assume that you're familiar with flashing roms...
Were you running a custom kernel with CM?
Can you access adb functions with a pc?
I have a similar problem on my phone I discovered today. I just get the Samsung logo on screen, it goes off, then comes back (bootloader loop i guess).
It was just sitting on charge. It hasn't done anything for a while other than updates, now when I come to it, it's like this.
I can't get into recovery mode, adb mode, download mode or anything. Just the Samsung logo flashing up, then going and coming back up.
Is this recoverable?
As it it keeps powering up, then off, then back up I'm not even sure I can use Odin on it.
TIA.
Edit: Ok, I can get it into download mode it seems. Only, now I'm not sure what to do! lol

Samsung S3 i9300 Stuck in bootloop

Hey everyone! Big problem..
I have installed CM12, Android 5.1 it's been all fine up until now, I was planning on selling the phone, so I factory reset it, that went well until it tried to turn itself back on afterwards.
My Samsung Galaxy S3 i9300t is stuck in a bootloop. I can not do absolutely anything.
I've tried taking the battery out, holding the three buttons, putting it back in, doing that with a USB, As soon as I turn it on, holding buttons or not it goes straight into a bootloop. I can't use odin to install the custom firmware again as I can't get into recovery or download mode or anything, once it's in the boot loop it stays there..
Any help is appreciated.
Bump?

Please Help! I think I bricked 2 phones one after another.

Soo... I have a S2 and S3. I use the S2, today I woke up for my phone freezing on Samsung Logo. I tried booting Recovery, froze on Team Win logo, so I guessed that something is the software went wrong. I decided to flash some Recovery from Odin and boot into Recovery. I Googled, downloaded one recovery, flashed it via Odin, didn't work, tried another one, didn't work, I would put out the battery every time between tries. And boom it wont turn on, only gets warm in the camera region. So I tried all the combinations of putting it the power with and without battery, pushing all the button combinations etc. I told myself I'll deal with it later, need a phone right now. So I used a spare phone my brother game me, an S3. It had a stock ROM and I wanted to flash JB on it. I rooted the S3, downloaded TWRP for Odin, flashed it with Odin, it didn't work, it booted me to a stock recovery, so I rebooted the phone, it went to Samsung logo, I removed the battery to go faster to Download Mode and try something else, and it wont turn on. What happened and what can I do to fix that? I really need a phone for tomorrow. Please help.
