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?

Started two days ago. Phone would randomly power off and boot back up. Finally it shut off and would not power back on. I had Cm11 installed with CWM 4.0.4.6. The phone powers on after inserting the battery. The Samsung logo flashes and then it shows the "Galaxy S3" logo with the CM logo below it. The phone the powers off. I have done a factory reset, cleared both caches, formatted the system folder, flashed SlimKat from recovery and tried another known good battery. At this point I figured I would reflash CWM but if I put the phone into download mode, it powers off after just a few seconds as well.
If I boot the phone into CWM, the phone stays on as long as I want it to so it makes me think this might be fixable. Just need some help.
Ask in your device forums.
My apologies. Didnt realize there was another S3 board. Found and posted there.
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
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.
Hello, yesterday while i was cycling to work my phone suddenly turned off. i tried to turn it on but it didnt so i got the battery out for a few seconds and i tried again. my phone was in bootloop after that, at work i tried to flash few different stock firmwares on it but none of them worked since i cant access Recovery mode. when i do the buttom combination to access recovery mode (WMshua) it just shows a huge amount of white lines of text and goes back into bootloop after. i also tried to flash other recoveries using ODIN but none of them seemed to change anything. im quite out of possibilities and im not sure what to do.
Thanks in advance, Caikorn.
I had a korean 4.4 rom on my galaxy s3, it was rooted I tried to go to recovery to try out cm 14.1, I couldnt get in trough key combo so I used application, did everything like many times before and after all installed, the phone rebooted and got stuck at cm loading screen. tried to leave battery out over night and then inserted battery and let phone turned on for a while and nothing worked, still could not get to recovery or download (none of the keys are working) so i load up odin and insert the jig, i get to download mode, try to reflash twrp, nothing i tried cwm and still nothing. I install everything back to stock and i get stuck at samsung logo (sound of the bootup silences halfway trough but led slowly fades and back on aggain )
So to cut it short, everything is working but i cant get the phone to boot and the key combo doesnt work (keys are ok and functioning properly otherwise) is there any way to get to recovery if you cant boot the phone and key combo doesnt work ?
Nope. There is no way to communicate with the device. You'll have to fix the buttons.
Beamed in by telepathy.
How do I do that ? The keys as I said are working, I have tested them before the brick. What could be the reason for the phone not going into download/recovery mode?
