HELPPPPPPPPPPPPPP!!
Can't connect to Kies coz it requires password that i cant enter.

Can you go into download mode or recovery mode normally ?
Did you ever root ? If yes, what kind of things have you flashed like kernel etc.

4.1.2, screen died, replaced it and its working perfectly now

Did you actually replaced the whole lcd assy. Or reseated the ribbon mulri connecror to the board ? I used to have this alot with my blueangel and ended up putting a bit blue tack behind the connector.

[q] at&t s3 dead

I was rooted with CM10.1.0 and was casually using the phone until it randomly turned off. I turned it back on and the only thing that happened was the "Galaxy SIII" screen flashed and turned off again. I popped out the battery multiple times to be welcomed with the same problem again. I can't boot into Download or Recovery at all. Anyone know how to fix this? (btw im on AT&T SGH-i747)
Try another battery.

Please don't provide false or miss leading information.
To OP. Fully charge your battery or use another one if its corrupt.
Try booting up into both recovery or download mode using the proper combination.
Use this guide to get your phone fully working again.

In some instance (very rare) your phones hardware can malfunction, but seeing how it still boots up I doubt its that's.
Follow my guide and you should be fine.

Not without a charged battery. That's why replacing it was the first suggestion.

But it boots up.
As long as a phone is able to boot up its fine.
Like I said please do a little more reading and research and don't spread false information.

What about with it plugged into the charger and try to get to download mode. I thought I bricked my s2, took the battery out but it stayed on. Thought it was possesd bit it was plugged in to USB.
Can't hurt to try.
Definitely recommend download mode with cable plugged in to computer. Are you sure recovery doesn't work while plugged in to power?

Yep. It just loops on the splash screen. I'll try charging it to full and repeating your solutions. (It died off at 80%, very strange). Thanks for your replies though!
Ok guys, seems that my issue isnt the phone being bricked. I left the battery out all night and popped it in the next morning. CM loaded just fine. However after about 10 seconds of it loading, the power menu flashed, i clicked cancel, and then it immediately shut down again, and the usual problem continued. Any thoughts? (btw the phone died at 80% battery the first shut down it had, right now it should have been nearly 100% after charging) Also, connecting it via USB doesn't help at all. Sometimes the blue recovery words flash when i try to boot into recovery, but nothing happens after that.

It could be a bad battery. Might also be the battery contact points. Worse case is something is wrong with power channels on the Mobo. If it is the last then you will have to warranty the phone if you're still covered. I would borrow a battery first to rule out whether or not it is the battery itself.

Also make sure the power button isn't stuck!

The power button seems to operate normally, but that could also be one of the things that are causing problems. Once i find someone nearby with an S3 battery i'll see if it's actually a battery problem (most likely the case).
I'd thought i'd mention this as well, whenever i pop in the battery, the phone vibrates and tries to turn on, but doesnt actually do it. Anyone have any ideas what could be causing this? power button maybe, but battery?
If the battery out all night boots past the splash screen maybe you could, if you haven't, leaving it out and first thing try download mode. I've been in bad spots but this pretty crappy. Probably to technical for me but Good luck. Let us know how you do if none of the posts help.
Found the problem. The power button is always acting as if it's being pushed down when it actually isnt. The phone starts up perfectly when i hold the phone horizontally with the power button facing down. then when i put it back into portrait mode, the power menu flashes, and its turns off. any knowledge on how to fix this then?

Nice!!!
Um I'd say taking apart the phone or mailing back for warranty even try taking it to an att store.. Its hardware and not software so they should replace it

LCD wont work still after replacement

Hello everyone, About 6 months ago I cracked my screen on my phone. I used it for about 3 months after that until the LCD went black. The phone still booted and I can hear notifications coming through, so I figured it was a hardware problem with the LCD. Today I replaced the LCD and it is still just a black screen, and I can hear it booting just fine. I would like to try to restore my phone to factory setting to see if that will help. How can I do so without using the LCD? Does anyone know what other problems this could be? I appreciate the help
It has a custom rom install, I am trying to remember what it is so I can post it on here. I think because its custom I will not be able to use KIES

If you can't even see a boot logo when you first turn it on, restoring factory rom won't help sadly. You have deeper hardware issues then you initially thought ( mainboard possibly or a bad new lcd ).

U can try putting the phone into dl mode by turning it off and holding vol+vol- while plugging it into PC, give it a second and press vol+ then open odin amd see if it connected, if it did flash stock rom with Odin, now just so u know this is a long shot as I doubt it'll help but worth a shot always

Yep. If it's anything like my issue then it looks like multi-colored static ("tv without signal"). The first replacement I ordered did not work. The second worked beautifully. I already knew how to do it because I had already moved one from a water-damaged phone into mine and ordered the first along with a new LCD to repair the water-damaged phone. It took me a little while to isolate just which was which because I had to take apart both phones again.

[Q] Galaxy Nexus screen off after fall

My GN fell down violently... The screen is ok, I mean it is not broken but it is off ! However, the phone is still working.
I restarted it, I am unable to type my PIN code but I am connected via wifi and I can still receive notifications (sound, vibrations and LED), so it seems the phone is working perfectly but I cannot use it anymore since I don't see anything.
I was thinking maybe the screen has been unplugged after the shock, any tutorial on how to "replug" the screen ?
Thanks
Maybe replace the screen or get it checked by a phone doctor!

[Q] Bricked

So I guess I bricked my phone when I tried taking it back to stock... The phone will not turn on, will not respond to any charger, WILL NOT DO ANYTHING............................
Honestly I have taken mine to the point a few times. First time I drained the battery to the point it was there. See if u can get to dl mode plugged in with no battery.
Second time something weird happed at a strange point in the flahs...and I really thought I toasted it.I reluctantly did as it said in the "so u bricked ur epic" thread and un plugged it, removed sd card, removed battery and let it sit for an hour. I am not playing when I said it worked for some reason. If I read it I would not have believed it but that is the way it went. Give it a whirl....noot like u can mess it up more. There is a guy who will recover it if it is really toast...via jtag

So whatever I did to bring it back to stock shut off everything.. it looks like it could be working but no screen, no led charge light, no keyboard light no vibrate on button press.. nothing?????

This just happened to me, after a bad odin back-to-stock trying to fix some problems the phone just turn off, no screen, no leds. The phone is dead, can´t access to download mode either. I change the usb cable but didn't show any sign of life. After about 30 min of giving up, I tried pressing the Turn On/Off + 1 buttons, trying to access Download mode several time just hoping it magically works, and suddenly there it is, Download mode. After that, phone is working.
Not sure is this would help, but it least I tell me experience. Good Luck.

That is what I have seen to. As suggested above... rip the card and battery and let it sit for a while (hr plus I would say) and try again with no battery to get to dl mode.
