[Q] How Do I Fix My AT&T Samsung Galaxy S3? Help! - General Questions and Answers

Alright So I Was On My AT&T Samsung Galaxy S3 The Night Before The Tragic Frustration Came Along . It Was Working Perfectly Fine. I Put It To Charge & Went to Sleep. Next Morning When I Pressed The Wake Up Button But It Failed To Respond. I Held Volume + , Home Button & Power Button To Shut Off & Restart. I Seen The Samsung Logo But It Went Dark Right After. I Can Hear It Load Up & Hear The Phone Haptic FeedBacks & All But Nothing Comes Up On The Screen. I Looked EveryWhere Online Nothing Help. I Cant Get into Recovery Mode But I Can Get Into Download Mode. But Problem Is, My PC Doesn't Recognize It, I Do Have The Drivers Installed. I Even Have Samsung GS3 Toolkit. Nothing Works. Please Help!!

Phone (semi?)Bricked and Wont Go into Download Mode after Voodoo failed

I decided to install VooDoo lagfix on my new captivate when it still didn't have anything on it to minimize potential loss of information. I downloaded the lagfix, got it started, then the damn battery popped out when I got off my bed a few min into the mod. Immediately I felt like an idiot. Now, when I start my phone I get this sequence: ATT world phone screen, then a GALAXY S / GT-I9000 / SAMSUNG screen which it freezes on.
I have odin3 v1.7, but I'm unable to get it to Download Mode with any of the methods I've found (I don't know what I need for adb or what it is though...).
If I attempt to go go into download mode with Vol + & Power it shows a circle of radial lines, then it goes to a battery with the circle of radial lines (and I'm still holding both Vol + & power), then a black screen, then repeats what seems an indefinite amount of times. If I release the Power or Vol buttons it stays black for a couple seconds then it goes to the charging battery screen.
If I plug it in and turn it on with odin3 running, the phone stays on the frozen GALAXY S screen, odin3 recognizes it as COM6 but wont allow Start.
Any help would be great. My intuition says it has to be fixable if it's software.
Not sure if this will help, but earlier today I installed a theme on my phone that wasn't supported by my kernel by accident. The phone went to the AT&T World Phone screen then hit the Samsung Galaxy S screen and froze. I pulled the battery out to unfreeze the phone and then I put it back in after a few seconds and turned the phone on. I immediatly did the three button method and held it down so the phone did the AT&T World Phone/Samsung Galaxy S thing. I kept my fingers on them and the phone rebooted again (which is supposed to happen) and I kept the three buttons held down so again, it rebooted. After the second reboot I immediately took my fingers off the buttons when the AT&T World Phone screen popped up and I got into recovery. Now, this is a theme so it's totally different, but it's worth a shot and hopefully it works for you.
But if that doesn't work I still wouldn't worry as you most likely didn't brick your phone. If it was bricked it wouldn't be turning on at all and Odin is reading it at least so I'm sure with the right help if my method doesn't work, you can fix it.
Hopes this helps you man!

[Q] My Tab Plus Stuck at Boot

Got a tab plus in completely stock condition. Been working well for well over 2 years now. Yesterday I noticed that the screen is displaying "Warning!! A custom OS scan cause critical problems..... Volume Up to continue, Volume Down: cancel (restart tablet)" The screen wouldn't get switched off. Neither the volume up or Volume down or power works. I let the battery completely drain till the tab got switched off. Then tried to charge, after a few seconds of the charging animation, the same screen comes back again.
Tried the Power+volume up, Power+Volume down, Power+Volume up+Volume down combinations. Nothing works. Never had a sim in the device. Removed the sdcard and tried. No luck.
What has gone wrong? Any help will be greatly appreciated.
Bump. Any help will be nice
If you can, try to save everything you want off of it. Then try to factory reset it.

Samsung Logo Splash Screen and Keeps rebooting

Hi,
Two days ago I got the official update of jelly beam 4.3 to my Samsung galaxy s3. Today morning I switched on the phone its worked fine. But after 2 hours suddenly my phone was restarted and Samsung Logo Splash Screen (Samsung galaxy S3 GT-I9300T) and Keeps rebooting. So I remove the battery and insert it after a few second. After that the phone worked fine and again the same problem happened.
If I remove the battery, phone switch off. And if I insert the battery, phone switch on itself and keep restarting.
I try to open the (Home + Volume Up+ power ON) button option. But is not working. If I plug the phone to charge, gray battery shows and again restarting to charge…. (I mean, phone won’t stay in a stage).
So can you please let me know it’s a software problem or hardware problem?
If it’s a software how fix it ? ( I tried the emergency firmware recovery through kies, but kies couldn’t fine my phone)

Samsung Galaxy Note 10.1 N8000 Stuck in Frozen State.

Hello people, i really need some help on Reviving my Samsung Note 10.1 N8000. Ive been using it with the latest Version of Android from samsung for almost a year. Device was bought 2012.
One night, after doing some email checking and browsing, the battery got drained and the Device shut down as i fell asleep. I plug the charger around 5 hours later that morning and waited for battery capacity to reach 100% before switching the note on.
Upon doing so, my Note, would boot through the moving samsung emblem as it would normaly do, but would get stuck in the Samsung Logo... indefinitely or until it runs out of juice again i would assume since Device got Warm after around 15 minutes..
I have tried the following Key Combinations to boot / reset or get into restore mode...
Hold Power On Button = Turns on Device, will shut down ONLY if Charger is inserted. Charging the battery would work as it normally would. (Visible battery icon while charging)
Hold Power On Button + volume (+) Key = Device would constantly be in boot loop (initial moving samsung splash over and over). Letting go of all keys, Device would freeze up to Samsung logo..... No Recovery Mode
Hold Power Button + volume (-) key = Brings device to Odin mode, ive tried flashing various Stock roms up to the latest using Different Odin Versions, All FAIL. Odin would recognize the device.... BUT.... none of my efforts seemed to work. Once i click START.... id get a FAIL in 2 seconds. I've been reading that i need it to be on USB Debugging mode... but how can i do that, given the circumstances?
Is there somthing i am missing? Should i call it quits? Im really trying my best... but ive seemed to come into a dead end trying to revive this. If there are other options i havent explored, please to tell me. I would appreciate any help regarding this.
Thanks alot
Please.... anyone?
