Samsung Galaxy S3 won't boot. tried the 3 buttons goes to recovering boot and Samsung, then Galaxy S3, then blank. A few times I got it all the way to the recovery page, then android dies and says no command, then goes blank. Never giving me enough time to scroll down to error messages to delete. Any suggestions? If I try to turn it on sometimes shows a picture of a blank battery, sometimes an almost full green battery or vibrate then nothing. It won't start to use it in anyway.
Here, you may need to flash your recovery again as it seems in problem.
To boot into recovery mode you can use adb command: adb reboot recovery. For this you need minimum requirements for adb. Here you can download this.
Let me make this short but sweet. If you had enabled "USB Debugging" on your device before this started happening to you, then you can flash another recovery using Odin, simple and easy.
GO HERE ONLY if you are 110% sure that you have "USB Debugging = enabled" on your device.

Try this at your own risk. However, it is very unlikely that your device will be damaged if you follow all the instructions as it is mentioned in the procedure. **
If you DO NOT have or cannot remember if you have "USB Debugging = enabled" on your device, then you want to use Samsung KIES to get back into your device. WARNING: Using Samsung KIES WILL delete the data on your device. You can find the process to use Samsung KIES => RIGHT HERE
** I am not held responsible for anything bad that happens to your device such as bricking or whatever. Doing this is entirely up to you. Still, this is a whole lot safer than flashing, since it is an OFFICIAL method of reinstalling a firmware. Any issues you get should be redirected to Samsung, the creator of KIES **
