Hello guys. This is my first time here. I have Samsung Galaxy s3 GT-I9300 . I have problems with my phone. I cannot use it. It shows up every 3 seconds Samsung Galaxy GT-i9300 logo.
I tried Press and hold the Volume Down+Home+Power buttons until a recovery mode screen appears. But when i press volume up to download a new firmware it happens nothing. It shows again logo of samsung. Also i tried to connect with Odin but it connects and disconnects my phone every 3 seconds, i tried other usb the same thing, i tried on other computer the same thing. I recored also the video to tell the issue, please see it :

Please help me .
Thanks a lot, and sorry for my bad english.
 
Welcome to the forums, Robert! :hello:
Now worries about your English, it's just fine. ;)
Are you able to boot normally? Are you rooted?
Do you recall the last version of firmware you were on? (4.2, 4.3?)
Have you tried updating via Kies or OTA?
 
Yeah your english is great.
To me it sounds like a faulty power button.
When the power button is held in or gets stuck it forces a reboot.

What happens when you try recovery mode? (Power, Home and volume UP)
 
No the phone cannot boot. It shows evertime the samsung logo as on video, i cannot do nothing with phone, also when i try to connect with kies it connects and diconnects every 2 seconds.
Thanks a lot for your help
 
If the power switch is shorted, as soon as the phone boots, it will start booting again. I think that's what funkylogik was referring to.

The only solution is to replace the switch. (It's a 79 cent part and about $30 in labor - which is ridiculous, but it takes about the same effort ant time to replace the switch, the screen or the motherboard.)

It's usually not the button being stuck pushed in, but the switch under the button being shorted. (What can you expect from a part that sells for 79 cents retail?)
 
So does the samsung screen appear then disappear when you do that?
I think Rukbat is probably right then and the contacts in the power button are shorted.
Thats a hardware problem. How old is the phone?
