I have SAMSUNG galaxy S3 mini GT-I8190 vietnam it has been hard bricked its not turn on cant't enter into recovery mode and cant' enter into download mode its battery,touch screen and power button is OK but phone is in dead condition please help

Welcome to Android Central! What do you mean the screen, battery, and power button are ok? What happens when you try to power on? Does it freeze at the Samsung logo?

no its not freez on samsung logo its not turn on when i press power button it do nothing only black screen

How do you know the battery is ok? Have you already tried a new or different battery?

yes i buy a new battery and its working properly and i tried a different one

So if it works with a new battery, then that would suggest the old battery has failed, which is therefore why the phone wouldn't turn on. Or am I misunderstanding you?

last time my phone samsung galaxy s3 mini gets a problem it freeze on the samsung logo half circle and restart and again stuck on sumsung logo half circle then i tried to flash it with odin after flashing complete it does not do anything just black screen i reinsert the battery but it do nothing just black screen
i was thinking that its software was corrupted now my phone is not in bootable condition please help

Oh I see. I"m sorry, but I'm not sure if I'll be able to help you with that. If you don't get a good answer here, try the forums at XDA-developers.com as well. Good luck!
