What happens when you plug it in your computer? Does device manager recognized use it or is it completely dead? If its dead, take it back to samsung

Dead battery ??? Its unusual for a flash to result in nothing at all .
Usb recovery jig may get you to download mode .

thanks guys , i thought so ..but how could i use odin when i cant switch on "Downloading" screen ? ( because its reset like crazy ) - sorry for my bad english. is there some way to stop booting ?
Have you gotten into download mode? I have to assume that you haven't yet as it probably resets under normal boot, I would think that it wouldn't in download mode but you have to get there first to find out.
- If you can't get into download mode with the button combo's you might wanna look into purchasing a jig. Good luck!
Take your battery out. Hold the Volume buttons down, place the battery back in. Plug the cable in. This should get you to dl mode, works for me.
you could also plug the cable in first then put the battery in. If you can't get it with this, like mentioned earlier, you need a jig.
since you tried going to 2.3..... it might have played with your bootloaders too.... if the above doesn't get you into dl mode.... pull battery, replace battery.... hold VOL UP and POWER

Relax..... your going to be fine. Things like this is what started it all for me
for 2.2 download mode for odin
power off phone
pull out battery
GRAB THIS STUFF : http://forum.xda-developers.com/showthread.php?t=1047087
turn on odin
attach phone to pc with usb cable
now while holding down both volume buttons put battery back in.
now you should be in download mode and go back to stock with odin from here!
make sure u put the proper tar file in pit and the .pda file in pda in there proper places on odin and ur set to go.
Enjoy and also make sure u have the proper samsung drivers
For gb dl mode
different with GB bootloaders
volume up + power for download
volume down + power for recovery
It's either Vol-up and plug in USB cable while phone is OFF.
Vol-down and plug in USB with phone OFF.
Vol-Up and Vol-Down and plug in USB with the phone off.
Best way is to pull the battery then put battery back in, then hit the volume button, then plug in USB last.

all ele fails see if you can be as lucky as me and ring Samsung tell them you updated via Kies it restarted and it hasnt come back on since, say it was fully charged and you have tried different batteries, i just got away with it lol, also try n grab a usb jig see if that works
it doesnt even starts, black screen
Strangely that happened to me in 1 ocasion, I'll just take out the battery, put it again without turning on the device, leave it connected to the charger for a few hours and then turning on and it revived!
no not working in my case
best way and save way to flash the rom is CMW odin is risky
is there any other flash tool besides oden?

hey dude try this.
1)Remove the battery from the phone.
2) hold the three button combo (VOL dwn + home + pwrbutton) simultaneously.
3) put the battery into phone while holding those buttons.
4) wait for a cpl of secs and see if the phone enters dwnld mode.
5) if dwnld mode shows up then u can use ODIN to flash back a stock ICS rom.
6) if not buy a cheap USB jig from Ebay and try.
Nothin and i buy usb jig and again nothing

then u should approach a nearest samsung service center if ur phone is still under warranty.
and just tell them that while updating on OTA the phone suddenly went blanck and wont turn on
The problem is i dont have warranty :S Can i try on jtag or just to trash my phone?

Phone unable to power up

I recently flash my Samsung Galaxy S3 to MIUI ROM (miui_i9300_3.6.21_92f38a8c3a_4.1), it is able to flash successfully. However, when in the middle of setting up the phone, the phone hang and auto power off by itself. I unable to power up after that.
I think my phone previous is the stock ROM ICS if not wrong.
I can't even go into download mode by pressing and holding Home, Vol down and Power button. I have also try remove battery and put it back and still can't go to download mode.
Anyone have any solution to recover my phone?
Btw, my phone already over the warranty period, so really appreciate if anyone can help me on this. Thanks!

Verify if you have a short between battery connectors on the motherboard, you will need a multimeter to check, it happened to me and i removed C565 - 22uf, check again for short circuit, if still running hot check power ic max8997 - need to be replaced!
