From download mode to dead ?

Hi,
yesterday i got my sgs and first i wanted to update it to JM5.
Because 3 of my friends have the same phone i know what to do.
First i tried to get into download mode but it doesn´t work.
I found here in the forum (thread 749470) "Australia Optus Galaxy S no download mode!" that i´m not the only one with this problem.
Someone told me to use "adb reboot download" to enter download mode - and this worked fine. The working android appeared on the screen.
Odin now found the phone and i tried to flash but it always ended with "file analysis....". So I found help in this forum - restart pc, start odin as admin, use another firmware, try other usb port - nothing happened - last thing: remove the battery for 30sec and try again.
NOW: SGS alway shows the same pic: a phone + ! + PC - but PC can´t find phone, phone can´t be switched off - nothing!
What can I do now except taking the phone back to my dealer?
I appended a pic from my display.
Thanks for your help!

if you can not get into download mode, then there is no way to fix it
you'll have to send it back to the store, to have it repaired

hmm, you can press at least the power button for 7-10 seconds, then the phone reboots, mybe you are able to go into download or recovery mode, with those button combinations.
but isn't that icon his screen shows, meant to connect the phone to pc and start kies so kies can fix it? (at least i read sth like that on forum) but if this all doesn'T work i don't know

You can always switch the phone off, pull the battery out. ( Avoid doing so when flashing though. )

This guide is really not all that useful.
Take out the battery, and reboot by first pressing voldown+home and then power and wait until you see the yellow download screen.

I'd recommend not doing anything with a phone that you can't get into download mode from a cold start with. Too much can go wrong. Leave it on stock.

I remember seeing that screen when I thought I had bricked my phone, I think I managed to pull back by removing the battery and trying again.

that is only because your 3 button combination was working
in his case, his 3 buttons are not working
there is a batch of samsung phones that came from factory with the 3 button combo disabled

Having the same issue. Think the stores will replace it under warranty like this?

Can't get to download mode

I have a galaxy S3 and I was having trouble getting past the load screen. I originally got to the download screen and used odin. But now nothing happens the phone doesn't turn off or on. I can't get it to get to download mode so I can try it again. What can I do to get to download mode?
When I plug it into the computer it makes a noise so I assume it sees something.
I was also wondering if a USB download mode jig would force it into download mode?

More information what happened before this occurred? Does the phone turn on at all?

It is voldown+power+home.

Yep, volume up is for recovery

either way i cant get to download or recover mode useing the buttons i can get to download mode with my usb jig or boot in to it using Samsung GS3 ToolKit. Is their a way to boot into recovery mode

You can download quickboot from the market.

Thanks that works but i wonder why i cant boot using the button combo its just strange all the buttons are working. but i can get into recover mde now so that is good

That is strange, I say use Odin and go completely stock, no root, and see if it still acts the same. If so then it might be hardware related.

Hard Bricked?

Hey guys, I just want to ask you how to unbrick this phone.
I tried to port FirefoxOS to our phone, I flashed it successfully, clicked to reboot phone, and BOOM, just black screen, I can't enter Download mode, Recovery, nothing works, even usb to pc is not working. Tried everything and nothing works... I hope you guys will help me.
Even tried homemade jig and it's not working... It is dead or bricked?
>No Download Mode
>No Recovery
>USB is not working too
>Got 1 battery but it was on 80%
>Homemade jig is not working.

i am having the same issue power failure occured while firmware upgrade could you find any solution?

Well i have found some information on the net about using a JIG and plug it inside the usb port of the phone to force it to boot into download mode and then having to flash the firmware of the phone. I haven't tested this theory as yet so i can't leave an answer

Probably JTAG is your only solution or maybe Mediatek have some low tools you can use.

I need help too. Stuck in Odin mode and cant go any where. Tries to bypass the pattern I forgot and dint knw what to do now
