Power reset or unknown upload mode + phone wont start at all??? - Galaxy S II Q&A, Help & Troubleshooting

PROBLEM???
1) I have an GT I9000G Galaxy SII wid official stock gingerbread for India
2) I was listening to music then suddenly... the phone rebooted itself and displayed the green android logo saying POWER RESET or UNKNOWN UPLOAD MODE
3) now the phone wont turn on despite pressing power button and cant enter into recovery or download mode...
what i have done so far....
1) take out sim... sdcard... battery...
2) connect GSII to laptop with odin 1.8x running
3) put battery back on while pressing both vol up n down button
.... this was supposed to bring back download mode according to http://androidforums.com/vibrant-tips-tricks/223806-guide-fixing-bricks-odin-errors.html
...but no download mode for me....
Anyone have any idea abt what to do???
Request: plz dont tell me to send it to samsung service center....
THANKX FOR UR REPLY

Not Vol up and down!!!! Vol down + home button and power button. This is For download Mode....

power off the phone.
hold the volume down+home+power button. this will boot u into download mode.
ten connect to pc and use odin to flash

c'mon guys... dont tell me you thought i dont know how to enter the download mode.... what u are suggesting is for normal phones (vol down+home+power)... if u read my problem once again u will know that my phone is not turning on at all... nomatter how long i press the power button (battery is fully charged) and there was a strange msg "power reset or unknown upload mode" with green android robot in the screen before all this started!!! so if u have any idea abt how to fix this... do comment... although im considering sending back my s2 to samsung service center... anyways thankx

Try to use a jig.......

hey Gnom2509
you should be more clear because if you search jig it would show a dance or tool or whatever in the search results. rajeshbabushrestha he means a usb jig.

I'm very sorry. My fault. I thought a usb jig. It will force the Download Mode,........maybe.

Update
i took my phone to samsung service center and apparently there was a problem with motherboard... solution: changing motherboard im posting this to help others who might have this type of problem in future :fingers-crossed:

TRY
Remove facebook. I did and it worked.

I had the same thing happening to me too.All i did was pushing the volume down+power+home button and it appeared a warning of OS. It says volume up for download mode or volume down for normal restart.When i choose normal restart it turns back to the way it was before.Thank God

We need a lot more info. What did you flash, how did you flash it. Where did you get the firmware. I ask the last question because according to your profile, you just created this account today. Which tells me you got the firmware elsewhere.

How did you try to enter the Recovery mode?
What key combination?

To boot into recovery you want to release the buttons by the second Samsung logo pop-up. And don't plug into computer. That's for download mode.
Regardless, I don't see recovery being much help to you if Odin is not working for you.
Is odin showing that its successfully flashing your phone? After flashing back to stock with Odin, is the siyah logo at least gone?

Yes, but you need to describe everything you did and everything that happened to make you want to flash back to stock. Without knowing what caused the problem in the first place, we can't help you very much. You say you installed many roms (stock, custom). Your phone probably did not fail randomly. There is probably some event or circumstance you can think of, or change you made, just before it failed. Please be specific.

Hold the Vol+/- & PWR button at the same time, when seeing first boot, keep holding all 3, when past 2nd boot screen, release all 3.
There's no PC involved.
welll the phone was perfectly when one day pum ! turn off and then i cant boot normally. So i try to put in recovery mode and i hold volume upvolume down+power and in the second boot when i see the samsung logo i release and nothing happend. and i see only the samsung galax logo bla bla.. when i turn on the phone normally i can see the samsung logo then de siyah kernel and stack there. if i wait some minutes its restart and do it again. I try to install with odin some stock rom and pass perfectly but the phone still show me the same. its like i didnt change anything. ahhhhhhhhhhhhhh i dont know if u understand me jajjaaj my english is not very good lol im gonna cry

my s3 being restarted even in download mode

my s3 being restarted even in download mode and not let me use odin....
because the time remaining in download mode is like 8 seconds
any ideas?
Very difficult to help you because you haven't given any useful information.
My best guess is your battery is dead or your power button is faulty.

Take the battery out, wait 30 second then replace it. If the phone turns on by itself then the power button is broken.
