Galaxy s phone to pc usb connection error screen

I got an error screen after trying to update my kernel. My phone's 3 button recovery doesn't work so i cannot go back to download mode to get it working again. Also i cant get it to go to download mode through SDK manager either. The phone doesn't connect to the computer anymore. Every time i open it it comes up with that error screen and doesn't go. Ive tried everything, taken out the battery and leaving it out for a while putting it back in still nothing. Can someone please help i cant use my phone anymore. Thanks in advance. Azzy
First requirement is Download mode not Recovery mode Home + Vol Down + PWR
That fails you need the download mode recovery jig .

Followed by a flash of stock rom via Odin .

Phone wont boot!!!!

I found an update on kies so i looked around and saw that i had to unroot and un lagfix(oclf) so i did that and started the update, an error stopped the phone from backing up so i carried on without a backup because i dont have anything thats very important on my phone. The update file downloaded and i got to the point where you have to unplug the phone and then plug it back in. I did that and when it turned back on it reached the galaxy s screen then went black and now it just vibrates every couple of minutes.
i already tried taking out battery, sim card, sd card
any ideas?
Sounds like you need Odin.
whats odin?
How does it work?
Factory reset first .
# Also firmware Kies emergency firmware recover .
Or Samsung service centre .
Failure at boot is usually wrong firmware or lagfix on .
ODIN is an alternative unofficial method of installing firmware on your phone .

how can i factorz reset without being able to boot up
how can i use odin to flash samsung firmware back onto my phone
try using the 3 button combo method entering recovery mode by switching your phone off, press up+home+power key for a couple of seconds then it will enter recovery mode, try making a factory reset there, then reboot your phone, try if it will work, if it still doesn't work, then go to the development section and read how to flash a new firmware via odin then.
ive tried the three button combo several times but it just keeps on trying to boot, i think its one of the galaxy s phones that has it disabled
any other way to enter recovery mode
Can you get into download mode ??
Power + Vol Down + Home .
If so read this POST 2 .

Have you tried reading the link JJEgan gave you? (FAQ)
It had a lot of answers.
3-Button-Combo: Buttons must be pressed untill the screen lights up.
Then release all the buttons.

The method in the thread I posted uses adb (via computer) to force your phone into download mode which you then flash a bootloader with working 3br which will then let you into download/recovery indefinitely, it worked for me.
Or you could make/buy a jig- http://forum.xda-developers.com/showthread.php?t=819551
Just to clear out this is not the problem to get into Recovery or Download Mode.
3-Button-Combo: Starting from a powered off phone, buttons must be pressed untill the screen lights up.
Then release all the buttons.

I just plugged the phone into the computer ran adb download.bat and phone was instantly put into download mode and recognised by odin.
If you are not confident or it's not working make/buy yourself a jig, this will put your phone into download mode and you can then flash whatever you wish through odin.
i live in switzerland and wouldnt know where to buy or how to make a download jig
i think im just gonna take it back to the store to get it replaced
learn how to flash with odin next time. i ditch kies a long time ago

Just remove the battery and put it back again and fire it up
edit:
you need to reflash with stock firmware again, check if it the correct firmware to your device before download and flash it

Unplug usb from the phone.
Press the power and volume up and volume down and home buttons at the same
time.
As soon as you feel vibration let go of the volume down button while pressing
the volume up, power and home button until you see the samsung logo, then
let go of all the buttons and it should boot into recovery mode.
If it does not boot to recovery mode after doing the above steps 3-4 times
you will need to press volume down and power button until the phone
goes into "download mode".
Once in download mode you will need to re-flash the stock samsung
firmware again.
But this time make sure you flash the correct official version and model#
for your phone's model.
Good luck, have a great day!

HELP rooted with kingo buttons wont work now

i used kingo root to root my phone and originally encounted the back button s only works with spen issue , but about an hour later after restarting my phone and trying to unroot none of my buttons would work even using my s pen , now my power button no longer will lock my phone or bring up the restart /powerdown option, my volume buttons are unresponsive , my home button does nothing when powered on , and my back and menu buttons still dont respond , but the buttons work to do system commands , (ex:restore mode, or odin mode) so i know they dont need replacing, and phone is not in a case, idk anyone can help would be awesome
see your other post .
Please don't use very old stuff read first .
If you can get into download mode, verify the model # and flash the latest stock ROM from sammobile.com, updato.com, or Samsung-firmware.org using Odin.
