I got the same problem. screen keeps turning grey after few seconds in S/W mode.

I had the same problem. reinserting the battery when in sw-upgrade mode helped for me.

Can you get into recovery? That is volume up + home + power
You are a genius in trying to use vooodo made for I9000 i assume!!!
Sent from my GT-I9003 using XDA App
am sory but i did not know and i cant go into recovery mode worst everytime booting my galaxy s i9003 its showing the black screen of death
firstly dont panic....We do make mistakes and when we panic we dont follow steps correctly... Take out battery and press power key for 15-20 sec....Then insert battery and try to go to download mode...
ron is right....you might have tried to flash vodoo for 9000 and might have corrupted your system...in this case you need to go to samsung service center and tell them that you were playing a game or something and phone switched off...After wards you are trying to boot it and its not coming up...
THis is the only way you can get warranty....Regarding your father....You should be spanked
Remove your battery...put it back and try going into download mode..
Sent from my GT-I9003 using XDA App
its showing the same as for warranty my phone is rooted does that void my warranty ....i tried removing my battey and put it back when turning on its showing the same black screen of death O_O
for the file u gave me to download can it solve the black screen problem??

No it wont unless you get into download mode

now what will i do -_-'' !!!
Wow, if you flashed a I9000 kernel, then your a goner. Make sure you hold the vol down+home first, then 1 sec later, hold the power button till you see the yellow triangle pop up. It will work. You aren't doing it right.
On another note, Father's hand is itching :O!
Are you pressing the right keys to get into download mode...first press and hold volume down...then simultaneously press the home key abd hold while holding both the keys now...press power button...release after you see a picture of download
Sent from my GT-I9003 using XDA App
its in downloading mode now phewwwwwwwwwwwwwwwww
what next ?
If you have got to the download mode then you can install either a stock firmware XXKB3 or try to do recovery.

Software upgrade mode

Here in XDA, some people telling to access software upgrade .. press volume + button and plug in USB cable
But some people telling press volume + button and plug in USB cable (after removing battery)
which is correct to follow to avoid phone brick problems ?
Any XDA Senior member Reply is appreciated.

Hold the volume+ button and plug in that should allow you to enter s/w upgrade mode.

I'm rather sure you have problems with reading.
- turn your OB off
- remove the back
- take the battery out
- hold vol+ button and plug USB in
It is not always needed to remove the battery but it helps sometimes especially when nothing else works, had it once myselfe where that was the only way I could get into SW upgrade mode.

Same problem here, phone is completely dead.
When holding the power button, nothing is happening.
Also not when removing battery, holding VOL+ and inserting the USB cable.
I think, I need to send it to the service center.

If OB is doing nothing at all it's a hard brick => service.
If OB's screen is showing something like 'security error' it's a soft brick => you can do a lot (like 'sw update' and use SFT)
So it's a difference of more than 5$.

What app do you use to perform those functions.What is that other way..
Can i enter into cwm recovery.
i want to flash a rom but i can't as power button isn't working
Take care never turn ur phone and there is an app but needs root do this and I cant remember its name now sry
Sent from my GT-S6500D using xda app-developers app
Im a master in this field so follow my instructions:
1-you have to flash a cwm on your device so if you dont have it put off the battery then put it back if the phone starts automatically it means the power button is always pressed so just keep pressed the home button and the volume down button to enter in download mode.
Once in download mode connect your device to your pc using the usb cable.
Now follow a tutorial to flash the cwm using odin if you dont know how to do it.
2-once obtained the cmw put off the battery and then put it back and keep pressed the home button to enter in recovery mode. If u have the cwm there are no problems cuz now you just have to reboot your phone and save a rom in your sd card then go in recovery mode and flash it.
3-once you have a custom rom just download the android terminal emulator and type the following lines if you want to reboot your phone:
su
Press enter and allow superuser
reboot
Press enter to reboot your phone.
If you want to reboot in recovery mode typw this:
su
Press enter
reboot recovery
Press enter and your phone will reboot in recovery mode
If you dont want to use the terminal emulator just download an app from the play store called "reboot menu" and for lock/unlock your device use the notification power widget or apps like "proximity sensor screen off" thats all

Sent from my Galaxy MINI q
I tried hitting my galaxy mini to wall or edge of table still no luck. Is there any video to do this?

after flashing, the phone does not power up. nothing.

i think it's my fault, but maybe i can do something to unbreak it?
here it goes.
i downloaded the latest build from this rom:
http://forum.xda-developers.com/showthread.php?t=2199575
when first i entered CWM and wiping everything, i try to flash the rom, but the installation aborted with 'error 7'
so i look for error 7 in google, and get into this video which explain how to bypass it:
http://www.youtube.com/watch?v=QW1znjDLe-k
i did exactly what he said, and remove the assert till the ' ; '
after that i ziped it back and send it again to my phone, and again get into CWM.
the installation went OK.
it said so .
i did a reboot, but then the phone didn't power up.
he is very dead
is it final, or i can do something to revive it?
thanks!
Status 7 error is due to a corrupt rom file. Download the rom again, place it on sd card & flash again.

not working, because after i insert the battery, and start odin, it don't recognize any device that connected to the computer.
but, if i press the Volume UP + home + power, it install USB drivers of the phone, and in odin i see that it know that something is connected to the computer in: com 39.
but i cant flash the firmware, because it's stuck on setup connection...

Downloading mode is volume down+home+power & in doing this, you must see downloading written in yellow letters on your screen. Then you're good to go.

check that have you installed the USB driver ? because it matters a lot...
You can download it from here

If it connects to the PC then first rectangle becomes yellow.
Best Luck!!!
