This is all thanks to the awesome threads on this website.. No credit of programming will be claimed by me.

*warning* this can be done only if you have a device that forces the samsung galaxy s g or gt i9000 to go in to download mode.

Ok so here is the story, when the samsung galaxy S froyo beta was out I kind of editted the regedit of samsung to be able to install it...

What I didn't know and wasn't noticed by anyone as I've surfed down google to the 200th pages... was that after the reg edit update the Volume down + home button + off switch combination falls of and will not work anymore.

So I waited untill it was out officially in the Netherlands (eindhoven)

What I did was the folowing:

I went to vodafone and they tried to update it. with the force device (big blue box with 12 buttons on it with the buttons 2 and 6 were clicked down).

When they tried to update the phone went off and it lost it's complete firmware. aka PHONE - ! - COMPUTER.. I went home and searched of the web and found here that there was a kind off update.zip. (when I find it I will edit this post and upload it) I downloaded the file and extracted the contents on a SD card. I went back to vodafone and let them force the phone in to download mode again. after that odin instantly recognized and updated the phone to Android 2.2 Froyo update for Galaxy S.

So here are the simple steps.

1. Don't panic.

2. Surf this forum for the update.zip if I still haven't uploaded it. and mainly search for the tag: black screen of death. or phone + ! + computer.

When you have the file. follow step 3.

3. Extract the contents of the update.zip file to the removable SD card of your phone with another device note like root:Sd/update/(files) but like root:sd/(files) the files must be directly available to the phone without having to be searching in to another folder. and plug the sd-card back in the phone.

4. If you have such blue device to force in to download mode then just use odin and update phone. if not, then go to the nearest and trustworthy phone store and make them force it into the download mode... and follow the rest of the steps.

5. step 5 is the most attention worthy part there is: Either bring your own laptop with the correct odin and the correct files and USB cable for when it's in download mode to update it. or either give it to the person behind the counter and let him update it.

6. When froyo is installed give it time to run and scan all it needs to do, otherwise it will lagg and only frustrate you.

7. after couple of minutes froyo is ready for use. after this.look for a reliable lagg fixer because froyo laggs the same way the mind of your mother-in-law does when you're trying to talk sense in to her mind...

If I'm correct after these steps you should be able to use your phone again and have froyo installed and working.

If this hasn't worked, then I advice to either repeat these steps (hence the bring your own laptop) or let the phone-store guy do his thing and force the install. REMEMBER these people usually give up after 1 or 2 try's but it's your phone and they don't care.. so just stand firm and say, I would like you to give it another try..and if he refuses. you can just tell him you won't leave untill he has done it over and over untill it's done or let you self try it and crawl behind the counter.

ALL CREDITS GO TO THE PEOPLE THAT HAVE WRITTEN THE PROGRAMS AND GIVEN ME THE OPPORTUNITY TO COMBINE THE STEPS AND FIX THIS.

But hey if you think the credits belong to me since I wrote this guide. then by all means :P
