What happens when you try to boot up?

 

whoops is right. but your system still should be working unless you had link2sd or something like that set up. What happened when you tried restarting? Get hung up on Samsung screen, bootloop, etc? Did you try booting into CWM (vol. down, back, power keys)?

Can you get into CWM? If so, I know there are a few CWM backups people have uploaded here; you can flash those.

Otherwise, you may need to flash the pre-rooted tar file with odin, then flash the CWM and go from there. Good luck "dumby".

 

ODIN won't fix anything, it just flashes CWM to the phone.

Put a ROM on your SD card, boot into CWM, and flash it. Next time make a back-up of your SD card before you start messing around with anything.

 

I did the same thing yesterday, I just put the cm7 cwm and kernel reboot to that cwm version then flash stock ++ or CM 7.2.
fixed mine and its overclocked

that sucked, lost all my backups, pics and music, lol

 

So, go to a store and pick up a card reader for cheap, or a MicroSD to SD adapter and use a digital camera or something.

No way to put it back to stock without being able to flash the stock ROM to the phone to fix your error, and you need to put the ROM on the SD card for that.

 

To simply things, if you have access to a computer, just download any rom and cwm you want (depending on your preference) connect your phone via USB, boot into cwm, go to mounts and storage and navigate to mount USB storage (or something of that sort) you will be able to move what you want to your SD that way. Flash whatever you chose and your back in action
