Root Please help!!!!! Root/unroot problems!!

[turnips]

i rooted my samsung galaxy i5801 yesterday and started playing around with it. i downloaded an app called droid tweaker. it had an option to change the dpi on my phone saying it would make the screen look higher quality, so, foolishly, i set it to its highest setting. my phone rebooted and when it turned on it was zoomed right in and i couldn't click on very much, and droid tweaker said that i no longer had root access on my phone so i couldn't get back on that to change it back. I've tried everything, even a full factory reset! is there anything i can do????

Can you get to the recovery/pre-boot menu? Most often it is accessible by first turning the device off, then holding down two buttons at the same time, usually volume down and power, sometimes slightly different.

If you can get in there, and want to do a factory data reset, first do a wipe of caches, then try the reset again.

I think to get to the recovery menu hold the following buttons:

Volume down + Volume Up + Home + Power

Let go of the power button once the phone turns on.
