[Q] Samsung Galaxy S Showcase Problem.

---

So I've run into quite an annoying problem- I can't install applications from the market. Last night, I had my phone plugged into my computer and I don't THINK I had the SD mounted, but I've been wrong before. Anyways, I went to disconnect it and instead of dismounting then unplugging, I just unplugged. Since then, if I try to download something, the notification bar will show that the app is downloading, for a second, then it just disappears. My phone is rooted, no custom rom though, and I'm not running Apps2SD. Also, I'm running Ubuntu 10.10 x64 on my computer.
This has happened once before, and I had to tinker with popping my SD card out and rebooting the phone a few different ways before it finally started acting right again. I'm looking for help because 1) I can't remember exactly how I did it and 2) I figured I might as well try to find out if anyone here knows what I could do to fix it.
Thanks in advance.

Galaxy S Showcase stuck at very first screens

---

Afternoon guys, I did some browsing and searching and cannot seem to find a way to fix this, so here goes:

Samsung Galaxy S i500, Showcase with Cellular South.

It is rooted, with the original ROM/Kernel.

Yesterday, I was attempting to follow the guide on getting ClockWorkMod on it (http://forum.xda-developers.com/showthread.php?t=860250) and when I finally got the final command to work, the phone rebooted, and has since been doing VERY little.

Power Button = SAMSUNG... No vibrate, No change.
Vol Up/Down + Power = SAMSUNG... No vibrate, word flashes, release power (steps to enter recovery or download), SAMSUNG screen remains. Still no vibrate or anything.
Plug in = Grey battery with "loading" circle with no animation of any kind. It is charging though.
Plug in + Vol for recovery/download mode = still just grey Battery not moving.

In all attempts, I have left it trying for anywhere between 30 mins to 4 hours... I cannot get to anything but those 3 results. (samsung, samsung w/ 1 flash, and grey battery).

If I can get it into Download, I can Odin it, or recovery to reset to factory... but I need to get to one. Any and all help is appreciated.
