Root How to undo Ryans OCLF in shell only?

[amplivibe]

Hello, I'm new to this forum and I was wondering if anybody can help me out with this one.

I installed OCLF V2+ and all is great. However, one day I turned on the phone and I think it's physically broken. The symptoms are:

- Only half screen image
- Other half screen has strange stripes
- The phone doesn't go past the spash screen
- It will boot in recovery and download mode. Here there's still only half a screen

So what I want to do is undo the lag fix, remove ext2 tools and unroot the phone before I go back to the store. Can anybody help me with this?

I CAN start in recovery mode and use adb shell to go to the phone shell! So I suppose I have to do the above steps from the shell!

Reflash the phone.

Reflash the phone.

Thanks, a "clear data" in the recovery mode works too (I didn't flash it to another firmware).
