Unroot/SD Card Help!!

[kingsuffolk]

I'm trying to unroot my phone to send it back for warranty issues. The phone won't read any SD Card. Is there any possible way to unroot without access to the SD Card. Thanks for all your help.

There is, but it's a tedious process.

So no SD access at all?

Not at all. Tried 3 different SD cards.
Is there a way to flash using PC?

Thank you for all of your assistants, but I found out how to load the RUU and HBOOT through command prompt.
