Root Trying to update my Dell Streak to 2.2 from AT&T

[magnificence]

Hi all.

I rooted my Dell Streak with superboot. But when now I want to upgrade to 2.2, but every time I do that it keeps stuck at a black screen.
Did someone had experience with this?

BTW:
I'm with AT&T.

Thank you.

Yo uare trying to do an OTA update while rooted? DONT do it. It will kill your root and possibly brick your device. Every single guide to rooting tells you this. If you want to do an ota update, you need to unroot, flash a stock rom, then update.

Ok thank you. So no I jus nee to unroot it. I thought I flashed a stock rom to he recovery partition, but when I recover the superuser ap is still there. Can anyone tell me how to unroot superboot?

Thank you!

I was rooted and still easily upgraded from 1.6 to 2.2

I talked with dell tech support a while back and got a replacement phone. I already have 2.2 now.
