ROM Manager recovery boot failed
Secure booting Error!
Cause: boot certification verify

Any help pls

You can only install CWM when coming from a Gingerbread official ROM. Meaning you have to follow unbricking instructions to downgrade to an official Gingerbread ROM, then flash CWM using that. Currently there is no CWM-flashable version of Bell's ICS though, but one will probably pop up soon.

Once you do this method is it possible to unroot without going through the unbricking guide and reflashing the ROM?

Edit: NVM it looks like you can do it with the SU app, it says so on the second last page of original thread.

@drumist,
I think he's asking if there's a version of CWM that can be flashed while on official ICS and the answer to that is no, unfortunately not with the ****ty ICS bootloader.
