Assuming you have TBH app, just download the sbf file in update.zip.format. Boot into clockwork, clear data/cache, and for good measure clear dalvik (in advanced menu), then flash the update.zip.
Those steps are assuming your rooted and bootstrapped though. If your not you will have to SBF with RSDlite (which doesn't help you either because you don't have a pc)... so then you would have to get yourself a copy of a live (bootable off dvd) linux distribution like ubuntu or puppy linux, and install and configure SBF utility and use that to root.
