@freakqnc: I'm not trying to get into a peeing match, the main flaw I wanted to point out was that this guide does NOT include the use of this exact file: SPRecovery_ESE81.sbf. That file and any guide, thread, post, video, or link to it should have been removed from the internet over a year ago when Froyo was released as it still is the cause of much grief when people use it! The SPRecovery_ESE.81.sbf file includes a 2.1 kernel which is why you had the result you posted in #1859. So to say that you follwed this guide to a 't' in the same breath as mentioning SPRecovery_ESE81.sbf is simply incorrect.
MotoCache1's .sbf file contains no kernel and neither does his update.zip file. All his update.zip file contains is the 'su' and 'busybox' binaries and Superuser.apk with some scripts and the proper scripting within the updater-script file to install all of such. All one has to do is open it to see for themself what it contains.
