If you watch my video, I show you EXACTLY where the /boot folder is.
Yup, it's just where you said it would be. Here is a little update, after going in and deleting the update-uimage(scary process) not ulmage-update(this would probably brick the TouchPad), I found out that one has to run CWM, install from SD card again to get TWRP to work. Now that I have seen TWRP, here is a new topic for your next video, "Using all the features of TWRP." Good luck!
P.S Maybe a short tutorial on how to delete "update-uimage" from the boot directory for those folks that find TWRP will not run after installing. I've also heard that some people trying to install it are getting an out of space message too. Removing update-uimage is apparently the fix for that. Not that there will be any more updates for WebOS, but if there were, there might not be enough room in that directory or partition for the new update-uimage file that they say the updating process creates. I suppose once one gets comfortable with TWRP, deleting CWM might free up the necessary room.
