I've been trying to remove the Ubuntu ext3fs partition for a few hours now with no success. I first ran WebOS doctor and then used the directions here (gadgetXplorer: #webOS: How to remove EXT3FS partition) after WebOS doctor finished.
I successfully went through with the tutorial and then rebooted my Touchpad. To my surprise, the Linux penguin was still there and the amount of free space I had did not change! I then ran WebOS doctor again and the result was the same.
Does anyone know how to fully remove the Ubuntu partition and any traces of Ubuntu chroot?
