The back button on my X2 is failing and I'm unable to modify the system/use/keylayout/tegra-kbc.kl file to re-map the SEARCH button to the BACK. I didn't have a problem with my first X2 when the back button failed. The only difference between this X2 and my last one is that I'm now running Eclipse. Looking at file permissions from Astro it is only "r". From ES Explorer, it is "rw - r - r" and I am unable to change them. The basic messages I get when trying to save the file after modifying is that I don't have permission.
What's the deal?
