Hello. I'm new to this forum and I joined because I was searching the XDA forums for a way for me to play Modern Combat 2 on my Nexus 7.

To do this I decided to use the build.prop of a Nexus 4, because it has a Tegra 2 which the game supports, unlike the badass Tegra 3 quad core processor of
the 7.

So I replaced the original build.prop, making a backup of the stock. I rebooted, and it never responded since.

I have used the bootloader screen, but accessing the recovery program from that just said, "no command." In no manner was fast boot or any other of the options doing anything to help me.

I am unlocked and rooted obviously, and I would really like to not lose my music.

I believe I have TWRP but I have no honest idea how to get to it.

I would appreciate a way to retrieve my files and restore it, or even better revert it back to it's glorious rooted days with no loss of data. Thanks for the help!
