acer c7 can't read or write

[Johnny Bazookatone]

So I managed to flash my chromebook with a Coreboot Seabios payload by
following this tutorial

I managed to install Ubuntu 12.04 using my flash drive.... and became very
dissapointed that my touchpad didn't work.. So I tried to recompile stock
firmware and tried to use flashrom within Ubuntu to go back...but I can't
seem to get it to write... So am I going to have to buy a bus pirate to
reflash??
