How could I fix this or is something damaged?

Styx

I have a model GNAWTY E4F-G3V-S2B-Q3V Chromebook and when I powered it on one day it said "Chrome OS is damaged or missing." So I did what anyone else would do and tried to shutdown, hold ESC and Refresh and then press power. Still said Chrome OS is missing or damaged. So I tried to use a USB with more than 8 gb and it stop on one step and says an unexpeted error has occurred. When pressing TAB the recovery reason is o2ox recovery button pressed or something like that. I have tried many things but don't know how to fix it.

It looks like the Gnawty codename (sounds like one of the marketing people was being a little naughty when they came up with it) was for the C730 model line (C730, C730E and C735), though it might also include the CB3-111/CB3-131 models as well. You should have a sticker that tells you which one it is. I believe all of those used an eMMC chip for their storage, which is soldered to the motherboard. If the chip is failing or failed you would get your symptoms, because attempts to write to the chip would fail. You could do more searching on the Google support pages to see what that error code is caused by, but my guess is that it's generated by the failed write. There is not a lot that can be done for you, unless you know of someone with the soldering skills needed to remove and replace surface mounted chips...
