Looks like your root file system is damaged as well. I doubt the one from Ph3 will work for you - someone would have to dump the whole NAND on a working device in order to fix such damage.[ 1.370000] UBI error: ubi_io_read: error -74 while reading 512 bytes from PEB 35:2048, read 512 bytes

What happened to that camera? was it left on direct sunlight for a year?
It would seem the whole NAND got de-programmed.
