You will need cfe, nvram1 and nvram2 which corresponds to mtd0, mtd1 and mtd2.
I think your nvram is corrupt or the firmware flash damaged. First try flashing nvram and your cfe has no issues. If that doesn't work, I'm pretty sure that your flash chip is toast.
I've uploaded mtd0,mtd1 and mtd2 here: https://www.dropbox.com/sh/agmhwz107bnu5u6/AAB-78KkBVfMbk7q7nXnSrQHa?dl=0
mtd3 has firmware copy 1
mtd6 has firmware copy 2
You can flash both copies using:
flash -noheader 192.168.1.10:/openwrt.trx nflash0.trx
flash -noheader 192.168.1.10:/openwrt.trx nflash0.trx2
