Is this why I saw U-Boot Console say that "ubi" wasn't a recognized command?
My RT3200 bricked on the 1.1.0 installer, should I have used the first set of commands? (I didn't, I used the second set of commands, but it still seemed to work out in the end somehow.)
From the bottom of https://openwrt.org/toh/linksys/e8450#recovery_from_openwrt_kiss_of_death_okd:
Did not run the v1.1.1 UBI installer (e.g. anyone on OpenWrt 23.05.x or below, or older snapshots):
mtd read fip $loadaddr 0x0 0x140000 && mtd write fip $loadaddr 0x0 0x140000
Ran the v1.1.1 UBI installer (e.g. running recent snapshot builds. You'd know if you did it!)
ubi remove rootfs_data ; ubi read $loadaddr fip && ubi write $loadaddr fip $filesize
