Cool! So then, is the uboot version on your device, which came from the factory with the older 1.1 factory firmware, different than the
Uboot version on your other devices, which came from the factory with the newer 1.2 firmware?
Does any jump of the factory firmware from version to version rewrite uboot with a newer version?
Is your uboot ubi aware or not? Or does that even matter with uboot?
I noticed when you ran your report on your device, it said no NAND blocks were bad. So I'm assuming the ubi and non-ubi firmware would both run fine on it - and would do so until a block failed in which case the non-ubi firmware would crash.
Interesting about the voltages.
Ted

PEBKAC.
Ben was trying to tell me what was wrong, but I was deaf. There *IS* a ubi version:
https://downloads.openwrt.org/releases/24.10.0-rc4/targets/mediatek/mt7622/openwrt-24.10.0-rc4-mediatek-mt7622-linksys_e8450-ubi-squashfs-sysupgrade.itb
which somehow I was unable to see. All I could see was:
https://downloads.openwrt.org/releases/24.10.0-rc4/targets/mediatek/mt7622/openwrt-24.10.0-rc4-mediatek-mt7622-linksys_e8450-squashfs-sysupgrade.bin
I clearly can't read while chewing gum. Also, the kernel panic, had I looked closer, would have been a clue. It was failing to mount /dev/mtdblock10, which shouldn't exist on the ubi firmware.
However, there *does* seem to be some persistent reboot problem.

Which is weird because BL2 has the same sha256sum as a clearly working device. Still looking into that.

The room is in the basement of the PSU Engineering Building (also connected underground to the Fourth Avenue Building, or FAB). Enter through the Engineering Building. The outside door will be locked, but there should be someone present at the entrance to let you in starting at 6:40pm until 7pm. There will be a sign on the door with a phone number you can SMS if there isn't someone there to let you in immediately.
