I bought a 4A 100M and a 4A Gigabit.
The gigabit version flashed openwrt without problem, but the 100M got these errors.
This may have something to do with the International Version.
Tried with both openwrt-ramips-mt76x8-xiaomi_mir4a-100m-squashfs-sysupgrade.bin and openwrt-19.07.0-ramips-mt76x8-xiaomi_mir4a-100m-squashfs-sysupgrade.bin.
