Just flashing the new main/master snapshot decreases the OKD risk somewhat, as it contains the fip scrubbing feature, which causes UBI filesystem to react to too many bitflips and read/write a faulting flash block to another. That doesn't remove the risk of OKD, but may decrease it.
Like grauerfucsh says, there is no need to run a new full installer from Daniel, when he publishes one.
The only needed steps for a main/master snapshot with "fip in UBI" layout are:
- normally flash the new sysupgrade to activate the fip scrubbing feature in future.
- note: to be able to opkg install the current kmod-mtd-rw, you will need to first sysupgrade to the current snapshot image, and only then install kmod-mtd-rw and write the bl2
- you need to opkg install the kmod-mtd-rw (or include it in your own firmware image) and then separately load it during runtime with "insmod" like I did.
- you can download the new bl2 (preloader.bin: http://downloads.openwrt.org/snapshots/targets/mediatek/mt7622/openwrt-mediatek-mt7622-linksys_e8450-ubi-preloader.bin ) and mtd write it from a live OpenWrt SSH console, like I did above in Belkin RT3200/Linksys E8450 WiFi AX discussion - #5702 by hnyman. At your own risk...
