If true, then this will debunk the theory that issue started from the v1.0.3 installer. Did you confirm that your router failed to load bl2 via serial console?
Maybe the issue is with converting flash to UBI over MTD instead of squashfs? From what I read, UBIFS maintains indexes to speed up mounting. Could it be that the UBIFS index has been corrupted during a power trip?
For those facing OKD, do you constantly write into your router’s flash storage, like log files or stats history?
Has anyone been running their RT3200/E8450 using squashfs instead of UBI and also encountered the dreaded OKD?
