I upgraded an old openwrt on vocore to lede-17.01.4-ramips-rt305x-vocore-8M-squashfs-sysupgrade.bin, but then discovered I have the right chip for lede-17.01.4-ramips-rt305x-vocore-16M-squashfs-sysupgrade.bin.
In the web interface, however, attempting to upgrade yields the messge "The uploaded image file does not contain a supported format. Make sure that you choose the generic image format for your platform." The sha256sum is correct, how to proceed?
Thanks,
Jim
