Tiny PXE loads the temporary image all fine, Luci is reachable from port 2 via default gateway. Going system and uploading sysupgrade.bin either gets stuck on verifying image or no related RPC reply.
Repeating the same proccess with 18.06.08 results in either stuck on firmware upload image at 100% or corrupt luci
edit: restoring to stock firmware with netinstall and attempting again does not help
What could be the problem?
