What you can try is to unpack the previous zip again, and skip straight to a Reboot (i.e., don't run ;log r).
Then try the hotfix via UYK again, or the bridge via mrpi after another reboot.
Logs will be useful, as always
.
EDIT: I'd also update MRPI like in
#2 instead of the mangled version I gave you later, just for good measure
.
