Since you said adb sideload I guess you run stock 4.4.2 and thus tried to flash a package with stock recovery (like when rooting). Luckily for you this does not work with unsigned packages. Cause if it had you would have ended up with no bootable recovery at all because loki is patched in the boot loader.
There is no custom recovery for 4.4.2 yet
only workarounds with old boot loaders and patched kernels.
The forum is full of people having all kinds of issues with those.
