Getting errors when installing aosp-8.1-p4wifi.zip to update tablet GT-P7510

[Android Central Question]

Recovery install says
E: unknown command [log]
E: Error executing updater binary in zip '/sdcard/aosp8.1-pwfi.zip'
Error flashing zip.....

What does that mean? Is the file just bad? or have I missed a step?

Is this OTA update or you manually doing it ?
