Please an expert

Unfortunately i deleted EVERYTHING in my p8 max.. there are NO DATA and NO SYSTEM files.

There's only the mate s recovery that works.

I tried to flash a zip with the stock firmware inside but the recovery showed me "unable to mount '\system' " and "Zip file is corrupt!" in red.

In addiction, my pc can't even recognize my p8 max, but it shows a connected device called "CRR - L09" that is my phone.
It is shown as an MTP device because I DIDN'T ENABLE THE USB DEBUGGING on my phone.
Is has a folder "internal storage" in which i put my zip with the stock firmware to flash(i said it didn't work) and other 2 sub-folders that are "TWRP" and "obb". Just these two.

My HiSuite(the huawei tool) can't recognize of course my device
