Problem with re-flash android stock - HTC Desire 825 Questions & Answers

Hi there,
I have a small problem re-flashing android stock rom on my Desire 825 device.
I have found the stock rom. It is called 2PUKIMG_A56_UHL_M60_SENSE80GP_HTC_Europe_1.00.401.4_Radio_3.0.U205561.60412G_release_476327_signed_2_4.zip.
Everytime i try to flash it via fastboot with microSD card or with RUU it gives all kinds of strange zip header errors. I followed a tutorial from a site called (hardreset). I have S-ON it seems, but this shouldn't be a problem.
Device info from fastboot is:
Code:

How could i get over these problems and eventually install the official rom ?
