How to install RUU

[andreiv3103]

Hello
I would like to return my HTC one mini to factory firmware. After much searching, I found and downloaded this:
https://www.androidfilehost.com/?w=files&flid=29622
PO58IMG_M4_UL_K44_SENSE60_MR_HTC_Europe_4.14.401.2_Radio_1.28.40e.00.24_10.z19.40.1304L_release_450912_combined_signed.zip

I checked my device version:

$ Fastboot getvar version-main
version-main: 4.14.401.2
finished. total time: 0.006s

I tried this:

fastboot oem rebootRUU
fastboot flash zip firmware.zip
target reported max download size of 800227328 bytes
Invalid sparse file format at header magi
error: write_sparse_skip_chunk: don't care size 300873309 is not a multiple of the block size 4096

The bootloader is relocked.

What could be the problem?

P.S. I cannot open the zip file in Windows. It says it is invalid. Could be corrupt?

Hmm... I think that a Relocked bootloader is the problem. By the way did you try flashing the RUU trough TWRP?
