Flash NVME not working

Hi all,

I managed to installe the customized Radxa os for 5c in the uSD.
I added the hat for an NVME SSD; i’m trying to flash the Nvme directly from the “downloads folder” running the command to uncompress and then dd into the memory as shown in the wiki:
sudo xzcat /home/radxa/rock-5c_debian_bullseye_kde_b2.img.xz | dd of=/dev/nvme0n1 bs=1M status=progress

but when i try to uncompress this file with the command sxzcat I get an error
compressed data is corrupt

i’m wondering, is there an alternative way to uncompress this file or flash it into the SSD memory?
OR Am i doing something wrong?

Thanks
