upgrading firmware flex200hp

PrevDiaImm Posts: 1

i'm currently on "V1.10(ABXE.1)ITS-24WK05-M3737" firmware version,

If i check for cloud firmware it result that "uOS1.10 Patch1" is available for download; but here on zyxel is available the "v1.20" firmware version.

I have to install first the patch and then the 1.20 ? or i should download the 1.20 from the library and upload it to my device from local?

with regards
