Good morning, I have an LTE5398-M904 purchased directly from the Zyxel website, with the ABQV .6 firmware regularly updated by me, and with the LTE 08 module firmware. I would like to update it via the router's website to the official version 12 which I believe I understood is the latest official Zyxel version. I read that at a certain point you have to remove the SIM card because it could cause problems (I wouldn't be able to update it manually in the slightest). It seems trivial but I can't find the 12 on the official Zyxel website, or rather on the download page of the website. I only found the ABQV.6 and not the LTE module firmware that I'm interested in. Could you kindly direct me where to download the latest official version? Thanks.
