Thank you for reply.
The Zyxel support sent you the Module Version, because you have requested it?
There is no download option on the Zyxel homepage for this version.
Yes, I requested that specific version from Zyxel EU (EMEA) support because the release notes for the latest firmware (v.04) of the router (LTE5398-M904) listed the LTE module firmware version EG18EAPAR01A12M4G.
I asked to include that version on the official download page, but they told me that it depends on the parent company and they have no influence on it.
I hope Quectel can help by sending me the DFOTA update from v.12 to v.13 (and from v.13 to v.12)
I’m currently on the version EG18EAPAR01A13M4G.
I would need the DFOTA to downgrade from V13 to V12 or from V13 to V8.
I also have the downgrade version from V13 to V8, but it does not work. I can not downgrade the module.
@Rcatech Hello!
Is a pleasure to guide you to the right person that domain firmware things; is @herbert.pan-Q
He is here in the business days, during business hours, quite often.
Do you have the latest firmware updater tools and drivers? They are quite important for a proper, and “peace of mind” successfully update process.
If you want, I can share with you my drivers and tools, even my device being a EP06-E, drivers and tools are mostly “commonly shared” by the “E” devices…
If you need further assistance, you can contact the field engineer @lyman-Q or check out the Quectel moderators or the support team, like @Raphael-Q and many more. Alternatively and furthermore, you’re always welcome to send an email to: support@quectel.com and address your questions and issues… I can guarantee you that you will receive a proper assistance with a polite and great communication over there.
I hope that all this can help you for a while. Please don’t use a different firmware on your device, it can damage it seriously - tools and drivers are common or shared, but never firmwares.
@Rcatech I forgot to mention @tabor.tang-Q, that is from support team, and handled a similar case, like yours…
I apologise for the inconvenient.
Usually, all tools, drivers and firmwares are sent to the email that you used to create your account here in the forum. Sometimes is good to check your spam folders…
