[nickpar]

Hello there,

i bought this aircard

https://www.amazon.de/gp/product/B01FUZE5H8/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1

and part number reads this

AC810S-1TSNDS

I am not sure how is this different to AC810-100EUS ?

AC810S-1TSNDS is a model branded by a norvegian ISP : Telia

Here is their documentation

Seems to be similar or identical to the 100EUS, BUT:

AFAIK , there is no way to update it, it's stucked to a very old firmware , NTG9X40C_11.14.08.16 , 

and impossible to update (as it's an OTA update that must be done through Telia ISP , which is not possible since you don't belong to this ISP).

The only solution seems to take a fly to Oslo, buy a prepaid card, update it, and come back.

this was my guess but i was wondering if it is possible to update from file or even mess with the device and provide a firmware for EUS

Is it technically possible ? I guess so , if you have access to the firmware file from netgear developper or else, and know enough to connect to telnet to it on port and run the AT!BOOTHOLD , with the right qtools.
The harder is to get the firware file I suppose, as the last released file from netgear were for the AC785.

But it is way out of my league, unfortunately.  plus, I don't speak russian.
