R11eL firmware upgrade

RouterOS General
1

I have an old firmware version v02.14 on the R11e-LTE-US in my LtAP mini.
Per the wiki, this board can only be updated trough FOTA.

I have my lte interface running, I can ping through it on the internet.
When I check for firmware upgrade, it’s telling me v05.04 is available.
However, as soon as I launch the firmware-upgrade upgrade=yes, my lte interface shutdown, I have no connectivity anymore and the firmware is not updated. I have to restart the interface to get connectivity again.

How can I get the firmware upgraded?

Last version is R11eL_v16.02.183961, where you have read v05.04?
Also v02.14??? The firmware vesrion is something like R11eL_v16.02.183961
If you have v02.04 or other, is not one R11e-LTE-US module

It’s a LtAP mini, so the card is integrated.

Hi, did you finally make it ? I also have a LtAP mini LTE-US which I was not able to update the modem firmware to v05.04.193841 for a long time.
