Have you tried to do it in webfig ? Not just in cli.

Is this US version?

Changelog of 7.15

*) lte - dropped support for R11e-LTE-US FOTA firmware update;

I tried both cli and UI.
Problem solved I went to System → RouterBoard and reset usb power after that modem is connected and allowed to upgrade without issues.

Thank you.

I’v tried it on: wAPR-2nD
and upgrade from:
EC200AEUHAR01A19M16_01.200.01.200
to
EC200AEUHAR01A26M16_01.200.01.200
but without success

process fails in both process (winbox and terminal)

I can confirm what kowalski78 said. The upgrade from A19 to A26 firmware is currently broken in wAPR-2nD devices.

Best to create ticket to support then.
