Hello,
i'm trying to flash mfw-nr+_nrf91x1_2.0.0.zip on a thingy91 x. it doesnt work via nrfutil
nrfutil device program --firmwaremfw-nr+_nrf91x1_2.0.0.zip
THINGY91X_13A2EC8A4FC: Failed to read file `manifest.json` from extracted MCUBoot multi-image ZIP archive: specified file not found in archive
it also doesnt work via jlink. presumably the jlink header is actually connected to the nrf53
nrfutil 91 modem-firmware-upgrade --firmware ~/Downloads/mfw-nr+_nrf91x1_2.0.0.zip -
