OK, I see there is no boot loader file provieded as part of the M4350 Firmware Version 14.0.9.10 ZIP archive.

...so the embedded Web UI does refuse the upload there?
Technically, there is an alternate way for pushing the firmware image:
Enable the TFTP Server on the switch via Web UI:

Admited, this feels like a little bit tough step, after the signature verification indication.
I would like to hear a confirmation from NTGR LaurentMa (yes, he does push us towards to the free Netgear Engage, certainly a good choice IMHO) and JulienR before going the hard way - as this isn't my environment, not my devices - and I'm not a NTGR rep here.

Difficult, since NTGR does not supply any popular checksum variant. Or have I missed something?
