Firmware Update failing verification

Have spotted the potential manual boot code update requirement from the release notes?

 

Known Firmware Issues:

• The boot code might not update automatically when upgrading to this firmware because the firmware size has increased.
  Workaround: Update the boot code manually, or upgrade to the same firmware version again.

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: 

 

System > Management > TFTP Server

 

...

 

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.

Verified checksum is good

 

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