Only issue I sometimes had with updates is limited memory (on the lowend hap lite devices). Often a reboot before upgrade download was enough to solve that. But the standard upgrade procedure is to put the new firmware image in the filesystem root (scp, update button via UI, etc) and reboot the device.
