Hi,
Are you sure that the you were previously using a v2 firmware file? v2 was
not supported until recently and loading it with the v1 loader would just
result in garbage being written to the device.
The patch[1] that adds support for v2 is pretty standalone and you should be
able to backport it to v3.18.
