For the unknow characters, seems to be some chinese characters (from journalctl):

trying with Sandbox app I found this error:

throw new IllegalStateException(K_SUFFIX + " expected at the end of " + section);

where K_SUFFIX is "Kg", but this device has a section "Ka".

I know zero to none of dfu, what problems could cause a section not ending on Kg? Can this code be improved to support those sections?
