Hopefully, this will be helpful.
I went ahead and removed the device. Upper half of the device basically fell apart!
Unfortunately, through one of the pad is damaged and the all important via seems to be ok, except for one. That pad, pin #3, the missing part appears to have a connection to inner layers, and potentially a partial through-hole.
To help you look, I put one black dot above Q3400 to indicate the same via.
