Sorry Polanskiman. I was confused by your link https://www.synology.com/en-global/know ... using_a_PC. I thought it's the same as your write up. I am so happy that I manage to recover the data. I am new with xpenology and try to solve my first brick xpenolgy. Been googling and reading a lot of thread. Since I already successfully copy the data, now I am trying to fix the xpenology by downgrading the DSM. I will try to mount the system partition from your tutorial. Sorry for the confusion.
