The EVO 840 (predecessor of your model) provides a SAFE mode where you can also do a firmware update through SATA.
(The third method is theoretically through the UART interface, but it's too unstable to be usable)
Additionally we developed a firmware update method through JTAG.
You might be interested in trying my SSD diagnostic tool
https://github.com/thesourcerer8/SSDdiag , it has not been ported to EVO850 yet, but it might give some insight anyway, since most of the hardware in the controller is still the same.
I'm having:
SAMSUNG SSD 840 EVO 1TB, still able to boot in SAFE MODE with FIRMWARE: UNKNOWN
SAMSUNG SSD 840 EVO 120GB, in good standing with FIRMWARE: EXT0DB6Q
SAMSUNG SSD 840 EVO 120GB, EXT0DB6Q, I was able to upgrade from EXT0BB6Q to EXT0DB6Q by this command in REGULAR MODE
Code:
hdparm --yes-i-know-what-i-am-doing --please-destroy-my-drive --fwdownload EXT0DB6Q /dev/sda
so, the process is kind of working to upgrade the firmware, while I'm trying to move from EXT0DB6Q to EXT0BB6Q back it gives me this kind of error:
Code:
hdparm --yes-i-know-what-i-am-doing --please-destroy-my-drive --fwdownload EXT0BB6Q /dev/sda
/dev/sda:
fwdownload: xfer_mode=3 min=1 max=2048 size=512
