The IT Department @infosec.pub activistPnk @slrpnk.net SSD forced itself into read-only mode -- how can this be reversed?

The background is here. In short, an SSD with the “Apacer” brand froze itself into read-only mode, presumably due to reaching a point of poor reliability.
The data on the drive is useless. It was part way through installing linux when it happened. I would like to reverse that switch to make one last write operation (to write a live linux distro), which thereafter can be read-only.
I have heard some speculation that the manufacturer uses password to impose read-only mode. If true, then the password would be in the drive’s firmware. Does anyone know what Apacer uses for this password?

The IT Department @infosec.pub diyrebel @lemmy.dbzer0.com Help- hacking is my only option; need to talk to a washing machine via serial TTL to reverse self-destruct booby-trap

My broken 15 y/o w/m has a serial port tracing to an atmega32L chip. I have a USB to TTL adapter which is set for 5v (as opposed to 3.3v) using a jumper. The TX, RX pins are connected to the RX, TX pins of the w/m, respectively. The power supply pins (0v & 5v) are left disconnected.
I ran
minicom -D /dev/ttyUSB0 -b 9600on the PC with the w/m powered off. Minicom seems to default to an “8,N,1” configuration. When I power on the w/m, minicom flashes a popup saying something like “no connection to /dev/ttyUSB0”. This is a bit bizarre because if powering the w/m triggers that popup, obviously there is a connection of some kind.I do not have the service manual for the Beko WMD 26125 T and the
