So there is still no solution? I changed mine without keeping the board powered, cant log in anymore, or do anything else, time of course complete random, and ps4 support didnt do a s***, are we still stuck?
I may try the new ram site, and download more RAM to my Switch. Not sure if ddr3 is the right ram
for it tho. Edit- no it uses floppy Ram, just like @AncientBoi
