Recently I was reading that flash can go bad (lose data) after like 10 years or so and I started poking around with the mtd devices and backing up the router. My understanding is granted you can use the original install files and the backup, maybe you can restore any changes I made myself? I usually install the usb storage, samba server, and stuff for yt-dlp.
MY QUESTION IS THIS THOUGH
Would it be right to say, that like the tftp update function is in the SOC somehow, or does it rely on part of the flash chip being coded as it? When we update the flash, is it typical for parts of the flash to not be altered?
