[Electronics] How to backup flash from TPLINK WR703N

This page talks about how to backup entire flash content on your TP-Link router WR703N, so a restore can be done if something messed up.

If you want to backup u-boot only:

cat /dev/mtd0 > /tmp/backup_u-boot.bin

To backup ART partition only:

cat /dev/mtd4 > /tmp/backup_art.bin

To backup firmware with settings:

cat /dev/mtd5 > /tmp/backup_firmware.bin

To backup full flash:

cat /dev/mtd0 > /tmp/backup_fullflash.bin
cat /dev/mtd5 >> /tmp/backup_fullflash.bin
cat /dev/mtd4 >> /tmp/backup_fullflash.bin

now copy bin file(s) from tmp dir on router in your computer via WinSCP.
