## Flash OpenWRT from OpenWRT (!)
|
|
|
|
|
|
|
|
|
|
Copy the firmware in router's `/tmp`.
|
|
|
|
|
Why `/tmp`? Your router has more volatile storage than persistent one, moreover you will overwrite the persistent storage.
|
|
|
|
|
So, copy the firmware in `/tmp`!
|
|
|
|
|
Next, we will use the `sysupgrade` command. `-v` is verbose, `-n` ask openwrt to erase configuration files (ie. ask for a factory reset).
|
|
|
|
|
|
|
|
|
|
```
|
|
|
|
|
sysupgrade -v -n /tmp/openwrt-ipq40xx-generic-compex_wpj428-squashfs-sysupgrade.bin
|
|
|
|
|
```
