I recently purchased an S1300, which comes with the very old OpenWRT Chaos Calmer. I want to upgrade to the latest stock OpenWRT so I can have confidence in the security of the device. When I try to do the upgrade via sysupgrade or the Luci UI it does not work. When the S1300 reboots, it is still running the same Chaos Calmer.
The first thing I tried was to use the procedure recommended by the OpenWRT website:
-
I downloaded openwrt-21.02.0-rc4-ipq40xx-generic-glinet_gl-s1300-squashfs-sysupgrade.bin from the OpenWRT website and copied it to the S1300 using scp. I put it into the /tmp/ directory on the S1300.
-
I logged into the S1300 with ssh and ran this command:
sysupgrade -v /tmp/openwrt-21.02.0-rc4-ipq40xx-generic-glinet_gl-s1300-squashfs-sysupgrade.bin
I got some output regarding the config being backed up, then the wifi connection dropped. I waited 5 minutes then sshed back into the S1300. It was still running Chaos Calmer. I tried powering it off/on but still it was running Chaos Calmer.
I also tried using the luci web UI to do the upgrade, but again the result was the S1300 still running Chaos Calmer.
I then read in another topic on this forum that suggested installing the s1300-factory-to-openwrt.img firmware upgrade first. So I installed that firmware upgrade (the version for openwrt-19.07.7) via the U-Boot web user interface. Then I tried the sysupgrade procedure again. Still the S1300 is running Chaos Calmer.
Can someone please advise how I can upgrade my S1300 to OpenWRT 21.02.0-rc4?
