One partition is set as active and boots. If boot fails three times, than the “other” partition is set as active and booted, assuming it is still safe. A bootcounter (stored in the partiton S_ENV) is used for this purpose. The bootcounter has a flaw that prevents direct install of OpenWrt. Use this procedure to bypass: Use the Linksys GUI to flash the Linksys OEM firmware. The device will now boot Linksys GUI from partition B. Flash OpenWrt squashfs-factory image with Linksys GUI, it will be installed on partition A and will boot. You will be able to boot OpenWrt three times from partition A, until the bootcounter flaw set back partition B as bootable (with Linksys GUI). To prevent this, add this code to etc/rc.local /rom/sbin/mtd unlock s_env /rom/sbin/mtd erase s_env exit 0 This code erases the S_ENV partition that contains the bootcounter. Information from this forum thread https://forum.openwrt.org/t/can-not-install-openwrt-on-linksys-ea7300-v2/85421/11 Upgrading OpenWrt The advice for other Linksys dual partition routers, is to revert to booting Linksys stock firmware from the other partition (A). Then install the new OpenWrt squashfs-factory image using Linksys GUI, as described earlier in this wiki page. If you were to use OpenWrt to install the new squashfs-sysupgrade, there is a risk of overwriting the Linksys stock firmware on the other partition with other Linksys routers such as the earlier EA6350 v3 and EA8300. It is not known at this time whether this behaviour applies to the EA6350 v4. Debricking The EA6350 v4 is a typical dual partition device. The Linksys firmware is copied to both partitions at the factory. At the time of writing, it is recommended to never overwrite both partitions with non-Linksys firmware images, if you wish to keep the option to return to using Linksys firmware in the future. Reverting to factory firmware Hard-reset the router three times to force it to boot from 'B.' This is where the stock firmware resides. To remove any traces of OpenWrt from your router simply flash the OEM image at this point. Failsafe mode → failsafe_and_factory_reset Basic configuration After flashing, proceed with Basic configuration: Set up your Internet connection, configure wireless, configure USB port, etc. Specific configuration Please fill in real values for this device, then remove the EXAMPLEs and the WRAP that encloses this text.
