I have Linksys EA4500 that runs OpenWrt Chaos Calmer (CC) without sysupgrade support (candy router flash layout).
My understanding that to move forward with Linksys EA4500 I have to boot the device using the stock firmware first and perform a regular firmware update using OpenWRT DD or LEDE factory.bin image.
Unfortunately my device has CC in both primary and backup partitions, so in any case my device boots with CC.
- Is there any way to upgrade my box to DD or LEDE without serial connection?
- My understanding that LEDE firmware is expecting a factory-like MTD flash layout. Should I restore the layout somehow? Can it be done without serial connection?
