Recently I bought the Omada ER605 v2 and saw it supported OpenWRT so I followed the guide and it went perfectly, no hiccups whatsoever, however I have been noticing that my router will randomly crash completely, ssh stops working luci dhcp you name it. So I would like to restore the firmware, I took a backup as the guide said using the script and have the backup files but everywhere says you need console access by soldering to the board, I have no experience let alone tools to do this and was wondering if there is any other way to do it, maybe someone made a script or a command. I've tried dding to the partition which seemed to work then I used recovery mode to reflash the stock rom but after it got to 100 percent it just rebooted back to OpenWRT. I also tried ubiformat which didnt work because the partition was busy (/dev/mtd3)
If anyone knows how to revert back without soldering to the console on the board I would really appreciate it as it is quite unstable and OpenWRT just isn't for me.
