The EA6350v3 is a dual firmware device. ie. There are 2 partitions and Linksys firmware is copied to both partitions at the factory. When you install/update the Linksys firmware, or install/update OpenWrt, the new firmware is always written to the other partition. Upon restarting the EA6350v3, it will subsequently try to boot from the newly installed firmware image from other partition.
If the device fails to boot after install or upgrade, whilst the unit is turned on:
Wait 15 seconds
Switch Off and Wait 10 seconds
Repeat steps 1 to 3, 3 times then go to 5.
U-boot will switch back to the last working firmware - you should be able to access your router on LAN.
The above method can be used to toggle between the two firmwares.
Warning: If you install/update OpenWrt more than once, both partitions will be overwritten with OpenWrt firmwares, and you won't be able to revert back to Linksys OEM firmware using above method.
Generic u-boot tftp client method to restore firmware to EA6350v3 does NOT appear to work when tested with tftpd64 client and Linksys Utility.
: EA6350v3 is very similar to EA8300, and using a serial connection and tftp server may work. The OEM Boot log shown below may be incomplete. ie. missing boot log from Uboot. Refer to the 'TFTP Recovery' section for the EA8300
Use the generic recovery using the tftp client method to flash the “civic.img”. Also you can strip-and-pad the original image and use the generic “mtd” method by flashing over the “kernel” partition.
Just be careful to flash in the partition that the device is currently booted.
