I think I may have corrupted my CFE. I would be glad for someone with RT-AC68U and E1 revision to pull out their CFE.

If you have other revision of the router you can also post your CFE. We can try making an archive of different CFE's.

Here's the instruction (it takes only 5 minutes to do, so I would be glad for help). The whole procedure is unharmful.

You will need Putty and WinSCP :

Download PuTTY:
https://www.chiark.greenend.org.uk/~sgtatham/putty/latest.html

Download WinSCP:
https://winscp.net/eng/download.php

1. In the router web GUI enable SSH in "Administration" - "System" tab.
2. Open Putty SSH connection on port 22 (use your routers LAN IP address to connect)
3. Open WinSCP and connect them to your router using its Lan IP address), In WinSCP select SCP as protocol.
4. In putty type: cat /dev/mtd0 > original_cfe.bin
4. In WinSCP you should be in the /home/root or /root directory hit the refresh icon on right side to see original_cfe.bin.
5. Copy original_cfe.bin form router to your computer by dragging from the right window to your computer in the left window.
6. Please paste original_cfe.bin here on the forum
7. Disable SSH in "Administration" - "System" tab if you had it disabled.

They are provided in the firmware. You will have to figure out which one. Just extract the RT-AC68U_3.0.0.4_386_43129-g60defb2.trx with 7-Zip.

You might want to try this first! The bootloader on Asus is fairly durable, it was stolen from Openwrt code.

no they arent. they are different from the installed versions and contain different parameters. we need always the real ones from the device.

The CFE contains hardcoded device specific MACs for the interfaces, 3 total.

I can share my CFE if needed with mangled MAC addresses needed to be replaced with original device specific MACs for the target device before flashing.
