Think I bricked my EdgeRouter-x

Installing and Using OpenWrt
1

Hi, I used this howto to install openwork on my Edgerouter-x. Factory reset with the latest stock firmware.
Uploaded the initramfs, rebooted, scp'ed the kernel.bin and ran sys upgrade; router does not respond on 192.168.1.1 even after 10 minutes al tested on all ports.
I did run sys upgrade with the force method, as alle kernel images I've tried gave "image check failed".

Is there any way to recover?

cheers, slek.

Official install instructions: https://openwrt.org/toh/ubiquiti/edgerouter_x_er-x_ka

It is not right to use a kernel.bin image. That would be an incomplete installation as there is no rootfs. Sysupgrade should be run with the squashfs-sysupgrade.bin image. If you use a matching version there will be no need for the -F flag, but -n should always be used to be sure that fresh config files are generated.

Anyway from here you have the choice of factory TFTP recovery, or serial control of the bootloader to manually TFTP and boot.

Check if factory TFTP is supported by holding down the reset button while plugging the power in. After about 30 seconds of holding the button, a TFTP capable bootloader will start blinking the port lights back and forth. If yours does that, obtain the special recovery image from Ubiquiti and TFTP push it to the router when the lights start blinking. (you only have about 1 minute after entering recovery mode to do that, after that the TFTP server shuts down even though the lights keep blinking indefinitely)

Ah, Nice.. Managed to recover bt tftp. Just upgraded to latest ubiquity version. I'll try the official install method. Thanks much.

EDIT: acc to google I should install Luci with opkg, but there is also no opkg installed

Now successfully did the Sysupgrade with "-n" and after reboot, I can only ssh - no web. netstat too shows only ssh listening.
Must be missing something. So did the factory image via de stock web upload.
file: openwrt-ramips-mt7621-ubnt_edgerouter-x-initramfs-factory.tar

After reboot copied the file squashfs file and sysupgraded, no warnings and device rebooted:
file: openwrt-ramips-mt7621-ubnt_edgerouter-x-squashfs-sysupgrade.bin

According to the official manual (step 4), I should be able to configure via web, but no web.

The files used are 22.0 from here:

cheers.

All good now. Used a stripped down version somehow.
