<![CDATA[Problem starting kernel, did I brick my board]]>I was trying to get my board back to using the onion2lte OS after I got it to the most recent OpenWRT OS. I found the image file for the omega2lte OS, and I put it on my board. Because I had trouble using scp, I ended up putting it on the board by making a github repository and downloading that with git clone. Because of that, it was not in my tmp folder, which I think might be the cause of my problem. I ran sysupgrade on it, and when it failed the image check I used the -F tag to force it. Now, when it boots, it will briefly show the OnionOS banner, then it says the following:

And it will repeat some variation of that last line for about a minute before it reboots and starts the process again. I can only connect to my board via serial on Putty, and at no point in this process can I put commands on that terminal. What I'm wondering is did I brick this board, or is there some way I can fix it over serial?

I found the image file for the omega2lte OS, and I put it on my board. Because I had trouble using scp, I ended up putting it on the board by making a github repository and downloading that with git clone. Because of that, it was not in my tmp folder, which I think might be the cause of my problem. I ran sysupgrade on it, and when it failed the image check I used the -F tag to force it. Now, when it boots, it will briefly show the OnionOS banner, then it says the following:

And it will repeat some variation of that last line for about a minute before it reboots and starts the process again. I can only connect to my board via serial on Putty, and at no point in this process can I put commands on that terminal. What I'm wondering is did I brick this board, or is there some way I can fix it over serial?

I wonder if you mucked up the firmware with your "solution" to not being unable to use scp. Did you see my reply to that post?

The LTE is basically an Omega2S+ with the LTE stuff added in, so for future reference you can always use the Omega2+ firmware images and then add in the LTE packages separately.

Have you tried a factory reset? If so, what were the results?

Next step I would try is to reflash the device form USB, the instructions are here:

USB device can be fussy so you may have to try from more than one USB device.
