Trying to unbrick my APX120

I am using the instructions to unbrick my APX120 from this post, but I have run into issues below:

community.sophos.com/.../unbrick-apx120-break-bootdelay-0-recover-apx120

I can't seem to save the environment variables. When I run the "saveenv"

It says:

Saving Environment to NAND...
Erasing Nand...
Attempt to erase non page aligned data

  • I have exactly the same error

    (APX120) # saveenv
    Saving Environment to NAND...

    This is the system initialization prompts (short U26 pin 8)

  • You need to retry to break autoboot.
    sometimes you need a few attemps.

    i prefer to read the nor with in circuit flash.

    if you can save the environment you must rebuild all env vars before loading the image file.

  • I second this. I had to retry it again a few times until I was able to save the environment variables.
