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

  • 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.

  • Hi,

    i got two more APX120 with a red LED bug.

    tried a few other methods, this one works fine 

    1. get into uboot emergency console, change bootdelay, save, reboot
    2. enter uboot console, set all env variables, save, reboot, enter uboot
    3. erase nand chip, tftpboot old APX.v11.0.019-2.uimage, connect APX120 to a XG 19.5.3
    4. boot from memory, APX120 will boot and register with XG 19.5.3, enable APX and wait for final F/W upgrade to 11.0.021-1

    No need to get root access

    But with 11.0.019-2 i had a root access without any failsafe method.

  • Hello Juergen, 

    Can you tell me where you find APX.v11.0.019-2.uimage? Or if you have it, can you provide link to download?

  • Hi Juergen,

    Managed to find the Image (inside the Pattern Update tar). I could link the APX with the Firewall but after reboot I get an error - Volume kernel not found! and I'm back on the uboot console.

    Do you have any suggestion?

  • Hello Juergen,


    Can you post all the env variables that need to be set? I think I made some mistake there...

  • Hi,

    this is the fw_printenv from OpenWRT (root shell from APX120).

    setenv BASEMAC 7C:5A:1C:XX:XX:XX
    setenv SID P3200XXXXXXXXXX
    setenv baudrate 115200
    setenv bootargs mtdparts=spi0.1:0x8000000(rootfs) ubi.mtd=rootfs loglevel=1
    setenv bootcmd apx_check_reset_button\;run ubiboot\;run ubiboot_backup\;reset
    setenv bootdelay 10
    setenv ethact eth0
    setenv flash_type 0
    setenv ipaddr192.168.1.1

  • Thanks!! Managed to fix one APX, now lets try with the second one!

  •  

    Hi,
    can you tell me where to get the APX.v11.0.019-2.uimage ? All pattern files I found only include the newest version 11.0.021...
    Thanks Jan
