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 came across a few APX120 that had a faulty NAND chip, so maybe your APX has faulty one.
    Power cycle your APX and post the uboot log.

    You need to short SO/SIO1 for a fraction of a second in the right moment, the nand will not be available now.
    Try to set the bootdelay to 5s, power cycle the APX and enter uBoot.

  • Hello Juergen, I followed your method to break the boot loop and shorted S0/SI01. Then I could press any button to stopautoboot. At first time I wanted to ping my TFTP Server and had a hang. Second time and now every time I short the nand it hangs at "Net:" what to do now?

    *** Warning - readenv() failed, using default environment

    In:    serial
    Out:   serial
    Err:   serial
    machid: 8010100

    Net:

  • Yes, I need several tries to get the "hit any key to stop autoboot" message. No problem so far.

    it starts to load the default environment and stops loading at "Net" where normally should appear the MAC.

    It worked when I tried the first times but now I have a hang at "Net..." EVERY time. It is frustrating...

    I am using the DSD TECH SH-U09C5 Adapter set on 3.3V. Should not be the problem. As + wire is not connected, that should not play any role. I am using a power supply to power the AP. I already tried with Ethernet Cable connected and disconnected.

    Please read my comment at the end of this topic about the autoboot loop

    I saw your comment thanks. Unfortunately it hangs and wont get to that point where I can enter commands.

  • If you don´t glitch the NAND, where does the log stop/end?

  • If not glitched, it makes its known loop until "ERROR: can't get kernel image! resetting ..."  NAND is beeing initialized without problems..

    I am not at home a this moment. I will collect the detailed console output and post it here.

  • If glichting is not working, use a Pomona SOP8 IC Clip and read the flash with a very low voltage (2.6 - 2.7V) and slow timings.
    This will prevent the cpu from starting.

    Read the flash and change the bootdelay, this will give a uboot env. error, but easier than glitching,

  • Thank you for this advise. I think an IC Clip wont be enough? Will I also need an CH341A Adapter and Software AsProgrammer/NeoProgrammer? Is there a good guide how to edit NAND data using this stuff?

    This is shown when glitching NAND. It stucks at "NEt" and does not continue..

    resetting ...

  • You need a good programmer, that can read at low voltages and slow speed.
    One you read the chip you can edit the content and change the bootdelay.

    But the environment variables are no longer correct and must be reset.

  • Can you post all the env variables that need to be set? My APX120 would not connect to Sophos Cloud

  • Do you know programmer hardware you can recommend?

  • is use a REVELPROG-IS with a Pomona 5250 Clip
