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... Erasing Nand... Attempt to erase non page aligned data
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.
Tried four times, and finally!
But I got this:
Starting kernel ... Press the [f] key and hit [enter] to enter failsafe mode Press the [1], [2], [3] or [4] key and hit [enter] to select the debug level f - failsafe - /etc/preinit: line 1: telnetd: not found (none) login: Please reboot system when done with failsafe network logins
and then
Starting kernel ... Press the [f] key and hit [enter] to enter failsafe mode Press the [1], [2], [3] or [4] key and hit [enter] to select the debug level fPlease press Enter to activate this console. Warning: Bad CRC, using default environment (none) login: Booting. (Version: 11.0.021-1) Checking The AP model Starting network configuration for ethernet interface over DHCP. Cloud certificate validation pending. dnsserver entries are missing [
This model (APX120) really needs more QA!
There is no failsafe in the new firmware images.
you need to enter uboot cli and erase the flash, load an old kernel with tftp. Boot into failsafe and update with shell script.
Could you share a link to an old kernel image? I got the image from my XG firewall and it seems to be the latest version.
Thanks!
Use this image https://d2apih4urmzzdu.cloudfront.net/v2.1.1-1/APX.uimage
TFTP boot with this in Uboot, then when it shows the failsafe prompt keep pressing enter until you get root.
Thanks!
Finally get into root.
Thanks!
Finally get into root.
Hi,
i got two more APX120 with a red LED bug.
tried a few other methods, this one works fine
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).

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