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

Thanks to all for your help, only the following steps worked. I had to update to V 2.3.4- 5 (maybe because my XG is already on SFOS 20): get into uboot emergency console, change bootdelay, save, reboot…

Hello Juergen,

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

Hi,

how did you manage to get keyboard inputs in putty ? are there any options needed ? I tried different settings in putty, but I am not able to input any text, after I successfully breaked autoboot.

Thanks Jan

You need a good USB<->RS232 Adapter with 3.3V and need a few attempts to get in to uBoot CLI.

I had some trouble with a USB Hub.
The RS232 Adapter should be plugged into the backside of a PC or directly in your Notebook.

Hi,

I am already in the uBoot CLI, but I cannot input any kind of text in Putty.

I am using the red USB RS232 Adapter with 3,3V (the one, which work for other users), directly plugged into the notebook.
Are there any Putty options, which I need to set ?

No (115200,8N1)

Only use pin 2,3,4 (TX,GND,RX, may be switch TX/RX).
