Backup / recover AR150 firmware

Routers
1

hi,
I need to recover / to backup custom FIRMWARE from AR150.
What option do I have ?

I do not have SHELL access to AR150.

I can boot to UBOOT web interface, but see no option to backup firmware, only firmware update.

Thank you for your support.

PS: I tried this, but it does not work too (probably it is not enabled in uboot)

There is no way to backup firmware in UBOOT.
Can you access luci? Luci has an option to back up firmware
I don’t think it’s enough just to back up the firmware, it should back up the whole flash

Especially the ART partition… don’t’ want to lose that one

OpenWRT master has implemented partition backups once up and running
