LuCI Attended Sysupgrade support thread

tbrautaset · February 5, 2026, 11:03pm

I’ve tried sysupgrade, owut, and most recently using
Attended SysUpgrade, but I consistently receive the following error:

Server response: Unsupported profiles: asus_rt-ac3200 & asus_rt-ac5300.
The requested profile was either dropped or never existed.

I’ve also opened an issue for this:

target/bcm53xx bug Official Image SNAPSHOT

### Describe the bug ### Description On bcm53xx devices, specifically ASUS RT-…AC3200 and RT-AC5300, `sysupgrade` does not reliably preserve configuration across upgrades, even when invoked without `-n`. This has been observed multiple times during testing and does not appear to be related to insufficient overlay space or explicit configuration reset. --- ### Devices tested - ASUS RT-AC3200 - ASUS RT-AC5300 --- ### Observed behavior - `sysupgrade` completes successfully - `Overlay is present and writable after reboot; this does not appear to be a mount or storage space issue. - Parts or all of the configuration under `/etc/config` are missing - No explicit errors are reported during the upgrade process --- ### Expected behavior According to OpenWrt documentation, `sysupgrade` should preserve the existing configuration by default unless `-n` is specified. --- ### Reproduction steps 1. Flash OpenWrt on RT-AC3200 or RT-AC5300 2. Apply basic configuration changes (e.g. network, wireless, system) 3. Perform an upgrade using: ### OpenWrt version r32644-31cdd13d22 ### OpenWrt release SNAPSHOT ### OpenWrt target/subtarget bcm53xx/generic ### Device ASUS RT-AC3200 & ASUS RT-AC5300 ### Image kind Official downloaded image ### Steps to reproduce Perform an upgrade using: sysupgrade /tmp/openwrt-*.bin or LuCI → Backup / Flash Firmware or Attended SysUpgrade (ASU) ### Actual behaviour After sysupgrade completes and the system reboots, parts or all of the configuration under /etc/config are missing, despite overlay being mounted and no explicit configuration reset requested. ### Expected behaviour The existing configuration should be preserved across sysupgrade by default unless -n is specified. ### Additional info Observed only on SNAPSHOT builds so far. ### Diffconfig ```text ``` ### Terms - [x] I am reporting an issue for OpenWrt, not an unsupported fork.

Both devices are running correctly, but Attended SysUpgrade reports the
profiles as unsupported.

Could these profiles please be added ?
