Xioami AX3200 sysupgrade image check failed

Hello,
I manage a Xiaomi Router AX3200 router
This device is running OpenWRT 24.10.4 r28959-29397011cc

Link: [OpenWrt Wiki] Xiaomi AX3200 / Redmi AX6S

I would update the firmware to 24.10.5, to install the latest patch (this patch fix CVE-2025-14282).

I downloaded the firmware from this link https://downloads.openwrt.org/releases/24.10.5/targets/mediatek/mt7622/openwrt-24.10.5-mediatek-mt7622-xiaomi_redmi-router-ax6s-squashfs-sysupgrade.itb

I uploaded the firmware (Luci > System > Backup / Flash Firmware > Flash new firmware image), but the image check failed.

Moreover:

I runned "run hexdump /dev/mtd8 | head" -> output returns a value that starts with 0000000 0dd0 edfe

I runned "run fw_printenv | grep -e ^flag_try -e ^boot_fw" -> I applied the temporary fix "fw_setenv boot_fw1 'run boot_rd_img;bootm'"

Have you already faced the same issue?
I would avoid to brick the router :slight_smile:

Thank you!
