Linksys v1.1.01.272918 can't downgrade

[Hadyark]

I don't know why i can't downgrade to the [FW_E8450_1.0.01.101415_prod.img] (https://downloads.linksys.com/support/assets/firmware/FW_E8450_1.0.01.101415_prod.img) ? I'm currently in v1.1.01.272918

Do you have any ideas why ?

Strange, I always thought that signature checking is only active in version 1.0.02.*, but it looks like signature check is now enabled also in this firmware you got there already. If you just want to install OpenWrt, use the *_installer_signed.itb, it should work.

Thanks, it worked for me

Same here with firmware version 1.1.01 build 272918 Mar 29, 2022 (device bought in Japan). Using openwrt-22.03.3-mediatek-mt7622-linksys_e8450-ubi-initramfs-recovery-installer_signed.itb worked.
