Hi,
I bought this router a while ago (2022) and attempted to flash it. I used the following:
openwrt-22.03-snapshot-r19228-0877953235-mediatek-mt7622-linksys_e8450-ubi-initramfs-recovery-installer.itb
openwrt-22.03-snapshot-r19228-0877953235-mediatek-mt7622-linksys_e8450-ubi-initramfs-recovery.itb
openwrt-22.03-snapshot-r19228-0877953235-mediatek-mt7622-linksys_e8450-ubi-squashfs-sysupgrade.itb
Something went wrong and I had given up.
I'm trying again. Turning it on, the power LED glows white and the internet LED glows amber. I connected my desktop eth1 to router ethernet LAN port 1. Ran dhclient on my desktop and got an IP address for eth1, 192.168.1.187. The router responds to ping. Browsing this address brings up the nginx startup page. ssh root@192.168.1.187 brings up a password prompt. Empty password is incorrect, also obvious choices like 'root', 'toor', 'admin', etc.
I'd welcome any suggestions, or even an authoritative "call a priest". Thank you in advance.
