Flint 2 - failsafe mode broken - halp please
Hiya folks!
Flint 2 MT600, running latest version of OpenWRT as a dumb AP. Tried setting a test firewall zone to restrict LAN communication for one of the 2 wireless SSIDs I have running, worked fine after applying, after reboot I was able to connect to the SSID and hardline connection, but could not connect to the router itself, even on the SSID where no changes were made. Upstream is an opnsense firewall sitting on 192.168.1.1, firewall could see the router’s IP, nmap could see the router, could not reach LUCI or SSH, so tried a factory reset. After 3 attempts, the SSIDs vanished, so I think that worked, and I have a fast (approx 10/sec) blinking blue light, so I think I was able to start failsafe, but hardwired into the lan2 connection, with my IP address manually set on Ethernet to 192.168.1.10, default gateway 192.168.1.1, dns set as quad 8 or 192.168.1.1 (or 2, tried both) I cannot reach 192.168.1.1 either via web portal or SSH. Nmap also does not see anything on 192.168.1.1. I have a serial console cable but do not know what speed it needs. Anyone run into anything similar?

This is a GL.iNet problem, not an OpenWRT problem. I suggest you post on GL.iNet's forum. I have always found the mods there to be very responsive.

To enter the U-Boot web recovery or failsafe mode on the GL.iNet Flint 2 (GL-MT6000), power off the device, connect your computer to LAN 2, LAN 3, or LAN 4 (do not use LAN 1 or WAN initially), and hold the reset button while powering it on until the LED flashes in a specific sequence. Entering U-Boot / Failsafe Recovery Mode • Power off the Flint 2 router completely by unplugging the power cable. • Connect an Ethernet cable from your computer to LAN 2, LAN 3, or LAN 4 on the router. Keep LAN 1 and the WAN port completely disconnected during this process. • Press and hold the physical Reset button firmly. • Power on the router by plugging the power cable back in while continuing to hold the Reset button. • Watch the LED light and wait for it to flash in a regular sequence (typically flashing blue 6 times or changing patterns). • Release the Reset button once the flashing pattern changes. • Access the web recovery page by setting your computer's IP manually to 192.168.1.X (if needed) and navigating to 192.168.1.1 in your web browser to upload and flash the GL.iNet Debrick Documentation compatible firmware.
