Archer C7 v2 rebooting every 12 seconds

I tried to update from 1.10 to 1.12 with gargoyle_1.12.0-ar71xx-generic-archer-c7-v2-squashfs-sysupgrade.bin under "update firmware" admin panel.

When i clicked 'upgrade now' i received a blank javascript alert, i think i clicked yes. I don't remember have seen any special lights activity, but at some I disconnected the psu by mistake.

Now that i turn it on, its rebooting a a predictable ~12 seconds. Is there anything to do?

serial cable

You can then see what's going on.

or a new router for you.

As in https://www.aliexpress.com/wholesale?ca ... rial+Cable ?

Following a guide like https://openwrt.org/toh/tp-link/tl-wr10 ... al_console ?

How am i going to manage the rebooting aspect?

Does it also reboot when not connected to the WAN?

If not, this might explain what's going on.

It just reboots about 12 seconds in. Connected only to the PSU.

Yes, only a serial cable will help here.

Ok, I'll get one, it'll take a couple of weeks to arrive. But then, what will i do with it? Flashing / Recovery using the serial console?
How i am going to work my way out if its rebooting every 12 seconds.

The usb-ttl just arrived, oddly enough, i recovered it through TFTP using this guide.

Now that i think, i never got to use the native firmware. Probably will continue with gargoyle due to familiarity
