Can't flash or factory reset

I tried installing OpenWRT and seemed to have messed something up.

@anon50890781

it does change the boot (env) variables as per OpenWrt specifications and which are different from TOS.

I know that my best bet is to get a serial cable and debug it from there. The issue is, I ordered one, but considering the current situation, I don’t know if and when it will arrive. In addition, my old ISP is about to turn off my connection. So I’m looking for potential alternative ways to fix this.

Unless the device is an Omnia 2019 | 2020 model (CZ11NIC23) that shipped from factory with a u-boot version supporting ^[1]

5 LEDs: Unsecure SSH on 192.168.1.1 (Omnia 2019 and newer)

you would need to wait for the serial cable to arrive since that particular u-boot version has not been made available for other TO hardware revisions (CZ11NIC13 | CZ11NIC20) than the aforementioned.

In either case, if you want to re-install TOS (4-LED medkit via USB) instead of OpenWrt, you would need to

First reset uBoot (removing the OpenWRT customizations) with:
env default -a
saveenv
