About 11 days ago I managed to successfully install openwrt on the specific router with the expoit.
Today I wanted to download the last snapshot to upgrade. The router unfortunately became bricked but fortunately thanks to this post https://www.arednmesh.org/content/how-unbrick-tp-link-node I managed to pass the original firmware in Chinese. Then I did the same procedure again, but while it shows that exploit is acceptable on the router, the router never starts. It stays stable with the orange light permanently on.
Any help is welcome
