Removed all opkg packages. How to return?

Question

Network administration

Good afternoon!
I ask for help and advice.
Installed Openwrt firmware on tp-link wr741nd v4.20. Played with packages, clogged memory. I began to remove packages: opkg remove "package", but there were no such packages. And in the heat of the moment I did opkg remove *. And the router seems to be working now, but nothing can be done with it. Even reload!
How to competently act in this situation, so as not to finish off the device?
Thank you!

Answer 1

Do a reset. Everything should be fine after that. Well, or as an option yum install (the name of the package that was removed)
