How to reset Antminer to factory settings

How to reload with latest official firmware? If I buy old L3+ can I reload the latest firmware and how do I do that? Please make a video of that.

after doing that i cant get it it says wrong password

Hi and good day! We recently purchased a secondhand antminer L3+ and we are having problems with accessing the miner's user interface. The browser won't load the IP address of the miner given by our router and we have tried several steps like reset the miner. Can you help us.

the intro is as loud as the miners

I reset my l3 miner and the upgrade option is not there anymore and I don’t have as slot how can I change the firmware help :)

Lol you can tell they’re running a massive amount of API fetch, etc, with how much the screen recording shows the lag.

I mistakenly set my ip to static, now the miner isnt mining and I can't connect to it. Even the switch and router can't pick it up. Any ideas on how to reset my machine? None of this is working....
