How do i reset a T5577 chip to "EM410x" the way its shipped from DT?

Hi there!

I recently configured the NeXT (125khz part) as a Kantech ioProx chip.
How do i reset it to it`s default state?

Please provide a writeup.
(I`m using the Proxmark3 RDV4.01 with the custom made DT-Coil)

Just look up EM410x cloning with a Proxmark. If you set it up, you should also know the passcode you put on it, which you’ll need to reconfigure it.

The instructions on the link didn’t work… @bepiswriter

Which step failed and in what way? Can you provide the output of the proxmark at that step? What’s the current output of lf search?
