What happened?

Hey there,

3 of my controllers can't update.

This is the info for one of them displayed in the settings:

Installed version: WLED 0.15.2 (2508020) "ESP02" (Processor: ESP8266)

How exactly did I manage to install an ESP02 version on an ESP8266?

The controllers are from China, I have no idea whats actually inside of them and opening them would mean quite a bunch of work.

I've tried ESP8266 images - "Not enough space" Same for ESP02 images.

It also shows Installed version: Unknown Release: Unknown in the update menu

I did try to compress the bin myself but then it didnt pass validation - As do the compressed images on github.

What exactly can I do here?
