First, turn your meowbit off, then hold the menu button and turn it back on. This will put your meowbit into DFU mode. Then, get the CONFIG.BIN file and run this command sudo dfu-util -a 0 -s 0x08000000 -D CONFIG.BIN (or similar for windows). And there you go. The original bootloader is back!

Wowwwwwwwww!!!
Do you have the command for windows? I have
a raspberry pi 3a+ and do not want to run it with 512MB of ram.
Iām currently in China and it is really fun 
(High speed rail!! Max speed 380km/h but normally 240km/h)
Iām returning home in the 28th of January and I will try it first thing when I arrive.
Thanks @Renderthegreat !!!
Download from here, then run the same command but remove sudo and add .exe after dfu-util. You can get the CONFIG.BIN from wget us.renderlabs.cloud/static/meowbit/CONFIG.BIN -o CONFIG.BIN

Also this says that the meowbit is
in the list of supported devices as the meowbit is a STM32F4 device.

Also when I did that I heard that familiar sound of usb devices plugging in and this appearing in device manager

Also because dfu-util was almost impossible ! just downloaded stm32cube programmer and apparently you had to hold down the menu button for it to connect but for the second time I didnāt need to.

How to fix meowbit with DFU-Util
How to use DFU-Util.docx
do this work on normal makecode arcade
I donāt know what is a āmakecode arcadeā but if you have the CONFIG.BIN file and you know how to put it in DFU mode, it should work
why would you touch that?
i can read json files like a book but am still scared to touch a locked pxt.json
nvm im just panicking
Bro, wth. This is a firmware bricker. It peels off the warranty off your meow bit. Donāt flash it. And if you want to, make a backup of your firmware via STM32 Cube Programmer.
thank you very much!
Success, V1.6
@AqeeAqee I want to mess around with the UI of this a little. Iāve already forked the repo and Iām just wondering if this is safe. Thanks so much!
@AqeeAqee i have no idea if you are still active at all, but i could really use some pointers in making my own Meowbit custom firmware. Please help me if you have the time.
