Hello, world!
You see, a lot of times the Phone has no menu after installing MicroPython. Lucky for me, i know how to fix it.
Simple: Reset firmware.
anyways. bye.

Hey @Aswd,
thank you for reaching out. You can’t have Micropython and stock firmware installed onto your device at the same time. For this reason, you need to restore the firmware in order to get the stock firmware back onto your device when you are done with coding. However, you can still save all your sketches inside CircuitBlocks if you wish to access them again in the future 
Best,
Sandi
