I had a working setup with RePhone + SIM + battery and was able to make HTTP calls etc.
All of a sudden, I have the following problem:
A few seconds after RePhone is powered on, it just switches off. The duration is too short for me to plug-in the USB cable to see any logs.
If I remove the SIM, it works perfectly fine (as in, it stays on, I can flash new application etc.)
The battery is at 4.1V. Nothing else has changed from when it was working.
Any idea what could be wrong?
