R1 stopped charging

I believe some of you may have experienced this.

Not long ago, I plugged my R1 as per usual and it started recharging. Then the camera went into a loop of turning on / off like it usually does at startup but never stopped.

Since then, the R1 stopped charging.

I used different cables, charger, plugs, etc. No change at all.

So at this stage my R1 is not charging anymore and remains off.

Please assist / help.

Thank you
