4 flashing red lights and can’t charge or pair

[boris2]

My 1st gen square reader is only flashing 4 red light every once in a while, as I’m trying to re-pair the reader to my device. It will not flash orange. Before I disconnected the reader, the reader was not charging and stuck at 0%.

@boris2 ;

Charge your reader for a few hours 1 or 2, the longer the better.  Leave it Plugged in and charging, and try to Pair it to your Device.  Make sure your reader is only paired to ONE device, as these readers can only be paired to one device at a time.  So if its Paired to your phone and now you need it paired to a Tablet, it needs to be unpaired from your phone.  

I am not sure why your reader was not charging unless the charging port became damaged over time, or the actual charger was not plogged in and you thought it was charging.  My wife like to turn off Power strips which my items are plugged into to charge and then they don't thanks to the power strip getting turned off.
