Hi,
I've replaced the screen of my OnePlus One and, when I connected the charger, it said that battery was to low to start up, everything fine so far. I left it charging for a while, but it remained at the 0%, so I guessed I had not connected the battery properly. I disassembled and assembled again the phone, but now it won't even show the charging progress. If I connect the charger (no matter if the battery is plugged in or not), it just vibrates once and does nothing else.
