My FP2 is also dead and getting deader by the minute.
I have been so happy with this phone and it’s worked pretty much perfectly from day one…
…and then yesterday it seemed to run out of battery really quickly, I put it on charge over night and in the morning it was on 4% battery (presumably hadn’t charged) and then died.
I got it started, by removing the battery, SD card and SIM then plugging in the charger with the battery removed. The Fairphone flash screen shows, then quickly put in the battery and it booted and started to charge (slowly). Up to 70% charge and working just fine by mid afternoon. Plugged it in to complete the charging when I got home and two hours later it was dead.
After the second death the fairphone flash screen came up when the charger was first plugged in (but the start with no battery trick no longer worked). But after several attempts, now NOTHING comes on except the red LED which flashes or shows steady red (and only that if I push the USB connector in really hard).
This could just be a USB socket fault (probably dry joints in the connector to PCB solder) or some other fault with the bottom (power input and microphone) module. However, it’s all very well having a phone with replaceable modules … but if you don’t know which module needs replacing and can’t get a spare … it’s hopeless. Battery dead? Charger socket failed? Who knows.
I’ve logged a support request but little hope of getting an answer any time soon (from what people here say) so, now I’m forced to go and buy a nasty UNfairPhone to keep my business running … which kind of spoils the point of the FairPhone … arghhh!!!
Anyway - marc, try the battery out, charger in, start, battery in … routine; it may work at least once for you - just to get the travel docs out.
