Are these PS3 error codes?

Here is the list of PS3 error codes and none of these are listed ;

8071053D - Hard boot the PS3, turn off the PS3 to stand-by, flip off the back switch and completely remove the power cord. Shut off your modem/router, for approx. 5 minutes, then turn the modem back up first and let it sync. Then turn the router back on (if you're using one) and let it sync. Reconnect your power cable and flip the back switch up again. Then make a new network connection

(This is a hard reboot of your PS3 which may be worth a try!)

Perhaps the error codes have different identification codes in France.

Bonne chance!

If you can stream media from the pogoplug to a NAS (Network Attached Storage) and PC (Windows OS, MAC OS or Linux) then I think the problem is with PS3.

Try rebooting the PS3 as suggested in my last post then check that you have setup to this method;
