HI
Just saw a video with very bad quality giving a temporary solution for the battery charging problem because of IC (QFE1101) inside the shield just on the up side of the battery connector failed.
So what you need to do is to add in the pads right after the battery connector on the left side, a diode with the cathode to the upper side and the anode to the lower pad and the phone will charge.

Please be carefull when the battery is very low, because the diode will be very hot because to much current is draining from it. Never let the battery go to a very low voltage so that will not happend.

Hope i help many ppl with this problem.
Regards!
