Hi i'm new on this forum but i repair phones since 4 years...
so if You have a problem with 6310 if i was You, i try this trick:

take a multimeter set in to meansure a PN (diode)
and + connect to gnd phone (anything metal)
and a - connector connect to all contacts on pcb (keyboard contacts)

multimeter should show You a value between 300 - 700 if doesn't ther is a trouble.

rehot Z300 (danger! it's near MAD)
if ok then ok...
if not
take off Z300 clear pcb and check connections to keyboard
if it's ok then rehot z300
if still nothing - change Z300
if still nothing i think it's a MAD or connections between Z300 and MAD

hi ,
