[QUOTE=jointaccess;9366066]1, 9900 No power, No red light

until now no solution for this issuee,,,,but u can chek this VREG_MSM_C2 at C1233,,,this voltage use for VDD_C2 (main CPU suply) is short circuit? if yes,,,CPU damaged

2, 9900 goes off when network is activated, but when the wi-fi is activated it will not go off again but drains battery.

please remove R301,,,this part separate between VSYS and VSYS RF,,,so you can fix problem came from base band or RF section,
