@HUM ,
first messure 3.0v & 1.8v from two regulator N5250 & N5251 , messure 3.0v at R5276 & 1.8v at R5275 .
if found missing or abnormal replace it's corresponding components ( as in picture 1 & 2 )
if voltages are ok then replace micro sd level shifter ic (N5252) as shown on above picture. ( but I found in most cases problem is in regulator output voltage )
if still same problem mmc not detected then u need to reball or replace 8gb mmc ic D5250 . ( as in picture 3 )
