i9300 emmc to sd


hi brothers,

my old phone was dead and i wanted to rescue the data from it .

i saw a dude on internet soldering the emmc to micro sd carder and dd the

whole emmc to an image file but i am wondering whether the BGA pins is

responsible for the sd card reader .

1 – CAT3
2 – CMD
3 – Vss1
4 – Vcc
5 – CLK
6 – Vss2
7 – DAT0
8 – DAT1
9 – DAT2

i just got 5 pins from the pic on internet ( Data0 , CLK , CMD , Vccq , vcc ) where is the remaining point i need to solder for the sd card reader?

Thanks deeply
