Attention! This way is not safe for working pcb.

For pinout find need:

1. Need Multimeter.
2. Need PCB with emmc.
3. Sodering stationg.

Now steps.:
1. Here pcb. for example we take GT-I9500 board.

2. Multimeter.


3. Here pcb with removed EMMC.

4. Here pcb with market pins. Check position point before start job.

5. Here default pinout of BGA169 emmc with position point and pinout.

6. Now using tester need test where go pins.

LETS GO. Now you can connect to emmc.
Check this FAQ - How connect EMMC DIRECT!!!!

I am trying to read the eMMC chip on a LG MS770 phone that is in working order. The eMMC chip is a Toshiba THGBM4GGD2HBAIC 4GB chip. I traced back Vcc, Clk, Cmd, VccQ, and D0. However when I attempt to read the eMMC chip I get the following error:

EasyJtag Suite ver.: started.
Operating system ver.: Windows 7 (build 7601, Service Pack 1), 64-bit edition.
Successefuly connected to box on COM39
Box S/N: 16XXXX, ,FW Ver.: 01.47

I have rechecked my connections and reconfirmed my connection points on my test phone. See attached image for solder connections.

Any suggestions?

Mr. Blang,
Feel free to add this pinout image to the Easy-JTAG LG MS-770 support files. Using the attached eMMC pinout, I was able to dump the Toshiba memory chip. I have included the log from Easy-JTAG to confirm the connection:

I think the main problem is to find out the datasheet of the used eMMC in a particular mobile. Is there anywhere an eMMC datasheet of eMMC chips where i can see which eMMC pin is
VCC,VCCQ,D0,CLK ... .?
