Need specific technique and talent! And read manual that is found in sticky thread!! Where did you post screen short and logs within this period with more information about mobile condition and the process that you have followed? We are not Almighty to find the task that you are feeling inside your heart :P ............. . As you have told a serious lie  that you have tried many times but I did not see any screen shorts, logs etc except 2 total post you have been created with this id till March 10, 2016.BR Dipendra Pathak |

Member: 2172855 Status: Offline Thanks Meter: 0 | Hello mr. Dipendra Pathak, thanks for your answer. These are my first posts as you can see. Sorry if I didn t explain myself correctly on my last post. I am trying to read directly from the emmc chip because the phone (a galaxy s4 mini ) is severely physically damaged. The emmc model is a sandisk sdin7du2 8GB i have checked all voltages of gpg ft232 board and they are ok. Before reading I have removed all excess of tin and cleaned the chip pads very well with alcohol. The soft detect all connection in green so I guess that ic is correctly placed. This is the log generated by the gpgemmc when i try to read the emmc memory Connecting... SN:00000102289 Get License data... Verify Liecnse data... Version:V3.2 Device Ready...OK! ------------------------------------------------------ Reading... Pin Check up... >>Loose contact Is possible this is a problem of pullup, i need weld a resistor to do pullup? Is possible sometihng in the utility i dont setting? Thanks to answer i still trying to uploads the photos |

Well friend, seems you are using GPG EMMC version 1. if so, you need to use GPG EMMC Power Adapter for it that gives more power for Reading your Chip and this adapter is free of cost which you will get at the time of buying Box. OR, you forget to join external power supply for GPG Emmc. Am I right ? Well, Both EMMC Boxes are same but Version 1 box need to join EMMC adapter with it where as Version 2 has inbuilt so can do operation directly. BR Micro Mind | |
