Hello.

If other chips are connecting without the problem, probably these eMMC has an issue(s). Try again to check soldering of each wire, check, whether there is no shorts between eMMC contacts, try to connect with different Voltage levels (try 2.0V-2.4V), try to set different Bus speed values. Also post here full Software log with the connecting operation.

some friend was telling that in the sph d710 model that the data is stored in the qualcomm chip do you think that is true or is it impossible also there is another Toshiba chip that is on the opposite side if the emmc what is that for?
