Experts/Team members, if there is a way to discover test point (if no information for the device is found on the Internet), kindly tutor us. Your knowledge is highly appreciated. I don't want to kill another device. Also this will help others not to kill a device by wrong short-circuit. |
Here is small guide for eMMC CMD LINE!
Every one of Embedded Multimedia Card eMMC use CMD line.
CMD: This signal is a bidirectional command channel used for card initialization and transfer of commands.
In that line you have to find 10K resistor which you must connect to GND
or short it during, or before contact USB to PC.
In most of cases Qualcomm platform will be recognized via your PC like DLOAD MODE 9008 QCOMM PORT instead bootloader/fastboot charged in eMMC memory.
That resistor in most cases you can find near to eMMC chip or Qcomm CPU
In other side CMD resistor is charged with 1.8v VDD
