eMMC connection problem [Answered]

[pomgrapes]

i have this emmc that i want to recover data from its a sph d710 phone the problem with the phone was emmc the blue light turns on so i removed the emmc from 2 phones that i have i used the pinout which i have and it keeps saying the same thing ERROR[001]: Can not connect. No target device present. for both i connect a different emmc but from a different phone but the same pinouts it connects normally what can be the problem here team please help me here is the picture of the emmc

Hello.

Most likely, You have soldered some wires incorrectly or there present some shorts between contacts on eMMC. Please check soldering and try to connect again.

Here are a few main possible reasons why the device doesn't connect:

1. You have connected battery or USB cable. Before connecting the device You must disconnect the battery and the USB cable, and then connect the device without power, this is important!
2. Some wires are soldered incorrectly. Carefully check soldering of all wires.
3. In the process of soldering, the resistors were burned (damaged) by using soldering iron or the pin pads on the board to which wires were soldered were damaged. Need replace damaged resistors and restore the pin pads on the board.
4. The ends of wires that were soldered, had not been cleared. Wire, that comes complete with Medusa Pro Box, is covered with an insulator, so before soldering need to clean the ends of each wire.
5. Soldered wires are too long. Make each wire as short as possible (3-5 CM length).
6. For GND connection use more thicker wire.

Also try to connect the device with higher Voltage level (try to set 2.0V, 2.2V) and with different Bus speed values.

already tried everything in your post the same wires i use them to connect diffrent emmc from a diffrent board works normally same length which is 3 cm long only the emmc is clean no shorts at all
