- First, take your phone’s back cover off. Then, remove the battery, fingerprint reader, and camera from the motherboard.
- Unscrew the screws that hold the motherboard in place, carefully remove it, and put it in a safe place.
- Find the TxOp, TxOn, RxOp, and RxOn pins for the eMMC on the device. You might have to cut through the steel cover to get to them.
- Get the UFI box, then take the adapter out of it. The pins on the adapter should be the same as the ones listed in the last step.
- Between the base and the adapter, use jumpers to connect the four pins (TxOp, TxOn, RxOp, and RxOn). Leave the USB to power the VCC and VCCQ.
- Put the connector into the UFI box and connect the box to your computer.
- Connect the battery to the computer again. Then, connect the phone to your computer using the USB connection.
