all thanks goes to:https://www.instructables.com/id/Make-a-USB-OTG-hos...
for this intructable.
Step 1: Usb Cable
i used a usb cable i had that was shorting and not a new one for this instructable.
electrical shrink tube
if u have a female to female adapter all u have to do is make the usb cable shorter an not change the end.
first i cut off the male end of the usb to the length i needed then connect the wires using the link / instructions in my intro.
i then plugged it into a samsung s3 an the phone recognized it as a mass storage device which means all wires was soldered to their correct terminals.
Step 2: Securing the Wires
once all wires were soldered correctly i then used hot glue to insulate the wires from shorting on each other then used electrical shrink tubing to further insulate and make the cable look appealing.
Step 3: Finish Product
the female to female adapter and a flash drive were all put together then connected to the phone.
the phone recognises and can open and transfer files using the OTG cable made from a old usb cable.
