[HELP] Anyone for PSP Go

Ensure a cable has ALL the pins in there by looking inside the connector.
Disassemble the cable head (there should be a seam on the side, use adequate force to break the plastic along the seam)
Expose the board. Use factory-soldered USB cables and trace patterns for guidance.
Odd numbered pins are on the top side and even numbered pins are on the bottom.

If your PSPgo's battery is fine - you don't have to wire pins 20 and 22.
But if it's not, make sure NOT TO USE YOUR TTL ADAPTER'S 5V LINE IF YOU PLAN TO SUPPLY POWER OVER THE CABLE! Adapter's power supply is not capable of powering your PSP alone and you need to wire something in parallel, such as a USB power cable.

Make sure to ground TOH0. Select 1.8 logic level on your adapter. Connect adapter GND to GND, adapter TX to PSP RX and vice versa.
If your adapter is incapable of 1.8V but you know its logic level, you can get away with using simple resistor dividers on TX and RX lanes.
I think you may be able to join them into one-wire bus (aka K-line) with a 1n4148 diode like in PSP-3000 jig assembly to get away with just one voltage divider

buy one from Peter Lustig

The same you tell me in the past, if have money to buy it, I wouldn't ask here, and this guy promised a tutorial how to make the cable, something that didn't happen. Anyone else don't know how make this cable with another parts combined ?

We all bought 1.8V TTL adapters. Also, you need to disassemble the cable and change pins inside their connector. It isn't very simple procedure.

Understand, for that i say if anyone try it with other, can't get 1.8V TTL unfortunately (and in case I found 1.8V TTL we need a tutorial how to make it and no one has made) , in this photo i see the head of the cable is untouched and the other side has been cut to connect to TTL

The cable head is modified as I wrote before. I think work in progress photos was posted somewhere in Twitter.

I don't have twitter. Yeah before 5 months, but now the cable head from the side of psp look untouched or it's so well made it doesn't look like it's been modified
and in case I found 1.8V TTL we need a tutorial how to make it and no one has made, for the pins you said
New

Old

Did you check the Wiki for pinout?

Yeah, i read it, but not fully understand it, i'm not expert like you, if have a tutorial, instructions for how disassemble the cable and change pins inside their connector in psp cable, maybe i can make it, if get a 1.8V TTL like FT232RL, unfortunately for now can't get it is not anavable in my country and the only parts i have now is the above i write in first

Thanks you for this. This is a tutorial
(And sorry ask much but because i don't have vision from my one eye is difficult to focus in small details and this take me some time, but i try my best)

Yeah battery is fine
unfortunately still don't have the FT232RL need it for this and can't get it for now, i have USB to Serial Module - CP2102, DC-DC Step-Down 1.8-12V 2A - MP2315, 4-channel I2C-safe Bi-directional Logic Level Converter - BSS138 and resist and diode and the non original psp cable

My cable
As i see have all same color but mine have blue not green (maybe is dark green)
And the white is the D- and Dark green D+

If only I had pictures like the ones I uploaded, let me see exactly where it's soldering
