I'm glad you're caught up. Can you do i tests I've requested?

Yeah I'll get to doing them soon.

Hi,

I have modded my demo-vita-3g-turned-retail. So basically, you need to have atleast 4gb memory card (smallest for the vita) to install molecularshell and vitashell then mount the usb drive?

I hope someone can automate the process of mounting the usb drive. And also, it would be nice to make henkaku unlock the internal memory for the phat and install molecularshell/vitashell in there so you wouldn't need a vita memory card.

I think all this has been done with the last update of Henkaku.

I thought molecularshell cannot run from ur0.

Well it's exactly as the titles says although here's the story behind this.
After I saw Yifan lu's amazing work on the MPCI-E SD adapter , I downloaded the eagle files and got the pin out for the PS Vita MPCI-E slot , from there I looked at the PS Vita GSM modem and realized the USB pins was all cut off from the PCB with two solder points , after this I did some work and added a USB port using some pins because I couldn't find a actual USB female xD

USB Connected(read notes)

UPDATE(MUST READ!!)
So after I yifan lu made me realise the most basic thing I missed (don't solder to the modem solder directly to mb) I fixed my error here are the pictures of the fix and the results.

Results that my PS Vita told me using Yifan lu's USB_detect/probe program:

Yeah I like spoilers UPDATE 2:

So I decided to add a proper USB port because pins aren't very practical :/, let the pictures explain the process.


The guts of it:

I had to get rid of a part of the PS Vita circuitry:

All wired up:

Note: Until a driver/plugin that supports this USB connection and mounting is created this is useless.

I also noticed that the PS Vita at some point (very early in me doing this) reacted to the USB and displayed a message "This device is not supported"(probably cause I didn't bother formatting to exFAT at that point)

I upload my work hours earlier on twitter: https://twitter.com/ZexceilXario

Your dream came true. See https://gbatemp.net/threads/yifan-lu-releases-usbmc-auto-mounts-usb-for-vita-tv.479205/#post-7480332

Not only can you mount it manually like yifan lu pointed out. But now this script can do it automatically for you.
