Hardware Attempted USB-C mod wont charge

[ISAKING]

I got a Vita 2000 that I installed a USB-C board to. There are no shorts, there are two 5.1k resistors on the board but it just doesnt charge. Nothing literally nothing happens when I plug it in. It gets 5.3V on the board so idk what is wrong with it? I should also mention that I accidentally snapped off the side piece, it shouldnt matter tho right bcs thats only ground or?

Do you have any pictures?

Do you have any pictures?

Im sorry for very late reply.
I did try to reconnect the micro USB port and it too doesnt work anymore.
I did snap off a piece as u can see when I removed the micro USB port. My soldering is not the greatest either however its good enough for it to work so why doesnt it anymore?

First of, that soldering dont look too good. You should practice more on some junk pcb's and use more flux and heat.
Are you sure the is no short on the motherboard? You should always use the multimeter to check all connection before connecting power.
That missing part is most likely just ground. But if you have used enough force to break the pcb than you might have destroyed something else.

Sorry to say but this looks like a brick.

There are no shorts ive checked many many times.
The system works its just the charging that doesnt work.

The red wire is vvc I suppose? Is that a fuse right where its connected? With the number 36 on it?
When applying voltage how far does the power "travel"?

Edit: probably a resistor. I would check that and the capasitator next to it

These are the readings I was able to get.
The components above there all have 3.92V or 2.6V
Those 2 on the left I cant get a reading from so im going to assume they are whats broken.

 

[duffman2k]

Those that you maked as zero is data if I'm not mistaken. I can also se that a some of the copper layer is broken.
I would once again recommend more practice on some junk pcb's this soldering does not look to fresh, the data points is definitely shorted
No offence but I think you might have swallowed more then you can chew, I think your best shot for fixing this is giving it to a professional

Your soldered wires have too much metal exposed they might had been shorted when reassembled the Vita.

Try redoing the soldering with shorter metal exposed and apply enough flux as it will allow you to solder easier and faster, don't apply too much heat or you will ruin the pads. Use the smallest tip you've got available for your soldering iron, enough to heat the point but not too big to burn around other components.

Before doing that, and as already has been asked, check how "far" does the voltage reaches on the board and let us know.

I mean ive told u all there is to know, the voltage is right there in the picture its in every component related to the charging but somehow it doesnt end up in the battery

No offense but all u are doing is complaining about my soldering when thats not even the issue ?XD
its perfectly fine with no shorts there is something else going on

Your soldering is very likely the issue. If you look at your data points they are shorted, and also a connection is ripped from the pcb.
Keep curious and don't give up on modding hardware, but please for your own good practice before you start on relative experience hardware.
I would follow the trace for the vvc and see if any of resistors or capasitators are broken.

[...] but somehow it doesnt end up in the battery [...]

And that's precisely what you need to research.

You need to follow the traces with a multimeter up to the component that doesn't allow the voltage to continue its way to the battery.

Some time ago I found a page that shared all the layers of a PS Vita PCB board so you could follow the traces visually, if you can find it, it will prove very useful in this situation.

I've found it on Wololo, or search Google for "ps vita pcb view", its the first coincidence. I advise you the 7Zip file is huge.

Thats for a PS Vita 1000, I have a 2000.
Not sure how I am supposed to follow the traces when they are in another layer of the PCB.

Here is someone with a similar problem

Yeah I have seen that thread I guess I order those parts and replace them and see if it works

Let us know if you get it fixed! We're rootin' for ya!
