MHL Pinout/Splice up HDMI and Micro-b cable? - Android Q&A, Help & Troubleshooting

Is it possible? I just got an AppRadio2 and would like to install it this weekend. I don't have an MHL cable right now, and don't want to wait for Amazon shipping. Is it possible to cut up an HDMI cable (I've got a dead one lying around) and a micro-b cable and solder them together?

Bump, no one knows?

cannot splice HDMI & Micro-USB together
my apologies to mods if i dug up an old thread
to the OP..
NO you cannot just simply splice them together, there is a special chip that interprets the MHL signal from the phone,
into the proper HDMI signal to output to your HDMI source..
this example of a SIMG MHL Adapter that i am incorporating into a NFC smart dock for my Xperia Z Shows the MANY components involved..
see below IMG file
as you can see by the external ports... on the top side is the internal micro usb charging and power supply, left side is the micro usb input from the phone itself, right side is the HDMI output, bottom side is the IR receiver
and in the middle, the lil black chip is the SIMG MHL decoder microchip

Mod for TV out?

I know that SG2 is only supposed to do TV-out via samsungs proprietary cable and that TV out via headset output is not enabled. Is there a mod to enable it? I´ve tried the same nokia cable that used to work on GS1 and I could only get sound.
I just got an official samsung one from Ebay for $15 and it works perfectly. Sometimes it pays not to be cheap
Nah you can only use TV out through the micro USB port. I bought a generic adapter off eBay. AFAIK it is not possible through the headphone jack and no hack will make it work.

where is the setting for tv out?
how to connect to tv?
I´ve found a lot of regular USB to RCA cables on ebay, but I didn´t find any MICRO USB to RCA.
The GS2 has MICRO USB port, right? Or is it Mini?

ASUS Extension Kit - USB-adapter
My question was whether I can connect an external HDD without this adapter, but using female to female usb adapter or usb to mini usb.
they don't sell this adapter in my country yet (they started selling the prime about a month ago) and I wanna know if I can manage to connect it without this adapter.
Your cable proposal should work - the only thing is to try and keep the cable as short as possible. I think the USB spec. says something like the minimum transmission speed must be met with a 5m cable

Where can I buy one of these?

Does anyone know where I can buy one of these? It's a Motorola car dock cable. It allows a single connection to the phone on one end with a USB (for power) as well as an AUX input on the other. I can't seem to find just the cable. I don't want to have to purchase the entire dock!

The cable itself won't work with charging. I get my gf the Droid 3 and got the car dock for free and that's the cable it comes with. found out that without the dock itself the cable is pretty much useless. It won't really charge anything and aux won't work either. Tried it on my Rezound while driving her car and also with her phone too

Question about original Samsung micro USB cable

I have misplaced my original micro USB cable and charger.
I just ordered and received what I think/hope is an authentic Samsung cable and charger. I have plenty of aftermarket cables but I wanted to get the real thing to increase the odds that CASUAL/No You Verizon will work when I try it.
The items look/feel real. However, on the end of the cable that has the micro USB connector that plugs into the phone, there is no pin in position #4.
(refer to this diagram for pin positions: kineteka.com/Media/Default/Page/micro-usb-b.jpg)
Can someone verify if their original cable has a pin in position #4?
I understand that pin #4 isn't actually needed for charging/syncing, but this will help me determine if what I got is actually a genuine Samsung cable.
Thanks!
There is no position 4 pin on mine.

Thanks so much for responding AND for posting a pic!
That looks exactly like mine. I think I got the real thing.
Thanks again!
