so, anyone taken apart an MHL adapter yet?
i have a sneaking suspicion, that the move to an 11 pin is what will allow BOTH OTG, and MHL at the same time, but i could be wrong.
look inside your USB port on the bottom of the S3...
whatya see?
the normal 5 pins on the USB part.. but what is that in back wall? THE OTHER 6 PINS!
yep, that is why you cannot plug the MHL adapter into a hub or anything.. there is 6 pins are missing.
Now, i am wondering:
has anyone taken it apart to see if the 6 pins are used alone, or if it uses the the USB also?
if it uses only the 6 pins for MHL-ness, then it should more than possible to make an OTG/MHL adapter/dock.
more thought says, if my theory is right, an 11 pin to 5 pin conveter may be the key.. and an otg can be spliced in to give 2 outputs: MHL in one (using an s2 MHL adapter) and OTG in the other.....
anyone wanna tear their adapter up? or are you guys gonna make me spend some money?
I ran across this post looking to see if anyone has done this yet. I am going to try to grab the 5 to 11 tomorrow and tear it apart (since it's the cheaper adapter). My plan was to rip it apart and if the original 5 pins are available, splice just as you mentioned.
I can't find a decent picture of the microUSB plug to see if all pins are there.
Also I found this:
http://homixtech.en.alibaba.com/pro...Galaxy_S3_11pin_To_Micro_USB_5pin_Gender.html
Which makes me think 11 pin microUSB plugs that work are available out there somewhere.

So, did you do this experiment? Has anybody found a way to get access to all of the pins and make OTG work with MHL?
I've been waiting for two months for an answer about this. I'm glad someone started a thread. I kind of have this hesitation to start new threads.
I would love it if this could be integrated with the seidio active dock.

meh, I think that is wrong. many people have done exactly what it says you can do, and it doesn't work.
Makes me wonder if the boys at Samsung made a press mistake. If indeed you can't use both with the correct cable, then why make a port with 11 pins? Seems a waste of resources to me.

I have never seen anything from samsung saying that MHL and OTG was possible.. just speculation in websites.
It better be possible because if not all Samsung's managed to do is make us buy hugely overpriced new MHL cables when they could have kept the old type, but I guess Samsung's made some decent money giving people no option but to buy £30 MHL cables.
I hope Monoprice really is working on a cable. 35-40 USD is more than I want to pay, especially if I get a couple and/or an HDMI dock.

Someone needs to find the resistor values first so the phone can use both simultaneously if it's even possible that is.

It's not possible I think.
You can use an MHL enabled tv wich powers MHL, (so you don't need the adapter) but how do you want to split that?
You can split the cables from the samsung adapter, so you have the MHL ones(6) and the usb ones(5).
But what then?
You need to connect the MHL ones to an hdmi cable, and connect it with an MHL enabled tv. And the usb ones to an usb port for OTG.
But will that even work with this S3?, because it is designed to get power from your charger via the extra usb port on the adapter.
Maybe it only works with the adapter, and not even with an MHl enabled tv...
I think somebody needs to connect the S3 to an MHL enabled tv, if that works you can modify the adapter and use the usb as OTG.

I found (and shared) the MHL value, and we already know the OTG value.. but it only seems logical there is ANOTHER value to activate both at the same time. we are postulating, the the reasoning behind the 11 pin, is to allow both. If adding just an OTG cable turned on MHL too, it would cause issues without an MHL connection. and the same with MHL activating OTG, without an OTG device connected. like i said, this is postulation at the moment, but there SHOULD be a thrid value to enable both at the same time. that value would be used by a future peice of hardware that does a whole "PC MODE".
and if it does not exist, it CAN be done, we just need more "stuff" a way to enable a special switch if you will.
some people are saying you can connect straight to an MHL enabled TV, but that has not been done yet (and since there are no 11 pin MHL cables, that are not adapters, it seem unlikell that anyone will until said cable exists. the S3 cannot send MHL signal over the usb part, it has to be either the extra 6 pins, or with the 11 to 5 pin adapter.)
essentially, the pins are there, and with some special software, or a hidden resistor value as to yet, unfound, and some custom hardware (as of now NOTHING 11 pin, has 11 pins in it) it SHOULD be possible.
but there is nothing that has been found (hardware wise) that is even modifyable to work.... yet.
What I don't understand, why does MHL only work with the power connected?
They could easily make an MHL cable with the 11 pin, and hdmi. That should work for only MHL.
Only no go I can think is that MHL drains your battery because of always having your screen on, and the MHL output.
So they decided to use the adapter with power, otherwise you can't use MHL feature very long before your battery is empty
I think inside the adapter they only use the pins for giving power, and not the full 5 pin support for OTG, and therefore OTG doesn't work when you want to connect something.
Inside the ROM they have maybe build in something that MHL will only work when power is connected.
Maybe the solution is very simple,modify the adapter so full 5 pins are connected.

I doubt that'll work as it's not an MHL connector, which I understand is HDMI and USB combined, but if it somehow does... bargain!
Lol now i look properly its not going to work at all
imo very stupid not to use standard HDMI mini port... now we have to buy adapters and ****.. and the phone won't charge if you don't have special adapter.. epic fail imo.. anyway they should include adapters with the phone.
I agree, they should include the required cables and adapters in the box, other manufacturers like Nokia do with their flagship handsets.
I think MHL will ultimately be better than mini HDMI port though, since its looking very likely to become the next standard connection.
I'm hoping to get one of the MHL cable/adapters from the MHL consortium for my Clove Blog review, if I do then I will post up a youTube video for everyone. At the present time the consortium PR person is trying to procure one for me, but it seems likely its inordinately difficult, so remains to be seen whether I will have it in time for the review.
In the very least, you'd expect them to have manufactured and released the accessories by the time the actual phone is released.

First stock due mid-June just saying.
Can someone confirm for me that this is the same cable. They call it an Ethernet Micro-HDMI (Type D).
Edit: Monoprice[)0Tcom has them for like 5 bucks. I can give the link so you can see the cable once I get some more posts in here.
I'm not worried about the Ethernet part, it should not get in the way because the extra connections for it are female.
Also, there is a lot of great info on these forums. Look forward to sticking around and modding some phones in the future.
Edit 2: So when searching for the Samsung cable by Goog'ling the phone, they call it either "microUSB" or "HML port"
That site has two different types that they call: Mini-HDMI (Type C) and Micro-HDMI (Type D) the type C looks like the usual Samsung cable connection, I was just wondering if there is some different way they wired the Samsung cables so that we had to use those ones. I cannot see them doing that though since there are many devices switching to the same cable as well.
The trick is that standard HDMI so far does not include a link for power. The Samsung MHL adapter has a microUSB plug that connects into the phone and a microUSB jack to connect your charger, and the mini-HDMI jack to hook up to the TV so the device gets charged while playing back. In a future specification update, HDMI will probably be amended to include a power link.
Some info here: http://www.youtube.com/watch?v=ZtwTcnR0hqA
Clove told me that the MHL cables from different manufacturers will be compatible which is useful to know. I guess they all conform to the standard

the only reason that is my suspicion is because there are many "charging" products out there that don't really need data. Why there would be a need for such a small charging extension cable is beyond me, but it's the only solution I can think of, but I have no way of confirming or denying it either. The ebay descriptions seem to imply that the data wires are there, but we all know how reliable ebay can be...
Another idea I had was that it might be sensing the resistance in the cable, since, if I remember correctly, that was how some think/though the car dock puts the atrix into car mode without a magnet as is/was commonly used. Again these are just ideas.
Or the cable is just so poorly made that it's defective...I honestly have no clue
Has anyone got full lapdock capabilities using extension cables? I can only get the screen working and not the mouse and keyboard.
The HDMI extender was the hard one to find. There are other micro USB extenders out there, theoretically with all wires connected....

The HDMI cable seems to work. On the lapdock, with just the HDMI cable hooked up, it functions like it was it's an entertainment center.
The USB cord will need to be modified a little bit. I can't get it to seat right on the USB jack of the dock. I'll need to shave it down a bit as it doesn't sit down snugly.

I ordered the USB cable and experience this same problem, though I am waiting for my hdmi parts to come in (by April 6th I should have all my parts...). The cable itself works flawlessly as a micro usb extension cable when connecting it to the computer.
again as mentioned in the other thread, you want to be careful with the 5v coming out that micro hdmi port. for connecting back to your phone would be no issue, as the phone charges using this voltage, but hooking the lapdocks micro usb up to a host device probably wont appreciate the 5v coming back up the cable, where normally the usb device would be pulling power from said host, not providing it.
one suggestion is to just clip the red wire inside your micro usb cable/adapter.
btw the adapters i use do fit snugly side by side, without modification.
I've been following this thread for a little while now, and I wanted to share something I found.
I was looking at the Motorola Travel Webtop adapter. And I was curious to see whether it could be tweaked to suite our needs. I naively thought/hoped that I could flip the connectors in the device to make a small adapter to connect the Atrix to newer Lapdocks. Unfortunately as you can see in the pictures below (sorry not enough posts to link to the pictures) the two connectors are connected via a PCB not wires or a ribbon cable. Although I still have high hopes that I can de-solder the HDMI and USB connectors, and use a small length of flat ribbon cable to connect them and then re-positions the connectors in the case, to build a micro adapter to use the Atrix on the newer Lapdocks. Should this fail this will at least prevent others from making the same mistake, and solve the mystery of what's really inside the Webtop Travel adapter.
Do any one know if this Micro HDMI Cable would work for Lapdock.

http://www.gottabemobile.com/2012/06/29/galaxy-s-iii-new-mhl-connector-also-enables-usb-on-go/
Short: Samsung have changed to an 11 Pin-out to enable USB OTG and MHL Hdmi out at the same time. I purchased an original HDTV Adapter (EPL-3FHUBEGSTD) which as far as i can reliably count indeed has about 11 connectors inside the USB connector that goes into the phone.
Now, i can get HDMI out just fine, but ONLY when i also connect the MHL adapter to a power source (a PC USB Port will do fine), however i have also read, that the phone is able to power the MHL adapter itself but obviously would not be charged then (no surprises there). This does not work however.
Further, connecting a USB OTG cable to the micro usb port on the MHL adapter does nothing. No notification and no devices connecting. No power either, since the LED on my USB Hub does not light up as it should. Connecting any devices to the hub does nothing to change that situation. If i leave out the MHL adapter and connect the USB OTG cable directly to the phone, everything works perfectly. I have tried this with 2 different OTG cables so they are not the problem.
This is an original genuine HDTV Adapter for our phones, which according to that post should be working fine with USB OTG.
AFAIK, this topic --does-- come up more frequently now as i can find a few more discussions about it, albeit none really helpful:

That wiki entry is the most interesting link as it definitely states that using MHL and USB OTG simultaneously is possible and is also the reason why the 5 pin layout was changed to an 11 Pin layout.
Looking forward to reading your replies!

I don't see why you would feel the need to ridicule me for bringing up this thread. it's not wishful thinking, seeing as even the wikipedia entry on MHL clearly states it should be possible.

I don't really understand why people aren't looking into this more.
I'm not ridiculing you. I want the same thing. What I said was my legitimate wish list. I haven't bought the mhl adapter because I'm holding out for an all in one solution. I'm still waiting on Samsung to give us a product that does mhl and otg simultaneously.

I'm sorry, i must have gotten that wrong. I find it very confusing Samsung do no release enough information on this in order to make it work. Neither the phone documentation, nor the official 11-Pin HDTV Adapter manual mention this in any way.
I'm waiting also for a dock with MHL+USB OTG at the same time by Samsung, I dont understand why the official MHL adapter does not support this already but I've been searching and I have not found yet any example of both working together. It clearly seems that the MHL 11 pins cable we can buy right now does not support this since nobody has tested it succesfully but what I don't know is if that is related to Hardware or it also has something to do with software. I read a couple of weeks ago that Google was thinking about using the phone as a PC via docking, I think the idea comes from Motorola? So maybe the availability of both connections at the same time is also related with android, who knows, maybe in JB it will be possible...Has somebody tested MHL+USB OTG in JB with the official adapter?

As soon as i get home, i will try flashing this rom: http://forum.xda-developers.com/showthread.php?t=1695562
It comes with the latest stock kernel and appearently won't boot with anything else so Samsung must have made some changes to it. In a few hours time I'll be back with information on how that worked out.
I can confirm it NOT working on Jelly Bean. The MHL adapter does provide video HDMI output, but only as long as it is plugged into an external power source. When connecting an OTG usb cable, there is no reaction at all. There has to be some way of getting the phone to power the HDMI adapter. Do any of you folks have a good link to a kernel dev who can have a look into this? There has to be a MHL modul for the USB driver. Ghokanmoral probably has more insight into this...
Summary: USB OTG and MHL work fine separately, but not simultanously on JB using a standard genuine Samsung EPL-3FHUBEGSTD adaptor.

The final result of this is that USB OTG work with the Samsung dock, but not otherwise...and that is why they changed the pins to 11. For the dock to allow for OTG at the same time as HDMI out. Does everyone agree?

I don't really know how this is accomplished with the dock, but if it works with the dock, I have to think that the same technique could be used to make it work with other adapters, too. If it's a matter of putting a voltage or a resistance across two pins, that would not be a big deal to do.
It was figured out in the thread that this was split off of.
we already found the resistor value to do it, the wiring.. everything.
Anyone try...
Anyone try a usb Y cable which will inject power over a USB and still allow for a separate device to be attached? I would post a link but i'm noob here. You can find it as "UTStarcom USB Adapter Y Cable"
The HDMI part of the split HAS to be powered...but the USB OTG does not. So...if there was such thing as an 11 pin micro usb Y splitter, then the OTG side would work while the powered MHL adapter was on. Essentially this is what the dock does.
Is it possible to create an 11 pin Y splitter? Someone needs to get one of those docks and tear it apart to see how the leads are split...lol

http://forum.xda-developers.com/showthread.php?t=2142357
I've read through most of the postings about the GS3 and MHL/OTG going at the same time. I've been doing a lot of thinking and I'd like to know exactly what those MHL enable samsung TVs do to the HDMI standard that allow it to power the MHL adapter and phone. I've done a lot of power injection on ethernet and it doesn't scare me in the least...
what I'm getting at, I suppose, is that if the HDMI port is supplying the required juice, we can use the official GS3 MHL adapter for OTG and HDMI at the same time correct? if so, can we kludge an hdmi power injector right in front of the adapter, between the HDMI cable and the HDMI port on the MHL adapter? that $60 atrix dock is calling my name, but only if we can get it to work correctly.
I'm not having much luck finding out more about those mhl enabled TVs. Anyone happen to own one that has a multimeter?

as was figured out in another thread:
there multiple things making both not work at the same time:
1. as has been seen so far, none of the MHL adapters connect to the data pins on the usb of the phone (they do not have those 2 pins wired to anything, so no data can pass, they are all using the extra 6 pins for the MHL)
2. the 4th pin in the USB switches between different modes, it needs to be directly connected to ground for OTG, but it need a 1k resistor for MHL.. that means the phone will only switch one on, or the other.
3. the only possibility is: a fully rewired MHL adapter, with a custom resistor value wired in, and a special Kernel or ROM that would turn both on when it sees that special resistor.
we need hardware and software that do not exist for it work.

after searching a little bit about 11 pin port in galaxy s3 and take apart an 11pin to 5 pin adapter i am thinking about make DIY smart dock for galaxy s3
i ordered mhl adapter and waiting for it mean while i tried to connect usb otg and extra micro usb connector together so i can use otg and charge the phone at the same time. but the problem is when i short ground and seance pin for otg ; charging doesn't work.
so any suggestion about the project?
i attached a plan of my project here
edited:after failing my 1st attempt i succeeded to make it work on my 2nd try!
this time i opened a 11 pin to 5 pin adapter. it has a small resistor which is connected ground to sense pin for hdmi out put. i removed that resistor and i connected 5 extra wire in the adapter 1. vcc 2. data+ 3. data - 4. sense 5. ground ( i showed in picture) . then i connected sense and ground with a 40.2k resistor.
then the 4 wire, which i i connected in 11 to 5 pin adapter (vcc, data+,data-, and ground) , goes to a femele usb where you will connect usb devices or usb hub.
and thats it!! hope you can try it too. if if have any other question just ask me

AW: diy smardock for galaxy s3
You forgot the vcc at the otg side, but anyway it can't work.
While charging you send 5v through the micro usb to the phone.
But in otg mode the phone will send 5v to the usb connector to supply power for the connected device.
I think your only chance is to use the inductive connectors to charge your phone while in otg mode.

There seems no way like you want it. I told you the problem.
You have to use the Pins for the wireless charger (QI-charger) under the battery cover.

charging via the back pins while in OTG mode with throw a message popup that says over current protection and shuts down the S3
at least it does on mine.
I have the smart dock and after opening, it does contain quite a bit of electronics

I have a suspicion that the IC to the left of the Realtek one is the brains of the board. The RT chip does the hdmi out conversion and the other two longer IC's are usb host and usb audio. Can't make out the printed data on the unknown chip, but my best bet is if we can get a dump of whats on there then we might have a good chance of DIY hdmi/otg capabilities. i'm no expert by far, but just throwing ideas out there.

otg + charging success
hi guys! just want to give an update of my work.
i got otg and charging work together.
as in this post http://forum.xda-developers.com/showthread.php?t=1953061 i just connect ground and sense pin with a 40.2 k ohm resistor.
i ordered 40.2 k ohm resistor which i just got tonight. the hdmi adapter i have is a cheap and old one. its not mirroring the screen. i ordered a new Rocketfish MHL HDTV Adapter . hope that will work!! waiting for that to arrive!!!!
here i am giving 2 screen shot
mess lol
and here what i did so far....
i didnt connect micro usb female port for data sync because those i didnt get yet.
if anyone have any suggestion please tell me.
hoping to make it work.....

Great work, necomer. I've also been trying that for two months now, but haven't been able to make it work. I have the 40,2 KOhm resistor between sense and GND, and am able to launch smart dock mode on some ROMs I have tried. So, which ROM are you running? My only idea here is that maybe you having a US S3 is what does the difference (well, I'm assuming that, maybe you have an international one).
Thanks in advance, and once again, great work :good:

I'm pretty sure your buying the wrong MHL adapter. The Note II and the s3 have a different micro usb than any other phone and require the samsung
MHL adapter.
Not sure what you are trying to do?
Amazon sells a combo cable so you can use OTG and charge the device at the same time. I use it to connect a 1TB portable drive to my S3 and Tab 2 10.1.
I bought the official Samsung HDMI adapters for both devices. They are powered and stream over HDMI to my TV just fine. Works with just about everything I've tried although some services require some workarounds. Copy protection crap.
What you are trying to do sounds risky. You might fry the phone.
I apologize if I haven't grasped your intentions but I'm kind of slow.
Edit: I think I may get it now. Are you trying to power, feed external data through OTG and then stream out to an HDMI display?
Dumb question as I said I'm slow but, how about the official Samsung HDMI adapter and use the power in port with a powered OTG combo cable?

what i am trying to do is, use otg , charge the phone and use hdmi at the same time. i thought it would be easy bcz samsung made new 11 pin connector in Galaxy s3 . so apparently its supposed to work ,as they are not using same pin for transferring data. But i dont have any idea about internal proses. while charging and otg at the same time is possible, dont you think we can connect hdmi with it in any way?
well all this is just guessing from my little knowledge. i want some suggestion from those who worked on this and correct my mistakes

Maybe... it's a HDCP problem...
If your TV don't support HDCP function(or authentication failed), then MHL chipset will show a black screen
(HDCP : High-definition Digital Content Protection)
I was going to this topic, being all hopeful that I finally might get my S3 in OTG+Charge mode. And then it turned out it only worked on a phone still running 4.1.1. I have 4.1.2, and OTG+charge did work for me before, but it seems Samsung broke it in 4.1.2. It is probably the fault of the kernel that came with the XXELLC (a stock 4.1.2 ROM) update, but how to fix it is beyond me.
Are you serious! I won't update mine then. I need to use that together! !!
