Running SGH-I927RUXKJ5_STOCK_ROOTED. Phone reboots when plugging in a Micro USB to HDMI MHL Adapter. Upon reboot phone operates normally but no display on the external monitor. Anybody have MHL adapter working on Captivate Glide? Thanks for any help.
I ordered mine on ebay.
Phone doesn't reboot when connecting MHL cable.
But no video output to HDMI ...
I'm running Rogers ROM + Cranium kernel.
Edit :
it works !
You just need to connect the adapter to the power supply.
Just tested it with a HDMI videoprojector.
Powerpoint presentation displayed full screen.
Video file as well.
No lag at all.
Didn't check if audio was routed through HDMI (the videoprojector I used doesn't support it).

I can confirm that audio works. Anything you can see or hear on the phone goes to the TV.
I get video but no audio but that might be because of my audio setup.
I have tried it as well with a MHL adapter I bought at Monoprice and you do get audio. I have noticed sometimes it does not work though when I plug it in. I do not know why. I am wondering if the MHL adapter I bought is flaky or if Our phone is sometimes picky.
i checked the connection, video and sound work great.
No connection loss.
Connection works everytime I connect the cable.

Have you any issues with the length of your HDMI cable I found 3 feet works but 10 feet does not did not try a 6 foot as did not have 1 at the time. I think it can not be to long as it needs power from the micro USB and too long may not have enough power. Just curious on the length of your HDMI?

The cable I used was 6 feet long.
It worked great. It had no impact on video quality or sound quality.

Are you asking where to download SGH-I927UCLG9, or are you asking whether SGH-I927UCLG9 is compatible with hdmi, or what are you asking?
What makes it work?
Is the MHL functionality connected to the ROM you use, or the device? or both? I have a kitkat rom and was hoping that would make it work, but it doesn't, and didn't with the official Ice Cream Sandwich version either.
I don't have an MHL adapter, but I'd try cleaning the USB connector on the phone. The reason I say this is that my i927 would sometimes have trouble connecting to the PC by USB and often, when receiving a phone call, it'd switch to car mode, as if I had a car accessory connected.
I cleaned the connector on my phone by rubbing the contacts first with an x-acto blade, then with a piece of paper with WD40 backed by the blade and finally with another piece of paper with ethyl alcohol. Don't forget to remove the battery before trying this and be very gentle to avoid breaking the connector.
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.

that would be key. I have sent out messages to people that may know, or may be able to find out, but i have not had success.
heck, If it can be done in the terminal (turning on items) i can make a shortcut that would do it.. but i have had no success with that either.
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.

Hey there, i have tried gathering information about this subject and it seems all threads always lead to this announcement:
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:

http://forum.xda-developers.com/showthread.php?t=1811435
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. There is also a blog entry on the exact same topic and even the movement to boycott samsung accessories have stopped because of this: http://www.galaxymhl.com/
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?

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.

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

Hi all.
I've searched for similar questions and can't find anything that gives me an answer... so here goes.
Model number: GT-N7100 (Samsung Galaxy Note 2)
Android version: 4.1.1
Modifications: None.
Problem:
- Connect MHL cable to phone.
- Connect power
- Connect HDMI to tv & MHL
- Phone pops up a message on screen advising that HDMI connection has been made.
- No output from phone to tv.
I tried originally with the wrong MHL cable designed for a Galaxy S2 (established this thanks to a post I found on here, thanks). Then replaced with one designed for the S3 which should (according to what i read) also work with the Note2.
Am I missing something here?
The cable used was from Amazon and is not a samsung original part. But before spending more money to get the samsung part i want to be sure i exhausted all options with the cheaper alternative.
Thanks in advance for any help anyone can give.

I bought a 'generic' adapter at first, did not work. Ended up going with the Samsung adapter...worked fine...
make sure yr MHL cable/adaptor is compatible for note2/s3, they use different pins with older model
Hi all.
Thanks for the replies. [will do the whole thanks button thing in a minute].
I threw the adapter in a drawer for the weekend and pulled it back out this morning to have another crack at it.
Its the cheap n nasty adapter that is at fault. I shoved the connector into the bottom of the phone really hard this time, and instead of black, the tv screen went green. All green. A bit of jiggling later and i had phone output on the tv, but its a very sketchy connection and a slight knock loses the connection, even though the phone still thinks the cable is connected still.
Only problem then is that there is no audio coming through the tv. All phone settings suggest there should be.
So i went upstairs to try on another tv, and it works perfectly with video and audio (once the cable is rammed home good and hard).
Problem solved. For now, it will do. But I will at some point be investing in the genuine samsung part that should do the job properly. And a new TV for the living room ~ current one is old and was a budget model at the time, so you can imagine how bad it is by todays standards.

i'm on android revolution with perseus kernel... which is just a modded stockrom.
i have not made a samsung account so i don't have any of the samung specific apps activated... could this be the problem?
do you need to have that sharecast or whatever to be activated first in order to get the TV out functionality?
I bought Samsung MHL adapter last month for HTC One X and it works fine even without connect the phone to charging.
I just tried that to my new Note 2 and it doesn't work at all.. already try to charge the phone still not showing anything not even a notification saying my note2 connected to the hdmi...

phone then gives me the 'hdmi adapter connected' message and then the monitor goes into energy saving mode...
i guess my adapter is faulty.... it is supposedly a genuine brand new samsung adapter but i got it from ebay hongkong or china or whatever... so... well... you know..
i think i will order the wireless all-share hub in stead...
Are you rooted? I've read that hml doesn't work if you are.
Edit: I should have read the rest of the thread. Looks like you solved the problem.

well yeah... if getting a wireless allshare cast hub instead for 80 bucks is a solution.. then yes.. i guess it's solved..
by the way,
yes.. i have root.. where did you read that a rooted phone prevents the MHL adapter from properly working?
do you have a link or something?
in that case i could still try to persuade the Android Revolution HD Rom developer to look into the issue...

Try it using the 5V - 2A charger, i have read, somewhere i forgot, that 2A is a must for being able to use MHL.
I can't say if it is true or not, i'm atill waiting all stuff be delivered (All-share cast hub, MHL adapter, Smart Dock, etc).
Good luck
It seems like the china products r all faulty

For me the MHL cable worked well with easy disconnections (any minimal movement). But I used it with the bloutooh mouse and so I didn't feel so much the issue.
Now the note 2 doesn't reveal the cable. I plug it in and nothing happens.
I don't remember if I changed ROM before the issue but it's sure I always had a custom ROM.
Can be a ROM problem?
I will try the MHL cable with my father's s3 and let you know if is a cable issue.
EDIT:
SORRY GUYS, IS A CAVE PROBLEM. ITS DEAD
I have rooted my device also. Come to think of it, this might just be the issue. Rooted with exynosabuse gonna try to unroot and see if it works. Still want it to work with root though because i use the sixaxis to play games..
Once u unrrot your note 2 did it work with the mhl cable

Just curious if anyone has gotten the keyboard and mouse working on a lapdock with the Note 2. The HDMI works perfectly, but the keyboard and mouse don't work. I don't know if it is possible, but it would be great if someone knows how to make this happen.
Here's a picture of my set up. Everything is connected so it *should* work. I'm thinking that it is a driver issue.
(The lapdock keyboard & mouse work great with Ubuntu 12.04, & Windows 7, & Raspberry Pi (Raspian), so I know that my connections are fine.)
Thanks!
Hmm, guess I'll be able to answer my own question after a bit of research. It seems that the Note 2 (like the S3) can't provide MHL & OTG at the same time.
Not sure if there is a way around this. I wonder if Samsung's SmartDock works, but I don't want to spend $100 to find out.
I'm increasingly interested in trying just this, smart dock + lapdock. Hard to imagine that it wouldn't work, but I wouldn't mind confirmation if anyone has tried it. The impressive low prices on lapdocks in the secondary market kinda offsets (and also kinda shames) the ridiculously overpriced smart dock.
I wonder if the lapdock's battery can provide as much power as the smart dock needs or if I'd have to have an external battery too.

the lap dock should provide 1 amp which is what the atrix needed and the chargers it came with. the s3 has a smart dock and it too only has 1 amp chargers...
plus I don't see the smart dock pulling more than 200mA it has to provide the s3 with at least 750 mA for the charge to survive mhl.
regardless amp drain in android devices is adaptive. even if the dock needs a full 800mA the phone will try to survive with the rest draining battery of course but working none the less just like trying to charge our 2A monster with a Bluetooth 150mA charger. it will try but at best slow down the discharge

I don't know if an MHL adapter will supply both HDMI and OTG at the same time but I know the phone is capable of it because this is how the Samsung Smart Doc works. 3 USB ports with HDMI out.

I got it working. I have a Raspberry Pi that connects to the lapdock perfectly so I picked up the overpriced Samsung SmartDock and used the same cords that I'm using with the Raspberry Pi and it works pretty well.
Here's the info:

Here's some apps that make the lapdock work better with the Note 2:
Screen Standby - Need Root for this one.
Set Orientation
External Keyboard Helper

Hi I have got an S3 MHL(11pin) HDMI cable. I have tested HDMI & OTG simultaneously.
http://forum.xda-developers.com/showthread.php?t=1953061&page=7
It is working perfectly with my 24inch LED monitor and a USB hub containing 2 pen drives and one wireless keyboard & mouse
Now the next move i got atrix lapdock and try to connect the HDMI out from mobile to Lapdock (with necessary adopters) but i am getting only green screen.
Lapdock is working with other HDMI sources....
Any idea on how to get my note 2 HDMI working in my lapdock?...

I've never gotten a green screen so I have no idea. And, you already did the basic troubleshooting. Are you using the Smartdock or something different? If you aren't using the Smartdock, maybe pick one up to see if it works. If it doesn't fix the problem, you can always return the Smartdock.

Based on what you are saying, it sounds like the issue is between your lapdock & MHL cable. Like I said in my previous post, I'd pick up a Samsung SmartDock and see if it works. Just make sure that yo buy from somewhere that you can easily return it in case it doesn't work.

Dear wilbr,
Thanks for the reply.
Do you use the original samsung MHL cable?...
I am using Chinese version of MHL.
HDMI troubleshooting guide says the below....
The green screen problem could be due to HDCP non compliance or syncing problem..
anything to do with HDCP and chinese cable?...
I am trying to get an samsung official MHL or a smart dock to try out. (here in india smart dock is still not avaiable). My once route to get it is through china...

Hi refer my link posted in my earlier reply... it is easy to get the OTG simultaneously with HDMI....
For me i have connected both HDMI and USB together with lap dock.
MY lapdock keyboard and mouse are working fine and i can see it with note 2 screen....
USB port is working fine with 2 pendrives attached......
The only problem is not able to get the screen in lap dock ....only green screen...
update....
Tried with S4. HDMI detected but blank screen.
When playing video once cable is connected S4 screen goes blank but still video is running but lapdock is blank....
Team,
I have updated Android 4.3 + rooted hoping that it should work with lapdock... Still no luck.. still getting green screen.
Any help or update?.
wilbr,
Whats your android version?
Is it rooted or stock rom?...
If you are using Aosp, mhl doesn't work with Aosp.

I've already got a Bluetooth keyboard and mouse. I'm gonna order a MicroUSB to HDMI adapter and go that route. It'll be cheaper and less to carry. When I travel I'll just be able to plug into the hotel TV and go wild!
There's a YouTube video of someone demonstrating it, just search YouTube for "Samsung Note 2 Mobile Desktop with a Bluetooth keyboard mouse"

i had a similar problem, its was a shotty solder job on the "Budget adapter" (HDMI PINS). i took it apart and cleaned it, works perfectly now.
Plug your phone in, WAIT 5 SECONDS, Then lift up.....If you still have a problem, push F11 on the Lapdock... that manual cycles the resolution modes...at least thats what the manual says....
As far as the USB key board goes, im currently working a solution.... you have to power the MHL THROUGH THE DOCKS usb port using a donated USB cable with the end cut, solder it in directly on the board of the adapter itself, then make a micro usb extension that has the power wires cut and D- D+ reversed... I have a motorola ATRIX and im looking at the board, it looks like they have been reversed....ill post up some pics if i find this to be true.
---------- Post added at 03:37 AM ---------- Previous post was at 03:21 AM ----------
Also, sorry to bring up and old post, but I have a reason to believe that the ZOOM bluetooth keyboard uses the same 30 pin connector thats inside the lapdock (connects everything together) all the connectors are the same, except on the ZOOM the other end is a BLUETOOTH module...this would solve the whole issue... im about to get one on ebay. Ill report back in a few days.
I WILL NOT LET THIS THING BEAT ME
