Finally made one

The USB hub is by Gearhead model uh 4000 the uh5000 according to research online is the same thing with an included power supply. I got it from Fred's for $10 and wired the 5 to 11 pin the same as newcomer to it's mini USB cable. No power supply, but the cool thing about it is it supports a power supply out of the pack, if you have one. The hub requires a power source to function either connected to the MHL adapter, a power supply for the hub, or to the 5 to 11 pin adapter with a micro USB charger. The phone will not power it .I bought 100 resistors for $7.00 us on eBay. I soldered in an 0805 "4022" 40.2k ohm resistor directly to where the original resistor was removed from. The wires wrap through holes in the board to keep them from pulling loose. I wrapped it with saran wrap to stabilize the cable and protect the board, for the time being, since the original housing is too big with the case I'm using. I plan on attempting this with the official s3 MHL adapter and instead of two cables using one then housing them inside a stand. Something that will look a little more professional. I am running the latest version of synergy rom 4.1.2 on their ziggy kernel and OTG + charging still works as well as this dock. Plus multi windows and floating multi windows : Synergy-S3_19Apr13_1622_r484. Much props team synergy! Only rom for US s3 (one rom all us carriers) supporting multi view and exclusive floating windows.

I have a similar cable pictured above mine has a 5 pin micro USB and requires a 5 to 11 pin adapter. The USB on it is for a power supply. This could be a charging block, and yes even a PC or T.V. The other cable is an OTG + charging cable. The OTG +charging cable has a 5 pin male micro USB, and a female micro USB port but only VCC and GRND are connected in the female. I read ,in an article on making one, connecting data causes the cable to cease functioning. If it is an 11 pin micro USB on the MHL cable you could open the micro USB casing and replace the resistor with the 40.2k ohm required, and then solder an USB female for your OTG needs creating what you are looking for. We are making these because nothing stock is capable of piggy backing together to achieve the same effect. Unless you buy the $100 Samsung dock which I can't confirm works on certain variants of the S3, but will definitely work on your Note II. Hope I have answered your question well enough.
[Galaxy S III Accessories] voyager20021:
I have exactly the same 11 pin MHL cable and i will try to modify it into a smart dock. But i didn't find a 40.2 k resistor so it will get a bit nasty with normal sized 39+1.2 k resistors.
[Galaxy S III Accessories] voyager20021:
I finally had the time to take apart the 11 pin end. And this this how it looks. The resistor is 1k.

I think i only need to solder the data+ and data- extensions to the actual contacts and 5v and ground extensions to the already soldered contacts. Sense will go to the resistor left end. This will probably be more easy to solder.

Now i need to prepare a thin tip for my soldering iron and find the time to do the job. Or maybe i'll just go to a local service center and ask them to do it. I honestly don't trust my soldering skills and this is not an easy job if you don't have a good soldering iron. The one i have is not suited for such delicate soldering.
[Galaxy S III Accessories] Toxic Ninja:
search ebay for 40.2k resistor the ones I purchased are there for 6.95 and they have 1% through hole resistors too but the smd 0805 resistors I have are .1% also 100 for 7 bucks is a good deal especially if you want to make more for friends and family. :cyclops:
[Galaxy S III Accessories] voyager20021:
I think the smd is too big. I'll try with through hole ones via extensions and see if it works first.

Dunno about the 1k original resistor though. It seems different from the values provided on forums for dock or car modes.
[Galaxy S III Accessories] Toxic Ninja:
the 1k is the same one I removed from the 5 to 11 adapter. the resistors were a little large for me but I soldered it to the 4 pin first then took an exacto knife and scraped to copper for ground I even angled it a bit. then liberally fluxed it and soldered
[Galaxy S III Accessories] Sandman333:
I also removed a 1K from my 5 to 11 adapter. Instead of a 40.2K part I used a 39K and a 1.2K. I believe mine were 0603 size, but I ended up soldering them to the board like a teepee.

[Galaxy S III Accessories] HMkX2:
So I just built one of these using this pinout: Post 29

Looks a bit rough, but works on CleanRom 6 (3/7/2013 4.1.2) on a SCH-i535 Verizon Galaxy S3. However, it the USB-OTG portion does not work on a recent CM10.1 after a clean flash (Mastamoon nightly 20130418) (4.2.2).

Important note, on CM10.1 MHL and USB-OTG don't work

simultaneously

(40.2k "smartdock" code in kernel). Also, a plain OTG cable (that worked on the Cleanrom device) caused "Settings" to ForceClose when I plugged in a USB keyboard, and the MHL adapter (that works on the Cleanrom device) caused the phone to lock landscape mode but not display anything onscreen until I clean-flashed.

They need to fix the missing-smartdock-kernel-code problem with CM10.1 before I can test it again.
[Galaxy S III Accessories] voyager20021:
So, i finished the soldering on 11 pin mhl cable today. I used 2 resistors, one 1.2 ko an the other 39 ko. Problem is the last one is actually 38.7 ko so i'm short .3 ko which makes a total of 39.9 ko. The OTG USB extension doesn't work. Does the value have to be exactly 40.2? Is this the cause?

I also just got the software update on my Note 2 to stock DMC3. Could this be a problem too? Anyone with this sw version did the dock cable using this method and works?

Introducing my new lil' gadget in all its glory :The Ambered Dock

This Item is named The Ambered Dock (T.A.D for short) in remembrance of the best TV show ever in my opinion FRINGE. Those of you who were fans know what I'm talking about.

I took an official Samsung 11 Pin MHL adapter, and took it out of the case. I proceeded to de-solder the wires from the micro USB end, applied the 40.2k ohm resistor as well, de-soldered the wires from the adapter, and removed the micro USB female power port . (Used the pictures below to remember the wiring order.) Then I gutted my UH4000 Fred's USB hub; I cut the housing off of the mini USB hookup, and bent the pins up for direct soldering since my case wasn't large enough to accommodate the micro USB to be plugged in. I then soldered flat cat-5 cable to the micro USB, as was original, plus the two (5 pin) data wires.Then I soldered the other end of my cable to the MHL adapter and the USB hub. I spliced in the female micro USB port (5v in) with two wires so I could mount it into my dock, where I wanted it. I then connected the OTG data wires to the hub's data pins and spliced the power in with the power in port. I then soldered all splices. My case was made from a Wal-Mart mini clipboard (cut, bent and, welded using an old soldering iron). I Fit everything into the case made marks, cut holes, checked for alignment, and made minor adjustments. I then hot glued everything into place after checking that the device actually worked. I finished by hot gluing everything shut. Due to the delicacy of components and wires, I hot glue everything as soon as I solder and check connections. I even use it on wire splices (it acts insulator and support) because I'm hard on things and will tear something up ~lol~. Oh yeah! I also have a place for a 5v dc adapter to power the USB hub so some of the juice actually makes it to the phone. The phone doesn't charge much, without it, but seems to hold fairly steady. (This is running MHL and a mouse/keyboard combo wireless dongle.

MHL adapter $7.00 eBay

100x 40.2K ohm 0805 SMD resistors. $0.07 eBay

3' flat cat-5 cable $5.00 Wal-Mart

Mini Acrylic Clip-Board $3.00. Wal-Mart

uh 4000 USB hub $10.00 Fred's

Not Paying Sammy to do it for $100.00 $$PRICELESS$$

Sent from new Ambered Dock using wireless keyboard mouse combo.

Oh Yeah! I got a free app,Screen Standby, for rooted phones that kills the backlight without putting the device to sleep. This should keep heat down and maybe let it charge while using MHL. I'll keep you posted on that.

Nice job. What ROM do you have? Are you rooted stock/custom ROM?
[Galaxy S III Accessories] Toxic Ninja:
I am rooted on Synergy rom current version r484 (the best out there IMHO) only on S3. It brings multi-view to the S3 on all US Variants, and I believe Canadian as well 4.1.2 The only rom stock or others included that brings multi-view with floating windows.

shout out to newcomer

Thanks for the ground work. Never could have done it without you. Now I have The Ambered Dock and the more easily "on the move version too. All aid and done it is still cheaper than one smart dock from Samsung.

Will this work on note 2 (n7100) omega rom-redpill kernel?
[Galaxy S III Accessories] gronimo21:
wouldnt it have been easier to buy this
[Galaxy S III Accessories] frotna:
I made diagram of this connector/cable.

Can someone confirm that it is correct.

Thank you...
[Galaxy S III Accessories] frotna:
Can someone also confirm that combination that i draw can be made...

Thank you...
[Galaxy S III Accessories] its.mahmud:
Everything looks fine. Only usb otg part you connected sense also in the port. Usb female port will be connected there so only 4 wire will go there ( vcc,d+ ,d-,and ground ) and sense will be connected to ground before it goes to usb
[Galaxy S III Accessories] Toxic Ninja:
Doesn't have 4 USB ports, my phone only gets landscape if on its side (without buying force rotation) and I dont think that dock does MHL or has 11 pin micro usb. And My total parts list is about $25 us how much extra to get the dock and mod it.

---------- Post added at 10:51 PM ---------- Previous post was at 10:36 PM ----------

In my post a couple pages back I have a picture showing what you are trying to achieve. Except my cable has a mini usb male connecting the hub rather than a single usb port wich connects to a hub. I did this simply because my hub came with the wire. And to cut out superfluous connec to ions.
[Galaxy S III Accessories] frotna:
Thanks.

I hope this time is ok...
[Galaxy S III Accessories] frotna:
Thanks.

I will try to make exactly the same combo as in your picture cause i have the same MHL cable and the same USB HUB...
[Galaxy S III Accessories] its.mahmud:
Everything looks ok this time :)
[Galaxy S III Accessories] syfxever:
Someone who make it work, please please specify wich rom you are using and where to get it. I really tired of trying more than 10 roms and none of them seems to work for. For make it simple, I took a 5 pins micro usb connector and put a 40.2k resistor on pins 4 and 5 but none of the roms I tried reconized it.

Thanks in advanced.

Fernando
[Galaxy S III Accessories] its.mahmud:
I was using stock 4.1.1 and other ppl told about different rooms in this thread. You need to read all carefully
[Galaxy S III Accessories] its.mahmud:
I modified my cable little more and it worked with s4 . I am hoping it will work with note2 and s3 4.1.2 also

[MENTION=5117135]necomer[/MENTION]

You need to short the +d and-d for 500ms so smartdock mod can be detected on 4.1.2 ?

In my case i could see the light on my memstick flash for a fraction of a sec and then nothing. Is this the cause? Sammy did it again?
[Galaxy S III Accessories] syfxever:
Hi voyager20021, I was using 4.1.2 and tried to make the galaxy s3 to detect when I was putting a 40.2K resistor. Also tried on 4.1.1 with a lot of rom. Nothing happened but it was my fault because I wasn't using power. Yesterday I connect power and the resistor to this board:

https://www.sparkfun.com/products/10031

The galaxy made 2 sounds: one for charging event and other just like I wasing connecting de desk dock. Regrettably I'm out of 5 to 11 pin micro usb adapter so I ordered 2 to continue the test.I don't have the catlog o dmseg.

This was wrote on the first post but I read a lot of info so I forgot it.
[Galaxy S III Accessories] voyager20021:
I think 4.1.2 roms need something more than just the resistor. Necomer seemed to have found out what but no answer from him.
[Galaxy S III Accessories] its.mahmud:
Hey sorry I didn't reply your post on time. Yeah. I changed resistor there. But its nt working always. And phone start to heat up. I used 64.9k resistor.. everything is same as the last connector and only the resistor is changed :)

i bought the smart dock. took it apart checked the resistord. 40.2k resistor is used between pin 4 and pin 5. i couldnt find any resistor in data+ and data-

i PMed you befor. you maybe didnt check [MENTION=4055543]voyager20021[/MENTION]
[Galaxy S III Accessories] voyager20021:
Yup, i just saw your PM. Sorry, i didn't check.

So if no change in resistor value, how come not working on 4.1.2? Kernel is enabled (i use Perseus) so is it the stock ROM? I tryed some custom ROMs also and no go.
[Galaxy S III Accessories] its.mahmud:
Thats what I am wondering too. Did you try the 64.9k resistor? I got it worked with that resistor. I ordered 100 of them. If you want some of these, pm me

if you think ii helped you. Don't forget to hit that magic button ;)
[Galaxy S III Accessories] voyager20021:
Nope, did not try 64.9K. Couldn't find even the exact 40.2K but I was close enough. Hard to find those exact values in Romania. I PMed AndreiLux, Perseus author, trying to see if we could a kernel mod to allow some tolerance to the 40.2K resistor like from 39 to 41k so we could use some common through hole resistors, but it seems to be a bit more complicated than it looks.
[Galaxy S III Accessories] its.mahmud:
I have ordered 100 of each 40.2k and the 64.9k resistor and I don't need all of them.. if you want I can give you some of each. You just have to give me the shipping cost. I don't want those resistors go wasted :)

No go to adapt kernel. Just got the answer from AndreiLux.

A few issues with my ambered dock. I tried to watch a full movie today via my s3 and the dock, for the first time, but after about 15 minutes it started to flick off on the television screen and back on intermediately. I figured with the power draw maybe it was the USB hub. I plugged in a 5v 500 ma power supply but with the same results. I gave two thoughts. This may be a result of the rom I use and more to the point its kernel, or the knock off "Samsung" mhl 11pin I got off ebay. I can tell it is a knock off by the poor soldering job. It starts flickering maybe once every ten then exponentialy more frequent. Maybe the mhl components are over heading with use. I just don't know and need another phone, preferably stock to test before I start replacing hardware in the dock. has anyone experienced similar problems? Anyone have any ideas?

I had a dock working for my t 999 running 4.1.1. Mouse, keyboard, hdmi, and charging was working.

After the update to 4.1.2 the Dock doesn't work anymore.

I just tried changing the 40.2 K resistor to 64.9 K and it shows up now the dock is connected but will not output the video. It does not say HDMI connected. Mouse and keyboard work.
[Galaxy S III Accessories] zanzee:
You need more than a 500ma psu, if your running a hub and any peripherals I would start with 1 amp minimum. Just charging the sgs3 will pull 700+mah. Grab the biggest 5vdc charger you can, I'd go with about 2 amps just to be safe.

Follow the diagram and use 64.9k that will activate the smart dock mode. :)

[Galaxy S III Accessories] athlonxp2300:
What dock mode does it do? Like I said a couple of posts back. 64.9k put it in a dock mode but not hdmi out. Only the usb worked and I'm not sure if it was trying to output audio or something, but this same dock worked fine before the 4.1.2 update.
[Galaxy S III Accessories] its.mahmud:
Well.... 64.9k resistor is giving hdmi out in my galaxy s4 4.2.2 I didn't try that in any 4.1.2
[Galaxy S III Accessories] jwenz723:
I am trying to make sense of what you made here. Is the attached diagram correct?

Also, if I don't want to use hdmi with my setup, can I just connect a powered usb cable to the female usb where the mhl/hdmi adaptor is going in the attached diagram? My goal is to just get power to my phone and have a few female usb connections as well.
[Galaxy S III Accessories] its.mahmud:
Lol you said you are trying to make sense of what I made? So my work dosnt really make sense??

Did you really take a look in my diagram?

Take a look. Just make it like that. Then if you want to use mhl , use it or els dnt.

Or if you dnt want mhl a all just follow my diagram and just dnt connect the 3 wire for mhl function.

Its that easy. Dnt know why that dnt make any sense to you that you have to try to make sense of it.

Good luck

In 4.1.2 still the 40.2 works. Stock rom with perseus kernel. Tried 64.9 and no hdmi out.

It seems the only problem to make it work is getting resistors as accurate as possible, with very little tolerance.

Thanks again necomer, my phone is alive!

Now i just have to figure out a dock for it.:)
[Galaxy S III Accessories] athlonxp2300:
What phone model was this? GS3 international?

Both my wife's and my T-Mobile USA T-999 worked fine with my homemade dock with a 40.2k resistor when on stock 4.1.1

They both broke with the update to 4.1.2
[Galaxy S III Accessories] voyager20021:
Well, in the morning when i tried it was broken again. In fact, the only time it worked at first it made a loop connect/disconnect sound until I connected the keyboard dongle. At that point the notification sound stopped and the phone saw my keyboard as usb mouse and it worked. No luck again since then. Sometimes when tested after it even lost hdmi connection a few times. I can't figure out what is the problem as nothing was changed. So I guess the mod is not stable yet. Also my phone was softbricked at some point so I had to use the backup. Now I am on stock 4.1.2 DMC3 rooted and I'll try this way when I have the time.

---------- Post added at 10:19 AM ---------- Previous post was at 10:11 AM ----------

I'm on NOTE2 international model. No difference though. Necomer can confirm.
[Galaxy S III Accessories] athlonxp2300:
There is a difference for that and the gs3

Especially usa gs3 vs international gs3.
[Galaxy S III Accessories] voyager20021:
I also had that flicker at some point. But only mhl was on, no otg. And it seems to me, or the phone doesn't charge with this cable? I think it looses power wile connected.
[Galaxy S III Accessories] athlonxp2300:
When my dock was working I ran otg to a wireless dongle (no hub) and mhl to hdmi at the same time.

I was using at least a 1amp charger to power it.

wireless mouse and keyboard via the dongle, hdmi out to tv and device charging all worked at the same time.

I didn't use it enough to remember if my battery level was higher after I was done using it than when I started.
[Galaxy S III Accessories] voyager20021:
New tests on stock rom and kernel

Sense and ground shorted (no resistor)-otg only (this is the way to make otg from any usb)

40.2k resistor-mhl only

64.9k resistor-otg only

And I think it's safe to assume that using the original 1k resistor will result mhl only although nobody tested

So unless someone can figure out dock script from stock rom and what changed from 4.1.1 to 4.1.2 we'll never find out how this thing really works.

Another ideea would be to use a variable resistor and try to find the correct value.

If the mod works only sometimes I think we use the correct value of the resistor but maybe not the exact one? Could any tollerance of the resistor be too much? Maybe the fact that sometimes it works is because by connecting the cable we make some kind of short and get to the right value?

Any thoughts?

---------- Post added at 11:26 PM ---------- Previous post was at 11:23 PM ----------

I used original charger with mhl and wireless keyboard dongle and never got to rise battery level. Original smart dock is using the same original charger right? And it's 2 amps right?
[Galaxy S III Accessories] geekworld:
Hello

Have you any updates ?
[Galaxy S III Accessories] voyager20021:
Nope. Couldn't find the time to search and test a variable resistor. If anyone can test... All you need is a variable resistor that contains the 40.2 k value in it's range.

I only found out none of the resistors i used had the exact value of 40.2 kohm (just repaired my multimeter). The closest was 40 k. So unless i test with exactly 40.2 k i can't say the mod works or not.
