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

Re: diy smart dock for galaxy s3
Hi. Thanks for reviewing I am using us galaxy s3 and just the stock touch wiz rom android 4.1.1.
And I received my mhl adapter. But when I am connecting it the tv screen going all black. Any suggestion about that?

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

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.

I just found out that the Perseus Alpha kernel is supposed to support this. If you're not afraid to use custom ROMs/kernels, that might be a nice kernel to flash onto the phone and keep it updated while retaining out beloved OTG+charge mode. I'll check it out today and see if it's what it's supposed to be.
