Resistor values

40.2K 1% resistors were working with 4.1.1 Jellybean. On upgrade to 4.1.2 I get no MHL connection and no OTG.

I tested the following resistors:

0 ohms OTG working, no MHL (this is the stock USB OTG standard connection)

1K OTG not working, MHL OK (this is the stock MHL adapter connection and was the original value in my adapter)

365K launches an alarm clock app, no OTG, no MHL

64.9K OTG working, no MHL

I also tried 28.7K, 34K, 40.2K, 49.9K. No MHL or OTG with any of these.

So they broke the Smart Dock when they updated to 4.1.2.

This is using my factory stock Samsung Galaxy S3 SCH-i535 Verizon version, not rooted. The resistors in question are between pin 4 (ID) and ground on the USB OTG connection. The adapter I use gives access to the USB OTG pins (though they are not soldered) and carries the MHL pins to a micro USB connector for the MHL side of the 11 pin connection. I soldered a powered hub to the USB OTG connections and attached a mouse to verify USB OTG host activity.

I notice the Samsung stock Smart Dock is not listed as being compatible with the S3 as it used to be. Now it says S4 and Galaxy Note II.

Don't know why they decided to change this but it sure breaks my project.
[Galaxy S III Accessories] voyager20021:
I am on Note2 and it's not working with 40k resistor. And this is a value in range of 1% tolerance.

Anyone tried flashing back 4.1.1 rom and custom kernel to eliminate SDS sindrom?
[Galaxy S III Accessories] oltechie:
Resistor Values

I had to know so I took my Galaxy S3 back to 4.1.1 and yes, it does work again with the 40.2K resistor. So this functionality was definitely broken by the update, whether intentionally to push sales to the S4 or as a bug.
[Galaxy S III Accessories] max420420:
Ok guys!! I got a good news. After I opened smart dock. I found they used only 40.2 k resistor.so I started

to try all the ways. And found a trick!! That enables both mhl and otg and charge the phone. I tested on my galaxy s4. I will make a tutorial soon.
[Galaxy S III Accessories] athlonxp2300:
When you took it back to 4.1.1 did you do just rom, or rom and kernel, or rom, kernel and modem, or firmware too?

It would be good to isolate this. Then maybe we could find out where the change was and make a fix for newer roms.
[Galaxy S III Accessories] oltechie:
Sorry, I just had the local phone repair guy do it and never asked what he did. It looks factory stock.
[Galaxy S III Accessories] voyager20021:
Nice...! Sooner than later is better! :)
[Galaxy S III Accessories] kickthefreak:
yes me too, im waiting for your tutorial, can you post it ? :good::D
[Galaxy S III Accessories] oltechie:
New wrinkle

More research on this. It is not just a matter of Jellybean 4.1.2. It is the latest update that is at fault. I have a phone that is at I535VRBMB1 that works. It shows as Android version 4.1.2. Under Software Update it shows that it was last checked for update on 5/16/2013.

Another phone at 4.1.2 shows I535VRBMF1 and it does not work with the dock. It was updated 7/3/2013.

Moral of the story - if you are using a Smart Dock or DIY version of same, don't update for a while. My guess is that this is just a bug because it breaks a Samsung stock accessory. If so the next update may fix it.
[Galaxy S III Accessories] athlonxp2300:
What kernels do each of the phones have? Screenshot of each would be great.
[Galaxy S III Accessories] oltechie:
The version shown here does not work: (no MHL, no OTG USB)

This version does work:
[Galaxy S III Accessories] athlonxp2300:
So could you try flashing the feb 14th kernel to the newer build and see if it enables the smart dock mode?
[Galaxy S III Accessories] oltechie:
Sorry, I don't have the skills to try something like that. I'm a hardware guy!
[Galaxy S III Accessories] voyager20021:
We know it's 40.2 k. Necomer opened one too and found the same. However the original smart dock works and ours doesn't on JB 4.1.2. How come?
[Galaxy S III Accessories] its.mahmud:
That id was mine. For some reason I couldn't log in my account and I had create another account to post that. Well yeah I think I found the way to work around it. Its working perfectly in my galaxy s4

But I didn't try it in any android 4.1.2 but I will give an update soon

Anything on that guide?
[Galaxy S III Accessories] voyager20021:
[MENTION=3725176]Diim[/MENTION]: good to know all you said. But we are still at the point we cannot enable smart dock mode on android 4.1.2 using 40.2 kohms resistor.

So if you have that kind of skills and can afford, open the dock and maybe you could figure out if there is any kind of sequence the connections we use in our diy smart dock should be activated. For instance, necomer told me his trick on his S4: short pins 4 and 5 with 40.2 resistor also connected than connect the phone and get otg mode. While on otg mode disconnect the wires and that will enable smart dock.

I tried that once using 11 pin adapter (S3 cable) and couldn't enable smart dock. But didn't have the time to play with the cable. I also lost my launcher settings disconnecting and reconnecting the cable a few times.

SO IF YOU TRY ANY OF THOSE HARDWARE MODES BEWARE! MAKE A BACKUP FIRST! THIS IS NOT STABLE AND MAY SOFTBRICK YOUR PHONE!

When i first tried this mode my phone was reverted to factory settings by doing the same thing (connecting/disconnecting mhl cable while the phone was on).

If anyone else can test necomer's trick please post.

And if this works (he said in his case worked every time) please help him help us by making donations to him. He bought and opened the smart dock and confirmed the resistor is still 40.2 kohms and has been trying to help us from the start.

If this mode works we need a more secure way to short/unshort the wires.
[Galaxy S III Accessories] voyager20021:
I use 11 pin mhl cable for galaxy s3 so no 11 to 5 pin adapter in my case (things should be simpler right?). See my photos here

http://xdaforums.com/showthread.php?p=40781426

I connected only one usb cable so i only have 1 usb port (no hub so no extra power should be necessary).

When connected to phone i always have mhl and no otg. So mhl is not the problem. Only once i could enable smart dock mode by pulling and reinserting many times the wireles keyboard dongle in the usb port. Dunno exactly what happened though as i couldn't reproduce that since. But once the smart dock mode was enabled that one time it was stable.

Otg mode is never on no matter if the hdmi is connected to the tv or not. This is the problem. The phone only enables otg when sensing the 40.2 resistor if it goes in smart dock mode. As i said i only could do that once, dunno how.

And when connected, the phone is always in charging mode too. In fact this is the first thing it does.

But it seems to me it doesn't charge even without the dongle connected. I'll have to test that when i have the time.

I have a Note 2. Some ppl say this could be a problem but there was no mhl cable especially designed for it as far as i know.
[Galaxy S III Accessories] yugoport:
Thank you both for the dedication, I'm also very interested in having both usb otg and mhl, but one thing catched my attention, Diim said that mhl could be powered via the hdmi cable, and that would be great to achieve.

Do you guys think we could build a cable capable of working only powered by the hdmi cable?
[Galaxy S III Accessories] voyager20021:
Gooooood news guys!

I hope it's not to early to be happy, but i think i just found a way to make it work.

I don't have the time right now to write down all the steps and i need to test some more, but if I'm right it would be so simple and easy.

I'll post as soon as i can.
[Galaxy S III Accessories] voyager20021:
It seems i won't have the time for tests this week so I'll just give you the sequence and please post your test to help improve:

1. Cable completely unplugged (i only had the dongle on usb port but it could also be connected after completing all the steps)

2. With 40.2 resistor soldered you short sense and ground before the resistor( I shorted both ends of resistor while connected)

3. Connect to phone-it will get into otg mode. KEEP SENSE AND GROUND SHORTED

4. Connect charger

5. Connect hdmi to tv - the phone keeps otg and goes into mhl mode also

So we have both otg and mhl!!!

To test:

1. Take of the 40.2 resistor and see if it works with the same routine (ground and sense shorted w/o resistor)

2. See if charging works (i think it doesn't -the smart dock mode is probably not enabled this way so we won't have charging?!)

3. Try changing routine like connect phone last so we may keep hdmi always connected to tv. I also noticed the two modes keep working even after disconnecting the power?!

Once again: do not try to work on the wires (short/unshort) while the phone is connected. Also do not connect/disconnect the phone too many times in a short interval of time, like a few seconds. You will lose settings!

This is all. Please test and report back so we can see if it works and improve.

I'm on Note 2 android 4.1.2 Perseus kernel.

[MENTION=3725176]Diim[/MENTION]: what would happen if i connect the original charger and a usb hub externally powered at the same time on our diy smart cable? Should i expect any explosions?:confused:

[T-Mobile Samsung Galaxy S II SGH-T989] Slash837:
Just got a brand new Samsung Galaxy SII T989 from T-Mobile this week, it really is a great phone, only I have a single problem.

The phone charges, it functions properly generally speaking (calls, texts, camera, wi-fi,etc...) but as soon as I connect it to my computer it freaks out.

It acts as if I were disconnecting and reconnecting the USB cable 2 times a second. I can hear the phone making the beeping sound it makes once you connect it to the USB every few seconds and in my computer (Which is running Windows 8 x64, just in case.) I can see the "Safely remove hardware symbol pop up and disappear a few times a second as well.

This is really frustrating... I love to take pictures and videos and edit them... I'd also love to copy some music over as well...

So far I've determined it can be the cable, bad drivers, or the phone itself, I just hope it's one of the first two.
[T-Mobile Samsung Galaxy S II SGH-T989] imanoobfml:
Try re installing the correct drivers or switching the usb hub. If that does not work it's most likely the usb cable, swap it for a different one and you should be fine considering you bought the phone new.
[T-Mobile Samsung Galaxy S II SGH-T989] thakrew317:
Or you got a phone with a bad motherboard which would be crazy considering its new but that kinda sounds like the problem I had
[T-Mobile Samsung Galaxy S II SGH-T989] Slash837:
Alright cool, but how does one find currently installed drivers when the device isn't plugged in?
[T-Mobile Samsung Galaxy S II SGH-T989] RealPariah:
Ok, does it get better or worse if you hold the cable with your finger when it is plugged in to the computer and phone and move it around a bit on the phone end? If so, I even got a Nexus 7 brand new from Google that the charge cable phone end was bad and would not make a good connect and I had to use a different cable and it works fine with my tablet.

If you use the same cable in your AC charger and on the computer then prolly not the cable.

It could be something in Win8 if it is trying to scan your USB port [like maybe a whacked anti-virus].

Have you tried a different USB port on your computer to see if maybe the one you were trying to use is bad itself?

If using a USB hub between your computer and the phone try removing the hub from the equation and connect directly to the computers USB port.
[T-Mobile Samsung Galaxy S II SGH-T989] Slash837:
I am using a HUB on a Razer Keyboard that I've always used BUT now that you mention it my webcam had the same problem. It wouldn't work with the HUB on the keyboard. I'll try another USB slot (My computer's other USB slots aren't very accessible which is why I've hesitated to try another slot.)

I don't use anti-virus and yes, the cable works perfectly fine on the AC USB to Power adapter it brings.
[T-Mobile Samsung Galaxy S II SGH-T989] Slash837:
I love you. It worked. It's the USB hub which doesn't allow much power to go through to the connected device. Thank yo so much.

Correction on the TITLE 4200 not 4300 sorry

The problem

Battery. it 40% in less than 12h

The set up

SgsIII stock rom

Ive been running windows 8 launcher(a week), apex launcher

Hyperion 4200 battery

Most charges are 8/9hrs

I kill most apps with holding home than the trash can.

Here what ive noticed in the last 2to 3 weeks ive been getting super crapp battery life. I was getting 1day +10hrs on moderate use

And now ive been lucky to get 12hrs on this battery. When im out at work I turn wifi off gps off and screen rotation off.

I also noticed a couple of times when I took it off charge it showed 100% then in 10min it was down to 88% and steadly dropping.

Is there a way to recalibrate the battery.
[Galaxy S III Accessories] FrankAbagnale:
I don't know if its the exact same battery you have, but I've been using this Hyperion for a month now and I'm starting to have problems with it too:

http://www.amazon.com/gp/product/B00851RT28/ref=oh_details_o04_s00_i00

For the first 3 weeks it worked totally fine, charged to 100% in a reasonable time, etc. But now it takes a REALLY long time to charge. And it only charges to 98% instead of 100. Also, the battery drains a lot faster than it did the first 3 weeks.

I'm running stock everything.

Killed all background apps to make sure that it wasnt the cause for battery drain too.

AW: [HELP]Missing the Home.apk

You could try to download nova launcher with the play store Web interface. If that won't work, open a stock rom and search for launcher2.apk or take it from a custom rom then install it with adb install.

[Nexus 7 General] bftb0:
As the above poster said, "Launcher2", not Home.

The type of things you are doing - altering things in /system - is exactly the sort of activity that you prepare for inevitable mistakes by making full Nandroid backup of your ROM ahead of time.

Didn't make a backup? Live and Learn; now you know why they are useful.

If you have a backup, save your current ROM to a full Nandroid backup, restore the good backup, and pull the launcher2 .apk and .odex files out of the /system partition from that. Then restore your borked ROM backup and put them in place into /system using ADB and the recovery, e.g.

C:\foo> adb shell

# mount /system

# mount /sdcard

# cp /sdcard/Launcher2.apk /system/app/Launcher2.apk

# cp /sdcard/Launcher2.odex /system/app/Launcher2.odex

# chmod 644 /system/app/Launcher2*

# chown root.root /system/app/Launcher2.*

# sync

# umount /system

# exit

C:\foo> adb reboot

FWIW (nakasi JOP40D 4.2.1 stock):

[Nexus 7 General] Russ77:
since its rooted, I assume you have a custom recovery flashed? if so, download your exact ROM as a flash able .zip to a computer and copy that to your tablet. reboot into recovery and dirty flash it.

or do a factory reset and a advanced restore of data only.
[Nexus 7 General] RootTheMachine:
Or you could simply flash the stock system.img in fastboot.
[Samsung Infuse 4G] b3y0ndd34th:
Sorry if this is covered somewhere I have searched and I am not having any luck.

Anyway I have an infuse, when I turn it on I can barely see the screen because the backlight causes a bunch of really close together horizontal lines. If I let the phone sit for 5-30 min most of the time it will flicker out and I can see my screen. Until the screen shuts off and I turn it back on again. I have tried various brightness levels but i am at my capacity right now I could really use some help.

The problem isn't always the entire screen, and sometimes it's worse than others I will include a couple pictures to better depict my issue.

Truly, great job on a really smooth ROM. I wiped clean fully and just installed gapps. Everything seems to work great except camera (back and front) for me. It actually is sideways preview, will take a few pictures and then it dies. Happy to see the stock swipe keyboard. Been having to flash that for a while now. As stated no backlight on hard keyboard for those who love it. Phone calls and mms worked fine for me. Loving the lockscreen and beautiful way toggles are integrated and always available. I can upload a logcat if it helps for the camera.

Side note no headphone out
[T-Mobile myTouch 4G Slide] SKAm69:
This ROM is a huge performance boost comparing to CM10. No random slowdowns. I will put together all the bugs I have found if that will help: no FFC (back camera works with scvergarhen's kernel), no headphone jack sound, clock app fcs but that might be due to no data wipe flash. And it still reboots sometimes while toggling wifi. This ROM is so great that I haven't decided yet if want to come back to CM10 because I need headphone sound and ffc would be cool for Skype. This is my night time ROM for now lol.
