[Q] Tab dock HDMI no sound please help

Hi to all
I had recieved the dock and a good HDMI cable.
I tested in a Toshiba 37WL66Z, perfect video, but no sound, ( In the same tv I have connected my laptop and I have sound ), then I thought that it was the dock or the cable, so I tried this in a second tv I have Toshiba 32AV500P, two years newer that the first, sound ok in both HDMI inputs.( so cable and dock are OK ).
What is going on?, I had searched the net alot, but I have not found a solution, I have read that there are people having the same problem with me, concerning the dock.
Can I do something? is there are different protocolls, that the devices communicate each other in HDMI connections?
Can I made an upgrade or something else?
Thanks in advance

I think the compatibility is not a 100%. I had some troubles when I hooked my Tab. It's unbelievable that there is little to no information about the dock to find while searching on Google! (Troubleshooting)

Yes you are right no info, I had searched everywhere, the tab is a new model, perhaps in the future?, very stange though.
Perhaps the compability problem will be solved with a firmare upgrade?
I cannot found a link to ask Samsung Korea directly to check this matter, because a lot af us have the same issue.
If anyone knows a link to them?

I connected my dock, the tab makes a connected sound, but the tv doesn't recognize the dock, so no sound or video.

Ah. that's exactly the problem I had. This is the routine that usually resolves it.
1. Reboot Tab for a fresh start
2. Hook up the dock to power. (Apparently this is required)
3. Dock the tab.
4. Make sure it shows as "charging".
5. Plugin the HDMI cable. (make sure you don't move the dock too much! the connection is crappy and very easily loosened)

Thank you friend. I suspected I would need the power cable. I got one off ebay yesterday.
You have to add #6 to the steps: hold tongue out to the left side at a 30 degree angle. ;^)

[Q] MHL/USB OTG issue

Hi guys, picked up a smart dock over the weekend, gonna try a new project where I get rid of my PC and use my phone for everything, and see how it goes.
Only issue I have is that when connecting the Note 3 to the dock the screen doesn't switch off, and because its only MHL 1.0 it won't charge the phone quicker than it discharges. I got the smart dock after watching a youtube video where the guys screen goes off when the MHL is connected and he says that some do, some don't and he can't find out why or what causes it.
I did find an app that switches the screen off when using MHL but it needs root and my device is only a couple weeks old and I have no insurance, so not ready to trip knox and void my warranty just yet, although if there was a custom rom that handled docking better than stock I probably would just insure it and go for it.
Also, anyone found a dock with MHL 2.0 and USB OTG? Could only find MHL 1.0 when I was looking (want 1080p goodness really lol, MHL 1.0 only seems to go to 720p).
Thanks in advance

[Q] Need help recovering data from phone with broken Screen

Hey guys!
I've been looking around for help on this one but I've come up short.
I've got a Note 3 and I've killed the LCD. the phone still works can hear it working etc.
I need to backup a game (clash of clans... ). To do this, normally i'd link it to my google account, and then sync it to my new phone (another note 3).
However I cant get access.,.. And Keis will backup my apps but wont let me install them on any phone other than the original!
I saw there was a prog called Android Connect, however my phone didn't have USB debugging enabled. And i'm far too noivice to compile a kernel to enable it.
Does anyone have any suggestions? I was thinking a HDMI MHL2.0 cable to get the screen onto the TV, but i'd still need to control it somehow, and the usb port would be taken up by the hdmi adapter so cant plug in a OTG cable and a usb mouse!.
I've tried a MHL1.2 cable and it wont work., but I've found on ebay, mhl1.2 adapters with USB ports, but none that support MHL2.0..
Such a predicament! any help would be GREATLY appreciated. I've invested a lot of time (and admittedly money) into this game and i'd hate to waste it!
Thanks
Sam

I'm in a similar situation. My girlfriend just got a S5 Active a few weeks ago and has managed to break the screen already, and they say guys are hard on stuff. Screen will not come on at all and has a pattern lock. Is there any other way to get into the phone to backup files? Kies would be fine in my case but I can't unlock to use it. Since it is new I hadn't had a chance to set up Samsung find my mobile or Android device manager. Help us both please!

Is your phone rooted?

Hmm looks like this thread died

Nah phone is pretty stock... I have an Sview case so it unlocks the phone for me...
Have ordered an MHL2.0 cable so should be able to see the screen, but still no idea on control

Disregard - didn't see you had not enabled adb.

Unfortunately I don't think I have developer options enabled. Which is causing this predicament.:crying:

Ok. I'm stupid.
Google sidesync. Download and install pc application. Then go to Google Play store on your pc and find sidesync and click install, select your device and let it install remotely (wait about 3-5 min). Reboot your device, launch sidesync on your pc and connect your device via usb. Select usb in pc app.
If all goes well, you'll have full control and phone screen on your pc.

Just tried this with my new Note 3, and you have to run the app on the phone before you can mirror...
Dammit.... so close!
Thanks for the suggestion! feel like im getting somewhere

Argh. I din't recall having to run it first... but yes, progress is always good!
Another option is the Samsung media dock, you can use it to get mhl and usb kb/mouse at the same time.

OTG Simultaneous Charging

Hey everyone I'm doing a car install of a galaxy tab a 7.0 and I have a joycon usb controller and flash drive I need plugged in to a powered otg hub I have. Everything works great but my hub only has a switch that goes between charge OR otg not both. Is there a kernel or custom otg cable someone can guide me to to make this possible?
Thanks!

Hi there,
Ditto for me. Have it working on Nexus 7 2013 and hoping to do the same on the Tab A (SM-T285). How far have you got? I'm about to setup a breadboard with a pot on pins 4 + 5 as a standard 100k doesn't seem to do it.

OTG simultaneous charging
Hi
I have the same requirement, apparently one needs a custom kernel where this is enabled. Have anyone made progress on this ?

Dang, saw this thread and hoped for more information. I am testing out an SM-P580 to replace my Nexus 7 (2012) and need to see if OTG and charging work together. I am hoping to find some time later this week to connect it up to the car and see what works and what does not. The biggest headache is the charger port is reversed compared to the port on the Nexus 7, so currently, I cannot see the screen to test anything. Hoping that OTG + Charging will work, because at that point then things (hopefully) get easier and I just need to fabricate mounting the tablet in the dash.
Fitting a 10" tablet while making it look at least semi stock is not going to be the easiest thing in the world, so I am hopeful of getting everything working before starting to tear my car apart.

Did you find a solution? Which device did you use instead of Nexus 7?

Nothing yet, the Samsung I have did not work with OTG + charging and I did not want to pay $50 for an adapter that has so so reviews at best. At the moment I am getting set to try an LG G-Pad 8.0, which I am fairly confident will work as it has 2 USB ports, a full sized and a micro. The only problems I can see with this are that the USB ports are on opposite ends of the device, which might make it difficult to actually integrate into my dash, I am debating removing the rear cover and seeing if I can relocate the full size USB port or both to plug into the back instead of the top/bottom. The other problem is, for this particular model at least, finding any updated ROM's / root is proving difficult. It's an LG UK-495, would be cool to find some ROM's and possible SIM unlock it as well, I could the put a Google Fi chip in there and use it for calls right from the dash.

MXQ PRO 4K TV BOX - No remote and No Display

Hi I need some help please , I recieved the tv box from a friend with no remote. I plug in adaptor as well as usb to pc to power it up. There is blue light on tv box but no display on hdmi or av input. Any suggestions on how to switch it on or what to do.

It may be possible to control it using a usb keyboard and mouse if you could see the picture and it has the correct drivers. The picture thing sounds like the biggest problem, I would suggest trying different HDMI cables and tv settings. This is highly unlikely, but if by any chance your friend turned on usb debugging before the picture stopped working, there is a tool called scrcpy that can be used with adb that allows you to view your screen on your computer. It’s quite possible that the thing has broken itself, there’s a lot of reviews online about Android TV boxes spontaneously breaking after only a few months of use, sometimes less than that.
