Hi,
My controller had stopped working. I think it might have gone flat. It won't turn on even after getting charged. I decided to unpair it and then re-pair it. It did not work, as it needed to be hooked into a usb cable and was flashing light rather quickley. As soon as it controller was unplugged from the usb, it won't dead again.
I have tried all the tricks on the web, but no change
Is this a battery issue?
Thanks

Hi folks.
I am looking into installing my Nexus 7 permanently in the car, needing the use of being able to charge it, and use an USB DAC at the same time.
This page promises to have an ROM that is able to do that, but I have been unable to get that to work at all. I do not want to upgrade to 4.2.x due to the known bugs, so it's 4.1.2 for me at the moment.

Using a stock ROM i am able to start/stop playback with Tasker registering "AC charge" - How do i go about this when using an OTG-Charge ROM ?
I do not want to charge the tablet when i'm not driving the car, what happens to the USB DAC when the power is cut, does it lose sync with the Nexus 7, and requires a reboot to function again?
So in short this is what I had in mind:
Ignition on -> Tasker registering AC power, starts playing music.
Ignition off -> Tasker registering power is off, pauses music, tablet go to sleep after at set amount of time.
I am realising that this may not even be possible, I can't see how the USB connection should survive, when the power is being cut, but maybe some of you more experienced guys can chime in on this subject.
I would rather not make any modifications to the tablet, but if this is neccessary to make it work, i'll have to do it (e.g. feed power directly to the battery with Li-Ion charging circuit.
Any other ideas of letting Tasker know that the car is started ? I have a bluetooth handsfree in the car, but that is connected to my iPhone, so I cannot use that as a wakeup function when that connects as Tasker do not have any "Blutooth Near" functions...
I've tried to connect 5V to the POGO pins on the side, but it won't charge the battery this way (it's enabled in the 4,2,x ROM afaik)
I've wired up my USB OTG cable like this: http://goo.gl/vqc3F
Any ideas is very welcome, as I cannot see how to do this.

I'm looking at doing the same thing but also a USB flash drive and also a Joycon EX Steering Wheel Control PC Interface via USB.
What I'm debating on doing is instead of hooking the charger to the ignition to turn on n off with he car I'm thinking about using constant power and hooking up an input on the joy on to the ignition 12V and setting the screen to come on n off with the car.
Unfortunately this means the tablet will be on the charger 24/7 but not sure how else to make sure everything reconnects as it should.
Anyone else have any ideas?

I'm planning on doing a car install with all the bells and whistles also:
Joycon Ex
USB DAC (E10 or Behringer?)
USB Hard drive
Powered USB Hub
From what I've read of other threads, some people have trouble getting the DAC to reconnect after power changes, and some don't. In general, the rule of thumb is as long as the N7 is booted with the DAC attached, you should be able to unplug (or stop powering it), and then start again. There seem to be some behavioral exceptions with this (e.g. if you don't stop audio playback before putting the tablet to sleep with tasker, when it wakes up, you may need to fiddle with it before it starts working again).
It's a long thread, but I'd recommend reading this:
rootzwiki.com/topic/30615-can-you-charge-usb-host-mode-simultaneously/page__st__140
Timur has provided multiple patches that are trying to satisfy everyone's exceptions in trying to get this working.
Hi,
Has anyone have problem on MHL kept on running and draining battery even after the cable has been unplugged from the phone?
I thought, after watching the MHL output on TV the phone battery was at 60% when I went to sleep.
I had plugged the phone to my MacBook Pro for charging but I found the phone is warm and battery level at around 40% when I woke up this morning. So, I powered it off and connected it to the charger to let it charge.
If the MHL capability does not terminate itself after using, then, how to manually terminate the MHL function without rebooting the phone?
settings - nfc - screen mirroring off.

This setting does not involve MHL/HDMI output.
Screen mirroring is used when device is used with a EZMirror device such as Tronsmart T1000 Mirror2TV Wireless HDMI display.
The question I asked involved MHL cable physically plugged into the phone.

hi ,
My experience so far with using MHLon Note 4 is ,
I have a Samsung HDTV Adapter for the Note 4 ( MHL3 ) that connects to HDMI cable and to Tv and used it a few times
and had no such issues as what you described above. I unplugged it and thats it.No battery drain afterwards and no reboots .
good luck
First: How do I get my Nexus 7 to charge from the OTG cable? I can connect USB devices to it but connecting the power cable of the Y doesn't seem to do anything.
Second: Is it possible to wake from tapping?

All other threads I've found relating to the OTG cable charging reference Timur's ROM which is no longer available. Is there another solution?
I've got a Nexus 2012 Wifi and all the hardware (USB DAC, amp, wiring, etc) to install this in my car. My last 2 hurdles before ripping the dash apart is the charging while connected to a USB hub and how to wake the tablet up. I was afraid of leaving the screen on all the time would burn it out and drain the battery. I wanted the ability to turn the tablet on without having the keys in the ignition. I guess I could forego that requirement and just have the tablet always on and only turn on in the ACC position.
For the wake I am thinking of creating a mechanical switch that activates the button. The power button on the tablet now will be concealed by the bezel once installed in the dash. There is an app that works but it doesn't really wake from sleep but rather creates a black screen that is tappable. I really wanted the thing to go to sleep and then wake with a tap.
I also wanted the newer android version, 6 or greater. I flashed with CM 7.1 and it works great save the two issues I'm having. Even if I had access to Timur's ROM it hasn't been updated since 4.something so I would want it newer anyway.
Any ideas or suggestions?
Thanks in advance.
I installed the BeanStalk 6.19 and I am now able to OTG charge and double-tap to wake device (no extra settings as it was included with the ROM).
My problem now is it seems to only want to OTG charge when I first plug in the OTG cable to the tablet. If it's charging and I turn off the power to the OTG (like disconnect the charging cable connected to the OTG) and then plug that charging cable back in it will not charge until I reconnect the OTG cable to the tablet. I wanted to hide the cable behind the bezel of the dashboard.
I was hoping to switch the power to the USB hub that is connected to the OTG charge cable with the ACC line from the ignition. This way I wouldn't be draining the battery at all when the keys are not in the ignition. It's only 12.5 watts so I guess I could leave it on all the time. It's getting cold here this time of year so I didn't want any type of extra drain on the battery when I didn't need it.
Any suggestions?
Ever since I got my Shield TV, my controller has refused to charge at all. I've had it plugged in overnight and it's still nearly dead in the morning. It keeps turning off while I'm using it, and the battery indicator shows up on the screen. I've plugged it directly into the Shield, and into a separate USB charger. Neither seem to be working. How do I fix this?
No one?
I just discovered that the controller DOES charge.... if I have it plugged into my PC. Is that normal, for it to only charge that way?
That's an odd situation for sure...but doesn't make sense...I know there is a usb setting on the shield..but idk what it does...not home or I'd look....but not charging at the wall is odd too.
I tried several different USB cables, until one finally worked, both with a wall charger and with a PC USB port. The Shield itself, does not charge it, unless I plug it into the port closest to the power supply. The other one, does not work, supposedly due to debugging being on. Haven't tested it with debugging off, though, but I'm sure it still won't work then.

I have a 2017 shield tv that when Plugged in the green case light comes on then nothing after that, no change at all on screen or to the light. No signal seems to be sent to the TV or monitor. I have several Shields and swapped things around, working cords, power supplies, working game controller, working USB keyboard etc. No fast boot can be achieved and my computer does not recognize it when it is plugged in to it. I do not know it's history.
I responded on a thread from a 2015 pro with that problem and the last responses were about the hard drive cable but this is obviously not the same or the fix for this. I couldn't find anyone posting any solutions for no hard drive. Thanks
