[HELP] Evo only charges when off

i'm running a Gingerbread build based off of the latest nightly with stock kernel.
i've formatted my device with the formatall.zip and reloaded the ROM. i've even gone back to a stock ROM and still got the same issue. after doing this, if i plug my device up, it charges just fine while on. if i unplug the device later and plug it back up, the charging light will come on, then quickly go off and the device won't charge.
the only way i've been able to get around this is to turn it off, in which case it then charges. i get these same results whether i'm plugged into the wall or to PC.
if it were a hardware issue, wouldn't that mean it wouldn't charge at all, whether on or off?
anyone have any ideas or experience with this issue?

Same Here...
Anyone found solution yet?

My only guess would be a kernel issue or a hardware problem. Wipe your dalvik and cache and reflash your kernel. If that doesn't fix it, I do know some evo's micro usb ports go bad. I don't know if this is a symptom of that but it may be.

Thanks alot **TheSilverStig **
It was the kernel.
My phone is charging now...
Will test for a couple days and will let you know again..
For some reason www dot qap dotla/~netarchy/ is not working (Error 404)
Try http home(dot)comcast(dot)net/~evoreviews/downloads(dot)html
For now...
For me
netarchy-toastmod-4.3.1-cfs-havs-nosbc worked...
Hope that helps for you too...
Good Luck
*Happy Rooting*

[Q] OTG Charge + USB Host Plug and Unplug Timur Alternative

Hello all,
I have a nexus 7 2013 and I am looking for a kernel that supports otg plus charge. Now, I know elemental x (by flar2) and a few others have this but the ones I have found do not support hot swap, or unplug and replug without rebooting. I am pretty sure Timurs kernel supports this but he wants $36 to buy it and I would rather not spend the money without trying it out first. Specifically, I have a fixed in-car installation and a febon100 UVC video grabber to display a backup camera. When the car shuts off, the febon will be disconnected from the usb side of the nexus, and the only way to reconnect it is to reboot the tablet with power connected. Anyone have any ideas? Thanks for the help.

Ok so I figured part of it out. After the device looses and regains power, these two commands simulate the usb disconnect and reconnect and seems to work (only tried it a couple times)...
Code:
echo "2-0:1.0" > /sys/bus/usb/drivers/hub/unbind
echo "2-0:1.0" > /sys/bus/usb/drivers/hub/bind
However, I have another issue. I am using the elementalx kernel on android 4.4.4 (currently on Carbon rom but have tried stock and other roms as well with same outcome). When the tablet reboots with the otg cable connected, it does not charge when it first starts up. To charge it, I have to physically unplug and replug the cord in the nexus. Any ideas?

Just use tasker to run the commands at startup...

Does this set of command still work with lollipop? I just tried a few times and it seems to have made no difference.
Thanks in advance!

Yeah im in the same boat. Soooooo many problems with this ****ty tablet. Knew i should have installed an iPad. They said this is the 'best' of android. It's ****ing terrible. People who are thinking of installing an android into your car? A word of advise. Dont do it.

It's been almost a year any way to accomplish charging without having to physically unplug the OTG and plug it back in. Im have timurs kernel but I want to use elemental so I can use marshmallow. Timur accomplished it somehow. Someone has to know how.

It is actually trivially easy to accomplish - on any kernel - it is called Qi Wireless Charging.

Android 6.0.1 kernel Quanta-V7-Flo with 'USB Host Mode Charging'

Test results for Android 6.0.1 Stock + Kernel 'Quanta-V7-Flo' with active 'USB Host Mode Charging' and inactive 'fast charging' (N7 is only is use when its connected to the USB Power):
Ampere values checked with one of the cheap 'USB Charger Doctor Voltage Current Meter Mobile Battery Tester':
0.45 A for N7 only
0.61 A for N7 + USB Ethernet adapter
I don't use the N7 in a car setup but this should be important for such setups:
-If the USB Y cable is connected before powering on the N7, the USB device was usable in Android after startup without need for reconnecting the USB cable
-If the USB was unplugged and reconnected the device, it was usable in Android
-Important: If the N7 goes to sleep, it can't recover the USB charging and USB devices after waking. You should set the display timeout to always on, which is right for a car setup or am I'm wrong?
I'm happy! :good:

I tried quanta. It does work except for on initial boot. Have to unplug and plug it back in to charge. Then it works fine turning the key on and off for power. However it doesn't mount the OTG devices again without unplugging it and plugging it back in.
Edit: I also have another problem was at work and didn't have time to add it. But my Nexus thinks it's still charging after disconnecting it from power supply through the OTG cable. When I turn the key off it quits charging for about 1 second then switch's back to saying it's charging again and continues to say it's charging even after cycling the key on and off. Only way to fix it is to disconnect the OTG straight from the tablet and plug it back in or boot it into recovery then back to system. Has done this thru multiple roms and kernels. Only kernel it doesn't do it on is Quanta. The thing is it didn't use to do it at all no matter what rom or kernel I was using. I even went as far as to change the charging port board cause I had another one in a old junk Nexus I have and still didn't fix it.

Did you try the glitch kernel?

I've used it before but not on my current setup.

Assuming one of these kernels provides OTG + Fast Charging, what are the options for the Power-Down + Deep Sleep, then Power-Up + Wake?

Thanks for the quick response. Yes, the bundled AC power adapter and micro-USB cable is used for charging. The AC power adapter output is 5.2V and 1.35A. Also tried to charge the phone for a few hours but still, the same problem is encountered.

Does the LED indicator light up when charging? Have you tried charging while being connected to a PC? (this will take longer to charge)

Sorry for the late reply, sir. Many thanks for the prompt responses. As advised by my brother, he tried charging it again using the AC charger for more than two hours and turned the phone on. Good news that the phone booted properly.
It seems that the problem is really about a drained battery. This issue can now be closed.
Thank you very much.

Hi Sir, I have tried it. But it is still not going into recovery mode. And when to connecting to charger the dead android symbol is getting popped up and the mobile is heating heated without switching on.
:crying:

Hi Sir, yur reply is very much necessary as i am stuck with the dead symbol even after battery getting drained and recharged as well.

Hi Sir santhosh_kv,
My brother's phone couldn't be switched on before and we just sent the phone to the service center. After a month or two, they replaced the unit with a new one. I think my brother got a lemon unit before.
Thank you.

Maybe there's something wrong with the system. Try flash stock rom using adb sideload. While in that dead android symbol, press power+vol up to go to recovery.

Hi Sir, I have tried the procedure u said. But nothing seems to be working. Please help me with this. I have installed the ABD divers and updated it. But its not working after re-switching on.

After using the phone until the battery was completely drained, I tried to charge it. Initially the indicator showed orange (suggesting it was charging), but after attempting to turn the phone on, it vibrated once or twice and the indicator stopped glowing. The phone has since failed to turn on at all, and connecting the charger no longer shows any sign of charging (ie. no orange indicator or on-screen battery icon).
Has anyone eno****ered this issue, or know of a way to fix it? Let me know if I can provide any more information, and thanks

Help to fix charging and usb connection issue

Hello dear.
I have a problem with my p601,
I cant connected my tablet to PC.
When i connected, just charging and no any connection.. In odin or storage not show a device, adb not connected...
And when i used a charger show an red stroke on battery icon. And charging is very slowly, during night only 50%.
I'm root my device, install twrp, and install cyanogenmod, but nothing change.
Now whats your idea? How i can fix this issue?

This may be an obvious question but have you tried a different cable or charger? I always found running on stock ROM that charging was an issue unless I powered it down. I have used a 12W Crapple charger and that seems to work ok but charging has never been an endearing part of the this tab.
So in Odin you it doesn't work? Could you have some dirt or contaminants in the USB port, start with the obvious, change the cable, use a different usb on the pc or try another pc altogether.

I had same problem, i noticed that the usb port was loosen little bit, i had to open the tablet apply small pressure with plier to afjust the usb port,,,, and now it's perfect.
