All Sorts of USB-Related Weirdness - LeEco Le Pro3 Questions & Answers

Have had a stock Le Pro 3 since Dec 2016. No real issues prior to the last few days.
1. The device will only charge when powered ON. If powered OFF, the phone will vibrate once, the LED indicator will briefly come on, then turn off. Unplugging it and plugging it back it again does literally nothing--no vibration or LED indicator.
2. The device will not power on while plugged in. It will simply vibrate after a few seconds, then nothing.
3. The device will not connect to my PC for data. Have tried four different cables without success. It will charge from PC, however.
4. When connecting to USB and powered ON, the phone will vibrate and show the battery charging indicator, but will then hesitate slightly (battery charging indicator turns off), then shows the battery charging indicator again. Not sure if that means anything, just seems odd given everything else.
5. USB headphones do not detect/work.
6. The USB to 3.5mm adapter for headphones does work.
I've tried a factory reset to no success and have ordered a replacement USB C board just to be safe (it was $5 shipped), but am at a loss as to what to do. Tempted to let the battery drain completely and see if that puts everything into working order, but as it's my only phone, that seems a bit risky if I can't be sure it will ever start charging again while powered down.
Anyone here run into these sorts of issues before and any advice if you have?

A $5 board will not solve your problems. It will likely get you into deeper trouble because it doesn't support mtp and otg. It's only good for charging.

Your connector is probably damaged. You can try contact cleaner/lubricant on the connector. It may fix your issue. Something like this https://www.electrolube.com/products/contact-lubricants/eml/contact_cleaner_lubricants/
I use lubricant often on usb-c connectors even if they are working. Just extends the lifetime of connectors, the pins are really small after all so the contact surface is not much.
Replacing the usb-c board is not an easy task. You would need to remove the screen etc.

Universal Charging

Hi All
When I have my universal plugged into my USB on my Laptop it dosnt chanrge the device until I switch the screen off is this normal ?
Is there a setting ?
Thanks
Steve
I have the same with USB cables and several chargers (wall and car) I think it depends on the wiring.
Mostly the MDA start charging after a few seconds even if the screen is on though.
Suspect your laptop can't supply enough power through the USB port to power the screen & charge the battery.
You might want to try reducing the screen brightness to minimum to see if that leaves enough spare power to charge the battery.
Mike
It's normal. The laptops suply 0.5A but your charger suply 1A. So you sould keep screen off, or BT and Wifi off if you want your pda increases the battery level instead of decreasing......
Well as I experience the problem it is not a problem of too much load. If I switch the screen back on after it starts charging it works fine still.
sure. Because the screen on eats much power
and it doesn't when you switch it on later?
Let's se. If you turn off the screen using some program (not the pda, only the screen) the energy consumption will be less so your pda will charge. BUT if you let the screen ON the pda will spend more energy than the received by the laptop so the battery level will decrease......
I doubt that is what he is referring too. I assume he's talking about the orange led. That does sometimes not come on when the screen is on, but if you swith it off it comes on and then you can switch the screen back on and charging works fine.
I really doubt that the MDA uses more power than USB can supply. You'd have to have a lot of other devices connected to the same port/hub and seeing how this is on a notebook ...
Probably does not check power requirements all the time so you may get into a position where it can charge & have the back light on.
So one of two things will happen depending on how well you laptop was designed.
1) It will take a very long time to charge while the display is on.
2) Damage the USB power supply as the PDA will take more than the USB port can supply without damaging it.

Of course I'm not the thread starter, but what I have experienced is that it's not about the speed of charging just that the led needs to go orange and that it will not do so when the screen is on (or with a delay)
So in the end the real problem is that charging does not start when the orange led is not on (as the device remains switched on). Not that it takes longer when the screen is on. Simply that there will be no charging at all.
I have ended up with an empty battery because of this myself a few times. If I remember to switch off the device when it's hooked up then it charges fine if I switch it back on.
I have also had the same problem from a 1A wall charger. So it's not just a matter of power being available. It has to be something with wiring or signals from the charge cable too.
I'll try to see what the difference is between chargers that do work immediately and ones that only work after you switch off the device.
Some USB ports may also be designed to supply power (or a bit more umph!) to external devices. For example, one of my laptops has two USB ports; a normal one and one with a "plus" symbol designed for powering devices like floppy, or USB hard disc drives.

Completely agreed. I have exactly te same situation, whether I use the computer's USB power or a 1A wall charger. I have tried various cables with to no avail. If I want the device to charge, I must:
1. Turn off the Universal by pushing the power button,
2. Then feed the electricity,
3. Then the orange light comes on, and it is charging,
4. Then I can do whatever I want with the device as it charges.
When my Universal was new, it did not have this issue, so I do not know if a firmware update, a reset, or some third-party software caused this to happen.
My understanding is that the display backlight uses most of the power I can get a decent charge by just closing the lid rather than using the off button.

My battery was down to about 38%, charging via USB (Lid closed) charged upto about 83% after about 3hours - Not quick but good in an emergency.

Got a bit of a weird update here...
Normally, my unit does the same as above...wont charge if display is on, removing cable, closing lid/turning off then applying charge resolves issue.
Now, I used to try the charge cable first, if it didnt work, unplug, close lid, apply charge again.
Past few days, I have been inserting the charge cable in and pressing power (lid still up)...at this point it doesnt charge (does if you close lid instead of pressing power), but if i now close lid and re-open lid, the screen comes on and so does the charge..at the same time ?!?!?! :shock: :shock:
I have tried this process and left lid closed for few mins before opening it, but the charge starts when the lid is opened not closed.
And also, if you get unit charging, then remove charge, you can apply charge again in any power state (within 3 mins) and unit will charge instantly?!?!? After 3 mins you have to mess about with power and lid...
So, is the charge linked to the lid closing, or linked to a change of status of the units power??? :roll:
EDIT: ahh haaaa...the 3 min thing was cos my power down timeout was 3 mins :wink: so I did some testing;
1. lid up, screen on, backlight on - insert cable (no charge), press power (no charge), close lid (no charge), open lid (charge)
2. lid up, screen on, backlight off - insert cable (no charge), press power (no charge), close lid (charge)
3. lid up, screen off (from timeout, not power button) - insert cable (no charge), close lid (charge)
4. lid up, screen off (from power button) - insert cable (no charge), press power (no charge), close lid (charge)
......helpppppppppppppppppppppppp :shock:
Ha, ha, I guess these machines are becoming so complex that they start to become really "alive"

how many secs elapse before you close lid in these experiments? it is normal to wait a couple of seconds before the charge led comes on.. sorry if this was too obvious!
other ideas: the contact is not good, and when you move the unit it could get better.
do you use the usb sync cable to charge or wall charger? i use the latter. supposed to be much better.

I have tried these test with USB from laptop, USB from PC, USB from powered HUB, Wall charger and Car Charger...all same results. And I did wait for several seconds before closing the lid, in the vain hope that it would start charging...sighhhhhhhhh.
Only difference I have noted...and this may point to a possible app to fix it...if you use USB cable from PC/Laptop with ActivSync installed, it starts charging more reliably ?!?!? Kinda points to this being a polling problem within the units software ie: activsync connection sends a request which prompts device to check port status, sees power and starts charging...whereas a connection with only power doesnt force a poll. Problem here is, laptop/PC direct connect (as opposed to a hub connection which can cause some problems) is only 500mA power...wall charger is 1A...so charging time on a USB connection is VERY slow.
Anyone know of an application (or can write one) to change polling frequency on device??? Or maybe there is a registry setting that covers this?
*prays on knees* :lol:
You have the problem with the standard MDA Pro charger too? Or do you have another wall charger?
Between the different chargers that I have I see great variation in the time they take to start charging. Some start immediately, some will take a few seconds and some will never start if the device is on (or screen is open) Each charger behaves quite similar every time though.
In my case I doubt software would help much. I actually have 2 MDA pros ( (it fell and the screen broke so I got a new one) They each have a different rom and I think the behavior between them is similar. Although I don't recall ever having the MDA pro mot charge in my car as it did with my old machine.
I'm still guessing there is a difference in a signal line somewhere that the MDA pro detects the charge quicker.

Atom life only recharges when turned off

Hello,
my problem is strange.
When I turn off my Atom Life it can be charged (USB, External Power Supply).
Red indicator light on.
When turned on (in use) it does not charge. The charging symbol in the status line shows the unit is connected to external power, but the red indicator light is off, and power continuously goes down.
I already tried a hard reset, but that did not help.
Does anybody have an idea?
Sorry, I forgot to mention that everything with charging went fine earlier (until some weeks ago)
charging
same thing with my XDA ATom dude
I have ordered a new battery for mine at ebay (did not arrive yet).
Maybe it helps.
Otherwise ...
Ok, the battery came in and it does not change anything.
Still the same issue.
So I am gonna litter it...
bye bye
New info,
there seems to be a bad contact at the USB connector.
If I connect the USB cable and hold the plug in a specific angle, then the charging light (red led) turns on).
Brought the device to a friend of mine. He's good at electronics and tries to figure out and fix the usb connector.
wait and see

any news for your problem ??
i'm having this problem too
i brought used one and seems the battery is almost dead and can't charge when device is ON
Thanks!
I got a used atom life and bought a new main battery for it. Charging via USB cable connected to my notebook is working fine. Using the (wall socket plugin) power supply with the same cable it behaves the same way you described it. It starts charging only when the device is turned On and back Off. In my opinion the power supply is the reason. Maybe it is to week ar has some sort of security switch build in, which is protecting it against to high power consumption.
In my case it was definitely not the charger. I tried several ones and they behaved all the same (the original one wrked for long time).
It is the device itself.
I had it sent to a friend who was able to open it and a have a look at it.
The USB plug itself was a bit loose. But soldering it again did not fix the problem.
There seems to be a micro break of a wire on the mainboard (which is multi layered). So no real chance to repair.
I replaced my device by a HTC Desire which was available in Germany very very cheaply (you don't want to know the price because it wuld be too frustrating).
So goodbye Atom Life.

Now my phone won't charge

Totally stock (but i don't think it matters).
Plug the phone in, orange LED comes on.
Hold it or place in on the counter five seconds later, LED is off.
Had the phone since 6/4.
Anyone else having issues?
Are you using the AC charger ? I have two Evos and one of the chargers does what you are describing. The orange LED comes on and then goes off after a while and the phone stops charging. Does it on both phones, the other charger works fine with both usb cables.
Are you using the USB charger with a computer or laptop or plugging straight into the wall with an AC charger?
This does make a difference because if you are charging with a USB + laptop combination you could be suffering from the computer going to sleep and disabling the USB ports power to conserve laptop battery life. If you are having the issue when plugging into the wall, try plugging into a computer and selecting the "Charge Only" option when your USB debug comes up. Once it does this, allow it to charge for a period of time and then turn the phone off, switch to AC power plug and see what happens.
Perhaps you had some kind of over voltage spike on the charger through the AC plug. I could see it possibly tripping something in the phone to stop taking charge to protect the handset.
Also make sure if you do use a laptop, use a USB 2.0 or better port. More power and faster connection. Gotta love it.
Your charger may not be sourcing enough current anymore (for whatever reason). I have seen the exact same behavior with USB car chargers that were only sourcing 100-150mA.
Have you tried plugging the USB cable into a modern desktop PC? (Some laptops have reduced current ports, so a desktop is a safer bet)
Its definitely a current issue. I tried to charge my phone using my bluetooth headset's wall charger, but I got the behavior you are describing. The bluetooth headset's charger just doesnt put out enough current.
Are you using the charger that came with the phone? if so, you may want to exchange the charger...
im having the same problem when i connect it to my desktop, it sees it for about 2 secs n then disappears. My computer at work has no problem seeing the phone. i wonder if i need a driver or something for my usb ports, anyone have any ideas??

Probably not a driver issue, but that that rail from the power supply is either undervolted (say 4.6V instead of 5V), or can't provide enough current (amperage) or both. If I recall correctly, the Evo needs 5V @ 1A (+/- 3% tolerance).
Phone not charging
my phone has been charging fine since I got it... even been using the night desk clock app while sleeping at night for the alarm with it plugged in... everything was good...
With my phone about to die today, I plug it in to the wall charger, the led/batter indicator shows that it is charging... then POW.. it says I have a low battery and it needs to be plugged in... WTH??? it is plugged in!
The only thing I did today was flash the new boot.img for the cap fix over in Toast's thread...
Weird thing now is that I took my hero battery and put it in my EVO, plugged it into wall charger, and it stays charging... So, I put my EVO battery in my hero, plugged it in, and whola... it's now charging...
Please help as I am baffled.

that's your problem right there. that custom kernel is known to have charging issues.
I'm having the same issue with my car charger consistently. Plus my AC charger less consistently. For example, I'll go to bed and plug it in, the next morning I wake up and see the phone is at 80% charge and isn't charging. At some point over night, it gave up. This is with the stock charger too.

X10i not turning on / charging

Hi guys,
Suddenly facing a strange problem since last night.
My x10i was running out of charge & i connected to the comp to charge while i was working. I noticed the charging speed was extremely low, so i restarted the phone to see if it would help. Did not.
Thought there is some problem with the cable, used a different cable as well, but no use.
The slow charging had stopped and eventually the phone died.
Tried connecting to the socket & charging, still no use.
The red led blinks when i connect the phone to a charger via the usb or the socket.
needless to say the phone does not even boot up now, obviously for no charge...
any ideas wat maybe wrong or wat i could do ?
please advice
Have you tried to let it charge for some time in off mode? As long as your battery is not dead, and the phone get the right voltage through the USB connector it should charge in an "emergency mode". This is a slow way of charging, but allows for charging without any electronic circuits to monitor it, it is not the same as the charging screen that usually displays when you connect the phone while it is powered off. Usually when a phone is completely discharged it needs to be connected at least 15 min, sometimes a lot longer, before the electronics kicks in, and starts the speedcharging.
My best advise would be to connect it to the mains charger, or a USB port you KNOW supplies power. Some laptops cut down on the powersupply to the USB ports when they run on battery. Let it be connected for a long time (several hours), and then try to power it on again.
If that does not help three things can be wrong
1. Somewhere the USB connection is broken, either in the cable or in the connector on your phone (or on the PC's connector, but that is less likely).
2. The battery is dead, modern batteries contain circuits that actually disables the battery when any given parameters gets outside the defined limits. This is to prevent the battery catching fire. On some batteries this renders the battery useless, and you need a new battery.
3.) The mainboard of your phone is dead, and hence nothing works, can be ruled out if you can borrow a battery from someone to test if your phone works then.
I hope a good and long charge can sort out your problem, that is the easiest fix, and it is free.
Hi O_K,
well, i have been charging (or trying to) the phone since it died last night.
i have used different chargers & different modes of charge (through the system & the wall socket) - no joy at all.
the LED blinks red a couple of times when connected.
Very occasionally, the SONY ERICSSON logo (startup) shows on the screen & it switches off again, back to the blinking.
So charging for a long time & through different chargers has not helped.
gonna try a different battery now to see if that can help.
Thanks for your response!
well, tried switching chargers & batteries.
The problem seems to be with the charging unit on the phone (USB)
with any charger or battery, wen connected the led blinks (like wen the phone is charging), but there is no charge happening.
eventually the phone dies, even if charging
any ideas?
There is a thread some where in this forum for fixing the same problem you have...I don't remember the exact name of the thread..if I find it I'll post the link here..Anyways what the guy did was
-Pull the battery out and connect the charger till the led turns green.
-put in the battery now and charge the phone...
and I think that was it.
Hope it helped..
EDIT: Found the link.

USB Charging issues / Computer does not recognize while on

So this issue happened out of no where after my phone died to zero last night. I tried charging it back up but all I could get out of it was the grey charging battery but it would only stay on for 1-2 seconds shut down and reboot. Let it charging for an hour and got to about 1-2% and it would die as soon as it booted up. Factory restored to OA6 and still see the same issue. This is also the odd thing... I was able to connect it to my computer and use Oden to do the restore! After lots of troubleshooting, trying 4 chargers, I realized wireless charging still works fine. Charged it up 100% over night and wireless charging is still working fine and phone is working fine. Still cannot get USB to be recognized while on either by computer or from USB charger. With a full battery, phone off, and USB plugged in phone still flashes the grey battery icon and reboots constantly.
Only thing I can think of is I had it in my pocket after spin class for a little and moisture might have gotten in the port?
Any ideas what happened here?
Update: I ended up just buying the Nexus 6P since I'm about due for a new phone anyways.
Well just figured I would pass this along. Was bored before and looked at diagrams to fix the USB board and saw this little port in the back you can access really easy. Decided to open that up and press the connection down a little tighter (the USB board is separate from the main board). USB didn't work before doing this, then pressed it tighter plugged USB in again and it worked.
