I can confirm that the Lecco USB-A to USB-C cords are of good quality free from soldering defects etc.
My non-charging symptoms are that the phone starts to charge and then stops charging, The USB cord works fine for file transfer
End to end connectivity of the cable is fine, The USB-A end connectivity to the charger on the (+Ve, Gnd, D+ D-) is intact.
There is a inline Fuse which was intact
A IR1 designated diode or resistor ? in the USB-C end .. It was open circuit ? I will work up a diagram when my eyes recover
I cannot confirm the contacts that the USB-C makes with the phone BUT the fingers all look fine. !
Mine is marked with the "Le" logo on one side, so it's easy to remember the side which you mention about. I had no problems with the cable and I never cared about the side of USB-A that I plug in.
Still, a good point though.

Yes mine has the logo as well, I concluded this possible cause for failure because its so easy to plug in reversed ? I will open the connector in the next few days to hopefully show where the failure occurs .
I've just compared the USB-A male from the OEM cable with another regular male port and I see that LeEco did a good job with it. The middle part is very thin and positioned very well. By plugging it into a female port and even reversing it, I haven't noticed any flexing of the middle part either way (I've watched it through the 2 small holes that keep the male port attached). There should be some movement, but I think it's too small to be noticed.
Anyhow, I'm looking forward to your disassembly of the connector.

Scratch that theory ! Indeed the Lecco USB-A end is robust and NOT the problem ?! All wires to Pins test out ok.
I will need to investigate the USB-C end or the cable !
cheers
Thanks for the teardown.
I do agree that too many people were complaining about the cable that somehow it stopped charging, so there should be a weak point. Most of them reported failure within the first week or so, this makes me believe that it should be some bad soldering somewhere. It just needs few flexes and it's broken. I do suspect the junctions at the plugs either side.
Some safety precautions:
- Never remove the charger out of the socket by pulling the cable
- Never remove the cable out of the USB port (either side) by pulling the cable, pull it from the plug
- Whenever you are carrying the charger in a bag, remove the cable from the USB port
- When not in use, spin the cable to form a small coil of about 10cm in diameter (very subjective, the point is not to form an angle that might damage it; a 90 degree angle when caught between the drawers, etc)
PS: Was you cable broken or something?

I can confirm that the soldering and the wire quality are top notch, End to end connectivity is good!
At the USB-C end there is a fuse inline with the +VE (Red wires) intact in my case, and a IR1 Zener diode (I think) , Or a resistor ?
Its open circuit ! (they normally go closed circuit ?) I have noticed sometimes plugging in the Power pack that the mains pins will give a little spark ?
So maybe that has blown the Diode ? IE Plugging in the powerpack with the cord attached might not be advisable ?
I have yet to work out the wiring .... of the IR1 diode / resistor ?
The only thing I cannot confirm is the contact made by the USB-C fingers onto the Phone connector..... I won't be doing any more.
Replacement cords are cheap
My cable is fine but I have a problem with my charger. It charges fine once, but having been disconnected (even midway through charging) it won't work again for at least a day. After about a day it generally works again, but again only one time. Very strange and annoying.
In Germany we have a couple of guys complaining about the Leeco OEM cable too. But if I remember correct these guys had a different kind of cable in their package.
USB-C to USB-C instead of the USB-A to USB-C variant.
That seems to be the case for people who had buying the phone from banggood with shipping from Europe direct.
Maybe there's another manufacturer of the cable with a bad soldering standard!?
My girlfriend and myself were both receiving​ our Max 2 with the USB-A to USB-C variant of the cable about nearly 5 Month ago and no issues so far!
USB-C to USB-C should be the way of the future for everything !
My cord had been working fine for 6 months, never unplugged from the charger, never rolled, never damaged.
It just went faulty after I had transferred files from my PC to the phone for a rom upgrade etc that the problem occurred.
Just coincidental ! ?

Trying to find out if there is such a thing as going from extmicro usb that the evo and flyer have to a usb type A (or any other normal usb).
Need a right angle to plug into tablet for car install and found that I can fit a microb angled cable into the tablet, but now need to take the car charges extusb and get an adapter to hook it all together.
You can just buy a regular micro USB extended cable. It fits in the flyer/view charge port.
Proprietary cable is the one on the right. Regular micro USB on left.
I am installing the tablet in dash of a car.
I have the oem car charger because its only one with right voltage. But I need a angled usb for clearance issues. So im trying to figure a way to go from the charger EXTMICRO usb to the angled usb.
Searched around and have come up completely empty.
I'm working on the same project and found this thread searching (again) for more info on extusb. The solution I came up with for getting enough clearance to use the port requires disassembly and if you plan on keeping the warranty, it's probably not a good option for you.
Anyway, my solution was to make some small right-angle brackets for the pcb that contains the extusb port. It requires material for the angle brackets and two small screws with nuts. See attached for a better idea.
I actually got the tablet installed and fairly well, but have since removed it to come up with better designs for charging, access to the power button (and possibly volume buttons) for recovery actions, turning the screen on/off with ignition, and potentially microphone relocation.
You may want to check out http://www.dealextreme.com/ for right-angle and other adapters if you don't want to open up the tablet.
PS: Protect that screen. The plastic is very soft and will easily scratch.
I don't follow.
I thought the HTC car charger was a plug with a USB port in it just like all the others. I thought this might help, but I probably have no idea what you're really looking for
http://www.amazon.com/Cables-Go-Right-Angled-Micro/dp/B005EV2LAM
If you *need* to use the 12pin micro usb that the view has (which from my understanding was only there for the docking station utility), then you might be out of luck unless you can build something yourself.
Im looking for a cable like you linked to, but then I need a way to connect the flyers car charger special usb tip into it. Only way I can think of is to carefully grind the corners so that it will fit into a micro B female connection.
But the chargers are not cheap and if I F*** it up Im out $30
On a kia soul forum where others are planning on doing the same install with the flyer, one guy has come accross a company that makes custom cables. He said that if We send the car charger to them they will replace the usb tip with a micro B 90 degree angle for $25.
So A person is sending the charger to them to have it done and is going to let us know how it comes out.
jacobbones, can you provide a link to the kia soul flyer thread?
Yes, here it is.

Talk about the custom job is near the end of the posts
opening up the car charger and replacing the cable is incredibly simple. I have done it so many times, I can probably do it blindfolded. I actually had to go and replace the OEM chargers cable with the USB cable that it came with because my damn dog chewed threw the charger cable. Didn't come back very pretty, but it works, that charger has got the be the best charger built I have ever seen, incredibly difficult to open, but I'm sure the car charger is a lot easier to open, you just need a soldering gun and it should be easy.
Sent from my ADR6425LVW using xda premium
First off I'd to say hello from Alaska,
Ok this may sound strange but does anybody out there know where i might find or have one made, I'm looking for a cable with 2 40 pin connectors on both ends, 1 male and the other female. This is for my TF201 and dock, I would use it so I don't have to take off the case to the Prime just plug in to the prime and to the dock..
Thank you all Stan
Cables to Go should be able to do this for you. I've had them make custom cables for me before. It likely won't be cheap, but they should be able to do it.
www.cablestogo.com
Just in case anyone was curious, I thought I would try to get lucky and see if a female-female USB adapter with a standard ASUS 40-pin cable on either end would work. However, it was only a novel attempt and the tablet does not recognize the dock as I had hoped.
I am sure Cables-to-Go could get something to work, but I agree that it will be quite expensive. It would be nice if there was a jumper cable accessory to accomplish this same concept since I am in the same position as the OP and typically carry the tablet in its own case and only use the dock when I have alot of typing to do.
On a side note, I did confirm that my Logitech Anywhere Mouse with the Unifying Receiver does work 100% with my tablet and Dock!....I just may be able to leave the laptop at the office yet!
Does anyone have a mapping of the pins and wires? I would like to try and "splice" two cables together to try and make a jumper cable but would need to make sure that I make the right connections. Any assistance would be greatly appreciated.
I don't think that's going to work for several reasons.
First and foremost, if use two TP USB cables as the souce of the parts, you'll end up with a "jumper" cable with male connectors at both ends. You need male to female, remember?
Secondarily (and almost as important) is the number of contacts on the USB end of the cable. USB has four conductors plus shield and nine conductors plus shield in USB 3. Taking a cursory glance at USB plug on my TP cable, that's all there is. I don't see any additional conductors.
Following this, it's EXCEEDINGLY unlikely that the cable has 40 wires (one for each pin on the Prime end) running the full length. If it did, where would they connect to on the USB plug? Kinda silly to include extra copper to go nowhere.
Instead, if you were to pry open the 40 pin male plug, you'll see that most the pins aren't connected to anything. They're not needed for the USB cable.
Sorry to say, this just isn't going to work.
If you do choose to clip one of your cables just to have a look-see, cut the cable somewhere in the middle. If you cut right up next to the USB plug, you won't have ample wire there to repair what you're about to break.
I am aware that you will need a female adapter to make a true "jumper" cable. However, there may be a way of jerry-rigging a connection to the dock if a female connector can't be found (I have yet to find a part online).
My question is more in regards to whether or not anyone had a schematic of which of the pins are connected to which of the respective USB pins so that I could determine the best way of making a connection....short of having a cable for the ASUS TF201 like this: iPhone Extension Cable
I was thinking about getting a magnetic cable because I want to spare usb seal from wearing out. I noticed that some of the people are having problems with it and they managed to brick their phones by plugging the cable in wrong direction. I checked few of cables available in stores and I noticed that they are not marked in any way and there's no information about "how to plug it in". I'm wondering if there's some kind of rule how to plug them in. Is anyone using them instead of Sony dock?

I'm using it for some months now, and I can say that if you're using the original Sony cable, you're pretty safe.
If you look at your mobile carefully you'll see that the magnetic frame for the connector has two pins with different geometric forms. Those pins fit exactly on the holes on the cable, in only one direction. You'd have apply a big force to make a mistake.
Besides this, the cable "head" is not symmetrical: one side has a wire, another doesn't. So if you plug the connector with the wire aligned with the "foot" of your mobile three or four times, I think you'll find it too strange to plug it with the wire aligned to the "top" of your mobile.
The experience with the Sony cable is great, and I don't have enough good words to recommend it.
I haven't noticed that connector pins are not symmetrical, thanks for pointing that out. This will definitely help. I'm wondering how people managed to brick their phones by plugging it in wrong direction, if you need to apply some of the force to plug it that way.
I'm thinking about cable because dock costs a lot, considering that I'd use it only for charging anyway. What's the code for magnetic cable from Sony? I might try go grab these here.
I plugged it upside down once. It rebooted the phone. That was it. Nothing bad happened.
The QC4.0 announcement is pretty new and I'm still pretty foggy on these details;
1. What maximum wattage will the F1 accept via USB-C PD? I'd like to get a charger for use on-the-go.
2. Does the USB-C port comply with the USB 2.0, 3.0 or 3.1 standards?
3. Does everyone's cable wiggle around a bit in the port?
4. Sometimes I hear a barely-audible crackling sound when connecting the cable; doubt its shorting but what could it be? The cable pins as they come in contact with the phone contacts?
5. Does anyone else's port look a little weird? I can't attach an image but it looks like the edge of the plastic connector inside is a little deformed.
I tried to hook up a game controller via the OTG adapter and it appears to not send any power out from it. Even with a USB thumb drive and other USB C adapters, nothing seems to work. Has anyone else noticed this? You can transfer data via the cable just fine, but I find it strange it doesn't send any power through the plug.
Have you tried connecting it the other way round?

I noticed the same thing. I believe it's because once it comes out the other side with the 5-pin adapter, it is then reduced to the old micro-usb specification, which uses 5 wires. True USB-C connection has like 20 or 24 pins. I was able to get a couple very basic OTG of things to work, like a mouse and a thumb drive. BUT HERE IS THE CATCH - The mag connector has 5 pins, reduced from 20-some on the C connection.. so true USB-C connection is no longer possible once you get on the other side of the connector. So the trick is to NOT use a USB-C OTG when it's in the case with magnetic adapter. You must use a Micro USB OTG with a Micro-to-C adapter attached to that. Even so, not everything worked just by sticking on the Micro-to-C adapter.. Mouse and a thumb drive worked, but my ethernet adapter and VGA/HML/HDMI adapters did not. Out of the case, I can use my USB-C to HDMI cable to display on my TV. But same cord does not work with the magnetic adapter with the case. It is simply not possible because the reduction of contact pins from phone to case to magnet.. One more thing to consider, if you're trying to do anything other than charging, make sure the magnet is on the right way.. there's a little logo it should be in the front.
If I can come across a spare or broken Dual Screen case, I'd be curious to take it apart and see if it would be possible to rig it up with a better plug for the case.. find which wires go to the workings of the DS and leave them intact, but then try to replace the magnetic pins with a female C plug that has all the contacts intact still..

Thank you @Seymour_Asses ! I saw here https://twitter.com/konic0s/status/1202966945693220865 that LG G8X supports USB-C to HDMI adapters but I didn't know if it also worked with the Dual Screen case but now I know it doesn't, thanks for the information, very helpful ! :good:
BTW I think that when you connect the Dual Screen case to the G8X it uses the dedicated USB-C high speed pins of the G8X for video-out so these pins are not available anymore for other HDMI out, I'm not sure about it and don't have any proofs but it seems you are right about not enough pins on the mag connector.
If i remember correctly, the manual states that most USB-C functions wont work though the dual screen case. I think there was some speculation that its due to most of that bandwidth being used for the second screen.
Quite simple: the Mag USB-C adapter is for charging only. It drives me mad as i have a professional USB-C headphone that I use for conferencing.
But I understand the reason: when in dual screen, the USB-C data connection is in use dor the second screen, enabling the USB-C connection beyond that requires a hub to be built in the case "before" the DS connection (so it wont work building it in the dongle itself).
I wish LG went with a Pogo connector on the bottom or on the side to activate the DS case. This would have made the chin slimmer and freed up the USB-C port.
Anyway, it is what it is now, and i will not trade my LG G8x DS for anything at the moment... Until maybe that Surface Duo phone for which I might need to sell a vital organ ?
