What cable you're using for mtp. The original one from the dash charger? Did you tried another cable?

Then there's maybe a damage of the data pins of the USB c port of the oneplus 5. The data pins are for data and dash Charge.

As I said... You should check the pins or go to service center.

Hello, Have you solved your problem?

Take toothpick and try to scrap all the dirt inside USBC port and on pins. I had similar issue, light touch to usb cable would break the connection and dash charge sometimes won't work. Now after cleaning everything is working fine.
But be very careful to not break USBC!!

Dash charger issue
Since today, my phone keeps cycling charging and not charging constantly on dash charge mode. If I use the dash cable with another charger, the phone charges constantly (but not dash obviously). If I use the dash charger with a non dash cable, the phone also charges constantly (but not dash). If I use the dash charger and cable with another phone (Huawei for example), it charges that phone without problem.
Please help.

I would recommend cleaning the pins inside the ubc-c portion of the dash cable that are not fully inside the hub, I believe these are the proprietary charging points for dash charge and get dirty and very finicky

Try cleaning the pins on the cable as described above and if that doesn't work, I think it's time for you to buy a new Dash cable.

Were you able to get it fixed? I am facing the same issue and wondering what to do. Funny thing that I have the same issue with my OnePlus 3T, and changing USB port on that one did not help.

My bad, sorry for not updating.
I have resolved this issue. It turns out the cable was dying, so I bought a new cable. Same wall charger.

Dash charging and USB features not working. Help!
My OnePlus 5 charges slowly with a Dash charger and USB features don't work. Does not show up in ADB, Fastboot, or normal mode. Any suggestions how to fix this?

It's probably either the cord or the charging port. I had to replace the charging port on my first op5 which had the same symptoms as you. It gets a lot of dirt in it from working in the bush.
Try a different cord and clean the port out and if that doesn't help you may need to replace the port.

I've confirmed that Dash charge does not work even with another charger and cable. I would go ahead and do the port replacement but I'm a bit sceptical that it would work. That's cause I did try to change the port on OnePlus 3T which had the same problem and it did not get fixed.

In my case a replacement charging port I bought from E-Trade supply fixed the problem. They usually have good quality parts but I found out when you get a defective one, they will only refund the part price and not the shipping which was 3x the cost in my case.

[Q] OEM usb cable malfunction

Hello community,
trying for half an hour to connect my note 3 to the pc using the OEM usb cable, I kept getting error 43 "Unknown Device" stuff but the phone was being charged. After that, I plugged it in my usb 3.0 external drive cable and got recognised instantly. What do you think is the problem here? I did happen to land the phone-edge of it in a yogurt bowl last week but, after cleaning it, it has been working normally this much time!
(Hope) someone else had a similar experience and worked it out...
Thanks,
jim
Original cable that came with my Note 3 has broken wire inside from new, I need to move it around few times just to get it connect inside and charge phone, Note 3 itself works fine with usb2 cables, or usb3 cable from my back up HDD, so I strongly suspect one of the wires inside your cable broke or has poor connection as well, but here it's data line, not power like in mine. Solution is very simple, use another usb3 cable, that should give you fast charge, or even usb 2, but here probably charge will be slower. You can find inexpensive cables online, also I don't think cables have full 1 yr warranty, like phones do but you may as well try warranty claim. BTW there is nothing special about Samsung charging cable as far as I know and at least in my case any USB3 cable will charge my phone at full speed, just like original cable as long as charger is original.

yes, Kies 3 has been installed since the beginning with the drivers. And as long as the phone is recognised through another cable, the drivers are definitly installed! Thanks again!

As long as I have the backup cable, I just leave the OEM in the wall charger and everything is fine. There is the fact that my Knox is 0x1, but I can just try the warranty with the cable and the receipt :angel:

First thing Try another battery.
Flash clean stock official firmware via odin.
Use orignal charger and usb cable came with the phone.
Go to settings/battery and enable fast charging.

First, do you know that there are 2 types of USB ports?
There are 5 pins USB and 11 pins USB.
Our Note 4 is using 11 pins version
Did you replace the USB port with the correct one?
Second, the cable also have 2 version, 5 & 11 pins.
11 pins USB is necessary for the Fast Charging to work properly

no sadly i dont know the difference between 5/11 pin usb,
but i used original chargers from a retail store when i was trying different solutions.
also i did order a original veizon usb port from ebay(ive got sm-n910v). looked like the original , and i ordered 2 from separate vendors.
one of the products i ordered looked of lesser quality. I tryed both

Nexus 6P no longer recognizes any USB-C to USB-C cables.

Hi, I have a very strange problem. My 6P no longer charges or syncs with any USB-C to USB-C cables. I've tried 4 different cables. Two chargers and my computers USB-C port and none of them work. It is extremely frustrating. What does work is USB-A to USB-C though. I just hate not having quick charge anymore. I've tried wiping dalvik and cache, which has worked before when my nexus would stop charging. But, now it no longer does anything. I've tried booting into safe mode to see if it was any apps that might have been causing it. But, that doesnt work either.
I am on Marshmallow, rooted, unlocked bootloader, running elementalX kernel, and xposed as well. I've been running this set-up since I've gotten the phone. Any help would be greatly appreciated.
First thing (Me) someone is going to tell you is to flash to stock and test.
Can you check if the USB C to USB C charging or data sync works while in twrp?

Nope, not functioning in TWRP either.
You might want to try reflashing your kernel. If that doesn't help reflashing stock and starting clean seems like your best option.
What does this file shows (from a terminal) after or when connected to a quickcharge charger:
cat /sys/class/power_supply/battery/constant_charge_current_max
Maybe the problem is physical. Clean you port out the best you can without damaging it.
Just wanted to give a little update. I restored everything back to stock and it's still not charging using multiple different USB c to USB c cables. Tried cleaning out the port as well. Still scratching my head here

I think it is a hardware issue, Im having the same problem and I never used a custom ROM or rooted my device, factory reset didn't solve the problem, now Im using a 2.0 Amp USB A charger with the USB C to USB A short cable, it charges at a reasonable speed (even says Rapid charging on the lock screen lol)

Problem recognizing charging, headset, and PC connection

Hello boys! I have a very serious problem with my LE PRO 3. Since yesterday, the following is happening BUG: When I connect the charger, it does not load immediately. It only loads if I reboot the device. And if I take it out and put it back, it stops loading again. This also happens when I connect to the PC. The device only recognizes if I leave the cable connected and restart. With the headset the same thing. It only recognizes if I leave it connected and restart the device. I'm on the Cydrass Google edition ROM, and my device is the x720 version. I have already switched to other ROMs (LineageOs, Ressuection Remix, and even the Chinese STOCK ROM 26s, and the problem still persists!) Apparently it's a serious problem recognizing my USB port I do not know what else to do! Please, help me!
even first buy , do you have problem ?
To Vitor_147
Remember, if you change the stock original LeEco rom you cannot say "have a problem with my LePro3", it's no longer the original combo "LePro3" (hardware + software) so expect (and accept) anything (better or worse!) and report the defects to the rom developer.
Now some helping things!
Apart to clean the phone usb c port and to try a new usb cable, you can:
With the usb cable connected, switch the usb debug off (or on) (developer options) then check if your computer detect your phone.
Even if your computer doesn't detect the phone or your phone seems not charging battery, if the usb cable (and charger) is good in 99% of the cases it charges the battery even if not at full charge rate (expect a minimum 4 hours charge time).
Before to give up, the last try is to bring your phone back to factory conditions with everything (but everything!) under the exact conditions of how it came out of the factory, then you can start over there and have an idea of whether the phone has a hardware defect or if it's just a matter of software.
I hope you solve the problem, if you find the right solution please report it here, so other users can learn how to solve this problem! Cheers!

I already wrote this up in Omni thread, so I'll keep it short. I've also been experiencing this same issue for a while now, it first happened on stock rom, reboot solves it. Darko tried a fix in his eas kernel, seems to fix it (so maybe somehow kernel related). I believe it might be somehow related to the usb-c controller, cause I found cases online of similar issues with pixel phones (i believe the controller manufacturer is the same as in our phones). I actually know the exact moment when my problems first began, after I used my OTG adapter to connect a usb mouse. Few hours after that, the phone wouldnt charge.
{Disclaimer - this part is purely my theory}
I think it maybe somehow related to a safety "switch/fuse" of sorts, or something to do with static discharge or something similar, and here's why. I did a loot of trial and error since the first time it happened to me cause it scared the sh*t outta me, thinkin my phone is broken. I am vigilant about careful handling of usb ports and such, (ocd-ish really) so theres no way I physically damaged it, its not loose one bit, cleaned it out, tried wiggling the cable around anyway, has no effect, so I excluded the possibility of a faulty port/soldering. A few occurences to note
No1 - if I plug my phone in the charger first, and then plug the charger in the outlet, it breaks the port, I have to reboot to fix it. But plug the charger in the outlet first, then the cable to the phone - no problem. (Static discharge of sorts?)
No2 - since it started happening, the only way my usb-c OTG adapter works is if i first plug the adapter in the phone, and then the desired usb device in the adapter. If i try to plug the adapter in the phone w/say a usb stick already connected to it - no go, doesnt work.
Oh... I'm sorry for what happens to your phone! It's true the safest way to charge a phone avoiding current surge/spikes/shocks is to plug first the charger to AC outlet, then the usb c plug to the phone, then the usb plug to the charger. If possible, never plug/unplug the charger to/from the AC outlet if the phone is connected to the charger.
When the phone is full charged, first unplug the cable, not important which side first, then unplug the charger. If the phone is still charging, better unplug first the cable from the charger side to avoid micro spikes on the usb c port.
If you cannot obtain a normal behavior of the usb c port neither with reflashing the phone with the "qfil" system, perhaps a logic port of the usb c port is burned or simply in undetermined state, in the last case a total battery discharge may reset the logic port state and the phone can works fine once fully recharged. I'm sorry I can't help you better at this time! Cheers!

@orsonbear, thats my train of thought aswell, micro discharges occuring while plugging/unplugging causing the controller to freak out, or potentially damage the tiny connections (micro usb only had 4 wires vs 24! in usb-c). But I believe the problem lies somewhere on the software/firmware side, mainly because a reboot solves any issue I have. And also I just remembered, the first time it happened to me was a couple of days after I updated my firmware while updating to 19s, or 20s, cant recall precisely. Anywho, for me it's a minor nuissance, not like the OP who can only connect his phone once before rebooting (I can go for weeks before it occurs).

Yes,
I thought about letting the phone down completely, and see if that does not happen anymore!
Same problem here
Days ago it start happen, exactly how you say, i never change the stock software and it start happen randomly, I have to reboot to recognize anything that I plug into the USB c port, I try factory reset and change from 26s to 23s and it keeps happening so maybe I'm pretty ****ed, someone help me, in my country no one will fix the port u.u (sorry for my English).
Hellao! I'm having a very similar issue, charging works fine and the pc detects the phone but OTG and the audio on my headset is not working. Did someone of you find a solution to this problem?
1. x720, x722 or x727?
2. Where did you buy the phones? (Store names)
3. What kind of USB-C cable were you using? The one that came in the box? Have you used other USB-C cables and adapters to see if it works?
This could be hardware failure due to a lack of QCing from LeEco (just your average hardware issue) or a USB-C cable issue. It's ver. 1.0 on all LeEco Pro 3 models (right)? So I can't say it's the cable for sure. Has anyone attempted to take the phone apart to replace the port? do they even sell the port replacement?
Similar problem for me. About a month ago my headset stop working and the phone did not recognize it at all, tried with the adaptor to 3,5 mm jack and did not work either. Charging worked though.
Found a replacement chip with usb c port and ordered. Yesterday i replaced the charging port, but still the headset do not work at all, and connection to PC does not work ether. Charging still works as usual.
I ordered the phone from grossoshop 7 month ago with their rom. Tried this evening to upgrade the rom from 5.8.018 to 5.9.020, still grossoshop but no difference... It should not be a hardware problem as i replaced the type c port.
Should i try to flash another rom to see if there's any difference?
Any other suggestions?
Thankful for any ideas

Have you tried switching cables? Could you have broken a contact or something while swapping the port out? Have you tried putting the old port back in to see if the computer recognizes the phone with it? Unfortunately you're gonna have to try everything, even if opening it back up again is tough. LeEco phones aren't exactly known for their build quality. Are you x720? Well, flash whatever ROMs you can, I guess. Might as well try everything.

Yes, I have tried to switch the cables so no problem with them. Have not done a swap back again as the problem seem to be similar as before, so maybe a change to a different rom will be the next step for me. If change of rom does not work, maybe then I'll try to swap port again.
And yes, It's a X720
Thanks for fast reply.

Maybe it's not plugged in or attached correctly so the phone doesn't detect it. Sounds like a hardware issue to me, in all honesty. I once took apart my iPhone 5 to replace the non-functional home button and it wouldn't work no matter what I tried. I had to remove the battery, reseat it, and then attach the home button again. It finally worked after a reboot.
just report in on this thread, I as well recently purchased an x727 experienced the similar issue. Basically as described above no matter what roms i test is always have some sort of camera errors when charging.
sometimes charging doesn't work or camera doesn't work I have to reboot to get it to work. extremely annoying. I think it is hardware related.
Anybody else have a solution?

This my advice to anybody considering buying this phone don't why you will get zero support from letv.
I got luckey I have zero problems with phone .
I recommend spending more money and getting a supported phone by the maker.
If you do buy one buy it from Amazon where get a warranty on it.

And extremly slow charging from 9 to 100 % more then รณ hours.
Also the phone`s microphone is nog working at all!! And the headphone is nog working!

Replaced charging circuit well but now I don't have any USB data. Please help!

I have a h_3g NOTE3 phone (SM-N900). I just bought a replacement for the charging circuit because the slot was faulty after 4 years of usage, and it ended up breaking a battery and it was starting to break my new Duracell battery (which is great so far). Ordered a SM-900 circuit and after a month I got an SM-A900 (AT&T variant). I realized it had some less circuits in there than the original N900 one.
I am able to charge the phone very well now, which is great but phoneit is not recognized as USB anything,.when it's connected to my computer, (it just charges). USB-OTG is not working too.
I have cleaned the cache and dalvik cache, this is still not working.
I am using LineageOS with Android 7 it works super fast and all of that but I am wondering if this is a HW problem (circuit not fully compatible) or this new circuit requires new drivers with I don't have a clue how to install.
Please can anyone help?
Many thanks!
The new USB flex cable should just work. Tried different USB cables and USB ports?
If the phone only charges on a stock ROM, you'll have to replace it with the correct model.

Yup I tried everything but I tried only in lineageOS RR though!
Doesn't seem like a software problem but you could flash back to stock to make sure.

That is going to be complicated since I don't have USB-data. I think I will put the old one back whenenver I have to or play with SD cards when I have to transfer lots of data.
