Hi.
After searching and testing for hours I don't know how to proceed...
I can't access my phone via USB anymore. The phone isn't detected, no change in device manager on Win7. Only Win8.1 says it found an unknown device.
Quick Charge also does not work like before, but normal charging works stable on every cable.
On the phone, no connection info pops up. I had to set MTP in the developer settings. But it does the charging vibration.
Some testing before, the device was detected in about 1 of 10 tryings, but only with the original cable.
But now, this also doesn't happen anymore.
It worked for about 4 times in a row, after I flashed a 20g flashable kdz over the 20d, but stopped working then.
Could the method that activates MTP functionality be corrupted? (in download mode it also doesn't work)
This all happens between updating to mm and now.
The phone is unlocked and rooted. I use an extended battery and a SD card. A reset didn't help.
The pins of the port look ok. None of the solutions I found did help.
Could the controller or parts of the port be destroyed?
Could my Aukey QC 3.0 car charger do some harm to the device? Maybe when being connected while starting the engine or something like this?
Is the warranty for hardware problems like this void when unlocking the bootloader?

Don't know if that will actually help but just give FWUL a try.

This is a live ISO where you don't need any drivers etc. If you have a physical defect it will not help but to exclude windows + driver issues it's worth a try

I gave that a try but it didn't help.
I am totally confused, which type of (bad) usage could result in such a behavior...
It also do not detect my Flir One thermal cam anymore.
How can I figure out if it is based on soft- or hardware?
im having a very similar issue with my g4 , it charges very slowly and shows charging from a USB source instead of AC when plugged to a charger, quickcharge stopped working, and my pc wont recognize it.
i think the problem is a damaged usb port

Today I was in a repair shop for mobiles and the guy heated up the internal pins of the usb port with a soldering iron to exclude a problem with the connection there, but it didn't help.
Next would be to electrically meassure the external pins against the internal pins, to be sure there is nothing broken. But I think, I will send it to LG to check the device for the concrete issue.
The guy at the service said, it could be that some of the flashs did destroy the function which calls up the data connection and that they can do a complete reflash without using the usb port.
But... he also said that the diagnosted issue could be out of my warrenty due to the unlocked bootloader.
If you want to exclude the usb port as a problem, it is quite easy to change the usb port for someone with a good soldering equipment. The port itself does only cost a pocket money and there are some detailed videos on youtube for this. good luck ^^

Which ROM are you using?
Check settings/connections/USB to PC and make sure to check the box for "enable charging over USB"
I need to clarify more for my dash's problem.
When I use the wall charger my Dash could not be charged, samething with USB connect to PC. But sync to PC I have no problem at all.
my ROM version is 1.11.531.1
Cheap workaround

Try changing your rom or if that fails you could order the Dash Dock for PC with the extra battery charger. THis is a cheap workaround if your dash is not still under warranty. I saw a dash dock w/ battery and a car charger for 18$ the other day on AMAZON

Now I cannot sync with PC anymore (try ur suggestion to changing ROM). Any help to update ROM by micro SD card ?

go to the last panel "settings" scroll left or right till you see, "USB to PC" click on it and remove the first check mark.
plug your phone back into the usb cord.
If I unmark that noway it will be connected to USB port. I did try and no luck
Did you try a new battery?
It seems from most of your past posts you are full of bad luck with phones. If you replaced your LCD screen recently, then you might want to be sure you installed it and all other functioning parts correctly. I believe there is a youtube post floating around that tells you exactly how that should be done.
That might be a reason it's not charging but any feedback helps right?
I agree with the above. As an electrically minded individual, I must say, that you either don't have something connected correctly, OR you are grounding out your system and there is no way to charge this. If you have grounded out your system. Check your internal electrical connections. This is what I do for a living. TRUST ME
Would you give me more details how
I read all of your posts and it appeared that I am at fault for fixing my own phone. Either I have a bad luck or I don't have enough skills to fix my Dash, at least I tried my best and also that the reason I came here for help. Please either help, advise, suggest but if you offer no help just be quiet instead of telling me that I am stupid. I may not know much about the phone likes the last 2 guys but I am willing to learn from your guys.
Since i am on the energy Rom Energy.RHODIUM.21914.Sense2.1.Aug.18, my USB does charge but does not sync with the pc. i can not access the SD neither the phone itself.
how do i fix this?
have you got the newest activesync/wm device centre installed on your pc? and do you still get the screen asking whether to use activesync, usb storage or internet sharing?

I 'm having the same problem as stated above. To anwser your question no, nothing pops up. Please help. I don't think it's a rom problem.
It might be a hardware issue. Try a different USB cable. Also try looking at the USB connector inside the phone with a magnifying glass, to see if any pins look out of place. Different pins are used for the charging as opposed to data (syncing).
Disable your firewall
90% chance this will solve your connectivity issues.
I'm using ESET Smart Security suite, and it's firewall is known to interfere with Windows Mobile phones...
cheers

This. Happened to me.
At one time it was thinking TV-out was connected all the time, ARGH!
I fixed it but still, a lot of times it won't sync but will show up in explorer.
Never had firewall issues, though?

How can you tell if it thinks it's in TV out mode? How do you fix.
I'm having the same issue, within the last few weeks USB for activesync or mass storage doesn't seem to work any more. Charging is fine though, as is the headset for radio.
it happens when you don't have active sync installed. if you have active sync installed try using diff. usb port on your pc.
Go into Start > Settings > Connections > USBtoPC.
Uncheck the box that says "Enable faster data synchronization."
Press Done at the bottom and try again.
Both I and a friend had this happen to us at relatively the same time. I'd read another owner that had RMA'd their phone for this issue and was told it was because of their car charger. My friend and I had taken a trip and had both used my charger, which involved turning the car on while plugged in. We were both under warranty, so we got our phones replaced.
To my knowledge, there has been hardware damage and the data part of the connection will not work again.
Another symptom was that the battery was discharging rapidly. If you notice this, you're probably looking at needing a replacement.

The phone will show a TV-out screen asking you to pick PAL or NTSC video output mode.

What happen here was that the pins got slowly bent out of shape and could not maintain contact and were some times making a short.
I fixed it with some sharp end tweezers and a needle.
So after several weeks trying to figure out what is wrong with my device I came to the conclusion that the USB port on my GNex went bad
here's a few reasons why:
-GNex No longer chargers when plugged in the wall outlet tried several OEM and non OEM USB cables
(but will somewhat charge if the phone is turned off but very slowly and has an error) It shows the battery icon then
it will flash twice the battery charging icon then back to the battery icon with the bolt in the middle and will do that through out the night.
Had a custom rom on there tried changing roms but my computer no longer recognized it and so i've installed removed various drivers
and tried different PC ports and nothing would let it recognize so I manually download a rom on the phone but it wouldn't install.
So I was finally able to odin back to factory stock but that still didn't do anything not only I can no longer go into recovery because it seems to
not have one so I'm stuck and it's getting on my nerves because the only way I can charge it while it's on is plugged into the computer.
I'm my money is that USB port on the phone is malfunctioning so I'm trying to relock the bootloader but can't find a through the terminal, because ADB does not work. Technically the phone still has manufacture warranty. So any help would be appreciated. Thanks guys
Does your computer recognize it in fast boot?
Sent from my Galaxy Nexus using xda app-developers app
I had the exact same issue with an old T989 (T-Mo SGSII). Same symptoms and everything. What got me through the insurance claim was that I told them that the phone was doing an OTA but somehow it failed and it was stuck at the ODIN screen. What really happened was the USB port gave way while restoring to stock which caused the soft brick, but after that the USB port was completely nonfunctional. Try re-positioning the USB cable, the port might be making bad contact with the pins. Other than that, I would just ship it as is since they hardly check that the phones are rooted or in your case, an unlocked bootloader.
No it doesn't recognize it in fastboot or anything it says unknown device. As far as sending it back in I've been on the samsung website trying to request a service repair, but I've also purchased the phone on CL. But I didn't have a problem with it for several weeks so I know it really wasn't a defective unit. Yeah, I thought about reposition the USB cable to no avail.
I didn't think about using that... how did you manage to get an RMA or something to get it replaced
So you can use the device itself fine? Cab you go into play store? Download booot unlocker . it locks/unlocks the bootloader from the phone itself

My apologies if it was in the wrong thread. Yes I'm able to use the phone fine and everything it's just the charging and recognition that's causing problems.
Another question what do I need to be able to open a repair request from samsung or how do I go about it. went to the website but all it does is take me to FAQs?
Well unfortunately boot unlocker won't work because I don't have root and I can't root my phone through ADB or anything like that because like before PCs won't recognize phone at all unless there is a method I can use through the terminal editor
I don't want to hi-jack your thread, but I am also having a similar issue.
I am running CM 10.0.0 but the cell phone will charge, but will NOT connect to the computer. I have tried two different cables and on 3 different USB ports on two different computers. I have the Samsung drivers downloaded and installed. I did not have this issue before the unlock/flash of CM. Is this is a known issue? Is there anyway around it?
I'm starting to think its a USB port issue
If it hasn't been said before, this is a very common problem, it even happens with a few Samsung phones. It's not software related, all hardware, the micro USB port is lousy.
Unless you want to work with Samsung, who, based on my experience, will probably want to charge you "because you broke it", there's the incredibly hard-to-find Pogo Dock or the inductive charging mod, which is actually kinda neat I may do that, I already have all the touchstone stuff...
There's also DIY replacement of the USB daughter board or whatever the exact term is.
In any case, Samsung *might* help you, for a decent fee and 2 weeks' (or more) time.
Yes, try to analyze USB port pins for damage, dirt, bent, anything that can cause a lousy connection (or none whatsoever)

Yeah, I mean I would have to figure something out because I can't transfer files and the only to do it is to upload them to the cloud which is not optimal and real pain.
well out of nowhere USB starting working and charging now normally. So that's cool I'm glad now just to wait till ubuntu comes out.
Last weekend my phone was working perfect then the battery reached 1% i put it to charge and i saw that it was charging but it said 6 hours to charge, which i found strange, i tried multiple chargers, etc. and none of them worked, so i thought that maybe the usb port got damaged because the same thing happened to my old note 4 and i fixed it replacing the usb port but i changed the usb port and it didn't work, so i thought that maybe the replacement was broken too, and i order 2 more from different places, and they didn't work. So I think that maybe is a software issue, I have the OF8 room rooted with AOU Kernel and TWRP and using the engineering sboot but there is no way for me to flash to stock because the phone is not being recognized by the computer as a usb device, so when i connect it to the computer is only working for cable charging. What do you guys think? Maybe i got all the replacement port broken, or maybe the sboot is affecting the port, or worst case scenario, the mainboard is faulty (which i don't think so, because the wifi, bluetooth, gps, screen rotation, everything else works)
Computer USB ports generally cannot fast charge unless it's USB 3.0. The phone doesn't need to be recognized by the OS. Fast charging is different from quick charge, where you will need to buy a compatible charger.
Thank you for replying back. But the issue is not the fast charging with the USB computer, is with any kind of fast charge/quick charge wall adapter. I think that i found the issue, and it was an external battery pack that it was damaging usb ports, because i got a brand new LG G4 and after i connected it to the battery it started to behave in the same way, so looks like the usb port gets broken every time i connect a device to that external battery.
So charging is extremely slow now: max 280mA showing in Ampere app. Tried different cables and chargers(QC3.0 certified), charging speed remains the same.
I can't connect to PC anymore. Windows doesn't even make a sound when I connect the phone to PC. Showing no device.
Headphones connected to USB port are playing only one audio channel.
I've been using LOS 15.1 since last summer without problems, haven't done any updates since. The problem with USB port emerged a month ago and I am almost convinced it's a HW issue. AIDA64 indicates no temperatures over 36°C in thermal section so sensors are working fine I guess.
Anyone tried these charging ports from Aliexpress? Comments indicate that they are not the same as the original.
It really sounds as hardware problem. I asume you already tried with the phone off, and after factory reset and the problem persists.
In my experience, the original lower board have fuses which are expensive and are replaced by resistors on chinese replacements. If you dont want to lose this, try going into a repair shop and have the USB-C port replaced or desoldered/resoldered from the board. Must be done by experienced guy or it will be melted.
I'd buy the replacement board anyway. As long as you don't use crappy chargers, you shouldnt need the fuse too much, and also, the phone have another fuse in the motherboard.
If you have not tried with the phone off, try it. I got the xiaomi wireless charger and it works like crap with the phone on. it disconnects/maintains chage/stops charging A LOT, but if I charge the phone turned off it charges without issues at full power (8-10W according to my USB meter). Maybe is just the firmware being an ass
Thank you for insights. I confirm that hard reset nor charging solved the missing QC3.0 functionality. It's clearly a HW issue.
The whole situation was caused by losing my original charger on a trip and then using certified QC3.0 charger (not from Xiaomi) and unfortunately - cheap Chinese micro USB C cable. I can't stress this more... Never use cheap cables (or chargers) they can literally fry up your port. In this case it was definitely the cable eventhough it worked fine for 5 months.
It seems (from comments) that beside fuses the charging ports from Aliexpress are missing the possibility to transfer data over USB as well. Which is not that crucial because FTP over WiFi is bearable. The real problem that I need to fix is quick charging because with 280mA on Ampere app it takes 5 hours to charge this phone.
The charging port I've bought on Ali is on its way so I will update this thread in a few weeks after inserting it into the phone.
Losing data over usb is quite a problem if you are into custom roms/mods on native miui (which resets the recovery on each update).
Hope that ali's board does have this funcionality. About charging, you can get locally a wireless charger for now, though for me it only charges fast when the phone is idle, using it always just keeps the charge (probably to avoid overheating).
So how the story ends? We're you able to solve the problem?
I had the same issue with my Mix 2. bought a replacement port from Aliexpress and Witrigs.com. As posted on most forums these replacement ports don't support fast charging (in most cases) and no USB data transfer (this is the case with mine).
I had dropped a message on the witrigs.com website to confirm if their supposedly 'OEM' replacement supports data over USB (it looks much more like the original board in the phone that the 'custom' replica one that is half the price).
but I'm not very hopeful of that being the case, given someone has already left a comment on the product page indicating they bought the OEM version and faced the same issue with no quick charging or USB data transfer
Got some problem when i lost my usb travel charger on a trip.
and now my phone was too slow and cant transfer data even if i buy the new authentic from xiaomi store.
i hard reset for 3 times and but no luck.
omg -___-
I know it's old, but I'll let you in on my problem.
I have the Mi Mix 2 and it was happily fast charging until recently. Still the original plug and cable
I have tried all sorts of theories to get it fixed and one person said to charge it while turned off
So I plugged in my usb cable and turned off my phone. Only for it to automatically fire up and go into fastboot. No charging. Just fastboot on the screen
Obviously I can get out of fastboot mode again, but is mine an option change in the settings that needs addressing?
Thanks
