USB help required - Galaxy S II Q&A, Help & Troubleshooting

Hi,
I hope I'm posting this in the right section.
I have a rooted S2, with CheckROM V6 installed and the Siyah Kernel (v 2.6.3). Earlier on today I was playing around with settings in Voltage Control and ExTweaks and to improve battery performance. This evening, I plugged in a USB cable to transfer some files between my laptop. However, when I plug in the cable it is not recognised by the phone, it neither starts charging nor does it show prompt me to mount the SD storage. If I plug the same cable into the plug I am able to charge the phone as normal, so it does not appear to be an issue with the cable. I have restored a proevious backup as well as re-flashing my ROM and doing a factory reset, none of which have made a difference. Has anyone experienced this before and able to provide some advice on what I could possibly do to enable USB charging or file transfer?
TIA,
Joseph

Bizarre
Thoroughly bizarrely, it appears that this was all random coincidence. I tried another cable and it works fine...strangest thing is the original cable worked fine before I started tweaking!

[Q] Fasc. not recognizing USB

My dad had installed the gingerbread leak but was complaining about random reboots, so he gave me his phone to bring back to fro-yo, I backed everything up with titanium, and I successfully brought it to ED05, but now the phone does not recognize being connected to USB, and my computer cannot see it connected.
I cannot Odin anymore because computers do not recognize it, I have tried uninstalling the drivers and re installing, but that did nothing. I was hoping at the least that I could root and restore all his apps and data, but I can not do that either, because I cannot use Odin or SuperOneClick, and Z4 or Gingerbreak do not seem to work.
I would appreciate any help, right now i am puzzled. But I guess at last resort, he could switch phones with me, and recover everything on my fascinate.
Did you make sure that the settings are correct, like USB debugging checked, etc. Mine had that issue too until I fixed those.
I had an exact same problem with several computers. Once I replace the USB cable to new one, it works fine. Bring to Verizin store, they will replace it for you.
The samsung phones are very picky about usb cables. Also you will find alot of USB Cables are not "sync" cables, but for charging only. Target sells a USB sync cable for $6 (last i checked). Also, i have heard (but not verified) that if you go to walmart at each cash register on the candy rack there is a cheap usb car charger for $4 that has both micro and mini usb connectors. This charger consistst of a DC car adapter and the usb cable and have heard it will work for sync if you are broke and cant afford a better cable.
Use a different computer.
The same thing happened to me a while back. I installed the drivers on a different computer and used the cable that came stock to put files on the SD card so I could flash a different ROM and that fixed the problem. You can also connect your device to your computer and put the files on your SD card and swap the cards on the two devices. Hope This helps!

[Q] Problem with USB port and function

Today i found out my SGS2 have problems charging the phone, not only that. i also have problems with USB file mode, and keis mode. and if the phone is turned off. i only once got it to charge without booting. else when i connect the USB it boot the OS.
What weird thing is, that ODIN works without problem every time!
The problem appeared after upgraded to Darky Rom KG6 with jkay mod. but don´t think it has anything to do with that.
I reflashed to a Stock KG6 (still same problem)
From OS restore to default, and format (still same problem)
tried to flash back to KE2 stock. an but on CWM, and clear battery stat, and system cache.
flashed backup with a KE2 Kernel (still had the same problem)
What i found out is that, when i disconnected the wall plug charger, the phone still was in a state of charging. and it don´t give the sound notify when attaching the USB. but when touch the USB cable it suddenly charge and give the sound. but it can also go in MTP mode. or start Voice recognize.
Could the be a faulty USB port on the phone, or can Battery State and kernel updates have something to do with this problem?
im now pretty sure this has something to do with the USB port. when i just spoke on the phone. it suddenly began to change between Car mode a normal.
i than tried an alternative why to deal with the problem. I tried with a hairdryer after taken out the battery, sim and sd card, and carefully heat the back of the phone.
for 5 hour there has not been any problem. both the desk dock, and wall charger is working.
got a dejavu from the xbox days and RROD.
I have the same issue. I think the USB port is faulty.
The phone reacts to different electrical resistor values on some pins of usb port that triggers car mode, desk mode, etc. So, somthing is faulty in the usb board that reports to the system that has something connected to it: charger, car dock, desk dock, usb jig, etc.
I can't find any solution on the forum, I tried with several roms and got nothing.
So... I'm waiting for a USB Jig to reset counter, back to stock rom and send it back to store for warranty
My problem seems to be fixed by using the hairdryer on the usb port. I think the problem appear from the why you hold the phone and if your hånd become sweaty. Because there are nothing to protection the usb port like the sgs1.

USB cable connection not working!

Hello, i am new to xda-developers, so please have patience with me
I was using my original usb cable to charge my phone from my laptop. But one day some strange things started to happen, when my phone's battery was completely depleted i connected the usb and phone started turning on and off very often and I wasn't able to charge it even a bit. When connected to wall socket charger everything seems to be fine, it's charging.
But now the usb is not working, neither computer sees it (before i used it), i used other cables, no good. Now it's original ginderbread ROM, maybe i should reinstall it, but i can't do anything since usb is not working in any way.
Maybe someone of you had similar problems and know how to solve it?
Thanks in advance!

Thanks for the quick reply!
I tried cleaning it with Tooth Brush and even used special liquid for cleaning electronics contacts and corrosion removal, everything seems to be clean. But still nothing happens when connecting to laptop.
P.S. Same cable is working when charging from wall socket charger, so it seems the contacts must be clean and intact (at least power supply contacts), so maybe it should charge from laptop?
P.S.S. I forgot to mention, when the phone's battery is depleted, when i connect to laptop, it doesn't charge but in time phone becomes hot. So maybe this would prove it's a hardware problem?
Try different laptop USB port. If this doesnt help than probably your data cable is faulty. Just replace it with another one.
I think Your phone is fully operational if AC charging without any problems.

I have already tried different laptop ports, even different laptops, already tried with different cables (which all functioning properly with other devices and all are marked U2). I am pretty sure that's not connection / cable problem.

Honor 7 PLK-UL00 and B341 Device not recognised and its only charging

Hello all,
Honor 7,
PLK-UL00
B341 and EMUI 4.0
Android 6.0
Im unable to use my phone as USB Mass storage device. When i connect my phone to PC sometimes im getting as USB device not recognized and sometimes im not. I tried different PCs and different cables. ITs ONLY CHARGING
tried cleaning the micro usb port, uninstalling and reinstalling drivers in Pcs but it didnt work.
I switched off my phone, removed mem card, reinserted it, swithced it on again, connected my phone to PC(in sleep mode)
phone is detected as storage device and got notification in notification panel to select as charge only/files mode/ photos mode.
After ejecting and removing cable again back to issue. No detection. OTG also not detected. No Data transfers are being made but its only charging( even through Car USB port)
Anybody facing USB not recognised problem ? i hope its software related.
could anyone let me know of solution.
Thanks.
I am also facing the same issue
I thought I was alone in this issue.
Basically, my problem is, the wall charging and USB connect are reversed. i.e., I connect my wall charger, its showing as USB mode and when I connect the cable to a PC, its showing as AC Charging. I tested with Ampere app and when I connect to AC Charger, it is drawing only around 300mA(like it would do if connected to USB) and its drawing around 1.5A(like it would do when connected to wall charger) when connected to USB PC.
I have been having this issue for quite sometime and recently, I had upgraded to Marshmallow through OTA upgrade. I thought atleast this upgrade would fix this issue but I am still facing the same issue. I even contacted the customer care and nothing useful advice other than restoring to factory settings was suggested(which I tried and didn't work).
I guess it should be some software issue but don't know what it is or how to fix it. Any inputs would be welcome.

S6 Edge USB connectivity problem to PC (Only Charges no MTP)

So as the title states. I am having problems with getting MTP options while plugged into a computer. It sometimes works and others doesn't but it seems to work once on a first try on a new system and then the next connection it is only charging.
I was thinking maybe faulty port or cord. As I have tried several cords which also work on other phones I ruled the cord out. The port I have tried unplugging and replugging several times with no success, also jiggling the cord a bit while plugged in. No luck. It just randomly works fine once in a blue moon and then does not.
I have made sure my phone was unlocked, switching options in USB configuration setting though not the notification option because it is not there while it is not working, USB debugging on/off, restarting the phone, simulating a battery removal reboot, installing windows drivers, removing the sim card.
The phone is rooted with a custom rom for marshmellow. Can't really reset it or flash it without a computer to my knowledge. Was considering trying out Nougat but with the current situation I am not really able. Any help, ideas or insight would be greatly appreciated!
