So my phone charges fast only with one usb cable that i have and it is not branded instead a very out of shape cable (left one in photo)
I have other branded cables as well but it hardly reaches even 400mA but those cable charge other device pretty well but not my kenzo
Now i have tried different rom, different kernel , flashed thermal libs but nothing seems to work.
I also have a original sub pcb which was changed due to mic problem and changing to that isn't working either.
So what can be the problem ? is it the usb port ? or like anything else?
It would be great if someone could help me with this please

I do not speak English so I will turn to the translator.
Connect the phone to the computer, if the computer gives an error or does not recognize it directly, it changes the flex that goes from the motherboard to the sub motherboard, what happens is that to have a load greater than 400 mAh the tracks of the data and in my opinion that is the problem you have, the same thing happened to me and with changing the flex it was enough, if the flex is ok then change the charging port that also fails

Well the phone gets recognized and i transfer data regularly no problem with that but the issue is just with charging.
Still i just now changed the flex that connects motherboard and sub board and the issue still remains.
I guess i will have to change the sub pcb and see if that helps or not.

Hi all, I just realized a problem with my Galaxy S2, when I charge it with my AC Adapter (the original one comes with the phone), the phone recognizes it as USB, it shows UTP (or UT... blah blah i don't remember, the same sign when you connect your phone to your laptop to copy file). Not only that, what disturbs me is that the charging current now is USB too, I didn't realize that 'cause I used to charge over-night. But now it has been charge for 4 hours and still not full yet, I download the "current widget" app and it shows exactly 451Mah , I checked on Extweaks's Misc Tab and nothing's wrong, I recheck and restart, calibrated battery, still doesn't work.
Who has the same problem with me and knows a solution? 'cause I can't wait for my phone 5 hours to charge in an afternoon like this
I'm using Checkrom Revo HD 6 (2.3.6), Siyah lastest ver for GB, I don't install anything involved battery or scripts or internal tweaks 'cause I'm no pro
P/s: Sorry for my clumsy English
First of all you should try another charger. If the charger is reported as USB device it is probably defective (at least the short between the USB data lines seems to be missing). The slow charging of the phone is just the consequence of the charger not being detected as such.
I think there is no use changing something on your phone as long as the charger is reported as USB device.
May also be worth checking the USB port is fairly clean? Some GS2's (including mine) have required a new USB port due to false reporting of USB status, e.g. charging symbol without actually being plugged in. Hope you are not in this category!
Good luck
Thanks All, first I dont think the adaptor is defective, 'cause if it broke down, it would not be able to charge at all, in this case it shows exactly the usb voltage charge, it.makes me think it's the fault of the phone.
And I think cleaning the port is a nice idea I havent tried, I'll do it and tell the result latet

So what was the result after all?
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.
Hi,
Having a problem since a few weeks with my s3.
Normally i could connect wiht my phone to any pc,, without any problems. Either it be unix, win, whatever...
Suddnely it stopped working, only thing that happens is charging when i connect it to my pc. Different cables tested, original one, etc..
Connecting it to different pc's resulted in a no go.. so it must be phone related.
No windows pop up, or anything!!
So I figured: Let's install a new rom.
Tried ultima 15 rom, got a different CM rom now (sentinel)... all to no avail.
Is it possible that this has something to do with my radio?
rom info:
android: 4.3
baseband: CEEMG2
Anyone have an idea what to do? Even ADB push ain't working..
See your identical post
I experienced the same problem when m using the Galaxy Nexus S But it was solved by using the app from play store named SD booster... In this app m just set the value of sd card to 1024 give root access and Boom my phone is connected as normal
If this not help then i seriously recommend you to replace the charging port of the mobile through samsung outlet
Go into developer settings, some ROMs may have different ways to get into develop er setting and after you get in make sure USB debugging is enable ^.^
Sent from my SPH-L710 using XDA Premium 4 mobile app
Usb debugging is not required for phone to pc connection see basic faqs and guides .
But as OP has ruled out drivers and cable that only leaves the phone so its worth trying .
Usual replies are
Drivers
Cable
Dirty USB Ports
Not connected to main-board usb port .
I had same issue with my Galaxy SII and when i took it to service center they said mother board needs to be replaced.
So after that SII was good as new.
Got same problem here.
phone is charging over usb , but no data connection (tried different usb cables, different usb ports, different pc etc) but nothing..
also.. tried in download mode and so (after reading forums..) but without success.
then i decided to dissasemble that phone and look, what's inside that beast
cleaned usb port (inside, with contact cleaner), resoldered all pins and etc..
reassembled it back to one piece again and still, no data connection, but only charging
so, here i am, what to do next ? change the usb port on motherboard ?
(visually, everything looks right, good solder points and etc.)
Thanks, Martin

if anybody interested:
i've got it working again :victory:
basically, the problem was the hard way (crap usb data connections on motherboard)
soldered new ways for data+ and data-, and now it's back alive again...
(pictures of ways in attachment)
Martin
see you fixed it already but a note to others :
try using usb port right on the motherboard instead of the case front panel usb ports.....connecting to the front usb ports didn't work for me on some roms, but the rear one always connected so I just have a long cable running out of the back to connect my phone and it works on all roms I've used so far
Nice work hani93, i unfortunately do not dare to desolder and solder this stuff
I've noticed another thing though which is weird!!
When i tried to charge my phone via the power charger (the ac one?), when i check my battery view it still says that i'm charging via USB.
I don't think this is correct, i thought it should say AC or something and when charging via USB port on pc it should display USB?
I think this might be one of the issues that it's also not popping up on the computer.
Anyone know what is causing this or someone can confirm that when charging via power supply it should say something else then USB?
Just confirming your question when charging by PC it says (USB) and when its charging from the Mains it says (AC).
hmmm... guess it must be a hardware issue then?
Either usb port or mainboard... christ...
open it up and cleaned the contacts a bit of the usb port...
Still not functioning..

try to go into Download mode (volDown+Home+Power) and then connect usb, same situation?(eg, no data connection to pc ?)
if nothing again.. try to clean usb port inside (where you plug usb cable), sometimes there is dust and etc. then it stops working.
also, how did you clean contacts on motherboard ? i suggest to take soldering iron with clean bit, and drag iron along the pins.
Whenever i connect my phone with USB to PC (windows 10) , it first alert as connected and then again for disconnected and then again connect and disconnect again and again. SO i am not able to transfer any data as MTP/Mass storage mode doesn't work as PC finally doesn't recognize it .
It's not Software problem It's Hardware one. So all solution related to flashing new ROM /factory reset didn't worked.
Already replaced USB cable and tried on different PC with same results even with correct drivers installed.
So it's fault in USB port , so swapped with friend's Galaxy S2 USB Board completely and again same problem.
I tried when i dissembled it but then there was no GSM network and same usb problem. assembled it back , GSM connection came but again same USB problem.
Though it charges but doesn't connect and shows properly on device manager also. Also sometimes it does detect AC charger as USB , then i disconnect and connect again , then it shows normal AC charger connected.
What's the real problem as even replacement USB board also giving same problem ? Is it problem with motherboard ?
HELP , it's very irritating.
Probably not the motherboard....My guess is the wrong version of the usb board.....There are 4 different 'revisions' of this board for the international i9100.
My guess is you brought the wrong one.

So are you sure it's just 100% USB problem not motherboard ? if yes then i can get it replaced by Local repair shop in less than INR.400 ($5.97) where he will make me sure it works well.
Sounds like a nice deal right ?
EDIT- I just checked the both my old board and the replacement board from my friend's S2 are same Rev no. 2.3 .
But still same issue though his phone might have USB problem.
Can you make sure it's just the USB board problem and motherboard has no role in it. ? so that i can just get the board replaced without any tension ?
My 'gut instinct' is still telling me that it's the usb connector........
IMO, this type of connector is pathetically fragile and simply cannot withstand repeated connection/disconnection over long periods of time. I have owned a number of devices that rely on a micro USB port, and on over 50% of them, either the port or the plug on the end of the supplied charger/connection lead has failed (and I treat my devices with care).
I have never heard of a motherboard causing these types of issues and I've been active on the S2 forums for nearly 4 years, so I've seen a *lot* of posts....having said that, it can't be entirely ruled out....The S2 is now 5 flagship devices out of date, and I guess that those devices that remain in service will start to exhibit new faults that only age can reveal.....
It's up to you if you want to replace the usb board, but bearing in mind the relatively inexpensive cost of the part (compared to the cost of the motherboard), it's as good a place to start diagnosing the issue as any....it's what I'd be doing if i were in your place......

Thanks , will get the USB board replaced and will let you know how that goes ..
actually i have the same issue
i replaced usb board two times and that changed nothing (one was a new replacement, second that i use now it's an used original board )
still can't use my i9100 with pc
most things i can manage without a pc but still... sometimes it would be easier
Hello, a friend is having problems charging his "MiPad 4".
We have tested with several cables and several chargers (including the original 5V-2A), but the charging current does not pass on average 250mAh.
I'm sure it's not a ROM problem because it started to happen from one moment to the next.
I have tried several versions of Xiaomi.eu but it does not change anything.
I'm thinking that the board that controls the charge, where the USB-C port is, may have been damaged.
I'm looking for the replacement part but I can not find it (attachment jpg).
Has anyone had this problem or something similar?
Regards!!!

Hi. My new Xiaomi Mi pad4 has the same problem!!! It's charging speed is very very low and the problem is not from charger and cable ( I have tried 5 different and original and working chargers and cables). I had to open my brand new Tablet and noting was wrong. I'm suspicious if this little board which has the type C USB has problem Since when I connect the Tablet to any PC it says that Usb can not be recognized. Can anyone help me to find this little board on internet?? Or any suggestion???
