Or try to push the central connector up a bit. That may also help add these things are a source of common problems.

already done , but without luck
iam not stupid, i had 3 sgs2 and this is first problem like this,
in service they told me that i have to pay for diagnostic first,( so no good )
iam without waranty, but if i chanage usb port flex cable iam not shure if this one can fix,
as i didnt know about history of phone ( maybe was water damage ?)
but all working like charm, phone looks like new( except USB connection)
so why the USB JIG working ? which pins is connected via JIG?
Also charging is good , some circle can be broken?
i will try to risk order one flex usb connector for sgs2

it cost just 7 GBP free psotage to worldwide
i hope that i will not more destroyed my phone , dissassembly looks no good ...
Disassembly doesn't seem like that hard a job to do yourself. I'd rather do that than pay for it

i did c the same on my phone while chargin
but i did not harm my phone in any way
it jus shows for couple of seconds and den it comes back to normal
yes iam technican engeneer , but iam afraid about that , if i broke some more thing in, than can be more expensive repair
and iam not sure that is this flex cable problem
but better than soldering someting on motherboard

The problem:
I can't get into download mode, when turn off the phone and connect it to USB or WALL charger it automatically boot the phone instead of show the battery charging image
The PC doesn't recognize it (tried many drivers), nothing happens its like I've never plugged it in!!! no messages, no icons NOTHING it just charge
What I've tried:
3 different usb cables
3 different PC (all usb ports)
3 Different galaxy s
Debuggin mode on/off thing
A lot of drivers
Also disassembled the phone to see if something as wrong with the usb port and everything seems in order.
Specs:
Stock 2.1-update1
T959UVKA2
Kernel 2.6.29
ECLAIR.UVKA2
Update 07/21/2012
using the sd card adapter mounted a update.zip called Overstock (It'll have a lock screen loop) but fortunately I comes with CWM and i had a ROM called [ROM][2.2 Froyo][Stock] T959UVKB5 [Deodexed w/Lockscreens+Power Menu] .It has a power menu where I can acces to the download mode but the problems stated above persist.
i cant believe this a hardware problem because it charge normally but this's going me crazy
HEEELP PLEASE!!
Because of this I cant even odin soo I dont know what to do
Early I opened the phone again to check usb port and connections, everything seems to be ok... Installed a ICS ROM called SLIM and have the same problem sooo it has to me a hardware problem T_T but there are no usb port pins loose!!! if nobody have something to add I officially give up here...

I'm not sure what else you can do. For me personally the only usb data cable that works for me is the one from the Tmobile store. I have 2 cables from amazon.com and my old usb cable. None of them work for some reason but they do work with my friends vibrant (weird). If a cable from tmobile doesn't work then the data pins on your usb port could be damaged while your charging pins are still ok( this happens). Tmobile has a 30 day return policy on the $15 usb cable so give that a try if you haven't already. If you end up having to replace your usb port I recommend www.mobiletechvideos.com, lots of users have had success with them in the past.

I had this issue with my xperia arc before. You will have to send it back for repairs. Its a faulty board or connection within phone not cable like people say. When i connected my charger the screen would do stuff on its own like open messages and type stuff :S
Hi All,
I managed to leave my sgs2 charging all night in a small pool of water...
This was about a week ago, and the phone still works ok after pulling off the back cover and drying it out, looks like the water only just made inside the back cover.
Unfortunately the phone thinks it is now always charging and burns through the battery in about 8 hours and the phone is always hotter than usual.
If I plug it into a windows pc, it just says it's an unrecognised device. the phone doesn't recognise that it's connected via usb.
Is this something that could be fixed at a reasonable price at a service center? or should I bin it and buy a sgs3?
Clean the usb port
It maybe damaged I have seen similar reports of phone thinking it's charging and the problem was in the phone port

You can find the part on ebay and replace it: http://cgi.ebay.fr/NAPPE-USB-Dock-C...pt=FR_Mobiles_PDAs_Autres&hash=item3f1a778f7b
As has been said, replace the usb port. Its very simple on this phone.

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 ^.^

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.
So I got this strange problem where my phone stopped charging. I tried diffrent cables, adapters, charging it while being off, charging it via the computer and even tried to adjust the little lip in the micro usb port. Is the charging board dead? If it is, will a replacement be expensive?

Well dude I think your assumption is right.
It might be the charging circuit only which may be dead.
Because as you told that you have tried diffrent cabels and chargers but still your charging is not working which means that the usb micro port through which we charge and connect our phone to computer is damaged and should be replaced .
There are many possible reason of damaging usb port like you may have drop your phone or by using faulty cabels and chargers or if u have rooted your phone then there is possibility of changing the voltage of current to more than 1000 Mhz etc etc.
You should try to flashed a complete stock rom by downloading from sammobile or directly using kies to update or re-flash your phone
you can try that may it may help you.

Nah, it won't turn on because the battery is empty.. I don't have a spare so it seems buying a new board is my only hope..
I saw there are loads of micro usb connectors on ebay. If I solder a new one on. Might that help?

You can try micro usb port which is available on ebay but it would be extremely very dangerous until and unless you know what you are doing.
My suggestion is to give your phone to the samsung care and tell then to repair it.
If your phone is in warranty then they will do it for free. You just need to provide them a copy of bill at the time you purchased s3.
Press THANKS if I helped you
