Hi, this will be my first post here and I'll appreciate if you can point me in any direction which can solve my problem.
I've a rooted SGS2 i9100.
The problems began with the device switching from charging to normal, even when it was not connected to the usb port. Reading other's people problems, I've fixed that cleaning the usb port and gently jiggling the connector.
The problem came back a few times and get fixed in the same way as before. Suddently, the phone stopped detecting the usb charger and usb connection to my mac also stopped working, although the phone did charge the battery while connected. It justs didn't make the connected sound anymore and the battery icon didn't reflect any change.
I tried a couple of fixes that I found in the web and none of them worked. I've changed roms and kernels without luck. I also tried using some keypad secret codes to come up with a hidden menu to check how the USB was setup.
I ended up ordering a new USB flex cable to replace the old one hoping this will fix my problem, but after I changed the flex cable the problem persisted.
I'm currently using RR 2.6.1 (ICS 4.0.4). I've noticed that if I upgrade to RR 3.0.4 with Jelly Bean and not only the problem persists, but the battery stopped charging (I tested with the 3 different kernels) so I've to go back to RR 2.6.1
I can't do anything with Odin, as the USB is not detected, so the only way to change anything is through CWM.
Does anyone have a suggestion? (I forgot to mention that the phone is under an ex-friends name, so I can't send it back to my phone company for replacement)
For starters you can use mobile odin pro to flash stuff.I would flash back to stock and see if anything clears up.

I have also had similar problem on my SGS2.
It maybe your PC you are trying to connect to is malfunctioning or not seeing your device.
What i did was i connected my other phone which is BlackBerry Bold 9900 to my PC via USB and then i removed it & connect my SGS2 & it got connected.

Thanks for the tip. I read about mobile odin, and it looks that it'll do the same as CWM, or am I missing something?
Sorry I didn't reply before, I had an old email setup with my xda account
There are several things you can do.......
If you trust your friend-then let him send the phone back pretending hes still the owner(it says warranty is 2 years).
Youll need to remove all traces of tinkering....lol.
Or change the usb board for $10.

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.

hey guys... I posted something that worked for me...
see my post in the other thread here:

I hope this could work for you too
A month or two ago I started experiencing problems while connecting my S2 to the PC or laptop using the data cable.
When I connect the cable to my S2 on the PC or laptop it comes up with the balloon messages in the system tray:
USB device not recognised.
Then a short while later it comes up with another balloon message:
This device can perform faster.
Sometimes while transferring data, it will disconnect and the file transfer fails.
Sometimes if the cable is moved slightly it will cause the device to disconnect from the PC.
And, of course, the file transfers are much slower than they should be and much slower than they used to be.

I haven't touched any ROM or flashed anything on this in like over 8 months so it's nothing to do on that front.
I removed micro SD card and tried reconnecting again, still the same problem.
I've tried different computers, still the same problem.
I've used different cables, still the same problems. Tried enabling and disabling USB debugging. Same problem still remains.
The USB cables and computer and laptop work fine with my S3.
All the correct drivers are installed for the S2.
I'm resigned to thinking it's a hardware issue as I've exhausted other options. Is there a simple fix or will this need sending back to Samsung?
I've had the phone over a year now but someone told me the warranty is two years?
All help appreciated guys. Thanks in advance.
Why don't you upgrade to ICS?

Probably because his USB port doesn't currently work properly.
@OP, this is often caused by a dirty or faulty USB port. You can try cleaning it, but you may need to replace it.
Try cleaning it out with a dry toothbrush first.
If that doesn't work, take the battery out, and try cleaning the port with a small q-tip with a small amount of isopropyl alcohol; let it dry for a while after that, then replace the battery.
If THAT doesn't work, you'll probably need to replace the part for the USB port.
If your warranty is still good, you could try to go that route, but you'll need to unroot your phone. Otherwise, I've heard it runs about $15 for the part, and you can replace it yourself. If you don't feel up to it, you can have a cell repair shop or Samsung service center do it for you, but it will probably be significantly more expensive than $15.
My opinion based on your description is the USB socket on the phone is wearing out/damaged. The USB socket is on a small circuit board separate from the main logic board. It's easy to replace and the part is cheap on EBay. Search for a disassembly/tear down video and judge whether you can do it yourself.

Thanks for the very quick responses guy. They were very thorough as well.
I will look into cleaning the port and if it still doesn't work I'll consider having it repaired. My soldering skills were excellent but I haven't done it for a few years, so may leave it in someone else's hands.
I haven't upgraded to ICS as I was very happy with my phone at the time. Also, a couple of friends who had upgraded to ICS on their S2 regretted it due to numerous problems, which put me off upgrading.
You can still use mobile odin and theres no soldering needed with the usb,it comes as a board with a ribbon cable.

I've had a look on the Samsung website here:
w ww.samsung.com/uk/support/warranty/warrantyInformation.do?page=POLICY.WARRANTY
It seems as though the warranty period on my phone is 24 months so I might just get it done via Samsung.
I'll contact them in the morning and see where I stand. If not, then the replacement USB board connected by a simple ribbon cable sounds like a doddle. I've seen a grade A condition part on ebay for about £8 delivered.
Thank you once again.

This is a Cable problem. The USB port of your device is wider now, that's why the cable doesn't fit well. Buy a micorUsb cable for blackberry, it's always very full and thick, then use it to connect your phone. The issue should be resolved.
I once had the same problem with my Nokia N8 and using a Samsung cable (which looks fuller and thicker) solved it.
Yeah warranty should be 2 years BUT youll have to unroot it first if your sending it to them.
They may also wipe your phone and stick on 4.0.4.
If you get the board yourself,check the number is going to be the same i.e the spare one I have here is GT-I9100 rev2.2.
Also other people have got a replacement board and the mic doesnt work(think the boards are sold as refurbished).
So its up to you which option you go for.

I've had to sent my phone back to Samsung because it was not connecting to my computer via USB, it charged fine but nothing else, no message came up in the notification bar at all.
I don't know if its an issue the phone has always had as I have never tried connecting it before, it only came to light because I bought a Smart Dock and it would't work.
I've searched on the internet and cannot find anyone else having the same problem and mentioning it being sorted. Lots of cases of completely broken USB ports.
So has anyone ever heard of this issue and know if it was easily resolved by the Service Centre?
Cheers

Hi I had a similar problem 2 weeks ago but mine was also having intermitent problems with the charging connection as well, it would appear that it only takes a minute piece of fluff in the micro usb socket to cause havoc with the connections Sometimes this can be cleared by "blowing in the hole method" this worked temporarily for me but eventually I used a stiff toothbrush to clean out the socket and after that all connections work every time, I have now purchased a silicon plug for the socket and one for the earphone socket as well ( I am surprised that a flagship phone doesn't come with covers for these anyway
I had the same problem as well.
It's just a problem of drivers getting corrupted in your pc. You should have reinstalled them instead of sending the mobile to the service center.

If it was just the drivers then I would still have had the notification on my phone that USB had been connected. And when I dropped it off at the local service centre to see if it could be fixed without sending it off to the big one they tried plugging it in and confirmed it was not connecting.

Standard answers to this question
Reads as no Samsung |USB drivers or Kies installed or corrupt .
Failure to connect can also be dirty / failed USB port on phone / Bad USB port on PC .
Bad USB cable .
Or failed/ corrupt firmware on phone flash stock firmware .
Also possible failing component on motherboard .

I had exactly the same problem as yours i.e no usb icon showing in the status bar etc etc, and all i did was that I reinstalled the drivers using the all in one toolkit for the galaxy s3 and voila! my phone was detected by the p.c again
Maybe your's is a slightly different problem.
Cheers guys,
The problem was there before and after I upgraded to 4.1.2 so I guess that rules out the firmware option, maybe a dirty connection is a possibility but the tech guys on the phone or in the repair shop didn't try anything along those line. I gave it the obligatory blow out at some point but that didn't do much.
I think the guy in the shop was of the impression it will be a hardware fault with the port.
Just hope they don't take forever to get it back to me.
Hey all,
I thought my USB port was broken given that it didn't charge and I couldn't connect it to the PC.
So I bought a nice one and replaced it.... no dice. Still doesn't work. However, the odd thing is, I also bought a USB jig and that does work. Anyone got any clue what could be going on?
Cheers
Maybe the wrong USB board, there's a couple of different ones, best way to work it out is match up with the one already in the phone. Search for similar threads in Q&A over the past few mths; there's been detailed discussions (and pics from memory) of which board is which.

As you said that even after replacing the port.... it didnt work. And it worked out after you connected it to your new USB jig. This means that there might be a problem with the original USB wire which comes with phone when you Buy it. It might even be a problem with the Connectivity Board in the phone as it must have been damaged. I'm not really sure about this but it might even be a problem with software... Maybe you should have tried to atleast wipe the whole system... maybe then you would get to know more about the problem.
Cheers
heh, yeah, I did check that and ordered a 2.2, but they sent me a 2.3.
However, I stuck my old 2.2 one back in, and tried it with the jig, and the jig works :S
So no my USB doesn't work, but the USB jig does... that's really got me confused
EDIT: Yeah, I did think about software, so I tried to install a different ROM and then I got scared and thought I bricked the phone (it didn't like that wrong USB version was there I guess). I'll see how that goes.
I tried a different cable. The weird thing is it sort of slowly died, and I had to stick the cable in at a weird angle and stuff, so that's why I thought it was the USB port.
As I understand it, there are 5 (?) connectors in the socket. Each connector when paired with the common or ground contact (probably the shielding on the outside of the socket) will perform a different task (that's probably an over simplification of the sockets functionality.........but you get the idea)....eg/ data transfer in, data transfer out, charging, jig resetting, usb docking, usb otg.....that sort of thing.
When you get the situation you're in, it simply means that the relevant connector for the required task is damaged or worn out.....but that doesn't mean that ALL the connectors are affected.... ..that is why some functions work while others don't.......

I have an S2 G9100 that developed a peculiar problem:
-It refuses to charge through a variety of charges/ports/cables.
-When connected to a charger or USB port, it turns on!
-Connecting the phone to the PC via USB does nothing. No notification on the phone, no filesharing possible. If the phone is turned off, a notification for a malfunctioning device comes on the PC while the phone [auto]boots.
-In a twist of luck, ODIN is able to see and FLASH the phone via the otherwise useless USB connection!
Tried several (4) different batteries and the behavior isn't affected. (The same batteries work perfectly in another SII)
After a lot of research on the net I couldn't find any really useful info among various good suggestions so I turn to the specialists..
TRIED:
Changing batteries didn't help.
Updating lineageOS 14.1 that was on the phone didn't change anything.
Reflashing the original firmware (4.1.2) through Odin was also in vain.
NOT tried:
I noticed a thread here with the suggestion to remove a capacitor for a similar (not identical though) case but I need to ask around before resorting to such drastic measures!
Bending the flap in the USB port doesn't seem necessary since Odin is working fine.
Replacing the bottom board with the USB port.
Any suggestions and thoughts will be greatly appreciated!

Nice one, should have tried it!
It doesn't work with the original 4.1.2 fw. I don't quite remember if this was officially supported there, do I need to flash lineageOS again to test it?

It should be natively supported as far as I know
But if OTG is broken + data transfer works + charging is broken then I think it's time to change or get rid of that OTG capacitor
Sent from my whyred using XDA Labs
First of all thanks for the fast responses!
This capacitor is there only to provide power to devices connected through OTG? Removing it instead of replacing it will leave me without working OTG but I should expect all other functions to come back to normal?
Do we have its characteristics so I can try to get a replacement?
(Also the broken home button is such a pain without ADB working, getting to recovery is a mission impossible)
no easy solutions for me!
I finally got to removing the capacitor only to find out that the behavior of the phone hasn't changed at all.
Luckily I didn't loose the connection via Odin, so I can still flash stuff to it!
The fact that it turns on when connected to USB charger (while having a battery with enough juice) must mean that something entirely different from what I was able to find online so far..I wish I had a clue how to proceed. Is there any cryptic partition that doesn't get replaced when installing official firmware in .zip format through Odin (AP button)? I'd like to be sure that I have restored the most low level pieces of software.
That a very weird issue. It"s either daughter board damage or a chip that is responsible for charging is fried

Yeah it is. And this phone has one of the most pristine interiors I've seen. No humidity sticker is activated and no visual signs of trouble besides the usual battery corrosion issue (limited on the battery for the time being).
The +5,3 voltage from the charger makes it out of the daughter board and data communication works through Odin so I have nothing to blame the daughter board for, but probably something hardware-wise has gone wrong since it turns on whenever the charger is connected and just reboots if you try to turn it off.
Is there a better way to make sure that we are good on the software side other than restoring the original firmware through a single zip file from Odin? (I have made all the backups I could through recovery such as efs, modem.img etc)
A clean reflash wouldn't hurt. One more thing. Install TWRP, boot to TWRP and connect the charger. I wonder if TWRP will recognise the charger
