Hello, just asking for a bit of advice. I just replaced my usb port on my galaxy S2 although when I plug it into my computer it isn't recognized. I've double checked everything I can think of including the flex cable itself to make sure it was plugged in properly. It is neither recognized on the pc nor does it charge the battery. The microphone works so I'm sure the replacement part is working in some capacity. Would anyone have any advice on this issue? If nothing else I'm going to try and get another replacement sent.

Could easily be a drivers issue/conflict. Click the link in my signature and go to the section for 'if computer won't recognise' and try the things listed there. I know you're not trying to flash with Odin but same thing applies.

I also tried plugging the phone into the wall using a usb converter and it still doesn't charge. I've also tried on multiple computers without any luck. I also took my galaxy s2 apart again and put it back together to make sure I didn't make any mistakes so after trying all these options I believe it's most likely a faulty replacement part and will get a replacement from the seller.

Ah that's different. When you said in OP that it 'didn't charge the battery' I thought you meant that it didn't charge only when plugged into PC. My bad. Hope that you get a refund/replacement without hassle :good:
I reckon you've bought the wrong revision of the board. Did you check the existing board in the phone & see what revision is printed on it, and order the exact same part. If you just lob on eBay & search for 'Samsung Galaxy SII I9100 usb port' there's every chance you're going to get the wrong part.

Spot on there are different rev numbers on the part: 1.5, 2.2, 2.3 and 2.4. You need to make sure that the rev number corresponds with the original part otherwise your mic may not work or you have no signal etc..
I replaced mine not knowing this and don't know what the original Rev number was. I bought the phone in sept 2011 in the uk- does anyone know what the rev numbers were in the phone at this time? Thanks

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.

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.

Just replaced the charging port on my ATT SGII i777. Still not charging. Any ideas on what to try next?
The charge port I bought was for a i9100 but I was under the impression that they were interchangeable:
I've tried several chargers so I'm pretty sure it is not the charger,

Cable? Have you tried a different charging cable?I know it sounds ridiculous but I remember someone posting that fixed their issue.

Yes. Charger and cables. tried like 4 different one including two samsung ones.. I also plugged it into the computer and it is not detected at all.
After my original post, I noticed that my cellular service wasn't working either. Cleaned up the old port with a good dose of rubbing alcohol and a soft toothbrush and put it back in. Charger still not working but the cell service is back.
The markings on both boards say GT-i9100 and rev2.2 but the original says R.B82 and the replacement says says R.B84. I doubt that means anything.
Any other ideas or testing to do? Luckily I ordered an external charger and extra battery so I am not dead in the water.
Just a quick update - I bought several other charging ports before I finally found one that works. The one that worked was on ebay from muchbuy-outlet. I emailed them prior to purchasing. They said it would work and it did. Here is the link will expire at some point...

I think there could be an issue with the i777 firmware which doesnt charge a battery that has gone to complete dead.

It is because the usb port that we have on our phone is not that great. Before I got my port fixed by Samsung, it would not be able to charge an empty battery, but now it is fine. Although sometime when the battery get too hot, it just through the phone in a loop of charging just enough to boot then shut down again.
You need I9100 gt model Rev 2.3 to replace sgh i777 At&t usb flex cable.
I just changed mine. Mine was rev 2.3. I got mine ebay at the "Cellphone-Repair-Shop" Search for "usb flex cable i9100 gt" model. It has to be the Gt model and it has to be The rev 2.3. So ask your seller before you buy. I believe the cellphone repair shop only sells 2.3.
I did put the Non-GT model in first because I read several reviews that it would work if I bought it from a specific store. This turned out to be a misplacement of many reviews. I am returning that one tomorrow. The wrong one charged for a day. Then nothing... and it caused all kinds of reception problems. Pretty much made phone useless.
Now with the Gt model in, when I connect to computer (wouldn't work before) it reads in explorer that this is a i9100 gt model phone. I do believe it is the new usb port that causes this to be read as a Gt i9100 and not the warning screen caused by rooting.
I wonder if this will cause any problems when flashing roms or anything else like otg usb mounting.

Bud,
When I plug in my charger the charging circuit goes on and off. I have a tone that dings once (or makes a "BEDUP' sound) indicating the charger is charging and it sounds like a bell indicating that the charger circuit connects and disconnect even before the BEDUP sound can fully complete! LOL Well instead of just one 'bedup' sound it bedups then bedups again! and again etc. The actual indicator on the battery icon goes on then off in sync to the bedups. I suspect its the dock connector charging port but am not positive. I have two I777's; the second one charges fine with the same usb cable so the cable is ruled out. I also had trouble using ODIN and getting my drivers to load in windows "Intermittently", but only on the SUSPECT I777.
Sometimes I can get it to charge by holding the USB cable either pressed upward or downward but it I change pressure at all it will go out.
Were the actual metal strips on your dock connector worn out? That is what I am thinking my issue is. If so It will require another charging port.
After reading your post an reevaluating my issues I am even more sure it is the charging port, but would appreciate any input you may have about your experience!
Thanks for your input!

Hey, thanks for the info.
My i777 device has the same issue. But the item in the above link does not ship to my country.
So I checked on ebay for another S2 REV 2.3 usb flex cable and found this.
http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=140959296482
But in the cable you have bought it says "R.CB4 28 GT-I9100 REV2.4" and on my selected cable it says "R.CA4 GT-I9100 REV2.4"
Is that a big difference or should I not worry about it?
Thanks!

Sorry I missed this but anyone having this issue should first try cleaning the port with a small brush (soft toothbrush or I used these: http://www.dentek.com/product/144/easy-brush-cleaners/) dipped in isopropyl alcohol. That may help (or not). If that doesn't solve the problem, you are going to need to swap out the charging port. -- Bud

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.......

GT-I9100, 4.1.2 stock. All of a sudden started getting this error when connecting USB cable to PC.
Note, I've been trying two different PCs (one with XP, one with Win7), different USB ports, different USB cable - same error. It charges perfectly fine with all these cables and port, but refuses to connect (Debugging on/off...you name it).
Any idea?
Thanks in advance.
OK......I think you have a faulty USB port (they DO wear out)......
Each connector in that port performs a different function. It is entirely possible that one of the connectors in your phones USB port is faulty (in your case, the data transfer connection) while the others remain functional. It is an easy and cheap part to replace.....
If you check my profile, you will see a guide I have written that explains exactly how to replace it.......

OK, let me understand something - so I need to disassemble the phone first to determine which version my board is, before I even order it, correct? In other words - no other way to determine which version/board I need to order...

hey man,
i had exactly the same with my phone. replacing the usb port of the i9100 helped. i paid 20 € for a new original! one (i think you can get them a little bit cheaper, depends on your location). be careful not to buy fake usb ports from china.
i was afraid of disassembling too. but with the video guide it is simple and easy. the most "problem" i had, was to open the cover. do not force it, be gentle. it takes some time.
you will need a very small screwdriver. you do not need a original from ebay, just go to the next walmart or whatever you have and buy one :good:

Yeah....most DIY chains will do those micro screwdrivers.....hell, they even sell them in my local £1 store.......(though i imagine they're probably only good for a single use lol)

Yes. Checked several cables, including the original that came with the phone. All of them charge the phone (in two different computers) but not connecting the USB (again, in two different computers).
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......

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
