I know that many people have issue with connecting SGS2 to PC, and i also know that there are plenty of different solutions on internet, but i wouldn't be writing here if i haven't tried literally almost every possible solution out there. I spent 2 days trying to fix this, but still no result.
PC doesn't recognize that my phone is connected, and on the rare occasions when it does - it just shows me an error with drivers - "Windows can't recognize device" or something like that. Of course i tried numerous times reinstalling drivers, Kies, i tried to connect on 3 different PCs, i bought a new cable today - still nothing (but when other phone is connected with the same cable, its recognized immediately.)
I'm running a custom ROM - XWLSW NeatROM Lite v4.8 (JB 4.1.2), but I flashed this rom several months ago and i didn't have a problem with connection until last month. I also tried several other ROMs, but nothing helped.
I tried to dial *#7284#, then change USB to Modem and then back to PDA, didn't help - the same with *#9090# and setting it to Log via Uart. And of course, USB debugging is off. I'm really desperate, the phone is working fine in any other way, but this is a huge complication for me, so any help would be greatly appreciated.
Also sorry for my english, I'm Slovak.
Hmm, could be a problem with the USB port in the phone. I had the same symptoms and turns out the USB port was damaged so i got it replaced (i has warranty)
Also have you tried if ODin recognizes the phone? Go into Download mode and open Odin. If you see yellow (or blue) box with writing "com:" something than you're good. Otherwise it's the first alternative
I tried Odin, still nothing. Well, I hope it's not a problem with phone USB port - i have a warranty, but I bought it on Cyprus.
Is there any other solution?
I know this.It's a Sammy ROM bug.I had it too on stock 4.0.3.Since 4.2.2 I don't have it.
Well, yesterday I tried SentinelROM v4.75-CM10.1, which has 4.2.2 FW, and still the same problem

I am owner of the Galaxy S2. I updated yesterday to SuperNexus Jelly Bean ROM, didn't liked it. I restored my device to CM9 which i was using for a month without any problems. Then it started, computer couldn't recognize the phone anymore. Its like that SuperNexus broke something i don't know. I reformatted my Win 7 Ultimate x64 and installed fresh new CM10 - but after all my computer and S2 don't like each other - USB device not recognized. Chaos. I asked my friend to come over just to test with his S2 (he's on stock ICS 4.0.3 or 4.0.4), and when i plug his phone into my computer, everything works flawlessly. I tried mounting in recovery, i tried with and without usb debugging, Odin doesn't find phone neither, tried updating drivers - no luck... Dialing *#7284" just gives me "connection problem or invalid MMI code". Need help on this please!
You can check THIS thread. The one HERE , and also THIS thread.
I've read them all, tried every advice, but phone still isn't reacting to anything. So my problem is that phone couldn't connect to a computer, well it connects but it states "USB device not recognized", it charges but that's all. Everything started with Custom ROM SuperNexus. I've done these steps so far:
1. Reformatted my computer OS, which is Windows 7 Ultimate x64
2. Downloaded CM10 over my phone, get into recovery --> factory reset, wipe cache, wipe dalvik, format system, install ROM, wipe cache, wipe factory
3. I tried on my computer, tried on my old computer with Win XP x86
4. My friend's Galaxy S2 is working like a charm with MY cable on MY computer, which makes me believe that there is some defectiveness in my phone
5. I tried cleaning MicroUSB port with tooth pick, ear-cleaning pick (or how do you call it), needle with some paper wrapped around it, tried blowing in it
6. I tried with different USB ports, front ones, USB 3.0 - still no luck
7. I tried flashing Wanamlite and Neat ROM-s, still the same problem
I'm using Airdroid now, but i really need to know what's the problem! I have already ordered a new parts on E-Bay and I'm having high hopes about that solution. Im not able to post link to E-bay item, but search it under Item Number: 150904945773. Any other advice is really highly appreciable. Thank you
Try downloading the Rom over WiFi, or Hardline instead. Have you tried a different USB Cable ? Also I'm not able to check that Ebay # right now.

eBay item is this: New Samsung i9100 Galaxy SII S2 Charger Charge Port Flex Cable Replacement parts
OP, I'm hoping it works for you. You seem to be going in the right direction with your troubleshooting.
Well, i've downloaded this ROM (CM10) via WiFi, now i can do it over Airdroid too. But is there a way to flash Stock Original Samsung ICS in recovery? Or is it only available in Kies and Odin? I came across "Mobile Odin", do you guys have some experience with it, is it safe to use? How big are chances anyway that USB will work with stock ROM? Someone told me "your USB port on phone is OK, if it's charging it's not broken", so I'm thinking that it is not a hardware issue after all? And BTW i used several cables, and three different computers. My girlfriend have SGS3, i tried it like 2 hours ago with her cable on her computer with no luck (and of course her phone have no problems to connect to that computer using that cable). Thank you
I would try a Stock Rooted Rom, and see if that works correctly. If not try connecting the Device, and reboot the PC with the Device plugged in.
How to install stock ROM if i cannot get Kies or Odin to recognize phone? Via Mobile Odin?

Try USB solutions from My Android Solutions or Mobile Odin like http://forum.xda-developers.com/showpost.php?p=28302093&postcount=4789 ( procedure is same but written for Korean SGS 1
Guys let me tell you that I'm grateful to you, cause this Mobile Odin worked and my Stock Rooted ROM worked in connecting with PC. But not on first try when i got into a newly flashed Stock Rooted Firmware, i've let it to do his stuff, update what he needed to update blahblah. Then i tried to connect my cable - it didn't work. I cursed, i cursed so bad. Then i considered to give it another shot, rebooted the phone - and voila! Everything works, i tried 2-3 times and its working. Obviously SuperNexus started my problems, they couldn't be repaired by any other ROM i tried (i tried CM9, CM10, Wanamlite, old Wanamlite with MTP enabler, Neat ROM)... Then with Mobile Odin everything just worked. Dunno what really was the problem. Thank you all
Glad you got it sorted

Well, the day before it occurred to me that I'd like to install a custom ROM, therefore I went on to plug my phone into my PC and for my surprise, the phone didn't pop that MTP warning and the PC did not recognize it.
So I went around and changed USB ports, cables and PCs, same thing.
Decided to try Mass Storage mode, when I press the START button and put in the cable it goes back into the main start screen.
So I went on and tried that *#7284# trick people used since apparently 4.0.3 bugged some crap stuff in the phone, no success either.
Strangely enough I can connect the "pendrive dongle" and it will map pendrives.
Well, I don't have my phone rooted or with SU so that means CWM from app store won't be able to install the recovery module, and I can't install... you get the picture.
Nor ODIN nor HEIMDALL will recognize my phone in recovery mode, wich suggests that the data lanes on my phone went somewhat dead.
Finally, any cable I plug in the phone says it's charging my device, wich leads me to belive that the usb port is dead.
Anyone had this issue?
Anyone can confirm me I'll have to take it to Sammy's assistance?
Sure looks like the USB is dead/dying.
Sent from my digital submersible hovercraft.
So I got one more question, can I root and/or install CWM so I do not stay dependent of the USB to update it or I do need to plug in the USB to install CWM through ODIN?
Several problems
It can be several reasons
1.the usb is dead buy new
2. try factory resetting the device
3. install kies on pc it will install all the drivers that you need
4.your usb port(of the phone) is dead
I had the same problem pc was saying "USB cannot be recognized" I TRIED EVERYTHING from factory resetting, changing pc usb ports, changing usb, changing kernel, roms, trying on other pc, reinstalling kies and drivers but nothing. The problem was in the usb port on the phone where you connect the charger on the phone. That part is weak and so you have to change it. Take to customer service with your warranty and they will fix it without charging anything just tell them your problem and say that you read that most of the galaxy s2 users have this problem and that you didn't touch the hardware of the phone

Warranty has already expired.
Kies was installed on the PC, ODIN gives no info @ COM port.
I wanted to connect it just to root and install CWM so I can swap ROMs as much as I want.
Thing is, the customer service wants 1 week to assess the issue and probably 100USD to fix it.
So for some god-knows-why reason my phone decided to conect to MTP while charging, I quickly restarted it into revocery mode and flashed CF_Root w/ CWM5.5.
Successful!
Bloody USB thingy!
Now I can start messing around with the phone.
Anyone has a n00blet guide on ROMs?
I was thinking about moving to CM 10.1, one of those nightlies running 4.2.2.
This is the one I used >> CF-Root-SGS2_XW_OXX_LPE-v5.5-CWM5
Can anyone suggest actions?
For future you should change your USB-Port. Here we get one for about 15 € (about 20 $) in ebay. It's very simple to change and then you have a full working phone again. Just watch the Videos on Youtube and everyone can do this. Hope I could help!
Hello
I've had this problem for a couple of days now and while Google is turning up plenty of threads and solutions nothing seems to be working.
Yesterday I tried to encrypt my SGSII and but it failed and would no longer boot. So I flashed a no ROM via recovery (there was a notice about corrupted memory) and restarted. Since then I've only been able to access the phones download mode. Most posts with this kind of problem suggest that Odin is required. Windows will not recognize my phone in while in download mode, therefore I can't use Odin. Windows will, however, recognize it as a Samsung SGSII in the device manager if I let the phone boot up and hang at the SGSII logo screen.
The things I've tried so far
Installing Kies
ONLY installing samsung usb drivers
Cleaning the usb port
Rebooting phone and pc several times
Tried different cables
Tried a different PC
Additional info: Last ROM I was running was one of the cyanogen 10 nighties.
Sorry everyone, I know this seems to be a pretty common problem but I'm just out of ideas to try.
So, do I need to buy a new phone? Any ideas would be really appreciated.
Cheers
I put a stock sammobile I9100 xwlse 4.1.2 jelly bean rom on my Galaxy s2 worked fine for 2 days now I have problems charging the phone saying after half an hour its charged when its not also windows 7 will not reconise the device anymore tried factory reset still no joy even when I unplug the charger or plug it in its go's slower to start charging or stop chargeing its annouying the hell out of me tried on windows to uninstall the drivers and reintsall to no avail any ideas
Ok first of all, punctuation - use it.
About the battery problem, it seems like it's out of "sync", you should let it from exactly 0 to exactly 100. That should fix it.
About the not recognizing, have you tried different USB port on the PC? Tried on another PC? Tried with another phone? Tried with a different USB cable?
You have many options, now go try them.

I am having a similar issue, when I plug my phone into a windows PC through USB the MTP driver is buggy, have to reconnect and change to media device a few times until it installs, and then the issue afterwards will be the phone will seem as if it is being plugged and unplugged multiple times after its been disconnected (usually when I have media player running too) ... this issue was non-existant before the software update so I'm sure its gotta be an issue.
comas & latest kies.

The thing is that it doesn't make any sense
You are not rooted are you?
Your usb flex must be dusty/busted.
Nope not rooted tried uninstalling drivers and reinstalling even tried Keis not a thing I get error code 43 on my pc even though the drivers are there it says usb device not reconised so for some reason which is doing my head in I cannot get it to connect with my pc on windows 7 also tried it on another computer with XP on and get the same problem tried driffrent usb ports and usb leads as well
Error 43 is a start.
Disable the antivirus and don't install the drivers, install kies.
Try a laptop.

Hey guys,
A friend of mine was having some trouble with his S2 which was running Omega rom v16.2 (phone would say it was charging with no cabe in it etc), so i told him he should try updating to Omega v23 Final and see if that fixed the problems.
However, after installing Omega v23 Final, he was stuck at the bootscreen, i told him it the first boot could take a while but it was stuck at bootscreen for a couple of hours before he gave up.
He tried everything, he wiped everything in recovery (system, cache, dalvik etc) but the problem persist.
So i figured i would flash the stock android rom via odin since nothing was working,
But the problem is that windows does not recognise the phone, neither does odin. (he had this in the past on old rom, it would recognise for some time then it wouldnt and so on)
it tries to install but fails every time, i tried installing several different drivers ( kies, and different stand alone driver packs) but i could not get it to work.
So, does anyone happen to know what is wrong?
Help is appreciated!
edit: odin does not say anything, windows says the usb device could not be installed
Tried several usb cables and ports, without succes
I think Debug Options wasn't enabled.What does Odin say?
Edit:Your USB is bad! If it says it's charging w/o a cable,it means bad USB...Try to lift the tongue(The metal part inside the USB port)with a toothpick.
And you could also try another usb cable as well as another usb port.
