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

did you try to make a backup of your contacts on your SD card and do a factory reset of the phone. It might be some setting. It happened to me couple of times on my HTC while working with the HTC stock ROM.
If it didn't work you might try to follow this guide

I am having the same issues. I have 2 of these phones that are doing the same thing. Both have been rooted but NO new ROMS have been downloaded. Both phones worked fine with the stock USB cable until 2 days ago & I haven't been able to get either to be recognized by 2 seperate computers. One is Win 7 32bit, the other is XP. I can get them to show 2 portable drives; however, when I click on either, or try to drag & drop in them, it tells me to insert a disk.About to go ape crappers! HELP!
I have this exact same problem on my Infuse: USB port works for charging but the computer doesn't recognize it and the device acts as if I plugged it into a USB -> AC power adapter, and when I bring up the camera it's just a black screen and controls that don't do anything. I just tried resetting to factory defaults, even rooted it and flashed to another ROM (ZEUS) and it's still having the same problems. I'm just wondering whether it's a hardware or software problem. Anybody figured out a fix yet?
Hi,
I have a galaxy s II i bought about 8 months ago in germany, It worked great with 0 issues, ive moved sevrel roms and never had a single issue.
last week I updated to the JB preview CM10, MTP worked fine when I connected it to my PC and I had no issues other then the occasional reset.
anyway, this Friday I was using it as a modem, USB tethering, when suddenly it stopped working, I unplugged it, tried another port and I get unknown USB device, I thought maybe it was just a temp issue, but I reset, re-installed drivers, and still nothing, my PC runs windows 7 64 bit, I tried at work with multiple cables and windows xp on multiple PC's, also tried ubuntu, nothing...
I tried that USB code thing i think its *#2738# something like that to switch between modem mode to USB and still nothing...
weird thing is it charges fine, the connection seems to be good and its not loose... im starting to think it got static or something cuz in my days as a PC tech I saw this happen many times with USB Flash drives, the contacts would get static and they would go...
any ideas?
P.S I tried re-installing kies, and nothing...
any help would be great! thanks!

I would try on another PC first. If it works, the phone is fine so far and there is something wrong with the PC.
I have same problem. I almost tried everything (uninstall and reinstall usb drivers and kies, uncheck usb debug, different pc or cable, reinstalled firmware...) but none of them worked

I've tried all the above suggestions, 4 cables, 4 PC's, 4 OS's, Uninstalling and reinstalling on varoius computers (drivers and kies), samsung codes on the phone to switch from pda to modem and back to pda, flashing stock rom, formatting all cache and data... Im looking if there is some advance trick im missing, I think we can all agree that this is not an external factor like cable or computer, its like my data contacts on the socket are dead and only the charging is working.... has anyone ever heard of this? or maybe there is something on the phone that I can flash that i havent that doesnt get flashed during wipe, stock format?
the annoying thing is this phone was bought in germany and i live in israel and there is no warrenty here, it means I have to wait for someone to go there to fix it...
I mean for now I can copy stuff using a micro-sd adapter but its super annoying!
if anyone has an advanced trick that worked for them it would be amazing! if not ill just have to accept my fate

then it can b a hardware issue .. either usb port issue or a motherboard issue
u can try changin ur usb port ... u can order 1 from ebay and fix it urself ..
I've had the same issue but because of water damage
on another note, Try cleaning your port with a soft tooth brush.
YES!!!
Fixed it! it was so stupid yet no way of knowing,
so i almost ordered the flex cable but said I'd clean the inside first to make sure its not the issue, I opened the back case and while cleaning I noticed a ribben was loose, lol, i just popped it back into place and walla, worked like new!
thanks for all your help, my phone is back to working great

Hello all, I have a GS3 international GT-I9300
I'll try to go through the story as fast as I can and give as much detail so you guys can understand how I got here.
Bought the phone unlocked, I was stock, I rooted and then I decided to install a new ROM. I went with Resurrection Remix, it was working great. I did this on a desktop back home. They released a new update to RR so I did a OTA update with "Update Me" apparently the thing flashed but it didn't, the phone still worked but NFC wasn't working as well as having lost root access and some other stuff wasn't working correctly, but I lived with it.
I moved to Florida (home is in NY) and I have a laptop with me, for some reason my laptop used to be able to transfer files to my S3, but it wasn't doing it any more after a while. So it would just charge it. I was in a hotel room last week trying to tether via USB but the PC wasnt having it, it could not locate the phone. This week I moved to a different hotel with internet and decided I would flash stock on my S3 to get rid of all these bugs and get root again, I tried flashing stock through recovery and it wasn't going, so I tried flashing RR again (this time downloaded from the site RR site) and it worked. Still no USB connection but I had root back. I looked around my PC and apparently the Samsung drives are not installing or something on my PC. I installed Kies, but nothing, I tried a stand alone driver install and nothing, so I just gave up and bought Mobile Odin pro from Gplay to try to flash again.
Mobile Odin for some reason (I blame it on myself) wasn't finding/flashing stock so again I decided to try and flash RR and see what would happen. It flashed RR and turned on fine. Then I just decided to look for an NFC fix on XDA. Once I found my NFC fix (http://forum.xda-developers.com/showpost.php?p=32029713&postcount=8367) I decided to just copy the files to the system folder, NFC still not working, rebooted and NFC still no working, so I figured I would try to flash the fix through mobile odin seeing as how I can't get my PC to pick up on the USB. I tried flashing but MO just kept bouncing it back and re-booting into RR. Tried again and no flash. So I decided to again try and flash stock. I tried going into Recovery, the phone shut off like it always does, came back on but stayed in the Galaxy S3 GT-I9300 logo and would not move. I shut it off again, tried turning it on again and still stuck on the galaxy logo. Now, if I leave the phone off and plug in the USB, it won't show the battery charging image, it will actually turn straight onto the galaxy logo again and stay there. I can get the phone into download mode, but like I said my pc won't recognize the drivers.
Now, here are my questions:
What happened?
Can this be fixed?
Am I an idiot?
If I can get the drivers installed on another PC as well as Odin (1.85), will the new PC "see" the S3 or are the drivers on the phone deleted as well? (if that sort of thing can happen, idk.)
I'm going to see if I can borrow a buddy's PC and download the drivers as well as odin to try and bring my S3 back to life, I just want to know, what happens if I can't get the other PC to pick it up ether because the drivers on the phone are deleted (if that's a thing) or what I can expect if it is connected.
What are the steps or guides to follow here? I just got it into Download mode and it says on the top of the screen:
ODIN MODE
Product name: GT-I9300
Custom Binary Download: Yes (2 counts)
Current Binary: Custom
System Status: Custom
sorry , i am sometime getting headache reading long english text so i just briefly look over.
your PC doesn't recognize your S3 ? is that correct ? hmmm , is it possible that your PC (Microsoft Windows I assume?) system is damaged due to something like virus or some reasons ? i have encountered that kinda problem before and be OK after i reinstalled the system.
If it's a soft brick, then it can defiantly be fixed. You might, however, lose your data along the process.
Be glad it's not hard bricked
It happened to me many times, USB error "unknown device" connected. Only fix for it was reinstalling Windows so better if you can use different PC or laptop. Install Kies and other USB drivers. Restart computer, download and run Odin v 3.0x. Flash your phone.
If this doesn't work then maybe your phone have a problem with USB port?

Thanks for the replies guys. I'll try to fix tit today, I didn't get a chance to do it last night. If anything I'll update you guys with what's going on.
Like I was saying, I'll try using a different PC to fix it. Now, if I can't get Odin to recognize the phone, what would be the next step?
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.

Hello guys, I have this problem. Recently my apps stopped updating ( I think Playstore and Google Services updated and made that happening...idk) and couldn't access most apps, then began to restart 4/5 times in a day automatically, and couple of days later just showing the logo after turning on. So I decided to update the OS but as it's rooted it wont let me. I used to have 4.3 version (don't the name, maybe Pineapple Pizza) so I decided to start from scratch after backing up everything, took note of version in my country, efs, etc). Made a wipe clean through TeamWin, and with Odin tried to make a new install ( Stock).
Unfortunately when connecting to my pc can't recognize device "“USB device not recognized”.
I tried cleaning USB connector with dried toothbrush, other ports in the back. With other 2 computers and same result.
Installed Kies but didn´t work, unistalled Kies and tried latest versions of drivers for windows 7, same result. Tried Samsung latest drivers ( older ones), didn't work either. I have tested other devices in the USB ports and they all work fine. I thought it might be that I didn't selected "USB debugging mode" before the wipe clean...or it wasn't a Wipe Clean at all...(?).
I checked most of simmilar problems in the forum, but I couldn't find a solution, sincne I can't even access my phone.
So, Im here with my oldie S3 in some kind of "limbo"
Any ideas that might help?
Thank you very much in advance! and sorry if Im posting in an incorrect forum.
