[Q] Samsung S2 not recognized - USB Device Not Recognized Error - Galaxy S I9000 Q&A, Help & Troubleshooting

I believe the source of the problem to be a faulty install of ICS plus a later rooting, as the phone would intermittently go from Android Phone to Unable to Recognize USB Device, to just not being able to recognize the phone. I've uninstalled KIES along with the drivers and installed them back again to no avail. Can anyone help? Is it possible to flash the phone with a working Android version without using the computer - through the SD card?

I'm having a similar problem seems to be very intermittent and random.
Try plugging it into a friends laptop, mine got recognised that way.
Then either download a rom and chuck it on the card that way or we shall see.
I got it fully working, absolutely perfectly an hour or so ago. Came back to it now and tried to plug it in and no response...

[Q] USB Not Recognised

Hello guys,
To cut a long story short, my cousin wants me to hack is Samsung Galaxy GT i9000.
I rooted his phone in August and it was working perfectly (I play around with my Desire quite a lot) and since then he's tried to get rid of the root to update to official Froyo and something has happened to the USB.
I have tried to install every driver known to man kind to get this phone recognised by 3 laptops and a Desktop PC. 1 XP, 1 Vista and 2 Windows 7. I have been using USB Debug Mode, I've tried it without Debug mode, I've tried every USB slot, I've uninstalled and reinstalled the drivers, kies, even deleted the phone from Device Manager and retried that... and nothing has happened. I can also get in to Download mode but unfortunately the computer still doesn't recognise the USB so therefore I cannot use Odin to flash the phone.
Any help? Cheers
Dan

Are you using x86 or x86_64 OS? Both of these drivers are available at: http://code.google.com/p/insanity/downloads/list -- try 'em?

Tried all that already mate, but I tried again just in case, and nope.. No avail whatsoever. This is majorly frustrating now.
I can access Android Recovery (eventhough originally Clockworkmod was on there, but my cousin has done some strange things to this phone) so I think if I can find a verified signed update.zip, I can install something through that no problem, via the Internal SD Card + "apply: update.zip"?
Oh and another thing, when I put the USB Cable in to the Computer and in to the SGS, the option for Charging, Mass Storage, Tethering etc doesn't come up..
Any light whatsoever?

[Q] "Soft-bricked" Captivate

I thought I totally bricked my Captivate, but it turns out it will enter download mode and after a couple of days I even got the AT&T screen to load up (though nothing happens after that). I thought I could use Odin3 to flash stock back onto it, but every time I connect it via USB Windows recognizes it as a malfunctioned device. None of the Odin programs I use will recognize it now. Is there any way I can get my phone back? Any help is appreciated.
I think you need to install a proper driver.
Delete it please.
The drivers were installed. The computer used to recognize the phone just fine before it bricked. I've been trying everything to get stock back on it...
Try a different computer
My laptop had this exact problem for all of its usb ports
I changed to my desktop and everything works fine now

Replacement I897UCKB2 build is not seen by Windows 7

I have two windows 7 pcs that both recognized my replacement I897UCKB2 phone that I got a little over a week ago. I installed Kies on one of them to upgrade my wife's Cappy to UCKB1. I connected my phone and saw an error that it wasn't recognized. I have uninstalled KIES, the drivers, rebooted, cleaned out Samsung registry entries, rebooted (many times), tried different ports (including on the back), etc - no dice. I tried the other pc which hasn't had any changes and that doesn't recognize it either.
I know the cable is good because my wife's UCKB2 (was replaced as well) is seen no problem using the same cable and computer.
I have tried with my phone in debug and not - mass storage, KIES, ask on connection - etc. I did previously root the phone with SuperOneClick on this build. I was about to flash a custom ROM tonight after waiting a bit but now I can't get any computer to see it although the phone does start charging. I haven't yet tried linux and heimdall but that is about the only thing I can think of at this point.
I started wondering if Kies somehow caused a problem on the phone - maybe because it was rooted? I tried restoring CWM since I have Titanium backup working and busybox, etc. In CWM I tried "reboot into recovery" and then I see the original 3e recovery. I tried "reinstall packages" and it fails the signature verification. I have flashed ROMs many times in the past and have never been "stuck" like this... Any ideas?
I would try flashing the original stock eclair, there is an odin one click around that will do it... "I897UCJF6-final-OCD-REV0.exe". Then try kies mini.

Thanks but that is the ODIN I have always used in the past. It doesn't even see the phone when I connect it though. The phone will start charging but windows doesn't recognize that I connected it.

I had a friend who had that problem. When he plugged his phone into his computer, the phone would start charging but Windows wouldn't even play a notification sound to show the phone was plugged in. He couldn't access USB storage mode or anything. He called Samsung and was told his phone would need to be reflashed. His three button combo didn't work, so we bought a jig on eBay. We could get the phone into download mode that way...but Windows still/I] wouldn't recognize it. He called Samsung again and they replaced it under warranty, without any hassle.
Well, are you sure that you have your usb drivers installed correctly? Have you tried seeing if adb is recognizing the phone? Also, make sure that it is plugged in on all sides on the phone end of the the USB (sometimes the phone charges when it is plugged but unless you plug it in all the way, the computer won't recognize it)
try those...

Thanks for the replies. I know the USB drivers are good because I can easily mount USB storage on my wife's captivate - same exact I897UCKB2 build with the same cable. Additionally, a second pc won't see my phone even though it did before. I have tried at least 6 different ports numerous times. I am thinking I need a replacement.
My question now is that it is rooted with busybox, etc and I can't use an unroot program from a PC. Will a factory reset under settings (not CWM) erase all traces of root?

[Q] Phone semi bricked and unknown device in download mode

Hey all,
I've got a problem related to my Micro USB port (at least I think it is).
[Long story]
I've got a very annoying issue right now. Today I flashed Team ICSSGS RC4.1. Later when I connected my Galaxy S to my PC with the usb cable, no recharging icon appeared and my pc did not react to the connection at all.
Thinking it was a bug in RC4.1 (as OneCosmic RC 2.3 had the mass storage issue) I searched the ICSSGS thread, but not a single issue about mass storage mode was posted. So I flashed Devil kernel, hoping to fix it, but it didn't. Reflashed RC4.1, but problem still persisted.
I went radical and recovered a nandroid backup in CWM of ICSSGS RC3.0 (the one is was running earlier today), but somehow the recovery failed and left me with a semi-bricked phone. (Actually the 2nd time in a row when recovery semi-bricked my phone.)
Only download mode works. Recovery and normal boot bootloop.
[/Long story]
In short:
When connecting to PC to flash with Odin:
-At first the PC did not even notice the phone being connected through USB. Nothing happens.
-After blowing in the contacts of the Micro USB port, PC recognizes connection, but gives "Unknown device" error upon connecting. Reinstalling Samsung drivers does not work at all. Tested on laptop and home PC.
-Somehow I always have to blow into the Micro USB port to create contact and to get the PC to recognize a connection. But that's about it. "Unknown device" every time.
-When I plug in wall charger, the big battery icon appears, but stays grey all the time and after half a minute the phone boots, starting the bootloop.
Could it be that my Micro USB port is broken?
Any solution for this?
Thanks in advance!
I feel so stupid for recovering that nandroid backup. Otherwise my phone would still be working...
you will need the nexus drivers for your comp found here : w w w.multiupload.co.uk/BUCFT8M42 as your samsung drivers are no use now.
Thanks for your advice: Going to test it right away.
Unfortunately your link does not work for me.
I had the same problem but replacing the cable solved it.
Sorry for the duff link http://www.multiupload.co.uk/BUCFT8M42N

Tested this morning with someone else's cable, still the same issue.
Tried the Nexus driver, but still nothing. Also having troubles again to let the usb connection register. It connected after cleaning it, but now it does not seem to connect at all.
Could it be that the phone is completely busted and therefor breaks usb connection?
Haven't heard such a story yet, but is it possible?
I've got it sorted out.
Since it might be helpful for others that are searching for a solution:
1. I cleaned out my Micro-USB port using micro interdental brushes and a few drops of isopropyl alcohol. It also doesn't hurt to clean the contacts of your USB cable, just to be sure.
2. Connected the phone to my PC. This time my pc recognized it as a serial gadget.
3. Disconnected the phone and installed Nexus S driver (because of ICS rom on my Galaxy S)
Next connection my device was automatically recognized as an android phone.
Odin saw my phone as well and I could flash again!
My phone is back on Team ICSSGS RC4.2.
Thanks everyone for helping!
Same Issue cant fix
Hey guys im glad to see others are having the same issue but i cant seem to fix mine.
Assume im an idiot and ive missed something out but ill explain my situation....
Galaxy i9000 - windows 7 32bit - put ics on it a few weeks back following a guide on youtube (had never used odin or anything like that before) got it working but now have no usb comm options in the ics settings. now when i plug the usb (when it does detect at all) it says driver havent worked - device manager shows unknown device - i try update the driver and it says the best driver is already installed.
Im completely stuck and want to revert back to gingerbread so i can use my usb functions again. If i can get odin to see my phone again ill be relieved.
Any ideas?
Cheers guys! Seán.

But most of all, check your usb cable and try switching to another USB port after rebooting your PC

USB connection to PC not working

My phone was working perfectly until a few days ago when I noticed that USB connection to PC stopped working. I was running imilkas CM9 v2. USB used to work perfectly and then randomly, it just stopped working, I don't have a clue what caused it because I did not flash anything on the phone.
When I connect my Phone to the Computer via USB cable, my phone start charging and nothing else happens. My computer does not even show that I connected a USB device.
I've tried 3 other computers with the drivers and the same issue (1 comp with xp and the others with win 7). Also, not to mention, I've tried multiple USB cables, including the original. I've tried USB Debugging on and off, doesn't make a difference.
I've tried ADB and it does not recognize the device either.
In CWM when I mount USB storage, it does not work.
In download mode, when I plug in the cable, nothing happens, odin does not detect any connection.
USB connection to the computer is Dead and it does nothing but charge my phone.
Here is a list of things I've already tried to fix the issue:
1. Factory Reset.
2. Used Mobile Odin, reverted to my Phone's Stock GB ROM (KK2). On stock GB, I tried Kies Air and that worked fine, but USB connection had the same issue
3. Formatted the Internal Storage
4. Removed the SIM Card and Micro SD card, still no luck.
5. re-installed CWM (without pc)
6. Installed Paranoid Android 0.2
7. Called Samsung... They said they wont service my phone because I'm located in Canada and I have the International Note. They told me I'd have to take it to the country I bought it from.
If anyone can offer any help that would be great.
Thanks in advance.

Phone used to work perfectly fine before. Already flashed original rom, it did nothing. And I've already talked to Samsung. They won't help me.
I've already mentioned that in my op! I would be nice to hear suggestions/solutions other than the ones I've mentioned.
Can anyone please help me out with this? I even tried cleaning the usb port a bit more, but no avail. I am guessing the file that recognizes a PC connection got corrupted some how. Anyone know how to update or replace that?
