Hi everyone I wanted to flash a rom on my new S3 but I couldn't beacuse of the USB. If I plug the USB the phone charges but it doesn't recognize it as a phone, in fact it says "Unknown Device" and doesn't let me install any driver. I've tried everything possible: uninstall and install new drivers, install different types of drivers, I've also tried the secret cose *#xxxx*xxxx# (I can't remember the numbers).
If anyone has a possible solution for this, let me know, thank you
EDIT:I've also tried different pc and usb port, but nothing happpened
Try another lead and put the phone in download mode first.
Else you have a fault with the usb socket or motherboard.

I've tried that, but the result is still the same :/
EDIT: please guys, if someone can tell me a method to, at least, root my phone whitout connecting it to my pc, would be great! I've tried framaroot, towelroot and also motochop method, but none of these worked
There is no way to root without using Odin and the usb port.

First of all I am a big-Noob.
My LG optimus one P-500 is in stock ROM.
My Problem :-
Earlier USB was working fine but now
when I plug it in to the AC Adapter it charges OK but when I plug it in to the USB after that it only charges and neither the Phone nor the PC recognizes the USB data connection.
I have tried
1) Power off the phone and remove the battery for a couple of seconds and power it back up, after doing this the USB does not connects. Not even recognised by PC or Phone
2) Device manager also does not detect anything.
3) Uninstalled modem driver and reinstalled USB driver but no result.
Please help
Thanks in advance
Cheers
Request again
Dear mates
I have really very high respect for the forum so please help me out.
ThanQ
Cheers
This happened to me twice before. I had to send it to LG's Service Center because I saw no way of fixing it since the computer wouldnt know what to do with it...
If you have custom recovery installed, you might be able to flash an original ROM over it. This wasn't an option for me before and it seemed like the only way to fix my phone. Don't take my word for it though. Try for the service center first if possible...
Did you try going to settings and choosing Mass Storage only?
Also, change the USB port of the cable with which you connect your phone (plug the cable in another one - try this with all ports if it doesn't work the first time)...
Before going to any service, do a backup and Factory Reset your device, then try again...
Oh, and disable LG modem from Device Manager after installing the USB drivers.
USB not getting detected
I am trying in choosing Mass Storage only.
"Also, change the USB port of the cable with which you connect your phone (plug the cable in another one - try this with all ports if it doesn't work the first time)..."
Not helping either
Disabled LG modem from Device Manager after installing the USB drivers.
No use
Before going to any service, do a backup and Factory Reset your device, then try again...
I will try this definitely but going to service means 3-4 days without phone . really very scary .
thanks mate
anymore help
Okay , I did face this problem before and I did about hundreds of advice from my friends but this is the step that works.
I discovered that this happens when you do crazy **** on your sd card with applications such as titanium backup or root explorer. Curiousity kills the cat.
Firstly you need:
1) Usb Card Reader [Of course which suits with your sdcard]
2) Computer
Firstly, you want to dismount the sdcard from your phone and mount it to the USB Card Reader.
Connect the Usb Card Reader to your Computer.
You should be able to gain entry to the sdcard
Next,clear everything on your sd card then place your sd card on your phone back and do a factory reset. If you don't do a factory reset then you must do it all over again if you decided to connect the usb to the phone. After reset-ing the phone , try to connect your phone to the computer. Congratulations.
Note: This works for me but it doesn't meant that it will work for you , but I think that this is worth the try.

Ur phone charges through usb that means your phone usb port/usb cable is ok. Do this :
Uninstall the drivers, restart the pc and try connecting the phone again. Remember not to install the drivers again. Win7 save a dump of old drivers and i think it will auto detect it. Post results here.

Got exactly the same situation with USB(on different PCs) and also Emergency mode on every reboot(taking battery out for about an hour helps).
Did SD wipe though not sure about factory reset afterwards, gotta try it one more time...

I have tried uninstalling driver and just plugging in with USB but still neither PC nor phone detects USB connection.
I have tried it on Win7, Win Vista and WinXP.
respected mates please help me.
I am on transfer in June so don't want to take chance with Service centre as of Now.

Are you sure you are having the latest driver?
try this:
Code:
csmg.lgmobile.com:9002/client/app/B2CAppSetup.exe
install it,
(you may have to choose language from the last tab, 1st or 2nd option)
and choose P500 from "driver installation"
I didnt experience this issue but if i cant help im sorry.

Try another cable.
Sent from my LG-P500 using XDA App
None of the above methods worked on mine as well - same results on different cable(pc/os).
Will try to flash rooted original firmware via custom recovery, del custome recovery and root and send it to service.
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!
So basically I need to get into download mode as recovery is not working (Beta Testing for Slim and it just doesnt load) so I need to use download mode. But what happens is I connect, and it says this usb device is malfunctioning. It has done that for 3 phones (All samsung, 2 not rooted and one rooted) This computer used to connect fine but now it doesnt. I've tried everything listed in threads, reinstalling kies, installing drivers, uninstalling and reinstalling, all of it. It just doesnt seem to work. I've rebooted between each reinstallation and just nothing works. I've tried all USB ports and tried plugging the phone in while in recovery, download and just regular with usb debugging on and off. I seriously have no clue what to do.
Have you tried a different cable?
You've tried another computer? Different cables? Different ports?

I have no access to any of those except other ports and I have tried all of them on my computer
Well, you didn't give a lot of detail, but from what you said, I would suspect that there is some problem with the computer or connection, rather with the phones. To continue to troubleshoot the problem, you'll need to get access to someone elses computer and/or cables, I guess.

Is there a way to flash stock roms without the use of an EXE? My brother has a Surface but it's an RT
I found a spare usb cable and IT WORKS YESSSS
EDIT: So the drivers installed but Odin does not recognize my device annnnnd I fixed it by opening odin first. Noob mistake.
You were just too excited to think.
Hello Everyone,
I was worndring if it is in some how possible to upgrade my GT-I9070 from gingerbread 2.3.6 to Kitkat or other custumized rom without having to use odin.
I have a problem with connecting my phone to the my pc, my laptop won't regonize it, I think is a hardware problem.
Thanks a lot

Not unless you are already rooted. Does the PC not recognize that you have plugged it in at all or does it just not load the drivers correctly? Best way to tell is to open your Device Manager and plug in the phone. the DM should reload and show something, whether an error or not. If it does not blink out and reload when you plug / unplug the phone, then it's either a hardware issue with the phone's USB port, a bad cable, or bad USB port on PC. And it is possible for a phone to charge correctly, but have issues connecting to a computer if the data pins are messed up. If it IS the phone's port, the repair isn't that bad and could be handle with some patience and simple tools as this one does not involve soldering. You'd need this:

Dude really thankful,
As you say, the PC dosn't recognize that the phone is plugged at all, I try all the usb port on my laptop, different cable, and even different laptop and the same problem keep comming up.
I tried also to reboot in odin mode to see if my laptop detecet anything, but nada, nothing in the DM.
Also, like you expect, it can charge but no data connection, and whene it turned off and I plug it it automaticly turned on by itself.
I pretty convinced that it usb port is screwed.
So, to install a rom my phone have to be rooted!! no way to root it from the recovery mode?!
Thanks again

You can try to clean your USB port of the phone with some compressed air, in case some pocket lint got in there too. Doesn't take much to mess these things up, unfortunately. But yea, I doubt there is a way to root it in the stock recovery as most Samsung phones don't have this option. It'd take less time to just fix it probably then figuring out how to jump through all the other hoops to find a way around it.
I have a samsung galaxy s3 with stock firmware. I've hade a few custom roms before but put it back to stock for some reasons. But now odin does't recognize my phone. Drivers are up to date, the usb cable is the same, other phones are detected (s2 and s5). i have tried other cables including from other s3's from the box. I tried to root it from sd but still no luck, so i can't put custom rom from sd. Is there any way to put a rom from sd without rooting? it can be stock, it doesn't matter(i'm stuck with stock recovery). Also I consider myself a noob, so any explanation would be appreciated. Thank you
No, there isn't. Try another pc or resolve the usb conflict on the pc.

The same thing on other PC's.
I can only suggest following the guide on how to flash with Odin very carefully, then try searching for similar posts that got resolved.
However, most I've read were due to drivers or leads -if your phone connects normally in MPT mode but not in download mode then it's unlikely to be the s3 is faulty.

It charges only...doesn`t connect in any way. Seems like i have to visit a service?
Same here!
Having exactly the same issue here! When connected by usb cable to the computer, theres no USB connection on the status bar. Just the ray symbol on battery to demonstrate the USB is connected.
I need to change my ROM, but even Odin didn´t recognise my phone.
Some clue?
Thanks!
Ps: sorry for my poor English....
Same Problem
I have the same problema, after the installation of the custom Rom, in about 1 week, the PC no regcognize my Galaxy S3. I have test it in another computer with another usb cable. I need help, i need to put a stock rom without odin, i have clockwormod installed.
