Win doesn't recognize my Defy

Hello,
I've a big issue, if I try to connect the phone, via usb, to the pc windows none of the devices recognize the connection.
Nothing appear on the Defy. On the Pc, sometimes appear the "new device windows" but if I try to install drivers it show me an alert saying that the device is not installed correctly.
I've tried all the motorola drivers available but nothing happen. I've also tried 2 other pc and 2 other usb cable
Fortunally, the device is rooted and I can install a nandroid backup but I don't know how I can resolve this issue, someone can help me?
Thanks

Enable / disable USB debugging maybe? But normally there should be a prompt on the phone when you plug it in (pulling down the status bar usually asks you what to do, give memory card access, charge only...). Btw, does the Defy charge when plugged in or does the LED light up?

Tried but nothing change. The phone doesn't charge correctly and no prompt message if I connect it to the pc.

And it is definitely not the cable and / or the USB port? Then it has to be a hardware problem on the phone's side I think.

Not the cable and not the USB
There's a way to reinstall all the Defy driver without the cable?

Try installing new moto drivers.

Charging didn't work if I connect the phone to the pc, it's strange because if I connect to the electrical power it works.
I also think that I've had an issue when I've installed the custom firmware

Can't connect my phone to PC

I'm not getting the usb icon on my notification bar when I plug my phone into my pc. It's charging my phone but I can't access it through my pc. USB debugging is on as well.

Are you still on Blazer 4.1?
Try a different USB port. If you are using KIES, remove it and try installing the full Samsung Driver Suite:
http://org.downloadcenter.samsung.c...342248/Sprint_d710_USB_Driver_v1_3_2360_0.exe
If you have access to one, try a different cable as well.
Edit: If you have one, have you tried restoring a backup yet? BTW, you haven't messed with changing your PRL have you?

Try it usb debug off. worked for me.

I had the same problem running cm9 and I tried all the uninstalling and reinstalling of kies and all drivers and nothing worked. I eneded up having to just do a clean install of another rom. I dont know what rom you are on but I would suggest trying that if all else fails.

My phone just won't connect to my PC

I'm running 4.1.1 and every time I plug my device in (With stock USB) I get "USB device not recognized"
I've tried another USB. I've downloaded Kies (Will only connect wifi), I've tried reinstalling drivers, I've tried using another computer as well. I've also enabled/disabled USB debugging,
The USB connection notification only appears sometimes, and even when it does my computer still won't recognize my S3. After I reinstall the drivers my phone does say "Connected as a Media device", but then the notification goes away..
FYI, I'm trying to root, that's why I need a direct connection with my computer so badly.

Does your computer has samsung kies?
You say drivers. Idk what u mean but all we need is samsung kies.

I tried your method a few days ago, and it didn't work. I tried your method again.. it doesn't work.

I had this issue. All I did was get some good ol canned air and blew the dust out of my micro usb port. After that it connects just fine. Was about to do a warranty exchange before I did this.

Its your rom on the phone that's causing this. If you want to rule it out, why don't you just do a nandroid backup and install stock rom or perhaps the same rom clean from start. I had this issue before and it was fixed with reflashing clean rom.

I should probably mention the phone charges will of the USB cables but none of them work with the PC. I can't tell if it's a software issue or internal..

I think it's a computer issue, what was the other computer software you tried on?

Tried it with W7 & Mac, neither recognize the device. Android file transfer just tells me "no device found", and the Kies on mac doesn't work either.

I still won't update my computer from XP cause all I read are device errors with upgraded versions of windows... see if you can get your hands on XP and try. Just as insurance, you have gone through device manager and removed all drivers for the phone and then pushed the proper ones from Samsung, correct?

watch the screen closely when you connect the phone to the pc. does it even recognize thst some usb device was plugged in?
After a few moments, (with the phone still connected) click start,right click on my computer, select manage and select device manager.
are there any yellow question marks on the right side under the computer?
Open the modems (click the + sign) is there any SAMSUNG USB Modem? (should have no yellow question mark)
Open Universal Serial Bus controllers, do you see the samsung Mobile USB Composite Device?
There should be NO yellow question marks or exclamation marks anywhere on the right panel.
If there are, there is a problem with your computer settings/drivers or services.
If you followed my "cannot fail" steps EXACTLY in the order I had it, and did not skip anything, you should be without any problems with the modem connectivity. That includes the uninstallation of any samsung drivers previously installed.
If you do not even see the samsung modem, the cables or the phone may be your problem.
Post your results and I'll help you to get it working. Also mention what your compurter's OS is.

My bad, speed reading is not always good... thanks for pointing that out.
Anyway, did the OP ever get this resolved? Bobolinko's steps are thorough and if that didn't fix it, why don't you just try to go into download mode and ODIN a stock ROM with root injected into it already? It's another option...

Did you try buying a fresh new cable to connect the phone to the computer? I only have those issues with corrupted USB cable and a messy laptop...
Also when that notification appears for me I go to my phone USB section and tells it to mount as storage...and if its on storage I switch media than back to storage...always work for me.

As soon as I plug my S3 in, my computer recognizes a USB is active. In Device Manager, I do not have Samsung USB, all I have is "Unknown Device". I'm not sure what you mean by yellow exclamation point in the bottom right, but there's nothing in my notifications. However, I do get 2 yellow exclamations in device manager. One in Universal Series Bus, and one in other devices

Hi there.
Check this
On calls hit *#7284#
Check if pda is enabled then click on qualcomm settings and see if mtb+adb are enabled.
If not then just enable those.
Hope this is your problem.
Good luck.

I've tried this as well. I get this error:
"Connection problem or invalid MMI code"

The problem is with your computer, and not the phone. You CANNOT get it connected with a problem in the USB settings.
click on the yellow exclamation items and DELETE or UNINSTALL them. then reboot the machine and it should reinstall automatically. If your DRIVERS that are already in the machine are bad, you have to get them updated or replaced. uninstall KIES from the computer, reboot, and reinstall it. go to samsung's site and download and install the driver for your comuter.
The one for the xp is: SAMSUNG_USB_Driver_for_Mobile_Phones_1.4.8.0.exe
install it to your computer and be SURE there is no error while it installs.
then check again your device manager list for any yellow problem areas
connect the phone and wait a while, then, disconnect and wait about a minute
then again, connect the phone, and wait at least one minute. open the device manager page and see if there are any yellow area problems again.
are you positive you have the latest window updates?
you can sometimes right click on an item and do the driver update and fix a problem.
You clear all the COMPUTER END PROBLEMS you have and the phone will connect. That, my friend, you can take to the bank.
Good Luck!
Aloha,
post your results later

[Q] galaxy nexus troubleshooting help please

hi, i got this sgn from a friend with a broken screen, and ive now replaced the screen and the phone turns on and boots up no problem. but when i plug it in to my puter, it says usb device not recognized, one ot the usb devices attached.... as well in settings the wifi on/off toggle starts greyed out, if i go into the wifi setup, i can push the toggle and it says turning on wifi, but then after about 20 seconds or so, it just flicks the toggle back to off. bluetooth if i press the toggle, it instantly flicks back to off, and wont turn/stay on. and the last thing i have noticed that is not right, is when i try to go into the camera, it just f/c's and says gallery has has stopped, yet if i go into the gallery, it comes up. but f/c's if i try to access the camera.. i am thinking its probably a hardware issue, just was wondering if anyone might be able to give me any extra insight or suggestions, thanks in advance.
edit: oh, and the phone charges through the usb port, which i find weird that the puter wont recognize it...

yeah, ive got a usb jig to boot it into odin download mode, but i think i tried it but the computer still didnt recognize it, ill try it again and let you nkow what happens.. also, i have another working sgn here, and i switched out the boards, cause the usb port is not on the mainboard, it is connected by a flex ribbon (thinking it may be a faulty usb port) but either one generates the same results..

You dont need Odin. Just use fastboot and flash the latest Factory image. There are plenty of guides on how to do that. Good luck! If you cant get it to work just let me know.

Go to System Settings -> Storage -> 3 dots -> USB connection, and set MTP ON (V)
and if that doesn't work, try another DATA cable

tried setting mtp on, tried setting ptp on, tried setting debugging mode off and on, tried a different cable, still nothing..
something i did notice was that i have another sgn here and i went to the storage settings, and i was able to uncheck both mtp and ptp and my computer installed a new device "samsung something something" cant remember what the new device was tho..
oh and the bootloader is locked on the sgn im trying to fix and it is unlocked on the second sgn i have here...
could that have something to do with any of this?

[Q] Can't connect to the PC

I have had issues connecting the Note 4 to my PCs. I have tried multiple cables and computers. A usb error appears "Usb Device not recognized" "The last USB device you connected to this computer malfunctioned and WIndows does not recognize it." All PC's are running windows 8. I have tried connecting it via fastboot to flash to stock as well as through ADB and I cannot get anything to read the device.

Are you using the oem cable? Sometimes cheap generic cables give errors. Enable usb debugging and see if that helps. Good luck.

Thanks but I've tried multiple. OEM and aftermakert cables. I found that when I put it in the charger it doesn't detect it as AC. I believe for some reason when the phone is connected to the PC it doesn't switch to MTP, which could cause the issue. I have wiped the phone, tried different roms, and installing plasma kernel. I am at my wits end. I have tried finding sprint's seceret number to dial, supposedly there's a menu to force MTP but I can't find it anywhere.

OK. So I couldn't connect via cable I tried flashing the stock image though mobile odin and now I lost recovery and the phone bootloops. Does anyone know a way to boot into recovery from the external SD card?

I would just flash the OF5 tar and start from scratch. http://forum.xda-developers.com/not...om-sm-n910p-stock-of5-odin-flashable-t3158114

Sounds like it's your computer.
Edit: Any other phone's Samsung or not able to connect? Does your phone charge with any or all of your cables? Hopefully the stock cable.

You need to go to Device Manager and Uninstall/reinstall the drivers pertaining to USB
Uninstall the samsung drivers
After that, unplug your powercord from the laptop
connect the phone to your usb port first and then replug your powercord and turn on your laptop
let the usb and samsung drivers reinstall(auto or manual)(if it detects it normally))

I was able to get my Note 3 to connect with no problem, I was even able to get ODIN to detect it in Fastboot. I have one more cable I am going to try tonight, I have my girlfriend bringing it with her. I may have switched an S4 cable with the Note 4 cable. I hope this is the case.

I was using my desktop, and I tried this on my laptop. Didn't work. Thanks though! I am wondering if this possibly could be a Windows 8.1 issue...
Anyways, 5.50 to anyone who gets this working.

I accidentally switched cables with my son's s4 and nothing would work. Figured it out and then I could connect to my computer. Could be the same thing lol.

I'm on 8.1 pro, and my devices detects fine under cm12.1.
Have you tried going into Settings > Storage. select the 3 dot menu on the top right and force MTP or PTP detection while device is connected to PC / Laptop?
