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

Phone Not Connecting to Computer Via USB - HELP!!

i got an S3.. and my computer has xp pro. i had to restore my computer recently from a saved image of my system. before i restored my computer, i was able to connect my S3 to it via USB with no problem. but after i restored it, i'm unable to.
i downloaded and installed the MTP driver, which got my computer to recognize my phone before i restore it. but now its not working and i dont see it listed in Device Manager. whats weird is that when i connect my S3 to my computer, the phone doesnt give any notifications that the phone is connected to USB like it used to before. and it also doesnt give me the 2 options of connecting by either MTP or Camera. all it does is charge my phone. how do i fix this?

Try a different USB cable. I had a similar problem and using another cable fixed it for me.

hi bigtom.. i tried that and it doesnt work. and like i said before, when i connect my phone to the laptop, all it does is charge the phone.. the phone doenst give me a notification that its being connected via USB. and i think its important to get this notification.

Make sure that USB Debugging is ticked.

You also might get the pdanet usb driver and install that in your PC in order to get the usb to recognize an internet access via USB.
You should be able to download the USB driver from PDANet's website.
Just a "maybe" thought. Hope it helps!

i'll take a look at this and let you know..
but i believe the problem is my Windows Driver Foundation driver.. the service wont start. this driver worked to get my phone recognized by my PC before i restored it. but when i try to start the service, i get this error:
"Error 31: a device attached to the system is not functioning windows driver foundation - user-mode driver framework."
does anyone know how to start this service?

Install kies if that doesn't do it then reflash the ROM

[Q] Galaxy Ace II cannot be detected by PC (XP/W7/W8)

Hello, I'm the new guy, kind of (I'm new to this forum but somewhat a technological handyman, so to speak).
I had recently obtained a Samsung Galaxy Ace II, everything was going good on the phone, hell, it's what? Two years old now? Anyway, I noticed the immense trouble I've been having trying to get several Windows PCs/laptops to detect anything from the phone, no driver updates, installations, not even from the trustworthy SAMSUNG Kies application. It is becoming a real problem as I really want to keep this phone, root it, installing several ROMs as I go along, but no, the computers won't even allow me to access the contents of my SD card through USB.
(Note: I have manually downloaded and installed SAMSUNG USB drivers and pooft, still nothing!)
I have tried quite a few methods to allow the PCs to establish a connection with the phone e.g. Dialing "*#7284#*, accessing "PhoneUtil", choosing "PDA" as the good mode, even switching to "MODEM" then back to "PDA"; Uninstalling/Reinstalling drivers; Attempting Kies.
I guess I am on the look out for a new-ish phone to replace this, which saddens me as I love being able to root, install various ROMs, Kernels etc, personally I like this phone too, more than my Spica running ICS (couldn't be too hard though, it wasn't stable whatsoever).
If anyone on this board could find a solution to this problem for me, I would be ever so grateful, I don't doubt it though, I love the work of XDA. Thank you.

Turn off the phone with no cable attached, press volume down, home and power at the same time and then volume up to put it in ODIN mode and connect it to the PC (use windows vista or newer so it auto installs the driver) It should install something like Samsung USB serial device. Tell if it works

Do I have to load it into ODIN mode whilst Odin is running on my PC?

For this test you dont need ODIN on the PC. Its only to see if the PC recognizes the phone

I just tested this and it appears not to be working, whatsoever. Is it necessary to have all SAMSUNG USB drivers installed on the PC?
Thank you for the idea, though. I just really want to root/mod my phone, ugh.

Windows should auto install the drivers. Connect the phone to the PC and see in device manager if there is something like an unknoen device or Samsung USB device

Thank you for the help, although my problem is not dealt with still. I have completed the steps that you had suggested, thoroughly and repeatedly, yet there is no hope for a permanent, or even temporary fix for my mobile.
Windows isn't displaying any correlation between my PC and phone, no driver software auto-installs and no sign of the device being located in the Device Manager, not even under an "Unknown device".
Is this a problem for most Ace II devices? Or am I missing something that is too obvious to consider so seriously?

Porobu once told me something like:
1. Uninstall kies and sammy usb drivers
2. Install kies again, it should promt to install USB drivers.
3. Plug in phone to pc in DL mode.
I'm not sure what you mean in your 1st post so im assuming you have yet to try this. Works for me

When do I plug the USB into the phone and boot my phone into download mode? As soon as the drivers are installed via Kies?

After kies installation complete(dont have to open), boot phone to download mode, connect to cable and plug to pc

It sounds like a broken microusb port but try something first.
Download ubuntu or any other live cd linux distro
Boot it on your pc. You dont need to install anything.
Open a terminal
*Plug the phone while it is turned on to the PC
Write in the terminal 'lsusb' without the quotes and press enter
Something like Samsung android device or MTP device should appear.
If it doesnt appear power off the phone and go to odin mode and repeat from the * the steps

Oneplus 3 does not connect to pc

my oneplus 3 does not connect to my pc. I have tried turning on and off developer options, turn off and on oem unlocking and usb debugging. I change the usb connection to mtp from charging but does not change. Also does not recognize it when i connect to pc. Also does not pop up on status bar and i checked portable devices. I also tried installing the oneplus drivers. i am on Android 7.0 freedomos-2.5. Any way to fix this issue? i might try to update freedomos because im on a old version of it.:crying:

Windows? If, yes windows drivers are the problem.
Try to other pc, to see if it works., first.

I have tried it on both my PC and laptop with both windows 10. Does not work. My PC also has windows 7 still seems to not work. Are there any other drivers i might be missing?

i have also done some research that you should update your drivers from device manager. I dont see anything related to my device. i went to portable devices nothing and i dont have a other devices section in device manager. Any help?

What recovery?
Try to flash latest twrp. I use blu-spark by eng-stk. You can fla**** thru recovery or Flashify app.

ive also found out theres no kedcom driver when i go to fastboot. i even reinstalled adb drivers to insure its there but it does not pop up.

You'll need to remove drivers reboot, install correct drivers, reboot and then be nice to everyone you ever meet and it'll show up. It's a real pain but you can get there. XDA tutorial all the way there!

I once have kind of youre problem connecting to my laptop (win.10). But, at work, on that laptop, connection was ok (win.7).
I reinstal windows 10 and connection works fine, since.
I allways use latest TWRP & version of rom. I can't tell for sure what it's goin on with youre phone.
If i was in youre situation i format my phone (this will erase ALL in youre phone). And if PC still does not see the phone reinstall windows.

Also: Try a different cable.
A cheap cable could have a charging pin layout but lack data pins connections.
9 out of 10 issues with connecting to PC and getting odd behaviours is due to a bad/wrong cable.

What are the driver links if you have? I already installed the OnePlus drivers.

I used the OnePlus cable and another cable.

Driver issues win 10
Find the excellent tutorial here on drivers.
For some reason my phone didn't show up but was able to receive commands. It was frustrating because I wanted to use the all in one XDA product but couldn't.
Even if you installed drivers they can be broken!
Do drivers from scratch per xda tutorial. Don't forget reboot!
Try different cables and usb ports! My front ones never seem to work!
Don't just try fastboot commands also try adb. Like I said mine wasn't seen properly yet it took the commands.
Unless your windows is a years old install it shouldn't require reinstall.
Factory phone reset might help.
Best of luck!

Problem: conecting A5 to Laptop

Hi, I am needing some help. I connect my A5 to my laptop but a pop up from Win10 says that doesn't recognize the usb device. And continue saying that the last usb device connected didn't work correctly and windows didn't recognize it.
I think this happened after installing ADB and some other things like ZX3 to try to unlock my A5 and then uninstalled them, so perhaps I deleted some drivers in the process.
Can you suggest any solution for me to try?
Thanks in advance!!!!

Try connecting your device and then deleting its drivers in the device manager. After that reconnect it and it should show up as normal. Let me know if it helped

No, already tried that. Same message. Thanks!

I tried another usb port on my laptop, and recognize the phone. I don´t know we after some cel phone configurations I lost connection and recognition.
I tried again the first port and touch some items in the developers option, set the MTP protocol and now it seems working.
I stil don´t understand what I have to do to establish a good connection for every time I need it.
Regards.

Hi all. I'm back because I stll have the same problem. Can't connect A5 to laptop. The message says that there is a bad descriptor. It is the 43 error code from window 10. I tried downloading lastest Samsung drivers that comes in an .exe file and installed them. But same error.
Even trying to update the error driver to the lastest samsung usb driver, window says it already has the latest drivers and do not installed them.
Every suggestion from searching in google tried. Don't know what else can I do!!!!
Thanks for your suggestions!!!!!

SOLUTION!!!!!
I was using an old usb type-A cable with a usb type-a to type-c adapter. I tried using the original Samsung cable and it worked!!!!
I can believe this was the problem!!!
Hope I can help another with this! Thanks to all for your support!!!

Hi, I continue finding problems to connect A5 with Laptop. After finding the original problem was the cable, I now use always the original cable.
The problem is that the phone doesn't appear in windows explorer unless I go to developer options and set the USB configuration from RNDIS (Ethernet USB) to MTP (Media Transfer Protocol). After that, a pop-up appears asking for permission for data access. I have to agree with the pop up to see the phone in the laptop.
I think I have to change permissions to granted for ever the MTP. Am I right? Where do I have to set it?
Thanks in advance!!!!

New update!! I have just chat with Samsung. The told me to dial *#0808#. That access the USBSettings options. There I changed the default to MTP + ADB.
Now I no longer need to access the development options. It still appears the pop up, asking for permission, but for now I can live with that!!!
