[Q] Defy not able to connect to my PC via USB

i CAN't connect it with my pc and rsd lite can't detect my phone when i plugged it in!
also, i can't charge it via PC nor the power supply(i have tried using moto's one and a unofficial power supply)
but the most wired thing is i can charge it via an"portable battery"
maybe it is an hardware problem and i can't flash back to my official sbf
warranty is now void?
or can i flash a SBF without connect to PC?
give me a now hope plz

Have you tried the boot loader mode (forum.xda-developers.com/wiki/index.php?title=Motorola_Defy):
---------------------------------
How to get rsdlite to recognise a phone that won't boot
You flashed, something happened, now screen is black, phone doesn't react, u are in a boot loop, rsdlite cant recognize the phone. you're right here.
To get RSDLIte to recognize your phone you have to enter boot loader mode. this means press VOL-UP + POWER If nothing helps, try pushing VOL UP before!' you put the battery in (RSDLIte should be running and awaiting a new connection at that time) If you are using Windows 7, try seting RSDLite to "compatibility mode: Windows XP SP3".

i have tested the connection in bootmenu and RSDLITE not able to recognize my phone
any ideas?

Hello
Please somebody help me. My notebook doesn't recognise my DEFY via USB. More details: When I got the phone it worked but after a while not always. Sometimes it connected 5 minutes later but nowadays doesn't work at all. By the power charger it's charging normally.
When it's plugged to the computer, the phone's screen lights up, but doesn't connect or charge. If I tick on/off meanwhile the USB debug, the USB sign shows up but it's still not charging or connecting. (I've already tried all 4 options)
Moreover when I remove the USB cable, the USB signal doesn't disappear until I restart the phone or abort the USB in the application manager.
I've already tried to install or uninstall the driver (Moto Helper) but didn't help.
The main problem is that if I connect the phone to the notebook, the device manager doesn't see it. (I tried different computers, Win XP and Win 7)
I did a factory reset several times but nothing happened.
I think there was an automatic software update and maybe the problem started at this time.
This is my first Android phone and I'm not an expert so I really need your help.
I wanted to install a new ROM but the RSD lite doesn't see the phone neither in Bootloader mode. It says: "Connect USB Data Cable" and when I connect it says: "USB" so recognises something.
I'm trying to fix it for weeks but I can't find to solution.
System version: 34.177.3.MB525.Retail.en.GB
Build no: JOREM_U3_3.4.2_177-3
Win7 x64
Sorry about my English and thank you for your help.

I didn't mean bootmenu tommy, BOOTLOADER MODDE: press VOL-UP + POWER, try pushing VOL UP before! to get RSDLIte to recognize your phone(RSDLIte should be running and awaiting a new connection at that time)

Hey poross, I guess that your problem seems like a virus activity or maybe a faulty USB cable. Try another USB cable and another PC (with a good antivirus running, indeed!). Before connecting to the new PC, reset your defy...
I just hope it helps. If not, maybe your defy has a hardware problem...

If you are using windows 7 make sure that you installed good drivers for system x86/x64. I'm using RSD on Windows 7 X64 and I have no problems with it. Check in device manager for some unknown devices after plug phone to USB. If system wont see any new device after plugging it wont be driver problem but something wrong with phone, usb cable or usb port. Even if driver fails system should see the phone like unknown device or something.

actually,i am in bootloader(versoin 9.10) and rsdlite still not able to detect my phone =..=
but i notice that when i plugged it in,the phone showed "transfer mode USB"
but nothing happened in rsdlite,no info of device properties.....
what the hell.....

To tommy:
Let's make a conclusion:
1-You have the correct drivers but RSDLite doesn't recognize your phone even in the bootloader mode
2-The charger can't charge your battery
3-The portable battery CAN charge it! (So the phone connector has no problem)
So: It is most likely that you've got a faulty usb cable

Thanks for dealing with my problem
Chamelleon: The device manager doesn't see anything while the cable is plugged but the phone detects something -probably the USB power- but doesn't connect at all. It happpens in the bootloader mode as well so detects the USB cable but it seems that the phone doesn't send sign to the computer. I haven't had any problem with USB detection, connection (except this phone) for a long time.
MMarv: You mean there's a virus on the phone? if it's the situation, installing a virusbuster to the phone could solve it? Which one is a good prog?

I tried with 3 different cables and still not working. With the wall plug charger and the car's USB socket are ok but none of them charges from the notebook.

I mean Virus on your laptop. Hard reset your phone and try another PC with a good anti-virus installed!

So if cable is ok, usb port in pc and phone is ok it must be driver problem. Delete all what appears as Motorola driver including drivers from system32 and then install it again. You can also try to install it on different PC with 32 bit system. Do not install any unknown drivers, just install Motorola Media Link or Motorola Software Update cause if you have this one and some different it can be problem. Or you just have something wrong with system. First try on different pc with drivers from MML or MSU.

Succeeded.
The solution was incredibly simple. It was strange when I did a factory reset (4 times) and rebooted the phone it restored my acccounts, shortcuts, settings. I ticked off two things: settings/Privacy/Back up my data and Automatic restore. Then took out battery then I put it back and began the reset. After it the phone forgot really everything of my details and now the USB is working perfectly.

not working for me =..=
however,i have 2ndinit installed
and after factory reset,the phone is still rooted and 2ndinit still here
so will it cause any problem?

Hey Tommy,
I nearly bricked my defy, and the battery was low too. RSDite not able to recognize it. It seemed that charger can't charge the battery either. But I was wrong. The charger was actually charging the battery. I removed the back cover with the charger connected and the battery in place. I tested the two outer connectors of the battery with a voltmeter (when the battery is in place, they are slightly exposed). Initially the voltage was about 3 volts and steadily increased... Test it if you can. If it is not charging, I bet that it is a phone connector problem. You should return it and I think they can repair it easily...

Hi Tommy1994
First I'm not an expert, this is my first android phone.
My probelm was (I think) an android error. I made factory reset 4 times but it always restored my details. (It's not a perfect FR). After it I did a bit different FR:
-1. in the normal android/ settings menu/Privacy/Back up my data -thick off. So it won't make any backup
-2. swich off the phone
-3. take the battery out for 30sec then put back
-4. press the volume down and hold it while you press the power on button but hold the volume down for more 4 sec. you will see an android robot with an exclamation mark.
-5. press the volume up and down together that's how you enter to the Recovery menu.
-6. first chose the "Wipe cache partition" (you can move with the volume buttons and select with the power button) -wait till "Cache wipe complete"
-7. then chose the "Wipe data/factory reset" - wait till "Data wipe complete"
-8. after these chose the "Reboot system now"
-9. if your phone doesn't want to start just get the battery out for 30sec and take back.
note: you will lose everything of your personal details, installed apps...
note2: it's my FROYO's (android 2.2.2) menu probably yours is different
Sorry for my English, hope you understand though.

hope this helps
If your are trying to connect on windows vista or 7 I think you must be loged on as admin of the computer. I had same problem but when I used windows XP it worked fine this is for rsd lite

going to try ,i really hope it will help
thx

i have flashed cm7 and still not able to connect it to PC
i am quite sure it is not software problem, maybe it is about the USB cable?
is that possible the USB cable can charge but not able to transfer data?

hi tommy1994 ,
i'm having the same problem as you, when i'm in the bootloader screen the rds lite program don't find my defy...
have you found any solution?
Thank you very much

[Q] USB Port Does Not Work When I Hold Down Volume and Power on HTC HD2

Loaded Android on my HTC HD2. Had issues with android, so I went back to Windows. Used the following to load Android
SPL-2.08.HSPL
Radio that support 576 MB RAM
DFT MAGLDR Bootloader v1.13
ClockworkMod Recovery v1.3
Now want to load android ROM again, but USB port will not work when I power on phone holding down volume button. Goes into multi colored screen but I never get USB in the white field. USB works fine when phone is being charged. When plugged into USB port on computer when in Windows mobile, PC does not recognize phone. Searched forums and it seems like a lot of people are having this issue, but no one seems to have the solution to the problem. Was hoping someone could help with this. Thanks!

Are you sure you have Active Sync or Windows Mobile Device Center installed on your computer? You have to have the correct version of this to have the correct drivers on your computer.

Yes, I have WMDC installed. My bigger concern is why the connection will not change from serial to USB when I boot into the multi colored screen by holding down the volume button while powering on the phone. If I have the USB plugged in when I'm booting to the multi colored screen, it just displays a white screen where it should say serial or USB.

If I am understanding you correct if you have the USB plugged in when you boot to bootloader(multicolor screen) it only displays a white screen. Does it x the Sam thing if you boot to bootloader and then connect your USB cable? Also I reread your first post and I see you also say your computer does not recognize the device when you are booted into a Windows Mobile ROM and you plug the device in via USB. Now this is really not good as it might mean your micro USB port on the device nolonger is functioning for data transfer. I suggest you connect your device via USB and then go to Control Panel and open Device Manager and seecwhat your device is listed as there, post it back here in this thread too pleased. I have a feeling though that you are just having a driver issue.

If I boot to bootloader and and then connect USB cable, it stays on serial and never changes to USB. When I plug it into my computer, the light comes on to show it is charging, but the computer never sees it. Even if I scan for HW changes, it never sees the device. Windows doesn't make the sound it normally does when you plug a device in via USB.

I definitely think you are having a driver issue, try this if you do not have a Windows Mobile ROM on your device and see if you can do any kind of data transfer via USB. Try doing some file transfer on your SD card, if you can do this then yes you most definitely have a driver issue. I would then re install WMDC and then boot to bootloader and see if you get the USB in the in the white bar of bootloader that shows you have the HTC Sync connection.

Unable to do any kind of transfer via USB because PC does not see phone as being plugged in when I connect it to the USB. Storage on the phone does not show up under My Computer as additional storage when connected. Attempted to reinstall WMDC and it gives an error saying that it can not install the device drivers. You mentioned Windows Rom, phone is running Windows Mobile, if that is what you meant. Thanks!

[Q] Windows will not recognize Note 3 anymore, help please!

Hey guys,
Just recently, my PC and any other PC Ive tried for that matter will not recognize my Note 3. I had Windows 7 and it worked fine for months, then just the other day it came up on the bottom as USB Device Not Recognized, and no matter what I do it will not do so. Yesterday, I upgraded to Windows 8.1 and still the same result. I have installed Kies 3, uninstalled and resintalled Samsung drivers and still nothing. I am running a custom rom in the stock slot using Safestrap...is it possible that that might have messed up something? Even when the cord is plugged into the PC, the phone doesnt come up with anything notification that it's plugged in, but it does say it is charging. If any of you have any tips or something please help because I am at my wits end.
Thanks

Have you tried with another cord?
Computer doesn't see device... Device doesn't detect plug in... Sounds like a bad USB cord

Yes, actually I have and still nothing...forgot to mention that in the original post.
It's a strange problem which leads me to believe that something has gone wrong in the phone, or that I caused something to go wrong by flashing a rom or three, since it did work previously. Unfortunately, I'm at status: Custom, although my Knox is 0x0.

Yes, this shows as disabled. What should this be?

Can't help you solve your problem, but last night I had a hiccup where I plugged my (17 day old) N3 into my computer in a USB2 port and ... nothing at all. (As if it were electrically disconnected - no "unknown devices" showing)
Tried it in a different USB2 port, and ... nothing.
Tried in in a USB 3.0 port - same computer, same OEM cord - and everything was fine. As far as I knew, nothing had changed on either end of things, although the previous evening I had used a different OTG cable for a USB key with the phone, and I had also had a automatic update of the Samsung Push Service on the phone. Nothing had been plugged into the PC's usb ports since it's prior cold boot. (Win 7 x64 Pro).
This morning (both PC and phone have been rebooted), everything is back to normal - both on the phone and the PC. Both the USB2 and USB3 ports all seem fine.
Ugh. Makes me nervous - brand new hardware.

Boot into Odin mode THEN plug the device in, let windows find the drivers for it then once that's done, reboot the phone regularly and see if it works then. It appears to be an issue with most to ALL Samsung devices, but this worked for my wife's galaxy S3 when the computer wouldn't recognize it and the phone didn't detect a PC connection.

Did you fix this problem?

Thank you! Worked perfectly!

I have the same problem, do you have any solutions ? Thanks.

I too have been struggling with this problem. The is no USB symbol in the notifications area on my phone whether I plug into to my computer at work (Win7) or at home (Win7), using a usb3 cable or a usb2 cable. Its as if there was a setting on my phone that allows recognition when plugged into a computer that has been turned off.Is there such a setting? I would love some help on this as well. Thanks in advance! I am rooted with towel root and have had no problems until last week. When I look in the device manager on my computer it shows :
SAMSUNG Android Phone
SAMSUNG Android ADB interface
I tried uninstalling the above and then plugging my phone back in and it re-installs the same driver shown above.
For what it is worth here are the drivers for SAMSUNG Android ADB Interface:
c:\windows\system32\DRIVERS\winusbsys
c:\windows\system32\WdfCoinstaller01007.dll
c:\windows\system32\WinUSBCoinstaller.dll
Should I be using different drivers ? Thanks|!

please help!
any solution yet? i have same problem, no usb detection and camera wont work i want to flash stock rom whit odin but i cant get the computer to recognize my phone...

I was able to fix the usb recognition problem. i had to do a factory restore. I lost root but gained usb recognition AND the Over the Air update to 4.4.4 and patiently awaiting the update to 5.0 hopefully this month!

it took me months to figure that one out - even microsoft and samsung hadnt got any ideas
its because windows 8.1 has changed the usb stack and requires that all drivers be digitally signed and has an identifer that the bios can read
this means some old usb device didnt work unless they met condition already although new drivers became available for most things but for some reason samsung havent updated their usb drivers in years (May 5, 2011 is last officall release) so im guessing thats why it doesnt fully work in windows 8.1 and im sure the problem is because its not properly signed so the device fails to enumerate unless you do the plugging in another usb device
other old phones work fine like htc and new samsung phones also work fine so its properly just a strange issue with the way the galaxy y handles usb

unfortunatly thats the only solution iv found for windows 8.1 - if you restart the phone or remove the usb cable you have to go through the process again of unplugging cable plugging back in then plugging any other usb dongle in after - its the only way iv found for windows 8.1 to enumerate the device

Hmm, seems hopeless for this matter
Will ask google for this classic problem or bring it service center.

MTP, ADB, PC wont see them, ODIN pc see my phone. Also OTG my phone recognise it.

Hi all.
I need help.
My pc wont recognise my phone anymore. deleted all the drivers and everything.
ADB and USB not working.
But when i put my phone into download mode. my pc recognise my phone again.
But when booted my pc wont see my phone.
My phone only say's he's connected to a charger..
i already checked *#0808#
MTP + ADB is checked.
Tried this on other PC's and same error..
Think something is wrong with mounting data or something?
How did this happen,
i installed twrp recovery + crisscross mod.
After that MTP + adb isnt working anymore..
Flashed stock back on the phone but no results..
OTG is working great on the phone.
Please help
EDIT::
Problem is solved.
I drained the battery to 0%.
Didn't charge for an hour.
Connected phone to PC via USB, in Download mode.
Then flashed Philz recovery.
Reboot to system, and problem's were fixed.

Yes, I have the same problem. G920P
Teardown check after I found the USB interface power supply is normal!
The '1.9 v from The then measured normal tail current 5 v
I ruled out the power supply and USB interface problems
Has not ruled out the mainboard problem
