Problem with connecting X1 to computer - XPERIA X1 Q&A, Help & Troubleshooting

I have bought a Xperia X1, but I can´t connect it to my computer running Windows 7. When I connect the phone to the computer it starts to charge. The computer does not see any device. I have tried to install Windows Mobile Device Center, but it tries to install drivers and then it stands "The device is disconnected" or something.
When i have looking around on the internet, I have realised that there is some kind of CD with something to install. Maybe I need to download that stuff? Please help me!
(Sorry for my BAD english)

Try this program USBDeview and see if your windows detects anything when you connect your X1 by a USB cable. If not, then try another cable because it could be broken, also try different USB slots. Well you say that you have tried to installed the Windows Mobile Device Center and USB drivers, so there is nothing more on the CD that you need or anything that you cannot download from the internet

I have not tried to install USB drivers manually, it is just WMDC that tries to install them but fails every single time. Can you please link to them (the drivers)?

So do you think that the problem will be solved by buying a new USB cable?

[SOLVED] N1 Brick

Question...
Just upgraded my primary comp and i wanted to mount my Nexus one to try a new kernel.
I plugin the cable but all that happends is that it charges the found, i have no option to mount?
So i look under usb devices at my computer and finds out that it has a "Windows error code 43".
I try and connect it to another computer, its the same.
I just bought 2 new cables, same problem.
OS: Windows 7 64 bit
My Nexus is listed as "Unknown Device" with no option to install the x64 driver.
So my question is... did i brick my N1 so i'm not able to mount it anymore?
__________________________________________
Update:
I sent the device into HTC' repair center, my phone had a Unlocked Bootloader.
Received the phone back today, it had the bootloader locked again and when i turned it on "Update detected" then i got Android 2.2 FRF91 YAY!
Right click on unknown device and select update driver. Then select the appropriate driver either from the SDK or the Android website. It's been discussed multiple times. Search the stickies.
Also if you bricked your phone, you'd be freaking out alot more.
I did -.- I have installed this driver alot of times, and as i wrote, i already tried the x64 driver.
Windows tells me the best suitable driver is installed, which is Unknown device.
I even tried removing all usb drivers to let it search again, i tried adding the driver manually, also failed.
I tried the driver from the SDK and using search/google i was able to find a x64 usb driver, which also fails. Windows error code 43.

Believe me, i am freaked out :/
I have been developing a android app on my laptop for about 2-3 weeks now, and i wanted to mount my phone at my stationary pc.. Now i cannot mount it on either my laptop (with all the drivers installed) or on my stationary pc :/
Here you can see what it looks like
Note: It does not accept any of the drivers posted in the USB Driver topic

Nope... I just installed Windows 7 32-bit, the same issue.
All i get when i try the drivers are:
"Windows has determined the driver software for your device is up to date.
Unknown device."
You may want to try a live thumbdrive with ubuntu 10. That worked for my 64bit system. Also you can boot your phone right?
Bricked generally means that you can not turn on your phone, thus turning it into a useless brick. From what I understand this only happens when you update the radio and remove the battery.
If you have changed your rom previously are you running the Desire rom?
I've been running the Cyanogenmod ROM while ive been developing my android apps.
I have been unable to mount it after i installed my new hardware. I should also say that my comp managed to destroy a USB-stick aswell.
Worked before upgrading comp, now it doesn't.
And yes, i am able to boot up the Nexus
If you can boot into your phone its not 'bricked'. Do you have SD card reader on your laptop or desktop, or another smart phone or device with an Micro SD card slot. If so I'd pop up the SD card and try to read it by itself. If that doesn't work I think its just the card not the phone. If it does then something screwy my have happened to your phone.

My computer also burned out my Cardreader, so that is not a option either.
However i was able to use the MicroSD reader in my laptop.
My SD card works just fine there.
Search for usbdeview, download it , run it and uninstall your htc usb drivers and then reinstall your X64 driver from the sdk. That should solve your problem.
I know this sounds stupid, but are you using a cable to extend the length of your usb? If so, unplug it.. i had the same problems, it was a stupid cable and i was freaking out.
Re: N1 Brick
No, not that either. Also tried formating the SD card, no luck.

It took me a few goes to get Windows to LOAD the correct Driver
Tried, didn't work aswell... However i do have another question for you guys:
My teacher got a HTC Desire, i asked him to try my MicroUSB (original) cable and see if he could mount with it, he couldn't either, only charging like it does on my Nexus.
So i decided to buy another original HTC MicroUSB cable but i had to wait for the shop to receive the cable from HTC.
Meanwhile i bought this cable and tried it with no luck aswell: http://www.av-cables.dk/computer_ka...a_microb/usba_han_microb_han_1_m_1888_da.html - This one didn't work either.
New question:
Does it require a original Nexus One (HTC) MicroSD cable to mount?
I mean, the cable must be broken somehow too since the Desire cant mount using it aswell.
The shop received the cable today and i should pick it up today.

This tells to me you did it wrong. Do not search for drivers, do not let let windows determine anything. Tell it you have disk, navigate to your drivers and install them. Give windows a choice and you'll never get anything done.

Windows was unable to detect my TyTn II

Windows was unable to detect my TyTn II.

I already have Windows Mobile Device Center installed (I was using it for Xperia X1)
I tried 3 different usb cables but still the same.. I have read several threads concerning about this but still no luck.
"Enable Advance network functionality" was already disabled.
If I connect my device to usb cable .. it just charge the battery but fails on detecting my device.
Hoping for advice.

My Windows7 Administrator account is enabled and that what I usually use. I have also tried uninstalling and installing WMDC but still no luck. Anyway, I have a thought that maybe, the problem is not in my OS, but the device's hardware it self...
what you are sure that all the errors were caused by the device you ...?
Hi, you should find and use update for mobile device center on WIN7

[Q] Galaxy Tab Issue

Not sure when it began but I am unable to connect my tab to any pc. I have tried 4 different ones. It just gives me the error message "usb device not recognized". I have the custom rom from overcome(the latest one) installed. I put the tab in download mode and the same issue remains. I turned on/off usb debugging and it still doesnt work. I even tried the *#7284#. That did not help either. Please help.

Have you go to samsung webpage and download the kies?

Do that first, after install it, go to >>Tools>>Install driver. Click it.
make sure your tab is connected to your PC via USB.
After you click the install driver, kies will download the driver for you and it will automatically detect your USB tab.
please try.

Sounds like a fault with windows. Try running updates or use a registry cleaner/fixer see if that helps.
CCleaner has one.
[EDIT] Ah I misread, looks like you have tried other systems with same issue. Not sure then.
I'm assuming you're not using the same cable with all of them, otherwise you'd want to try a different cable. If you've tried the different cables between the different devices and still the same issue, you might roll one of them back to stock and see if that fixes the issue or not. It's possible you have bad usb ports, but more than likely it's a software issue on the tab.

How about the usb cable? Possibility is high due to cable itself. Since you using the same cable with all PC. You should try to change it.
Sent from my GT-P1000 using XDA App
Bad cable or bad tab. Borrow a cable to eliminate that.
Not sure, When i was reading instruction for how to update with overcome rom it said that if Odin doesnt recognise the tab try a different USB port.

And same as mgregor, don't use front panel to connect USB.
Used drivers must be obsolete. Use 3.2.1 or 3.5 and be sure android platform modem is activated to be recognized by b2c
Try LG United Mobile Driver, there is a link on knzo's CWM recovery thread. And yes try a direct port on motherboard behind your cpu case.
Also try another usb cable.

Any advice?
Hi guys,
I finally managed to connect my phone to my pc. The problem was about the cables that I tried. Another original lg cable solved my problem.
But now I have an other problem. The brightness of my screen. It is usually at the minimum brightness and I can't change it. It does not change anything when I change the brightness settings. I tried other firmwares from http://luivit.altervista.org/firmwareP970/index.php but did not work still the same!
Help please...

[Q] Rooting w/o USB connection

Hi, guys! I have a really big problem :/. Right now I'm using the stock 2.3.4 gingerbread from LG ,but you all know that this is the worst OS ever. I wanted to get rid of it but i cant connect my device to the computer. It's only charging. I need a way to root it w/o usb connection. Do u have any suggestions? It's not a software problem! Something inside the phone is broken and i don't know what it is. Is there a way to root it via bluetooth or SD card? I didn't find any apps to root it too. I know gingerbreak etc, but they dont work for 2.3.4. Thank you in advance and i hope there is a solution. :fingers-crossed:
I am afraid you can't. Replacing your micro usb port could solve your problem. I reccomend to buy a micro usb port which is already on the flexible cable so you can avoid ironing.

i forgot how the mass storage settings in gingerbread look like but there should be an option to put the phone in "charge only" mode (which you should disable)... pressing menu key in settings > storage doesn't give you any options to choose?
In gingerbread you can only turn usb mass storage and usb debugging on/off. These settings didn't help. I'll read more about the first link you gave me and try it out.

This is quite challenge, root without usb connection. First idea I got to use ADB over WiFi, but this is available from ICS, not on GB.
Second idea - what I remember, some of root methods use APK installation over ADB by script. Maybe you can search for these script methods and place all required files on SD Card. Then try to execute commands by terminal on device itself to install and root.
It's just my idea, maybe wrong, maybe help.

if you read the 1st post, you might find out how could it help you... especially if you use win 8 which caused problems for many other users when trying to install the drivers or trying to flash the phone...
I - Install APX (NVFlash Recovery) Drivers if not already installed.
It starts the windows device driver wizard to help you install the drivers needed for NVFlash. It detects your system OS and gives additional on-screen instructions needed if your PC is running Windows 8.
FYI: The drivers are located under ToolKitFiles\nvflash\driver folder.

I use windows 8 from a week. Anything i've done before was on a xp/ win 7. The problem isnt in the win 8 i use now. I've tried everything on my xp laptop. I have a friend who has the same phone and he can connect it to his computer so everything is fine with his computer. I've tried to connect my optimus to his computer and again it wasnt found by the computer. The problem must be in my device.
