unknown device xPeria x8, Help!

Hello.
I have an xperia x8 with Android 2.1, the original factory.
What happens is that some time ago I bought a USB cable and plugged it into the PC almost always selected the option to "load", but now I want to connect me to root does not show anything. Absolutely NOTHING!. On the computer goes "unknown device".
I've tried, downloading drivers, uninstalling and installing drivers again, changing the USB cable, connecting to a laptop, restarting my phone to the factory data. Which makes me think the problem is with the phone, I tried to Flash but can not for that that the computer has to recognize the phone and as I said, does not recognize my phone.
I wonder if you can fix my phone or can root without connecting via USB.
I have to mention that I have a memory reader on my computer, so all my files, music, etc. .. always happened to my PC using the memory reader.
I hope to have a solution for weeks trying to come thousands of methods and not one for me. ):
Thanks in advance.!

As I said, and tried it on my brother's laptop.
What might be, if your version is correct, the cell would not connect to W7 64bit OS. I'll try on a WXP, but as I said, I wonder if you can root without USB cable.
Thanks in advance!

[Q] Kies on PC does not work via USB?

Hi,
I can't connect my Note to Kies using USB.
Tried installing the drivers again, Different ports. It works via Wifi but not USB?
Also tried switching from MTP to USB storage mode and back but it's not working?
Anyone got any idea's
Oh I've tried different cables as well
Thanks

Hi,
Try to manually update your USB drivers (in the Windows Hardware Divice Manager)
When you open it you'll either see a device with a question mark or find the Samsung under USB devices.
Hope this helps,
Ton

Try a reboot of pc after doing connection troubleshooting through Kies, als disconnect and reconnect phone to pc and pass lockscreen on phone
Which rom are you on?

newbie to GT-i9000M - can't connect to Kies

Hi to everybody!
I got used i9000M (Canadian) for my daughter (I have LG 3D so not really newbie to Android). It's in factory default state with 2.2 Android.
I tried to update system using Kies but have problem connecting my phone to PC. If I just boot phone up my Win 7 can see it (but not kies). I enable USB debug and Kies says something like "mode is not compatable". Should I untick USB debug and enabler KIES mode under Wireless?
But once I unplug it and plug back I get error 43:
Windows has stopped this device because it has reported problems. (Code 43)
I read and read and read... I'm ready to try odin but I don't know what exact ROM fits my SG... Also lots of stuff is connected to megaupload...
Thanks for any links in advance!

There is an option on Kies to reinstall drivers. I would suggest trying that. But above all, I would advise on rooting the phone and installing a custom ICS rom, like SlimICS. It will add tons of features and make your phone faster while conserving battery life. If you want to transfer files, just plug your phone in, and enable USB Mass Storage mode and you can just drag and drop files like you do with normal flash drives.

If you want to fix code 43, you should try http://forum.xda-developers.com/showpost.php?p=27205737&postcount=4571
IF you want to upgrade it by Odin , the Latest Gingerbread ROMS are here http://forum.xda-developers.com/showthread.php?t=1102881 ,choose the one for your region, all other resources that you may need can also be found at the My Android Collection link below

Thanks for reply! But here is the strange thing :
If I set USB debugging mode on the phone, my PC sees it with no problem and I see two devices in Device Manager under Portable (and they are identified as Samsung ...) But in this mode Kies doesn't connect - I get message like "unable to connect, switch phone to Kies mode ".
But once I turn debugging off, turn Kies mode on and connect the phone, my PC sees only one device and it's in USB group (in Device Manager). And now I get error 43...
So I think it's not the physical connector (otherwise I would not be able to connect at all) but rather old system - 2.2
I'll try to update it with Odin and let you guys know the result.

You should instal SAMSUNG USB Drivers for Mobile Phones from here
Also try different usb port or computer. Make sure to kill all Kies processes when you using Odin.

Thanks for help - still no luck
Guys, thanks for help! I really appreciate it!
I installed SlimICS - phone running nice. But my both computers (XP and Win7) give me errors...
Funny part is - Odin works perfectly and I can see my phone in Device Manager with no problem!
Anyway, it's not REALLY big problem, rather inconvenience.
I don't know if it matters, but I also noticed that my AC charger for LG doesn't charge i9000. Weird? Do they have different pinout?
Thanks again.

It's me again
Just for fun connected the phone to old Toshiba laptop at work with win XP, without installing any Samsung drivers and ... And Toshiba recognized phone and showed me two drives - internal and SD!!!
My home computers still giving me grief... Both systems (xp and wib7) stubbornly don't want to install drivers! They put some Microsoft driver from 2007...
I'll keep fighting (installed Kies several times, just drivers - couple versions...)

connexion usb don't work but "mtp connected"

Hello everyone,
Here the problem, I just acquired a Galaxy note and I can not connect to my Windows 8 PC (or windows 7) . Whether with or without kies.
In the device manager I have "unknown device"
I also tried odin mode and recovery of origin, but no way to install the drivers.
The galaxy shows in the bar notif "mtp connected" ( the smartphone is charging)
It is version 2.3.6. stock not root with kernel: [email protected]#2
did someone have an idea?
thank you in advance for your help.
Sorry for my english, i'm french.

U can set it in Settings > USB
But since u are using GingerBread, ur device might not be able to detect the usb port as more than charging port. This is very unlikely but it can happen..
And do Enable USB Debugging..

i have tried but it doesn't work too

uninstall kies and drivers reboot the pc. then download
http://developer.samsung.com/android/tools-sdks/Samsung-Andorid-USB-Driver-for-Windows
and install it without the phone connected. connect the phone and see what happens.. when you connect the phone, there will be notification of drivers being installed in the system tray of pc. click on it and you will see what is installed and what is failing.

Change ur usb cable to another usb port. This happened to me last time when I tried to flash new rom via odin. Everything is fine but the odin didn't detected it. b4 do that remember to install ur GN driver.

i have tried to reinstall drivers but always the same problem "windows can't install the device...)
i have tried use 3 diferents usb cable too... no result
I would like change the rom (to see if it was the probleme) but it's impossible without root. And the phone don't propose upgrade OTA...

There could be a problem with the usb port itself. You could try to clean it and test again.

i have do this but no result...

Then it could be your mini USB cable. Try another cable.
Edit: Sorry, accidentally misread something. You tried 3 usb cables. My bad.

[Q] Problem with connecting LG P970 to PC

Hello people
I'm new here, in terms of asking questions and seeking help
I have the LG Optimus P970
A few days ago I made ​​the update to ICS, and by proceeding with this page, hackmyandroid.com/optimus-black-p970-official-ics-update/3299
After that, not impossible to connect the phone to a PC, even the software update mode, it can not recognize, anyway to connect it just throws a slow charging.
Is there someone who knows what it is.
I'd love to go back to the old software, but there is no way to detect it pc
Sorry for my bad english
Thanks in advance

I forgot to say, before the update, and my computer still recognize the phone, connecting it over sony usb cable, now it is no longer recognized by the Sony USB cable, and I do not have original LG USB cable.
Perhaps this is the reason why a computer will not recognize the phone

I have the original cable, but still the same problem.
I have all drivers installed, I can transfer files between the phone and the pc, I can use the LG suite,
But I can't see my phone on the ADB console, I can't use smartflashtool cause the phone isn't recoginized.

yesterday I tried with lg cable, and wall charger, in both cases, said slow charging the battery, I tried on three different computers, I tried to reinstall the drivers, like the software blocked communication with the phone, just charge the battery.
If there was a way to put the software through SD card, it might solve the problem.
even the software update mode, the computer does not see the phone

Bro! For the softwaretool like smartflash, You need to boot into download mode i.e., You need to switch off the phone, plug in the USB cable connected to the PC and instantly press the volume up button. Then the tool will recognise Your phone. Try it and check once!

I tried it, nothing happens,
I go to download mode, but computer does not recognize it again
behaves as if the port is destroyed

Try to boot your PC with disabled driver signatures, or use a 32bit windows system.
try entering download-mode the following way:
disconnect your phone from pc
remove battery
press and hold Vol-up
connect the usb-cable (still without battery)
Now the phone should be detected as a serial-cable device an you can use the smart flash tool.

would have to be sound,
no sound when I connect the phone to the PC

Solved my problem.
Seems like windows automatically installs driver to the phone, but it partially works.
Unistall all drivers for the phone, or try on a new computer.
Plug the phone and cancel the driver search by windows
Install drivers for LG (unplug the phone before)
Turn it off
Plug the cable and enter download mode
And there is the phone recognized on smartflashtool.
I'm flashing a new one right now, thank you.

You do not understand the problem
there's no sign, no sound when I connect the phone to a computer, any computer, drivers were or were not.
As if something in the phone blocked communication between the PC and phone

Connection Problem with Mackay 2.999
Hey Guys,
first of all, sorry for my not so good English
I'am at Mackay 2.999 with last Kernel of his build and can't connect the Phone to the Computer.
It only install the LGE Mobile Composite USB Device, the LGE Mobile USB Serial Port and the LGE Mobile USB Modem on connecting to the Workstation.
I had test it on many Computers but the Problem is all the same: I can't get on my Memory or ADB.
I also had testet all modes under the setting point (MTP/PTP/mass storage device) and with debbuging on and off.
On my Workstation is the Last Version of ADB (1.0.31) installed.
Did anyone know the problem?

Did no one know a result to this problem

Hmmm my PC also can't read my storage what I did is go to cwm and plugged in usb cable and pressed mount storage it seems to solve my problem. I also did a cache and dalvik cache wipe.

Hey, I have found the result to this problem. You must flash another Baseband. Use from Nooby the V30 Baseband and it is solved.
