Hi there! First try this:
1. Change USB Cable
2. Change USB Port!
3. Open device manager
4. Look on port tab ... If it have that + click on it...
5. Now and only now plug the phone Powered ON.
6. on this step you should see Lenovo ADB Device/ Lenovo Composite ADB Device
7. This means that your drivers are installed correctly.
8. If you want to flash firmware you need to install another tipe of drivers!

Hei Stympy,
i´ve tried it step by step but there came no notification that there´s a new ADB Device (
any other Ideas?? Maybe it is a USB Port problem of my phone?

have you tried to install pc companion thru Sony Ericsson web site? do that first, it will install needed usb drivers for our phone.
@ necrohades: thanks for your suggest but unlucky i tried. "No phone conected". Is the hardware broken ?
Since you already tried 3 pc. Why not try to change your USB cable then?
i tried e71's usb cable but PC still not recognized.
Might be you need to use generic ADB driver for your phone. USB device not recognized means:
1. USB port is not strongly powered (the front panel USB usually aren't strong in current). Try rear panel USB.
2. ADB (or to be more exact, SE driver for phone) is not installed. Try install generic ADB from Google Android SDK page.

Phone not recognized by pc
I am running Cm7.2.0 RC3

I use this driver on my windows 7 pc (LGAndroidDriver_Ver_1.0_All) downloaded from Microsoft
I can,t remember exactly why but the I had to uninstall the driver supplied with the LG mobile update tool as it interfered what i was doing at the time.
I have to have debugging on and connect the cable to the PC first then the phone

I Hope this Helps! I have attached the driver press thanks if It helps and post the outcome, I will try to help as much as possible.

[GUIDE][CM9][HOW TO ESTABLISH - USB Mass Storage]
Since you've stated that the problem exists irrespective of the ROM you use, there is a possibility that your microUSB port of your phone might be damaged.
Also try and install the drivers on a different computer and see whether it's working or not. Also, if you can, borrow another LG P500, connect it to your system, and see whether it is working as it should. This will help in identifying where the problem actually is.
Hope this helps.
If their aint earthing in the socket u plug ur pc then congrats ur pcb of the phone has been damaged
get it replaced via lg service center

happened wid me too once

i5500 does not connect to PC.

Hello everybody,
I have a problem with my Samsung i5500. Every time i try to connect it to a PC it is not detected as a mass memory device and gos straight into charging mode just like i would connect the phone to the socket charger. The PC does not recognize the phone, it doesn't do anything, just like i never connected the phone through the USB port, but the phone is charging.
I tried to connect the phone on 3 different computers using 3 different micro-usb cables. On all 3 computers I installed the latest drivers for the i5500 and the same problem occurs every time.
Can anyone please help me with an advice. What should I do in order to get my phone connected and recognized by the PC?
In case you it helps you to know, I am using the stock 2.2 ROM and the phone is not rooted.
Thank you in advance.
i have EXACTLY the same problem, and it is not drivers problem. Any advice?
hey guys, This is the link to download for drivers.
http://d-h.st/iPk
If you use windows 8 or 8.1 then you will have to extract the file you download from the link above and then right click on the .exe file and go to 'properties', in that go to 'compatibility' and in that choose your operating system as "WINDOWS 7" and check the option below 'always run as administrator' and there you go. Double click on .exe file and follow steps. Install drivers. No need to restart the pc also. (if your phone also do not detect after installing these drivers only then restart).
Can you just try this out? I know it is maybe not driver problem but still you can try this.

[Q] THL W100 and problems with Mediatek USB preloader ....

Hi all...
I received my THL W100 yesterday from an italian reseller... I ordered it already rooted and it arrived directly fron Hong Kong with the latest firmware 130711 and prerooted with Superuser (I checked it with root checker and it's effectively rooted...).
It also has it's own recovery pre installed (when I enter the recovery mode with pover+volume up it appears an "android recovery"...)...
I wanted to flash a different recovery (the Barry63 recovery) and so proceeded with installing in one of my four pc (running win XP SP3) the drivers I founf inside the Ro.edi package... after this, I turned off my phone, disassembled the battery, put the usb cable both on my phone and on my pc and finally inserted the battery... I hear the tipical sound played when you put a new USB device in a computer and immediately after (a secondo or so...) a second sound tipical of when you disconnect your USB device... all in all my phone automatically disconnects and this results in a "non installation" of the Mediatek USB preloader I neeed to use the SPFlashtool...
I tried on anoter pc of mines, running Win XP (a modded version) and got the same result...
I also tried another pc running Win7 Home Premium , forced the installation of the Mediatek USB preloader via the "hdwwiz" method, put the usb cable in both the phone and the pc, re-connected the battery and... it recognizes the new device, starts to install the Mediatek USB preloader, but after some seconds it says "device diconnected"....
Same issue on the fourth and last pc of mine running Win 7 starter...
It's like my phone has something in the firmware (root?Recovery?) that doesn't allow me to install the Mediatek USB preloader...
Any idea about it ?
My phone works perfectly, the pc recognizes it both as USB archive and USB debug... I can do almost all the things I want (the phone is rooted and so I installed all the apks I wanted, included the MobileUncleTools... but I can not use the SPFlash tool as I can not install the MediaTek USB preloader... :crying:
Thank you in advance for you precious answers...

Yes... it was enabled...
Anyway I solved the problem... I discovered that what it happened to my phone is the "supposed to be" for that driver... in fact, after launching SPFlashtool and press dowload, when you plug in the battery on the phone SPFlash recognize the phone and starts flashing the right way.
Finally I succeeded in it and flashed the Barry6030 recovery. :laugh:
Thank you :good:
