try to plug in another usb port!! witch SO do you have??

Looks like a driver problem to me. Uninstall the previous driver if you can, if not no problem. It updates on previous version. But make sure you install the right driver. This is the driver:

Solve the problem, I do not know how, reinstall drivers several times, restart and solution, my problem was with version 2.2.2 and I updated to 2.3.4 from page LG, thanks for your help, greetings

thnx guys, have A GOOD TIME
PD: i have a LG optimus black with GB 2.3.4
you didn't describe your issues, but I guess they're related to processes.
backup, do a factory reset. If problem persists, reflash.
OK let me try this,... And I'm sorry, yes its the process...

Problem with USB since 6 months ago!!

Hi guys!!
Look at me, i have a problem with mi galaxy ace v.2.3.6
When i connect the USB cable in my computer, the phone don´t show nothing!! It´s not detected.
I tried with Kies, depuration...
Some solution?
Thx, m8 and sorry for my english
Ok there are a few things i suggest you try/check:
Do you have the correct drivers installed on your desktop?
If not these need to be installed.
Is Usb debugging enabled on your device?
This option can be found in your settings.
Is your usb cable damaged or old?
Try a differt cable.
Hope this helps

Reinstall Kies and if on a custom rom, then change ur rom
The galaxy should show anything about the conexion with my computer?
Don't show any notification when i plug the cable

Yes, show a notification "USB Plugged"
..silly question;
Why do you want to connect it to the computer?
Backup rom, manage roms...? >>> CWM recovery
Tranfering data, files...? >>> wifi tethering, ftp servers, Mi File Explorer, e.g. ... You should see my toturial xD

[Q] USB drivers?

Is there a download for the latest drivers somewhere? I tried searching, but I'm probably doing something wrong. I have a version of the USB drivers installed, but it's at least a couple years old by now, and my new S5 Mini isn't recognized.
Install latest version of Kies in your PC and drivers will be installed

But I don't want all of Kies, just the USB drivers. Sorry, I should have been clearer in the first post.
If you install Kies the USB drivers will be installed. Then you can uninstall Kies because the drivers still will remain in your PC.
I hope this will help you.

Hard Brincked MI5 at first day of use !!

Hi,
I bought a Xiaomi mi5 recently, it arrived with a vendor version of miui 7.3.x.x. Since didn't want to install any custom rom, I didn't unlock the bootloader. I tried to install the global miui 8, directly from updater app, as I have done with other xiaomi phones, but didn't work, (Can´t verify update)
So, for locked BL just entry in EDL Mode by adb it works, I´ve flashed the last MIUI8 6.11.10 and all ok, nesxt day , first day of use,
thee device freeze the screen and i did a force power off, after that ... dead
At the moment, the phone doesn't boot normal and doesn't boot into recovery mode either, doesn't turn on at all. The led only blinks red when battery is too low, after charging it a bit, it stops.
But is recognized as Qualcomm qdloader 9008 by the pc, I try flash again through miflash with different official fastboot rooms versions and different miflash versions, it flash with sucess (after 2 long hours ) but the phone is still dead.
I already read really a lot of sites and forums and tried the recommend solution, but the phone is still dead. Only solution that I didn't test yet is with qpst, a tool for Qualcomm SOCs unbrick.
Any ideas?
Thank You!
Hi, any solution? Or is dead for ever? after searching day by day can't find a solution!

Try to flash with new mi pc suite chinese version, new pc suite chinese version can automatic detect and auto flash, you just plug your device and mi pc suite give option to flash, edl mode or fastboot, select your type your device and browse whre you put rom, fastboot rom with *tgz extension, wait till success, i'm success with this way..good luck
Hi, but from what I know PC Suite only works in fastboot mode does not work in EDL mode, I already tried this option it does not recognize the MI5 in EDL mode.
Can anyone please check that your mi5 is recognized by the PC suite in EDL mode? Thank you.

But was your Mi5 in the same condition as mine? That is, Bootloader blocked, no fastboot, no download mode, just even EDL all the time?
Thank you
