It all started when my phone didnt connect to the pc with my own microusb cable anymore. After lots of reinstalling drivers i tried another usb port, now the phone did connect. In a rush i started up odin to flash standard firmware so i could get my warranty for the usb failure. Then during the flash the phone lost connection again and hardbricked. I can only get it to download mode but the phone has the usb problems mentioned before again, i cant connect to odin/kies/pc. all pc's told me that the usb driver could not be installed
try removing all usb drivers with usbdeview, make sure that KIES aint running in the background, boot phone into downloadmode, connect is and as soon as you'll see the yellow com-port sign; hit start (with the proper .tar files at pda/phone/csc).
only one way to find out =/
Thanks for the help but the problem is that the yellow com-port sign wont come because the device isn't recognized.
You have download mode but no USB .
Remove existing KIES and all USB drivers reboot reinstall KIES and try .
Not work try on a different PC .
But unless you have fixed the initial error you are wasting your time .
Initial Error you said >>>It all started when my phone didnt connect to the pc with my own >>>>> microusb cable <<<<<<<<<<<<< anymore

Tried another cable and another computer, still no connection. I think probably an internal failure in the phones motherboard?
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!

Make sure the cable is properly connected. Check for dust that might prevent it going in properly. Try a different cable. What OS are you using? I found where bootloader is dmg or incomplete Windows fails to detect it. Linux on the other hand detects it. Can't use it but you can detect it.
Can you connect to SW Update Mode? Battery out and plug into PC while holding vol up button.
If nothing works try taking it into the shop.

You can root your phone from there. If you have SW Update. I recommend taking it into the shop if you are still under warranty, If you don't have warranty then you can go ahead and root. Just install a patched bin and fls with Smart Flash Tool. It's one of the stickies (How to unbrick, I think)
hi
new to Android nation
I have the same issue when connecting to USB...
And I managed to flash with custom firmware (latest ZEUS version) and I rooted but the issue with USB connection is still there...
Anyway, I wiil try connecting it to Linux to check if that would work with USB connecting
UPDATE:
OK after some digging, I managed to (at least temporally) solve the issue... After fresh installing official 2.3.4 firmware I booted to recovery and from there formatted the system folder and then installed Zeus v7 firmware... anyway, USB connection and charging indicator work fine at first booting to system... As soon as I reboot the OS USB connection (and charging) get unstable, and after third reboot it completely goes away and the device does not recognize anything: if I connect USB cable it does not show any sing (charging indicator does not show battery charging, nor the device offers me to connect in mass storage, windows recognizes only modem but not the USB storage) and when I connect charger, battery indicator does not flash as charging... Battery monitor tool shows that "battery is discharging" even though the battery capacity seems to increase (according to growing percentage of battery capacity)... Is there a some kind of USB server... I am a total noob to Androiid OS (used to be Symibian from its beggining )so I hope you won`t mind if I used wrong terms in my explanation/comment...
I hope my explanation is not confusing
Cheers
UPDATE 2:
After installing Zeus v7.01 update, battery charging recognition got fixed using both USB cable and wall charger...
Anyway, USB recognition by PC problem still exists... But when in recovery mode I can successfully mount SD card to PC in Mass storage mode...
Will keep you updated... :victory:
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.

That's weird. It could be possible that the ROM isn't receiving the correct input stimulus, i mean, it didn't know that a charger is plugged in.
Since you are a stock user, I'd suggest repairing the device using the Xperia Companion. You may search for the tool on Google. This is an official SONY software though, so keep your eyes so that you do not fall into malware traps!
This problem fixed after change mtp to ptp in menu setting > xperia > usb configuration. The usb work fine.
I think this problem is over, but after ubl, intsal twrp, instal cm 13, this problem is come back.
I was change usb configuration in developer options (in cm 13 roms) but not work again like stockrom 4.3
any suggestion ? i want using cm 13
i think my phone missing configuration / driver usb mtp or something u.u
after searching in google, many other sony device have same this issue...
can i go back to stock rom using twrp ? coz it was the only to installing rom.
my device cannot detect in pc
Oh well, i assumed that by "offline" charger, you meant charging the device while it is turned off.
If you could charge the device without any problems while using the wall charger, it could be possible that the problem lies on your PC. Please install appropriate Xperia SP drivers.
