[Q] Dead USB Port (No Charging, No connection to PC) - Xperia Z Q&A, Help & Troubleshooting

Hello Guys!
I bought a used Xperia and I had a lot of fun with this great phone during the last few days - but after sending some files via USB (using the Sony Software) to my device I got a error message, unplugged the smartphone and since then the USB port isn't working. I can't charge my phone and I can't connect it to my neither to my PC or MacBook. I also tried a few different cables.
Is there any chance to fix this problem?

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:

my xperia t dead need help!T_T

hi! i've bought my xperia t today
it goes well! i've connect it to my pc, and pc companion find an update and ask me if i want to update my phone
i said yes, and it tried to install the upgrade, but about the 75% it gives me an error
and from this moment the screen of my phone turns on and off every 5seconds
with a black screen with the white sony's logo and the pc doesn't recognize him and no led turns on
after about 2hours the phone turns totaly off
i've tried to turn on with the power button and the volume down hold
and the red led flashes for 3 times
if i hold down the buttons while connecting to the usb or to the charger,
the red light stays on and after about 15min it turns in to green and a black screen with sony's logo appears for about 20 minutes
but no leds are on and if i plug it to the pc or to the charger nothing happens
sometimes if i hold down the 2 buttons when i plug it to the pc the led turns on green and the SUS recognize it
and tries to upgrade system but after a few minutes the phone seems to turn off and the upgrade fails
what i have to do? probably the phone needs to be charged before being upgraded
but if i plug it (at the pc or even at the charger) with the 2 buttons holded down the red led turns on but after 15min it turns green and the sony screen appears and freeze
if i plug it without holding down the buttons no leds turns on and i'm not sure if it's really charging or not...
any sugestion? thanks

But why did you try to upgrade a phone out of the box?
Oh well... My suggestion is to take it back to the shop. Tell them you bought it, connected to PC, followed the prompts to install PCCompanion and then it faulted.
Soon, we will get stock .ftf's posted here that you will be able to flash in flashtool, but that sounds like a bad phone. If the fault was staright from the box, take it back.

OK, but if there is a problem with the phone, no amount of flashing will repair a bad board or a bad chip....
I will post a stock vodafone UK .ftf here this weekend, then you should be able to flash that (Using flashtool, first post in the dev section) to repair your phone. But i do advise that if your phone id faulty from the box, its a hardware issue not software..

You need to turn on usb debugging. It's under settings/developer options. Should work after that. Good luck!
obviusly i can't turn in debug mode as the phone don't turns on!
after a night plugged to the charger (no leds on)
today the phone don't do nothing...
no flashing red led when i press any button or any sequence
only turn the red led when i hold down the 2 buttons and plug the usb or the charger
but when i release them all turns off....
Have you tried a factory reset? You should be able to do it via Android stock recovery and that might rollback the corrupt upgrade.
Worth a try.
first i need to discover what you're talking about...

I will describe what programs showing because i have polish version and maybe you can't understand them:
When i'm trying to connect to pc companion when pc recognise phone i'm geting message PC companion could not connect with device disconnect device and try again
When trying do sof/hard reset nothing happens
When trying to pull in fastboot or flash mode pc recognise phone always the same in conrtol panel ZEUS FLASH device pc also recognise in thisa mode without battery and without pushing any buttons but i'm not geting any led Green or blue only when i'm conecting charger or usb cable WITHOUT battery it blinks red ones
When i'm trying to flash with flashtool or original update service when program is on screen asking me to connect the device i plug usb pc recognising the phone (usb connected device sound) but program doesn't start to flash or even recognise
i have also setool when i'm trying to flash by setool when program is waiting for device connecting bar is moving on down side of window when i connect the phone it is stoping like it tries to connect but nothing happens....
i was thinking to try this but i have cheked battery voltage and it is 3,88 so i thing it is fully charged:
Here are the steps I took successfully revise my phone from soft brick.
Let the phone charge (long long time = 4+ hrs) on wall charger.
Red light on (constantly - not flashing) - charge until red light off (again very long time =16+ hrs)
Unplug from wall
Run flashtool from PC and run flash .111 until it asks to put phone in flashmode
While hold volumn down and plug in USB
Red light will be back on, after a few seconds - flash will run.
Unplug USB then power on - phone will boot and die (it's okay don't worry)
Charge the phone again - after a while (or let it charge full), you can now turn on the phone.
That is all ... Back and running.
GOOD Luck.
Timing = could be different from phone to phone - depends on battery of the phone before it dead.
please do you have any idea? for me it hangs in some kind of boot mode and i don't know how to kick it fromthis and reflash if any screens can help please tell me i will do them

OK,
Yes thats true but it sounds similar to a problem I have come across before. But this happened when someone flashed the S1 update on the TX instead of the T.
Have you unistalled evrything android/sdk/adb related from your computer and started again.
Also, you can try another machine.
Are you on win8? That has issues with drivers from Sony.

I dont know where testpoint is on xperia T as we have never been down that road here.
Has he tried to use EMMA to flash something? That is meant only for unlocked bootloaders, maybe he has messed up with that, but I am onl guessing here and i cant really see why that would do anything to the boot...
Maybe he tried to flash it, dropped it, broke it, and thinks a software hack can help him....

[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.

Cant connect to PC and access my data

Hey guys,
long story short: I flashed my device and now my pc wont recognise the usb-connection between my phone and computer. The hardware-manager describes as if the phone cant tell the computer that it is a z3 compact.
Errormessage: Unknown USB-device (Cannot get the device description)
*something like that*
what I did to troubleshoot:
- reflash the device with firmeware: A.1.264 (without this strange script)
- reflash the device with the concept preview (without this strange script)
- installed PC Companion from Sony
- Linux cant see the phone, but can flash it
- USB-Debugging wont work as well
Nothing worked for me so far. Anyone an idea what to do?
thanks in advance

Some roms come with the usb functions disabled, removed as bloatware. So it's possible the first rom you tried didn't have the usb functions installed.
Do you have the correct drivers
Presumably flashtool can see your phone and it's still charging, so I'm sure the hardware is ok.
Did you try a repair with PC companion?
Do you have a different usb lead you can try?

Hey,
thanks for your answere. I found a "solution" to connect the phone via fastboot to the pc and with this I could do a complete reset with the PCC. When the phone is booted however I get the same error message over and over again: Cant get a device description!
Maybe you can look up the specific driver which is used in the device-manager so I can force windows to use this one?

Did you install the ADB drivers that come with flashtool? Look in the install folder for a folder called 'drivers' run the exe in there and tik the fist two and then Z3c.
Yep, all three unsigned drivers.
