DO NOT use flashtool with c4+c5 mediatek powered Xperia devices it hard bricks them turning them into nothing more than expensive permanent paperweights. It does clearly state this on the flashtool download page. No idea why it's only these mediatek powered Xperia devices as it works great with my xa

Download and install seus (Sony Ericsson update software) from site. Maybe you don't have drivers installed.

[Q][HELP] Xperia P won't connect with PC (Charging only)

My Xperia P just won't connect with PC, it just behaves like its on wall charger when I connect the cable,
no notification about storage mount, not even a sign of phone connected to PC. Neither on Phone or PC.
No driver install on PC, no notifications about device connected. Not a single error notification on PC. Even cant find phone in device manager.
PC companion cant find the phone, even flashtool cant find the phone, I cant get into fastboot mode too (installed flashtool drivers).
Tried every driver, cable, usb hubs, other PC, Windows 8, 7... nothing.
USB Debug is ticked in phone, PC Companion install too (still didnt start), tried hard reset too.
Its same problem as here: http://forum.xda-developers.com/showthread.php?t=1837977
Details about phone:
Xperia P
6.1.1B.1.54
Bootloader unlock possible but still cant get into fastboot so no way to do that.
Bought in Poland (T-Mobile PL branded, probably sim-locked?. But I'm using Slovak T-Mobile and it works)
Please help, I dont care about USB Storage now (I can get to it by Airdroid) but I want to root my phone and Im not able to do it beacause of this.
Try unticking "Enable USB Debugging" and then connect your phone to your PC. With PC companion installed your phone should normally be recognised by Windows.

Install XP drivers from Flashtool. Also install fastboot drivers from flashtool.
Here's the steps:
1.) Open Flashtool
2.) Open Fastbootmode in FLASHTOOL, (from the thunder icon)
3.) Connect your device in fastboot mode
THIS STEPS SHOULD BE DONE FAST
4.) After connecting your device, select Reboot into fastboot mode (via Fastboot) from the Fastboot Toolbox, (right side)
5.) Congrats, you are now in fastboot, flash any kernel you want with autoroots.

i had the same problem... when i try to connect it says no device detect. i was using go launcher but when i used the original xperia launcher and closed the go launcher.. the pc companion detected my phone.. not really sure how that worked.. but it did.. >____< it was hard to follow the technical solution in the internet.. so im glad my problem was simple as that.. just check if you had the original xperia settings.. and try to connect to pc.. hope it works for you too!

Unfortunately the port is part of the main board and cannot be replaced
I've seen at least one forum member that reported to fix his port by pulling the contacts with a needle, though I would not recommend it at least untill you have confirmed this is in fact the problem, at service or lab/store.

My Phone is connected to pc.No driver installation what is the problem?
Hello,
I have an Xperia P and since yesterday I have been having the very same Problem!
I can connect the phone via USB with my computer but the only thing it would do is: CHARGE
no data connection via usb.
I tried everything i know, like rebooting, entering fast boot mode, installing Sony Companion, enabeling / disabeling usb-debugging, deleteing old junk-data to decrease the amount of elemtents on sd-card... but nothing happens. neither windows nor ubuntu-mint will recognize my phone except from charging.
has anyone of you found a fix for the problem?
i run: nemesis kernel v.6.3 and Honami MoonWalker HD V6 (but i think its not a problem of kernel / ROM because i've been using this combination for a while now and it always worked!)

What exactly do you mean?
Do you want to know how I installed it on the phone? Then you should look for some tutorials, there are plenty.
Or do you want to know if it is actually working? I can tell you, it is, don't know why you wanna get a video or screenshot, because its actually not really realated to the thread's topic

same thing happening with my Xperia S :crying::crying:
if u find any solution plz tell me
Any news about this problem? Im facing exactly the same problem.
The phone works, but no USB connection. I cant enter in fastboot, nor flashmode, or whatever.
Tried all trick described in XDA, (rubber band, full charge, full discharge, etc...)
Factory reset doesn't help too.
update:
I have been using the phone without usb Connection ability for a while now and transferred data files via wifi-app on my computer when I needed to.
Eventually the phone died yesterday, because it is not charing anymore ;(
First it started like this:
I had the charger plugged in and it recognized it, showing the flash icon within the battery icon. But nothing actually happened, in fact, the battery kept draining.
So i tried differend chargers and cables but nothing worked. I wasnt able to prevent the phone's battery from completely depleting. Now, the phone won't turn on anymore and when I plug in the charger, the red Status LED will turn on for about 5 minutes, then it turns off again and nothing happens. I can repeat that but i figure, the battery is not getting any energy from the charger
Does anyone know how to fix this, yet?
The phone is slightly over 2 years old...

To go to flashmode on flashtool you need to put the firmware on the correct folder. Where have you placed the ftf file?
Do you have unlocked bootloader?
If not, then fastboot is not for you and have option to use Pc Companion to repair your software if the problem is in there.
Did you install flashmod drivers for your phone?
What happen if you connect your phone switched off with hold down the button volume - and connect in the same time usb cabel to the phone?
Did you see green light?

i didnt put it in a specific folder, at the moment its in the download folder.
but the ftf file is loading perfectly, the problem is when it says to connect the phn and doesnt detect it .
i connected the usb holding the vol down button and the red led turned into green, but the pc starts showing usb device not recognised.

no bootloader is locked.
it had the original stock firmware without any modification(not even rooted) before it went dead.
the same thing happens with pc companion it doesnt detect the phn.
and yes the green light turns on.
Like i say before. Don't wait Pc companion to recognise your phone.
Just turn off the phone, charge it good, after that connect with Companion WITHOUT turn on the phone or what you want and continue with the steps.
Doesnt flash mode work even with a locked bootloader?
Maybe you haven't installed USB drivers. Go to local disk C then flash tool and then open drivers and install the drivers for your device.
And then check flash boot again.

Flashmod is for device with locked bootloader and flash on stock files.
Fastboot is for device with unlocked bootloader and for flash on custom / different from stock files.
Fastboot will not do the work after the author has locked buuloader.
Better use Flashtool with flashmode or Sony Pc Companion or Xperia Comapnion, again with flashmod / green light.

and thats why fastboot drivers are working fine.
It is normal to not recognize the phone after not loaded operating system.
In the video I will share, will also see that there are unknown devices, but this is the menu models to indicate the program right model and proceed to download and install the software.
Just try it, if i understand you.

Do you have unlocked BL? Have you tried to fix it using pc companion or not?
EDIT There is something called Newflasher. I have used it few times but I don't know if it works with locked bootloader and disabled developer mode because I have a TA backup and unlocked BL. You have to ask on this thread https://forum.xda-developers.com/cr...gress-newflasher-xperia-command-line-t3619426 and try to do it by yourself. It may get work.

Appreciate your suggestion. I tried PC companion but it can't detect my phone. I've never tried to unlocked BL.
I'll tried with Newflasher as you said.
EDIT: The newflasher can't help. I think the main problem for my phone is that all buttons are not functioning. May be I accidentally did something in developer mode of my phone before it got crashed. (when i connect to charger, screen shows Xperia logo , then a triangular repair sign and finally a green charging battery).

It is hard to diagnose through the internet but we can try to eliminate next causes. So, you can't flash due to turned off USB Debugging or because you cannot enter flash mode? It is important because if you have hardware issue with buttons fixing it may be a solution. I have disassembled my XZ1 and I know that buttons replacement is quite easy for people with some experience and they cost about 5-10$ or 4.5-9.5 euro depending on region. Have you tried safe mode? The most important is that your phone is not dead at all, so there still is a hope.
