Unable to start in FASTBOOT

Hi,
On my previous PC windows vista(who died), I was able to Root my Xperia S and all was ok.
Now I'm on a windows 7 64 bits, my Xperia S is recognized:
But, I'm unable to start on FASTBOOT my phone :
phone OFF, connecting USB + Volume/+ --> blue led for few seconds then Doom Kernel Logo, then green led and green battery.
I probably miss something, but what?
The drivers are missing,did you install pc companion??
Check the dev section on how to.....

yes, I installed PC companion, and my phone is recognised by PC companion.
I tried :
power down ur phone and keeping the Volume Up button pressed connect the USB cable to PC this will trigger FASTBOOT mode and windows will start driver installation, extract the above package and point the driver install to that location (usb_driver) folder
but I'm never asked for driver installation...

You can find here fastboot package and drivers.
Sometimes when you connect the phone in fastboot mode,widows will try to install the drivers automatically so leave it till you get an error then unplug and plug again in fastboot mode.

thanks for your time,
I tried :
"
-download the fastboot package with usb drivers (alternate drivers if the ones in package dont work)
-make sure u have a windows PC with USB cable to connect the phone
power down ur phone and keeping the Volume Up button pressed connect the USB cable to PC this will trigger FASTBOOT mode and windows will start driver installation, extract the above package and point the driver install to that location (usb_driver) folder"
but the point is that i have alwys :
phone OFF, connecting USB + Volume/+ --> blue led for few seconds then Doom Kernel Logo, then green led and green battery.
and never stabilise in Fastboot mode.
I tried 50 times.
Delete the S1boot fastboot from device manager ,reboot the pc and try another usb port and maybe disable antivirus if you have one.

[Q] Xperia U Fastboot mode

Hello, I can not enter fastboot (or flashboot) mode on Xperia U, I want to unlock bootloader, I got unlock code from sonymobile website, I am following instructions , but I can not get in fastbot mode anyway,
When I turn of the phone, and press volume up and power button simultaneously while plugging phone to laptop, in device manager new unknown fastboot device apair, but for few seconds, I can ot install android_winusb.inf either, it says, that windows could not find any drivers.
Anyway, after few seconds unknown device disrepair and phone goes to charging.
Android version 2.3.7
windows version win7 ultimate sp1 64 bit (may be this is the problem?)
http://forum.xda-developers.com/sho...sible+solution+for+fastboot-windows7+problems
I Installed flashtool and flashtool drivers for it and finally entered in fastboot mode
Problem is solved
Funny thing is, that it still not works with Sony's original micro USB cable, but works perfectly with Samsung's cable
Windows treats every USB port independently. So windows has to "install" the driver again for every new USB port used. If you connect the Sony USB cable to the port the Samsung is currently connected to it should also work for the Sony cable.

[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!

You should choose "Let me pick a list of device drivers from my computer" and find your phone driver that you installed before.

The port is where you plug the USB cable into. It's probably damaged.

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...

Xperia Neo MT15i USB Flashmode not recognized

Here's the whole story, I tried to root my Xperia Neo using the Eroot application that I found on this thread http://forum.xda-developers.com/showthread.php?t=2220568 , I tried a couple of times and it didn't work, so I did a factory reset of the phone and tried again and it worked, at least on the application side, but after that my phone became bricked and entered an infinite bootloop...
I made some researches here and there and find out that to be able to unbrick it I just had to flash the 4.0.2.A.0.62 or the 4.0.2.A.0.42 firmware (the one for the Neo of course) using the flashtool, so I downloaded the firmware and the flashtool and followed the instructions.
The problem is, when I turn off the phone (by removing the battery et putting it on again), hold down the back button and plug the usb cable to enter flashmode, the LED on the side turns green (which is a good sign), windows make the new connected device sound but it tells me USB Device Not Recognized (Code 43 on the device manager)... The usb works fine, I mean I rooted the phone with so yeah... It only tells me USB Device Not Recognized when I try to boot it in flashmode or fastboot mode.
Any help would be really appreciated.
Best regards.
EDIT: I forgot to mention the OS i'm running, it's windows 8.1 and I actually don't have any other pc running windows 7 or xp to try things out on them. And right now I'm full charging the battery to try things again because I've read somewhere that it could be a problem too.

Indeed I do, this time when I try on the USB 3.0 I have the same problem but on the device manager it shows something else with the Code 43 but a message underneath it that says "A request for the USB BOS descriptor failed."

Sony Xperia E3; Flashmode; Problem;

Hello
I'm trying to get new software to my Sony Xperia E3 but computer can't see my phone in flashmode.(Fastboot is ok)
When I normally turn on a phone I can see boot screen (Sony, Xperia) and it stay on this.
I can see green light on phone but computer can't see it.
I'm using sony mobile flasher by Androxyde.
How I can solve this?
So, let's resume in correct terms:
-You tried to flash something using Odin but your computer does not detect your device.
-Now you got into a bootloop.
Is that correct?
No. Phone restarted by itself, started loading android and turned off.
It's everything.
Hello
if u are using windows 8 you must disable verification and then reinstall drivers
also try reinstalling drivers from the folder in the /flashtool/drivers folder
make sure you are not using a 3.0 usb port, it causes many issues.
Good luck!
