I want to unlock ythe bootloader of my Xperia U. So I went to the official site of Sony and followed the instructions. I got the unlock key too. I installed the SDK and I installed the drivers given on the Sony's official site. I copied them to usb_driver folder. And now when I try to enter my phone in fastboot mode, i.e. when I swtch off the phone and connect it to my laptop with the fastboot button long pressed (volume up key in Xperia U's case), instead of prompting me to install the drivers, it says USB device not recognized, it maybe damaged etc.. But my phone connects to PC when it is switched on. I can transfer files too. Means, the USB cable is alright. I tried with one more cable but no luck. I have Windows 8.1 installed on my PC. I've never tried rooting or something like this before so I have no idea what am I doing wrong. So, please help me.

Have you installed the sync program for your phone? If so ensure it is NOT running and try then as it will grab the USB ports before you try using adb and fastboot.
GT540 - E320 is poorly

i dont have the sync program of sony. and its still doesnt work.
You may be as well to uninstall all drivers for phone, reboot your system and install drivers afresh, even connect phone and in your systems device manager remove the phone device from your system.
Sometimes drivers can get cross references when installing multiple times

Another option is if you have access to Windows XP 32bit as I have heard of problems with 64bit etc

there is no other way to delete everyting and start all over again?

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?)

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.

Can you help me how you did it using flash tools?
Hello Experts,
This was the best phone I ever owned. It has best in class features (camera, touch, perf ..n ofcourse cost etc.). After the eight month of mighty use i got notification from "SUS" that ICS is now available on your device. Tried Upgrading but in next hour it was showing me touch/hang issues. So reverted back to 2.3* GB.
After a month someone said try manual upgrade of 4.0 using SE flashtool. Tried and result was almost same just that this time it was random.
Again thought of going back to GB. It worked. Used Device for another month without issues. And one night suddenly it went dead. Thought that could be the case of out charge. Did Charge using USB Cable/Power cord method but result was same. It never booted after that.
One day thought of connecting my car charger then it shown "RED" LED indicator. searched on google, someone said battery issue. Tried replacing battery with same model phone which my friend owns. But Result was same.
Finally went to Sony Service Center (Pune, India). They said phone cannot be recovered. I asked them to replace whatever it takes Upto.
Since phone was brought up from import method i couldnt claim warranty.
Sorry for the long email, now question to the experts here
1.) Can this phone recovered? I tried SUS/Flashtool my phone is not getting detected.
2.) Is there any possibility that Motherboard/chips can be replaced to get this phone into functional state.
3.) Anything else can be suggested. (Except buying new phone . i already own Spice CSLMI410)
Can u use ur device in flashmode or fastboot mode?

guess it was sorking anyway, it looks your kernel is fine, so check in flashtool if the device connects not in drivers list
if it doesnt connect, unpack ftf you can see some system,data and so on image files flash them via fastboot(unlock bootloader)
if when you press and hold the volume down button while pluging the usb cable in, green light just lights up, it means there is hope bro :good: I believe after that, you need to go to a folder named something like "x10_libraries" in the flashtool folder and need to find fastboot.exe. oh, at the same time, you should download a kernel suitable for you device which includes cwm recovery and copy that .img file to the same folder from the last sentence. then you should write(in cmd of course) "fastboot flash boot something.img". I believe it'll work, at least no harm to try and I guess this is the last possibility for your beloved xpeia...
I bricked my phone. I had my phone rooted and installed a modified rom based on .89 compilation. I wanted to change to one based on the 100, and after install it I lost install this kernel root. Then I tried to root the phone again but the flashtool did not recognize the phone. I was advised to do so through the Fasttool and I did. I installed the drivers for fastboot and then I did:
fastboot flash boot boot.img (boot.img was along with the rest of fastboot files). After "fastboot reboot" and the phone was shut down and no longer has reignited.
Now the only thing that appears is a green light turns off immediately and nothing else. The flashtool still do not acknowledge either the computer now.
Can you help?
Try to flash stock firmware again if flashtools doesn't recognize the phone try to restart your pc after install the driver. I have this problem before .and it still connect 2 flash mode. If that doesn't work try on another pc

It's an Xperia U. Now only the frontal red light comes on when I plug the computer. The LEDs do not light neither with vol + or vol -..
Take the battery out for a minute and try flash mode or fastboot mode again.
Do not just plig it to the PC before you do.
Please try this proven way to install fast boot and flash drivers

It's fixed. In a laptop with windos xp I tried to follow the last instructions of nosmaster but could not install fastboot drivers. Then I decided to install PC Companion to see if this installed the drivers from the phone directly and not only installed the drivers but updated the phone and finally returned to work.
Thanks to all

No, that's not possible
I guess you should try reinstalling all drivers from flashtool for all devices, or try installing PC Companion or SEUS. If that's not working, open the windows device manager and uninstall/update the drivers for your phone when it's connected
