I wanna unlock bootloader on my XSP but every time I connect it in fastboot mode, my pc tries to reinstall ADB drivers. I can put in download mode, I can push files in both sdcard0 and sdcard1. What can I do?

Did u read the tuto of Doomlord again?? :D . I give u a trick:

7. Extract fastboot_with_Android_USB_file.rar and open fastboot folder
8. Hold SHIFT and right click on the background of the folder
9. Select 'Open command window here'
10. Connect your phone in fastboot mode (turn phone off, hold Volume UP button and plug in USB Cable) [make sure drivers are installed as explained above]
11. In the cmd windows type in fastboot.exe -i 0x0fce getvar version
12. If a value is returned (it will return 0.5), it means the phone is correctly connected
13. Type in fastboot.exe -i 0x0fce oem unlock 0xKEY and replace KEY with the key which u received earlier.
14. You're device should now be bootloader unlocked

EDIT: I hope it helped ya :highfive:

EDIT: This process is delicate. If u dont know what u are doing, is better u dont do it for prevent one beaty BRICK :highfive:
Yes, I read it, but if I can't go in fastboot mode, I can't do this procedure. I installed flashtool drivers, but I still have this problem...

XP. But I unlocked bootloader also on Xperia U, I don't know why I have this problem... I remember I had problems with fastboot drivers, but I resolved in a few minutes...
Try this lil tuto:
1. Open the Windows Device Manager
2. Connect to phone in Fastboot mode (phone off -> Volume + key pressed -> connecting cable)
3. Connect your phone and ignore Windows messages. Quickly go to Device Manager and look for that just appeared "S1Boot Fastboot". Right click and click "Update Driver Software", once done you can relax, you can release the Volume + key and disconnect the phone. [NOTE: If Windows is trying to install the driver, you will not see "Update Driver Software" until it stops, so hurry].
4. Click "Search for driver software on your computer"
5. Click "Choose from a list of device drivers on my computer"
6. Select "Show all devices" (or something, I can not see the exact text)
7. Click "Use Disk ..."
8. Click "Browse ..."
9. Select the android_winusb.inf (in the folder with Fastboot usb_driver the USB drivers) and open
10. Click "OK"
11. If you get a list of 3 devices, choose "Android Bootloader Interface"
12. BEFORE pressing "Next" you need to reconnect the phone in fastboot mode, here you have to be fast again. Unplug the phone if you had not done before. Plug it back into fastboot mode. Once you do click "Next" on the computer.
13. If you followed the instructions correctly have the drivers installed before the phone was disconnected again.
14. Now you have the drivers installed, the phone will not slip out of Fastboot mode and everything should work properly.

I hope it works for ya how it worked for me :highfive:
DONE!
But, I was trying to unlock bootloader. Where I can see if it worked? Now I see that my sdcard0 has formatted with internal data. But I'm trying to install CWM with a kernel.elf (autoroot & CWM) using Flashtool. But... Flashtool says that I must be rooted before doing this. WUT?

Edit: I also see that I lost DRM keys, but I've got a backup to restore them. So... bootloader is unlocked!
Edit: RESOLVED! I restored DRM keys before flash kernel.elf, and it was wrong. So I repeated the procedure without DRM keys and... beautiful CWM with root :D now I think I can restore my DRM keys. Heheh
