First of all, if you want to unlock your phone, check the date of manufacturing first! It is well documented here plenty of examples of newer phone brick when unlocking bootloader, so better be careful!
Secondly, if you ran into problem, you need to re-lock your phone using flash tool. Then re-unlock again! I previously lost my phone GSM radio when unlocking bootloader (while on GingerExperia). I have to flash into stock ROM (it's a must) using flash tool, and relocked again.
Finally, it is safest to unlock bootloader in stock rom.

No, you don't need to unlock it again. BL is the flash partition of the phone, what contains a secret code. When you unlock the BL, you'll remove the code and the flash partition will be open. When you flash a new ROM, it changes the system partition. When you flash a new kernel, it changes the flash partition but nothing else. So you'll not need to unlock BL again.

S1 Boot problems

HI Guys,
Today i tried 40 times to install S1 Boot drivers.
How can i make it work , cauze i want to install custom ROM.
Thx

You don't need any s1 boot driver to install custom rom, just root your phone install cwm and flash your custom stock rom. unlock your bootloader ( if you can) and you can enjoy cm10 aokp... All in one thread can help you

Thanks but how do i get in fastboot mode? For root you need to get in fastboot mode?

For enter in fastboot you need an unlockable bootloader but for now fastboot is just for flash kernel. But if you can't you can always root your phone on a. 303 firmware with flashtool install The cwm ( you can find it in dev theard) and flash à custom STOCK rom but you don't need fastboot or Just if you cant unlock your bootloader fastboot is not enable in thé phone so you cant flash cm10 aokp.... Whose need custom kernel

Are you trying to unlock your bootloader?
If so, there's a page of instructions in Sony website. The instruction page will provide a link to download Android's SDK and the S1boot fastboot driver.
Have you done that step yet?

1.) if you flash recovery in fastbot you no longer have a rom installed.
2) No need to root if youhave unlocked bootloader, just flash an unsecure kernel.
To fix this, flash my kernel (Follow the link in my signature) then flash the rom of your choice in recovery

Is your bootloader unlocked? You need an unlocked bootloader to flash a non-stock based custom roms. Since you can connect it to flashmode, download flash tools and flash back a stock rom. You can unlock your bootloader if you want flash flash a custom ROM.
