Hello and good day.
i hope i can find here some help.
SHORT FACTS AT THE END OF THE POST
my phone went to bootloop after i applyed a backup i made with titanium backup.
sadly, i also restored all system files and my phone went to bootloop when i restarted.
xperia v lt25i with fastboot installed and the bootloader is unlocked.
so as much as i know connecting it to the pc pressing the volume button down the green light goes on and it should be the fastboot mode.
pressing the volume button up and the light goes blue should be the bootloader.
the problem is the phone only stays for 2 secounds in this mode and then going into the battery load mode.
this leaves not much time to install the device drivers on the PC (windows vista)
i managed to install the fastboot driver and now the phone stays +30 secounds in fastboot mode and switches then into the battery mode.
if i try to install the bootloader drivers for the device, he tryes but aborts the install saying "wrong parameter".
during the install he switches from the bootloader into the battery mode.
i installed the android sdk, flashtool(sony mobile flasher), universal adb driver, sony update service,sony pc companion.
sony updateservice says the OS is modified and refuses to update.
the sony pc companion repair function only seems to work with a started phone.
also i somehow manage to get the update/repair function started but it suddenly closes when it downloads/prepares the operation.
connected with active bootloop to the pc he finds the LT25i and wants to install the drivers "sony sa0106 ADB driver interface" but aborts with the reason "wrong parameter"
I had this too before i puted my phone into bootloop.
seems normal coz sony pc companion needs to install the drivers on its own.
when i go into the fastboot mode and open the sony mobile flasher, select in the fastboot toolbox to check the current device status he isnt doing anything.
in the android sdk using the fasstboot tool over the console he shows nothing when giving the "fastboot devices" command.
with "fastboot update" or "fastboot continue" he says "waiting for device" but gets stuck in it.
please if you have any advice what i can do or try or even a solution on my problem let me know.
i would be very happy to solve this problem.

iam a total noob when it comes to programing but 4 days ago i succesfully repaired the phone with a broken touch-lcd screen.
so if a possible solution requires a hardware mod-hack i have good experiance with even soldering smd components with a solder-needle.
LONG SHORT :
bootloop
Bootloader driver doesnt install on the PC.
Fastboot seems to give no response to commands.(in the windows device manager the device is installed as "SEMC flash device")
EDIT:Still trying to get the driver for the flashmode installed with the error "wrong parameter".
may seems to be a windows problem, maybe caused by old driver garbage but i have no solutuion.
How do i get the phone operational again?
Thank you for your time.
