k750i down after flashing error

Hey, really need your help.
So the problem is. I wanted to flash my k750i (yeah i was so bored and now i see that i am an idiot). So i tryed to flash it to w810. Downloaded all files needed (MAIN, FS) and i used XS++ for flashing. Well fist the MAIN instaled great, but the FS on file 114/161 had an error and the flashing and it said finishing.. because of that error.But it didnt finish,so i had to stop it. So i downloaded a nutter FS and try to flash it, same , now it was 114/165.
I couldnt turn my mobile on #@$!. Now i tryed to costumize FS. It stucked on 20:56:29| Activating GDFS.., every time. Than i downloaded MAIN and FS for k750i. The flash was complete with no errors. Tryed to turn on the phone, it's not turning on. Reinserted baterry, now tryed to turn on, it flashed and thats it, its off again. Tryed to customaze now. Again stuck un the Activating GDFS. Ok so i downloaded GDFS for k750i. Tryed to install it , again stuck on Activating GDFS.
The bigest problem is that I am an idiot because i didnt make backup.
Please help me. :(

You can't flash K750 to W810. Try to flash it to W800.

I just want my phone back worknig..
See that the flashing didnt work to get by phone back, so why would it work now.

Try to flash with SeTool. If it don't work, read this: REPAIRING EROM GUIDES for most sonyericsson phones

yeah, you should first repair your erom and then reflash it to W800i. everything will work fine. don't panic

k, ill try it, thank you

sorry for DP,
Now i now that GDFS is the problem, so i tryed to install a new one, but it says that thas a bad GDFS and there has been an error

I cant download from here a new gdfs for some reason. (I didnt use my limit(the 10 files in 3 days))
So if i flashad to w800i do i have to get a w800i GDFS or K750i GDFS?

it will be k750 GDFS before you flash it and w800 if already flashed

gdfs is a n independent for each phone in other words like persons name so you cannot change or put other phone gdfs in your phone even though it is k750 phone, if you have meddled gdfs of your phone then you are in soup, XS++ is good, hope you have not backed up your gdfs of your phone, before doing anything we have lots of tutorials in top sony, you need to read tutorials in top sony and then try flashing, now you need service cable to unlock and setool software or you can buy credits to correct the damge. good luck. please read tutorials!
