Pls help.

Flash and customize your phone again.

Flashed 5 times :)
Isn't work. Same problem. Try to back k750i firmware - no work.
Tryed xs++ v1.5 and can customize, but got error at end (xs++ close).

Use xs++1.2 it works with filesystem and with K750

The newer versions should work too. But well, try with XS++1.2, if it doesn't work try to finalize with SE Tool lite.

Ok.
Thanks to your fast answer.
Sorry for my tarzan english :)

Work!!! Just use XS++1.2 to customize.
Thanks!!!
