Dead K750i after crossflashing

sorry everyone but im a newbie.
and as such i is ever so slightly confused.
everyone is offering advice with so many different applications.

i have tried xs++ but phone keep turning on between fs and customise.
so trying phone sx, main and fs flash fine but custamisation hangs on *****fs activation please wait.
i have read that there is no answer as to what causes it. have just tried customisation but bruteforcing has stopped at wait for EaTEbS.
if anone can offer a suggestion i would appreciate it alot

Hi. I need some help here too, to prevent me from having such problems as well.
I have a RED CID49 K750i, and I want to flash it to W800i. Should i download the files named W800_R1BC002_FS_AMERICA_2_RED36 or W800_R1BC002_FS_AMERICA_2_RED49 to flash my phone?
I've found threads that tells us to slide the CID36 files with GSlide and then flash it with XS++.
Or can I just use the CID 49 files and flash it directly into my CID49 K750i?
Please reply ASAP.

yes, if your phone is CID49, you can downloald the firmware which has CID49 and directly flash it with XS++ 3.1 but in this order FS, custpack and then main. everything should went fine. have a nice day
