Problems with keyboard input method

i have bad bad problems with my meizu m8.

help please guys!!

i installed international keyboard but it wasn't good for me.
then i installed touchpal (free trial).

i followed instructions. i opened "control.exe" (it is under "windows" folder) and i choosed "touchpal" from "imput method" menu.

touchpal was good and it worked well. then i deleted internation keyboard from his folder.
maybe i did some big mistake and i deleted either the standard default keyboard installed when the phone was new.

now there is this big problem. when i want write sms I CAN'T SEE the keyboard. no standard keyboard, no international keyboard, no touchpal keyboard.
i reset the phone but it couldn't help.

i'm not able to write sms anymore.

anyone help me? i'm crying...

maybe i could re-install the firmware? i fear to do a worst thing.

how could i re-install the right firmware? mine is 0.9.3.8
