Restore the back up you made of your emunand. Didn't make a backup? Should've read one of the threads that have been open for hours on the topic before doing anything.

i think i made a backup but i don't think it was of 8.1 , how can i do a back up anyway ?

Using the PC emunand tool that you used to make the back up, just click "inject nand" instead of "backup nand"
