Mind u the phon is working normall nothing seems bad.and i have don factory reset many times but still yet no show

The first time i rooted my n3, it took me close to 4 days to successfully root it. But so far, i can tel u dat i av successfully rooted my n3 two times without breaking a sweat just because i had to reset my fone for one reason or the other. Just follow these steps after reseting ur fone. Make sure you don't instal any other app apart from root checker 1st, superuser 2nd. Dont open the apps afta instalation. Then instal your poot which will require you to download ministro and its other stuffs which is 10mb in size. After these have been done accordingly, then, go to ur poot and press poot. Your fone wil turn off. Remove the battery and restart it. After booting, go to ur root checker to verify your root access. Follow these steps one after the other then, you are good to go

I have done this severally..this was the first step i used to root it before.....poot is not workin on the phone..i have deleted ans reinstall but same thing ..erro messag, sub binarry not written..at times it wil show get root cheacker and super saver and sub binarry not written same time..if i tried to check if its rooted it wil say not rootd
