[Q] downloading/sending media after root topic

Hello all!!
My note 4 has some problem! :( some apps don't work, for example, vr roller coaster wouldn't load, I disinstalled and reinstalled it...and it worked, however other apps, such as telegram or whatsapp won't let me download or send any media: videos,audio,pictures. It sais download failed when I try to receive them. Also, I can't download Facebook photos, nor can I download from dropbox. All of this has happened after I have installed twrp, installed infamous rom, and then restored from a Nandroid backup. ..this because it didn't recognizer my sim..what on earth can I do to get it back working like before?! Thank youuuuuu
