[Q] system ui problem

I have looked everywhere for this, but cannot find it. I am not sure how, but the systemui.apk is no longer on my phone, and so all features that it controls are not working. Does anyone have the apk for the Note 1 N7000 jelly bean update that I can download? I am going crazy without my notification bar.

My kernel is 3.0.31-906407
dpi@DELL237 #3

Build number: JZO54K.N7000JPLSB.

I have done a factory reset, and tryed to replace it with apk's I have found. I looked at rooting the phone, but I need to ensure I have it till the 28th, when if I cannot fix it my husband will root it. Please let me know if you can help.

Thank you
Nikoah
