[Q] unfortunately, the process.com.android.systemui has stopped on my Note 2 (N7100) topic

Hi i am at wits end and wondering if anybody can help. I have a N7100 which was ok untill a couple of days ago when it started a draining battery problem, overnight from 95% to turned off in the morning and when i turned it back on it was at 3%. So i changed my rom incase it was that, but it still continued to drain. I have some how manage to unroot my device and Odin isnt recognizing my note 2. At the moment i have a phone that bleeps every so often and when i reset it it comes up with the unfortunately, the process.com.android.systemui has stopped error. Also when i press volume up, power button and the bottom button i dont get TWRP any more i get Android system recovery (3e). My computer recognises my sd card and my phone. I have checked numerous threads about this and nobody seems to have the same problem. Hope someone can help?
