Problem with Stack Notification, the Top right icon on notification and home button not working (but still vibrating) in android 4.4.2

i have this local brand phone called 'cherry mobile flare 3' and its already rooted through kingoroot...

yesterday, the MicroSD got corrupt for 'i don't know' reason. T______T and i tried formatting it on my phone but as soon as i pressed format, it rebooted and freezed on its logo on startup ... so i did a hard reset and it luckily (not really) came back... but this time, the home button isnt working, the stack notification isnt working and the top right icon/button nowhere to be found (although, it comes back once in a while but still not pressable)... T_______T

also, i already tried resetting back to its stock rom but still no luck...

what should i do? some people say i should buy one but i really am on a tight budget right now... T________T

please somebody... help...
