Thanks @Izzy. I was able to resolve the issue by using your suggestion. I tried some extra steps. I flashed "Aroma file manager" because that was not installed in my Phill Z recovery. One thing to note was that Aroma File Manager had to be flashed twice(using zip install from external memory); thus it allowed me access to /data/tombstones as well as /data/data/<Package_name>. I not only removed problematic packages, but also removed some clutter folders which were lying there unused. Viola! I would want to make this as answer If @Izzy can post this comment as answer. Thanks!

@Izzy Seems a good suggestion. Unfortunately, I am not that of an expert and my aroma file manager is not working right now. It says no cwm/aromafm/aromafm.zip in path'. Any help on getting that installed would be awesome. I do have adb and fastboot access but I am not that expert there either.

yes, i do have reason. Whole internet is able to root gt-i8262 with framaroot where as i am not. I rooted other devices n never faced any trouble. When i hit # drop SuperSU su to /system/xbin/su in cydia impactor, i get unknown error.
