I tried to delete ES File Explorer from my Lollipop 5.1.1. I have a system root and the explorer was a system app. In Link2SD app, it said frozen, so I thought it might be useless to keep it.Anyways I preferred the default system app and root explorer.
I tried to delete it and then all the system apps stopped working, and on rebooting my phone (SMJ 200G), I saw very few system apps, I could not install apks, and message app was also crashing. Also SuperSU was gone from launcher.All other installed apps were there. I factory resetted my phone with TWRP's default wipe; starting the phone now, I can not even log in. It asks me to select language, and then it says that Settings has stopped working.
What is the problem? What do I do? Whatever the solution is, please provide a guide too.
