Default No Alphabet

Hello Friends
I encountered a weird problem on my nex5
All was going well. I was on stock rom 4.4.4 with xposed and gravity box and then i updated gravity box
after reboot i was amazed and horrified to see that there was not a single alphabet on screen.
All i could see was jst image and icons .
I wiped cache and dalvik-cache but all in vain .
After that on the update apps screen there was a loding circle but no text
Any help.
I will try to upload some screens.
