Hi All, 
   
 For the past few days with the help of the unlock procedure i am able to use Reliance CDMA sim with out having any issue in my HTC desire 510. 
 Yesterday got a system update - 1.48.652.2 (60.66MB).  
 update causes phone to reboot in the TWRP recovery mode and does not update. It keeps on popping for system update. 
 Please let me know, How to fix it?
