Micromax A110Q shows blank screen after waking up I am using Micromax A110Q. It turns on perfectly and displays
 everything fine. But whenever I turn off the screen or it sleeps
 automatically, the next time I press the power button to do something
 screen doesn't display anything, although the button icons on the
 touch-pad lit up.The device was working fine before I made the following changes.

I rooted the device and installed CWM and uninstalled some of the default apps offered by Micromax. Then after installing a few things I made a backup using CWM and then again flashed my device with v2 of the stock ROM (I was learning the basics of flashing).

I then used CWM recovery to undo the changes i.e.I restored the backup which I made just before flashing. Now when my mobile boots it sometimes display:


  Unfortunately, com.google.process.gapps have stopped working


but the problem persists even when the error doesn't occur.

How should I resolve the issue? And let me know  if you need other  details.
I didn't understood the logic behind it but I followed the following steps out of instincts and now the cell phone is working fine.


  
  Reflash the android with v2
  Boot in recovery mode.
  Go to recovery and backup
  select advance restore from sd card 
  Select all images except boot
  Start restore
  After restoring reboot
  


The system works fine after this.

If anyone can explain the logic behind this kindly reply.
