Although i dont posses much knowledge about technical aspects of flashing and stuff, but somehow i successfully installed a custom rom using the guide on the following link
when i tried to install zip file of google apps the operation was aborted.
Then i tried to update the CWM from 5 to 18.104.22.168 using a zip file i downloaded (https://www.androidfilehost.com/?fid=23269279319200003)
This update failed and gave a blue screen of death. Now every time i go into recovery mode by pressing the power and home buttons it shows the blue screen of death, then i have to press the home button a couple of times to reboot the device.
Kindly let me know how to fix this blue screen issue.
