Hey guys, so I rooted my Nexus 5 today and it was done successfully. So before flashing it to CM, I backed up whatever I had left of the stock ROM. After that, I followed the normal procedures and installed Cyanogenmod. I booted it and CM worked fine. Then I installed GAPPS and booted it again. Everything worked fine. Then I decided to restore the backed up files of the stock rom. After that I went to the reboot option and clicked 'No' by mistake. And then the 'Android' logo popped up twice and returned to the recovery mode. So I rebooted it, and instead of CM icon coming up, the stock start up sequence kept on happening. And after a point it turned off and hasn't been turning on since then. So I need a solution to this problem. Thanks in advance.
