How to install custom recovery on Micromax Canvas Nitro A310? I am unable to flash anything from recovery mode on my rooted (kinguser) android 4.4.2 (micromax canvas nitro A310). Red triangle with exclaimation mark &amp; unable to do anything, even not able to perform "User Backup". Shows error - write error, short write.

Can somebody help to delete stock recovery &amp; install custom. CWM recovery does not have updated custom recovery for model A310 (android 4.4.2).
