RedMi 2 Bootloop after MIUI update
Ok here how I have managed to correctly boot the phone:


Boot in fastboot mode ( power + volume down )
Flash again CWM: fastboot flash recovery recovery.img
boot into CWM: fastboot boot recovery.img
reboot the system using CWM (fix root)
re-flash with flashify


step 3 is to be sure that CWM will be rebooted.
step 5 is to be sure CWM is flashed ( in the past I have experienced some problem flashing the recovery image with fastboot )

There is probably some other way but this way worked for me so it maybe useful to other as well.
