in my case after flashing rom and gapps the setup crash always.no problem without gapps
what i did was first install the rom only boot into it set it up then again go into the recovery and flash the gapps. thats how the instructions were and it...
Do we need to flash 5.1.1 Gapps?
yeah we need to flash 5.1.1 apps
micro apps package didn't install due to insufficient space. so nano or pico.
