mobile

Dear all,
I updated my moto e 1st generation to Lollipop 5.0 successfully. I used mobile for one week. After i decided to install Android kitkat stock firmware again to my MOTO E. I installed stock firmware to my moto e by following guidlines from

mfastboot flash partition gpt.bin
mfastboot flash motoboot motoboot.img
mfastboot flash logo logo.bin
mfastboot flash boot boot.img
mfastboot flash recovery recovery.img
mfastboot flash system system.img_sparsechunk1
mfastboot flash system system.img_sparsechunk2
mfastboot flash system system.img_sparsechunk3
mfastboot flash modem NON-HLOS.bin
mfastboot erase modemst1
mfastboot erase modemst2
mfastboot flash fsg fsg.mbn
mfastboot erase cache
mfastboot erase userdata
mfastboot reboot

everything went well, it has to restart automatically but it has not restarted at all. Now situation is that if we try to power On the mobile by pressing power key it doesnt show anything. Only notification LED blinks continuosly after pressing power button during charging only. Now on display nothing is coming except notification LED. I tried for charging mobile for 4 Hrs. continuously but during charging also nothing is displaying on display. If display comes then only i can try again for installing stock firmware. I also removed battery after unscrewing the mobile back cover and waited for around 2 Hr. Then again i fixed battery connectors then tried again nothing responded by mobile. I think my mobile is dead but i know you are great developers who can suggest best methods to solve these type of issues. please write me how can i solve this problem..?
