There was some problem with my 1-yr-old Moto E 1st gen. It got dead and after some time the dead android guy appears with some red-blue thing on its chest. It appears for half a second. I pressed Power+volume Down and menu appeared saying 'Device locked status code 0'

Somehow I unlocked it using Minimal ADB and fastboot. Then it said 'Device unlocked status code 3'. On opening it shows window saying 'Bootloader Unlocked'.

Then I tried to install firmware 'RETAIL-DSDS_CONDOR_KXC20.82-14_cid7_CFC_1FF.xml' flash images whatever they say. But in every command it returned 'Failure' and not 'Okay' as expected. Now phone is at is, with dead android guy appearing since yesterday. Please Help.
