need help with flashing stock rom

hello, long time didnt touch my nexus 4, and here are the details:
nexus 4
android 4.4.4
kernel version: 3.4.0-perf-ga6edd5e android-build@kpdm5.cbf.corp.google.com
no root
recovery: CWM v 6.0.2.0

i tried to flash the latest stock rom without success, theres 5 img files that need to be flashed while CWM can't flash img files.
also i cant connect the device to my pc (i think the usb plug of the nexus is broken or something..) so i work with air droid.

what should i do? i want to get the device running latest stock rom + stock recovery or at least latest stock rom + twrp
thanks!
