Original Firmware Help???

[jrodnay]

I have been trying to find the right firmware for this Asus zenfone 2e Z00D/Ze500cl. I recieved this device and it has already been rooted and is running AICP Rom built on CM 12.1 but it has no gapps, and is currently using TWRP recovery... I cannot find any firmware that is stock that will flash without errors due to the fact i guess AT&T doesn't appreciate unlocking bootloaders. Also I cannot find a gapps zip that will flash through the recovery correctly, If I can get gapps working that will be suffice for the owner. Can anyone help me figure out what he has done, or what can be done to either fix gapps or revert back to original fw? thanks in advance
