How to flash a zip file without signature verification?

Question

I have lenovo a3300-gv running android kit-kat. I tried to flash a .zip file in it using flashify. But it fails to flash as signature verification fails. I read some articles stating to flash in CWM/TWRP recovery to avoid this error. But I can't get custom recovery for my device. So, is there other way to flash in stock recovery without signature verification?

Answer

I'm afraid no (no easy one). As you have no custom recovery for your HW platform there is chance you can't rebuild a firmware for your phone. Bypassing this signature is possible only by modifying the source (actually this is what is done in teamwin or clockworkmod recoveries).
