Flash a ROM without using recovery mode

Question

I have an LG Prada 3.0 p940, running Android 2.3.7.



I have a problem accessing recovery mode. Is it possible to flash CyanogenMod ROM on stock ROM through PC without installing custom recovery?



Does anyone know a software that is trustworthy to do that, or to back up my current ROM?

Answer

No. You can not delete the system while it is running. If you have root access, you could "program" the stock recovery to flash your custom ROM on the next reboot by using a specific command line in a terminal.



There is LG Flash Tool for your device, but it is not official.
