LG GSA T20L Firmware Read-Out and Flash-In?

Hello,

is it possible to Read-Out (Backup) a firmware from LG GSA T20L (Laptop Combo) drive ?
And moreover can I write it later back ?

I want to test a other (newer) firmware but I want to save my actually firmware of this drive.
If this other Firmware isnt so good than I want go back to my original firmware.

Is it possible and if yes where can I get the programms for that ?

Thanks to all

As far as i know, there is no tool that backup or write firmware for LG drives.

Ah ok , thank can you tell me is it possible to flash E50L Firmware on T20L drive ?

I dont know about that, but you can ask in the MCSE forum.
