Need DVD firmware upgrade for Inspiron 3800 with LG DRN8080B

I have an Inspiron 3800  with LG DRN8080B installed.  It cannot read DVD+R, RW.  I did find the Firmware update v. 2.02 file which is supposed to solve the reading errors of DVD+R/RW's.  However, the compatible systems listed do not include 3800.  Where can I find a version that's compatible with 3800?  Or am I supposed to use the same firmware for 3800? 

Here is the link: http://support.dell.com/filelib/format.aspx?releaseid=R40054
Release Title:  Removable Storage: HLDS 8X DVD Slim-line DRN-8080B, Firmware, Multi OS, Multi Language, Multi System, v. 2.02, A03

I assume HLDS is the same as LG?? 

Is there any risk I may crash my system if I install this firmware update?

Thanks in advance for your help!
