I wonder is it posible to flash back firmware (liteon LDW 811S) from HSOK to HSOE?

having the same problem i need to flash from fsoh to fsog have you tried the lite on forums lots of help there but for me it was too confusing anyone do it in english regards
mine is a ldw 411 s

or better still how can you resore default setting dont think you can use system resore

you should be able to flash back using th eolder firmware. if not you can do a web search for a little utility called " liteon flash" which will allow you to do that.
