LG flashed to LibreDrive no longer recognize BluRay - Orig. Firmware lost

[kapqa]

Hello ,

i have a request please;

since have flashed a LG Drive NS55 to supported firmware for UHD NS60 with the shared firmware here on the Forum;
it functioned for 1-2 Bluray but was noisy from the start after the new firmware was applied;

now it seems, the Drive is no longer recognizing any Bluray discs at all; DVD are still recognized;

i would like to attempt to restore the original Firmware, but unfortunately cannot find the saved file any longer;


if any of you can help, would be glad, maybe the drive could retain functionality of reading normal non-UHD Bluray and writing to Bluray with the original Firmware;
otherwise, would have to consider the Bluray functionality as lost on this drive;


Thank you

changing fw will not cause a change rebooting the drive could
turn it off for 5 mins then power backup and see if it works if not clean the lasers
if it still does not work after that the Blu-ray laser died lg/asus rebrand drives have been extremely unreliable

sorry , i have made a mistake, the drive in question is a CH12NS40;
will attempt to restore original firmware.

edit> attempting to flash original firmware not succesful, since ODD app says it has alreaadyu latest firmware applied.


maybe someone can share the original firmware, file to flash for windows thanks,
it should be like

N1.01_CH12NS40_171121_only_NOBJ.exe

Hello ,\

i would kindly need help with downgrading the firmware if possible<
have now found the original firmware .exe from LG for the drive,

but it would not allow me to use it since the drive is not recognized as CH12NS40 but now as WH16NS60

found the download links here

nevermind, could flash back with the help of this firmware package here CH12NS40 1.01 or 1.03 included<

but would still not read any Bluray<

would it make a difference if could use DOSFLASH as shown here

would like to restore 1.00 but donT know how since the dump is in .tar file and not .bin.



thanks.
