Ldw 851s Not Working

HELLO GUYS,

I BOUGHT THIS LDW 851S 2 MONTHS BACK AND IT WAS WORKING FINE. I CONSULTED A FRIEND AND ASK IF HE HAS A SOFTWARE
FOR DISABLING THE REGION PROTECTION CODE AND HE GAVE ME THE “RPCDE2.EXE”. I RUN THIS PROGRAM TO DISABLE THE RPC AND THE PROBLEM STARTED. THE DRIVE IS NOT READING AT ALL.
I UPGRADED THE FIRMWARE TO “GSOF” BUT STILL NOT READING.
I EVEN TRIED TO RUN THE LTNRPC TOOL AND USE THE ENABLE AND DISABLE BUTTONS BUT STILL DIDN’T WORK. I EVEN USED THE
SET REGION BUTTON (LTNRPC) AND IT FAILED WITH THE MESSAGE “023A00 MEDIUM NOT PRESENT”.

CAN ANYODY HELP ME RESTORE THE ORIGINAL FIRMWARE OR PROVIDE ME FOR THE BIN FILE OF THIS LDW 851S.

I TRIED TO SEND IT BACK TO THE SHOP WHERE I BOUGHT IT BUT
UP TO NOW THEY DONT HAVE ANY AVAILABLE STOCK.

I WILL APPRECIATE YOUR HELP.

MANY THANKS TO ALL.
