Had a little trouble with this one, non starter, no Service Mode, just standby LED and response from Remote, but Bricked.
Main Board BN41-02534B Hawk-M-FHD-PR02, You will see a GD 25Q41BSIG SOP8@200, under Processor Heatsink.
Stange number, won't work in a 200 SOP8 socket, use a 200 SOP20 and you'll get read and write.
I used RT809H to do the work, BIN was dumped 3 time and verfied to be sure off aworking board.
Hope helps someone out, good luck to all.
