I have some problems with my NEC 2500A.
I bought the NEC 2500A with original firmware 1.06 on it. I tried to upgrade it with the original nec firmware to 1.07. It did not work, I always got the message that my firmware is corrupted.
I tried several firmwares und flashing prgs and finally succeded to upgrade to the dangerous brothers hacked firmware. (1.27)
I have no problem in writing CDs but I have some in writing DVDs. Therefore I tried to return to the original Firmeware (stock106.bin).
My problem ist that dos (nec2x00a.exe used in dos enviroment) and windows firmware flashing programs wonÂ´t accept any change of the firmware.
The error message is: “Checksum error, fimware corruped” and the process of flashing stops.
With the hacked firmware my warrenty is void therefore I cant return the DVD-burner to NEC.
Has anyone an idea how to return to the status that I can change the firmware without getting this error.
