我用upgdvd.exe試了很多次,永遠是target not found.
找了很多資料,從http://forum.firmware-flash.com/vie...9&view=previous發現,下載的pioneer dvd 120rd韌體有3個檔案
upgdvd.exe
atwis123.hex
refinq.dat
其中upgdvd.exe的檔案根本不能更新120RD到rpc-1,根據上頭的說法....

Important Notes for DVD-120RD owners:
1. UPGDVD.exe does not work on a drive with DVD-120RD.
(UPGDVD.exe is for upgrading DVD-120, e.g. from RPC-2 to Ver. 1.23 RPC-1.)
2. Flashing atpio123.hex (DVD-120, Ver. 1.23 RPC-1) by DVD10.exe upgrades DVD-120RD to the desired DVD-120 (RPC-1) in one shot and NO EXTRA STEP is required since the flashing already produced RPC-1 firmware Ver. 1.23.

以上是mjlee作者公佈的
大意是要更新DVD-120RD成為Ver. 1.23 RPC-1必須要用 DVD-120 (RPC-1)的firmware
使用方法如下:
UPG10 /N atpio123.hex
where N is your drive location.
/1 = Primary Slave
/2 = Secondary master
/3 = Secondary Slave
給想要破韌體的人參考

P.S.雖然我找到方法了,但卻不敢更新了, .............風險太大了
