Oppo Blu-ray player 其中一個強大功能是可以播放BD.iso檔案，但官方於上兩個firmware開始將此功能移除，此舉令一眾用家大為頭痛，因為如不upgrade firmware有機會不能播放新發行的Blu-ray，但upgrade了就不能播放BD.iso。
幸好近日網友benson26於影音論壇HiEndy分享了一個將Oppo Blu-ray Player的firmware downgrade的方法，方法如下:-
STANDARD/BASIC MOD:
1. Disconnect ethernet, and any USB devices and power up the player with no disc in the tray.
2. When it displays "no disc" wait for approx 4-5 seconds, and press GREEN-2-2 on the remote.
3. Press "setup" on remote.
4. Scroll down to "Device setup"
5. Place the bar on "Firmware Upgrade"
6. Press RED-8-5-2-0 on the remote.
7. Exit menu again by pressing setup button, NOT the ok button.
8. Now you can downgrade the firmware with the use of a usb stick, just follow the usual instructions from Oppo.
PRO MOD:
1 Disconnect ethernet, and any USB devices, and power up the player with no disc in the tray.
2 Press "setup" on remote
3 Scroll down to "Device setup"
4 Place the bar on "Firmware Upgrade"
5 Press RED-8-5-2-0 on the remote.
6 In this menu, press 1-1-4 on the remote.
7 Exit menu again by pressing setup button, NOT the ok button.
8 Now you can downgrade the firmware with the use of a usb stick, just follow the usual instructions from Oppo.
Obviously you'll also need the FW you want to reinstal...
NB: FW upgrades are not to be taken lightly, they sometimes brick your player. Do this at your own risk...or don't do it.
