I upgraded the firmware in AOC-USAS2LP-H8iR to the latest firmware posted in your FTP site. The upgrade was a success, however, after the reboot, the firmware can’t be initialized. I tried to re-flash the firmware again, but it complaints that no compatible device was found. I read an online article talking about the firmware recovery may help. What’s the procedure of the firmware recovery?
Below is the firmware recovery procedure for your AOC-USAS2LP-H8iR controller. Please use MegaRec to perform the firmware recovery.

Please obtain MegaRec utility from the following download link:

Extract the utility and put it along with the 8MB firmware ROM file into a folder in a bootable USB flash drive. The 8MB ROM file can be download from

Please boot to DOS with the USB flash drive, and run the 1st command:

"Magarec -adplist"

This is to confirm the MRCard ID number. The first card’s no. = 0. Now, run the 2nd command:

"Megarec -m0flash 0 AF_210~1.rom"

Please use dir command to find out in DOS the actual filename of the 8MB ROM file, first.

Do NOT interrupt it or restart the server. Wait until the firmware recovery procedure comes to a full stop. Hopefully, this will help to recover the firmware and restore functionality of the card.
