Yifeifan 16x DVD returns to life

I have not used this DVD drive for a long time. When I tried to reinstall the system in the RTM version of Bt vs2k5 in the past two days, the optical drive could not recognize it! Where can I borrow a disk from my roommate? I can't recognize it. I'm dizzy. Is it like this?
Since I bought this DVD, I usually only use it to install the system due to poor reading ability. I have not even seen several DVDs. Is that bad? My heart is unwilling, So I went online to search for the optical drive materials. After I learned it, I would like to open it.

Step 1: Upgrade firmware
The firmware of the optical drive is equivalent to the BIOS of the motherboard. After you find a suitable version and upgrade it, You can enhance its disk Reading Capability and compatibility with the disk. However, in the past few days, the company has closed down and has not obtained a proper version after finding N for a long time. Finally, download a 5dvc version of iis16xp. After upgrading it with winmtkflash, start the system and the BIOS will crash during detection.
A piece of cold sweat emerged from my mind, "No, my machine will be over it like this", hurriedly removed the optical drive from the machine, and then boot, BIOS finally passed self-check, the system is started normally. It seems that firmware failed to refresh. What should I do?
You can use mtkflash or winmtkflash to upgrade the image even if the BIOS does not detect the optical drive. But where can I find the appropriate firmware version? I didn't back up the data during the refresh process. I couldn't find a suitable version on the Internet. Isn't that my DVD is over?
No matter what it is. I downloaded the firmware of different brands, such as aesthetic, Pioneer, and Sony, to refresh the results. Either the system prompts that the firmware is not an appropriate optical drive, or the system does not pass the BIOS self-test after the refresh is successful. It seems that there is only one more path: Find a DVD of similar products, and back up a firmware to upgrade me!
As a result, when I went online to find my classmates, friends, and netizens, I was lucky to find them! Alas, is it so hard for me to win this one? When the mountains are exhausted, A friend sent a picture of the high-end DVD, saying: What should I do with this? I looked at the pictures, except for a few more 16 x
Word and brand are both the same. From him to the firmware address of ondata (http://www.onda.cn/pro/download/biosexp.jsp? Item_id = 1057), a version of 2.62, restart to DoS (in the bios, block the IDE where the optical drive is located through BIOS self-check), run mtkflash 4 W ondata. hex, after the refresh is successful, restart, enter the bios, and check the optical drive ...... after several dozen seconds of anxiety, I finally passed and finally put down my hanging heart!
Not complete, this time BIOS finally shows the model of this DVD: ide DVD-ROM 16x2.62, and I did not refresh firmware almost. Why did it not display MIDA *** in the past? After I use ondata to refresh it, I should display ondata! For now, regardless of it, and then on the Onda home page, the next version of firmware to brush, the results of BIOS also passed the self-check, display: on data 16x DVD-ROM, it seems that this time has finally been completed.
Conclusion: The exclusive 16 xdvd and the ike16 xpdvd are different. The former cannot be refreshed using the firmware of the latter. In addition, through my experience, I can say that the 16 x DVD is from OEM Onda! Therefore, if you fail to refresh the 16 x DVD, you can try it with Amada, and you may be able to get back to life. ^_^ (Note: After you brush 2.94 of Amada, the DVD has a code lock. I think it's not hard to solve this problem)

Step 2: Clean the laser head and power adjustment
After firmware is refreshed, my DVD drive still does not work properly and I cannot read a few discs. It seems that I had to clean the laser head and adjust the power according to the data.
I don't want to write about this step. I have a lot of online information. I also step by step. With a little luck, I finally achieved success. Really: I'm sorry, Pudu public Optical Drive

Now, I can't read the previous disc into the optical drive, then the optical drive is singing and dancing, I'm so happy:
Have fun & good luck!
