Unbrick Synology DS918+

Hello,
Since you mentioned that the file is exactly the same as bios_full.bin, I tried again using the CH341A.
After reading the chip, the contents matched bios_full.bin, and the checksum was also correct.

I completely erased the ROM, wrote the BIOS again, and verified the checksum.
However, even though the RAM is installed, I’m still getting the following error:
“Memory training fail, In a Dead Loop: Acting.”

I also tried replacing the RAM, but the same issue persists.
Do you have any idea what might be causing this problem?

Unfortunately, this is pointing to a problem with your RAM, or with the mainboard. In the experience of this forum, the only time you see the Memory training message is when the RAM is not detected at boot.
