3. On the post where the firmware was mentioned, I was recommended to download a previous FW version, unfortunately to a domain that is no longer active… so, I ALREADY downloaded the BOOT software from the other new link provided… but as far as the firmware goes. …

https://ftp.anionix.ru/WDMyCloud/WDMyCloud-Gen2/ (Version 2.30.193).

The following Google Drive link is a mirror of the anionix.ru link (hosted by the same person)

One can download earlier firmware for their single bay/single drive My Cloud model from the following link:

UPDATE (4/15/2022): WD has terminating OS3 support as of April 15th of 2022!!! Generally one’s OS3 My Cloud will remain operational and accessible on the local network. WD supported remote access service (MyCloud.com / OS3 mobile apps) has been be terminated. The second generation single bay My Cloud ((P/N: WDBCTLxxxxxxx-10, FW 02.xx.xx)) unit is not affected by the OS3 support termination, the second generation single bay My Cloud can be updated to OS5. UPDATE: It appears WD is now blocking us…
