I have a PR2100 with 2x 3TB drives in a mirrored configuration and approx 1TB available space, running Cloud OS 3 version 2.31.204.
When I try to di a manual update to version 2.40.155 (retrieved from WD firmware downloads - https://downloads.wdc.com/nas/My_Cloud_PR2100_2.40.157.bin), I get an error message “Upload firmware failed. Try again.” with code: 1003.
I have redownloaded the BIN file from WD 3 times and tried the update 4 times, each time getting the same failure message. Additionally, I have restarted the PR2100 a couple of times and retried the update. The PC is connected to the same ethernet switch as the PR2100, so no connectivity issue.
Are there any specific log files I should look into on the PR2100 to see what the real cause of the problem is?
