I'm having trouble downgrading.
This is what I've been doing so far:
1) try to install 5022
2) wait for it to fail and mention telnet
3) log in with root using 101-0101 as password
4) edit VERSION with vi, ensuring buildnumber is "5021"
5) :wq to save and quit
6) type reboot
7) reboot into install/update mode
However at this point the build number has reverted and when I try and install via Synology Assistant it tells me the current version is still 5565 and that I need to install a newer version.
What am I doing wrong that the build number reverts during the reboot?
Thanks
