[Help] How to Downgrade back to TOS 5, from TOS6

Hello,

I didn't realize apps in TOS6 couldn't use remote mounted folders, so I need to go back to TOS5

I know I'm going to have to clear out all of my data, no big deal....

is there a guide or something on how to do this? I'm guessing I'm going to need to pull the internal usb out, and put TOS5 on it?

Any help would be great

Thanks!

NAS does not support downgrading.

If you need to, you can format the hard drive and reinstall the system from scratch.

First, create a TOS 5 boot system:

viewtopic.php?t=6433

Then, install TOS 5 by reinstalling the system:

viewtopic.php?t=423
