First, let me say that I'm sure this question has been answered. I know it's annoying to have new threads covering old topics pop up, especially from someone new. I promise, though, I did search...I just didn't find a clear answer. In fact, searching is what helped me find the instructions for reverting back to the original Pogoplug firmware, but none of the threads I found answered my question. Here's what I did on my black E02:
1.) Installed Arch Linux per the instructions
2.) Decided it was more than I needed
3.) Removed the USB drive containing the AL install
4.) Used SSH to log into the device and then:
mkdir -p /tmp/pogoroot
mount -t jffs2 /dev/mtdblock2 /tmp/pogoroot
mount -o remount,rw /tmp/pogoroot
vi /tmp/pogoroot/etc/init.d/rcS
[use "j" key to navigate down to line]: #/etc/init.d/hbmgr.sh start
[with cursor under # in front of light, use "x" key to delete]
[use ESC to leave insert mode and go back to command mode]
:wq
[RETURN after writing (saving) and quitting above]
mount -o r,remount /
/sbin/reboot
5.) Went to http://my.pogoplug.com/ and everything seemed good.
However, I want to verify that I'm truly back on stock...if Pogoplug decides to update the firmware, will I be able to install it automatically without bricking my device?
Also, I made this thread instead of bumping one of the other ones because I didn't find a single thread that wrote out the instructions like I did above. There might be one, but since I didn't find it, I thought it could be helpful to others in a position similar to mine in the future. I apologize if I wasn't supposed to.
Thanks in advance for your help and advice!
