Need help resurrecting old Pirate Box

Alright so I made a piratebox out of a TP-Link TL-MR3020 a pretty long while ago (possibly 2-3 years ago ;D) and after a discussion with a friend about deaddrops (like USBs) I decided to resurrect it for fun! Problem is, I cannot access it.

I'm pretty sure (when it's working) you do not need to default IP in the address bar to access it like you would before installing openwrt, just any input into any browser will result in a redirect to the imageboard interface, correct? Either way, I have tried all and any input in the address bar to access it.

I tried troubleshooting it myself and came across a post about making an "auto_flash" folder with the openwrt-ar71xx-generic-tl-mr3020-v1-squashfs-factory.bin file and it seemed to be installing as it kept blinking and resetting and then returned to normal after a couple minutes, although this did not fix it I believe.

I also cannot ssh or telnet into it, here are the results:

Lukes-MacBook-Pro:~ Luke$ ssh root@192.168.1.1
root@192.168.1.1's password:
Permission denied, please try again.
root@192.168.1.1's password:
Permission denied, please try again.
root@192.168.1.1's password:
Permission denied (publickey,password).
Lukes-MacBook-Pro:~ Luke$ telnet 192.168.1.1
Trying 192.168.1.1...
telnet: connect to address 192.168.1.1: Connection refused
telnet: Unable to connect to remote host
Lukes-MacBook-Pro:~ Luke$

After attempting default passwords like "admin", "password", and "passwd", still no access. I did however assume the auto flash with a fresh install would reset any password I might have set previously.(?)

I WOULD try the instructions on the original post on the homepage but it seems I need to be able to access it via ssh or telnet before all else.

Any responses are greatly appreciated as it seems piratebox are becoming an obsolete project! Or at least less discussed (td)

Edit 1: Failsafe results coming soon...

Edit 2:

After following failsafe instructions here are the results:

  Use 'passwd' to set your login password

root@(none):/# passwd
Changing password for root
New password:
Retype password:
passwd: /etc/passwd: Read-only file system
passwd: can't update password file /etc/passwd
root@(none):/#

ifconfig wasn't cooperating (probably because in the video OP was using linux) so I made the IP static to 192.168.1.2 through System Preferences -> Network -> Ethernet

Once I was in I decided to change the password:

root@(none):/# passwd
Changing password for root
New password:
Retype password:
passwd: /etc/passwd: Read-only file system
passwd: can't update password file /etc/passwd

then found out I needed to mount_root before doing so:

root@(none):/# mount_root
/sbin/mount_root: line 1: pi_include: not found
/sbin/mount_root: line 1: pi_include: not found
/sbin/mount_root: line 1: set_jffs_mp: not found
/sbin/mount_root: line 1: determine_root_device: not found
/sbin/mount_root: line 1: can't create /.extroot.md5sum: Read-only file system
switching to jffs2
root@(none):/# passwd
Changing password for root
New password:
Retype password:
passwd: can't create '/etc/shadow+': No space left on device
passwd: can't update password file /etc/shadow
root@(none):/#

I interpreted the feedback from mount_root to be errors but after trying passwd again it seemed to work, but indicate that there was no space left. I do not have the USB connected… aaaand I just inserted it while in fail safe, tried passwd again and still says no space left...

Edit 3:

Just inserted the USB and went through the failsafe process again trying to change the password and ran into the "No space left on device" error.

I think I have ran out of experiments to test so here are the "example output for technical questions" info:
