Nitropad: Factory Reset

I have not run Nitropad in a while, but I forgot my disk password and user password, so I am trying to do a factory reset. However, when I do the OEM factory reset, it seems that /media is set to read-only when gpg is reconfigured, and I cannot copy the asc file. I was thinking of running “mount -o remount,rw /media” from the busy box to change the permissions, but the permissions are not changed properly and it does not work.
