Hi.

After installing OpenSSH server, you can "ssh root@localhost" to enter root shell.

Command sudo asks for user password, not root's. There is no user password set by default, but you can define one by yourself in root shell with command "passwd user". You also have to define which programs the user may run with sudo. This is done by editing /etc/sudoers file. For example, if you want to be able to enter root mode with using su (writing "sudo su -"), you could write the following in root shell:

This adds a line in the end of /etc/sudoers file, which allows you to use command su with root permissions. You will be asked for your password every time you use this. If you don't want to write your password, you should write instead:


Gainroot is a script, which is supposed to let you in root shell without installing SSH server. As you already noticed, this normally works only if you have enabled special R&D mode when flashing the OS to your tablet. However, you can install a package called "becomeroot". This edits the gainroot script so it works even without R&D mode enabled.

Red Pill mode is a hidden feature in the Application Manager. It gives you more options, for example you can install software which is not in "user" category. However you should remember that in Red Pill mode it is possible to break package dependencies and brick your device.
