Boot Shell can execute Linux Shell commands and Shell Script Files(*.sh/*.txt) [Pro Version] at boot. It also has a very simple terminal built-in [PRO only].

Boot Shell act as an alternative for devices which have ROMs/Kernels without init.d support.

It does not have any predefined functions, but the commands you enter can make it a very versatile app with wide set of possibilities.

Some of its possible applications -
-Trim file system (fstrim utility, fix lags)
-Tweak GPU, CPU, I/O, Display parameters
-Load kernel modules
and a lot more

Completely ad/spam free and will always be.
