| + | Once you run **adb shell** on your Android, from any other device connected by usb to it, make sure you are root (run **whoami**, **id** or similar), otherwise you might need to run **adb root** first, but sometimes you only need to enable the "ADB as Root" option in developer options. | ||
| + | |||
| + | As it is a reverse shell, we need to bind the " | ||
| + | < | ||
| + | ~ $ ./shserver | ||
| + | |||
| + | # (nothing will show up at first, until we run the next steps) | ||
| + | </ | ||
| + | |||
| + | Now, do as follows on your **host device** (the ones running adb to the Android system) | ||
| + | < | ||
| + | $ adb shell | ||
| + | devname:/ # cd / | ||
| + | devname:/ | ||
| + | # (now you can exit the adb shell. If " | ||
| + | </ | ||
| + | |||
| + | Return again to the Termux Android terminal and run the following things to have a neat and usable shell (capture ctrl+c, enable tab completion, use bash... etc) | ||
| + | < | ||
| + | # (something like this should show up in your Termux terminal after previous adb shell commands) | ||
| + | devname:/ | ||
| + | |||
| + | # Run the following commands: | ||
| + | devname:/ | ||
| + | .../ | ||
| + | # now ctrl+z the terminal (stop the job) | ||
| + | ~ $ stty raw -echo | ||
| + | ~ $ fg | ||
| + | # now terminal seems unusable, but press " | ||
| + | .../ | ||
| + | root | ||
| + | </ | ||
| + | |||
| + | To run the Termux apps as root on your new fancy root shell, you will need to add **usr/bin** of the Termux installation on your **PATH** variable on the shell. | ||
| + | <code bash> | ||
| + | $ export PATH=$PATH:/ | ||
| + | </ | ||
| + | |||
| + | Enjoy! | ||
