ROOT APPS: ADBRoot & Telnetd for KaiOS / Nokia 8110 4G, 2720 Flip, 800 Tough and other KaiOS Devices


Currently it is easier and safer to obtain
root privileges on KaiOS devices using our apps. Like all apps for Firefox OS and KaiOS they
are written in HTML, JavaScript and CSS. They can all be installed safely and do not
result in the loss of official updates, even if the user can use them precisely to make
profound changes that can lead to the loss of the warranty and the aforementioned updates. Use at your own risk! They are all installable using OmniSD or WebIDE,
Kdeploy, Make-kaios-install or patching them directly in an image of the data partition
to flash in EDL mode. Here are the details, starting from the first,
in chronological order: Telnetd,
was the first root application for Nokia 8110 4G.
Written by Speeduploop, it exploits the “telnet” protocol in offline mode, so without internet
connection, like all other applications for the root.
Once started with the phone in debug mode, just press the central button to activate
it in the background. This will start the server.
Once the device is connected to the PC using a USB cable it will be possible to start the
necessary permissions from “adb shell” by typing the following command:
busybox telnet localhost the app will use engmode-extension and in
this way it will be possible to run a shell with root privileges using busybox.
To deactivate the app, press the center button again.
The weight of the installation is about 154 kilobytes. ADBroot,
always written by Speeduploop, it works like Telnetd, but with the only difference that
inside it contains the binary file “ADBD”, which increases the weight to around 435 kilobytes,
making the app more autonomous! In fact with this app it is possible to enable
the ADBD daemon directly and without having to type “busybox” from “adb shell”.
ADBD is required to communicate with all the extensions and binaries necessary to operate
as root on the device. On some devices ADBD is not present, and this
app with the necessary extensions implemented by the user allows to perform the same operations
available on the Nokia 8110 4G. ADBroot is the best root app for the bananaphone! Thanks to this app it was possible to open
the way for the development of another project: Wallace, which I will show you in the next
video. See you later…
