A simple noob-friendly script that strips the system of the Evenwell apps from your Nokia.

Nokia-Debloater

A simple noob-friendly script that debloats your phone from the evenwell apps and soon, Google Apps.

Author's Note - I tried adding apps to debloat from the Chinese ROM, Unfortunately they come back into the system after debloating. Hence, There is no way to remove these apps other than rooting. Please do not try using the Global ROM's script on Chinese devices, You could potentially brick your phone and your only option to recover will be factory resetting.

For the Linux/Mac Version of this script, Head to - https://github.com/Sid127/Nokia-Debloater/releases

What is evenwell and why should I care?

Evenwell/FiH is chinese company. Specifically, They are a subsidary of the massive Foxxconn group that manufactures consumer electronics for sale around the world. This Evewell group were a business partner of Nokia/HMD and they were responsible for manufacturing and building the software on these phones. On the surface, The first and second generation Nokia devices have no bloat, But when you go digging deeper into settings and the system, You will encounter these evenwell apps.

What do these apps do?

These apps are supposedly to maintain system stability and protect battery among various other services/features. There are also telemetry apps that send data to the chinese. This is the reason this script has been created.

Nokia has supposedly stopped using the evenwell services/apps, Why would you uninstall them?

Simple, Because -

1. I do not want any dead app that previously had an history of snooping in my system.
2. They are not supposed to be there in the first place.

Okay, You've convinced me. What do I need?

1. A Nokia phone
2. ADB/Platform tools from Google which you can get from here - https://developer.android.com/studio/releases/platform-tools
3. The Debloater script
4. Windows 10, If you're on Windows 7 or below download Adb/Fastboot tools version v28.0.01 or below.

2. Download "debloat.sh" from the releases section
3. Open a terminal in the location where you downloaded the debloater. For example, if your file is downloaded in "/home/user/downloads", open a terminal there, or open a regular terminal and run the command "cd /home/user/downloads/"
