[GUIDE] How to Root Nokia 4.2 - Nokia 4.2 Guides, News, & Discussion

This guide will show you how to root your Nokia 4.2. This has been tested on TA-1157 and is working fine.
**Important** - If fastboot does not recognise your device In step 5, You need to download a driver. Here is the link: Download Driver (by Beebom)
Search up how to install custom driver and install it to the “Android” device.
Requirements:
Nokia 4.2 with unlocked bootloader
USB Cable
ADB/Fastboot.
Python
Your current ROM file
Internet.
Downloads:
ADB Installer (by Snoop05 on xda) : Download
Python : Download
Payload Dumper (vm03 on github): Download ( Click on code and select "download ZIP")
Magisk APK (on your phone) : Download APK ( Scroll down and you will find the APK file)
Code:
** I have only tested this on TA-1157. Other models may not work, but technically they should work.**
** Your warranty is now Void**
Step 1
Enable USB debugging on your phone. If you do not know how to do this, Search it up. It is easy.
Once that's enabled, Connect your phone to your PC/Laptop and open the command prompt (cmd) and type adb devices. It should show your device in the list.
Step 2
Locate the Python folder. To do this, simply type "python" in the start menu and click open file location. Then, Right click on "python.exe" and open properties. Then click open file location.
Once the folder opens, make sure to not close it.
Download the payload dumper.py which I have linked in the downloads section. Extract it and place the contents of the file in the Python folder.
Step 3
Download the ROM file. If you are using lineage OS on your Nokia 4.2, Download that file. If you are using the Stock rom, Download that. It should be a .zip file.
Extract the stuff from that file and take payload.bin and move it to the python folder.
Now, Open cmd in that directory by right clicking and opening cmd. Then, Type the following commands,
Code:
python -m pip install -r requirements.txt
then type,
Code:
python payload_dumper.py payload.bin
Once it is done extracting, Open the "output" folder. There you will find the "boot.img" file
Step 4
Use your USB cable or Google drive to transfer the "boot.img" to your phone. Once you have done that, Download the Magisk APK on your phone and install the app. (APK link in downloads section)
Once you have installed Magisk, open it and click "Install". Select the file from your phone and wait a few minutes for magisk to patch the "boot.img" file.
Once Magisk is finished patching, there will be a new file which magisk has created. Transfer the patched file to your computer via the USB cable or Google drive and make sure to rename it as "magisk_patched.img"
Step 5
You are almost done! Open CMD in the folder where you saved the "magisk_patched.img" and type
Code:
adb reboot bootloader
then type
Code:
fastboot flash boot magisk_patched.img
Once done, Reboot your phone and Voila! Your phone is now rooted. Make sure to open the magisk app and check it.

Personally, I do not recommend Kingroot as it is not very reliable and safe. Instead, you can follow this guide or follow other guides on youtube.
