This tutorial is for Minecraft Bedrock Edition worlds that have been imported to a Windows 10 copy of the game. It will work with XBox, Android, PS4, etc. worlds, but they must be first copied to a Windows installation.
Download the following two files.
- https://github.com/reedacartwright/mcberepair/releases/download/v0.2.0/mcberepair-0.2.0-win64.zip
- https://frippery.org/files/busybox/busybox64.exe
Place busybox64.exe in your minecraftWorlds directory. This is located at
%LOCALAPPDATA%\Packages\Microsoft.MinecraftUWP_8wekyb3d8bbwe\LocalState\games\com.mojang\minecraftWorlds.
Unzip mcberepair-0.2.0-win64.zip and place the contents of mcberepair-0.2.0-win64\bin
into the minecraftWorlds directory. (It's not strictly neccessary to place these files in minecraftWorlds directory,
but it makes things easier.)
Open a windows command prompt (cmd) and run the following commands.
cd %LOCALAPPDATA%\Packages\Microsoft.MinecraftUWP_8wekyb3d8bbwe\LocalState\games\com.mojang\minecraftWorlds
.\busybox64.exe sh
This will open up a Unix shell command line in your minecraftWorlds directory. rom here you canuse mcberepair and awk together to accomplish some cool things. The following set of commands will delete all the chunk data from the Nether and information about the location of Nether portal exits.
Note: replace t5BPXQwUAQA= with the directory for the world you want to edit.
./mcberepair.exe listkeys t5BPXQwUAQA= > list.tsv
awk '$5 == 1 {print $1}' list.tsv > netherkeys.txt
./mcberepair.exe rmkeys t5BPXQwUAQA= < netherkeys.txt
./mcberepair.exe rmkeys t5BPXQwUAQA= portals
