MR2Tachiyomi

A simple tool that takes MangaRocks database and outputs a file that you can import using the backup restore tool in Tachiyomi.

Only supports Android version of MangaRock.

Currently only supports the sources MangaRock, MangaEden, MangaReader.

Usage

Currently the steps are very technical and might be complicated for the typical user, be aware!

Pre-requisites:

• Java 8
• MR2Tachiyomi Application Jar
• Tachiyomi and extensions (Download in-app)

Method 1: Using mangarock.db (Rooted devices only)

1. Find and copy the mangarock.db file on your android device to your PC

   • File is located in the directory root:/data/data/com.notabasement.mangarock.android.lotus/databases

2. Run MR2Tachiyomi Application Jar (Double click the jar) and open the copied mangarock.db file.
   Click Run and choose a save location for the output file (Read below for more details).

Optionally for those wanting to use the command line instead of GUI:

java -jar mr2tachiyomi.jar -i /path/to/mangarock.db -o /path/to/output.json

3. After running there will be a new file created which can be imported into Tachiyomi using the backup restore feature in the settings menu. Note: MangaRock or other relevant Tachiyomi source extensions must be installed, or else the import will fail.

Method 2: Using Helium Backup (Both Non-Rooted or Rooted devices)

1. Backup MangaRock using Helium Backup

2. Copy the file
   sdcard:/carbon/com.notabasement.mangarock.android.lotus/com.notabasement.mangarock.android.lotus.ab
   to your pc

3. Run MR2Tachiyomi Application Jar (Double click the jar) and open the copied com.notabasement.mangarock.android.lotus.ab file.
   Click Run and choose a save location for the output file (Read below for more details).

Optionally for those wanting to use the command line instead of GUI:

java -jar mr2tachiyomi.jar -i /path/to/androidbackup.ab -o /path/to/output.json

4. After running there will be a new file created which can be imported into Tachiyomi using the backup restore feature in the settings menu. Note: MangaRock or other relevant Tachiyomi source extensions must be installed, or else the import will fail.

File output

Change the output file name to get the desired format:

• Tachiyomi Backup Json -> output.json
• CSV List File -> output.csv or output.txt

Troubleshooting

Having problems with Helium on PC?

Try using the Chromium extension instead

I'm getting some kind of SQLite error!

The tool decodes a mangarock.db file out of the backup ab file, if it's 0kb in size then you have a bad backup.
