Support of Glo and newer models is slightly better than in former versions. As always you will have to edit the patch files in accordance with your needs and your device.

Usage:

• unpack the attached archive on your pc
  
  Spoiler:

  The path should not be too long (cf. this post), and should not contain "&".
• edit the files libnickel.so.1.0.0.txt and nickel.txt as you see fit
• copy kobo-update-3.12.0.zip into the folder 3.12.0_source
  
  Spoiler:

  Alternatively you can

  • copy KoboRoot.tgz (extracted from kobo-update-3.12.0.zip) into 3.g12.0_source
  • or copy KoboRoot.tar (extracted from KoboRoot.tgz) into 3.12.0_source
  • or copy libnickel.so.1.0.0 and nickel (extracted from KoboRoot.tar) into 3.12.0_source

  You can find the download link of kobo-update-3.12.0.zip here.
  
• double click on 3.12.0.bat
  
  Spoiler:

  If you do not want to compress the resulting patched files into KoboRoot.tgz, use 3.12.0_no_packing.bat instead. I now prefer to put the files with the restore option of KSM to their location.
• copy the newly created KoboRoot.tgz, which you will find in the folder3.12.0_target, to the .kobo folder on your device.
