I found related threads: http://wiki.maemo.org/Tabletsdev https://talk.maemo.org/showthread.php?t=90052 https://talk.maemo.org/showthread.php?t=96584 PR 1.3.1 cannot be downloaded from https://www.fladnag.net/downloads/telephone/n900/ and https://web.archive.org/web/20131117...ev/nokia_N900/ so I think I will download PR 1.3 and install CSSU after that. Do you know what the difference is between the global and UK firmware version? Can a global firmware version be installed on a UK device?
