oh yea, i forgot about sparse img tools, glad you found it. looks like its working for you, hopefully it doesnt brick your phone
LOL. to rephrase this: almost every problem you can encounter has a ready-made, open-source solution in GNU/Linux that you can install from a free library by a single copy/paste. dependency management CAN be a nightmare, but its generally much LESS of a nightmare on GNU/Linux platforms like debian and fedora.
haha, i truly cannot tell if youre joking. please do not tell me, it would only spoil the mystery.
like i said, sailfish is largely based on mer. mer is an open-source mobile-friendly middleware platform that evolved out of MeeGo (Nokia N9), which in turn evolved out of Maemo (Nokia N900) and Moblin, etc etc.
sailfish = mer + proprietaryGUI
btw, you can change nemo to anything you like in that script. with this script, the username can by anything, EXCEPT it cannot be more than 11 characters, because the script does not touch the filesystem metadata. (another method for editing the images could allow this)
also, and for the same reason, make sure that you keep any âextraâ whitespace for usernames less than 11 characters in lines #54
and #61
so that the old and new versions of that file have the same number of bytes.
