How can I update to PR1.1 without NSU(which removes some data) ? It gave me some message like "To update your device to this version of operating system you should use NSU" But I think I dont have to use NSU, do I? It seems like its related about my rootfs usage. How much free space does it need? I have 25~ megabytes.
you need over 45mb free for OTA so go to here to look at how to free up space, you might also have conflicting package so might need some more help after freeing up space http://wiki.maemo.org/Free_up_rootfs_space
Application files in /opt not being cleared by flashing firmware has been explained by fanoush.
Ok, so i flashed and restored everything, including my application list, which led me to install all my previous apps (not many, about 8-10) but I somehow missed your post about this 'bug' about not cleaning up previous app space (even though I read through this ENTIRE thread).
so is it worth uninstalling everything and cleaning up? and if so how do I do it?
is it safe to do this update? please can someone adviise me on this, as the previour minor update that came out a few days ago almost bricked my phone as it stopped at 1sec remaining with NSU, I had to then re-flash it using the flasher tool and the previous firmware. And now ive noticed my handset rebooted itself whilst i was using it the other day which never happened before.
So is it safe to do this update? anyone know why that happened with the previous update?
