Why not just blow it all away, dd /dev/urandom over it and then mkfs.ext3?

In my opinion, formatting rootfs isn't worth it and probably won't work anyway, because the partition is marked as in use by ubifs - at least, I couldn't get any of nandwrite, ubirmvol, ubimkvol to do anything. Also, if we completely nuke rootfs and then the battery dies or we reboot by accident then we're hosed, as BackupMenu itself wouldn't load (until such a time as Fabry hopefully gets a u-boot version to work - I'd love to try myself, but I'm snowed under at the moment). Of course, the ideal solution would be to get BackupMenu to use fiasco-flasher or similar instead, as this would do exactly what flasher-3.5 does with the -r argument, but I'm not sure it's possible to do this as my previous attempts have failed.

If it does do it drom scratch it's basically flashing and we use known-clean FS. Fresh format and unpack files. Not that we have many an instance where that matters.

If you look at Robbiethe1st code, rootfs gets wiped out before restoring it, through rm -rf *, so it's as risky as formatting.
I didn't think rootfs is mounted and cannot be unmounted, though, so maybe better give up on this issue.

It's not that it's mounted (BackupMenu itself actually mounts it to /tmp/rootfs I believe), but rather that the ubi module has already marked the rootfs partition of the NAND as being in use and therefore refuses to allow nandwrite or any of the ubiformat/mkvol/rmvol/updatevol to work. I didn't fully test the flasher route, but I couldn't get it to do much of anything with my rootfs zlib image, presumably it's hitting the same problem with the ubi layer somewhere?

@debernardis:
Sorry for not reading the topic in so long. I'll take a look at your mod and add it.

@Tigerite:
I /heard/ that someone was able to flash a converted BM image via one of those ubufs tools, so it may be possible. Still, the ubifs doesn't fail to the point of needing a format usually - Optfs does, however, so I'm going to be adding the above patch soon.

hello robbie. i would like to ask u one thing. like my friend wants my applications and overclocking settings etc. i told him that i could give him it through backuping up my phone and then transferring the 2 files in his phone and then he can restore it. can u please tell me out of the 2 files, which one is for settings and applications etc? because he doesnt need my contacts and conversations etc. and if he restores it than his current conversations and applications are gonna stay right? its not gonna get deleted right?

Um. Use the built-in Backup tool for that.

BackupMenu creates a filesystem snapshot, which is not what you want.

i actually restored my phone with this after flash. the existing backup manager doesnt backup all settings, command, queenbeecon widgets, overclocking, linux enhanced kernel ETC.

so which files out of the two are just for apps and settings?
