Mijzelf:

After installing lede-17.01.0-rc1-r3042-ec095b5-lantiq-xrx200-P2812HNUF1-squashfs-sysupgrade.bin on top of Chaos-Calmer on my P-2812HNU-F1, it kept it's old config, although I didn't specify that
sysupgrade /tmp/lede.bin

After activating fail-safe I tried to use firstboot to drop the config, but it failed:
root@(none):~# firstboot
This will erase all settings and remove any installed packages. Are you sure? [N/y]
y
/dev/ubi0_1 is not mounted
/dev/ubi0_1 will be erased on next mount
writing /dev/ubi0_1 failed: Operation not permitted
After rebooting it had kept it's config.

Worked around it with
root@(none):~# mount_root
switching to ubifs overlay
root@(none):/rom/root# firstboot
This will erase all settings and remove any installed packages. Are you sure? [N/y]
y
/dev/ubi0_1 is mounted as /overlay, only erasing files

techsolx:

Same issue, a few differences:

Fully functional Chaos Calmer 15.05.1 on a Linksys 1900v2. Update to lede-17.01.4-mvebu-linksys-wrt1900acv2-squashfs-factory.img

Unable to run firstboot as above.
Work around as noted worked.

This appears to impact multiple devices -- the overlay is NOT erased on next mount, as indicated

Seen on IPQ4019-based Linksys EA8300 (WIP) -- master, Linux 4.19

mpa:

I can confirm the problem with firstboot for the BT Home Hub 5A and a current OpenWrt snapshot (r9851-d1739c6c9a).

jffs2reset was made for a different filesystem. Please try this instead:
ubiupdatevol /dev/ubi0_2 -t
To find the right ubi volume to wipe out:
grep rootfs_data /sys/devices/virtual/ubi/ubi0/*/name

jeffsf:

The core of the problem here is that writing a JFFS2 mark to a UBIFS volume doesn't make any sense.
