How do I undo all the patches/restore firmware?

readingtolearn · 12-24-2019, 02:45 AM

I installed an adblock patch using KoboRoot.tgz, and it broke the fonts for my language. There is no uninstall option like the other patches, so I tried another koboroot.tgz with a bare minimum /etc/hosts file, but the fonts are still missing, although when I go to detectadblock.com, it tells me I'm not blocking any ads. I tried factory reset, and downloading the firmware manually to .kobo. Both times, the kobo reset everything, but the font is still missing, and I see the default settings for the miniclock addon. How do I completely restore the clara hd so that all the patches are reverted?

Can I see the KoboRoot.tgz used for the adblock? Also, a full manual reset should do it (see the Kobo help, or use the reset from developer options).

If this is the adblock you installed, try doing a manual install of the 4.19.x firmware.

Thank you, that is the Adblock I used. After I manually reinstalled firmware and the font, it’s working fine now.
