Hi,
I have my hands on an old Lenovo IP Duet 5 tabled and keyboard. The device was used in software development and after hard-reset the boot menu states the following
"This firmware is developer-signed. MP-signed recovery images will not work"
The device itself is still in good condition, with battery holding nicely (4-5 hours of IPTV on Wi-Fi drained around 40% of the battery). The main problem is the old software, being unable to update most of the apps or install new ones, or if something installs there is a big chance it won't work.

Is it possible and how hard it is to reflash new firmware and newer version of ChromeOS, and how hard it is to do it? Are there any guides on doing it?

is your firmware writable ? if so, you should be able to boot a recovery image and have it update the firmware to MP key signed.
