For this purpose is there app /usr/lib/qt5/plugins/devicelock/encpartition

--is-set lockcode
--check-code <oldcode>
--clear-code <oldcode>
--is-clear-device-set ???
--unset-clear-device ???
--imei <something>
--clear-code <oldcode>
--set-code <oldcode> <newcode>
--set-config-key ???
--developermode ????
--clear-device <oldcode>
True/False are returned via exit code where 0 - success, 1 - fail
else as standard output.

Configuration is stored at directory /usr/share/lipstick/devicelock/ and encrypted/hash key is stored at /usr/share/lipstick/devicelock/.devicelock.enc, quite interesting are stored texts at binary file encpartition:
41414141, 42424241, 123456789012345 and /dev/block/platform/msm_sdcc.1/by-name/QOTP . More on

Unfortunately still don't know how reset device lock without sending to repair facility or brute-force.

Test all numbers with length 5 takes less than 3 hours on the phone with utilizing 20% of CPU.
Could you please explain how I use the posted app (zip file)?

The phone would not come back to you anyway, so maybe t makes harder for theft to sell it, but eventually he will, but in cost of making it harder for users, by locking themselves out.

Let's compare it with gmail locking you out forever till you contact them for 5 mistakes. It sounds great, but it's not that practical, so it makes only pain for users.

There are other options that can be used i think.

At the risk of digging out an insanely old thread:
Simply removing /usr/share/lipstick/devicelock/.devicelock.enc and then running

/usr/lib/qt5/plugins/devicelock/encpartition --set-code
will reset the code (or probably just using the settings-app will work too).

You can remove the file using any "As Root" file explorer from openrepos.

Thank you so much, I never found this information, which enabled me to "upgrade" my testing phone to a fully capable backup phone, again.
For more than two years I lived with the awkward situation to have full control over the device (as root), but being unable to set the lock-code (fortunately "automatic locking" was unset, so the device became my testing phone).
