I am trying to change my device encryption password by opening a terminal in TWRP and typing vdc changepw default_password 1234 and it's giving me vdc: inaccessible or not found.
Is there something wrong with my approach or is the issue with the phone?
vdcwon't work in recovery. It's a dynamic binary in/system/binwhich links to libraries in/system/lib. Usually this doesn't happen automatically in recovery mode. But even if you manage to do so,vdcis just a small wrapper to communicate with the actual bigger servicevold. But in recovery mode OS and hence its services are not running. So many of Android's commamdline tools don't work in revovery mode, includingamandpm. – Irfan Latif Sep 18 '20 at 06:00
