Just bought a secondhand xm 14, local set, unable to setup singpass due to 83-T991 error, anyone got suggestions?
Singpass helpdesk says: Thank you for contacting Singpass Support.
You have encountered error T991 when setting up your Singpass app due to an incompatible secure key storage module. This is because your device may be running an unrecognized version of Android, may have an unlocked bootloader, or may not have been certified by the manufacturer. As Singpass can be used to access personal data, security is prioritized to protect Singpass users. The secure key storage module is a minimum-security requirement for the Singpass app to work.
