tOot.toOt, Aug 5, 2017 : My device is rooted and currently running on Lineage Os 14.1 20170713 NIGHTLY Everything is great but m unable to install the latest 3 NIGHTLY updates. In TWRP the installation fails with message Error 7 , assert Failed : op3.verify modem . I searched for the issue in internet, And tried to install the UPDATES by Editing (updater_script) and removing assert phrase . And Installed the ZIP successfully but the Fingerprint scanner+home Key stopped working . Then i switched back to LINEAGE OS 14.1 20170713 NIGHTLY and everything works normal . So anyone plz suggest me the way to Flash the latest Update without getting error 7.
