My phone has the "Monkey Test" virus and there is solution in here, but when I try to execute this command:
chattr -iaA providerCertificate.apk
I receive the error "chattr : not found".
I found a solution here, which is to install e2fsprogs, but I don't know how to install it using ADB. How can i install it?
chattrbinary works fine. Follow that XDA thread carefully. – Firelord Sep 29 '15 at 16:22
