those devices have their stock recovery signed with testkey.how to start if not rooted yet?![]()
so if a zip package is signed with testkey too, and if the stock recovery is capable of zip sideloading,
the zip will pass the security check and install successfully by sideloading the zip via adb.
i have made a script tool that automates the sideloading process. 'gomdolight sideloader'.
