i was checking this forum and noticed the test point method of rooting which allows to maintain the DRM keys. i do not purchase any songs or videos online neither do i use the trackID app of my phone. is there any other reason to save the DRM keys other than the ones mentioned?
i noticed a thread in another forum where someone was complaining about not being able to use camera after rooting without saving the DRM keys.
i would also like to know if there is any method of rooting the phone without unlocking the bootloader. the main reason i want to root my phone is to increase its internal memory and be able to use the USB OTG option in my phone which is locked.
i am trying this after expiry of the warranty period and seriously can't afford to brick my phone.
any help or answers will be much appreciated.
