I started the process but am a little concerned about the OEM Unlock. On my phone it claims that it will factory reset upon reboot. This is the international version. It has an incredibly annoying turn on and turn off sound that needs to be changed. I had an international phone a few years ago that was rooted when i got it. I was able change the on/off sounds and hope to be able to do the same with this J8. Can I still root without the OEM Unlock?
