Hello, I have ResurrectionRemix installed and I have been giving serious problems so I decided to downgrade to the original version of manufactures meaning stock. Can someone link me to a good tutorial where I can find the links for download the original version, which installs Motorola, ie the 4.4.4 and that the links work? I've been looking for this and I can't find a good one all have death links and so on and I am afraid to brick my phone, any advice?
