So I recently acquired an S4 and Im looking to flash CM. Im been looking through the forums for days to see how to do it properly, install custom recovery, root, i.e, all that good stuff. Unforutately all the threads are mixed in now and its quite messy, not like before where each carrier had their own dedicated section. I keep looking and I cant find what Im looking for. Im on the L720T phone, running the OK3 update which is the latest update. From what ive been able to gather there no root available for that update which means Id probably have to downgrade to a previous version of the firmware, Im not finding much with Odin and stock tar files. (can always use traingle away to get rid of the counter). or couldnt i downgrade using the sammobile site with the software from it. then root it once im on a firmware version that rootable. Before Im root it should proably install a custom recovery first to be able to backup my phone up. ive read about knox but should i really care if i trip the know flag? seems that cant be reset but i never needed my warranty anyway. whats the best way to go about doing this? Once im rooted and have custom recovery, ill be able to to the rest myself, just dont dont want to bork my new phone up. recovery and then root if possible.
