I have a Samsung Galaxy note 10.1 2014 edition that is my love. It is my daily driver too. I recently upgraded to lollipop, but faced issues with graphics quality being dropped due to some memory leaks or whatever (maybe it was developers making excuses cos they can't do anything)
I can't play games nicely cos the graphics are terrible. Samsung released an app called Game tuner, but it is only for the s6 and above. (Thank you for abandoning us Samsung). I decided to flash twrp recovery and CyanogenMod 13, so I could side load that app and the service it requires to run (the service is restricted to marshmallow)
According to their website, I can use Heimdall suite to do the flashing. I would love a guide please, step by step. They mentioned that you don't need to root in order to flash custom ROMs. Is this true?
But yeah, this is a $700 device when I bought it couple of years ago...warranty is expired. And I don't want to mess up this. Thanks!
Edit: My device is the Sm-P605 and the nightly release for my device has code: lt03lte
I know there are risks involved and want to minimise them. I would prefer not to root but just flash twrp recovery and CyanogenMod 13.
