before I begin with my post i would like to say thank you to all you guys you all are awesome especially hroark13 and mastercheif87 I appreciate all the time and work that both you do to improve the zte zmax for all of us and you both are by far the best devs i had ever installed custom ROMs from and the most forum active and i really appreciate you guys
i had rooted my phone and installed your twrp recovery months ago and flashed mastercheif87's boot switcher and boot restore and had applied kit Kat sd card fix while boot switched and applied link2sd and then restored boot and recently updated trwp and did a nandroid back up and all has been perfect until today
today my phone automatically downloaded the metro pcs system update (even tho I use atnt network sim card currently) and franticly in fear of it screwing up my zte zmax (like what recently happened to my lg g pad 7.0 lte screwing up from updating on its own and rebooting and getting stuck on the same twrp version as what's on my zte zmax and then rooted my girlfriends lg g pad installed trwp then flashed a backup then installed her backup in my serial numbers trwp back up folder then restored the back up and accidentally swiped yes to install su and got stuck in fastboot with no way out and had to buy another lg g pad) i had hurried up put zte zmax into airplane mode to block any further metropcs Ota control and rebooted into trwp recovery and i did a system wipe and flashed hroark13s cyanogen mod and all is well and the dreaded Ota update is long gone
after all that rambling lol lol derp lol now i get to the point of my post lol
i have 3 questions
my first question is where can I find the appropriate su chainfire zip to flash for this rom?
my su binaries won't update they fail and they also won't install choosing via trwp
my second question is is link2sd compatible with this rom?
my third question is can i use mastercheif87's boot switcher and boot restore on this rom to have write privileges?
