Kingo nt kingroot is how i rooted the concord 2. n was the first to do so! go on concord 2 thread n follow my directions.... since u have root by way of kingroot. Make sure its nt kingroor! Anyway download an apk called rashr off playstore.... make sure hroark13 CWM img. for concord 2 is on external sd card n use rashr to flash image.. As Flashify will give you a no SU error, then either keypress combo into recovery or use a rebooter apk off playstore to reboot into recovery then make a nandroid bakup.... I advise having jollyxp3r!m3nt rom on sd aswell no gapps needed its stock! flash rom then add su zip v 2.82 most recent update zip after rom.... so rom add su zip Flash! Remember to wipe EVERYTHING BUT UR EXT SD! Reboot from recovery into recovery then flash ROM & SU zip then wipe cache and delvic cache AND ENJOY! I took a risk and kingo allowed me to kick it out of the way for SuperSU by chainfire off playstore off rip! BUT THAT WAS KINGO NOT KING-ROOT! just use rashr to flash hroark13 cwm.img. You will have to extract cwm img. from zip file... cwm is on concord 2 thread by Hroark13 and its on his pc root n recovery method just grab his img. n thank him! AND BCRICHSTER! for the cool stock deodeced and mostly debloated stock rooted rom with other cool flavor like the AWSOME Jolly Roger boot image! If u have issues get ahold of me on concord 2 thread! see u there! this is The-Truth my instuctions are on thread!
