The su language changing process is driving me up the wall. I tried to update SuperSU's binary over mobile data & wifi, both failed miserably. Not sure what's the problem. Just to be clear, the hp has proper root. I've installed root checker and link2sd, both were asked for permissions from chinese su, and thanks to ntuser88 & bluehaze, at least I know which one means Allow now hehe. But that's the thing, I wish I can live with the su being in chinese, padahal that's the main problem.
With Superuser,
installed successfully
binary updated
but failed to gain root xs (I wish i know where to add or authenticate it in chinese su, major language prob as u can see)
With SuperSU
installed successfully
the second i launch the app, it will prompt me to update the binary, gave me the option of CWM or Normal, if I hit normal, the update wont go thru and stated failed. If i hit CWM, nothing happens. Like yall suggested, go to settings and choose install SuperSU into system, but like I said, the moment I launch the app, it goes straight asking for an update, didnt manage to click anything else. I checked SuperSU's page in Google Play, many users are facing the same prob as mine. Failed to update the binary. So yeah sorry if its tldr.
Did u manage to change the language to english? If yes, I might just give mgyun another try. Huih.
You need to give permission to the SuperSu from your Chinese SuperUser. Then hit update and then go settings and install SuperSU into the system.
