So I have a rather odd issue. Updated to Oreo which is fine. Then followed whats in this guide https://discussions.citrix.com/topic...-application/. All went fine apps all seem to work great root worked better than ever even SUhide works great. Only odd thing I have now is I play a Marvel Contest of Champions on my phone the app launches then says "Your Device is out of storage space. Please clear some space and try again later." Which makes no sense I have 65 GB of free space. So I did some trial and error and found out that the error only happens after flashing SuperSU I tried it both with 2.82 SR3 and SR2. Just uninstalling SuperSU doesn't correct the issue either I have to boot to TWRP wipe system and rerun the update of Andriod to Oreo from ADB and the game will launch fine. But if I again try to flash SuperSU it pops the same error after reboot. The phone is Pixel XL running 8.0.0 Patch Level is 8/5/17 Build Number is OPR6.170623.012. The game is the only thing that doesn't seem to work it's very odd. I also tried letting the phone update 8.0.0/OPR3.170623.007 which is Patch level 9/5/17 I believe and it was still the same issue after flashing SuperSU. I would post logs but I am honestly not sure which logs to post for this kind of issue. I also tried reflashing SuperSU from FlashFire on the build OPR6.170623.012 still the same issue. Any help would be appreciated.
Also instead of wiping system and reinstalling Android see what happens if you just restore the kernel to stock. You should have a backup image of the stock kernel at /data/stock_boot_<sha1 hash of boot image>.img.gz
The hash is of the image file after you extract it.
Or just take a backup before applying Supersu.
Take a backup of the boot partition before restoring stock then to get root back just restore the backup.
This works because most of what supersu needs to do in order to work takes place in the kernel patches it applies. The support files will still be on the data partition, they just won't do anything.
