^ it's in the storage folder and yes you can safely delete that it is just a leftover folder when you install TWRP. I guess the BDO app scans for that folder when it launches. Good luck!
its so odd that only BDO does that. kaya pala kahit nag factory reset na ako at unrooted na ang lumalabas sa root checker ayaw parin ng BDO app gumana. thanks for this. been wondering why i cannot use the BDO app
