For new users, please read about PerfectDynamics 2.0 Sound Optimizations first for new improvements with Fidelizer ROMs.
Hi. Sorry it took a long while. I tried to implement MangoOS mode since last few days and couldn’t get it to work. I managed to get to Mango option available but couldn’t change bootmode even with adb shell as root. I’ll settle without it for now.
-Based on firmware version Oreo 8.1 V1.03.036
–Yalp Store is added as Play Store’s alternative (I still keep Google services for those who want to install Play Store through other means)

-Revamped MangoPlayer UI with improved user experience
