So I was using CrDroid ROM (Android Pie) for my phone, rooted. Just now, I tried to update Magisk 18.1 through the Magisk Manager, and then I enabled Viper4Android Magisk module. After that, I tried to reboot the phone using an application from Play Store (can't remember which one), as my power button and my volume button are not working anymore right now. After that, my phone suddenly hard bricked, the screen turns off and there is only blue LED light appearing. Anyone has solution for my problem?
