Happy to share a workaround for root and successful DRM fix.
If you lose your drm key, that's okay, this fix will restore all function which depends on it (picture quality, super vivid mode, etc.....). There's nothing satisfying than using your phone at its full potential with your own custom. Spot the difference!!!!
1. Unlock bootloader
2. Flash boot.img (Patched to be compatible with the drmfix)
>>> fastboot flash boot boot.img
3. Flash recovery.img
>>> fastboot flash recovery recovery.img
4. Boot to recovery by holding vol - and power; then swipe to allow modification and Format data (mandatory)
5. Flash drmfix.zip
6. Flash Magisk 14.0
7. Boot to android, you're done!!!
Type *#*#7378423#*#* then >>Service info>>Configuration or >>Service tests>>Security to check if all your keys are active.
# For boot.img here!!!
# For recovery.img here!!!
# For drmfix This does the trick
