Late response, I just tested it right now and it works.
I've been trying to flash it through recovery but it seems its not working when flashed in recovery so I tried it again using spft and it did work.
I was just wondering, my internal storage didn't change but my app storage increased.
Everything was the same except for the app storage. I tried to check the partition details but it shows the same on stock.
I wonder where it was getting those additional storage.
I tried placing files in my internal storage and it doest store the same amount of data. Didn't test yet the app storage but I bet it can store up to its displayed storage value.
I'll be observing it for a while.
