First of I already done my research about how to root without TWRP/Custom Recovery since my phone brand is new which is RAVOZ.
Now i finally found a solution which is to root without TWRP/CR but there is a problem.
On MAGISK you can root your phone without it, but it needs a ‘Stock boot image‘ but i can't find it anywhere on website. Please somebody help me to root my phone.
Phone Model: RAVOZ Z8 Android Ver: 9
