2. Select “Keep /system RO”. (Don’t swipe right or you may not be able to boot into the system if you failed to complete next steps. However, you can swipe right to allow modifications if you are confident that you can complete next steps.)
3. Go to “Wipe” menu of TWRP, and you will find “Format Data”. Press “Format Data” and type “yes” to continue.
4. Go to “Reboot” menu and Press “Recovery” to reboot TWRP.
5. Download the latest dm-verity and force encryption disabler zip on your computer.

– Option 2: ADB: Connect your phone with computer and run command “adb push /path/to/zip /sdcard/”.
– Option 3: External SD: Copy the zip to an external SD and then insert the card into your phone.
7. Go to “Install” menu of TWRP and flash the zip.
TWRP is initialized and fully functional at this stage. Now you can either reboot into system or root, flash custom ROMs via TWRP.
