Custom rom to stock RUI3 recovery flashable zip file for Narzo 30 4G.

Package : Narzo 30 4G - F.19 latest

Steps
1. Flash Directly as usual custom rom using any custom recovery.
2. Wipe cache, dalvik, data, internal storage, metadata (if any)
3. Do Format data (type yes)
4. Reboot to system
5. Enjoy.

Caution:
Don't do reboot to recovery after flashing stock rom zip. You will end up frozen with realme logo and recovery mode at the bottom (in this case flash RUI3 supported custom recovery with fastboot commands or mtkclient and do format data and reboot to system)

Extra points:
1st boot will take 5 mins. So keep calm.
After a successful boot into system, stock recovery will work normally and updates too.
Even though the motive is to shift from a custom rom to stock without PC, you may keep a pc in hand to fix if anything went wrong.
This may work on Narzo 20 pro and 7 devices with minor bugs.
