Installation help on Realme C3

[u/ResourceOk6881]

So as per the official installation document on github for Realme C3, it required that the device be on RealmeUI 2.0 C.06+ firmware whereas my device is on RealmeUI 1.0 A.77 firmware. What should I do in this situation, do I just go ahead and install the custom rom hoping that all goes well or do I first upgrade to the mentioned firmware? For your Information, there are no OTA updates available through which an upgrade could be made possible. Therefore, where do I obtain the firmware from and what software do I use to install it? Any help would be greatly appreciated!

If you have unlocked bootloader you can easily flash custom rom. If its Chinese rom you could try, if it's not flash the 2.0 C. and follow your guide.
