TWRP 3.4 Can install OZIP directly now! U don't have to follow This post anymore !! Thank u !!​
What is OZIP?? ​

OZIP file is an oZip Compressed Data. OZip is a simple compression solution in Python.
OZIP file is an Oppo Smartphone Firmware Update. An OZIP file is an encrypted firmware archive used to distribute updates to Oppo(/Realme) smartphones.​

Ozips are not directly installable from twrp or any other custom recovery*(though some device has the support). so for installing stock rom or revert to stock rom from custom rom u have to decrypt the ozip and make it a flashable zip for installing it via twrp or any other recovery.

Caution : I m not responsible if ur device got bricked during the flash or installation.A Full backup is extremely advised before tryng the stuff.

Needed Tools :
1 - A PC (Linux/WIndows) or Android WIth termux installed.
2 - Python 3+ installed
3 - Downloaded Ozip from https://www.realme.com/in/support/software-update
3 - Patience

Fow Windows User ::

*First Download Python3 From Here - https://www.python.org/downloads/
IMPORTANT Part for easy path solution!!!Mark the option!!!(follow the image)!!!


*Then Install it !!
U can also install python3 in ur system variables Manually!!! . <<<<If u don't know how!!! pls GOOGLE it!

* Now goto this link : https://github.com/bkerler/oppo_ozip_decrypt

*Click on Clone or download then click Download zip.

*Extract the files from the zip into the folder where u kept ur ROM(OZIP) in pc.
Remember : The two .py files from the zip must be in same folder with the ozip.

*now run cmd/Command Prompt as admin.

* Change directory by using Cd into the location of the files and ozip . ("Cd <location of the ozip>")

* Now type
"pip3 install pycryptodome" press enter
and then
"pip3 install docopt".press enter.

*After completing installing both. Type "python ozipdecrypt.py filename.ozip"
Example : python ozipdecrypt.py RMX1801EX_11_OTA_0260_all_mnxKIJM5sz0H.ozip

*U will see something like this
Found correct AES key: 1CA21E12271335AE33AB81B2A7B14622
Decrypting...

*Wait for the decryption. After completing decrypt u will get the zip file with same name in the same folder.

For linux and Termux ::
With due respect to the Author of the script!
Just follow the link https://github.com/bkerler/oppo_ozip_decrypt
and Read the README.md section below!!

Other Realme model User also can use this tricks to get zip file for their device.​

Please report if u get any error!!​
Thanks!!​

cant find decrypt.py

sir, the decrypt.py was not included in the oppo_ozip_decrypt-master.zip. I am following your instruction to "Remember : The two .py files from the zip must be in same folder with the ozip." can you send me the link? my oppo f9 hangs during bootup and stocks in logo. I badly need to fix this since i cannot go out to service shop coz we are in total lockdown due to covid19. your help would mean a lot. thanks brods.

the file downloaded from github link mentioned by the author above should contain these files:
.gitignore
README.md
ozipdecrypt.py
requirements.txt

if you have these files in your master zip downloaded from github then you are good to go .... make sure python is installed in your pc!!
and you will be using that "ozipdecrypt.py" for decrypting.

Big thanks to this guide. I'm in Win7 32bit. The cmd prompt with admin failed to install "pip3 install *****." so here is what I did. In the folder of the ROM and the ozipdecrypt, I used shift and left click(mouse), then chose "open command window here". then proceeded with the installation and decrypt instructions. Then I was able to achieve the zip file.
Hope this helps others with Win7 systems. Cheers
