[Realme 7 Guides, News, & Discussion] OrthodoxOxygen:
WELCOME, ALL.

After a very tiring process of swapping between ROMs and changing regions, APKs, et cetera, we have finally been able to perfect the method for unlocking the bootloader of the RMX2155! This is a detailed guide aimed to give you an easy time!​

FILES NEEDED:

So that you don't need to go through the irritating process of downloading everything, extracting the OFP, and going to sketchy places to try and find a stock ROM, you can now download everything from either one of the links below:

7.26 GB folder on MEGA

mega.nz

RMX2155UBL.zip | by OrthodoxOxygen for Realme 7

Download GApps, Roms, Kernels, Themes, Firmware, and more. Free file hosting for all Android developers.

Both links contain the same content: everything needed for this guide. It'll save you a lot of time.

----------------------------------------------------------------------------

PROCEDURE:

1. Download the .zip file from either of the links above, and then extract the files from inside.

2. Navigate to the "MTK Drivers" folder, extract the files, and then install them. For ".inf" files: You must right-click, and then select "Install" from the drop-down menu. You may have to disable a Windows setting for this to work, however, as they are unsigned drivers. You can learn how to do this here: https://www.howtogeek.com/167723/ho...8.1-so-that-you-can-install-unsigned-drivers/

3. Install Python if you haven't already. MAKE SURE TO ADD TO PATH.

4. Hold "shift" on your keyboard, and right-click on the Windows home-key. Click "Command Prompt (Admin)".

5. Type in the command "pip install pyusb pyserial json5", and then close your command prompt once it is done installing.

6. Extract the "Bypass Tools.zip" into a folder, and then navigate to the "Driver" folder within. Right-click on the file named "cdc-adm.inf" file, and select "Install". Wait for it to finish - though, it shouldn't take any longer than a second.

7. Install libUSB, and then open it. Power your phone off, and keep it that way. LibUSB should be called "Filter Wizard" in your start-menu. Right-click on it, and run it as an administrator. Have your RMX2155 and a trusty MTP cable on-hand. Click on "Install a device filter", then connect your Realme 7 with both volume-buttons pressed. Select and install the device that appears. It should have something like "MTK" in its name. Do this quickly, as it usually disappears after a few seconds. Once that is done: Unplug your phone.

8. Head to the folder with the bypass tools inside, and open "brom.bat". Connect your device with both volume buttons pressed. It should say something along the lines of: "Protection disabled" if it is successful. Disconnect your phone again.

9. Open the flash-tool folder, and launch the application inside. It is named: "flash_tool.exe". Select the scatter file inside the "OFP Contents" folder within the ROM folder, and un-check the following boxes: "Opposerver 2", "Special preload", "My custom", and "Cdt engineering".

10. Make sure that the box above where it lists all those files says: "Download only". This is very important. After you've verified that those boxes are without check-marks, and that the method is "Download only": Press the "Download" button at the top, connect your phone, and then press the volume-buttons. Once your phone is done flashing and a green check-mark is displayed: It will then boot. If it doesn't boot automatically, wait a few more seconds, and then hold the power key until it turns on. Give it some time.

11. Once it starts, and after you've gone through the main set-up process, you'll need to change your region to "Vietnam". This is a very important step to get your bootloader unlocked. For the sake of making this short: Follow the link. It will take you to a guide that should work for all OPPO devices. Please, read it carefully. From top to bottom. https://xdaforums.com/t/changing-a-...dated-instructions-now-working-again.4143415/

12. Move the Deep Test .APK file to your phone. Install it, and then open it. Submit your application, and wait. After: Just follow the directions given, and use ADB to unlock that bootloader. Use the following video to help you out if you don't already know how to unlock your bootloader with ADB! It also shows you how to flash a recovery, which will be useful if you wanna do that sorta stuff.

13. Success!

----------------------------------------------------------------------------

If you find that your phone won't connect through fastboot or SP Flash Tools after you've finished unlocking your bootloader, uninstall the LibUSB filter for your device (not the program), and then reinstall it.

For those of you wondering, YES, your phone can be flashed with GSIs, as it is a treble phone. However, you should download the "Treble Check" app off of the Playstore, as it supplies you with important information relating to which ROMs you can use with your device. IF YOU DO NOT MAKE SURE TO FLASH THE CORRECT GSI FILE TO YOUR PHONE, YOU MAY HARD-BRICK IT. Take a look at the guide below. Happy flashing!
