[GUIDE] REALME 7 RMX2155 GLOBAL BOOTLOADER UNLOCK

Search This thread
Anyone knows how to fix no WiFi connection? I unlocked my bootloader RMX2151 - A10 using only in-depth tool apk, after flashed BlissOS.
BlissOS was kinda buggy for me. Caused my phone to crash. I recommend doing a full wipe of all partitions (excluding external storage and internal storage [you can wipe intyernal if you want, but not recommended if you don't have an SD Card]), and then flashing a different ROM. CrDroid, EvolutionX, and Nusantara are pretty good.

Thanks, it's very strange, I flashed other ROM (evolution, OctaviOS), and it refuses to boot normally, it redirects me either to fastboot or recovery, I flashed the vbmeta image, Magisk but nothing.

Trying to flash the ROM through SP Flash tool gave error 00a0001 and installing the stock recovery and flashing an update for 2151 didn't work, so by now I'm bricked. I guess my device model switched to 2155, if I can get a recovery update ROM for 2155, maybe can fix it.

Wait. Was your model originally an RMX2151, or originally an RMX2155?

If you followed this guide, you absolutely shouldn't have. This method is strictly for the RMX2155, as stated in the title. If you flashed the ROM provided, you should try and flash a different one immediately. The one uploaded has been modified so that it may work for the RMX2155. Try one from here:

I unlocked my device using just the apk, I didn't use this guide but probably BlissOS did break my WiFi, from there flashed LegionOS, and I couldn't boot to OS anymore.

Then I tried 3 ozip updates, no luck and finally tried your ROM. I can't go manually to fastboot, in case you know some trick, the normal vol up + PWR button doesn't work. I will try from the link and update, thanks.

Your best bet is to flash a stock ROM, and then go from there. Sounds like it needs a total reset, unfortunately.

Did you make sure to follow each and every step exactly as described? No shortcuts?

If so, then try (all with admin privileges) uninstalling LibUSB drivers, reinstalling them, and then re-running brom.bat. Remember, do that all with admin privileges. Let me know if it works.

    Hi, can i unlock bootloader using this guide?

    RMX2155_11_C.13
    Yes you can. I was also on the same version! Good luck! Your phone will be downgraded to a asian realmeUI 1.0, then your sales region will be changed to a country in Asia (it needs to be the one in the guide) and then you just download an app so you can enter fastboot and then unlock the bootloader.

    Everything worked without issues for me. If your phone doesn't show up in fastboot, manually go to device manager and install the android ADB driver (I can help you if you need).

    Should work fine but I recommend Windows 10. You need a functional WiFi card since the software that changes your sales region needs you to disable Ethernet so it can connect to the phone.

    There's only one way to change in the settings
    You haven't changed the region correctly then. You see, you're currently changing your geolocation for currencies and such. But the in-depth test app will check your sales region.

    To change your devices sales region, follow this link. You will need a Windows PC or laptop with WiFi functionality:

    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!

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

    I AM NOT LIABLE FOR ANY DAMAGES, BRICKED PHONES, OR ANYTHING ELSE THAT HAPPENS. IT IS YOUR CHOICE TO FOLLOW THIS GUIDE, AND THE CONSEQUENCES ARE YOUR RESPONSIBILITY.

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


    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:



    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://forum.xda-developers.com/t/...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!

    Working with you has been great!

    Many, many thanks for this part!

    “I had issue with ‘fastboot flashing unlock’. on option press volume up to unlock it did nothing, after 5 minutes i pressed volume down, yet when i rebooted it was unlocked. just sharing this for everyone here”

    The same happened to me and I was already going nuts! This really helped! Thank you!

    Also, many, many thanks to OrthodoxOxygen for this guide!

    May I suggest that you update your guide by adding at the very end something like: “If, after executing ‘fastboot flashing unlock’, pressing Vol Up does not work, press Vol Down and the phone should be unlocked.”

    Do you think roms made for the RMX2151 will work? PixelPlus for example
    Yes it sure does!
    I'm currently using the Pixel plus rom
    Most (if not all) RMX2151 roms will work;)
