[GUIDE] REALME 7 RMX2155 GLOBAL BOOTLOADER UNLOCK

Search This thread
UPDATE : Everthing's good now but I'm stuck right now.
How to boot in twrp using the buttons or adb command. Thanks !
You flash it, and then immediately reboot to recovery via the hardware buttons. Write "fastboot reboot". After, hold down Vol- and the power button until the realme logo shows up. Then, let go of power button, and keep Vol- held. Should get you in.

Thats the point, I can't do nothing because im stuck on the screen that says that the twrp has been succesfully sent to the phone.
I tried fastboot reboot recovery but the phone isnt recognized by the computer and I tried the buttons but it don't want to boot and when I relrease them, its just booting to system and I lose twrp again.

What am I doing wrong ?

Hold the power button on the fastboot screen. It'll take a while, but it'll turn of eventually. The,m with the power button still held, hold the Vol-. When the Realme bootscreen shows up, release the power button, but keep the Vol- held.

UPDATE : I managed to make everything works but now, I want to go back to Realme UI 2.0, how ?
Oops, I crossed the threads.

Anyway, this will work for you too.

You have to use SP Flash tool, use ONLY the download option, be careful to not use the other modes.

No, I just like flashed the provided rom again and formatted in stock recovery and it did it. (My phone became a rmx2155 again).

Issue no.1 : It seems like I'm stuck in Realme UI 1 that's why I'm searching for a way to update.

Note : OP need to change the version of adb plateform tools included in his zip file because it cause the phone to bootloop if we're using it to flash TWRP.

    hi, i got to step 10 and when i plug my phone i get error brom_cmd_send_da_fail and now i cant even restart my phone, please help
    Hold volume up + power button for a couple of seconds. It should force turn off your device. On your PC or laptop remove the libusb filters and install the mtk one again. Then try again with the brom.dat bypass

    i already used brom.bat and it disabled protection
    Okay,
    Inside sp flash tool try a different download agent (DA file)

    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!

    EXTRA SPECIAL THANKS TO:

    @albatron34000

    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;)

    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).
