[GUIDE] REALME 7 RMX2155 GLOBAL BOOTLOADER UNLOCK

Search This thread
I tried root on dotos and it was working fine, and I'm trying to root coloros cause its prettiest os I've ever seen, but imo it have to be rootable, no one there said that he has problem with rooting, and I can root it in pbrp but settings app doesnt working
I'm not too sure what to do in that case. You are using the boot.img for that exact version of ColorOS, correct? It cannot be any other.
 
Yes, I do everything, now I founded the boot.img from installed rom and did the same that before and it again get bootloop, I totally dont know what to do
I'm not too sure, then. Another person was contacting me with a similar issue, so, it seems that rooting a.87 might either be impossible at the moment, or that it might need a different process.
 
Is there any way to downgrade it to lower version?
Yep. Same thing, just with a different stock ROM. I think you can even upgrade to realmeUI 2.0 and root that, if you want. Here's a guide I found:

Hello, just tried to do this...Had to cancel the smart phone flash tool - There was an issue.

Now when I try to redownload everything I get an error:

Error Status_brom_cmd_startcmd_fail and then an error code - 0xC0060001
Hint: Please retry the operation
etc....

I have uninstalled and reinstalled the libusb filter.

Phone won't boot at the moment.

Help?

You need to use open LibUSB with admin, uninstall the filters, close it, then reopen with admin again, and install the filters once more. Then, run brom.bat. Should work.

OK, managed to get it sorted out...

Now I'm having another issue - When I try to unlock the bootloader, after I reboot my phone after utilizing the In-Depth Test.

I've been approved, and when I reboot, the phone resets into Fastboot, but when I run fastboot devices, my phone doesn't appear...Thoughts on that one?

You're supposed to use the volume buttons. Watch the video that was linked, and it should give you a general gist of what to do. Heads up: your phone is probably going to freeze after you unlock it. Don't worry; it happened to me and many others, too. Just wait a minute or two, and then hold down the power button until the phone restarts.

Yeah. I can't get to the point where I use the volume buttons.

I have watched the video multiple times...hah.

When I reboot from the in-depth test, my phone goes into fastboot, but it doesn't recognize any commands from cmd...

Unless I'm totally wrong, I need to send the fastboot unlock commands from cmd on my windows machine.

When I run fastboot devices, my phone doesn't appear even though it is in fastboot mode...so I can't run the next commands....fastboot unlock, which is where I use the volume buttons...I can't get to that point.

Try installing the filters for fastboot mode. Do you have any Windows settings on that might hinder the ability to detect the device?

You have to press both volume buttons AND power button

Was just the power buttons for me, I think. Maybe the guide differs depending on what update you're on? A lot of people have had issues I and many others haven't experienced. One of which would be when the bootloader unlock freezes when you select "yes": some, like myself, had it, while others didn't. Strange.

    Just re-do it - with the LibUSB bit before it. I had to do it a couple times myself, and it usually fixed the problem. Just give it a shot, please.
    thanks I'll try tommorow since it's already 11 pm for me I'll reply if it works

    No problem. Best of luck to you.
    it worked thanks so much

    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?

    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;)

    upload a87 instead. it work 100%​

    another person that i help upload file:

    Got it, thanks again to you and "Albatron34000" for the method
    Hope there will be brave souls to test this method
    It's just ridiculous that version 2155 still won't let you unlock the bootloader
    All that remains is to wait...
    Yes. According to the person who sent me these instructions: It does unlock the bootloader, which allows you to flash Magisk, TWRP, and ROMs. I haven't tried it myself, and this method has only recently become public due to my post - meaning that we need to wait for a brave soul to risk their Realme 7 for further development. Let's hope somebody tries this out soon. I'd be absolutely ecstatic if we could get one or two more people to confirm that it works.
