How To Guide [EU model] Unlock bootloader of European model
- Thread starter Rapper_skull
- Start date
OK, I changed adb, has this output, but phone rebooting and productname doesn't changing.
RMX3301_11_A.16. I see some error with magisk/busybox. Idk if it's important in this case.
Yes, it is. Have you tried to reboot the phone and retry?
EDIT: Probably it's the same problem as above. Update to the latest adb version.
I attached a new version of the script to the OP. This new versions shows more info do better debug problems, and waits 30 seconds before getting the model again to show if everything worked.
It's better if you ask these questions in a more relevant thread. For now there's no custom rom available for the GT2 Pro, and for SafetyNet you can use https://github.com/kdrag0n/safetynet-fix/
Yes, the app should remember that you're approved. Even if it doesn't, you can just repeat the procedure.
If you flash another ROM on the Chinese model, you already have an unlocked bootloader. I don't see any reason to follow this procedure.
Can anyone say if by unlocking the bootloader (and rooting?) they got to fix the annoying bugs in the system? For example, how the notifications disappear on the lockscreen (but stay in general) once the device has been unlocked? Or the late notifications for almost every app. Stuff like that. Or
Does this mean that you could theoretically unlock any Realme phone just by changing the model name?
For example, the GT Neo3?
For example, the GT Neo3?

Theoretically, yes. If you have a GT 3 Neo, can you tell me what kernel version you're running?
Unlocking the bootloader (and rooting) will not magically solve any bug. That is a problem with the software that only Realme can fix. However, when the kernel sources will be released, maybe someone will create a custom ROM that fixes the bugs and adds new functionalities.
Well I thought maybe there are some root specific fixes that could be applied, but I guess that's not the case. The software is the only thing keeping me from actually buying the phone (had one from amazon and sent it back).

Yes, that's unfortunate. I would love to see a custom ROM for the phone.1 -
8As you may know, at the time of writing it's not possible to unlock the bootloader of the European model. Fortunately there's a workaround. To know how it works, scroll to the end of the post.
First of all, this is only for the European RMX3301, but you can try on any other global model that doesn't allow the unlocking of the bootloader. I'm not talking about temporary errors, but of the infamous This phone model does not support deep testing error message.
Before starting I would like to thank polygraphene for their implementation of the Dirty Pipe vulnerability on Android. Without that, this would not have been possible.
Requirements:
- The phone with a decent charge. Do not attempt this procedure with the phone at 10% and then cry if something goes wrong
- A compatible build, read below
- A Windows or Linux PC with adb and fastboot drivers installed
Check if your build is compatible:
- Go to Settings -> About device -> Version and check Build number:
- If your build is between RMX3301_11_A.14 and RMX3301_11_A.17, go to the procedure below
- If your build is lower than RMX3301_11_A.14, or higher than RMX3301_11_A.17, install this OTA package to downgrade (or upgrade) to RMX3301_11_A.14
Procedure:
- Make sure under Developer options you have OEM unlocking and USB debugging enabled
- Download and extract the attached gt2pro_eu_unlock_dirtypipe_v0.2.zip file
- Open a terminal in the folder of the extracted files
- Connect the phone to the PC and select the File transfer option
- Run the script:
- On Windows, type run.bat and press enter
- On Linux, type ./run.sh and press enter
- Now the phone is temporarily rooted and the phone model is changed to RMX3301. Do not reboot or you will lose this status.
- At this point you can follow the procedure on the official forum to unlock the bootloader of the global model. If you already have the Deeptesting app installed, clear its data to make sure it will update.
Changelog:
v0.2:
- Show more info about device for better debug
- Show the model at the end to check if it worked
For technical people: how does it work?
The script abuses a vulnerability of the Linux kernel called Dirty Pipe (or CVE-2022-0847). For further details, you can visit the official website. This allows us to gain temporary root and overwrite the ro.product.name property, the only one checked by the Deeptesting app. The vulnerability is present in Android and it has been fixed, at least for the Pixel 6, in the may 2022 security update. At the time of writing, the latest build for the GT2 Pro is RMX3301_11_A.17, and it's still vulnerable. I have tested the procedure personally up to build RMX3301_11_A.16. If you're on a newer build and it doesn't work, please report it in the comments.
If you have further questions about the procedure, please post them below.3I attached a new version of the script to the OP. This new versions shows more info do better debug problems, and waits 30 seconds before getting the model again to show if everything worked.2
Theoretically you can do everything you can do on a rooted phone (Magisk, but without modules and Zygisk). In practice I never got Magisk to work properly, so I just limited myself to change the property. My goal was to unlock the bootloader, so I did it and installed Magisk.1
My procedure will not delete any data, but after that you have to follow the official procedure to unlock the bootloader, and that will factory reset your phone.1
