I recommend retrying this during different times of the day.

Download the attached file, then install manually the driver, select the android_winusb.inf file.
I cannot seem to be able to install this driver manually - can any one help me out with this - tried install via legacy and update driver locating the driver

Edit - Fixed using a driver updater (Driver booster)

Sadly, It seems to work only with Indian Global, not with European Global
I wasn't aware there is an Indian or EU version, thought it was just global or CN. How can you tell the different global versions apart? I purchased mine from eBay and it came with an EU charging brick, is build number RMX3301_11_A.15 and the unlock method worked just fine for me.

Indian global ROM is not the same as European Global rom. In my European device, Global deep testing APK said "Failed to submit application. This phone model does not support deep testing". I'm interested to know if someone with European device unlock successful. Maybe it's a problem with my phone only.

Tried the global app on the European model, and unfortunately I can confirm that it doesn't work, which is pretty disappointing.
I'll reset the phone and configure it, and if in the future they'll allow the unlock also for us I'll do it.

Others have experienced the app fail at first only to succeed on a later try. I read this could be because realme servers are busy sometimes and you just need try at a different time of day. Also saw that restarting the phone before running the app can help as well. Maybe someone can tell me how to confirm my phone is EU model. I'm in the US and purchased from eBay so all I have to go off is the charging brick is an EU electrical plug.

For me the deep test app was stuck on "processing" for 30 min so I clicked "back" then when I checked "query approval status" it gave me "application approved" and an option to start deep testing.

The app fails when? Because it just keeps repeating that the device is not compatible

Does the EU model come with Global rom or is there also a EU rom ? Can anybody confirm if the Global, EU or Indian rom has Call recorder enabled ?
Also does the deeptesting APK work for the base model GT2

A have the GT2 with the GDPR rom witch i suppose it means I have the European version since I live in Europe. Call recording doesn't work since it is illegal in Europe. Also the APK ment for GT2 Pro doesn't work on GT2, i tested it.

    I am not responsible for bricked devices, dead SD cards, etc!

    I have not tested the global unlock, Global version unlock thread.

    Make sure you make backups before unlocking the bootloader, as this operation will wipe all user data and apps.
    Make sure your system version is the official and latest one.


    Requirements

    - 60% charge on the phone
    - PC and usb data cable
    - Installed fastboot and proper drivers on your PC

    1. Install Deep Testing Apk attached in this post.
    2. Click on the Apply Now button in order to get approval for bootloader unlock.
    3. Check the status after apply using the Query Approval Status.
    4. If you get an error, force stop the application, change your device language to Chinese and try again (if someone can post screenshot of what to tap, I would update this post)
    5. Once the approval is done, tap Start Testing button, this will reboot your device in the bootloader.
    6. Last chance, make backups at this point otherwise your data is gone.
    7. Run command
    Code:
    fastboot flashing unlock
    8. Done, you can now reboot into system normally

    If I missed anything, kindly comment and I'll update OP.

    OK I have this working. I believe I will now need to relock the bootloader
    Don't relock the bootloader using the ADB lock command. This will brick your device!

    Same problem. It work for me trying all Chinese languages (simple and another two). It seems stuck for like 30 minutes, then idk why I've exit and re enter the app and it worked.
