Thank you very much it's seems he work what you send to me:
I was install without problem on C15 domestic realme UI3.0.
After executing, my phone enter in bootloader.
I open powershell.
Next i use: fastboot devices ; phone respond with serial
Next i use: fastboot flashing unlock ; comand respond and phone show me screen with option for unlock.
After that phone automatic restart erase all, reboot in first power on screen.
I enabled again developer and USB debugging.
I check in powershell to see if phone respond with:
adb devices -> OK
adb reboot bootloader -> OK
Now i check Realme_Flash_Tool_v184.108.40.206 to see it's possible to connect PC at phone with LOADING DEVICE button -> succed
Now..... i think what metod to use for change C15.domestic ROM with UI3.0 to whatever GDPR.
I realy think at first move to make, rollback to RMX2202_11.A.20 domestic
