Unfortunately I also i facing the problem you all are debating here. Fortunately my phone is not bricked but I do wish to be able to flash another region firmware and since the bootloader cannot be unlocked on my model, a Realme GT2 European Version, i was looking for ways to flash it using EDL mode. I wanted that because the deep test APK from Realme is available only for the INDIAN version, witch obviously has another firmware.
The only thing that a i haven't tried since now is using the basic QFIL tool from Qualcomm after unpacking the ".ofp" file from the Indian firmware.
Do you guys think the QFIL could finally do this flashing process?
