Please help me, well to be precise, my father.
I bought a Redmi Note 3 (Hennessy) for him, however we need the multilanguage ROM, because the ROM it shipped with is half English, half Hungarian (I donw't know how). It's on 7.0.919.0 Stable, but even through the Updater app, it won't flash the DEV ROM (miui_HMNote3_6.3.24_41002e2ea6_5.0.zip) donwloaded from the official site, I get this message:
After this, I read thet the MiFlashUnlock can now unlock even being on Stable ROM, so I tried that as well, but at 50%, it says it can't verify the phone (I don't have the English screenshot atm).
ADB drivers seem to be OK as it lists it after adb devices, however, when I reboot to fastboot, the RMN3 vanishes. Is this normal?
I am totaly out of ideas, any suggestions how I can unlock the bootloader to be able to flash the multi rom? Maybe I can flash the DEV ROM with MiFlash?
Any advice would be very appriciated!
