I hope i help a lot of people here as i myself spend almost 3 days trying to fix my phone. I followed an outdated tutorial, used wrong android scatter file that wasn't made for my ROM. Corrupted everything on my phone including NVRAM. There is no way i could recover anything. Luckily for MEDIATEK phones we could all fix that and have a good sleep.
